[0002] The steering system of a car is a device used to change or maintain the direction of driving or reversing, and to control the driving direction of the car according to the driver's wishes, so the stability of the steering system of the car is very important to the driving safety of the car; the current steering system Usually, the steering gear is used to drive the tie rod. The tie rod is directly connected to the steering knuckle and drives the steering knuckle to drive the steering of the wheels. When the car is driving vigorously or turning under complex road conditions, the ground force on the wheels will be reversed through the steering knuckle. It is applied to the tie rod and acts on the steering gear through the tie rod, so that the tie rod and the steering gear are prone to stress shocks, and it is easy to damage the components of the steering system

Abstract

The invention discloses an automobile steering system which comprises a pull rod, a steering gear driving the pull rod to move and a buffer device arranged between the steering gear and the pull rod.The buffer device comprises a buffer assembly connected between the steering gear and the pull rod and a locking assembly arranged on the buffer assembly and used for locking the buffer function of the buffer assembly. According to the steering system, the acting force of wheels reversely acting on the pull rod and the steering gear can be buffered through the buffer assembly, so that parts of thesteering system are effectively protected and the reliability of the steering system is improved; meanwhile, through cooperation of the buffering assembly and the locking assembly, driving of the automobile under various working conditions is facilitated, accurate steering under the working conditions of good road conditions or high automobile speed is facilitated, and buffering of the reverse acting force under the working conditions of bumpy road conditions and low automobile speed is also facilitated.
