Description
Technical Field
The invention relates to a hybrid module for a motor vehicle (hybrid) drive train, comprising a housing, an input shaft mounted in the housing for introducing torque generated by a first drive machine (for example an internal combustion engine or an electric machine), a rotor carrier for introducing torque generated by a second drive machine (for example an electric machine), a separating clutch for the rotational coupling of the input shaft to the rotor carrier, a clutch for the rotational coupling of the rotor carrier to an output shaft, and a hydraulic actuating system for actuating the separating clutch, wherein the actuating system comprises an actuating cylinder and an actuating piston axially accommodated in the actuating cylinder in a displaceable manner.
Background
Hybrid modules are known by way of background. For example, DE 10 2009 059 944 A1 discloses a hybrid module for a motor vehicle drive train, comprising a first separating clutch, an electric motor and a second separating clutch, wherein the first separating clutch is arranged in the torque flow between an internal combustion engine and the electric motor in the drive train and the second separating clutch is arranged in the torque flow between the electric motor and a housing in the drive train, wherein the first separating clutch and the second separating clutch are arranged in a common wet chamber.
Another document DE 10 2007 008 946 A1 also discloses a clutch system for a motor vehicle drive, comprising at least one clutch input and at least two transmission input shafts, wherein each transmission input shaft is connected to the clutch input via a separate liquid-cooled and lubricated friction clutch, wherein each friction clutch has a friction plate set arranged between an inner friction plate carrier and an outer friction plate carrier, and wherein the friction plate sets are spatially arranged next to one another, wherein the inner friction plate carrier is connected to the clutch input in a rotationally rigid manner at least, wherein each outer friction plate carrier is connected to one transmission input shaft in a rotationally fixed manner at least, wherein the clutch system has at least two clutch inputs, wherein one clutch input is a clutch input shaft and the other clutch input is an outer friction plate carrier, and wherein the clutch input shaft is operatively connected to the internal combustion engine, and wherein a rotor of the electric drive is arranged on the outer friction plate carrier.
A hybrid module for a drive train of a motor vehicle is also known from DE 10 2017 129 873 A1, which has not yet been published, comprising a housing, a separating clutch, a hydraulic actuating unit which acts together with the separating clutch and is accommodated on the housing, and an electric motor, wherein a rotor of the electric motor is coupled in a rotating manner or in a rotating manner to a clutch assembly of the separating clutch, and wherein the actuating unit has a piston unit which is accommodated in a displaceable manner relative to the housing and is connected in an anti-displaceable but relatively rotatable manner to a pressure element for engaging and disengaging the separating clutch by means of an actuating bearing in the axial direction of the separating clutch, characterized in that the actuating bearing is designed as an axial needle bearing.
However, the prior art always has the disadvantage that the installation space for mounting the three clutches is very limited, in particular in the axial direction, in particular in a hybrid module which comprises three clutches, i.e. one disconnect clutch and one double clutch, and which comprises an electric machine arranged coaxially. Thus, the currently known three clutch scheme cannot be used.
Disclosure of Invention
It is therefore an object of the present invention to avoid or at least mitigate the disadvantages described in the background. In particular, a hybrid module is to be provided in which the clutch and its operating device can be integrated in a particularly space-saving manner.
According to the invention, the object is achieved in such a device in that the actuating cylinder of the clutch actuating device is formed by a component which is fixed by a rotor carrier. This has the advantage that no additional components for forming the actuating cylinder have to be installed in the existing installation space. The actuating system of the separating clutch can thus be integrated in a particularly space-saving manner, since the actuating chamber is to be formed using components already present, for example a rotor carrier. The operating system can thus be manufactured in an axially short manner.
It is particularly advantageous if the component to which the rotor support is fastened is an integral component of the rotor support, i.e. of the same material. Therefore, the shape of the rotor support is used to define the operating chamber.
It is also advantageous if the rotor support is of one-piece or multi-piece design. The rotor support can thus be produced at low cost, even when the geometry is relatively complex. For example, it is advantageous if the segments of the rotor support are welded to one another for forming the rotor support.
According to a preferred embodiment, the radial outer diameter and/or the radial inner diameter of the actuating cylinder is formed by the rotor support. In this way, the actuating piston, which is designed, for example, as a pressure tank, can be moved in an advantageous manner along the outer diameter and/or the inner diameter in an axially and radially guided manner. Thus, the operating piston moves with the rotation of the operating cylinder, i.e., the rotor bracket.
