A power transmission control apparatus for a vehicle c has a plurality of fork shafts coupled with “sleeves engageable with free-rotating gears”, including first and second fork shafts. When both the first and second fork shafts are in neutral positions, the first and second fork shafts are not coupled in the axial direction so that, while one fork shaft is maintained in its neutral position, the other fork shaft is movable by an actuator from its neutral position to its meshing position. When the one fork shaft is in its neutral position and the other fork shaft is in its meshing position, the first and second fork shafts are coupled in the axial direction so that, when the one fork shaft is moved from its neutral position to its meshing position by the actuator, the other fork shaft is simultaneously moved from its meshing position to its neutral position.

A manual shift transmission is disclosed which includes a shaft, at least one loose wheel carried by the shaft and a gear shift sleeve, which is moveable along the first shaft between a gear position coupling the first loose wheel to the shaft and a neutral position allowing a rotation of the loose wheel against the shaft. A gear shift follower is configured to move the gear shift sleeve along the shaft and acts on the gear shift sleeve. An actuating rod can be shifted in the direction of the shaft for shifting the gear shift follower. The actuating rod carries a clutch body which is adjustable between an active position engaging in a recess of the gear shift follower and a passive position sunk into the first actuating rod.

A shift track selection rod and a shifting element are provided which can be connected to one another without additional fastening elements. A system consists of the shift track selection rod and the shifting element. A transmission actuator includes the system. A transmission includes the system or the transmission actuator.

Shifting device for shifting a transmission, having a first group of shift elements and a second group of shift elements, a selector shaft, which is arranged in such a way that it can be moved in translation along a longitudinal axis and rotated about the longitudinal axis, wherein it is possible, by moving the selector shaft into one of a plurality of possible translational positions, to select at least one shift element of the first group and at least one shift element of the second group and, by rotating the selector shaft, to actuate the selected shift elements. The at least one selected shift element of the first group can be actuated in phase or with an overlapping phase displacement or an offset phase displacement with respect to the at least one selected shift element of the second group.

A drive train (10) for a motor vehicle includes a dual-clutch assembly (14) with a first clutch (K1) and a second clutch (K2), which include a shared input element (EG).

A first actuating unit (S1) is associated with the first clutch (K1), and a second actuating unit (S2) is associated with the second clutch (K2). A transmission arrangement (16) includes a first sub-transmission (32) and a second sub-transmission (34). An input shaft (24) of the first sub-transmission (32) is connected to the first output element (AG1), and an input shaft (26) of the second sub-transmission (34) is connected to the second output element (AG2). The second actuating unit (S2) is associated with the second clutch (K2) of the dual-clutch assembly (14) as well as with a gearshift clutch (C; E) of the first sub-transmission (32), and/or the first actuating unit (S1″) is associated with the first clutch (K1) of the dual-clutch assembly (14) as well as with a gearshift clutch (F) of the second sub-transmission (34).

In a vehicle drive transmission device, a transmission includes an intermesh first engagement device, a frictional second engagement device, a first drive device configured to drive the first engagement device, and a second drive device configured to drive the second engagement device. The first drive device includes a first shift drum, a first cam mechanism configured to convert rotational motion of the first shift drum into linear motion, and a first transmission mechanism configured to perform the linear motion. The second drive device includes a second shift drum, a second cam mechanism configured to convert rotational motion of the second shift drum into linear motion, and a second transmission mechanism configured to perform the linear motion. The first shift drum and the second shift drum are connected so as to rotate integrally with each other via a drive shaft. A drum drive source is provided to drive the drive shaft.

A drive mechanism that drives an axially moving portion in an axial direction includes a drive portion that reciprocates a first member along an intersecting direction that is a direction that intersects the axial direction, a conversion portion that converts a reciprocating motion of the first member along the intersecting direction into a reciprocating motion of a second member along the axial direction, and a connecting portion for connecting the second member and the axially moving portion such that the axially moving portion reciprocates along the axial direction as the second member reciprocates along the axial direction.

An actuating unit for actuating shift elements of a transmission (G) includes a shaft (1) at least partially configured as a hollow shaft and at least three shift elements (A, B, C, D). At least two of the at least three shift elements are spatially separated from each other by at least one of the three shift elements. A first actuating element (S1) is configured as a hollow shaft and a second actuating element (S2) is guided within the first actuating element (S1). A mechanical coupling of the two actuating elements (S1, S2) with the at least three shift elements (A, B, C) takes place through a plurality of recesses (11, 12, 13) in the shaft (1) and through at least one recess (21) in the first actuating element (S1) in such a way that the at least two shift elements (A, B, C, D) spatially separated from each other are actuatable by precisely one of the two actuating elements (S1, S2).
