Patent attributes
A mobile test unit for testing a powertrain component such as a transmission is used in a test cell. A test unit includes a movable, generally horizontal base plate, and a frame spaced from the base plate. A headstock is secured to the frame for supporting the transmission. An adjustable support, which is arranged on each of four corners of the frame in the example embodiment, interconnects the frame to the base plate. The adjustable supports are movable in a vertical direction, in one example, between multiple positions to achieve a desired orientation relative to the base plate. In particular, the orientation of the frame is adjusted to obtain a desired rotational and/or tilt angle that corresponds to a rotational and/or tilt angle of the transmission when installed into a vehicle. The transmission can be installed onto the test unit, and the test unit can be moved into and out of a test cell. The example test unit is capable of replicating the orientation of the transmission when installed in a vehicle to provide more representative test data. Furthermore, the adjustments to the test unit can be done outside of a test cell to increase the time during which the test cell can be utilized.
