Patent ID: 7036360

Claim:
A test rig for dynamic or static testing of a vehicle powertrain apparatus during operation in varying attitudes, said rig comprising: a pair of longitudinally spaced bearing supports adapted to be mounted in fixed relation to a base; an outer frame having spaced longitudinal ends connected by spaced transverse sides, the ends being carried by bearings fixed to said supports and aligned for pivoting motion of the outer frame about a longitudinal axis; an inner frame having spaced longitudinal ends connected by spaced transverse sides, the sides being carried by bearings fixed to the sides of the outer frame and aligned for pivoting motion of the inner frame within the outer frame about a transverse axis; a mounting cradle carried by the inner frame and adapted for mounting a powertrain apparatus for operation in the frame; a first rotatable drive operable to pivot the outer frame about the longitudinal axis relative to the bearing supports; and a second rotatable drive operable to pivot the inner frame about the transverse axis relative to the outer frame; whereby controlled operation of the drives allows tilting of the cradle in any direction relative to a vertical axis for testing the effects of static or dynamic tilting of the powertrain apparatus during operation of the apparatus while mounted in the cradle.
