Sakor Technologies recently provided a new test stand for analyzing clutches, transfer cases, and other torque transfer devices for a major international provider of powertrain components. It will predominantly be used for testing torque transfer components in small passenger to medium industrial vehicles.
The Sakor system – one of six built for the customer – features dual 420kW dynamometers that can operate at up to 6,000rpm. The dyno offers maximum continuous torque of 4,010Nm, with up to 150% overload for up to 30 seconds.
It is controlled by Sakor’s DynoLab data acquisition and control system, which enables fully automated testing. Featuring a wide array of data acquisition channels, the new test stand can collect information on temperature, pressure, flow and speed. With CAN ports for communication with the customer’s smart controllers, the system can automatically shift the unit under test and also has the ability to directly control older devices that lack CAN communication capability.
The dynamometers feature unique adjustable output geometry, enabling users to configure the system to account for different input and output shaft center lines and drop angles. This makes testing less expensive and safer and provides better data accuracy. It also reduces system set up time.
A modular cooling system is mounted below the dynamometer and can be easily accessed for maintenance.
“The new test stand has been built for maximum flexibility and adjusts quickly and easily to any transfer case system being tested,” said Randal Beattie, president of Sakor. “It takes minimal operator time to set up and install test units, so what used to take many hours and long drive shafts can now be done in a matter of minutes.”
