The invention belongs to the technical field of vehicle steering systems, and particularly relates to a self-resetting mechanism of a steering system and a vehicle. The piston divides a hydraulic cavity of the hydraulic cylinder into a first hydraulic cavity and a second hydraulic cavity; the piston rod is fixedly connected with the piston, and the two ends of the piston rod penetrate to the outer sides of the two ends of the hydraulic cylinder; the valve assembly is connected with the first hydraulic cavity and the second hydraulic cavity through pipelines. One of the hydraulic cylinder and the piston rod is connected to a transverse pull rod of the steering system, and the other one of the hydraulic cylinder and the piston rod is connected to a frame or a structure fixed relative to the frame. According to the self-resetting mechanism, the wheels can be automatically reset when a vehicle steering system fails, due to the existence of the valve assembly, the steering angle of the wheels cannot be increased even if the road surface is concave-convex, bumpy and the like, it is ensured that the steering angle of the wheels can finally return to the preset threshold value range and is kept within the preset threshold value range, and the safety of the vehicle is improved. And the safety of the steering system is improved.

    本发明属于车辆转向系统技术领域,具体涉及一种转向系统的自复位机构及车辆,包括:液压缸;活塞,活塞将液压缸的液压腔分隔为第一液压腔和第二液压腔;活塞杆,与活塞固定连接,且活塞杆的两端分别贯穿至液压缸两端的外侧;阀组件,阀组件通过管路分别与所述第一液压腔和第二液压腔连接;所述液压缸和所述活塞杆中的其中一者连接于转向系统的横拉杆,另一者连接于车架或与车架相对固定的结构上。本发明的自复位机构能够在车辆转向系统失效时,使车轮自动回正,而由于阀组件的存在,即使路面存在凹凸、颠簸等情况,车轮也不会增大转向角度,确保车轮转向角最终能够回到预设的阈值范围内,并保持在该预设的阈值范围内,提高了转向系统的安全性。
