Problems solved by technology

The structure of the rear axle internal variable transmission is relatively complicated, and it is rarely used
Commonly used chain-driven external transmissions on the center shaft and rear shaft, because the driving and driven sprockets are not on the same plane most of the time when they are working, chain jamming and chain dropping are prone to occur, and two shift levers are required to complete the gear shift through combined operation , there are disadvantages such as complex shift adjustment mechanism, many parts, many sprockets, manual step adjustment, etc.

Abstract

A continuously variable bicycle Includes a frame, front wheels, rear wheels, a chain and a transmission arranged on the rear wheels; the rear wheel includes a rear hub and a rear axle disposed on therear hub; the transmission device comprises a transmission wheel disk arranged on the rear wheel axle and rotating synchronously with the rear wheel axle, a shift link rotatably mounted on a shift wheel, a driven sprocket rotatably disposed on the transmission link and engaged with the chain and a transmission control mechanism for controlling rotation of the transmission link to adjust a distancebetween the driven sprocket and the rear wheel shaft; a plurality of the transmission link are arranged and all the transmission links being uniformly distributed in the circumferential direction onthe outer side of the rear wheel shaft. The continuously variable speed bicycle of the invention can realize continuously variable speed, and the speed change operation is simple.

Description

technical field [0001] The invention belongs to the technical field of bicycles, in particular, the invention relates to a continuously variable speed bicycle. Background technique [0002] The speed changer that bicycle uses at present has rear axle internal speed changer and intermediate shaft, rear axle chain drive type external speed changer. The structure of the rear-axle internal variable transmission is relatively complicated, and it is rarely used. Commonly used chain-driven external transmissions on the center shaft and rear shaft, because the driving and driven sprockets are not on the same plane most of the time when they are working, chain jamming and chain dropping are prone to occur, and two shift levers are required to complete the gear shift through combined operation , There are disadvantages such as complex shift adjustment mechanism, many parts, many sprockets, and manual step adjustment is required. Contents of the invention [0003] The present inven...
