As shown in fig. 6, when the waterproof type anti-lock brake control module of the present embodiment is applied to an actual operation, that is, when the present embodiment is connected to a whole vehicle component, the first air inlet of the waterproof type anti-lock brake control module 910 of the present embodiment is connected to the master cylinder 920, and the two first air outlets of the waterproof type anti-lock brake control module 910 are respectively connected to the front axle brake air chamber 930. The following takes conventional braking, ABS electronic control pressure maintaining and ABS electronic control pressure reducing as examples to respectively illustrate the specific working principle of this embodiment:
in the conventional braking process, when a driver steps on a brake pedal, air in an air outlet of a brake master valve enters a first air inlet of a waterproof anti-lock brake control module through a pipeline, and the air passes through a first air inlet channel and a second air inlet channel of an ABS (anti-lock brake system) electromagnetic valve through a first air channel. And the gas in the second air inlet channel reaches the second control air channel through a second control valve of the ABS electromagnetic valve and then reaches the second control air chamber. Wherein the gas in the first intake air passage is blocked by the first control valve. The first control air chamber is communicated with the first control air passage and the first exhaust air passage are communicated with the first exhaust port, and the first control air chamber has no air pressure. The rubber diaphragm of the second diaphragm valve component is in a stop state with the valve seal closed downwards under the action of air pressure of the second control air chamber, so that the first air outlet and the first exhaust port are stopped. Because the first control air chamber has no air pressure, the air of the first air passage pushes the rubber diaphragm of the first diaphragm type valve component to be opened with the valve, and the air reaches the first air outlet through the valve, the second air passage and the third air passage and then reaches the single-side brake air chamber of the whole vehicle connected with the first air outlet to realize braking. Because the waterproof anti-lock brake control module of this embodiment connects in parallel and integrates two sets of ABS solenoid valves, and in a similar way, the gas reaches the first gas outlet through the valve, the second gas flue, the third gas flue that another ABS solenoid valve corresponds to, reaches the whole car that links to each other with first gas outlet again and other limit brake chamber realizes the braking to realize the braking simultaneously of whole car front axle.
When a driver looses the brake pedal, the gas of the first air inlet is exhausted through the exhaust port of the brake master valve, the gas of the second control air chamber is exhausted from the first air inlet through the original path during braking, the second control air chamber has no air pressure, the brake air pressure of the first air outlet pushes the rubber diaphragm of the second diaphragm valve assembly to be opened through the third air passage, at the moment, the second air passage, the third air passage and the first exhaust port are communicated, and the gas of the brake air chamber is exhausted through the first air outlet and the first exhaust port to release braking. In a similar way, the air in the brake air chamber on the other side is exhausted through the corresponding first air outlet and the first exhaust port to release the brake, so that the brake of the front axle of the whole vehicle is released.
In summary, the working principle during normal braking can be summarized as follows: when a driver steps on a brake pedal, the first control air chamber is free of air, the first diaphragm type valve assembly is in an opening state, namely the first air passage and the second air passage are in a communicated state, an air source of the first air inlet passes through the first air passage, the second air passage and the third air passage through a valve of the first diaphragm type valve assembly to reach the first air outlet, at the moment, the second control air chamber is filled with air to enable the valve of the second diaphragm type valve assembly to be in a closing state, and the second air passage, the third air passage and the first exhaust port are cut off, so that the purpose of braking is achieved. When the driver releases the pedal, the brake air pressure of the brake spring cylinder is exhausted from the exhaust port of the brake main valve through the first air outlet through the original path, and the brake is released.
