The invention relates to a steering return assisting device, a steering mechanism and a vehicle. The steering return assisting device comprises an outer gear (2) fixedly arranged outside a steering column (1) in a sleeving mode, an inner gear (3) arranged outside the outer gear in a sleeving mode, a shell (4) arranged outside the inner gear in a sleeving mode and an elastic element (5), one end ofthe elastic element is connected with the shell, and the other end of the elastic element is connected with the inner gear. One of the outer gear and the inner gear is provided with fixed gear teeth,and the other one is provided with rotatable gear teeth, so that when the steering column rotates in a first direction, the outer gear and the inner gear are in meshing transmission, and when the steering column rotates in a second direction, the outer gear and the inner gear slide relatively. The steering return assisting device of the mechanical structure is provided, so a good return effect can be achieved even under the condition that steering force is small when the vehicle turns at a low speed, a small angle and the like.
本公开涉及一种转向回正辅助装置、转向机构及车辆,其中的转向回正辅助装置包括固定地套设在转向管柱(1)外的外齿轮(2)、套设在所述外齿轮外的内齿轮(3)、套设在内齿轮外的壳体(4)、以及弹性元件(5),所述弹性元件一端与所述壳体连接,另一端与内齿轮连接。外齿轮和内齿轮中的一者具有固定轮齿,另一者具有可转动的轮齿,以使转向管柱朝第一方向转动时外齿轮与内齿轮啮合传动,朝第二方向转动时外齿轮与内齿轮相对滑动。通过上述技术方案,提供一种机械结构的转向回正辅助装置,使得车辆即使在低速和小角度转弯等转向力较小的情况下,也能产生较好的回正效果。
