Wheel, test bench and method for determining the aerodynamic characteristics of a test vehicle

摘要

the invention relates to a wheel (2) for a test vehicle (4) and the wheel (2), a wheel (70) and a hub (60) in which the flux of force between the hub and the wheel rim (60) and (70) and at least one load sensor is arranged.the invention also concerns a test with a test vehicle, which has several road wheels, with one or more of the road wheels as the wheel (2) with a between the hub (60) and the rim (70) arranged load sensor (10) is trained. the invention also relates to a corresponding method for determining aerodynamic characteristics of a testfahrzeugs (4).in particular, one with a wide band (9) equipped test can measure widerstandsbeiwerten relevant forces, with the help of the erfindungsgemu00e4u00dfen wheel (2) with a load sensor (10) to be reliably measured. on the use of the flow in unsolicited manner influencing u00fcberkopfwaagen can be dispensed with.
