External components of automatic transmission

1 – картер the hydrotransformer, 2 – main картер, 3 – a face cover, 4 – the pallet, 5 – a pipe щупа for measurement of level of oil, 6 – щуп for measurement of level of oil, 7 – the heat exchanger, 8 – a cable of compulsory inclusion of a hill-climbing gear, 9 – сапун, 10 – the switch of a starter / of a lantern of a backing,

11 – the lever of the selector, 12 – an eye, 13 – a drive of a speedometer, 14 – the left exit of a transmission, 15 – the right exit of a transmission, 16 – a drain stopper, 17 – the hydrotransformer, 18 – bolts of the bearing of a conducted shaft, 19 – a regulator of a tape of a brake, 20 – check of pressure, 21 – a drain stopper

The drive consists of following knots: hydrokinetic transfer, a transmission, a centrifugal regulator.

Hydrokinetic transfer consists of the pump, the turbine and the directing device.

Into transmission structure, first of all, enter:

 – The planetary transfer, allowing to receive four transfers for advance and one transfer of a backing;
 – The hydraulic operating servomotor providing automatic control by a gear change;
 – шестеренчатый the oil pump constantly put in action by the pump of hydrokinetic transfer, the feeding hydraulic managing director сервонасос and hydrokinetic transfer, and also providing greasing of planetary transfer; restriction of the maximum pressure provides переливной the valve.

The centrifugal regulator is put in action by intermediate shaft; directly under the influence of turns of resulted wheels centrifugal force influences on грузики which change a signal of speed to a pressure signal through дросселирование a stream: this pressure "is analyzed" in the operating servomotor and defines a gear change.

The kinematic scheme of an automatic transmission


The transmission contains:

 – Planetary transfer;
 – Three multidisk couplings (And, In and), everyone operated the hydraulic piston;
 – Three unidirectional couplings (F, G and);
 – One tooth gearing on an exit of the planetary transfer, transferring draught on an intermediate shaft (2) which puts in action differential (3);
 – Hydrokinetic transfer (4) on an input of the transmission providing connection of the engine with a transmission;
 – The main transfer and differential.

The knot of mechanical elements copes the hydraulic servomotor located in the bottom part of a transmission.
