Product Description

Air Brake System Auto Solenoid Coil

ABS Auto solenoid valve coils control process:
1) Inflation process:
When the driver steps on the brake pedal, the car begins to decelerate. At this time, the wheel is not immediately locked, ABS can not afford the effect; the intake valve control coil and the exhaust valve control coil are not energized, the intake and exhaust ports of the solenoid valve are connected, which is equivalent to a straight-through joint.

2) Exhaust process:
Following the constant inflation of the brake chamber, the braking force of the tire is getting bigger and bigger, and the wheel gradually becomes locked. The ABS control unit will properly release the air in the brake chamber to avoid the wheel lock. This process is the exhaust process.

When exhausting, the intake valve control coil is energized, and the exhaust valve control coil is also energized, so that the air inlet is sealed, and the air outlet is connected to the exhaust port to complete the exhaust operation.

3) Pressure keeping process:
When the brake chamber is exhausted, not all the air in the brake chamber is released, only a part is released. When the ABS control unit detects that the wheel is no longer locked, the exhaust will be turned off, and the system will be closed. The air pressure in the moving air chamber is unchanged, and the pressure is maintained. In this way, for a period of time, the braking force will remain unchanged and the wheels will not lock.

When the pressure is maintained, the intake valve control coil is energized, and the exhaust valve control coil is de-energized. The air inlet is still sealed, and the air outlet is sealed to complete the pressure.

Brief introduction of ABS (air brake system with ZR-D005 solenoid coils):

ABS is a mechanism that brakes the entire vehicle with the damping effect of engine compression. When the air brake system works, the brake valve plate closes the exhaust pipe, and the linkage lever pulls the throttle lever oil pump to stop the oil supply, which is the compressor becomes the compressor, and the air brake system valve plate prevents the compressed gas from being discharged, At this time, the whole vehicle is traveling with the gear, and the air brake system has a braking effect on the whole vehicle.

The function of the air brake is the parking brake. After stopping, the compressor pump stops working, there is no air pressure in the brake system, the brake brake spring is extended, and the brake pad is pushed to lock the brake drum. Prevent slipping. After the vehicle is started, the air pump works to the specified air pressure and then compresses the air brake spring to relax the brake drum. The vehicle can run normally.

The working principle of the pneumatic brake system: the air compressor driven by the engine first inputs the compressed air into the wet gas storage tank through the one-way valve. After the compressed air is cooled in the wet gas pipeline and separated by oil and water, it is divided into two loops: one loop The middle chamber of the air reservoir and the double chamber brake valve leads to the rear brake chamber; the other circuit passes through the lower chamber of the air reservoir and the double chamber brake valve to the front brake chamber. When one of the loops fails, the other loop can continue to work to ensure that the car has a certain braking capacity, thus improving the safety of the car.
