An actuating device for actuating gear shifting units of a manual transmission has deflectable transmission elements assigned to a respective gear shift unit for changing the gear ratio, a movable actuating element, and gear shift elements assigned thereto. The gear shift elements are movable together with the actuating element and are arranged in two gear shift groups. Dependent on a selecting position of the actuating element, the gear shift elements are coupled with coupling means for deflecting the transmission elements by means of a shifting movement. The shifting movement is independent of the selecting movement. The selecting position can be changed in selecting steps that are delimited by a selecting step length. At least one first gear shift element has an interconnected first gear shift length which is greater than the selecting step length.

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.

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.

The present invention relates to a gear shift arrangement (100) for a transmission arrangement of a vehicle, the gear shift arrangement comprising an axially movable first connecting mechanism (102) connectable to a first gear wheel for engagement of a first gear of the transmission arrangement; an axially movable second connecting mechanism (104) connectable to a second gear wheel for engagement of a second gear of the transmission arrangement; an actuator arrangement (106) configured to controllably connect the first connecting mechanism (102) and the first gear wheel to each other, and to controllably connect the second connecting mechanism (104) and the second gear wheel to each other, wherein the first connecting mechanism (102) comprises a first connector element (108), the second connecting mechanism (104) comprises a second connector element (110) and the actuator arrangement (106) comprises an actuator connector element (112), wherein the second connector element (110) at least partially enclosing the actuator connector element (112), and the actuator connector element (112) at least partially enclosing the first connector element (108), wherein the gear shift arrangement (100) further comprises means (114) for selectively connecting the actuator connector element (112) to the first (108) and second (110) connector elements.

A shift drum has a recess which controls a fork to move one of two cooperating coaxially arranged gears for transmitting torque in a power train of a vehicle. The recess includes a straight section, which upon rotation of the shift drum does not move the fork either to the left or the right, and at least one ramp which does move the fork in one direction (i.e., to the left or the right). The ramp is more complex than a single line, such as having a first portion at a first right-shift portion ramp angle β and a second portion at a second right-shift portion ramp angle γ, perhaps with the intersection between the first right-shift portion ramp angle β and the second right-shift portion ramp angle γ being at the mid-line defined by the straight section of the recess.
