Abstract:
A wheel is provided for a test vehicle. The wheel has a rim and a hub, and whereby at least one force sensor is placed in the flux of force between the hub and the rim. A test stand is provided with the test vehicle that has multiple vehicle wheels and one or more of these vehicle wheels is embodied as a wheel with a force sensor placed between the hub and the rim. An appropriate procedure is provided for determining the aerodynamic characteristics of the test vehicle. Especially with a test stand equipped with a wide belt, the forces relevant to measurement of the drag coefficients can be reliably measured with the aid of the specific wheel with the force sensor. Use of overhead scales that have an undesired effect on the flow can be dispensed with.
