MANUAL TRANSMISSION AND TRANSAXLE EFFICIENCY AND PARASITIC LOSS MEASUREMENT

1992-04-01

HISTORICAL

J1540_199204

Because of the intense focus on CAFE and fuel emission standards, optimization of the automobile drivetrain is imperative. In light of this, component efficiencies have become an important factor in the drivetrain decision-making process. It has therefore become necessary to develop a universal standard to judge transmission efficiency. This SAE Recommended Practice specifies the dynamometer test procedure which maps a manual transmission’s efficiency. The document is separated into two parts. The first compares input and output torque throughout a specified input speed range in order to determine “in-gear” transmission efficiency. The second procedure measures parasitic losses experienced while in neutral at nominal idling speeds. The application of this document is intended for passenger car and light truck. All references to transmissions throughout this document include transaxles.

Manual Transmission Efficiency and Parasitic Loss Measurement

J1540_200011

Because of the intense focus on fuel economy and fuel emission standards, it has become imperative to optimize vehicle drivetrains. In light of this, component efficiencies have become an important factor in the drivetrain decision-making process. It has therefore become necessary to develop a universal standard to judge transmission efficiency. This SAE Recommended Practice specifies a test procedure which maps torque transmittal efficiency and parasitic losses for manual transmissions. The application of this document is intended for manual transmissions used in light (class 4) through heavy truck applications with both simple and compound ratio structures. This document is separated into two parts. The first compares input and output torque throughout a specified input speed range in order to determine the overall transmission efficiency. This test is used to evaluate all forward gears; testing in reverse is optional.
