Problems solved by technology

[0003] 1. In the electromagnetically controlled anti-lock braking device, there are mechanical, hydraulic and electronic structural forms, so the structure is complex and the cost is high
[0004] 2. During the working process of the electronically controlled anti-lock braking device, the control signal and kinetic energy have to undergo the conversion of various energy forms such as electromechanical, electric and hydraulic, which not only prolongs the information transmission time, but also reduces the anti-lock braking performance The sensitivity of the device, and it is easy to cause signal distortion, which affects the adaptability of anti-lock braking

Abstract

The hydraulic ABS device for motor vehicle includes braking pump, brake and braking pressure regulator. It features the braking pressure regulator consists of casing, stepped plunger, spring, and end cap. The stepped plunger is installed inside the work cavity of the casing to divide the work cavity into braking cavity and control cavity. The braking cavity is communicated via oil channel with the braking pump and the brake, and the control cavity is communicated via oil channel with controlling pressure regulator, which is driven with the inertial force and installed on the vehicle frame. The controlling pressure regulator consists of cylinder, plunger, isolator, flywheel with cam, shaft disc, transmission shaft and casing. The present invention has the advantages of direct utilization of inertia energy for signal transmission and pressure regulation, simple structure of the device, small size, low cost, high sensitivity, etc.

Description

technical field [0001] The invention relates to a motor vehicle brake device, in particular to a motor vehicle hydraulic anti-lock brake device. Background technique [0002] At present, the known anti-lock braking devices for motor vehicles include electromagnetic control type and mechanical type. Because the electromagnetic control type anti-lock braking device is more sensitive than the mechanical type, it is widely used. However, electromagnetic devices also have the following problems: [0003] 1. In the electromagnetically controlled anti-lock braking device, there are various mechanical, hydraulic and electronic structural forms, so the structure is complicated and the cost is high. [0004] 2. During the working process of the electronically controlled anti-lock braking device, the control signal and kinetic energy have to undergo the conversion of various energy forms such as electromechanical, electric and hydraulic, which not only prolongs the information transmi...
