[0002] Two rollers pressed against each other transmit motion and power through the friction between the contact surfaces. Due to its simple structure, easy manufacturing, smooth operation, low noise, overload can slip, can prevent damage to important parts of the equipment, and can continuously and smoothly adjust its transmission ratio, it has a wide range of applications and has become the main component of continuously variable transmission.

[0003] The existing patent (publication number: CN216136645U) proposes a stable rotating fitness bicycle transmission wheel, including parallel abutment rods, parallel support rods are fixedly connected to the surface of the abutment rods, and a brake part is fixedly arranged between the parallel abutment rods, and the fixed shaft is supported by the support rods on the abutment rods, and the installation kit is installed in the middle of the fixed shaft, and the installation kit supports the inner wall of the rotating wheel through the connecting rod, and the rotating wheel is made stronger through the connecting rod. At the same time, a protective layer is slidably installed in the annular groove of the outer wall of the rotating wheel, and is installed on the fixed shaft through the ring sheet inside the protective layer. The protective layer reinforces and limits the rotation of the rotating wheel, thereby improving the stability of the rotating wheel, and at the same time, the sliding rod is pushed by the spring in the sleeve of the brake part, and the brake belt is connected to the outer ring of the rotating wheel through the sliding rod, so that the rotation speed of the rotating wheel can be slowed down, so that the rotating wheel can be stopped quickly.

[0004] The above device improves the stability of the transmission wheel, but cannot provide different resistances for different groups of people, which will lead to a poor user experience. Therefore, we propose a stable rotating fitness bike transmission wheel to solve the above problem. Utility Model Content
