- so-called parallel shift transmission also called PSG
- dual-clutch transmissions in which only the even gears and with the other shift mechanism and the other clutch of the dual clutch, the odd gears are connected with a shift mechanism and with a clutch of the dual clutch.
- the odd gear is alternately switched with the one shift mechanism while the other shift mechanism already preparing the next straight gear.
- the first clutch is engaged and the other clutch is disengaged
- the odd gear is engaged in the power flow.
- one clutch is disengaged and the other clutch engaged, it is possible to shift quickly from the odd gear to the next even gear.
- transmissions with shift drum gears or other positive link transmissions are known in which a positive coupling between the respective actuations ensures that the number of actuators is reduced.
- Such transmissions have also become known through WO 97/02963. Due to the positive coupling, however, the transmission is limited with its operation, because the stored in the positive coupling switching sequence must be adhered to.
- An embodiment of the invention provides a transmission with a predetermined number of gear ratios, which are divided into two groups of gear ratios, each group of gear ratios actuation means and a Actuator is assigned, by means of which the gear ratios of the respective group can be selected and inserted, wherein each group of gear ratios, a clutch is assigned to connect the gear ratio with a drive train, wherein the clutch associated with the group associated with the group actuating means and actuator for Selecting and inserting the translation stage is operated.
- both the insertion of the gear ratios and the actuation of the clutch is made by means of an actuator, so that the number of actuators can be advantageously reduced.
- the actuating means comprise switching elements, wherein the insertion of a gear ratio from the group of gear ratios is effected by operating a switching element, wherein a selection of the gear ratio is made by selecting one of the switching elements. This achieves a facilitated selection and actuation process.
- the actuating means comprise switching elements, wherein the actuation of the clutch of the group is effected by actuating a switching element, wherein a selection of the actuation of the clutch takes place by selecting one of the switching elements.
- the switching element can be connected directly or indirectly with the coupling.
- the indirect connection can be made, for example, by means of further elements, such as an engagement system, an engagement bearing, levers, rods, etc.
- the actuating means for the actuation of the clutch is first actuated or moved in a direction opposite to the direction of actuation, and then the actuating means is actuated or moved in actuation direction by actuation of the actuating element.
- a travel extension for the clutch actuation can be achieved because only without the clutch to operate in the opposite direction can be moved and, for example, only at the end of the operation in the opposite direction, the operation of the clutch can be started.
- an activation element is activated between the actuation in the opposite direction of the actuation and the actuation in the actuation direction. This can be activated with the activation of the input or disengagement of the clutch.
- the actuating element is a shift rod or a shift rail and an actuation of a shift rod or shift rail is a displacement or rotation of the shift rod or shift rail.
- a displaceable element on a fixed rod or rail can be used.
- an inserted translation stage is designed, if another translation stage of the same group or another group is inserted.
- an actuator has exactly one or at least one drive motor for selecting and for actuating the actuating element.
- the actuator has a drive motor, wherein upon rotation in the one direction of rotation a selection takes place and upon rotation in the other direction of rotation an actuation takes place.
- the invention also relates to a method for controlling a transmission.
- the present invention will be explained in more detail below with reference to preferred exemplary embodiments in conjunction with the associated figures:
- Figure 1 is a schematic view of a transmission
- Figure 2 H-circuit diagrams
- Figure 3 is a H-circuit diagram
- the first group G1 comprises the transmission stages 1, 3, 5 and 7, wherein the second group G2 of transmission stages comprises the transmission stages 2, 4, 6 and the reverse gear R.
- first group G1 of gear ratios associated with the clutch K1 and the second group G2 of gear ratios is associated with the clutch K2.
- the transmission 1 is designed such that the first group G1 of translation stages associated with actuating means 2, which are actuated by means of the actuator 3 to select a translation stage from the gear ratios and then insert this gear ratio or press.
- Actuating means 4 are likewise associated with the second group of translation stages, which can be selected and actuated by means of an actuator 5 in order to select and translate a translation stage from the group of translation stages. make or select.
- the clutches K1 and K2 are further associated with actuating means 6, 7, by means of which the clutches K1 and K2 are actuated, such as on or disengaged.
- the actuating means by Betuschists appearing. Switching elements 8, 9, 10 and 1 1, 12, 13 formed, for example, interact with actuating fingers. By actuating the actuation or switching elements 8 to 10 or 1 1 to 13, a gear ratio can be selected from the group of gear ratios by operating the switching element and the selected gear ratio can be actuated or engaged.
- the clutch can be selected or actuated by actuation of the actuating or switching element, which means a disengagement or engagement of the clutch.
