The truck uses compressed air to disengage and recombine the amt clutch actuator to complete the start and shift gears. A concentric pneumatic clutch actuator contains all elements connected to the gearbox system to disengage and reengage the clutch as required by the gearbox.

The concentric pneumatic clutch actuator is modified from the traditional mechanical structure, using automatic control cylinders instead of the traditional booster cylinders. While the clutch pedal is eliminated, and the piston moves horizontally to realize the separation and engagement action by controlling the air pressure inside the actuator cylinder. The separation process and the engagement process are controlled by a set of high-speed switching valves, and the separation and engagement speed is controlled by adjusting the duty cycle of the switching valves.

Pneumatic Clutch Working Principle

A concentric pneumatic clutch actuator works on the principle of air pressure. It is a type of clutch that uses compressed air to transmit torque from a drive source to a driven load. The basic components of a concentric pneumatic clutch actuator include a compressor, an air storage tank, a control valve, and a clutch mechanism.

Here's how it works:

The compressor compresses air from the atmosphere and stores it in the air storage tank.

The control valve regulates the air flow from the storage tank to the clutch mechanism.

When the control valve opens, compressed air flows into the clutch mechanism, which creates a high-pressure air gap between the clutch plates.

The high-pressure air gap exerts a force on the clutch plates, causing them to engage and transmit torque from the drive source to the driven load.

When the control valve is closed, the air flow stops, and the air pressure in the clutch mechanism decreases, causing the clutch plates to disengage.

In summary, the pneumatic clutch works by using air pressure to engage and disengage the clutch plates, allowing for the transmission of torque from the drive source to the driven load.

Concentric Pneumatic Clutch Actuator Function

A concentric pneumatic clutch actuator that contains all elements connected to the gearbox system to disengage and reengage the clutch as required by the gearbox.

Continuous sliding operation and high-frequency operation are possible by the concentric pneumatic clutch actuator.

The concentric pneumatic clutch actuator has a disc with a heat sink with a large heat capacity, so it has a good heat dissipation effect.

The concentric pneumatic clutch actuator has a high speed and smooth operation and has stable working characteristics.

The structure of the concentric pneumatic clutch actuator is simple and easy to maintain, and it has a long service life.

AMT Clutch Actuator Design

FOR AMT GEARBOX

The automatic clutch actuator consists of an electric oil pump, solenoid valve, and clutch cylinder. When the ECU issues a command to drive the electric oil pump. The high-pressure oil generated by the electric oil pump is delivered to the clutch cylinder through the solenoid valve. The ECU controls the electric flow of the solenoid valve to control the flow of fluid and the channel change of fluid to realize the movement of the piston of the clutch cylinder, thus completing the clutch action when the car starts and shifts gears.

Pneumatic Automatic Clutch Actuator Safety

Pass a million life tests.

The automatic clutch actuator is able to drive a vehicle with a manual transmission absolutely requires proper operation of the clutch drive system. Therefore, total reliability and long service life must be guaranteed.
