Principle of work of the present utility model is:
As shown in Figure 1, the inlet end of total intake interface 7 and the front braking air drum 104 of passenger vehicle or brake air drum 111 afterwards and be connected, outlet side is divided into three channel gas source through two threeways, one road source of the gas is linked into the air intake opening of solenoid valve 3, the gas outlet of solenoid valve 3 receives the control end of left relay valve 5, right relay valve 12 more respectively by threeway, the power supply signal end of solenoid valve 3 connects 24V direct supply 1 by signal wire through solenoid valve wiring harness interface 21 and double-pole switch 2.When double-pole switch 2 disconnects, the gas outlet of solenoid valve 3 is closed, and now, because the control end of left relay valve 5 and right relay valve 12 does not have source of the gas to flow into, therefore, the air intake opening of left relay valve and right relay valve does not communicate with gas outlet.When double-pole switch 2 closes, the gas outlet of solenoid valve 3 is opened, and source of the gas flows into the control end of left relay valve 5, right relay valve 12 respectively by threeway, and the air intake opening of left relay valve 5 and right relay valve 12 communicates with gas outlet.
Two-way source of the gas is divided into two-way according to passenger vehicle left and right air chamber in addition, respectively through the pressure regulation of left and right linear voltage regulation valve, sets its pressure.The gas setting air pressure receives the air intake opening of left relay valve 5, right relay valve 12 respectively, when double-pole switch 2 closes, the air intake opening of left relay valve 5 and right relay valve 12 communicates with gas outlet, the gas setting air pressure first flow into the air intake opening of left and right shuttle valve respectively from the gas outlet of left and right relay valve, and then flow to left and right ABS(anti-blocking brake system respectively from the gas outlet of left and right shuttle valve) air intake opening, thus obtain the air pressure that presets.
In order to ensure vehicle safety, barometric control unit described in the utility model is connected in parallel on the basis of original coach braking pressure pipeline, when push down on the pedal (foot valve) time, pressure gas enters from the air intake opening of left and right shuttle valve, discharge from the gas outlet of left and right shuttle valve rapidly, do not affect the security of vehicle.
As shown in Figure 4, before being ABS during failure test, the gas outlet of braking air drum 104 before total intake interface 7 of the barometric control unit 101 lost efficacy before ABS is connected to by threeway, the gas outlet of master cylinder is divided into two-way by threeway, is connected respectively with the revolver intake interface of the barometric control unit 101 for losing efficacy before ABS, right intake interface of taking turns.Give vent to anger interface, right interface of giving vent to anger of taking turns of the revolver of the barometric control unit 101 lost efficacy before ABS is connected respectively to revolver ABS air intake opening and rightly takes turns ABS air intake opening.Losing efficacy before carrying out ABS in process of the test, in order to reach the left and right wheel of front axle just close to the requirement of the critical conditions of locking, by accurately arranging the pressure of left and right linear voltage regulation valve, regulating the air pressure of whole pipeline.When solenoid valve 3 switch closes, the gas setting air pressure enters into respectively left and rightly takes turns ABS air intake opening; Now, observe wheel lock up situation, the continuously pressure of increasing or decreasing left linear voltage regulation valve and right linear voltage regulation valve, till pipeline air pressure makes the critical conditions of left and right front-wheel close to locking.
As shown in Figure 4, after being ABS during failure test, total intake interface 7 of the barometric control unit 110 lost efficacy after ABS is connected to the gas outlet of rear braking air drum 111 by threeway, the gas outlet of the relay valve 108 in passenger vehicle brake piping is divided into two-way through threeway, be connected with the left and right intake interface of taking turns of the barometric control unit 110 for losing efficacy after ABS respectively, the barometric control unit 110 lost efficacy after ABS left and right is taken turns interface of giving vent to anger and is connected respectively to and left and rightly takes turns ABS air intake opening.After carrying out ABS in failure test process, in order to reach the left and right wheel of rear axle just close to the requirement of the critical conditions of locking, by accurately arranging the pressure of left and right linear voltage regulation valve, regulate the air pressure of whole pipeline.When solenoid valve 3 switch closes, the gas setting air pressure enters into respectively left and rightly takes turns ABS air intake opening; Now, observe wheel lock up situation, the continuously pressure of increasing or decreasing left linear voltage regulation valve and right linear voltage regulation valve, till pipeline air pressure makes the critical conditions of left and right front-wheel close to locking.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
