    摘要: A wheel load indicator comprises a rectangular flat plate (1) of a light material having measuring properties. A series of recesses (4) forming webs (5) are provided along two lateral edges (6) of the plate (1). Strain gauges (12) are adhesively bonded to walls of bores (10) in the area of the webs (5) to determine the shearing stress under the load of a wheel (100) which has driven on the bending portion (3).

    摘要: An arrangement for measuring the distance between the axles or wheels of a vehicle. A roadway with at least one sensing sill. A sensing section along the roadway with one end a maximum length from the sill corresponding to the smallest spacing between axles to be measured and another end a minimum length from the sill corresponding to the largest spacing between axles to be measured. A first wheel on a first axle of the vehicle being located at the sensing sill and a second wheel on a second axle on the vehicle being located on the sensing section when measuring the distance between the two axles by using the distance measured between the second wheel and the sensing sill.

    摘要: A wheel-load sensor cast into a mass of material for positioning in a depression in a pavement or the like. The sensor includes a piezo-electric pickup. The pickup encloses an inner electrode and is enclosed in at least one outer electrode. The inner electrode is a solid conductor and the outer electrode a hollow conductor. The pickup can be positioned in the pavement. Some sections (16) of the wall of the piezo-electric pickup (11) more or less parallel the surface of the road. These sections are accommodated subject to a prescribed pressure between the adjacent sections of the wall of the hollow conductor (13') that constitutes the outer electrode and the other sections (16') of the wall of the piezo-electric pickup in the hollow conductor and away from the rest of the walls.
