Problems solved by technology

In the state where the bolt B cannot be inserted, even if the axial position of the lower concave portion 2d coincides with the position of the through hole 1d, another problem arises, that is, it is wrongly judged whether the pinion shaft 2 is in the set position.

Embodiment Construction

[0030] The invention will be described below with reference to the accompanying drawings showing embodiments of the invention.

[0031] Fig. 3 shows the coupling structure of the yoke and the shaft according to the embodiment of the present invention. This embodiment is applied where the yoke 10 is connected to the pinion shaft 12 . The yoke 10 has a shaft coupling portion 10a to which a cover 13 is attached, the shaft coupling portion 10a has a U-shaped end face 10k, and the yoke 10 has a structure allowing a pinion shaft 12 to be inserted and connected to the shaft coupling portion 10a.

[0032] The yoke 10 is a metal member having a prescribed rigidity, and is provided in such a structure that the yoke portion 10f is an extension of the shaft coupling portion 10a. Through holes 10d and 10e are respectively provided in wall portions 10b and 10c facing each other on the shaft coupling portion 10a. Further, rectangular groove portions 10h are provided at the portions of the ...

Abstract

A covering member 13 is attached for covering a shaft coupling portion 10a of a yoke 10. Provided at the covering member 13 is an L-shaped salient tongue 13c which projects inwardly of the shaft coupling portion 10a. A groove portion 12f is formed at a bolt-width portion 12a of a pinion shaft 12. The groove portion 12f has a width in the axial direction with a center at a position which opposes the salient tongue 13c when the bolt-width portion 12a is arranged at a set position in the shaft coupling portion 10a. When the bolt-width portion 12a of the pinion shaft 12 is inserted through an opening portion 10g of the shaft coupling portion 10a, insertion is prohibited unless the salient tongue 13c is inserted into the groove portion 12f, so that a problem of poor insertion positioning of a shaft in a yoke is solved.

Description

technical field [0001] The present invention relates to a structure of a yoke and a shaft in which the shaft is connected with a yoke applicable to a universal joint; and more particularly to a coupling structure in which the setting of the shaft is properly accomplished when the shaft is inserted into the yoke so that the shaft and Yoke connection. Background technique [0002] Commonly, universal joints are used as shaft connections within components in vehicle steering systems, such as those used to connect pinion shafts to intermediate shafts, where it is necessary to connect several shafts with bending degrees of freedom. In order to apply such a universal joint, the end of the shaft is connected to a yoke, which forms part of the universal joint. [0003] FIG. 1A shows a general coupling structure of a yoke 1 and a pinion shaft 2 . The yoke 1 has a fork portion 1f integrally connected with a U-shaped shaft coupling portion 1a. Two opposite wall portions 1b and 1c of...
