Coupling

General information

Assembly of coupling provides smooth perception of a torque from a flywheel of the engine and its transfer on primary shaft of a transmission, and also a rupture of a stream of capacity during the gear shifting moments.

On all equipped RKPP models one-disk coupling of dry type with a diafragmenny spring is used. The nave of a frictional (conducted) disk of coupling is equipped with the longitudinal shlitsa entering into gearing with shlitsa of a pin of primary shaft of a transmission. Frictional and press disks of coupling keep in contact with each other at the expense of the effort developed by a diafragmenny spring of a press disk.

Switching off of coupling is made in the hydraulic way. The drive of switching off consists of a pedal of the coupling connected to the GTTs tank (see. Head Brake system) the main hydraulic cylinder, connecting lines and the executive cylinder, by means of a fork of switching off of coupling connected to the vyzhimny bearing. When squeezing a pedal of coupling in a path of a hydraulic actuator pressure, resultants which influence rises is put by the external end of a fork of switching off. At turn the fork rests fingers in vyzhimny the bearing which, being displaced, nestles on petals of a diafragmenny spring of a press disk in assembly of a basket of coupling. Being curved, the spring deduces press and conducted disks from gearing, interrupting with that torque transfer from the engine to a transmission.

At coupling service, besides replacement of the components having obvious mechanical damages, it is necessary to make some primary checks (it is supposed that the transmission is in good repair):

  • First of all it is necessary to make check of level of liquid in the GTTs tank (see. Head Current leaving and service). In case of need execute the corresponding adjustment, having added demanded amount of more freshly hydraulic liquid of a demanded grade, and attentively examine system on existence of signs of leaks. At a devastation of the tank of the main cylinder it is necessary to remove from a hydraulic path air jams (see. The section Removal, service and installation of the executive cylinder of a drive of switching off of coupling) then to check serviceability of functioning of coupling;
  • For an assessment of time of switching of coupling start the engine on normal turns of idling. Make sure that neutral transfer is included and release a coupling pedal. Squeeze out a pedal and, having waited for some seconds, include a reverse gear, - switching should not be accompanied by a gnash and other extraneous noise, with high degree of probability indicating malfunction of a conducted disk or assembly of a basket of coupling;
  • For check of completeness of switching off of coupling cock the parking brake and start the engine. Holding a coupling pedal at height about 13 mm over a floor, попереключайте a box between the first and back transfers. Existence of hindrances when switching the lever speaks about malfunction of components of the mechanism of switching off. Estimate size of a course of a pusher of the executive cylinder of coupling, - at completely squeezed out pedal the pusher should be put forward on appreciable size, otherwise it is necessary to check level of hydraulic liquid in the GTTs tank;
  • Make visual check of a condition of axial plugs in the top part of a pedal of coupling. Make sure of lack of signs of jamming and excessive люфта axes;
  • From under the car check reliability of fixing of a fork of switching off of coupling on a finger of a spherical support.
