The invention relates to a rear axle steering system with active steering and aligning functions, which comprises a rear axle assembly and a rear axle assembly, wherein the rear axle assembly comprises an I-shaped beam, and the I-shaped beam is provided with a concave bent section; the steering engine support is arranged above the rear axle assembly in parallel, and a groove is formed in the bottom of the steering engine support. When the steering engine support is installed on the rear axle assembly, the groove and the concave bent section form a plumbing arm arrangement swing space. The steering engine assembly comprises a driving device and a steering plumbing arm device which are arranged on a steering engine support. The steering plumbing arm device is located in the plumbing arm arrangement swing space and connected with a steering engine pull rod. Therefore, during use, the driving device of the steering engine assembly drives the steering knuckle connected with the steering engine pull rod so as to realize steering and aligning functions; the thinking mode that the steering engine is fixed to the vehicle frame is completely separated, the steering engine is fixed to the vehicle axle, connection of the steering engine and the vehicle axle is not affected by deformation of the suspension, steering is easy to control, and the relative steering angle is accurate; the change on the axle is small, and the manufacturing cost is reduced.
本申请涉及一种具备主动转向及回正功能的后桥转向系统,其包括:后桥总成包括工字梁,工字梁具有凹陷弯曲段;转向机支架平行设置在后桥总成上方,并且其底部形成有一凹槽;当转向机支架安装在后桥总成上时,凹槽与凹陷弯曲段形成垂臂布置摆动空间;转向机总成包括设置在转向机支架上的驱动装置和转向垂臂装置;转向垂臂装置位于垂臂布置摆动空间内,并连接有转向机拉杆。从而在使用时转向机总成的驱动装置带动与转向机拉杆连接的转向节,以实现转向及回正功能;完全脱离了将转向机固定在车架上的思维模式,转向机固定在车桥上,转向机与车桥的连接不受悬架变形的影响,易于控制转向,相对转向角度精准;对车桥改动小,减少制造成本。
