Abstract
A joint which includes a barrel (1) in which are pivotally mounted four channels (3) defining rolling tracks (5) having a circular cross-sectional shape, adjacent channels defining mutually engaged teeth (7). Received in these rolling tracks are rollers (12) of spherical shape rotatively and slidably mounted on trunnions (11) connected to a shaft (8). Such a joint has, for a given overall size, a torque-transmitting capacity much higher than that of a universal joint and can slide very freely while transmitting torque. It is moreover homokinetic, silent and of relatively low constructional cost, and has application in particular to motor vehicle transmissions.
