Embodiment Construction

[0086] In order to clearly express the embodiments of the technical solutions of the present invention, the following descriptions will be described in conjunction with figure numbers and component numbers, and examples will be made with figures, quantities and dimensions of the embodiments, which does not mean that the scope of rights is limited thereto.

[0087] See figure 1 , image 3 , Figure 4 A, It can be seen that the present invention is of a different design from commercially available bicycles; see Figure 18 , 20 , this is the chain transmission speed-changing mode of present bicycle, and chain is made up of chain link, and chain link composition comprises chain pin 25-1 and chain ring bushing 25-2 and 25-3 and chain plate 25-4 again, when every time When riding a bicycle, after the rider steps on the pedals, the power is transmitted to the rear wheel through the pedal wheel through the chain, and any two adjacent chain links pass through the outer pitch circle...

Abstract

A speed change system applied to a bicycle uses a transmission shaft for transmission, can achieve an automatic speed change function during riding, and meanwhile solves the problems that a chain falls off during riding and friction force is large during transmission. A centrifugal force principle is utilized, a centrifugal force driving speed change combination device is arranged on a rear cone pulley speed change fluted disc, a centrifugal rotating frame is linked to drive a centrifugal hammer, rotating throwing kinetic energy is converted into linear movement, a speed change deflector rod in a transmission shaft provides thrust according to the vehicle speed, and the gears of pedal middle shaft speed change and rear wheel speed change are changed; and a rider does not need to distract to operate a manual gear shift lever any more, the gears are pushed through a deflector rod in the centrifugal machine device according to the actual speed relative to the road, and then the suitable gears can be applied to full-automatic gear shifting in the starting or climbing stage and the acceleration and high-speed stage, and the rider can easily and pleasantly face various road conditions during riding. In this way, a user can focus on road condition changes during riding, and can enjoy each riding process more safely.

Description

technical field [0001] The invention relates to the application technology of manual and automatic speed change of a bicycle. Background technique [0002] It is known that the bicycles currently on the market generally use chains to transmit the power of the pedal wheels to the rear wheels to push the bicycle forward, and rely on the gear ratio between the pedal wheels and the rear wheels to achieve labor-saving and high-speed gear changes , the method of shifting gears is to change the position of the derailleur on the rear wheel side, so that the chain on the derailleur is shifted to the crankshaft of the adjacent gear shifting gear to realize the shifting, so the shifting of gears in one trip is possible It takes more than dozens to hundreds of times to adapt to various road conditions, such as road traffic lights, uphill and downhill, various obstacles of cars or pedestrians, etc., may need to restart or accelerate, high speed, brake, and repeat this cycle non-stop . ...
