Abstract
A wheel-force dynamometer (1) for measuring, via force sensors (6), force and torque that act upon a vehicle tire (2a) and a vehicle wheel (2). The vehicle wheel (2) is mounted to rotate by way of a wheel axle. The wheel-force dynamometer (1) is characterized in that the wheel axle is in the form of a rotor (3) which is hydrostatically mounted, axially fixed and able to rotate in the circumferential direction, in a rigid and positionally fixed housing (5).
Claims15
A wheel-force dynamometer for measurement of force and torque, via force sensors, that act upon a vehicle tire and a vehicle wheel,
- the vehicle wheel being mounted to rotate about a rotational axis by way of a wheel axle,
- the wheel axle being designed as a rotor, the rotor is connected to the vehicle wheel in a rotationally fixed manner, the rotor is mounted axially fixed and circumferentially rotatable in a rigid and positionally fixed housing, the housing has a housing body and a housing lid that are fixed to each other such that the rotor is axially fixed therebetween relative to the housing.
A wheel-force dynamometer comprising force sensors for measuring force and torque that act upon a vehicle tire and a vehicle wheel,
- the vehicle wheel being fixed to a rotor such that the vehicle wheel and the rotor rotate in unison around a rotational axis,
- the rotor being mounted in a housing that is rigid and fixed in position, the housing has a housing body and a housing lid that are fixed to each other such that the rotor is axially fixed and rotatable therebetween with respect to the housing.
