The invention relates to a rear wheel steering mechanism and a bicycle with the same. The rear wheel steering mechanism comprises a frame, a rear fork, a steering control handle piece, a handle connecting piece, a rear fork connecting piece and a steering pull rod, wherein the rear fork comprises a rear fork shaft and a rear fork main body part, the steering control handle piece is provided with asteering shaft and a steering handle, in the steering process, a connecting point (A) of the steering pull rod and the handle connecting piece rotates around the steering shaft of the steering control handle piece, a rotation radius is R1, in the steering process, a connecting point (B) of the steering pull rod and the rear fork connecting piece rotates around the rear fork shaft, and a rotationradius is R2. The rear wheel steering mechanism is advantaged in that when the vehicle goes straight, a connecting line of the connecting point (A) and the connecting point (B) is tangent to a circlewith the rotating radius of R1 and a circle with the rotating radius of R2 at the same time, and by means of the structure, left-turning direction control and right-turning direction control of the vehicle are not differentiated, so steering is easier to master.

    本发明涉及一种后轮转向机构及带有该机构的自行车,所述后轮转向机构包括:车架、后叉、转向控制把手件、把手连接件、后叉连接件及转向拉杆,所述后叉包括后叉轴及后叉主体部,所述转向控制把手件设有转向轴及转向把手,转向过程中转向拉杆与把手连接件的连接点(A)绕转向控制把手件的转向轴旋转,其旋转半径为R1,转向过程中转向拉杆与后叉连接件的连接点(B)绕后叉轴旋转,其旋转半径为R2,车辆直行时,连接点(A)与连接点(B)的连线与旋转半径为R1的圆及旋转半径为R2的圆同时相切,这样的结构使得车辆的向左转向控制及向右转向控制实现无差异化,进而使转向更容易掌控。
