Sakor Technologies Inc., high-performance dynamometer systems provider, has developed a new test stand for testing clutches, transfer cases, and other torque transfer devices for a major international powertrain components manufacturer. The powertrain test stand is claimed to be powerful, flexible and designed for maintainability, and will be used for testing torque transfer components in small passenger to medium industrial vehicles.
The Sakor test system, one of six built for the customer, features dual 420 kW dynamometers that can operate at up to 6,000 rpm, the company said. It added that the dynamometer system offers maximum continuous torque of 4,010 Nm, with up to 150 % overload for up to 30 seconds. The test stand can be adjusted easily, in order to be able to adapt to any transfer case/torque transfer device geometry, Sakor noted. The system is controlled by Sakor’s DynoLAB data acquisition and control system, which provides fully-automated test procedures for all customer testing protocols.
The dynamometers feature unique adjustable output geometry, which enables users to configure the system to account for different input and output shaft centre lines and drop angles, explained Sakor. It said this makes testing less expensive and safer, while providing better data accuracy, as well as reducing system setup time. A modular cooling system is mounted below the dynamometer and can be easily accessed for maintenance, the company added.
The new test stand features a wide array of data acquisition channels, and can collect information on temperature, pressure, flow, and speed. With controller area network (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.
Randal Beattie, President, Sakor Technologies, said the new test stand has been built for maximum flexibility and adjusts quickly and easily to any transfer case system being tested. 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, he added.
