The invention discloses an electro-tricycle rear wheel suspension device, and relates to rear wheel suspension, the electro-tricycle rear wheel suspension device comprises a wheel axle frame arranged relative to a main keel frame in a mirroring mode, the wheel axle frame comprises a main shaft rod, T-shaped rotating parts are rotationally arranged at the two ends of the main shaft rod respectively, and two supporting legs of each T-shaped rotating part are universally connected with curved bars respectively; and the four curved bars are respectively and universally connected to the main keel frame. According to the rear wheel suspension device of the electro-tricycle, the wheel axle frame can swing up and down relative to the main keel frame in the vertical direction through the curved bar, damping is provided for upward swing of the wheel axle frame in cooperation with the damping mechanism, the whole suspension structure is optimized on the basis that whole rear wheel suspension is simplified, the damping mechanism provides damping for upward swing of the wheel axle frame, and therefore the damping effect is improved. By means of the structure, the damping effect of the damping mechanism can be improved to the maximum degree, and therefore the damping effect of rear wheel suspension is optimal on the basis that the cost is controlled.

    本发明公开了一种电动三轮车后轮悬挂装置,涉及后轮悬挂,包括关于主龙骨架镜像布置的车轮轴架,所述车轮轴架包括主轴杆,所述主轴杆两端分别转动设置有T型旋转件,所述T型旋转件的两个支脚分别万向连接有曲杆,四个所述曲杆分别万向连接于所述主龙骨架上。该发明提供的电动三轮车后轮悬挂装置,利用曲杆使得车轮轴架相对主龙骨架可以关于竖向方向上下摆动,在配合减震机构对车轮轴架上摆提供阻尼,在简化整个后轮悬挂的基础上,优化整个悬挂结构,减震机构对车轮轴架上摆提供阻尼,通过结构可以最大化的提升减震机构的减震效果,从而实现在控制成本的基础上,使得后轮悬挂的避震效果达到最优。
