The invention belongs to the technical field of vehicles, and discloses an elastic buffer part, a vehicle steering gear and a vehicle steering system. According to the elastic buffering piece, an elastic body comprises first wave-shaped parts and second wave-shaped parts which are alternately distributed, the first wave-shaped parts protrude towards a first direction, the second wave-shaped parts protrude towards a second direction, the first direction is opposite to the second direction, and the first direction and the second direction are both parallel to the axis of the elastic body; the elastic body is set to deform when being subjected to external acting force, and deformation comprises a waveform deformation stage and an excessive deformation stage. The elastic buffering piece is simple in structure and has a good buffering and vibration absorbing effect; according to the vehicle steering gear, the elastic buffering piece is applied, the service life of the shell and the service life of the connecting base are effectively prolonged, the maintenance frequency of the vehicle steering gear is reduced, the phenomenon of vibration transmitted to a steering wheel is reduced, part of noise generated by collision can be absorbed, and the driving comfort of a driver is improved.

    本发明属于车辆技术领域,公开了一种弹性缓冲件、车辆转向器及车辆转向系统。该弹性缓冲件,弹性本体包括交替分布的第一波形部和第二波形部,第一波形部向第一方向凸出,第二波形部向第二方向凸出,第一方向与第二方向相反,且第一方向和第二方向均平行于弹性本体的轴线;弹性本体被设置为受到外部作用力时产生形变,形变包括波形形变阶段和过度形变阶段。该弹性缓冲件,结构简单且具有良好的缓冲吸振效果;该车辆转向器应用上述的弹性缓冲件,有效提高了壳体和连接座的使用寿命,减少了车辆转向器的维修频率,减少了传递至方向盘的振动现象,且能够吸收部分由撞击产生的噪音,提高了驾驶员的驾驶舒适性。
