Abstract: A device for dynamically exciting a component, in particular a chassis component of a motor vehicle has an actuator (10) with a piston rod (20) and an actuator housing (30). A connecting element (40) is coupled to the piston rod (20) of the actuator (10). A coupling (50) is coupled to the connecting element (40) for connection to the component. The connecting element (40) is coupled to the piston rod (20) in such a manner that the coupling is substantially moment-free.

Abstract: A test bench for motor vehicles and/or axles of motor vehicles for simulating gyroscopic torques of a rotating wheel includes a wheel replacement system connected to an axle of the motor vehicle. The wheel replacement system includes a wheel replacement mass and a driver for driving the wheel replacement mass. The test bench also includes an arrangement for applying testing forces, testing torques and testing movements in a longitudinal, lateral and/or vertical direction to the motor vehicle and/or axles of the motor vehicle. The driver is configured to set the wheel replacement mass in rotation. The arrangement for applying testing forces, testing torques and testing movements is configured to generate a gyroscopic torque of the wheel replacement mass which is set in rotation, by applying testing forces, testing torques and testing movements in the longitudinal, lateral and/or vertical direction to the motor vehicle and/or the axles of the motor vehicle.

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.
