Description
Technical field
The full double loop of the utility model brake system of car relates to automobile (air pressure) brake system, is specifically related to the full split brake system of being made up of the double loop braking of the forward and backward axle of automobile.
Background technology
Brake system of car is the important composition part of vehicle, also is the most important safe-guard system of automobile.Brake system is made up of Air compressor, braking pipeline, air tank, compressed air brake cylinder, brake activation valve class and drg etc. usually.The effect of brake system is the vehicle of will a run at high speed apply brake controllably, and vehicle can effectively be stopped.By the engine-drive Air compressor, produce pressurized air, pressurized air is transported to air tank through braking pipeline, in the air tank pressurized air through two pipelines to the upper and lower chamber of brake activation valve, brake activation valve is being subjected to pilot control, the vehicle of running is driven the person's of making brake activation device at the needs glancing impact, vehicle is implemented the braking of respective intensities.Glancing impact, braking pressure is exported in the upper and lower chamber of brake activation valve simultaneously, current vehicle is according to laws and regulations requirement, the split brake system that is adopted is the differential type relay valve that is equipped with two admission ports and a plurality of air extractor ducts on rear axle, thereby has guaranteed the double loop braking of rear axle, in case but front loop breaks down, front axle will be lost braking, and this will be a kind of very important unstable period for vehicle, a kind of potential safety hazard of also can saying so.
The utility model content
The purpose of this utility model provides a kind of full double loop brake system of car, no matter front axle or the rear axle to automobile all is provided with two braking pipelines, and access bi-pass quick-releasing valve or differential type relay valve, make the forward and backward axle of automobile all realize the double loop braking, give superior deceleration and stopping performance of vehicle and safety control.
Technical conceive of the present utility model is with single braking pipeline control of automobile front-axle, changes into two braking pipeline controls, and adopt bi-pass quick-releasing valve or differential type relay valve in the pressure gas braking pipeline, thereby reach the purpose of forward and backward axle full double loop braking.
The technical solution of the utility model is as follows:
This full double loop brake system of car, comprise air compressor, the pressed gas braking pipeline, brake activation valve, the bi-pass quick-releasing valve, the differential type relay valve, compressed air brake cylinder and drg, it is characterized in that in automobile pressure gas braking pipeline, automobile front axle and rear axle all are set to two braking pipelines, brake activation valve 1 is communicated with bi-pass quick-releasing valve 3 that is installed in automobile front axle and rear axle braking pipeline 2 or differential type relay valve 4, at the same time or separately through preceding compressed air brake cylinder 5, back compressed air brake cylinder 6, to preceding, rear brake is implemented braking, forms the full split brake system of being made up of braking of automobile front axle double loop and the braking of automobile hind axle double loop.
The epicoele air extractor duct 11 of brake activation valve 1 or cavity of resorption air extractor duct 12 are communicated with upper valve body air inlet control mouth 311 or 312, the rear axle loop differential type relay valve admission port 411 or 412 of front axle loop bi-pass quick-releasing valve 3 respectively, by corresponding air extractor duct, at the same time or separately through preceding compressed air brake cylinder 5, after compressed air brake cylinder 6 connect into split brake system with the forward and backward axle braking pipeline that is equipped with drg.
The epicoele air extractor duct 11 of brake activation valve 1 or cavity of resorption air extractor duct 12 are communicated with the air inlet control mouth 411 or 412 of front axle loop differential type relay valve 4, the admission port 311 or 312 of rear axle loop bi-pass quick-releasing valve 3 respectively, by corresponding air extractor duct, at the same time or separately through preceding compressed air brake cylinder 5, after compressed air brake cylinder 6 connect into split brake system with the forward and backward axle braking pipeline that is equipped with drg.
In brake activation valve when work,, its upper and lower chamber air extractor duct is implemented to brake with the forward and backward axle braking pipeline loop that is equipped with drg through preceding air chamber, rear gas chamber respectively at the same time or separately by bi-pass quick-releasing valve or differential type relay valve; Lost efficacy in case the epicoele of brake activation valve goes out the loop of interruption-forming, cavity of resorption goes out the loop of interruption-forming still can implement braking by bi-pass quick-releasing valve or differential type relay valve.In like manner, if going out the loop of interruption-forming, the cavity of resorption of brake activation valve lost efficacy, epicoele goes out the loop of interruption-forming still can pass through bi-pass quick-releasing valve or differential type relay valve, implements braking through preceding air chamber, rear gas chamber and the forward and backward axle braking pipeline loop that is equipped with drg respectively, reaches identical braking effect.Promptly be that two-tube its descends, realize the braking of full double loop.
The outstanding technique effect of the utility model is that compared with the prior art, assembly technology is constant, and cost increases few, but can further improve the safety of operational vehicle braking.
Description of drawings
The full split brake system structural representation of Fig. 1 the utility model.
Fig. 2 exchanges bi-pass quick-releasing valve and differential type relay valve positional structure scheme drawing by Fig. 1.
The specific embodiment
How now further specify the full split brake system of the utility model in conjunction with the accompanying drawings operates.
Be equipped with the automobile of full split brake system of the present utility model, when being in operation, it needs glancing impact, the pilot control brake activation valve, brake activation valve work, as shown in Figure 1, outlet 11 of brake activation valve 1 epicoele and cavity of resorption outlet 12, import pressurized airs through braking pipeline 2 to bi-pass quick-releasing valve 3 or differential type relay valve 4 simultaneously, brake activation valve 1 epicoele give vent to anger 11 mouthfuls respectively with the admission port 312 and rear axle differential type relay valve 4 admission ports 412 UNICOMs of front axle bi-pass quick-releasing valve 3, the air extractor duct 321 of bi-pass quick-releasing valve 3,322 and rear axle differential type relay valve 4 air extractor ducts 421,422 respectively with preceding compressed air brake cylinder 5, back compressed air brake cylinder 6 UNICOMs, form one group comprise before, full double loop 2 brake system of rear axle; Brake activation valve 1 cavity of resorption air extractor duct 12 respectively with front axle bi-pass quick-releasing valve 3 admission ports 311 and rear axle differential type relay valve 4 admission ports 411 UNICOMs, the air extractor duct 321,322 of bi-pass quick-releasing valve 3 and rear axle differential type relay valve 4 air extractor ducts 421,422 respectively with preceding compressed air brake cylinder 5, back compressed air brake cylinder 6 UNICOMs, form full double loop 2 brake system that another group comprises forward and backward axle.When bi-pass quick-releasing valve or differential type relay valve input pressurized air is distinguished in brake activation valve 1 upper and lower chamber simultaneously, the gaseous tension height of which bar pipeline, then send brake action by this high gaseous tension pipeline, as long as do not break down simultaneously in brake activation valve 1 upper and lower chamber, vehicle can form full split brake system.
Structure shown in Figure 2 is implemented same as shown in Figure 1, just exchanged bi-pass quick-releasing valve 3 and differential type relay valve 4 in front axle double loop and the two circuit position of rear axle, its function is in full accord.
