In recent years, due to Taiwan's opening of the import of heavy locomotives, people's transportation has gradually formed a trend of riding heavy vehicles in addition to safer cars and public transportation. Nowadays, most heavy locomotives are gear-shifting vehicles that need to be shifted by themselves. For gear-shifting vehicles, the braking device can not only control the braking of the vehicle, but also can be used to stabilize the body, that is, the braking device can be divided into front brake (front brake) And the rear brake (rear brake), the function of the front brake is to decelerate, and the function of the rear brake is to stabilize the body. Nowadays, most riders like to ride heavy motorcycles on mountain roads. Many winding mountain roads in narrow valleys require rear brakes. If you find that the speed of the near corner is too fast, causing the vehicle to throw and deviate from the route, you can use the rear brake to adjust the speed in the corner. For example, keep the throttle stable, and then use a small amount of rear brake to reduce some speed, and make the driving route can be retracted a bit. In contrast, using the front brake or skimming will transfer the weight to the front wheels and affect the traction of the tires, which may cause a crash. In this case, using the rear brake can reduce the speed of the car and allow the car to turn slowly according to the route the rider wants.

Since most of the rear brakes of gear-shifting cars nowadays are pedaled, sometimes when the curve of the driving route is too bend, the rider will easily use the rear brake because the knee is too low. When the rider’s foot is injured or the foot’s strength is not enough, the speed of cornering will be reduced, even You may crash the car as a result.

For the above reasons, some companies have introduced the “thumb brake”, which, as the name suggests, uses the thumb to perform rear braking. However, since the rear brake needs to be used, the thumb needs to be extended to control the rear brake, and the remaining fingers need to control the clutch. This control method , The rider is not able to intuitively react to the progress, which will affect the timing of using the brakes, and may even have the chance of crashing.

In view of the above problems, this creation provides a double master cylinder operating device, which is simple to operate and can control the rear brake and clutch, thereby achieving the purpose of convenient use.

In order to achieve the above objective, the double master cylinder operating device of the present invention includes a first master cylinder, a steering member, a pull rod, a pivotal member, a first push rod, a second master cylinder, and a second push rod. With a connecting piece. The steering member has a steering hole.
