Fitness bicycle with central CVP continuously variable transmission

Abstract

The invention discloses a fitness bicycle with a CVP continuously variable transmission. The bicycle comprises a CVP planetary steel ball continuously variable transmission, a chain wheel, a pedal crank, a transmission chain, a speed regulation handle, a vertical rod, a cushion, a moving flywheel, a bicycle frame and a speed regulation device, and is characterized in that an input end of the CVP planetary steel ball continuously variable transmission is connected with the pedal crank, an output end of the CVP planetary steel ball continuously variable transmission is connected with the chain wheel, a flywheel chain wheel is arranged on the moving flywheel and is in transmission with the chain wheel through a transmission chain, the cushion is installed on the frame and located above the pedal crank, and the speed regulation handle regulates the speed of the CVP planetary steel ball continuously variable transmission through the speed regulation device. The CVP planetary steel ball continuously variable transmission is applied to the fitness bicycle and directly arranged at the pedals, adjustment of different exercise intensities can be achieved without replacing or adding a balanceweight flywheel, operation is easy and convenient, and the exercise experience is good.

Description

technical field [0001] The invention relates to a body-building exercise equipment, in particular to a body-building bicycle with a central CVP continuously variable transmission. Background technique [0002] Although fitness bicycles are similar to ordinary bicycles, they are much different in function and function. Fitness bicycles are mainly used for indoor sports, which overcomes all the shortcomings of outdoor driving, and can exercise the whole body. At present, fitness bicycles use pedals to drive the belt to drive the flywheel. The weight of the flywheel is fixed, and the driving demand is fixed. One machine cannot adapt to different groups of people. To solve this problem, the patent number CN201920849785.8 discloses a multi-adjustable spinning bicycle. By adopting the counterweight studs installed in cooperation to increase or decrease the counterweight, the difficulty of pedaling can be adjusted, which meets the diverse requirements of users. Although it solves ...

Problems solved by technology

At present, fitness bicycles use pedals to drive the belt to drive the flywheel. The weight of the flywheel is fixed, and the driving demand is fixed. One machine cannot adapt to different groups of people.

To solve this problem, the patent number CN201920849785.8 discloses a multi-adjustable spinning bicycle. By adopting the counterweight studs installed in cooperation to increase or decrease the counterweight, the difficulty of pedaling can be adjusted, which meets the diverse requirements of users. Although it solves the problem of using diversity, it needs to perform counterweight operation during use, which is not particularly convenient and convenient to use
