Coupling is intended for a rupture of power communication between the engine and RKPP when switching transfer and provides thanks to frictional communication smooth transfer of a torque on a running gear at a start of motion.
Coupling consists of the press disk, a conducted disk, and a hydraulic drive with the main thing and the executive cylinder.
Conducted and press disks, and also the executive cylinder of coupling
Press the disk bolts fastens to a flywheel connected with cranked shaft of the engine. Between a press disk and a flywheel there is a conducted disk which nestles on a flywheel the press bearing of the executive cylinder. The conducted disk is connected with primary shaft of RKPP through shlitsevy connection.
By pressing of a pedal of coupling brake liquid from the general tank via the main cylinder of coupling under pressure is transferred in the executive cylinder. Press the bearing of the executive cylinder influences on press a disk. Thus conducted disk is taken away from a flywheel and power communication between the engine and RKPP interrupts. In not pressed condition the press spring presses the bearing to a tarelchaty spring of a press disk. It reduces wear of the press bearing of coupling since it at inclusion is not dispersed to number of turns of the engine.
At each inclusion and coupling switching off as a result of power influence there is a wear of frictional overlays of a conducted disk. The conducted disk represents a wearing-out detail, however average term of its service quite big and depends generally on loading (operation with the trailer) and style of driving.
Saab 9-5 cars have a forward drive. The torque is transferred to wheels from transmission through the differential built in it by means of power shafts. Power shafts have identical length, however between the right shaft and differential the intermediate shaft leaning on the bearing, established on the power unit is established. The variable tilt angle of power shafts is carried out by means of internal and external hinges of the equal angular speeds (CV JOINTS) placed in protective covers. The internal hinge of the left shaft is fixed in a box with the help of a lock ring. The internal hinge of the right shaft is established in specially intended nest of an intermediate shaft. External hinges of both shaft enter into naves of forward wheels and are fixed by stupichny nuts.
