J643_198906: HYDRODYNAMIC DRIVE TEST CODE

Features

Issuing Committee: Automatic Transmission and Transaxle Committee

Scope

Content

The range of test conditions on the dynamometer shall be sufficient to determine the primary operating characteristics corresponding to the full range of vehicle operations.

The characteristics to be determined are:

a
Torque ratio versus speed ratio and output speed.
b
Input speed versus speed ratio and output speed.
c
Efficiency versus speed ratio and output speed.
d
Capacity factor versus speed ratio and output speed.
e
Input torque versus input speed.

NOTE: For more information about these characteristics and the design of hydrodynamic drives, see "Design Practices--Passenger Car Automatic Transmissions," SAE Advances in Engineering, Vol. 5.
