Steering-by-wire system applied to formula car

The steering-by-wire system applied to the formula car comprises a steering gear, a steering rod and a steering machine, the first end of the steering gear is connected with a detachable steering wheel, and the second end of the steering gear is connected with a first universal joint assembly; the first end of the steering rod is coupled to the first universal joint assembly, and the second end of the steering rod is coupled to the second universal joint assembly. The sleeve assembly and the spline assembly are additionally arranged in the steering-by-wire system, the steering-by-wire system is accurately positioned and firmly installed on the formula car, a steering gear and a steering wheel are concentric, the steering process is optimized, and the steering process is smoother and more accurate. The tight wrapping performance of the sleeve assembly and the spline assembly obviously enhances the stress stability of the steering system, and it is ensured that the steering system can bear all torques transmitt
