Patent ID: 11506551

Abstract:
A dynamometer test unit configured for use in a vehicle dynamometer system for dynamometer testing of a vehicle, the dynamometer test unit being configured to be connected to a wheel shaft of a vehicle, the dynamometer test unit comprising a power source having a stator and a rotor and being configured to, during testing, apply torque to a wheel shaft of the vehicle being tested, the power source being carried by a stator support, the stator being journaled in relation to the stator support, the dynamometer test unit further comprising means for measuring torque comprising an elastic strip, wherein the elastic strip connects the stator to the stator support, thereby restraining relative rotational movement between stator and stator support, and configured to transfer force between the stator and stator support, the elastic strip being firmly secured in a manner such that it is subjected to homogenous tensile prestress in a longitudinal direction of the elastic strip.
