Disc hydraulic anti-lock brake and brake system

Abstract

A disc hydraulic anti-lock brake and a brake system are provided. The disc hydraulic anti-lock brake includes a support (400) provided with a first opening (415), a core tube (502), a first passage (406), a second passage (412), a third passage (409) and a braking sheet base; a first piston (501) disposed in the first opening (415), with a first cavity being communicated with the first passage (406) and a service brake valve, and the first piston (501) being provided with a second opening (504); a second piston (506) disposed in the second opening (504), with a second cavity (508) being communicated with the core tube (502), the second passage (412) and a parking brake valve; an elastic member (505) disposed between the second piston (506) and the bottom of the second opening (504); a braking terminating system provided with a pump (315) and an unloading valve (322); a braking disc (900) provided with a counting gear ring and a mounting portion; and an anti-lock system provided with acounting sensor, a motor (309), and a liquid drainage valve (310). A liquid inlet of the liquid drainage valve (310) is communicated with the first cavity through the third passage (409). According tothe brake, the support (400) is provided with the first opening (416) and the second opening (417), and the first piston (601) and the second piston (701) are disposed in the first opening (416) andthe second opening (417) respectively. The brake system can achieve service braking, parking braking and anti-lock braking, and is easy to achieve.

Description

technical field [0001] The invention relates to the field of braking, in particular to a disc hydraulic anti-lock brake and a braking system used for equipment including rotational motion of wheels and the like. Background technique [0002] With the increasing number of various vehicles, machinery and other equipment, people have higher and higher requirements for safe and energy-saving use of vehicles, machinery and other equipment, and the quality of braking performance is an important factor for the safe operation of vehicles and machinery. in accordance with. Especially in the case of fast vehicle speed and heavy weight, braking inertia has more and more influence on safe driving. How to reduce and optimize the impact of braking inertia on equipment braking including vehicles and machinery (such as hoisting) , is a problem that all people in the industry need to work tirelessly to solve. [0003] At present, the existing vehicles on the market have drum brakes and dis...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing vehicles on the market have drum brakes and disc brakes, and most of the disc brakes are used on small cars. Most of the commercial vehicles still have drum brakes and most of them are air-controlled. Low-speed vehicles use hydraulic control and oil-air hybrid braking. Although they can all achieve braking to slow down and stop the vehicle, they have the disadvantages of taking up a lot of space, difficult to arrange, poor braking performance, worse heat dissipation, and braking. The system has many shortcomings such as complex structure, poor effect, high cost, and inconvenient operation.

[0004] The existing ABS (Ant-ilock Brake System, anti-lock braking system) on the market can also reduce or optimize the impact of braking inertia on motor vehicle braking, but the existing ABS is due to its complex structure and safety factor Low and high cost, so the existing ABS cannot be widely promoted

[0005] The inventor applied on August 19, 2014, the application number is 2014104098460, and the invention name is the Chinese invention patent of hydraulic anti-lock brake wheel cylinder and axle brake system. Although the above problems have been solved, the processing is difficult and the realization difficulty
