Separation type high-speed multi-gearshifting transmission

Abstract

The invention discloses a separation type high-speed multi-gearshifting transmission. A transmission disc is arranged on the right side of a right hub, a screw hole is formed in the middle of the transmission disc, the transmission disc is fixed to a connecting sleeve of the right hub in a threaded connection mode, a high-speed tooth groove, an intermediate-speed tooth groove and a low-speed tooth groove are sequentially formed in the right end face of the transmission disc, ball grooves are formed in the circumference of the transmission disc, a driving disc is arranged on the right side of the transmission disc, high-speed teeth, intermediate-speed teeth and low-speed teeth corresponding to the tooth grooves of the transmission disc are sequentially arranged on the left end face of the driving disc, and arc-shaped slopes are arranged on tooth ways of the high-speed teeth, tooth ways of the intermediate-speed teeth and tooth ways of the low-speed teeth. A middle shaft sleeve is arranged on the left side of the hub, a middle shaft is arranged in the middle shaft sleeve, and the driving disc is installed on the middle shaft through a bearing. The separation type high-speed multi-gearshifting transmission is simple in structure, convenient to detach, install and maintain, convenient and quick to use and good in effect, and gearshifting speed change can be easily achieved during riding only by backing pedals.

Description

technical field [0001] The invention relates to a driving wheel, specifically a high-speed multi-speed variable speed wheel for a bicycle. Background technique [0002] Most of the bicycles sold on the market are single-gear and single-tooth structures, and the speed of riding is relatively slow. When in a hurry or long-distance driving, the speed of the vehicle cannot be increased, and the needs of consumers cannot be satisfied. Contents of the invention [0003] Therefore people have great demand to the high-speed multi-speed bicycle speed changer, so far, have not found relevant report about the present invention, the inventor has finally developed separate high-speed multi-speed change-speed wheel disc through repeated research tests, thereby The present invention has been accomplished. [0004] The purpose of the present invention is to provide a split-type high-speed multi-speed transmission to increase the use function of the human-powered bicycle, increase the spe...
