POWER AND PROPULSION
Fundamentals of Automotive All-Wheel Drive Systems 1 Day | Classroom Seminar I.D.# C0305 This seminar provides an introduction to the fundamental concepts and evolution of passenger car and light truck 4x4/ all-wheel drive (AWD) systems including the nomenclature utilized to describe these systems. Basic power transfer unit and transfer case design parameters, component application to system function, the future of AWD systems, and emerging technologies that may enable future systems are covered. This course is an excellent follow-up to the seminar, A Familiar- ization of Drivetrain Components (ID# 98028), which is designed for those who have limited experience with the total drivetrain. Learning Objectives By attending this seminar, you will be able to: • Identify front wheel drive and rear wheel drive vehicle architectures • Identify part time, full time, and on demand all-wheel drive systems • Explain the benefits of all-wheel drive over two-wheel drive • Quantify all wheel drive traction and mobility benefits • Describe auxiliary axle disconnect systems • Explain basic vehicle dynamics performance and the effect of AWD on performance • Identify couplers vs. biasing devices and their basic function • Describe the differences between mechanical and electrical implementation in AWD systems • Describe basic control strategies and logic • Discuss advanced propulsion concepts and systems Who Should Attend This seminar is designed for engineers (working with passenger cars, light trucks, and SUVs) who need to master AWD componentry, and the function and effect of those components. Engineers new to the 4WD/AWD field, as well as managers, marketing personnel, purchasing professionals and others interested in all-wheel drive fundamentals will benefit from this seminar. Prerequisites A technical background in any discipline is beneficial, although not required. This classroom seminar is equivalent to the On Demand Course, Fundamentals of Automotive All-Wheel Drive Systems. (ID# PD730556)
variable technologies −− Pros and cons of each • Comparison of “Stepped” vs. “Stepless” Transmission Technology
−− A brief review of transmission technology evolution −− Benefits and drawbacks of two modes of operation
• Concept of “friction required” transmissions (i.e. belt / chain CVT, Toroid, etc.) versus “friction not required” technology (i.e. gears, etc.) • Conceptual and functional differences between mechanical power transmission systems that require friction to operate and those that do not SESSION TWO • Vehicle Powertrain Optimization Example • The systemic effect of stepped versus stepless power transmission powertrain performance • Develop a model of the theoretical optimum functional requirement of a transmission SESSION THREE • Technology overview of belt style CVT (i.e. push / pull) and requirements of lubricant (CVT oil) • The specifics of a belt style CVT; most commonly based on a “push” belt technology, and the requirements of the lubricant to support expected performance levels • Technology overview of chain style CVT (i.e. pull) −− The specifics of a chain style CVT, most commonly based on a “pull” belt technology −− The requirements of the lubricant to support expected performance levels SESSION FOUR • Technology overview of toroidal style CVT and the requirements of the lubricant (traction oil) −− Specifics of a toroidal style CVT, most commonly based on a “bell” idler engaged with a set of toroids −− Requirements of the lubricant to support expected performance levels • Technology overview of sphere style CVT −− The specifics of a toroidal style CVT, most commonly based on a spherical planet (e.g. planet pinion gear of an epicyclic gear set) engaged with a set of conical races −− Requirements of the lubricant to support expected performance levels