According to an advantageous development, the actuating piston can have a preferably injection-molded seal on the radially outer and/or radially inner side in order to close the gap between the actuating piston and the actuating cylinder in a sealing manner. Thereby preventing leakage of operating fluid/hydraulic fluid from the operating chamber
It is also advantageous if the disconnect clutch and/or the clutch actuating system is designed as a swivel joint. The installation space of the operating system can thus be kept relatively small.
It is also advantageous if an opening is provided in the rotor support, through which hydraulic fluid can be introduced into the actuating chamber enclosed by the actuating cylinder and the actuating piston. Hydraulic fluid can thereby be introduced from the stationary housing into the rotating rotor support.
According to an advantageous further development, the hybrid module can have at least one piston ring, which is arranged in the radial direction between the housing and the rotor carrier, for sealing the gap between the hydraulic line and the opening. In this way, hydraulic fluid is advantageously reliably guided from the housing into the rotor support.
In a particularly preferred embodiment, the clutch can be designed as a double clutch comprising a first partial clutch and a second partial clutch, wherein the first partial clutch is connected or connectable to the first transmission input shaft and the second partial clutch is connected or connectable to the second transmission input shaft in order to transmit torque.
It is also advantageous if the hybrid module has a restoring spring for applying a restoring force which counteracts the operating force of the operating piston. In this way, it is advantageously ensured that the actuating piston is reset when the actuating pressure is switched off.
Furthermore, it is advantageous if the hybrid module has a compensation chamber for compensating the actuating forces of the actuating piston, which are generated by the centrifugal force. It is also advantageous if the balancing chamber is filled with oil, so that the oil pressure in the balancing chamber exerts a force in the axial direction on the axially movable operating piston for operating the separating clutch. The force thereby counteracts the operating force. In this way, it is avoided in a simple manner that the operating oil which remains in the operating chamber and is pressed radially outward by the centrifugal force induced by the rotation accidentally operates the clutch. That is, the oil in the balancing chamber counteracts this unexpected force in the axial direction.
It is particularly advantageous if the return spring and/or the compensation chamber extend at least partially into an axial installation space radially inside the disconnect clutch. That is, the return spring and/or the balance chamber are arranged radially inside the separating clutch. That is, the return spring and/or the balancing chamber are at least partially arranged at the same axial level as the separating clutch. In this way, the restoring spring and/or the compensation chamber can be integrated in the hybrid module, with little additional installation space, in particular in the axial direction.
It is furthermore advantageous if the return spring and/or the compensation chamber are arranged radially inside the first sub-clutch and/or extend at least partially into an axial installation space of the first sub-clutch. This provides a solution which is particularly space-saving in the axial direction.
In a preferred embodiment, the hybrid module can have a bearing which rotatably supports the rotor carrier in the housing. According to an advantageous development, the return spring and/or the compensation chamber can be arranged radially outside the bearing and/or at least partially extend into an axial installation space of the bearing. That is, the existing space between the disconnect clutch and the clutch bearing will be fully utilized to house the operating system components.
It is therefore particularly preferred that the first sub-clutch, the separating clutch, the return spring, the compensation chamber and/or the bearing are arranged in a radially nested manner. That is to say that the components are arranged at least partially at the same axial level in a radially offset manner only. A particularly compact design is thereby achieved.
It is particularly advantageous if the hybrid module has an electric machine which is used as the second drive machine and is arranged coaxially with respect to the hybrid module. In particular in coaxial electrical machines, it is advantageous to make full use of the space radially inside the rotor of the electrical machine and to produce it in an axially as short a manner as possible.
In other words, the present invention relates to a hybrid module comprising three clutches. The three clutches have a disconnect clutch for connecting/disconnecting the internal combustion engine to/from the drive train and a double clutch comprising a first sub-clutch and a second sub-clutch. The dual clutch is used to connect/disconnect the hybrid module with the transmission, wherein the dual clutch is arranged downstream in the torque flow with respect to the disconnect clutch or the hybrid module. According to the invention, the disconnect clutch is actuated by a rotary joint integrated in the rotor carrier of the hybrid module. Preferably, the rotor carrier forms the inner and outer diameters of the hydraulic cylinders for actuating the separating clutch. According to the invention, a restoring spring and/or a compensating space is also arranged radially outside the clutch fixing bearing and radially inside at least one of the clutch and the clutch.
