The invention discloses an electric tricycle rear axle double-swing-arm suspension mechanism. The mechanism comprises a rear axle frame and two swing arms symmetrically arranged on two sides of the rear axle frame, wherein rear wheels are installed on the two swing arms respectively, a step shaft is arranged on the rear axle frame, each swing arm is rotatably arranged on the step shaft in a sleeving manner, a rotating mechanism is mounted between the rear axle frame and the two swing arms, when the electric tricycle turns, the rotating mechanism enables the two swing arms to deflect relative to the rear axle frame, one swing arm moves upwards around the step shaft relative to the rear axle frame, and the other swing arm moves downwards around the step shaft relative to the rear axle frame.The mechanism is advantaged in that the two swing arms can deflect up and down relative to the rear axle frame under the action of the rotating mechanism, so shafts of the two rear wheels are completely parallel, three wheels of the electric tricycle are always in contact with the ground, the total ground contact area of tires is increased, and stable, comfortable and safe driving experience is provided.

    本发明公开了一种三轮电动车后桥双摆臂悬挂机构,包括后桥桥架、对称设置在后桥桥架两侧的两个摆动臂,两个摆动臂上分别安装有后车轮;后桥桥架上设有台阶轴,各摆动臂可旋转地套设于所述台阶轴上;后桥桥架与两个所述摆动臂之间安装有旋转机构,当三轮电动车转弯时,旋转机构使两个所述摆动臂相对于所述后桥桥架偏摆,其中一个所述摆动臂相对于所述后桥桥架绕所述台阶轴向上运动,另一个所述摆动臂相对于所述后桥桥架绕所述台阶轴向下运动。本发明两个摆动臂可在旋转机构的作用下相对于后桥桥架上下偏摆,从而保证两个后车轮的轴完全平行,保证电动三轮车的三个车轮始终接触地面,增加了轮胎的接地总面积,提供平稳、舒适、安全的驾乘体验。
