7.3.1. Introduction

THE GENERAL DATA

The four-stage automatic transmission with electronic control consists of the hydrotransformer, эпициклической a tooth gearing and гидравлически operated coupling and brakes.

The twisting moment from the engine to a transmission is transferred through the hydrotransformer which carries out function of liquid coupling and operates as automatic coupling. Also provides twisting moment transfer at acceleration.

The tooth gearing provides advance on one of 4 transfers or movement by a backing. Tooth gearing components cope brakes and муфтами couplings which is put in action гидравлически. The pump located in a transmission, provides necessary hydraulic pressure for work of a brake and муфты couplings.

Management of a transmission is made by the lever of the selector having 7 positions. Position D provides an automatic choice of transfers from 4 forward transfers. The automatic mechanism of fall of transfers switches transfer to the lowest if the accelerator pedal is pressed against the stop. This mode is necessary for using, when the maximum acceleration of the car is required. If the selector lever is in position 3, the car will move only on first three transfers, and in position 2 only on first two transfers etc. Installation of lower transfers is desirable at braking by the engine, at movement from biases or for prevention of an undesirable choice of the higher transfer on twisting roads.

Because of complexity of an automatic transmission, any repair should be made at servicing deport.
