Clutch Requirements for High-Torque Truck and Bus Engines

1997-10-01
HISTORICAL
J2408_199710
Although not limited to, these clutch requirements are normally used on trucks considered as heavy duty (Class 8). This SAE Information Report defines and discusses clutch and related component configurations which will become the subject of future SAE Recommended Practices to promote standardization of clutch installations and mounting dimensions for use with pull- type heavy-duty clutches.

Commercial Truck and Bus SAE Recommended Procedure for Vehicle Performance Prediction and Charting

2012-07-31
HISTORICAL
J2188_201207
This SAE Recommended Practice takes into account modern standardized methods for collecting and summarizing data that has an effect on vehicle steady-state performance, such as engine output (gross and net), transmission losses, drivetrain efficiency, vehicle aerodynamic devices for various vehicle and body configurations, as well as road surface variations and air density variations resulting from altitude and barometric effects. The procedure does not address vehicle transient performance (acceleration, braking, and cornering), because of the considerable amount of additional data required such as moment of inertia of all the rotating parts. Nor does it address vehicles with torque converters and automatic transmissions. This document is, therefore, intended for vehicles having fixed-ratio type transmissions and positive engagement clutches. Metric and ISO unit conversions are provided in the metric conversion tables at the end of this procedure (see Appendix B).
