The invention provides an auxiliary supporting structure which comprises an outer shell, a steering screw rod and a supporting assembly, the outer shell and the steering screw rod are arranged in the outer shell and rotationally connected with the outer shell, the steering screw rod is provided with a steering nut, the steering nut is in threaded connection with the steering screw rod, the supporting assembly comprises a supporting roller, and the supporting roller is rotationally connected with the outer shell. The supporting roller is provided with a first conical surface, the steering nut is provided with a first attaching surface, and the first conical surface abuts against the first attaching surface and is used for pressing the steering nut on the steering screw. Through the supporting roller, on one hand, sliding friction between the steering nut and the outer shell is changed into rolling friction between the steering nut and the supporting roller, the efficiency of the steering gear is improved, the possibility of abrasion is reduced, and therefore the possibility of leakage and failure of the steering gear is reduced; and on the other hand, pressure is applied to the first attaching face, so that the steering nut can be limited when the first conical face abuts against the first attaching face, and the possibility that the steering nut deviates from the center is reduced.
本申请提供了一种辅助支撑结构,包括外壳体、转向螺杆以及支撑组件,外壳体,转向螺杆设置在外壳体内,并与外壳体转动连接,转向螺杆设置有转向螺母,转向螺母与转向螺杆螺纹连接,支撑组件包括支撑滚轮,支撑滚轮与外壳体转动连接,支撑滚轮设置有第一锥面,转向螺母设置有第一贴面,第一锥面与第一贴面抵接,用于将转向螺母压紧在转向螺杆上。通过支撑滚轮,一方面使得转向螺母与外壳体之间的滑动摩擦变为转向螺母与支撑滚轮之间的滚动摩擦,提升转向器的效率,降低磨损的可能性,从而降低转向器泄露和失效的可能性;另一方面,对第一贴面施加压力,使得第一锥面和第一贴面抵接时能够对转向螺母提供限位效果,减少转向螺母偏离中心的可能性。
