Coupling The general data Flywheel, basket and coupling disk On considered models one-disk dry coupling with диафрагменной a spring is established. Coupling consists of a basket with the press disk, a conducted disk, the bearing of deenergizing of coupling and a hydraulic drive. The coupling basket is connected by bolts to a flywheel which is in turn fixed on cranked to an engine shaft. Between a press disk and a flywheel there is a conducted disk of coupling which nestles on a flywheel a press disk. The conducted disk of coupling is connected through шлицевое connection with primary shaft of a transmission. By pressing of a pedal of coupling by means of a hydrodrive the bearing of deenergizing of coupling presses a spring of a press disk. Press the disk and a conducted disk thus unloads does not nestle any more on a flywheel. Power communication between the engine and transmission interrupts. Coupling of all models with РКПП has a hydraulic drive. A working liquid is the brake liquid which arrives from the general tank of a brake liquid. At each inclusion and deenergizing of coupling owing to a friction there is a deterioration of frictional overlays of a conducted disk. The conducted disk is a wearing out element of coupling. Its average service life makes over 100 000 km. Speed of deterioration depends on loading (movement with the trailer) and a management style the car. Coupling does not demand service, since. It self-established. The majority of engines is equipped by a two-mass flywheel. Such flywheel has pruzhinno-dempfirujushchuju the system, allowing to extinguish крутильные the fluctuations arising at work of the engine. Besides, the noise level on low turns thus decreases. The coupling disk at such flywheel consists of a nave, a conducted payment and frictional overlays. Dempfirujushchie springs are not established. |