- actuating means or the switching elements these can either be displaced axially or alternatively also be rotated.
- the switching elements are designed as shift rails or shift rails, which are moved in the axial direction of the shift rails or shift rails. If the switching element 9 designed as a shift rod or shift rails is actuated in the axial direction, then the first gear stage can be engaged in the one direction of actuation, or the third gear stage can be engaged in the other direction of actuation.
- either the fifth gear ratio or the seventh gear ratio can be engaged.
- either the second or the fourth gear ratio can be actuated by the operation of the switching element 12, depending on the direction of actuation or upon actuation of the switching element 13 can either the sixth gear ratio or the Reverse gear are engaged.
- An actuation of the clutch is effected by the switching element 8 and the switching element 1 1, which are also designed as so-called shift rods or shift rails, wherein the actuation of the clutch takes place by an axial actuation of the shift rods 8, 1 1 or shift rails in an actuating direction.
- FIG. 2 shows the representation of H circuit diagrams for the two groups G1, G2 of transmission stages.
- a H-circuit diagram is shown for the translation stages 1, 3, 5, 7, that is, the odd gear ratios, wherein the gear ratios are inserted in an operation substantially to the end of the shift gates 20.
- the switching element is actuated by an actuating means 21, wherein a rotation of the actuating means 21 causes an engagement of the translation stage and causes an axial lifting or lowering of the actuating means selecting the alley.
- a translation stage can be inserted or designed by the actuating movement in a lane 20 and at an actuating movement perpendicular to a shift gate, according to the selector gate 22, a shift gate or a transmission ratio can be selected.
- the actuation of a selection of a translation stage thus takes place with a movement along the alley 22 and the insertion of a translation stage is carried out by actuation in an alley 20, wherein the actuation of the coupling is converted into an actuation in the alley 23.
- the H-circuit diagram of the right subfigure of Figure 2 shows substantially the same ratios for the gear ratios 2, 4, 6 and the reverse gear and the operation of the clutch K2.
- 3 shows an H-circuit diagram 30, in which, according to the H-circuit diagram of Figure 2 for the gears 1 to 7, the shift gates 31 are provided to switch the gear ratios 1 to 7, between these shift gates 31, a shift gate 32nd is provided, in which is actuated to actuate the clutch.
- the shift gate 32 is formed in both directions from the Wählgasse 33, wherein a first method of the actuating element takes place in the opposite direction to the clutch operation according to the line 34, at the end of the alley 32 in the area 35 is a switching and then over the full length of the Weggasse 32, according to the line 36, a clutch actuation of the clutch K1 of the group G1 takes place.
- a clutch actuation with an approximately doubled actuating travel This can be advantageous in clutch operations that require a longer path with less force.
- FIG. 4 which is subdivided into subfigures 4a and 4b, represents a schematic representation of a method for carrying out a switching operation. Starting from the two H circuit diagrams of FIG. 2, the following is in the first line of FIG. 4a the switching process explained.
- the actuating means for the second group is in the selector gate, see position 53.
- the first gear ratio has been inserted. Due to the non-immediate interpretation of the first gear stage in a backward movement of the actuating means, the actuating means can be moved into the shift gate of the clutch actuation in the third line of Figure 4a, after inserting the first Ü translation stage, so that after inserting the first gear stage, the clutch K1 for the first group of translation stages can be actuated to effect a torque transfer when the first gear ratio is engaged.
- the actuating means is then moved from the Kupplungsbetuschistsgasse in the alley for the third gear stage and the third gear ratio is engaged, which in turn is ineffective, as long as the clutch K1 is still disengaged.
- the first transmission stage from the group of the first transmission stages is designed, for example, via the so-called "active interlock" device with the associated auxiliary actuating means. If no active interlock device is used, the actuator first applies all the gears or gear ratios of the group before the new gear ratio is switched.
- the torque transmission thus takes place via the second transmission stage and the clutch K2 of this group G2.
- the actuation of the fourth transmission ratio is subsequently selected and carried out, so that in this process the second transmission stage is designed via the "active interlock" mechanism.
- the clutches of the transmission are preferably clutches that are open in the non-actuated state, so do not transmit torque. It is particularly preferred if the clutch remain free of force in this position and not automatically engage again. For this purpose, if necessary, stops or a detent are provided, which leaves the clutch to remain in the open position so that it does not inadvertently, for example, engages by itself
- the clutch is preferably actuated by means of an actuating device between the actuating element and the clutch. It can be provided between the actuating means, for example, a lever, an engagement bearing, an engagement system and / or a fluid actuation path with donor and / or slave cylinder.
