ABSTRACT:
A cross groove type of constant velocity ratio universal joint, comprising an outer joint member (1), an inner joint member (2), and a cage (3) constraining torque transmitting balls (4) received one in each pair of facing grooves (8, 14) in the outer and inner joint members, the grooves being inclined to the axes of the joint members so as to cross one another, wherein the cage is of asymmetrical configuration, comprising at one end an opening of a diameter greater than an outside diameter of the inner joint member, and at its other end and opening of a diameter smaller than the outside diameter of the inner joint member. The external surface of the cage comprises a number of surface portions (S1 to S5) of different configuration from one another. The configuration of the cage facilitates assembly of the joint and also permits an extended range of plunging movement in one direction, while limiting plunging movement in the opposite direction.
