Problems solved by technology

[0005] A disadvantage of a satisfactory solution is, on the one hand, that the stability of the sleeve carrier, and especially the rigidity of its body structure, is negatively affected due to the recess for accommodating the pressure piece

Embodiment Construction

[0028] Figures 1 to 5 A synchronizing device 1 is shown which has a sliding sleeve 2 , a sleeve carrier 3 , a plurality of synchronizing rings 4 , 5 , a gear wheel 6 , a coupling body 7 and a pressure part 8 .

[0029] The sleeve carrier 3 is seated on a transmission shaft (not shown) and engages the transmission shaft by means of a wedge-shaped profile or similarly with a corresponding counter-contour. The sliding sleeve 2 is located on the sleeve carrier 3 . The sliding sleeve 2 has internal toothing, by means of which the sliding sleeve 2 engages into a corresponding mating toothing 31 on the sleeve carrier 3 . The sliding sleeve 2 is arranged longitudinally displaceable on the sleeve carrier 3 . The sliding sleeve 2 , the sleeve carrier 3 and the transmission shaft are connected to one another in a rotationally fixed manner via mutually meshing profiles and toothings, so that the transmission shaft, the sleeve carrier 3 and the sliding sleeve 2 face each other jointly a...

Abstract

The invention relates to a pressure piece (8) for a synchronizing device (1) of a motor vehicle transmission, said pressure piece having a housing (81) and a spring (9) manufactured separately from the housing (81), wherein the housing The body (81) has: a base (82), the axial length of which is greater than that of the spring (9); a cover section (84), wherein the spring (9) is arranged at least partially radially on the cover section Between (84) and bottom (82), the spring (9) extends into the free space (86) and projects radially out of the cover section ( 84).

Description

technical field [0001] The invention relates to a pressure part for a synchronizing device of a motor vehicle transmission, said pressure part having a housing and a profiled spring produced separately from the housing, wherein the housing has a base, the axial length of which is greater than that of the spring The axial length of; the side wall, the side wall at least partially surrounds the spring; and the cover section, wherein the spring is at least partially radially disposed between the cover section and the bottom. Background technique [0002] A pressure piece of this type is described in EP 0 870 941 A1. The resilient locking element is formed on the base body of the pressure part formed from a plate. The locking element in the form of a spring bow is formed from a flat plate of the basic body, protrudes from the pressure piece and is curved in its pressing direction. The basic body of the pressure part is supported on the sleeve carrier radially in the direction ...
