9. Coupling9.1. Introduction
Coupling On cars from a manual transmission dry, one-disk coupling with a diafragmenny press spring and a hydraulic actuator is established. Depending on a design of the established flywheel in coupling 2 types of frictional disks are used. On a usual flat flywheel frictional disks with buffer and dempferny springs are established. Buffer springs are built in between frictional sections and intended for smoother inclusion of coupling. Dempfernye springs (quenchers of krutilny fluctuations, are strengthened on a disk nave) smooth the strong pulsations arising because of sharp changes of frequency of rotation of the crankshaft. On a dual flywheel dempferny springs are built in in a flywheel. Driveshaft The driveshaft two-section, with an average support and sliding shlitsevy connection, connects a back axis with a check point via 2 kardanny hinges. The shaft is connected to transmission via the elastic coupling. On a part of cars between a flange of a shaft of a check point and the coupling the quencher of fluctuations is established. The forward part of a shaft is aligned with a check point flange by means of the plug. Main transfer The main transfer consists of differential (includes leading and ring conducted gear wheels and also differential gear wheels) and flanges to which via CV JOINTS semi-axes fasten. Repair of differential is carried out only in car-care center. Semi-axes and CV JOINTS On each of semi-axes it is established on 2 CV JOINTS. The internal CV JOINT fastens to differential flanges bolts, the external CV JOINT fastens on a nave of a back wheel a nut, navernuty on the carving termination of a shlitsevy part. CV JOINTS are filled with special greasing and closed by the covers which condition should be checked periodically. The external CV JOINT changes complete with a semi-axis. |
