Abstract

A formula student race car steering system and manufacturing and installing methods thereof are provided. The steering system comprises a steering component, a compressing device, adjustable transverse pull rods and a steering wheel assembly; the steering component includes a steering unit housing, a transverse casing, a gear shaft and a rack; the steering wheel assembly is connected with the steering unit housing through a connection rod component. The manufacturing method includes: performing fitting analysis according to experimental data from race tire officials, and selecting most suitable Ackermann percent; optimally screening out a reasonable steering gradient layout form via MATLAB, and checking steering torque and fitting a Ackermann curve for comparative analysis; using adams tocorrect and manufacture the corresponding steering component, compressing device, adjustable transverse pull rods and steering wheel assembly; locking the steering unit housing to one end of the transverse casing; selecting a suitable gear shaft to rack transmission ratio, and installing the compressing device and the steering wheel assembly; adjusting the length of the adjustable transverse pullrods to finish installation. The formula student race car steering system and the manufacturing and installing methods thereof have the advantages that precision and sensitivity are good, stability and reliability are good, and a limiting function is provided.

Description

technical field [0001] The invention relates to a steering system of a student formula racing car, a manufacturing method and an installation method thereof. Background technique [0002] The steering system of the FSAE (China Student Formula Competition) racing car is the most important bridge connecting the driver and the racing car. The steering system needs to work with the suspension, the wheel and the power source in order to ensure the sensitivity and stability of the steering under various working conditions. precision. The driver controls the steering system by holding the steering wheel according to the actual vehicle conditions and road conditions, so as to realize the driving control of the racing car. At the same time, the angular displacement sensor installed on the steering component obtains a series of signals such as the size of the corner and the acceleration of the corner, and quickly transmits them to the vehicle controller for calculation and execution ...
