The invention discloses a rear wheel supporting structure of a tricycle, comprising a tricycle frame and wheel seats and further comprising a transverse shaft, support arms, a fixed seat, a swing armand damping arms, wherein the transverse shaft is fixed to the frame; the left and right support arms are movably connected to the transverse shaft and the left and right rear wheel seats respectively; the fixed seat is fixedly connected to the frame, and the middle part of the swing arm is movably connected to the fixed seat through a swing shaft; and the left and right damping arms are movably connected to the middle parts of the left and right support arms respectively. The left rear wheel and the right rear wheel are supported at the same time through the transverse shaft, the support arms, the fixed seat, the swing arm and the damping arms; the left wheel and the right wheel can adaptively move up and down according to driving requirements and road conditions in the driving process; meanwhile, the swing arm swings along with the driving conditions so as to further coordinate movement of the rear wheels, such that comfort of passengers is improved. and the movement of the swing armcan be limited through a swing locking device according to the use condition, so that the follow-up performance of the tricycle in the running process is improved. In addition, during parking, the swing arm can be locked to provide effective support for the tricycle.

    一种三轮车的后轮支撑结构,包括车架和车轮座,还包括:横轴、支撑臂、固定座、摆臂和减震臂;横轴与车架相固定,左、右支撑臂分别与横轴和左、右后轮座活动连接,固定座与车架固定连接,摆臂的中部通过摆动轴与固定座活动连接;左、右减震臂分别与左、右支撑臂的中部活动连接。通过横轴、支撑臂、固定座、摆臂和减震臂同时支撑左、右两个后轮,在行驶过程中左右车轮能够根据行驶需要和路面状况进行适应性上下活动,同时摆臂随行驶状况发生摆动,以进一步协调后车轮的运动,提高乘坐者的舒适度。还可以根据使用状况,通过摆动锁止装置限定摆臂的运动,进而提高三轮车行驶中的随动性能。另外,停车时可以锁定摆臂来对车辆提供有效的支撑。
