Abstract:
1. A transmission testing device for testing a test product at a temperature inside of an environmental chamber, wherein the test product is set in the environmental chamber and connected to an input shaft dynamometer through a torque meter arranged out of the environmental chamber, wherein: the test product is arranged to face a hole formed in a face plate, and is fixed to the face plate, and is attached to a test product attachment holder through the face plate, wherein the test product attachment holder is disposed outside of the environmental chamber; the test product attachment holder includes an opened side surface, and a second side surface opposite to the opened side surface, wherein the second side surface is formed with a hole having a box-shape; attachment of the test product to the test product attachment holder is implemented by fixing the face plate under a condition where the hole of the face plate and the hole of the test product attachment holder face each other, and arranging a flange in a hollow formed in the test product attachment holder for connection between the test product and the input shaft dynamometer, and connecting a first end of the flange to an adapter flange of the test product, and connecting a second end of the flange to a rotating shaft of the input shaft dynamometer through the torque meter; and a thermal insulation wall is provided at a test-product-fixing-side inner wall of the test product attachment holder, for suppressing thermal conduction from the environmental chamber.
