Abstract
A test stand for vehicles having opposed motive drive outputs including a stand for supporting the vehicle to be tested in a predetermined position with its motive drive outputs free from engagement with surrounding structure, a pair of dynamometers, one on each side of the stand, a pair of releasable couplings, one drivingly associated with each of the dynamometers, and adapted to be engaged with a corresponding one of the motive drive outputs of a vehicle on the supporting stand and a movable mount for at least the releasable couplings so that they may be moved toward and away from each other and the supporting stand. Also disclosed is an improved dynamometer construction, an improved self-aligning coupling and an improved method of testing a mobile mechanical power source such as a vehicle.
