Wheel test stand and method for determination of the aerodynamic characteristic values of a test vehicle

摘要

The present invention relates to a wheel (2) for a test vehicle (4), wherein the wheel (2) a rim (70) and a hub (60), and wherein in the flow of force between the hub (60) and the rim (70) is arranged at least one force sensor. The present invention also relates to a test stand having a test vehicle which has a plurality of vehicle wheels, wherein one or more of these vehicle wheels in the form of a wheel (2) with a between the hub (60) and the rim (70) force sensor (10) are formed. The present invention also relates to a corresponding method for the determination of aerodynamic characteristic values of a test vehicle (4). In particular in the case of a with a broad band (9) the test stand, which is equipped for the measurement of the relevant forces accordance with the aid of the wheel according to the invention (2) with force sensor (10) be reliably measured. The use of the flow in an undesirable manner by way of influencing the head of the scales can be dispensed with.
