<p>This method and this device use detecting members incorporated into the hub of the corresponding wheel and connected to an electrical circuit comprising an apparatus which indicates the value of the torque transmitted by this wheel. The detecting members that are used are electrical strain gauges (15a, 15b, 15c, 15d) arranged on one of the ends of the axle (9) of the wheel. These gauges are placed in such a way that they can be influenced only by variations in the force acting on this end in the horizontal plane passing through the centre of the wheel axle. In this way the measurement is only of the horizontal component of the shearing force on the wheel axle, from which the value of the torque transmitted to it can be deduced. Instead of being attached directly to one of the ends of the wheel axle, the strain gauges can be attached to a part connected to this end and flexible or deformable in the horizontal plane passing through the centre of the wheel axle. …<IMAGE>… </p> |
