This article is accomplished rack and pinion steering gear according to some basic design parameters of the target vehicle design requirements. First, we gather a lot of information to the essential role of rack and pinion steering, structure and performance as a basic understanding. The world's existing types of steering the development of research and analysis conducted to examine how the design meets the design requirements at the lowest cost, the performance standards, and by comparing the types of steering, the original formula parameters, material selection and final check to complete the design of diverter according to some important parts and draw the structure to complete the design of FIG diverter assembly drawing, in conjunction with the correction data is calculated and plotted in FIG rack and pinion steering gear unreasonable data so that it includes a target vehicle turning when running, all the wheels should turn about an instantaneous center of rotation; reasonable diverter structure, strength of the parts requirements; reasonable steering ratio, steering sensitivity, small minimum turning diameter, control light; a steering wheel transmitted to the steering wheel to make recoil It may be small; turning the steering wheel to change direction with the direction of travel consistent with design requirements, to achieve low cost, good performance and meet the target vehicle design.

This paper is based on some basic design parameters of the target model to complete the design requirements of the gear rack steering. First of all, a large amount of data is collected to make a basic understanding of the basic function, structure and working performance of the gear rack steering. To investigate and analyze the development of the existing steering type in the world, to study how the design meets the design requirements under the condition of lowest cost and performance standard, through the comparison of the steering type, the calculation of the original parameter formula, the material selection and final verification to complete the design of the steering gear, According to the assembly diagram of the design structure to complete the steering gear and the drawing of some important parts, combined with the drawing drawing and calculation data to correct the unreasonable data in the gear rack steering, so that it has the target model turning, all wheels should rotate around the momentary steering center; The steering drive ratio is reasonable, the steering is sensitive, the minimum turning diameter is small, the maneuvering light is light, the reverse force of the steering wheel to the steering wheel should be as small as possible, and the steering wheel rotation direction is consistent with the change of the direction of the car, so that the design of the low cost, good performance and conforms to the target model.

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.
