The clutch
The clutch serves to transmit torque from engine, short of disconnecting the engine from transmission and their smooth connection at the switches the research Institute of transmission and starting the car. Consists of the clutch mechanism and drive him off learning from. The most widespread single-disc the clutch is friction type . The main item- mi clutch driven disk are fixed- tion on the master wheel gearbox, push (am- schy) a disk with springs that are fixedly attached to the mA- the høvik crankshaft of the engine. The principle of operation of the clutch mechanism based on IP- the use of the frictional forces of the connecting surfaces. Drives compressed springs leading (pressure) drive, in a result of between them the friction spinning- schy is transmitted from the crankshaft of the engine to the ve- future shaft of the gearbox. Master and slave drives clutch is constantly pressed by springs to each other and open only for a short time under the influence the drive clutch when changing gear or braking of the car. The smoothness of the inclusion of the coupling- tion is provided by slippage drives up to the moment of pressing them to each other. Casing coupling from stamped steel and is attached to the flywheel bolts. Inside the housing are arranged levers off the outer ends of which pivotally connect HN with the pressure plate. The drive may move around relation to the housing, rotates together with the flywheel. Inter- Doo the leading disk and the housing along the circumference location HN / push coil springs, clamping ve my accounts have been leading the disc between the disc and the flywheel. Vedo- my steel disc with friction pads of asbes- the color of plastic is connected with the hub damper, the balance weight on inner side governmental hesitation. Torsional oscillations occur on the flywheel. - La due to the cyclical nature of his work. When the clutch they are transferred to the slave disk, forcing it to rotate relative to the hub. When this occurs the friction disc on the hub flange, and torsion energy Ko vibrations dampened, turning into the warmth. In General, the extinguisher torsional vibrations contributes to the smooth inclusion adhesion, increases durability of the parts boxes to re- houses and propeller shaft. The mechanism of the clutch with two driven disks di- is from single-disc friction clutch the presence of secondary pressure plate that is located between do two driven discs. Schematic design- the news of differences of elements from a single disc double disc the mechanism of adhesion has not. Single-disc clutch mechanism with Central dia- fragmani by a compression spring has only one compression spring, made in the form of a bowl equipped with Noah 18 petals that are not only elastic elements, but at the same time and pull levers. When the clutch thrust bearing pressure who acts on the petals of the spring and moves it to the side of the flywheel. The outer edge of the spring is bent in reverse side latches and withdraws the pressure plate from the slave. Mechanical drive clutch the most simple in design and convenient in operation. Used on most domestic trucks- mobiles. Mechanical drive clutch consists of: • pedal; • return spring; • roller arm; • thrust; • the lever of a plug of deenergizing of coupling; • fork; • clutch thrust ball bearing; • the release springs. By pressing the pedal all the drive components come into com- modestie, resulting in thrust bearing clutch presses on the inner end of the lever off, on- body disc is discharged, and the slave is freed from Wuxi Leah clamping springs and the clutch shall be disengaged. When you switch on the clutch pedal is released, clutch with thrust bearing takes the initial position, OS- Vologda levers off, leading the drive for action- eat spring presses the driven disk to the flywheel and drainpipe coupling. - tion is switched on. |
