Abstract

The invention relates to a rear-wheel guiding chainless bicycle comprising a front wheel and a rear wheel, wherein the rear wheel is smaller than the front wheel, pedals are directly arranged on a front wheel shaft, the front wheel is arranged between a front fork and an inclined frame, the rear wheel is similar to or the same with a wheel of that of the traditional bicycle or is a motor which is an external-rotor motor and has the functions of an electric generator and an electric motor; the rear wheel is arranged in a rear fork, the rear fork is connected with the inclined frame by a connecting block and is in running fit with the connecting block, the upper end of the rear fork is provided with a gear, a supporting rod is used for connecting a bicycle tail frame and the connecting block, the bicycle tail frame is connected to the upper part of the front fork, the motor is connected with a controller arranged in the bicycle tail frame, the controller is connected with a storage battery arranged into the bicycle tail frame, a saddle is arranged at the top end of the front fork, a rudder is connected with a rotary drum arranged on the upper part of the front fork and passes through the front fork, and the tail end of the rudder is connected with an arc-shaped driving piece which is meshed with the gear by teeth, thereby steering is realized. The rear-wheel guiding chainless bicycle has simple structure, is light and reliable and is easy to popularize.

Description

technical field [0001] The invention relates to bicycle technology, in particular to a rear wheel guided chainless bicycle. Background technique [0002] Existing bicycle of all kinds big and small all must have sprocket drive mechanism. The sprocket transmission mechanism can increase the rotational speed of the wheels, and can make the force of the person and the gravity of the whole vehicle (including the gravity of the person) reach a coordinated balance, which meets the requirements of ergonomics. But sprocket drive friction force is big, efficiency is low, chain is easy to damage, chain drop occurs occasionally, and sprocket drive mechanism needs to be lubricated frequently, and lubricating oil often can dirty people's underwear or footgear. Contents of the invention [0003] In order to overcome the above-mentioned defects of the existing bicycles, the present invention designs a rear-wheel guided chainless bicycle, which is light in use and high in reliability. ...
