The Three Important Roles Of The Clutch Plate
The clutch plate can turn.
The role of the clutch plate and the driven plate is to transmit the power of the engine to the gearbox when the combination is combined. Friction plate, also known as clutch plate, because in the clutch, by friction clutch and clutch or clutch, is an important part of the clutch.
The clutch plate has three important effects: power transmission; Clutch Disc power cut off; to prevent overload.
The clutch plate is mounted on the flywheel of the engine and rotates with the engine. The driven plate (that is, the friction plate) is splined with the spline of the gearbox input shaft through the spline groove. When the friction plate rotates, the gearbox input shaft rotates When the pressure plate in the role of the spring, the pressure on the drive plate, the drive power; when the pressure plate in the depression under the clutch pedal, Clutch Disc the pressure plate back, the drive plate will not have the force, that is, separated state; Light step on the clutch, the pressure plate spring does not have all the role, which is half-clutch, also called semi-linkage.
Clutch disc is the most important thing is composed of three things, namely, "cover", "disk", "separation rod and spring."
Cover is generally two: one is stamping parts, one is casting.
"Disk" of course is to press the clutch plate with, and need it to clutch with the clutch surface friction.
"Separation rod and spring" is divided into two forms, one is the traditional coil spring, one is the diaphragm spring. The coil spring needs to work with the separation lever, and the diaphragm spring itself is both a spring and a lever.
Clutch discs are an important structure on the clutch, and its role plays an important role in car safety. The clutch plate is one of the most important components of the clutch assembly, Clutch Disc and transmits and cuts off the power transmission of the engine through the linkage mechanism according to the driver's wishes. And with the clutch chip with the smooth start of the vehicle, smooth gear and prevent the engine overload. ,
Clutch disc brakes are widely used with spring-loaded friction clutches (referred to as friction clutches). The torque generated by the engine, through the flywheel and pressure plate and the driven plate of the friction surface, passed to the driven plate. When the driver depresses the clutch pedal, the large end of the diaphragm spring is driven by the transmission of the machine, Clutch Disc and the driven part is separated from the active part.
The clutch plate has a friction plate, like the brake pads on the wheel, is very wearable asbestos and copper wire, the pressure plate friction plate also has the minimum thickness allowed, Clutch Disc the mileage is long, the pressure on the pressure plate The film should be replaced. The original friction plate replacement can buy spare parts to replace their own, and now are already installed to buy a friction plate pressure plate sub-assembly, do not have their own friction plate, and directly for the clutch plate on it. In order to reduce the loss of the clutch plate, there is a correct way to use the clutch pedal. It is not half step on the clutch pedal. So that the clutch plate is in a semi-clutch state, that is, Frisbee and pressure plate in the state of friction. If the clutch pedal is fully depressed, the flywheel and clutch discs are completely cut and there is no friction between the two. Clutch Disc If the clutch pedal is fully lifted, the flywheel and the clutch plate are fully engaged, although there is friction, but there is still no friction. So that the clutch pedal can not be pressed to half the state.
So how is the clutch plate overhaul? Clutch disc repair methods and requirements are as follows:
1) Clutch plate face plane error should not be greater than 0.12mm, the groove depth should not be greater than 0.50mm, too deep, should be grinding on the surface grinding machine, but the grinding thickness should not be greater than 1mm. If the size of the grinding thickness has arrived, there is still a small amount of plane is not polished, as long as the unmasked area is not greater than 10%, and the distribution is uniform, can continue to use.
2) pressure plate grinding should be carried out after the balance test, the imbalance error should not be greater than 50g.cm. If the tolerance is too much, you can use the drilling method in the appropriate part of the pressure plate drilling, so that the balance to meet the requirements.
3) The gap between the drive pin hole and the drive pin of the medium pressure plate with the two-piece clutch should be no more than 1mm, and the drive pin can be changed to 90 °. Otherwise it should be with repair or replacement.
4) If the pressure plate has a serious aging, cracking phenomenon, Clutch Disc and wear groove depth greater than 0.50mm above, should be replaced with new pieces.
