Who Should Attend?
This seminar is intended for engineers now working with passenger car, sport utility, truck, bus, industrial, and off-highway vehicles who have had minimal prior experience with the total drivetrain
Full Seminar Description
An efficient, robust, and quiet running drivetrain is as essential to customer satisfaction as styling and interior creature comforts. In this seminar, you will be exposed to various methods that can be used to accomplish this goal. Designed to help you visualize both individual components and the entire drivetrain system - without reference to complicated equations - this seminar focuses on the terms, functions, nomenclature, operating characteristics and effect on vehicle performance for each of the drivetrain components. Attendees will receive an introduction to the various components of the drivetrain, including the clutch or torque converter, manual or automatic transmission, driveshaft, axle, wheel ends, and brakes. This course also provides insight into: the structure and function of each component; vehicle integration; and related noise, vibration and harshness issues. You will be equipped to evaluate the space requirements, mounting needs, clearances required, and effect on vehicle response for each component. Fee per person: $1345, $1184 for SAE members.An efficient, robust, and quiet running drivetrain is as essential to customer satisfaction as styling and interior creature comforts.

Benefits of AttendingLearning Objectives
By attending this seminar, you will be able to:
- Discuss both practical and technical aspects of smoothing clutch operation by incorporating cushion and torsional dampers.
- Compare different types of transmission synchronizers, automatic transmission torque converters, hydraulic clutch operation and epicyclic gear trains.
- Describe the interaction of gear ratios and vehicle performance as related to engine horsepower and torque curves.
- Explain phasing and mounting of propeller shafts as related to torsional excitation and secondary couple loads
- Review different types of differentials.
- Compare common misconceptions of limited slip devices to their actual performance.
- Recognize four-wheel drive systems and the need for an inter-axle differential.
- Appraise electronic control of torque through braking and clutching devices.
- Evaluate the total drivetrain package as a system.

Sponsor Background:
About SAEWhat do cars, aircraft, trucks, off-highway equipment, engines, materials, manufacturing, and fuels have in common? SAE. The Society of Automotive Engineers is your one-stop resource for technical information and expertise used in designing, building, maintaining, and operating self-propelled vehicles for use on land or sea, in air or space.
Who we are & what we do
Nearly 80,000 engineers, business executives, educators, and students from more than 97 countries form our network of members who share information and exchange ideas for advancing the engineering of mobility systems. More than 16,000 volunteer leaders serve on our Board of Directors and our many other boards, councils and committees. Our technical committees write more new aerospace and automotive engineering standards than any other standards-writing organization in the world. We publish thousands of technical papers and books each year, and leading-edge periodicals and Internet and CD-ROM products too. Our Cooperative Research Program helps facilitate projects that benefit the mobility industry as a whole. Numerous meetings and expositions provide worldwide opportunities to network and share information. We also offer a full complement of professional development activities such as seminars, workshops, and continuing education programs. The meetings and activities of local sections provide an opportunity to network with colleagues near you.
Services for the public and the profession
Every day, we demonstrate our commitment to society through local, national, and international public awareness programs that promote vehicle safety and maintenance and energy resource conservation. Through the SAE Foundation, we are also deeply involved in the engineering-related education of children, teachers , college students, and faculty. Industry and faculty awards provide recognition to outstanding contributors in the profession.
Since its founding in 1905, SAE's dedicated people, strong technical base, and vision have helped serve the professional needs of engineers and the transportation needs of humanity. We are clearly poised to continue that role into the 21st century.
