Abstract:
1. A powertrain testing apparatus for testing performance of a vehicle powertrain provided with an input shaft oriented on a first axis and an output shaft oriented on a second axis offset from the first axis, the powertrain testing apparatus comprising: an input motor that simulates and replicates rotation of a vehicle-drive engine; an output motor that simulates and replicates load applied to the output shaft of the powertrain; an input side support including an input connection shaft for connection to the input shaft of the powertrain, and an attachment device for attaching a housing of the powertrain; an output side support including an output connection shaft for connection to the output shaft of the powertrain; a vibration generator that simulates and replicates vibration transmitted to the powertrain from a road surface during vehicle travel; a vertical adjustment unit for changing an inter-shaft vertical distance between the input connection shaft and the output connection shaft by relative movement between the input side support and the output side support; and a horizontal adjustment unit for changing an inter-shaft horizontal distance between the input connection shaft and the output connection shaft by relative movement between the input side support and the output side support.
