2017 The Tiguan 7 Speed Double Clutch Gearbox 0AM Service Training

Self-study Programme 390 The 7-speed Double-clutch Gearbox 0AM

Design and Function

The new 7-speed double-clutch gearbox from Volkswagen

The 7-speed double-clutch gearbox OAM is a further development of the very successful direct-shift gearbox 02E from Volkswagen.

In terms of comfort and shifting without interrupting drive, it offers the same as the direct-shift gearbox 02E.

It has been designed for engines with a torque of up to 250 Nm in the Polo, Golf, Passat and Touran.

Whilst the direct-shift gearbox is on a par with vehicles with manual gearbox in terms of fuel consumption, the double-clutch gearbox has succeeded in reducing fuel consumption below that of manual gearboxes by means of certain technical innovations in the gearbox.

This reduction in fuel consumption makes a significant contribution towards lowering emissions and safeguarding the environment.

In this self-study programme, you can find out how the new double-clutch gearbox functions and which technical highlights have helped to reduce fuel consumption.

We hope you enjoy reading it.

Introduction

With the new double-clutch gearbox OAM, Volkswagen is presenting two world premieres:

• The first 7-speed mounting transversely at the front and
• The first gearbox with dry double clutch guarantee

As a design feature, the dry double clutch has an extensive impact on the entire gearbox concept. In comparison with the direct-shift gearbox 02E, efficiency has once again been considerably improved thanks to the new gearbox concept.

This improved efficiency makes a significant contribution towards lowering consumption and emissions.

The 7-speed double-clutch gearbox OAM is a further milestone in the Volkswagen Group's gearbox strategy, and therefore extends Volkswagen's technological advantage still further.

Design features

• Modular design of the gearbox: The clutch, mechatronic unit and gearbox each form one unit
• Dry double clutch
• 7 gears on 4 shafts
• Separate oil circuit, mechatronic unit and mechanical gearbox, with lifetime fillings
• Oil pump driven subject to requirements
• No oil/water heat exchanger

Selector lever

Actuation

The selector lever is actuated as in vehicles with automatic gearboxes. The double-clutch gearbox also offers the option of shifting using Tiptronic.

Precisely as in vehicles with automatic gearboxes, the selector lever is equipped with a selector lever lock and an ignition key withdrawal lock. The lock functions as before. The design is new.

Design of the selector lever

Selector lever E313

Hall senders in the selector lever mounting register the position of the selector lever and make it available to the mechatronic unit via the CAN bus.

Selector lever lock solenoid N110

The solenoid locks the selector lever in the "P" and "N" positions. The solenoid is controlled by the selector lever sensors control unit J587.

Selector lever locked in position P switch F319

If the selector lever is in the "P" position, the switch transmits the signal - selector lever in "P" position to the steering column electronics control unit J527. The control unit requires this signal to control the ignition key withdrawal lock.

How it works:

Selector lever locked in "P" position

If the selector lever is set to "P", the locking pin is located in locking pin latch "P". This prevents the locking lever from being moved unintentionally.

Selector lever released:

After switching on the ignition and actuating the foot brake, the selector lever sensors control unit J587 supply the selector lever lock solenoid N110 with current. As a result of this, the locking pin is withdrawn from the locking pin latch "P".
