5.7.1. Device and operation of the transmission

Transfer of power on the leading shaft of the main transfer is carried out through two shaft with cogwheels: primary and secondary.

Fig. 5.15. Operation of the synchronized coupling: 1 — shlitsevy a gear wheel wreath; 2 — the conic blocking rings; 3 — an external ring of the coupling; 4 — a cracker; 5 — a sheet spring; 6 — a coupling nave; and — transfer is switched off (neutral situation); — transfer is included


The conducted clutch plate is established directly on vents of a main shaft. Cogwheels with the 1st on the 4th transfer are recorded on a shaft, the cogwheel of the 5th transfer rotates freely. At inclusion of the 5th transfer the cogwheel connects to shaft by means of the synchronized coupling 4 (fig. 5.15) of inclusion of the 5th transfer. The main shaft rotates in the roller bearing installed in a coupling case, and in the ball bearing installed in a transmission case.
The leading gear wheel and cogwheel of the 5th transfer are established on secondary to a shaft not movably. All other cogwheels rotate a main shaft, but when coupling is not involved, they are in the mode of free rotation. The cogwheel for the 5th transfer is established on secondary to a shaft by means of shlitsevy connection. Cogwheels with the 1st on the 4th transfer to time of inclusion of coupling connect to a secondary shaft by means of synchronized couplings. Couplings of inclusion 1-2, 3-4 transfers mobile, are in constant hooked with a secondary shaft by means of shlitsevy connection. The bearing of a secondary shaft located in a coupling case roller, and in a transmission case — ball.
Cogwheels and the mechanism of inclusion of the 5th transfer are located outside a transmission case, in a removable case.
The mechanism of gear shifting consists of synchronized couplings, forks and rods of gear shifting. The cogwheel of transfer of a backing is located on a shaft of turning on of the reverse gear.
The differential is located in a coupling case. The torque is transferred to the epycyclic (conducted) gear wheel from the leading gear wheel of the main transfer located on secondary to a transmission shaft. Leading and epycyclic gear wheels of the main transfer cylindrical. The differential consisting from a gear wheel of half shafts and satellites transfers rotation directly to half shafts of forward wheels via hinges of the equal angular speeds executed in the form of trekhshipovik (further CV JOINTS).
Synchronized couplings of gear shifting are used in KP to inclusion of torque transmission from a main shaft on secondary. The coupling consists from:

Fig. 5.16. An arrangement on a shaft of elements for greasing of the rubbing surfaces: 1 — a shaft;
2 — a gear wheel; And — lubricant flutes; B — the channel for greasing


— the nave of 6 (fig. 5.16) having internal vents which connect it not movably to a secondary shaft, and external vents on which the external ring of the coupling with internal vents can move;
— the external ring 3 couplings having the internal vents corresponding to external vents of a nave and shlitsevy wreaths of freely rotating gear wheels of the corresponding transfers and a ring flute for gearing with a gear shifting fork;
— the conic blocking rings 2 synchronizing (equalizing) the angular speed of rotation of a secondary shaft and freely rotating gear wheel of the chosen transfer;
— crackers 4 sprung by a sheet spring 5.
When switching transfer coupling is squeezed out, i.e. the bent shaft of the engine and main shaft KP are disconnected, therefore, a main shaft with the gear wheels of the first, second, third and fourth transfers recorded on it, and also the gear wheels of a secondary shaft corresponding to them rotate freely, irrespective of the speed of rotation of a bent shaft of the engine and wheels of the car.
Gear shifting rod fork, being in continuous gearing with an external ring 3 synchronized couplings, moving in the direction of a gear wheel of the corresponding transfer through an external ring 3, moves internal to vents a cracker 4 which presses the conic blocking ring 2 to a conic surface of the corresponding cogwheel, creating the increased friction in a contact zone that leads to alignment of angular speeds of a cogwheel and the synchronized coupling. The external ring of the coupling comes on shlitsevy a wreath of 1 gear wheel.
Thus, main and secondary shaft are connected and rotate with a frequency proportional to the transfer relation of the chosen transfer.
Greasing of freely rotating cogwheels which do not have bearings is carried out through the lubricant channels B and flutes executed in a shaft by 1 (fig. 5.16) And.

Fig. 5.17. Scheme of torque transmission by the transmission and main transfer: 1, 2, 3, 4, 5 — gear wheels of inclusion of the corresponding transfers; 6 — a gear wheel of inclusion of a backing.


Torque transmission via the transmission from a main shaft on a half shaft is schematically shown in fig. 5.17.
The direction of rotation of a secondary shaft changes on opposite by means of introduction to gearing of a cogwheel of the backing (a parasitic gear wheel) located on an ox of inclusion of a backing.
