Über dieses Buch

Despite the assistance provided by electronic control systems, the latest generation of passenger car chassis still relies heavily on conventional chassis elements. This book examines these conventional elements and their interactions with mechatronic systems within the context of driving dynamics. Chassis fundamentals and design are described in the initial chapters, followed by a practical examination of driving dynamics and detailed descriptions and explanations of modern chassis components. A separate section is devoted to axles and the processes used during axle development. This first English edition features a number of improvements over the latest German edition, including revised illustrations and several updates in the text and list of references.

Introduction – Fundamentals – Driving Dynamics – Chassis Components – Axles– Driving Comfort: Noise Vibration, Harshness (NVH) – Chassis Development –Chassis Innovations – Future Aspects of Chassis Technology

Chassis developers, automotive engineers in the subcontracting and supplier industries, vehicle testing engineers, vehicle assessors and evaluators, chassis experts in vehicle workshops, professors and students at universities and technical colleges.

1. Introduction and Fundamentals
Abstract
When specialists discuss motor vehicle technology, topics such as mobility, power, efficiency, vehicle classification, chassis, safety, ride comfort, dynamics, and environmental concerns are all frequently mentioned. Electrical systems and electronics are also topics which are discussed with increasing frequency. Active systems, X-by-wire, driver assistance systems, control systems, hybrid drive, vehicle agility, and infotainment are all areas of current importance.

2. Driving Dynamics
Abstract
The dynamic analysis of motor vehicles is typically divided into three domains corresponding to the vehicle's three translational degrees of freedom (Figure 1-15).

3. Chassis Components
Abstract
The majority of this book is dedicated to chassis components. These components consist of chassis subsystems as well as the modules and parts contained in these subsystems. Chassis components and systems can be classified according to function or divided into groups or modules. The resulting organizational structures often overlap with one another.

4. Axles and Suspensions
Abstract
Axles were originally defined as rigid lateral connections between two wheels which could be steered together. This type of axle helps ensure rolling stability and simplifies assembly by providing a connection between the wheels and body. This axle definition is valid for all rigid and semi-rigid axles. Such designs feature wheels that are attached directly to the axle. This type of axle follows the motion of the wheels at all times. The direct connection between the wheels was eliminated with the introduction of independent suspension systems, which feature wheels that are mounted to a steerable wheel carrier. This wheel carrier is part of a kinematic linkage which connects the wheel to the axle. The term “axle” is less easily defined for these systems. In some cases, the axle is defined as the entire system, including the independent suspension and wheel carrier. In other instances, the new components (suspension linkage and wheel carrier) are considered a separate assembly (known in North America as a “corner module”) in addition to the axle and subframe. This book will use the latter definition, as the former is based on the concept of rigid axles, which are increasingly irrelevant for passenger vehicle design.

5. Ride Comfort and NVH
Abstract
Ride comfort is defined as the overall comfort and well-being of the vehicle’s occupants during vehicle travel. The main sources of discomfort are oscillations which reach the vehicle’s passenger compartment and cause noise, vibration, or both. Since the sources of these oscillations (the roadway, chassis, and powertrain) are outside of the passenger compartment, specially-designed components can be used to hinder the transmission and penetration of disturbances into the passenger compartment.

6. Chassis Development
Abstract
The chassis development process is characterized by large production volumes (100,000 to several million units over the entire production run), sophisticated technologies, strict safety and environmental regulations, and time and cost pressures.

7. Chassis Control Systems
Abstract
Electrical and electronic systems and components currently represent about 20% of the total added value of modern vehicles. Premium-class vehicles can feature up to 70 electronic control units (ECUs). The electronic content of passenger vehicles is expected to increase to as much as 40% of the total added value by the year 2015. This dramatic increase raises an important question: what advantages do chassis electronics offer the driver?

8. The Future of Chassis Technology
Abstract
Increases in the standard of living and wealth of society as a whole have led to greater expectations for both comfort and enjoyment as well as an increased desire for protection and safety. These increased expectations and desires are present in all aspects of daily life. The automobile, as an unavoidable component of individual mobility, is no exception. The needs and desires of modern society have greatly affected both chassis technology and vehicle control systems. The goal of vehicle control systems is to improve vehicle safety by giving the driver more control during nonlinear, combined maneuvers that may ordinarily be difficult or impossible to master.
