Abstract

The invention aims to provide a bicycle automatic speed-change device. Under the effect of centrifugal force, a heavy hammer on a rear axle of the bicycle can move a gear tower through the joint effect of an inclined face body and a spring, and a set of gears with the diameter being from large to small on the gear tower is engaged with a gear on a transmission shaft through different gears, and thus automatic speed change is achieved.

Description

[0001] This application is a divisional application of an invention patent application with application number: 2015109983417, invention name: an automatic transmission device for bicycles, and application date: December 23, 2015. technical field [0002] 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 [0003] The current variable speed bicycle gear shift needs to be manually operated, which is cumbersome. Contents of the invention [0004] In order to overcome the deficiencies of the existing speed-changing bicycle speed-changing technology, the invention provides an automatic bicycle speed-changing device. [0005] 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 rota...
