The invention provides a continuously variable transmission for bicycles. According to the principle of automotive transmission, the original chain drive of a bicycle is changed into gear drive, and continuously variable speed which the chain drive cannot provide is implemented; a differential is used to reasonably allocate torque, continuously variable speeds of the bicycle is achieved, jumping teeth caused by chain rotation is avoided, high impact of varying speed easily breaks a chain is avoided, and speed varying is unsmooth is avoided. Redundant power can be used to generate electricity, and a generator and a brake device can be conveniently mounted.
Description
technical field [0001] The invention relates to a transmission with a differential, which is a safe, efficient and stable transmission. Background technique [0002] In the existing bicycles, the vast majority of speed changers are chain drives. The chains are exposed and easily pollute clothes. When changing speeds, they often jump, are unstable and easy to tear the chains, causing serious safety accidents. Contents of the invention [0003] The object of the present invention is to provide a safe, efficient and stable continuously variable transmission. [0004] The technical solution adopted by the invention is: through the intervention of the differential, the speed of the bicycle is continuously controlled by continuously controlling the rotation speed of the turntable, which is safe and easy to operate, and has a large speed change range. [0005] The beneficial effect of the present invention is that: the transmission can safely, stably and continuously realize the...
