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, Chassis and Axles, explains the support structure of the vehicle, the chassis, and its attachments. The suspension and the steering are explained as well as the axles and tires. The reader thus gains a basic understanding of the rolling understructure of the commercial vehicle.

Table of Contents

Chapter 1. Chassis/Frames
The chassis is the basic structure of the vehicle. In a narrower sense, the chassis is only the support structure of the vehicle. In vehicle technology, though, what is often meant by the chassis is actually the frame (i.e. the support structure) complete with the suspension, steering and attachments that are directly fastened to the frame.

Chapter 2. Suspension
The wheel suspension connects the wheels and axles with the frame and the superstructure. On the one hand a stiff and well-defined connection is required to allow for safe driving. On the other hand the suspension is designed to filter and dampen road bumps und uneven roads in order to improve comfort for the driver and reducing stresses on the vehicle body and on the cargo.

Chapter 3. Steering
The task of the steering system is to enable the driver to change direction as needed. In Europe, regulations that a steering system for commercial vehicles (and also the steering system of other road vehicles) must meet are set out in ECE-R 79. This regulation does not apply in North America.

Chapter 4. Other Attachments
As already mentioned in Sect. 1.2, many components are fastened to the frame along with the large assemblies, such as the cab, body, axles and drivetrain (that get their own booklets in this series). Cab, body and fifth wheel, in the case of a tractor, are sitting on top of the frame. Most other attachments to the frame are mounted sideways. Fig. 4.1 shows some example of attachments to the frame.

Chapter 5. Axles
The axle performs numerous fundamental functions in the vehicle. The typical functions of axles are:
  • Support
  • Spring suspension
  • Rolling
  • Braking
  • Steering
  • Driving

Chapter 6. Tires
According to Michael Schumacher, in Formula 1 motor racing the tire is the component that most frequently decides whether a race will be won or lost. In the commercial vehicle business, although it is not a matter of winning or losing, the tire is pretty important for the performance of the vehicle.
