Self Complementary Automobile Steering Mechanism

Abstract

The invention discloses a self-complementing automobile steering mechanism, which comprises a rotating shaft and a shaft sleeve. A bushing is arranged between the axial rear end of the rotating shaft inside the shaft sleeve and the shaft sleeve. The rotating shaft is located outside the shaft sleeve. The axial front end of the bushing is connected with a driving mechanism that drives it to swing. The inner ring surface of the bush is composed of an inner conical surface that is narrow inside and wide outside and an arc surface that bows radially inward. The inner tapered surface is correspondingly located at the axial rear end, the arc-shaped surface is correspondingly located at the axial front end, and the axial rear end of the rotating shaft is correspondingly provided with a tapered part, and the arc part fitted with the arc surface, the axial rear end of the bush is equipped with a push mechanism that can push the bush to slide axially forward to realize wear compensation, and the push mechanism includes There are bushings, springs, and rear covers. By adopting the above structure, the service life of the steering mechanism of the automobile can be greatly extended.

Description

technical field [0001] The invention relates to an automobile steering mechanism. Background technique [0002] At present, the automobile steering mechanism mainly includes a rotating shaft and a shaft sleeve. A bushing is arranged between the axial rear end of the rotating shaft located in the shaft sleeve and the shaft sleeve. The axial front end of the rotating shaft located outside the shaft sleeve is connected with a drive Its oscillating drive mechanism is mainly driven by the driver turning the steering wheel and through some transmission devices. Since the rotating shaft swings for a long time under the drive of the above-mentioned driving mechanism, the wear between the rotating shaft and the bush will occur during use. Due to the wear and tear, the direction of the vehicle will vibrate and deviate during driving, and because the bushes in the steering mechanism of the existing automobile cannot automatically compensate for the wear gap after wear, the bushings hav...

[0002] At present, the automobile steering mechanism mainly includes a rotating shaft and a shaft sleeve. A bushing is arranged between the axial rear end of the rotating shaft located in the shaft sleeve and the shaft sleeve. The axial front end of the rotating shaft located outside the shaft sleeve is connected with a drive Its oscillating drive mechanism is mainly driven by the driver turning the steering wheel and through some transmission devices. Since the rotating shaft swings for a long time under the drive of the above-mentioned driving mechanism, the wear between the rotating shaft and the bush will occur during use. Due to the wear and tear, the direction of the vehicle will vibrate and deviate during the driving process, and because the bushes in the steering mechanism of the existing automobile cannot automatically compensate for the wear gap after wear, the bushings have a short service life and are frequently replaced.
