Title (EN) CROSS-PIECE FOR UNIVERSAL JOINT AND UNIVERSAL JOINT
(FR) CROISILLON POUR JOINT DE TRANSMISSION ET JOINT DE TRANSMISSION CORRESPONDANT
Abstract: front page image
(EN)A cross-piece for a universal joint has a central body (2) to be connected to a shaft and from which a plurality of arms (3) project, a roller (5) rotatably and slidably mounted on each arm (3) by means of an annular pin assembly (4), and a unit (8) for retaining each roller (5) on its respective arm (3). The arm (3) has a hollow circumferential race (12) in which the pins (4) run. The retaining unit has a ring (8) mounted at the end of the arm and spaced from the pins (4), said ring including on the outside and at least on the major portion of its circumference a flange (18) for positively retaining the roller. The invention is useful for constant velocity tripod-type joints for motor vehicle transmissions.
