Hotel & Travel Information

Attendees to the seminars held in conjunction with the SAE 2015 World Congress will receive COMPLETE access to Congress activities for only $55 per day. If interested, please contact our Customer Service department at +1.877.606.7323 (U.S. and Canada only) or +1.724.776.4970 (outside U.S. and Canada) to register for this special Congress daily rate.

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 "A Familiarization of Drivetrain Components" seminar (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.

Joe Palazzolo is Chief Engineer – eDrive Systems at GKN Driveline. He is responsible for managing the mechanical design and development of new automotive gearboxes, torque transfer devices, concepts, and industrialization into production applications. His prior professional experience spans the majority of vehicle powertrain systems, including overall chassis design and validation, all-wheel systems design and development, power transfer unit and transfer case design, and torque management device development. Joe has been privileged to contribute while working at Carron and Company, Visteon Corporation, Warn Industries, Magna Powertrain, and Ford Motor Company.

Mr. Palazzolo maintains the ASE certified Master Technician and Undercar Specialist certifications, has chaired the SAE All-Wheel Drive Standards Committee, and has been an active SAE member since 1990. Mr. Palazzolo was a recipient of the SAE Forest R. McFarland Award for distinction in professional development and education in 2007. In 2010, he achieved the SAE Master Instructor designation and continues to maintain this in his three seminars that he has been teaching globally since 1999. In 2013, his technical and professional accomplishments to the industry were recognized by reaching the membership grade of SAE Fellow.

Mr. Palazzolo is the award winning author of High-Performance Differentials, Axles & Drivelines in 2009. In 2013, he furthered his authoring with his second text on How to Rebuild the Ford 8.8 and 9 inch Axles. He has just finalized three chapters to be featured in the Automotive Engineering Encyclopedia to be released in 2014. He has designed, built, campaigned and supported various race cars and teams for both professional and amateur racing organizations. His scope of work has been inclusive of the entire vehicle but also focused on competitive, high-performance drivetrain systems. He holds a Bachelors degree in Mechanical Engineering from Cleveland State University and a Masters degree in Automotive Engineering from Lawrence Technological University. He has received numerous patents for his work and creativity in advancing mobility systems.
