The invention belongs to the technical field of motorcycle rear fork arm suspensions, and particularly relates to a motorcycle rear fork arm variable stiffness decoupling suspension and an adjusting method.The motorcycle rear fork arm variable stiffness decoupling suspension comprises a rear rocker hinged to a motorcycle, and a left force transmission crankshaft and a right force transmission crankshaft are hinged to the two sides of the middle of the motorcycle correspondingly; a crankshaft clutch is arranged between the left force transmission crankshaft and the right force transmission crankshaft, a rocker arm connecting rod is hinged to the front side end of the rear rocker arm, the other end of the rocker arm connecting rod is hinged to the right force transmission crankshaft, and a magnetorheological damper is further connected between the right force transmission crankshaft and the frame. A spiral spring is further connected between the left force transmission crankshaft and the frame, and a torsion bar cushioning structure is further hinged to the side, away from the rear rocker arm, of the right force transmission crankshaft, so that real-time switching of rear fork arm suspension characteristics of the motorcycle under different working condition characteristics can be achieved, and the variable stiffness characteristic of the rear fork arm suspension of the motorcycle is achieved; and the operation stability and smoothness of the motorcycle are improved.

    本发明属于摩托车后叉臂悬架技术领域,具体涉及一种摩托车后叉臂变刚度解耦悬架及调节方法,包括铰接摩托车上的后摇臂,所述摩托车中部两侧分别铰接连接有左传力曲轴、右传力曲轴,所述左传力曲轴与右传力曲轴之间具有曲轴离合器,所述后摇臂前侧端铰接连接有摇臂连杆,所述摇臂连杆另一端与右传力曲轴铰接连接,所述右传力曲轴与车架之间还连接有磁流变阻尼器,所述左传力曲轴与车架之间还连接有螺旋弹簧,所述右传力曲轴上背离后摇臂一侧还铰接有扭杆缓震结构,能够实现摩托车在不同工况特性下的后叉臂悬挂特性的实时切换,实现摩托车后叉臂悬架变刚度特性,改善摩托车的操纵稳定性与平顺性。
