Problems solved by technology

[0009] In the prior art mentioned above, since the multi-part linkage mechanism 204 and the universal coupling 211 are used to change the rotation angle of the steering shaft 206 relative to the rotation angle of the steering shaft 202, the structure of the steering device 200 is complicated. thus requiring a simplification of the structure
In addition, since the centerlines A1 and C1 of the steering shaft 202 and the steering shaft 206 are inconsistent, a large moment will act on the link mechanism 204 that transmits the rotational force. Therefore, in order to improve the rigidity of the link mechanism 204, For example, the cross-sectional area of ​​each component part will have to be increased, resulting in an excessively large shape

Abstract

The vehicle is structured so that a steering shaft 12 is installed rotatably on a body frame, a tie rod and a knuckle arm are installed in the lower part of the steering shaft 12 through a steering arm 66, and wheels are mounted on the knuckle arm rotatably, wherein the steering shaft 12 is divided into a plurality of shaft sections (an upper shaft 71, a middle shaft 73, and a lower shaft 75), which are coupled together by hook type joints (a first hook joint 72 and a second hook joint 74).

Description

technical field [0001] The invention relates to a vehicle steering device. Background technique [0002] In the prior art, as a vehicle steering device, a steering shaft divided into two is connected by a link mechanism (for example, see Patent Document 1). [0003] [Patent Document 1] Patent Publication No. 2002-127981 [0004] Through the following figure 12 (a), (b) to the patent document 1 Image 6 (a), (b) for illustration. And change the label. [0005] Fig. 12 (a), (b) is the side view showing the main part of the existing vehicle steering device, in figure (a), as the front wheel direction control device 200 of the steering device, it can be freely mounted on the front fork pipe 201. The steering shaft 202 is rotatably installed, the connecting part 203 is installed on the lower part of the steering shaft 202, the steering shaft 206 is installed on the connecting part 203 through the link mechanism 204, and the steering shaft 206 is connected to the front wheel si...
