Sliding constant-velocity universal joint

Abstract

The present invention provides a slide type constant velocity joint capable of suppressing transmission of a load to a cage when the joint angle becomes the maximum angle. A sliding type constant velocity joint (1) includes an outer ring (2) with a plurality of track grooves formed on the inner surface, and a tripod member (3) that transmits torque between the outer ring (2) and a shaft (7) , a swingable intermediate member (4) supporting the tripod shaft portion (32) of the tripod member (3), a plurality of rolling elements (5) capable of rolling along the outer surface of the intermediate member (4), and The cage (6) holding a plurality of rolling elements (5) limits the radial movement of the intermediate member (4) to the outer ring (2) to avoid The tilting of the intermediate member (4) accompanied by the swing of the tripod shaft part (32) makes the intermediate member (4) contact the neck part (321) or the sleeve part (31) of the tripod shaft part (32) .

Description

[0001] The disclosure of Japanese Patent Application No. 2015-122962 filed on Jun. 18, 2015 including its specification, drawings and abstract is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a sliding type constant velocity universal joint. Background technique [0003] Conventionally, there is known a constant velocity universal joint which is arranged between a side gear which is an output member of a differential device of a vehicle and an intermediate shaft of a propeller shaft, and which does not change even if the angle formed by the two axes of the side gear and the intermediate shaft changes. The two axes can always be rotated at the same speed. [0004] As such a constant velocity joint, there is a slide type constant velocity joint comprising: an outer ring formed in a bottomed cylindrical shape, and three receiving portions extending in the central axis direction are formed on the inner peripheral surf...

AI Technical Summary

Problems solved by technology

At this time, the position of the cage relative to the outer ring is restrained by the locking projections in the track groove of the outer ring, so the cage may be deformed when the load received from the intermediate member is large.

Therefore, for example, the strength of the cage must be ensured by increasing the thickness of the pair of circulation path forming members, which hinders the size reduction and cost reduction of the slide type constant velocity joint.
