The editors are grateful to SAE for disseminating outstanding German and European brake engineering knowledge to the worlds brake experts through this book. It contains
8、the Symposium contributions of the past 4 years covering important areas and aspects of modern brakes, their components and systems and their potentials and interactions with other basic disciplines (e. g. new materials) and automotive systems (e. g. intelligent chassis). We thereby hope to encourag

18、3 W. Steiger, Volkswagen AG1 1 Introduction Prof. Dr. B. Breuer, Dipl.-Ing. U. Dausend, Darmstadt University of Technology Darmstadt, Germany The technical purpose of brakes is to decelerate moving vehicles through the tire/road contact, to adapt their speed to traffic conditions, and to prevent the
19、ir involuntary movement once stopped. They transform kinetic energy into thermal energy for storage in the brakes, followed by dissipation to the surrounding air, and must be able to exert sizable torques to the wheels even at standstill. Peak power levels in emergency braking far exceed maximum eng
20、ine power. Appropriate brake force distribution to the wheels in keeping with road surface conditions (e.g. icy/dry) and braking stability (left/right and front/rear), adapted to the driving state of the vehicle (e.g. gradual speed change versus emergency braking), are vital for accident prevention.
21、 Customers are particularly interested in short stopping distances, ease of operation, prevention of fading and skidding, high braking comfort (actuation, noise and vibration) and long service intervals. Engineers must meet customer demands as well as strict regulatory and OEM specifications respect
22、ively for brake system safety and reliability, dimensions and packaging, comfort, maintenance, recycling and cost. Nineteenth century automobiles, essentially carriages without a drawbar, had correspondingly very simple brakes. With the advancement of automotive technology and increasing top speeds
23、in the early 20th century, engineers moved from braking the rear axle only to four-wheel systems and replaced mechanical brake actuation by hydraulic systems. The next steps with cars almost always2 ahead of commercial vehicles and motorcycles were disc brakes replacing drum brakes, the addition of
24、a second brake circuit, and antilock brake systems (ABS) first introduced in Mercedes-Benz cars in 1978. ABS allowed simultaneous braking and steering without skidding, making good automatic use of available tire/road friction, and represented a giant step forward in motor vehicle safety. Today, dri
