Abstract
The present invention relates to an M*4 pipeline hydraulic brake structure for automobiles. The original automobile hydraulic brake master pump with single pipeline is changed into a hydraulic brake master pump with double pipelines. The hydraulic brake master pump with double pipelines controls and replaces a brake master pump with double pipelines for a vacuum booster pump, and thus, the brake purpose by four pipelines is achieved. Hydraulic brake pipelines of four wheels are respectively provided with an indication signal switch for monitoring and alarming. The present invention enhances the brake effect, and can prevent the oil leakage of the brake cylinder pipeline of one wheel from causing the other wheel to generate poor brake fault. An indication alarm in a driving cab can send the response to drivers in time on whether the hydraulic brake pressure of each wheel is normal or not to ensure safety.
Description
Technical field
The invention belongs to the technical field of brake device for car, relate to hydraulic vehicle brake system, particularly a kind of automobile 4 pipeline hydraulic brake devices.
Background technology
Present known hydraulic vehicle brake system is four-wheel braking before and after the dual circuit, does not brake indicating device along separate routes and establish each, and one take turns the brake piping leakage of oil and can cause other to take turns the braking of agitating and lost efficacy simultaneously, has had a strong impact on the automobile brake effect.Can not find it is which side wheel leakage of oil to this navigating mate at once.
Summary of the invention
The purpose of this invention is to provide a kind of 4 and have the automobile 4 pipeline hydraulic brake devices that single-wheel pipeline brake-pressure is made comments and instructions lamp along separate routes.It has remedied the deficiency of existing hydraulic braking, has improved the safety arrestment coefficient.
The object of the present invention is achieved like this: be to repack original single tube road hydraulic braking master cylinder for automobile into the dual line braking master cylinder, and dual circuit drag master cylinder is fixedly mounted on directly pushing place of stretcher push rod, two brake hydraulic delivery pipes of master brake cylinder are connected respectively with the dual circuit brake pump of two band vacuum booster pumps respectively.The dual circuit brake pump location and installation of two band vacuum booster pumps is at the fixed position of automotive frame, the dual circuit brake pump (have vacuum lamp with oil brake pipe etc.) of two band vacuum booster pumps is connected with drag master cylinder hydraulic pipe with the brake vacuum tube respectively, four brake pipes of brake hydraulic output directly are connected with brake cylinder respectively, and at the pipeline end 4 indication monitoring switches of reporting to the police is housed respectively.The degree of vacuum (air pressure) that vacuum cylinder is equipped with unidirectional vacuum choke valve, vacuum cylinder is respectively directly supplied with by vacuum pump or driving engine.Four brake fluid pressure delivery pipes of two dual line braking brake pumps of band vacuum booster pump directly are connected with the wheel cylinder of 4 wheels respectively, each the drag pipe of four-wheel and the near-end of wheel cylinder all are equipped with a brake fluid pressure monitoring, alarming indicator signal switch, the braking indicator signal of four-wheel is installed on the gauge panel in the operator's compartment, just shinny when clearing lamp that the brake-pressure of brake line is just often respectively taken turns, just do not work as a certain pipeline brake-pressure deficiency, indicator lamp.So just, can in time braking effect be fed back to and congratulate the person of sailing, in time provide the guilty culprit of brake system.Guarantee safe driving so that in time discharge fault.
Because adopted above brake structure, improved braking effect, its element is easily got, technology is simple.
Be described further below in conjunction with drawings and Examples.
