Messrad

The invention relates to a measuring wheel having a hub and a rim and at least one connection arrangement between the hub and the rim, and having one or several measuring elements in or on the connection arrangement for measuring the forces and/or torques which act on the rotating measuring wheel. The connection arrangement between the hub and the rim comprises (a) an axial connection arrangement connecting the hub to the rim rigidly in the radial directions and about the vertical and horizontal axes of the measuring wheel but flexibly in the other directions, (b) a radial connection arrangement connecting the hub to the rim rigidly in the radial directions of the measuring wheel but flexibly in the other directions; (c) a tangential connecting arrangement connecting the hub to the rim rigidly in the circumferential directions about the rotary axis of the wheel but flexibly in the other directions. At least one measuring element is provided in or on at least one of the connection arran gements to measure its force or its torque which is transferred in the direction between the hub and the rim in which the latter is rigidly connected to each other by the associated connection arrangement.
