Relevant knowledge
Some trucks, especially medium and heavy trucks, have relatively high clutch pressure,
In order to reduce the force that the driver presses the clutch pedal,
Usually, a clutch booster, also known as a clutch booster cylinder or booster pump, is used,
This device uses both cylinders and cylinders.
What is the use of clutch booster cylinder
The clutch booster is used in cars with hydraulic operated clutch mechanisms. When the clutch is disengaged or engaged, this assembly is used to help increase output force. This assembly is installed between the clutch and the clutch master cylinder, without additional mechanical transmission components.
The working principle of clutch booster:
When the clutch pedal is pressed, hydraulic oil forms a certain amount of pressure in the clutch master cylinder and then enters the clutch booster. At this point, the hydraulic oil works in two steps in the booster. First, enter the hydraulic system of the clutch booster, where hydraulic oil acts on the hydraulic piston, which pushes the B rod forward. The left end of the hydraulic piston is sealed with a D-shaped rubber ring, and there are two hydraulic piston cups on the hydraulic piston to prevent oil leakage and sealing.
The other path flows to the clutch boost control valve system. When the hydraulic system is working, hydraulic oil pushes the relay valve. There are two cups on the piston of the relay valve, which not only withstand oil pressure but also serve as a seal. The piston of the relay valve moves to the left, overcoming the elasticity of the diaphragm return spring and the poppet valve spring. Close the exhaust port, open the lift valve, and the compressed air enters the power cylinder. Overcoming the force of the return spring of the power cylinder, it works with the A and B push rods to push the piston to the right. At this point, the combination of oil pressure and air pressure simultaneously serves as a boost. In the absence of compressed air in the car cylinder, the hydraulic system of the booster can also operate independently, but it is more laborious to operate.
The master cylinder and slave cylinder of the clutch are actually equivalent to two independent hydraulic cylinders. The master cylinder has inlet and outlet oil pipes, while the slave cylinder only has one. When the clutch is pressed, the pressure from the master cylinder passes through the slave cylinder, which starts working. Then, the release fork separates the clutch pressure plate and pressure plate from the flywheel, and gear shifting can begin. After releasing the clutch, the slave cylinder will stop working, and the clutch pressure plate and pressure plate will come into contact with the flywheel again. Power will continue to be transmitted, and the oil from the slave cylinder will return. In order to enable the driver to perceive the degree of clutch engagement and disengagement at any time, an increasing function is formed between the output force of the car's clutch pedal and the pneumatic booster. When the pneumatic power system fails, it can also ensure that the driver can manually operate the clutch.
