Problems solved by technology

However, there are many factors in the process of shifting the chain that affect the shifting effect. Sometimes the shifting cannot be shifted to the preset gear, and the shifting process is stuck. Frequent adjustments are required, and the effect of continuously variable speed cannot be obtained.
Even if some people are now researching various gear set transmissions, but it involves multi-stage transmission, the transmission efficiency will be reduced, and it is not advisable to use it as a human-powered bicycle.

Embodiment 1

[0030] 1. The switch (14) of the oil circuit control system is pressed, and the switch is in the open state. The rigid whole (such as Figure 5 shown), driven by the driving spring (13) as image 3 At this time, the present invention adopts the method of "changing the distance between the axis of the bicycle pedal axis and the axis of the central axis of the bicycle" to achieve speed change. In the high-speed gear, the oil circuit control system switch (free bounce) switch is in the off state, the rigidity is locked as a whole, and the bicycle is in the high-speed pedaling state.

[0031] 2. If the bicycle transmission needs to be changed to a low speed, the oil circuit control system switch (14) (pressed), the switch is in the open state, and the bicycle pedal (1) bicycle pedal rod (3) structural member (8) piston linkage rod (9) A rigid whole composed of (such as Figure 5 Shown) the pedaling force compression drive spring (13) by the pin forces the bicycle pedal axle center...

Abstract

The invention relates to a bicycle transmission. A main body part (6) is a main body part fixed on a bicycle center shaft by using a nut; a guide hole (12) and an oil line control system are machined on the main body part (6); bicycle pedals (1), bicycle pedal rods (3), structural parts (8) and piston linking rods (9) form an integral rigid body; the integral rigid body can slide in the guide hole (12) of the main body part (6) through the bicycle pedal rods (3); and the bicycle transmission is characterized in that the speed change is realized by changing distances between the axes of the bicycle pedals and the axis of the bicycle center shaft. The bicycle transmission is advantaged in that a breakthrough is made in the working principle of the traditional bicycle transmission, bicycles can be convenient and fast to ride, the bicycle transmission is flexible and reliable in operation and good social benefits and economic benefits can be created.

Description

Technical field: [0001] The present invention relates to a bicycle, in particular to a bicycle transmission. Background technique: [0002] At present, the well-known bicycle transmission technology is a sprocket set in which the sprockets are stacked into a tower shape. When shifting, the chain is swung by the derailleur and hung on another sprocket to obtain the gear shifting function. However, there are many factors affecting the shifting effect during the shifting of the chain. Sometimes the shifting cannot be shifted to the preset gear, and the shifting process is stuck. Frequent adjustments are required, and the effect of continuously variable speed cannot be obtained. Even if someone studies various gear set transmissions now, it involves multi-stage transmission, and the transmission efficiency is reduced, so it is not advisable as a human-powered bicycle. Invention content: [0003] Purpose of the invention: [0004] In order to overcome the shortcomings and def...
