Problems solved by technology

[0002] In the prior art, the automotive rack and pinion steering gear is mainly composed of three parts: the steering gear housing, the rack, and the steering gear input shaft. Since the rack can slide freely, the rack of the existing steering gear structure may be damaged due to bumps during transportation. It will deviate from the middle position, causing two problems: 1) Multiple adjustments are required to make the rack close to the theoretical center position during online assembly; 2) There is a lack of professional centering equipment for later maintenance, and it is even more difficult to ensure the centering of the rack when installing the steering wheel , often causing the steering wheel to be misaligned when the vehicle is going straight

Embodiment Construction

[0020] In the following, the additional centering mechanism of the rack and pinion steering gear of the present invention will be further described in conjunction with specific embodiments, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0021] Such as figure 1 As shown, the additional centering mechanism of the rack and pinion steering gear of the present invention includes an external thread sleeve 20, an internal thread sliding sleeve 30 and a slide rail sleeve 40, and the length of the external thread sleeve 20 is greater than the length of the internal thread sleeve 30 . Such as Figure 6-7 As shown, the housing of the externally threaded sleeve 20 has an inner wall 25 that axially fits with the input shaft of the steering gear, and the outer wall of the housing is provided with an external thread 21 and is opened to communicate with the inner wall...

Abstract

The invention relates to a centering attached mechanism for a rack and pinion steering gear and belongs to the technical field of automobile design and manufacturing. As non-metal material thread sliding sleeve structures are introduced into the centering attached mechanism for the rack and pinion steering gear and holes are formed in the side surfaces of attached parts, the corresponding side holes are in a coaxial state when the position of a rack is centered, the coaxial state is detected by using a cylindrical pin, and the position of the rack is fixed by using the cylindrical pin in the steering gear assembling process. The centering attached mechanism for the rack and pinion steering gear can guarantee that the rack is enabled to be in a designed middle position by using the corresponding cylindrical pin during assembling the steering gear on a final assembly line or during later maintenance and the rack cannot slide from left to right.
