ABSTRACT:
A sliding transmission joint intended for motor vehicles, which includes a tripod (1) locked in rotation with a driving shaft (2) and provided with three radial arms (3) capable of sliding axially on flat rolling tracks (22) provided inside a drum (5). The drum 5 is locked in rotation with a driven shaft, rows of needle rollers (7) are arranged between the arms (3) and the rolling tracks (22), and also cages (14) are provided for holding the rows of needle rollers (7). The cages (14) having projecting members (16) which are used for attaching the cages (14) to the drum (5) and which are accommodated in corresponding recesses (15) formed in the drum. The arrangement of the projecting members 16 and recesses 15 ensures that the cage (14) is guided perfectly as far as the end of the extension of the driving shaft (2), and reduces the weight of the joint by eliminating projecting parts (28) between two internal adjacent shoulders of the rolling tracks.
