The utility model discloses a theory of operation is:
as shown in fig. 2(a) and 2(b), the case of the ASR valve 6 and the two-way one-way valve 7; in the usual case, these two valves work in combination; the working conditions under this connection mode are: when a brake is stepped on, the air consumption of the brake system is small, the air of a brake foot valve directly enters the two-way one-way valve 7 from the interface four 11 of the two-way one-way valve 7, the valve core is pushed to the leftmost side of the channel in the two-way one-way valve 7, the interface three 10 of the two-way one-way valve 7 is blocked, the air is discharged from the interface five 12 of the two-way one-way valve 7 and is supplied to the brake system, the air of the air storage tank enters from the interface one 8 of the ASR valve 6, the ASR valve 6 is in a closed state, and the air is stopped at the position.
When the vehicle needs emergency braking, according to the stepping rate of a brake pedal, the ASR valve 6 can be quickly controlled through the brake system control unit, the electromagnet of the ASR valve is electrified, gas in the gas storage tank quickly enters the ASR valve 6 from the first interface 8 of the ASR valve 6 and then exits from the second interface 9 of the ASR valve 6, the gas pressure of the gas storage tank is higher than that of the gas at the foot valve and faster than that of the brake foot valve, so that the gas can enter from the third interface 10 of the bidirectional one-way valve 7 to jack the valve core to the rightmost side of the channel in the bidirectional one-way valve 7, the fourth interface 11 of the bidirectional one-way valve 7 is blocked by the valve core at the moment, the gas in the gas storage tank exits from the fifth interface 12 of the bidirectional one-way valve 7, the gas in the main gas tank is supplied to the system, and a larger control gas pressure is quickly established, so that the response time of the brake system is prolonged, and the braking distance of the vehicle is shortened.
When a driver does not step on a brake and the vehicle inclines to turn over, stability control needs to be carried out through a brake system, the ASR valve 6 is powered on at the moment, an electromagnet of the ASR valve is opened, gas in the gas storage tank enters the ASR valve 6 from a first interface 8 of the ASR valve 6 and then flows out from a second interface 9 of the ASR valve, the gas can enter from a third interface 10 of the bidirectional one-way valve 7 and pushes the valve core to the rightmost side of a channel in the bidirectional one-way valve 7, at the moment, the valve core blocks a fourth interface 11 of the bidirectional one-way valve 7, and the gas in the gas storage tank flows out from a fifth interface 12 of the bidirectional one-way valve 7, so that the gas in a main gas tank is supplied to the system, and the brake efficiency is improved.
