Abstract

The invention aims to disclose an automatic speed changing device of a bicycle. Under the effect of centrifugal force of a heavy punch on a bicycle rear shaft, a gear tower can be moved through the combined action of a slope body and a spring, the gear tower is provided with a set of gears from big to small, and automatic speed changing is achieved through engagement of the different gears and gears on a transmission shaft.

Description

technical field [0001] The invention relates to an automatic speed change device for a bicycle, which can be used to realize automatic speed change while the bicycle is running. technical background [0002] The current variable speed bicycle gear shift needs to be manually operated, which is cumbersome. Contents of the invention [0003] In order to overcome the deficiencies of the existing speed-changing bicycle speed-changing technology, the invention provides an automatic bicycle speed-changing device. [0004] The technical solution adopted by the present invention to solve the technical problem is: the bicycle flywheel and the flywheel connecting gear are connected together, the bicycle flywheel drives the flywheel connecting gear to rotate, and the flywheel connecting gear drives the transmission gear between the rear axle outside the casing and the drive shaft to rotate, and the outside of the casing The transmission gear one between the rear axle and the transmis...
