Not available for purchase at this time.
Document Number: J3039
Project Initiation: 03-25-2013
Sponsor Name: Andreas E. Perakes
Title
Definition and Measurement of Power Transfer Unit Speed-Dependent Parasitic Loss
Scope
This SAE Recommended Practice covers power transfer units (PTUs) used in passenger car and light truck applications. PTUs may be of the chain, geared, single- or multi-axis type and may incorporate a disconnect system that is manually or electronically shifted, although other configurations are possible. The operating points (speeds, temperatures, etc.) were chosen to mirror those of the United States Environmental Protection Agency Vehicle Chassis Dynamometer Driving Schedules (DDS).