Drawings
The invention will be described hereinafter with the aid of the accompanying drawings. Brief description of the drawings:
FIG. 1 is a longitudinal cross-sectional view of a hybrid module according to the present invention, and
Fig. 2 is an enlarged partial view of the hybrid module shown in fig. 1.
Detailed Description
The drawings are merely schematic in nature and are merely intended to aid in the understanding of the invention. Like elements are provided with like reference numerals.
Fig. 1 and 2 show a hybrid module 1 according to the invention, which is suitable for a drive train 2 of a motor vehicle. The hybrid module has a housing 3 in which an input shaft 4 is rotatably supported. The input shaft 4 is designed to introduce torque generated by a first drive machine, for example an internal combustion engine, into the hybrid module 1. The hybrid module 1 has a rotor carrier 5 which is designed to introduce a torque generated by a second drive machine, for example an electric machine.
The input shaft 4 is connected in a switchable manner to the rotor carrier 5 via a disconnect clutch 6. By disengaging the clutch 6, the input shaft 4 and thus the first drive machine can be decoupled from the drive train 2 (or coupled to the drive train 2). The rotor support 5 is connected to an output shaft 8 via a clutch 7. The hybrid module 1 additionally has a hydraulic operating system 9 for operating the disconnect clutch 6. The operating system 9 comprises an operating cylinder 10 and an operating piston 11 which is axially accommodated in the operating cylinder 10 in a movable manner. The actuating piston 11 interacts with the separating clutch 6 in order to set, i.e. open or close, the separating clutch 6 when the actuating piston 11 is moved axially. The disconnect clutch 6 is designed as a multiplate clutch/multiplate clutch.
The directional designations "axial", "radial" and "circumferential" in the following relate to the central rotational axis/longitudinal axis L of the hybrid module 1. Thus, "axial direction" refers to a direction along the rotation axis L, "radial direction" refers to a direction perpendicular to the rotation axis L and "circumferential direction" refers to a direction along a circumferential line extending concentrically around the rotation axis L.
The operating system 9 is designed as a swivel joint 12. Hydraulic fluid for operating the disconnect clutch 6 is introduced into the housing 3 through the hydraulic conduit 13 and into the operating chamber 14 through the rotor carrier 5. The operating chamber 14 is surrounded by the operating cylinder 10 and the operating piston 11. When pressure is applied to the operation chamber 14 by the hydraulic fluid, the operation piston 11 moves in the axial direction of the hybrid module 1.
The operating cylinder 10 is constituted by the rotor bracket 5. The rotor support 5 may be of one-piece design, even if not shown. In the embodiment shown, the rotor support 5 is of a multi-piece design. The parts of the rotor support 5 are for example welded to each other. The rotor support 5 forms a radial outer diameter 15, a radial inner diameter 16 and an axial end face 17 of the actuating cylinder 10.
The operating piston 11 is moved when pressure is applied along the outer diameter 15 and the inner diameter 16. The operating piston 11 has seals 18 on its axially outer side and radially inner side for outwardly sealing the operating chamber 14. The seal 18 is injection molded onto the operating piston 11.
When pressure is applied to the operating chamber 14, the operating piston 11 is moved by the hydraulic fluid against the restoring force of the restoring spring 19. The operating piston 11 acts as a pressure tank, pressing against the separating clutch 6. When the pressure in the operating chamber 14 is relieved, the operating piston 11 is moved back to its starting position by the restoring force of the restoring spring 19. The balance chamber/compensation chamber 20 is arranged on the side of the operating piston 11 opposite the operating chamber 14 in the axial direction. The return spring 19 is arranged in the balancing chamber 20. In the balancing chamber 20 there is hydraulic fluid which counteracts the accidental operation of the operating piston 11. The operating piston 11 separates the operating chamber 14 from the balancing chamber 20 in the axial direction. The balancing chamber 20 is delimited on one side in the axial direction by the operating piston 11 and on the other side in the axial direction by the centrifugal oil cap 21. The centrifugal oil shield 21 is designed as a sheet metal component with a plastic-sprayed seal.
