Problems solved by technology

Connecting the dust cover with the air pipe will cause a series of troubles due to the addition of extra parts outside the rack and the problems of the air pipe itself, which will bring instability to the use of the steering gear; and the processing equipment for deep holes is often very expensive, and The processing efficiency is low, and the technical ability of personnel is high, which increases the production cost of the product

Abstract

A steering gear rack comprises a shell; a rack is located in the shell; threaded holes are formed in the two ends of the shell. The steering gear rack is characterized in that a middle through hole isformed in the shell and located below the rack; open grooves are formed in the two sides of the threaded holes, and the open grooves communicate with the middle through hole. The middle through holeis formed in the rack shell and the open grooves communicating with the middle through hole are formed in the two sides of the shell, so that ventilation of dustproof covers at the two ends can be achieved through the middle through hole and the open grooves; the structure is simple and reliable, the ventilation effect is good, and maintenance is convenient.

Description

Technical field [0001] The invention relates to the technical field of auto parts, in particular to a steering gear rack. Background technique [0002] The steering gear is a mechanical device with manned and unmanned driving and a power source to make it randomly change the running route and direction during operation. The rack and pinion steering gear is the most common type of steering gear. Its basic structure is a pair of pinions and racks that mesh with each other. When the steering shaft drives the pinion to rotate, the rack moves linearly. Sometimes, the tie rod is directly driven by the rack to turn the steering wheel. Therefore, this is the simplest type of steering gear. The advantages of the rack and pinion steering gear are simple structure, low cost, sensitive steering, small size, and can directly drive the tie rod, so it is widely used in automobiles. [0003] The steering gear rack is an important component of the rack and pinion steering gear, and the dust cov...
