Powertrain testing apparatus
First Claim
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.

Abstract
A powertrain testing apparatus for testing performance testing of a powertrain provided with an input shaft and an output shaft that are disposed on different axes. The testing apparatus includes an input motor that replicates rotation of a vehicle-drive engine, an output motor that replicates the load applied to the output shaft in actual service, an input side support having an input connection shaft for connection to the input shaft, an output side support having an output connection shaft for connection to the output shaft, and a vibration generator that replicates vibration transmitted from a road surface in actual service. Vertical and horizontal adjustment units enable inter-shaft distances D1 and D2 between the input connection shaft and the output connection shaft to be changed. Constant velocity joints respectively connect the input motor and the input connection shaft and the output motor and the output connection shaft, thus enabling eccentric positioning thereof.
