Abstract
The invention concerns a constant velocity tripod joint for motor vehicle transmission systems comprising a male element ( ) including several branches ( ), a female element ( ) defining for each branch a pair of tracks ( A, B), symmetrical with respect to a plane (P), and, mounted on each branch, a mechanical transmission member ( ) comprising an outer roller ( ) designed to run on one of the corresponding tracks. Each track comprises a central zone ( A, B) having a rectilinear transverse profile and inclined at an angle a relative to the plan (P) and a bearing ( A, B) for maintaining the roller radially. Each roller has a peripheral surface whereof the central zone ( ) is conical and matching the central zones of the tracks, and a front surface ( ) adapted to be urged into contact more or less perpendicularly with said bearing surfaces of the tracks under the effect of a driving torque. The invention is applicable to constant velocity tripod joints for transmission systems in motor vehicles.
