Abstract:
A joint for transmitting shifting forces from a gear-shifting system of a transmission to a transmission drive member, the joint comprising:a first joint part (1) frictionally connected to the transmission drive member;a second joint part (2) connected to the gear-shifting system;a coupling (3) mounted between the first and second joint parts (1, 2); andan elastically deforming device comprising a one-piece elastically deforming damper (4) substantially enclosing the coupling (3) and keeping the coupling spaced apart from the first and second joint parts in the absence of the shifting forces,wherein the coupling (3) is a spider comprising two substantially mutually orthogonal and spaced-apart sections (3a, 3c) and a borehole (3b, 3d) disposed in each section,wherein each of the first and second joint parts (1, 2) includes a borehole (6a, 7a), the joint further comprising a pair of joint pins (5a, 5b) passing through one of the spider boreholes (3b, 3d) and one of the first and second joint part boreholes (6a, 7a), the first and second joint part boreholes (6a, 7a) being disposed relative to the spider boreholes (3b, 3d) so that the spider (3) is mounted spaced from outside walls of the first and second joint parts (1, 2),further comprising bushings (8) mounted between the spider (3) and the joint pin (5),wherein the damper (4) keeps the spider (3) at a spacing from the bushings (8) when the joint is not transmitting the shifting forces.
