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

摘要

The wheel (2) has a force sensor (10) arranged at a power flow between a hub (60) and a wheel rim (70) for detecting a force along a vertical direction (z). The force sensor comprises a bearing device, sensor elements, a housing and comprises resistive wire strains for detecting the force acting on the bearing device. The housing of the force sensor is flange-mounted on the hub, and the sensor is coupled with the wheel rim by the bearing device. An independent claim is also included for a method for determining aerodynamic characteristic values of a test vehicle.
