Problems solved by technology

Due to the need for support and lubrication of the synchronous shaft and the limited installation space, it is not possible to connect the synchronous shaft directly to the piston which moves the shaft in the axial direction, since the necessary piston travel cannot be achieved

Embodiment Construction

[0018] In the following drawings, the same reference numerals denote the same or similar components.

[0019] figure 1 A first embodiment of the axial displacement device is shown. The shown device 10 comprises a piston 20 which is movably arranged in the axial direction 16 on an inner guide 24 inside a piston housing 22 which is sealed by a cover 50 , which inner guide 24 For example, it can be designed centrally. The piston housing 22 can be designed, for example, as part of a housing 28 of the vehicle transmission. The piston 20 can thereby move the fork 12 together in the axial direction 16 via the connection 56 . The connection 56 between the piston 20 and the fork 12 can comprise a threaded connection with a seat, protected by adhesive, so that the piston 20 together with the fork 12 forms a stable and strong part. The piston 20 divides the pressure chamber arranged in the interior of the piston housing 22 into a first area 30 and a second area 32 , wherein a further...

Abstract

The invention relates to a device (10) for axially displacing a shaft (18) in a vehicle transmission (14), in particular a vehicle transmission (14) of a utility vehicle, in which device forces are exerted on the shaft (18) of the vehicle transmission (14) in an axial direction (16) via a fork (12), wherein the device (10) comprises a piston (20), which is movable in the axial direction (16), in a piston housing (22), wherein the piston (20) is mounted on an inner guide (24), and wherein an end (26) of the inner guide (24) projects out of the piston housing (22) on one side and, there, is connected to and fixed with respect to a housing (28) of the vehicle transmission (14).

Description

technical field [0001] The invention relates to a device for axially displacing a shaft in a vehicle transmission, in particular a commercial vehicle. Background technique [0002] The disclosure relates to a device for generating a force parallel to a shaft arranged in the interior of a transmission and for transmitting the generated force to the shaft. The shaft can be, for example, a synchronizing shaft, which can be arranged in the vehicle transmission and which has to move parallel to its axis during operation of the transmission. Due to the need for support and lubrication of the synchronizing shaft and the limited installation space, it is not possible to connect the synchronizing shaft directly to the piston which moves the shaft in the axial direction, since the necessary piston travel cannot be achieved. Contents of the invention [0003] The object of the invention is to provide a device which can generate the forces acting on the shaft in the axial direction n...
