Coupling

The general data

Coupling assemblage provides smooth perception of a twisting moment from a flywheel of the engine and its transfer on a primary shaft of a transmission, and also rupture of a stream of capacity during the gear change moments.

On all equipped Manual transmission models one-disk coupling of dry type with диафрагменной a spring is used. The nave of a frictional (conducted) disk of coupling is equipped longitudinal шлицами, entering into gearing with шлицами pins of a primary shaft of a transmission. Frictional and press coupling disks are kept in contact with each other at the expense of the effort developed диафрагменной by a spring of a press disk.

Coupling deenergizing is made in the hydraulic way. The deenergizing drive consists of a pedal of the coupling connected to tank GTTS (the Brake system see the Head) main hydraulic cylinder, connecting lines and executive cylinder, by means of a plug of deenergizing of coupling connected with выжимным the bearing. At squeezing of a pedal of coupling in a hydrodrive path pressure rises, результирующее which influence is put to the external end of a plug of deenergizing. At turn the plug rests fingers in выжимной the bearing which, being displaced, nestles on petals диафрагменной springs of a press disk in assemblage of a basket of coupling. Being curved, the spring deduces press and conducted disks from gearing, interrupting with that transfer of a twisting moment 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 a liquid in tank GTTS (Current leaving and service see the Head). In case of need execute corresponding updating, having added demanded quantity of a fresh hydraulic liquid of a demanded grade, and attentively examine system on presence of signs of leaks. At a devastation of the tank of the main cylinder it is necessary to remove air stoppers (see Has undressed Removal, service and installation of the executive cylinder of a drive of deenergizing of coupling) from a hydraulic path, then to check up serviceability of functioning of coupling; For an estimation 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 specifying in malfunction of a conducted disk or assemblage of a basket of coupling; For check of completeness of deenergizing of coupling cock a lay brake and start the engine. Keeping a coupling pedal at height about 13 mm over a floor, попереключайте a box between the first and back transfers. Presence of hindrances at lever switching speaks about malfunction of components of the mechanism of deenergizing. 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 up level of a hydraulic liquid in tank GTTS; Make visual check of a condition of axial plugs in the top part of a pedal of coupling. Make sure of absence of signs of jamming and excessive люфта axes; From under the car check up reliability of fixing of a plug of deenergizing of coupling on a finger of a spherical support.
