Description

Rack and pinion steering gear

Technical Field

The utility model relates to the field of machinary, especially, relate to a rack and pinion steering gear.

Background

The rack and pinion steering structure consists of a steering gear integrated with the steering shaft and a rack often integrated with the tie rod. The basic structure is a pair of pinion and rack gears which mesh with each other. When the steering shaft drives the pinion to rotate, the rack makes linear motion. Sometimes, the steering wheel can be steered by directly driving the tie rod by the rack. The pinion of the steering gear is arranged at the lower end of a steering main shaft and is meshed with a steering rack. When the steering wheel is rotated, the pinion in the steering gear rotates, and the rack in the steering gear is driven to move towards the rotating direction of the steering wheel. The action of the steering rack is transmitted to the knuckle arm through the steering rack end and the tie rod end, thereby rotating the wheels