The rotor holder 5 is rotatably supported in the housing 3 by a first bearing 22. The first bearing 22 is located on the radially outer side of the housing 3 bearing cap 23. The first bearing 22 is designed as a fixed bearing. The input shaft 4 is rotatably supported in the housing 3 by a second bearing 24. The second bearing 24 is designed as a fixed bearing.
The return spring 19 and the first bearing 22 are arranged in a radially nested manner. The return spring 19 and the first bearing 22 are (at least partially) at the same level in the axial direction. That is, at least a portion of the return spring 19 may extend into an axial region of the first bearing 22 defined by an axially outer edge of the first bearing 22 (e.g., an inner ring and an outer ring of the first bearing 22). The return spring 19 is arranged radially outside the first bearing 22.
The balance chamber 20 and the first bearing 22 are arranged in a radially nested manner. The balance chamber 20 and the first bearing 22 are (at least partially) at the same level in the axial direction. That is, at least a portion of the balance chamber 20 may extend into an axial region of the first bearing 22 defined by an axially outer edge of the first bearing 22 (e.g., an inner ring and an outer ring of the first bearing 22). The balance chamber 20 is arranged radially outside the first bearing 22.
The clutch 7 is designed as a double clutch 25. The clutch 7 has a first partial clutch 26 and a second partial clutch 27. The first split clutch 26 may be connected to a first transmission input shaft 28, which is used as the output shaft 8, for transmitting torque. The second split clutch 27 may be connected to a second transmission input shaft 29, which is used as the output shaft 8, for transmitting torque. The first split clutch 26 is designed as a multiplate clutch/multiplate clutch and is operated by a swivel joint 30. The second partial clutch 27 is designed as a multiplate clutch/multiplate clutch and is operated by means of a swivel joint 31.
The first sub-clutch 26 is arranged in a radially nested manner with the return spring 19. The return spring 19 and the first sub-clutch 26 are (at least partially) at the same level in the axial direction. That is, at least a portion of the return spring 19 may extend into an axial region of the first sub-clutch 26 defined by an axially outer edge of the first sub-clutch 26 (e.g., friction plates of the first sub-clutch 26). The return spring 19 is arranged radially inward of the first sub-clutch 26.
The first sub-clutch 26 is arranged in a radially nested manner with the balance chamber 20. The balance chamber 20 and the first sub-clutch 26 are (at least partially) at the same level in the axial direction. That is, at least a portion of the balance chamber 20 may extend into an axial region of the first sub-clutch 26 defined by an axially outer edge of the first sub-clutch 26 (e.g., friction plates of the first sub-clutch 26). The balance chamber 20 is arranged radially inward of the first sub-clutch 26.
The separating clutch 6 is arranged in a radially nested manner with a return spring 19. The return spring 19 and the separating clutch 6 are (at least partially) at the same level in the axial direction. That is, at least a portion of the return spring 19 may extend into an axial region of the disconnect clutch 6 defined by an axially outer edge of the disconnect clutch 6 (e.g., friction plates of the disconnect clutch 6). The return spring 19 is arranged radially inward of the separator clutch 6, for example radially inward of the friction plate carrier in the separator clutch 6.
The disconnect clutch 6 is arranged in a radially nested manner with the balance chamber 20. The balance chamber 20 and the disconnect clutch 6 are (at least partially) at the same level in the axial direction. That is, at least a portion of the balance cavity 20 may extend into an axial region of the disconnect clutch 6 defined by an axially outer edge of the disconnect clutch 6 (e.g., friction plates of the disconnect clutch 6). The balancing chamber 20 is arranged radially inside the separator clutch 6, for example radially inside the friction plate carrier in the separator clutch 6.
To operate the disconnect clutch 6, hydraulic fluid is introduced into the housing 3 through a hydraulic conduit 13. The hydraulic line 13 has a radial section through which the hydraulic fluid passes into the gap between the housing 3 and the rotor support 5. The gap is sealed by piston rings 32. The hydraulic fluid can thus pass from the stationary housing 3 through the radial openings 33 in the rotating rotor support 5 into the operating chamber 14. The actuating chamber 14 is enclosed by the rotor support 5 or a rotor support-mounted component designed as actuating cylinder 10 and actuating piston 11. The operating piston 10 is therefore designed as a rotating component. When pressure is applied to the operating chamber 14, the operating piston 11 is moved in the axial direction away from the operating cylinder 10 against the return spring force. Thereby operating the disconnect clutch 6.
