  • Torque converter dynamometer and method of using same
    Patent number: 6651493
    Abstract: A dynamometer provides an apparatus and method for testing a torque converter without requiring that an automotive transmission be attached. The dynamometer includes a prime mover mounted on a frame for driving the torque converter. A dynamic loading device with an eddy current brake is movably mounted on the frame. An adapter extends between the loading device and the torque converter and has passages for routing hydraulic fluid to and from the torque converter. Sensors connected to a computer monitor pressures, temperatures and fluid flow.

  • Apparatus and methods for testing transmissions
    Patent number: 6343504
    Abstract: This invention pertains to transmission testers, and specifically to automatic transmission testers, and methods for their use. The headstock is mounted for pivotation about a vertical axis. A novel eddy current brake provides active control of loading of the transmission while the transmission is being tested. The prime mover is preferably an electric motor, with motor controls, adapted to temporarily suspend acceleration of the speed when the transmission shifts gears.
