What are the classifications of automotive steering gears?
1 Answers
Automotive steering gears can be classified into: rack and pinion type, worm and roller type, and recirculating ball type. The rack and pinion steering gear is a common type, whose basic structure consists of a pair of meshing pinion and rack. When the steering shaft drives the pinion to rotate, the rack moves linearly. The worm and roller type steering gear uses the worm as the driving component and the roller as the driven component, typically employed in trucks requiring greater steering force. The recirculating ball type steering gear mainly consists of two parts: the mechanical part and the hydraulic part. The mechanical part includes the housing, side cover, upper cover, lower cover, recirculating ball screw, rack nut, rotary valve spool, and sector gear shaft.
