Embodiment 1
[0047] Embodiment 1 A steering system for a Formula Student racing car according to the present invention includes a steering assembly 1 for steering the steering wheel, a pressing device 2 for limiting the steering wheel rotation angle, and an adjustable tie rod for connecting with the frame 3 and a steering wheel assembly 4 for steering, the steering assembly 1 includes a steering gear housing 11, a transverse sleeve 12, a pinion shaft 13 and a rack 14, and the steering gear housing 11 includes two coaxial transverse The interface 111 and a longitudinal interface 112 with internal threads, and the outer ends of the two transverse interfaces 111 are provided with shoulders for installing the transverse casing, and there is a mounting for inserting the compression device between the two transverse interfaces 111 Through holes 113, wherein the installation through holes 113 communicate with the inner cavity of the longitudinal interface 112; the shoulders of the steering gear ho...
Embodiment 2
[0052] Embodiment 2 A method of manufacturing a steering system for a Formula Student racing car according to Embodiment 1, comprising the following steps:
[0053] (1) According to the fitting analysis of the official test data of racing tires, and considering the tire stiffness, suspension stiffness, the effect of empty sleeve, body roll stiffness and the working conditions of the competition, after obtaining the required specific state, it is simulated and optimized by MATLAB program, and the selected Optimal Ackerman percentage;
[0054] (2) After obtaining a reasonable Ackerman percentage, optimize it through the MATLAB program, screen out a reasonable steering trapezoidal layout, and check the steering torque and fit the Ackerman curve for comparative analysis;
[0055] (3) Use Adams software to conduct kinematics analysis jointly with the suspension and the wheel edge, verify the reasonableness of the trapezoidal layout in the vehicle simulation, and correct the tire po...
Embodiment 3
[0062] Embodiment 3 According to Embodiment 1, a method for manufacturing a steering system of a Formula Student racing car according to the present invention includes the following steps:
[0063] 1) The lateral interface of the steering gear casing is clamped with one end of the horizontal casing on the same side through the shoulder at the end, and the two horizontal casings are kept coaxial with the horizontal interface, and the other end of the horizontal casing passes through the corresponding The support is installed at the front of the inner cavity of the frame;
[0064] 2) Select the appropriate transmission ratio of gear shaft and rack, and then insert the rack into the steering gear housing and the two transverse bushings. The bit through hole penetrates and then touches the platform on the back of the rack, and the steering angle is limited by adjusting the compression degree of the compression device;
[0065] 3) Put the mounting part of the gear shaft through th...
