power & propulsion – powertrain/drivetrain

A Familiarization of Drivetrain Components
I.D.# 98024

April 15 – 16, 2013 (8:30 a.m. – 4:30 p.m.)
www.sae.org/pdevent/98024
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.
Attendees will receive a copy of James Halderman’s book, The Automotive
Technology, 4th Ed.
Learning 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.
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.
