Abstract

A constant velocity fixed joint having an outer joint part, an inner joint part, a cage and torque transmitting balls has the cumulative clearance errors of the joint minimized via the fixing method of supporting inserts. This is achieved in that a ring is provided with at least two fingers pointing axially and radially inward into the cavity of the outer joint part and arranged between two outer running grooves so as to abut the spherical contact face of the cage. While the clearances between the internal joint components are positioned at a predetermined relationship, the ring is positioned at an axial distance from a reference face located at the open end of the outer joint part and that the ring, while observing a predetermined axial play, is connected to the outer joint part. The inner faces of the outer joint part arranged between the outer running grooves thus being held at a predetermined position relative to the spherical outer face of the cage. A method is provided which substantially facilitates handling while individual supporting inserts are attached and which allows the joint play to be set in the specified way. This is achieved in that the outer joint part is provide…
