Abstract

The invention relates to the technical field of automatic steering, and discloses a steering device support mechanism, which is used for supporting a steering device rank. The steering device support mechanism includes a support seat and a rack guide wheel; the rack guide wheel is arranged in the support seat; two axial ends of the rack guide wheel are rotatably connected to the support seat; the rack guide wheel is of a shrinking waist-shaped structure, wherein the two axial ends of the rack guide wheel gradually recess inward; and an outer surface of the rack guide wheel matches an outer surface of the steering device rack. The steering device support mechanism can reduce mechanical friction and system noise of a steering system, and improve the durability of the steering device, the returnability, operation feeling and drivability of a vehicle, and the NVH performance of the vehicle.

Description

Technical field

[0001] The invention relates to the technical field of automobile steering, in particular to a steering gear support mechanism for reducing mechanical friction and system noise. Background technique

[0002] The rack-and-pinion steering gear is the most common 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 in a straight line. Sometimes, the steering wheel can be steered by directly driving the tie rod by the rack. Therefore, this is the simplest type of steering gear. Its advantages are simple structure, low cost, sensitive steering, and small size. It can directly drive the steering wheel. Tie rod. It is widely used in automobiles.

[0003] When the steering gear rack is moving, because the support mechanism and the rack are in surface contact, large sliding friction needs to be overcome, so that the friction in the system is large, the steering feel ...
