Abstract: A sliding door guide for motor vehicles, in particular vans and utility vehicles, includes an upper, lower and a central guide mechanism to hold the door in place. The door is flush with the side panel of the vehicle when closed and extends beyond the side of the side panel when open and can essentially be moved parallel to the side panel. The central guide mechanism includes a carriage and sliding rails. The sliding rails are arranged on the inside of the door, in which the carriage is hinge-mounted on a reversing lever and in turn the reversing lever is hinge-mounted on a pillar of the vehicle body. A first anchor is mounted in front of the carriage when seen in the direction of opening, and a second anchor is mounted in the side panel approximately half way along the path of opening.

Abstract: The invention describes a sliding door guide for motor vehicles, in particular vans and utility vehicles, with a carriage (7) and sliding rails (6), in which an upper, lower and a central guide mechanism hold the door (1) in place and in which the door (1) is flush with the side panel (2) of the vehicle when closed and extends beyond the side of the side panel (2) when open and can essentially be moved parallel to the side panel. The sliding rails (6) on the inside of the door are characteristic of the invention as the central guide mechanism, in which the carriage is hinge-mounted on a reversing lever and in turn the reversing lever is hinge-mounted on a pillar (4) of the vehicle body, the first anchor (6, 13) is mounted in front of the carriage (7) when seen in the direction of opening, and a second anchor (11) is mounted in the side panel (2) approximately half way along the path of opening.

Abstract: The measuring cell comprises two systems of transducers (strain gauges) disposed respectively in two regions of concentration of force of the cell, each system comprising a pair of transducers arranged axially within a plane, the angle enclosed between the plane of the first pair and the plane of the second pair being of 60.degree.. This permits the suppression of the third harmonic in the output signal delivered by a bridge in which the transducers are connected. The opposite arms of the bridge comprise, respectively, a transducer of the first and a transducer of the second pair, the transducers of the first pair and the transducers of the second pair being arranged in the cell symetrically with respect to the axis of the cell.

Abstract: The measuring device of the useful load and of the load on the axles of a truck comprises load cells mounted on a truck frame. A plate transmits the weight of the tipper and the one of the useful load to the load cells. The device comprises three load cells forming a system having three bearing points. The axis of the single front load cell is perpendicular to the common axis of the rear pair of load cells. This arrangement and the fact that each load cell is mounted on a knee-joint permits to eliminate the parasitic constraints of flexion and torsion on the load cells so that the load cells are submitted only to the constraints resulting from the weight of the tipper and the one of the useful load which improves considerably the precision of the measurement.
