This paper is based on some basic design parameters of the target vehicle to complete the design requirements of the rack and pinion steering gear. Firstly, a large number of data are collected to make a basic understanding of the basic function, structure and working performance of the rack and pinion steering gear. Based on the investigation and analysis of the development of the existing steering gear types in the world, this paper studies how to meet the design requirements with the lowest cost and up to standard performance. Through the comparison of the steering gear types, calculation of the original parameter formula, material selection and final verification, the steering gear design is completed. According to the design structure, the assembly drawing and some important parts drawing of the steering gear are completed The unreasonable data in the rack and pinion steering gear is corrected by combining drawing and calculation data, so that when the target vehicle is turning, all wheels should rotate around the instantaneous steering center; the structure of the steering gear is reasonable, the strength of parts meets the use requirements; the steering transmission ratio is reasonable, the steering is sensitive, the minimum turning diameter is small, and the operation is light; the reverse force transmitted by the steering wheel to the steering wheel should be It should be as small as possible; the steering wheel rotation direction should be consistent with the change of vehicle driving direction, so as to meet the design requirements of low cost, good performance and the target vehicle model.<br>
