Description
Technical field
The utility model relates to the vehicle brake technology field, relates in particular to a kind of pneumatic brake vehicle that is applicable to the vehicle brake control apparatus of pneumatic brake vehicle and has this vehicle brake control apparatus.
Background technology
In the prior art, when carrying out the car brakeing design, usually forward and backward braking air tank is placed on front part of vehicle.Design for the front wheel brake control loop, as shown in Figure 1, because of preceding compressed air brake cylinder 1 and preceding braking air tank 6 nearer apart from 8 bonded assembly master brake cylinder 4 of brake pedal, before brake servo circuit all be directly to use pipeline to be connected with preceding compressed air brake cylinder 1 cavity of resorption that is used for front wheel brake of preceding braking air tank 6, master brake cylinder 4, only between the cavity of resorption of two preceding compressed air brake cylinders 1 and master brake cylinder 4, connect rapid release valve 2, the exhaust of brake servo circuit before accelerating, the reliability of assurance secondary braking.
The front wheel brake control loop principle of work of the vehicle brake control apparatus of above-mentioned prior art is: when chaufeur is stepped on brake pedal 8, gas is realized front wheel brake by preceding braking air tank 6 compressed air brake cylinder 1 via the cavity of resorption of master brake cylinder 4, rapid release valve 2 and before arriving.Behind loosen the brake, the gas in the preceding compressed air brake cylinder 1 leads to atmosphere by the exhausr port (not shown) of rapid release valve 2, the braking return.
And for the design of trailing wheel brake servo circuit, as shown in Figure 1, because of the brake application by spring air chamber 7 that is used for trailing wheel braking far away apart from master brake cylinder 4, after brake servo circuit all be that use relay valve 5 is connected between the epicoele that is used for the trailing wheel braking of back braking air tank 3 and master brake cylinder 4 and two brake application by spring air chambers 7, to improve the retro-speed of trailing wheel, to reach the designing requirement that front and back wheel should be braked simultaneously.
The trailing wheel brake servo circuit principle of work of the vehicle brake control apparatus of prior art is: after using relay valve 5, gas in the back braking air tank 3 is divided into two-way, one the tunnel is control gaseous, one the tunnel is effect gas, when chaufeur is stepped on brake pedal 8, the control gaseous that back braking air tank 3 comes out arrives the signal port of relay valve 5 via the epicoele of master brake cylinder 4, push the admission port that relay valve 5 links to each other with back braking air tank 3 open, effect gas in the back braking air tank 3 is able to arrive brake application by spring air chamber 7 via relay valve 5, realizes the trailing wheel braking.Behind loosen the brake, the gas in the brake application by spring air chamber 7 leads to atmosphere by relay valve 5 exhausr port (not shown)s, the braking return.
