The invention relates to a motorcycle and a rear suspension four-connecting-rod mechanism thereof. The rear suspension four-connecting-rod mechanism of the motorcycle comprises a pull rod, a swing armlever and a shock absorber; the first end of the pull rod and the first end of the shock absorber are rotationally connected to a frame; the second end of the pull rod and the second end of the shockabsorber are rotationally connected to the two ends of a swing arm lever respectively; the swing arm lever is rotationally connected to a rear bottom fork; and connecting points, used for being rotationally connected with the pull rod, the shock absorber and the rear bottom fork, on the swing arm lever are distributed in a triangular shape. According to the rear suspension four-connecting-rod mechanism of the motorcycle, the stroke of the shock absorber can be increased nonlinearly through the swing arm lever; the rigidity characteristic and damping characteristic of a rear suspension are changed in a nonlinear mode and can be changed along with changes of external impact and vibration, namely the rear suspension becomes soft under weak impact and becomes hard under strong impact, and therefore the comfort of the motorcycle is improved.

    本发明涉及一种摩托车及其后悬挂四连杆机构,该摩托车后悬挂四连杆机构包括拉杆、摆臂杠杆以及减震器,其中,拉杆第一端以及减震器的第一端分别可转动地连接于车架,拉杆的第二端以及减震器的第二端分别可转动地连接于摆臂杠杆的两端,摆臂杠杆可转动地连接于后平叉,摆臂杠杆上用于与拉杆、减震器以及后平叉转动连接的连接点呈三角分布;上述摩托车后悬挂四连杆机构通过摆臂杠杆能够非线性地增加减震器的行程,使后悬挂的刚度特性和阻尼特性呈非线性变化,能够随外部冲击、振动的变化而变化,即在弱冲击下后悬挂变“软”,在强冲击下后悬挂变“硬”,从而提升摩托车的舒适性。