In the conventional braking process, the ABS braking principle is as follows: when an electronic control unit ECU receives wheel speed feedback signals from a wheel speed sensor of a whole vehicle through an electrical connection interface, and the ECU calculates that the whole vehicle has wheel brake pressure which is too high and has a tendency of locking, the ECU controls a first control valve and a second control valve of two groups of ABS electromagnetic valves through an electrical pin in an electrified way, so that the real-time regulation of electric control pressure reduction of a first air outlet is realized; when the ECU calculates that the brake pressure is too small, the ECU controls the first control valves of the two groups of ABS electromagnetic valves and the first control valve to be powered off through the electric pins, so that the real-time regulation of the electric control pressurization of the first air outlet is realized; when the ECU calculates the brake pressure to be proper, the ECU controls the first control valves of the two sets of ABS electromagnetic valves to be powered off and the second control valves to be powered on through the electric pins, and the real-time adjustment of the electric control pressure maintaining of the first air outlet is achieved. The ABS regulation and braking function is realized through continuous real-time regulation and control of pressurization, pressure maintaining and pressure reduction, and accurate anti-lock braking is carried out on each brake air chamber of the whole vehicle.
In this embodiment, the boosting function is the same as the conventional braking principle, and is not described herein.
In the ABS electric control pressure maintaining process, when the ECU calculates the brake pressure to be proper, the ECU controls the first control valves of the two sets of ABS electromagnetic valves to be powered off and the second control valves to be powered on through the electric pins, and first gas of the first gas inlet passes through the first gas inlet air passage and the second gas inlet air passage of the ABS electromagnetic valves through the air passages. And the gas in the second air inlet channel reaches the second control air channel through a second control valve of the ABS electromagnetic valve and then reaches the second control air chamber. The gas in the first gas inlet channel passes through the first control valve and the first control gas channel and then reaches the first control gas chamber. The rubber diaphragms of the first diaphragm valve component and the second diaphragm valve component are closed downwards and sealed with the valves under the action of air pressure of the first control air chamber and the second control air chamber to be in a stop state, so that the second air passage, the third air passage and the first exhaust port are stopped, the second air passage and the first air passage are stopped, namely the first air outlet and the first exhaust port are stopped, and the first air outlet and the first air inlet are stopped. Realize that the atmospheric pressure of first gas outlet keeps invariable, realize the pressurize function.
In the ABS electric control pressure reduction process, when the ECU calculates that the braking pressure of wheels of the whole vehicle is too high and the vehicle tends to be locked, the ECU controls the first control valve and the second control valve of the two sets of ABS electromagnetic valves to be electrified through the electric pins, and the gas of the first gas inlet passes through the first gas inlet channel and the second gas inlet channel of the ABS electromagnetic valves through the first gas channel. Wherein the gas of the second air inlet channel is cut off by the second control valve of the ABS electromagnetic valve. The second control air flue is communicated with the second exhaust air flue, the air of the second control air chamber is exhausted through the second control air flue, the second exhaust air flue and the first exhaust port, the air of the second air flue and the third air flue pushes the rubber diaphragm of the second diaphragm type valve assembly to move upwards to open the valve, the second air flue, the third air flue and the first exhaust port are communicated, and the air of the first air outlet is exhausted through the second air flue, the third air flue and the first exhaust port to reduce pressure. Meanwhile, the gas in the first air inlet channel passes through the first control valve and the first control air channel and then reaches the first control air chamber. The rubber diaphragm of the first diaphragm valve component is downwards closed with the valve seal under the air pressure action of the first control air chamber to be in a stop state, so that the second air channel is stopped from the first air channel, namely the first air outlet is stopped from the first air inlet, and the air of the first air inlet cannot be supplemented to the first air outlet, so that the air pressure of the first air outlet is reduced, and the pressure reduction function is realized.
In summary, the integrated design of the embodiment integrates the anti-lock system controller and the anti-lock execution mechanism for the commercial vehicle to form the waterproof anti-lock brake control module for the chassis, and has the advantages of high integration level, light weight, convenience in pipeline connection, short wiring harness and high cost performance, and the competitiveness of the whole vehicle is improved. And adopt flat design with ABS solenoid valve, with the valve body form upper and lower stacked structure, simple to operate easily realizes the automation, improves production efficiency, improves the product uniformity, the cost is reduced.
