Description

Speed change shaft force enhancement and stability protection device

This invention is related to a technology of a gearshift shaft force enhancement and stability protection device, especially a gearshift shaft force enhancement and stability protection device that can improve the accuracy of shifting, reduce the torsional wear of the gearshift shaft, increase the stability of the gearshift shaft, and avoid deformation of the gearshift shaft. It can also increase the strength of the torsion spring to avoid the problem of shifting and avoid deformation of the gearshift shaft, so as to improve the stability of the gearshift shaft during shifting.

The gearbox and shift lever of a gear bike can shift to different gears according to different road conditions. Good and stable gear shifting is one of the important factors for the smoothness of riding a gear bike. The gear shaft is a long shaft located in the gearbox, connecting the transmission system between the gearbox and the wheels, and one end of the gear shaft is exposed to the outside without any other parts to support or cover it.

The exposed gear shift shaft is long. When the gears are shifted for a long time, the exposed gear shift shaft is long and the torque is long. Therefore, after a long time of use, it is easy to produce a gap, resulting in instability during gear shifting. When the vehicle falls and turns over, the impact force will be transmitted, causing the gear shift shaft to be distorted and unable to operate. The gear shift fork torsion spring in the gearbox is not strong enough, which is easy to cause gear skipping problems, which will not only affect the riding experience, but also may cause danger.

In addition, some companies on the market will directly install a bearing in the gearshift shaft fixture to increase the stability of the gearshift shaft. Although the bearing can increase stability, when the vehicle turns over, the impact force will cause the bearing to get stuck on the gearshift shaft, causing inconvenience during maintenance, which in turn makes maintenance more complicated and time-consuming.

Therefore, how to create a gearshift shaft force enhancement and stability protection device that can be wrapped around the exposed part of the gearshift lever to improve the stability and accuracy of the gearshift, and prevent the exposed gearshift shaft from being distorted and deformed when the vehicle falls and turns over. The added special torsion spring can prevent the gear from skipping, thereby improving the smooth riding experience, and at the same time improving the safety and convenience of riding. This is what this creation wants to actively reveal.

The purpose of this invention is to provide a gearshift shaft force enhancement and stability protection device, which can be directly covered on the exposed part of the gearshift shaft and is applicable to the gearshift shafts of various vehicle bodies without affecting the original vehicle body structure design. After installation, it can protect the gearshift shaft, improve the stability and accuracy when shifting, and prevent the exposed gearshift shaft from being distorted and deformed when the vehicle falls and turns over, so as to improve the smoothness and safety of riding. The overall structure is simplified, which can also improve the overall convenience and practicality.

To achieve the above-mentioned purpose, the invention provides a transmission shaft force enhancement and stability protection device, which is applicable to various vehicle bodies with transmission shafts, and includes: a special stabilizer seat, a special transmission shaft clamp, a special torsion spring and a special plastic steel ring. The special stabilizer seat has at least one through-hole, through which one end of the speed shaft is passed, and a torsion spring positioning hole is arranged around the through-hole; the special speed shaft clamp also has at least one through-hole, through which one end of the speed shaft is passed, and a torsion spring positioning hole is arranged around the through-hole; one end of the special torsion spring is positioned in the torsion spring positioning hole of the special stabilizer seat, and the other end is positioned in the torsion spring positioning hole of the special speed shaft clamp; the special plastic steel ring is arranged in the through-hole of the special stabilizer seat, for one end of the speed shaft to pass through.

In a preferred embodiment, the custom stabilizer seat is preferably made of plastic steel, metal, aluminum, rubber or plastic.

The following is a specific and concrete example to illustrate the implementation of this creation. People familiar with this art can easily understand the other advantages and effects of this creation from the content disclosed in this manual.

The following is a description of the implementation of the present invention with reference to the drawings. It should be noted that the following drawings are simplified schematic drawings, and only illustrate the basic concept of the present invention in a schematic manner. Therefore, the drawings only illustrate the structure related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. The type, quantity and proportion of each component in actual implementation are not limited to the drawings, and can be changed according to actual design needs, which should be explained in advance.

First, please refer to Figures 1, 2, 3, 4 and 5, which are the three-dimensional structural exploded view, three-dimensional assembly view, three-dimensional exploded view from another angle, exploded view in use and reference view in use of a preferred embodiment of the invention. As shown in the figures, the invention of ... The special stabilizer seat 11 has at least one through hole 110, through which one end of the speed shaft 2 is passed, and a torsion spring positioning hole 111 is arranged around the through hole 110; the special speed shaft clamp 12 has at least one through hole 120, through which one end of the speed shaft 2 is passed, and a torsion spring positioning hole 121 is arranged around the through hole 120; one end of the special torsion spring 13 is positioned in the torsion spring positioning hole 111 of the special stabilizer seat 11, and the other end is positioned in the torsion spring positioning hole 121 of the special speed shaft clamp 12; the special plastic steel ring 14 is arranged in the through hole 110 of the special stabilizer seat 11, and one end of the speed shaft 2 is passed through.

And the invention can be installed on any vehicle body with a gear shaft 2, such as bicycles, road motorcycles, sports motorcycles, cruisers, touring motorcycles, agricultural vehicles, flat tire vehicles, adventure vehicles or off-road vehicles.

Through the above structure, as shown in FIG3 and FIG4, the special stabilizer seat 11 of the invention speed shaft force enhancement and stability protection device 1 can directly cover the exposed part of the speed shaft 2, and the two ends of the special torsion spring 12 are respectively positioned on the special stabilizer seat 11 and the special speed shaft clamp 12, thereby making it easy and accurate to switch gears and avoid the problem of skipping gears. In addition, the special plastic steel ring 14 is set so that the special plastic steel ring 14 covers the exposed speed shaft 2 to reduce the unnecessary shaking of the speed shaft 2 and make the speed shaft 2 more stable. Furthermore, the material of the special plastic steel ring 14 is highly plastic. When the vehicle body falls or turns over, it can prevent the gear shaft from being further damaged or prevent the special plastic steel ring 14 from being stuck inside. Even if the external impact force is too large and causes the special plastic steel ring 14 to be stuck inside, the special plastic steel ring 14 is highly plastic, and the special plastic steel ring 14 stuck by the strong external force can be quickly cut with tools. In addition, the special stabilizer seat 11 is not locked on the exposed part of the gear shaft 2, so it can also protect the gear shaft 2 when the vehicle falls or turns over.
