Rack and pinion steering gear
[Abstract]This topic is the subject of automotive steering rack and pinion steering design. Rack and pinion steering gear design of the core there are two points: First, the rack gear and the reasonable match to meet the correct steering gear ratio and strength requirements; the second is the design of steering gear adjustment mechanism, a reasonable match the stiffness of the spring, to ensure that the starting torque and the steering gear meshing characteristics. Therefore, the subject of the above requirements and factors considered on the basis of research driven by the rotation of the steering wheel rack and pinion steering transmission mechanism of the steering shaft, steering gear through the universal joint drive shaft rotation, shaft and steering rack steering gear meshing, thus contributing to steering rack linear motion, to achieve steering. Simple and compact structure to achieve the steering gear, short axial dimensions, and the number of parts can increase the advantages of less power, enabling the vehicle steering stability and sensitivity. In this article, mainly for the design of the steering rack and pinion steering gear shaft and the Verification, the main method and theory with experience in automotive design parameters and mechanical design of the university curriculum design, and the results meet the strength requirements, safe and reliable.
