A Familiarization of Drivetrain Components

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.

What Will You Learn

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.

Is This Course For You

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.
