Title:
DUAL-PURPOSE DYNAMOMETER
Document Type and Number:
Japanese Patent JP2016004047
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dual-purpose dynamometer assembly capable of maintain a test chamber at extreme temperatures without high cost.SOLUTION: A dual-purpose dynamometer assembly comprises: a dynamometer motor; a chassis dynamometer roll that can be driven by a vehicle wheel; and a powertrain dynamometer shaft that can be driven by a vehicle powertrain. A gearbox is disposed among the dynamometer motor, the chassis dynamometer roll, and the powertrain dynamometer shaft and rotatably couples the dynamometer motor with the chassis dynamometer roll and the powertrain dynamometer shaft. A chamber wall defining a test chamber is disposed between the dynamometer motor on one side and the chassis dynamometer roll and the powertrain dynamometer shaft on the other side such that the dynamometer motor is disposed outside of the test chamber. There is one aperture penetrating the chamber wall through which the dynamometer motor is connected to the chassis dynamometer roll and the powertrain dynamometer shaft. Accordingly, the dynamometer motor is isolated from extreme temperatures within the test chamber.
