Abstract: A sliding universal joint comprises a male element (1) intended to be fixed to a first shaft and including arms (6). Each arm bears a ball-type journal (7) which is integral therewith. A female element (20 intended to be fixed to a second shaft defines two guide paths which are situated on either side of each journal. Intermediate member (3, 4) are interposed between each journal and the associated guide paths. These intermediate members comprise a first member (3) which interacts with a first path (8) of the guide paths and has properties, with respect to the transmission and/or generation of vibration, which are different from those exhibited by the interaction between the second member (4) and the second guide path.

Abstract: An intermediate roller element for a universal joint includes a strip (12), one face of which includes at least one longitudinal roller track and balls (20) which roll along the track. The balls are held by a cage (22) produced in the form of a plate (24) which extends in a plane substantially parallel to the overall plane of the track (16), and includes cells in which the balls (20) are received. The cage includes portions (28, 32, 34) joining the cage (22) to the strip in order to form a unitary sub-assembly.
