Turning limiting method for automobile steering gear

Abstract

A turning limiting method for an automobile steering gear relates to the technical field of automobile steering gears, and is characterized in that a turning limiting structural method for the automobile steering gear is modified, a steering nut chamfer is enlarged based on an original structure method to disable the steering nut to contact with a bearing inner ring under any special conditions, a lower limit position of the steering gear is positioned by a steering casing positioning boss and the lower side of the steering nut, an upper limit position of the steering gear is positioned by an end face of an end cover and the upper side of the steering nut, and output size of a swing angle can be limited reliably. The service life of the automobile steering gear is prolonged after the limiting method is modified, running safety of an automobile under any emergency conditions can be guaranteed, possibility of quality claim is greatly reduced, and profits can be guaranteed for enterprises.

Description

technical field [0001] The invention relates to the technical field of an automobile steering gear, in particular to a method for limiting the rotation angle of an automobile steering gear. Background technique [0002] Automobile steering gear assembly is a key security part in automobile operation, and its quality is closely related to human life. Automobile steering gear assembly is required to have a certain output swing angle according to different types of models, and there must be a fixed limit in the automobile steering gear assembly to prevent other accidents from happening. The limit of the output swing angle of the automobile steering gear in the prior art is that the end faces of the bearing inner rings of the upper and lower thrust angular contact ball bearings and the two sides of the steering nut are positioned to limit the output of the swing angle. When an emergency occurs, the steering gear will generate a large impact when it turns, and when it is positio...

AI Technical Summary

Problems solved by technology

In the prior art, the limit of the output swing angle of the automobile steering gear is positioned by the end face of the bearing inner ring of the upper and lower thrust angular contact ball bearings and the two sides of the steering nut to limit the output of the swing angle

When an emergency occurs, the steering gear will generate a large impact when it turns, and when it is positioned with the inner ring of the bearing, it will transmit a large impact force to the bearing, thereby reducing the service life of the bearing. The bearing is damaged, which leads to the failure of the steering gear, which will bring great economic losses and even personal casualties
