Brake device with dynamic adjustment function of handle lever ratio

This creation is related to the field of braking technology, especially a kind of braking device with the function of dynamically adjusting the lever ratio of the handle.

According to the configuration of the brake system of the robot bike and the electric motorcycle, it is mainly composed of the master cylinder, the brake hose, and the brake calipers. The braking methods are divided into drum brakes and disc brakes. Except for the caliper parts and braking methods, there are slight differences. In addition, it mainly uses friction to transform kinetic energy into heat and dissipate it in the air, thereby enabling the vehicle to achieve the function of decelerating or stopping.

As shown in the first figure, the brake master cylinder 90 is mainly fixed to the handlebar 91, and the handle 92 is pivotally connected to the handle base 94 by the first pivot 93, and then cooperates with the first pivot 93 in the braking system of a general robot bicycle and electric motor car. The two pivots 95 are connected to the actuating rod 96 of the brake master cylinder 90. When the robot bike is driving and the driver realizes that there is a situation ahead, he immediately presses the handle 92 of the brake master cylinder 90, so that the hydraulic oil is transmitted to the brake calipers via the brake master cylinder 90 and the brake hose to generate braking force and make the vehicle Decelerate or stop.

In the actuating mechanism of the master brake cylinder 90, the distance between the force application portion 97 of the handle 92 and the first pivot 93 constitutes an application arm, and the center distance between the first pivot 93 and the second pivot 95 is Is a resistance arm, and this leverage ratio is that the force arm is greater than the resistance arm , In order to achieve effort-saving effect.

Although the handle 92 of the brake master cylinder 90 can set the user's braking feel in the size configuration of the resistance arm and the application arm, the preference of the brake feel is subjective to the user, and some users prefer a harder feel. , There are also users who prefer a softer feel, and the existing brake master cylinder 90 is unable to take into account dynamic adjustment, convenient operation and use effects in the mechanism design of adjusting the lever ratio of the setting handle 92. Therefore, how to solve the above-mentioned problems is the subject of urgent research by the relevant industry.
