Basic function of all-wheel drive with automatic transmission

Overview

This document contains information on:

General

Function

General

The all-wheel drive for automatic transmission consists essentially of the following component parts:

Transfer case with front axle transmission output

Front axle transmission

Rear axle gear

Function

The automatically controlled all-wheel drive is a permanent all-wheel drive with interaxle differential.

The transfer case is flange-mounted to the automatic transmission or integrated into the automatic transmission. The basic locking torque of 50 Nm serves to improve traction at low engine torque and reduce driveline vibration.

Depending on the transfer case, a distinction is made between a fixed and variable drive torque distribution.

The fixed drive torque distribution is 50 % at the front axle and 50 % at the rear axle. The drive torque is distributed via a single-speed transfer case without off-road ratio to the drive axles (drive train).

Variable transfer cases enable drive torque shifting of 0-100 % between the axles.
