The invention provides a bicycle with self-rotating folding wheels, which comprises a wheel rim section, a wheel rim connecting device, a double-shear-fork support, a front axle device, a rear axle device and a floating center shaft device. The wheel rim sections are connected into a closed wheel component through the wheel rim connecting devices, the wheel rim connecting devices at the two ends of the wheel rim sections are hinged to the double-shear-fork support, and the double-shear-fork support is movably connected with the front axle device and the rear axle device through support bases respectively. The rear axle device drives the floating rear cross beam to be connected with the floating middle axle device through the support base. By utilizing the action of ground friction torque, the bicycle can be pushed forward by holding the brake handle, the wheel rim can be quickly unfolded and automatically locked, the bicycle can be pushed backward, and the wheel rim can be quickly folded, which is very convenient. The bicycle with self-rotating folding wheels has the advantages that the requirements on the running speed and stability of the large wheel are met, and the carrying and storage space after the folding of the bicycle is reduced. The wheels and the frame do not need to be stored separately, and the tire is not afraid of being punctured and is worthy of vigorous popularization.

    自转折叠轮自行车包括轮圈段、轮圈连接装置、双剪刀叉支架、前车轴装置、后车轴装置和浮动中轴装置;所述的轮圈段通过轮圈连接装置连接成封闭的车轮构件,所述的轮圈段两端的轮圈连接装置与双剪刀叉支架铰接相连,所述的双剪刀叉支架通过支架座分别与前车轴装置、后车轴装置活动连接;所述的后车轴装置通过支架座带动浮动后横梁与浮动中轴装置连接。利用地面摩擦力矩作用,可实现手握闸把前推自行车,轮圈快速展开并自动锁紧,后推自行车,轮圈快速折叠,特别方便。自转折叠轮自行车在满足大轮子行驶速度性和稳定性的同时,又缩小了折叠后的携带存放空间。轮胎和车架不用分开存放,且有不怕扎胎等特点,值得大力推广。
