auto clutch booster, by definition, means may be provided to assist the clutch, helping drivers to pay to reduce the force, thereby reducing driving fatigue, ensure traffic safety.
1. The clutch booster structural features
Clutch pressure booster is provided in the hydraulic control mechanism, a common source of compressed air and pneumatic braking system and other pneumatic equipment. Which mainly consists of four parts air pressure control valves, hydraulic cylinders, the power piston, the housing and other components.
In order to enable the driver to perceive and control the degree of clutch disengagement or engagement at any time, the output pressure of the booster force to the clutch pedal stroke constant increment function. Further, when the air pressure booster system failure, but also to ensure via human manipulation of the clutch.
2. works
When the clutch pedal is depressed, the clutch pressure from the master cylinder by hydraulic fluid lumen tubing into the booster, as the pedal stroke increases, increasing the amount of oil entering the booster , and increased oil pressure, then the hydraulic oil pushes the piston stem and diaphragm assembly is shifted rightward, the end portion of the stem vent is blocked by the valve lift, the valve lift and open, so that compressed air from the air reservoir by the stem of the diaphragm assembly into the right chamber of the left chamber of the power piston 5, with the increased opening stroke of the poppet valve, the compressed air pushing the power piston, ram, hydraulic piston, a plunger and drive right rotating clutch release fork, the clutch release bearing pad ring pushing the lever forward, so that the clutch is disengaged.
When release the clutch pedal, hydraulic pressure is lowered, under the action of the spring disc is pressed, reverse thrust ram, the hydraulic piston, the power piston and the ram, compressed air diaphragm stem assembly to the left moving, under the action of the poppet valve return spring is closed, the compressed air and the diaphragm right chamber flows into the left chamber of the power piston diaphragm chamber through the left core rods vent into the atmosphere through the vent plug. Under the action of the push rod, a hydraulic piston return, the hydraulic oil flows into the clutch master cylinder trans.
