Problems solved by technology

[0003] Research and investigation found that the main reason is that in the process of long-term use, the lubrication effect in the steering gear decreases with time, resulting in poor lubrication effect between the pinion shaft and the rack, and then the pinion shaft and the rack are in transmission. Occurrence of abnormal noise and stagnation

Abstract

The invention provides a gear shaft for an automobile steering device. The gear shaft for the automobile steering device comprises a steering device body (1) and a gear shaft body (2), wherein the gear shaft body (2) comprises a transmission part (21) arranged inside an inner cavity (3) of the steering device body (1) and an extending part (22) extending out of the inner cavity (3), the extendingpart (22) is connected with a steering wheel, the transmission part (21) is provided with a tooth face (23) matched with a toothed bar (4), and the inner cavity (3) is sealed and filled with lubricating oil. According to the gear shaft for the automobile steering device, the steering device inner cavity is filled with enough lubricating oil, and engaging between the gear shaft and the toothed baris made to be sufficiently lubricated.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a gear shaft of an automobile steering gear. Background technique [0002] At present, after the rack and pinion steering gear of some automobiles has been used for a certain number of years, the steering gear will appear abnormal noise and sticking. [0003] Research and investigation found that the main reason is that in the process of long-term use, the lubrication effect in the steering gear decreases with time, resulting in poor lubrication effect between the pinion shaft and the rack, and then the pinion shaft and the rack are in transmission. There are abnormal noises and sticking. Contents of the invention [0004] In view of the above-mentioned technical problems, the present invention aims to provide a gear shaft of an automobile steering gear with a good lubricating effect. In order to solve the above-mentioned technical problems, the embodiments of the pre...
