FIELD: transportation.
SUBSTANCE: invention can be used at automotive, wheeled tractors, road building machines production plants, and in service and repair sphere of mentioned facilities. Power test stand for wheeled vehicle contains base, carrier chassis dynamometer hard-mounted on crankshaft installed on base, and loading device. The latter is mounted on crankshaft throw on bearing assembly in the form of brake drum hard-mounted relative to base and made in the form of pneumatic-tired roller. Geometrical axis of brake drum is shifted relative to rotation axis of carrier chassis dynamometer by the value of crankshaft eccentricity. Brake drum is performed with possibility of internal pressure adjusting. During testing wheeled vehicle is loaded by moment of antitorque to driving wheels up to their slipping.
EFFECT: providing of possibility to reduce antitorque moment during operation.
