Abstract
Apparatus and methods for testing a front wheel drive automotive transmission having a drive input adapted for connection to the engine driveshaft and two driven outputs adapted for coupling to the axles of the front wheels. The testing apparatus comprises a drive input shaft corresponding to the engine driveshaft and a pair of output shafts corresponding to the vehicle axles. Each output shaft is coupled to a single driven shaft by a positive drive, non-slip coupling mechanism so that neither of the output shafts can rotate at a speed different from that of the other. The single, driven shaft is provided with a flywheel which simulates inertial forces. The input driveshaft is coupled to a variable speed motor and the single, driven shaft is coupled to a similar motor which is operable at selected speeds to impose varying load conditions on the transmission. The positive drive couplings preferably rotate the single, driven shaft at a speed greater than that of the driving output shafts so as to minimize the mass of the flywheel.
