CLUTCH SYSTEM OF A BUS FOR PREVENTING REDUCTION OF OPERATING FEELING AND THE INCREASE OF PEDAL EFFORTS BY REMOVING OPERATING FEELING TRANSMISSION DIFFERENCE BETWEEN OIL AND THE AIR ALTHOUGH A DRIVER URGENTLY OPERATES A PEDAL IN AN INSTANT

摘要

PURPOSE: A clutch system of a bus is provided to prevent the increase of pedal efforts by filling a booster with high-pressure air all the time and removing time lag between oil and the air although a driver steps on a brake pedal in a short time by making action time of the air fast. CONSTITUTION: A clutch system of a bus is composed of a booster(5) and an air line. The booster comprises an oil operating unit connected with an oil line(4) extended from a master cylinder(3) pressurizing oil inserted from a reservoir tank(2) according to an operation of a clutch pedal(1) to open or shut an air flow passage and an air operating unit actuated by high-pressure air inserted through the air flow passage opened by the oil operating unit to actuate the air operating unit. The air line comprises an air supply line(7) for connecting a brake air tank(6) and the booster; an air moving line(7') for inducing the high-pressure compressed air filled in the booster through the air supply line toward the air flow passage formed at the oil operating unit; and an air inducing line(7") for inserting the high-pressure compressed air through the air moving line to the air operating unit and operating a clutch(8) by driving the booster.
