In a homokinetic universal joint, an inner joint member extends into the hollow space formed within an outer joint member. Each of the inner and outer joint members has an axially extending check pin located within the hollow space with the pins extending toward one another. The check pins have an axial length which prevent the angular relation between the inner and outer joint members from being less than 20.degree..

Homokinetic universal joint

A constant velocity universal joint comprises an outer joint element having a cavity therein and an inner joint element positioned within the cavity. A plurality of torque transmitting balls are positioned within pairs of opposed grooves formed in the opposing surfaces of the inner and outer joint elements with the grooves being positioned in meridial planes. A ball retaining cage is disposed between the joint elements and has an inner spherical surface coacting with the outer spherical surface of the inner joint member and an outer spherical surface co-acting with a spherical surface portion on the cavity surface of the outer joint element so that the balls are retained in a plane which bisects the angle between the joint elements. The cavity surface and/or the grooves in the cavity surface have a non-undercut configuration in an axial direction with respect to one end of the outer joint member and means are provided on an end of the outer joint element to maintain the cage in coacting relationship with the cavity spherical surface portion.

Constant velocity universal joint

The outer member of a joint is drivingly connected by torque transmitting elements to an inner joint member and has a circumference with a polygonal configuration. A sleeve of a corresponding polygonal configuration is positioned over the outer joint member and is connected to a flange of similar polygonal configuration or to a shaft. The sleeve is retained on the outer joint member against axial displacement by a shoulder or collar on one end of the sleeve and by a detachable ring at the other end of the sleeve.
