Introduction

The modular system

Individual modules are assembled in modular form. This increases their functionality after assembly in series production and in the service workshop.

The modules are:

Clutch release lever

This module contains the clutch release lever, the release bearing and the guide sleeve.

Selector shaft with selector mechanism cover

All blocking detent, spring and guide elements of the selector mechanism, as well as the angle piece for adjustment of the selector mechanism are accommodated in this module.

The inner selector module

with shift forks, selector plates and bearing.

The bearing support

with the two grooved ball bearings and pre-assembled powertrain and output shaft.

The housing

is made from magnesium and consists of 2 parts (gearbox housing, clutch housing). The gearbox housing is sealed off from the exterior by a cover.

The fixing points for the left assembly mounting bracket are located at the top of the gearbox housing. The attachment points for the self-aligning bearing support are located at the bottom of the gearbox housing.

In comparison with aluminium, magnesium has a lower density and therefore also lower strength. This was compensated for by thicker ribbing and increased wall thickness.

The result is a mass reduction of 2.5 kg compared to the conventional aluminium construction.
