Abstract

In order to solve the problem that the rack and pinion steering gear in the prior art easily produces abnormal sound in the use process, the invention provides a rack and pinion steering gear. The rack and pinion steering gear comprises a shell, a rack, a pinion shaft and a positioning ring, wherein the positioning ring is fixed in the shell; a positioning hole is formed in the positioning ring; the rack is arranged in the shell and simultaneously penetrates through the positioning ring; the rack and the positioning hole are in transition fit, so that the rack can move relative to the positioning ring in the axial direction of the shell, and the positioning ring fixes the rack at the periphery of the rack; the pinion shaft is arranged on the shell in a rotatable manner, and the axial direction of the pinion shaft is tilted relative to the axial direction of the shell; and the pinion shaft is meshed with the rack, and the rotating of the pinion shaft drives the rack to move in the axial direction of the shell. The rack and pinion steering gear provided by the invention can effectively reduce metal hitting sound made between the pinion shaft and the rack teeth of the rack when the pinion shaft rotates and is favorable to improving the quality of the whole vehicle.

Description

technical field [0001] The invention relates to a rack and pinion steering gear. Background technique [0002] In the normal driving of a car, turning left, turning right and driving straight are three basic movements. In order to ensure the smooth running of the car, there is a set of mechanisms between the steering wheels of the car to complete the driving of the car. This set of mechanisms that can flexibly change the direction of the car is called the steering system of the car. This set of mechanisms is connected to the steering wheel of the car cab through various rigidities. Controlled by the driver. [0003] The steering gear is an important part of the steering system of the car, and the rack and pinion steering gear is a kind of mechanical steering gear commonly used in the steering system of the car. It also has a direct impact on the quality and driving pleasure of the vehicle. [0004] At present, the mechanical rack and pinion steering gear is prone to abnor...
