How to adjust the pawl hub

The present invention is an operation method for adjusting the pawl-type hub, especially the technology applied to the bicycle field. The convenience of passengers is an invention with excellent practicality.

Bicycles are one of the favorite means of transportation for many people today. They not only have zero pollution, but also achieve the advantage of strengthening their bodies. Therefore, more and more people will ride bicycles to browse and stroll around during leisure and holidays. However, the terrain is ups and downs. It is a natural scene in many places, so the most difficult part for the rider is this. The height difference of the terrain will make the rider’s physical strength increase completely, so today’s bicycles are all There are basic shifting accessories, which are commonly known as rear shifting, front shifting, etc. in this field. The rider can adjust the shifting according to the environment in which he is riding. If the terrain is relatively flat, the rider can You can feel whether the force you are stepping on is light or not. If you are light enough to step forward, you can maintain this speed. If you encounter high undulating terrain such as climbing, the rider must use the control of the speed change accessories and ride it. It is adjusted by the moment to facilitate climbing with less effort, but there is a big problem with the gear shifting achieved by this method. The rider must be in the most laborious state at the beginning when riding a bicycle to climb the slope, and must The desired gear can be finally reached after constant shifting of gears. During this period, the chain is very easy to be unable to accurately engage with the chainring, causing the problem of chain drop, and even the axis between the chain and the chainring. It is bitten to death, resulting in damage to the chain and chainring, and the entire bicycle must be repaired.

In addition, there is another problem that the speed change adjustment cannot be performed in the non-riding state. Generally, the so-called speed change adjustment is that when the rider is riding, the rider can downshift and upshift the gears in sequence through the switching of the transmission device. The fit of the chainring can slowly jump the teeth according to the configuration of the chainring, but when not riding, the chainring will not rotate at all, so that the chain cannot engage with the desired chainring at all. Therefore, the general shifting method is not suitable for climbing, and the relevant industry must improve it again to meet the needs of the public.

In view of the above situation, the inventor has devoted a lot of time to research related knowledge, compared the pros and cons, conducted research and development of related products, and went through many experiments and tests, and finally launched a "Adjusting Pawl Hub". "Operation method" to improve the above deficiencies to meet the needs of the public.

The main purpose of the present invention is to provide the bicycle with better energy saving when climbing a slope, so the speed change adjustment can be performed before climbing the slope, and the speed change adjustment can be adjusted at rest and neutral, so that the rider can Climbing first preparation is conducive to fast and convenient climbing riding. Its improvement is that ordinary bicycles can only be adjusted at the moment of climbing, which causes the chain to fall off easily. It is not possible to adjust and complete the first time before climbing. To this end, the present inventor strives to achieve the purpose and effect of the aforementioned invention. The present invention is an operation method for adjusting a pawl-type hub, the steps of which include: a turning step: a rider triggers a control element located at the front of a bicycle. A control member, and a plurality of pawls in a ratchet cylinder installed at one end of a hub is assembled with an elastic bundle, and the control member drives the elastic bundle to tighten inward and press against each pawl; the assembly is disengaged Step: Each pawl is restrained in each missing hole at one end of the ratchet tube by the tightening of the elastic binding member, and each pawl is limited in each missing hole and releases the engagement with a ring tooth at one end of the hub, so that the ratchet tube and An idling state is formed between the hubs; gear selection steps: toggle one of a speed change assembly located at the front of the bicycle to shift to the required gear, then drive a drive handle group of the bicycle to rotate, so that a chain The gear can be jumped to the selected gear; and the step of resetting the engagement: after confirming that the chain jumping is completed, the control member is triggered again, so as to release the pressing restriction of the elastic tie on each pawl, and allow each pawl to interact with the ring teeth. It forms an engaged state, so that the rider can shift the gears in a static state without climbing, which is convenient for the first time to achieve the effect of saving effort.

According to the above description, it can be clearly understood that when the bicycle is stationary, the rider can first use the control member to control the elastic binding member located in the ratchet cylinder to tighten the pawls, so that the pawls and the ring teeth of the hub are separated from each other. Tooth state, at this time, the ratchet cylinder and the hub form an idling state, and then control the speed change assembly to change gears, and then operate the drive handle group to rotate to adjust the position of the chain, and finally operate the control member again to release the tightening restriction on the elastic bundle. , so that the pawls and the ring teeth form an engaged state, so that the rider can directly adjust the appropriate gear in the state of preparing for climbing, and reduce the difficulty of shifting after climbing and riding, and will The tooth loss happens. Therefore, the present invention can be regarded as a very practical and progressive invention, which is worthy of vigorous promotion by the industry and publicity to the public.
