Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
If Fig. 1 is prior art schematic diagram, this system comprises brake activation valve 1, air tank 2, relay valve 3, air pressure controlling valve 4, fast filling valve 5, compressed air brake cylinder 6 and gas pressure regulator 7.The admission port of relay valve 3 is connected with air tank 2 and compressed air brake cylinder 6 respectively by pipeline 8 with air extractor duct, air pressure controlling valve 4 is located on the pipeline between relay valve 3 air extractor ducts and compressed air brake cylinder 6, air tank 2 is connected by pipeline 8 with fast filling valve 5, and the outlet of this section of pipeline is connected between relay valve 3 and air pressure controlling valve 4, fast filling valve 5 is that model is the electromagnetic valve of 3754010-T0101.The mouth of gas pressure regulator 7 is electrically connected by wire harness 9 with air pressure controlling valve 4 and fast filling valve 5 respectively, and the admission port of brake activation valve 1 is controlled mouth 3.1 with first of air tank 2 and relay valve 3 with air extractor duct respectively by pipeline 8 and is connected.This kind increases the inflatable structure of fast filling valve 5, accelerate the speed that compressed air brake cylinder 6 air pressure increase, meet to a certain extent the requirement of regenerative brake ride comfort, but in the process of fast aeration, pipeline by fast filling valve 5 can source channels as air feed, be subject to the restriction of the volume of fast filling valve own, gas circuit is all less by the aperture of valve body, and this will become one of the factor of compressed air brake cylinder pressure rises speed that affects.And connect between relay valve 3 and compressed air brake cylinder 6 because need adopt the air extractor duct of three-way pipe fast filling valve 5, cause the tube bank cloth of car load to be set up also succinct not.
Fig. 2 is the utility model structural representation, and the utility model adopts the differential relay valve 10 with two control mouths, and the model of this differential relay valve is 3527RC16-001.Control mouthfuls 10.1 by first of air tank 2 and differential relay valve 10 and be connected, by the delivery conduit of fast filling valve 5 from original on the second control mouth 10.2 that moves to differential relay valve 10 between relay valve 3 and air pressure controlling valve 4.
