About this book

The aim of this work, consisting of 9 individual, self-contained booklets, is to describe commercial vehicle technology in a way that is clear, concise and illustrative. Compact and easy to understand, it provides an overview of the technology that goes into modern commercial vehicles.

Starting from the customer's fundamental requirements, the characteristics and systems that define the design of the vehicles are presented knowledgeably in a series of articles, each of which can be read and studied on their own. This volume, Transmissions and Drivetrain Design, begins with an explanation of how driving resistance and the engine characteristics factor into the configuration of the transmission and transmission ratios. The transmission and its associated assemblies are presented in detail, providing a clear understanding for training and practical applications. Other components of the drivetrain such as the propeller shaft, the clutch and the retarder are also discussed.

Table of Contents

Chapter 1. Transmissions and Drivetrain Design
The task of the transmission, clutch and propeller shaft is to transmit the mechanical motion of the engine to the axle and the wheels. These components also perform other essential functions. The motion of the engine must be converted.

Chapter 2. Transmission
Many different types of transmissions exist in motor vehicle construction. The torque can be converted hydraulically or mechanically. Hydraulic variants are usually associated with greater power loss than the mechanical ones.

Chapter 3. The Clutch
The clutch has the task of connecting and disconnecting the engine and the transmission (plus the drivetrain elements attached to the transmission). This ability to disconnect the engine from the rest of the drivetrain is essential to enable the engine to be started, gears to be changed in the transmission and to stop the vehicle. The clutch also smooths out the engine’s rotational irregularities and torsional vibrations.

Chapter 4. Propeller Shaft(s)
The function of the propeller shaft is to transmit torque between the transmission, the transfer case and the driving axles. The propeller shaft makes it possible to connect two axes of rotation which are not exactly in the same plane. Since the transmission and the axles move relative to each other as part of the suspension process, the propeller shaft must be able to balance out this relative movement.

Chapter 5. Retarders
Retarders are wear-free brakes that can be fitted in the vehicle besides the normal disc brake and the engine brake. The braking effect of the retarder depends on the rotating speed of the component that is to be braked: the faster this component is rotating, the more powerful the braking effect is.
