Abstract

Official abstract text for this publication.

A fixed type constant velocity universal joint has pairs of track grooves, each pair forming a wedge angle (α). The wedge angle (α) includes a wedge angle (α 0 ) formed, when an operating angle is 0°, with respect to each of torque transmitting balls arranged in a joint center plane, and opening to the same side in an axial direction for all pairs of track grooves. Further, the pairs of track grooves are mirror-image symmetrical with each other when the operating angle is 0°.

First claim

Opening claim text (preview).

The invention claimed is: 1. A fixed type constant velocity universal joint, comprising: an outer joint member having an inner spherical surface provided with a plurality of track grooves extending in an axial direction, and having an opening side and an inner-end side spaced apart from the opening side in the axial direction; an inner joint member having an outer spherical surface provided with a plurality of track grooves extending in the axial direction; torque transmitting…
