ABSTRACT:
A drive-dynamometer system particularly adapted for automated testing of parts such as vehicle engines. The dynamometer is a hydrostatic system having a fixed displacement motor connected to, and a variable displacement pump spaced from the part being tested, the pump having motor means for driving it. The system has a closed hydraulic loop connecting the motor and the pump whereby the engine may be selectively cold-tested or hot-tested, the motor during hot-testing acting as a pump and the pump acting as a motor which therefore drives its motor means. Preferably, this comprises a synchronous electric motor, which, when acting as a generator, creates useful electric power for the plant in which the unit is installed. Means are provided for adjusting the displacement of the pump, and a control loop system is provided for the pump adjusting means to simulate different load or inertia conditions. The fixed displacement motor has two motive connections, and a device is preferably provided for sensing the pressure differential between said connections to indicate positive or negative torque.
