Definitions

  • the invention relates to an automatic transmission with at least two planetary gear sets, comprising at least one clutch for shifting gears.
  • the dual-clutch transmissions may have different designs, but at least they have at least one countershaft.
  • automated manual transmission include a clutch actuator and a transmission actuator, so that a manual transmission can be easily converted by the use of the two actuators, a manual transmission in an automatically switchable motor vehicle transmission.
  • the present application relates only to the former type of automatically switchable motor vehicle transmissions, namely the automatic transmission.
  • Such a transmission can be seen for example from DE 199 12 480 A1.
  • DE 103 33 429 A1 shows a multi-stage automatic transmission in cross section.
  • the actuators of the clutches as well as the brakes of an automatic transmission are usually hydraulically actuated, known clutches have a pressurizable piston, with which the clutches are engaged.
  • the clutches and also the brakes in an automatic transmission are thus "normally open” couplings, for actuating the clutches an actuating medium is required, which is usually supplied by the shafts, for which there are rotary feedthroughs at which leakage losses can occur.
  • the present application has the object, an automatic transmission to specify, in which the oil supply is simplified.
  • an automatic transmission of the type mentioned is proposed that is characterized in that the actuating unit of the clutch or clutches has an actuating bearing.
  • the actuating bearing makes it possible to decouple a part of the actuating unit from the co-rotation and thus to be able to modify the oil supply.
  • the actuating bearing preferably as a ball bearing, in particular las
  • Angular contact ball bearings be formed.
  • the actuating bearing can be designed as an axial needle bearing.
  • the actuation bearing different couplings may be the same, but it can also be combined different actuation bearings.
  • an actuation bearing can be designed as angular contact ball bearings and the other as an axial needle bearing.
  • the actuating bearing between a housing fixed portion and a rotatable portion of the actuator unit may be arranged.
  • each component that is supported directly or indirectly on the housing is considered to be fixed to the housing.
  • the rotatable portion of the operating unit is not only rotatable, but also movable in the axial direction.
  • the engagement of a clutch is then carried out by axial movement of both the housing-fixed portion as well as the rotatable portion of the actuator unit.
  • a housing-fixed portion of the coupling can be mounted on a wall of the transmission.
  • the wall is advantageously designed as an intermediate wall, d. H. that it divides the transmission into two subspaces.
  • the wall is thus perpendicular to the longitudinal axis of the transmission.
  • the wall can separate the subspaces of the transmission oil-tight, but it can also be oil-permeable. This of course applies to any medium in the transmission, but usually a transmission oil is used.
  • the supply line of the actuating unit at least in a section in front of the operating unit lead through a wall of the transmission.
  • This is preferably the wall which supports a housing-fixed portion of the coupling.
  • This can be designed as described.
  • the wall can preferably not only receive a supply line, but also the supply lines of other couplings or at least one brake. That is, all wall-mounted clutches and brakes can have at least part of their supply line in the wall.
  • the supply line of the clutch and / or the brake at least partially pass through the wall perpendicular to the longitudinal axis of the transmission.
  • the greater part of the supply line of the coupling, which traverses the wall runs perpendicular to the longitudinal axis of the transmission.
  • the smaller part can run parallel to the longitudinal axis of the transmission.
  • the perpendicular to the longitudinal axis of the transmission extending part of the supply line preferably again runs for the greater part vertically, that is, in the assembled state from top to bottom.
  • the supply lines can also run diagonally. Straight running supply lines are easier to drill.
  • the automatic transmission may preferably have at least two clutches for shifting gears.
  • the automatic transmission can comprise exactly two clutches for shifting gears.
  • These couplings can be arranged coaxially and axially at least partially overlapping.
  • the actuation units of both clutches can have an actuating bearing.
  • the oil supply for both clutches can be simplified.
  • the inner disk carrier of the radially outer clutch can be simultaneously the outer disk carrier of the radially inner clutch. Due to the double assignment, a plate carrier can be completely saved. This is possible although the couplings are completely independent of each other. Even when both clutches are closed, they transmit the torque from the input shaft further, which does not require fully independently operable clutches.
  • the inner disk carrier of the radially outer coupling may be non-rotatably connected to a drive shaft of the transmission. Is the inner disk carrier of the radially outer clutch at the same time the outer disk carrier of the radial inner neren clutch, then this is automatically true for the outer disk carrier.
  • the inner disk carrier of the radially outer clutch is thus an input-side or drive-side disk carrier.
  • the inner disk carrier of the radially inner clutch rotatably connected to a hollow shaft, in particular a hollow shaft of the first planetary gear set be connected.
  • the inner disk carrier of the radially inner clutch may be non-rotatably connected to the web of the first planetary gearset.
  • the clutches also serve to shift gears. Accordingly, they must connect shafts together, so that this torque is transmitted. In the described arrangement, the torque from the input shaft via a coupling to the web of the first planetary gear set is connected.
  • the outer disk carrier of the radially outer clutches can be non-rotatably connected to a hollow shaft, in particular a hollow shaft of the first planetary gear set.
