Abstract: A ending bar is designed as a bumper and composed of a front and a rear shell, the rear shell of which is under tensile prestress by means of an appropriate connection to the front shell.

Abstract: An independent wheel suspension for a vehicle wheel comprises a wheel carrier having a steering linkage lever formed on an upper part thereof, a lower control arm connected to the carrier, an upper control arm connected to the carrier and pivoted in a bearing, and a steering tie rod connected to the steering linkage lever and to a steering mechanism. The steering linkage lever extends outwardly over the apex of the wheel to a point of connection with the steering tie rod. The tie rod lies in a horizontal plane and is substantially parallel to a longitudinal vertical center plane of the vehicle. The upper control arm extends longitudinally in side-by-side relation to the steering tie rod, and is pivoted about an axis which extends obliquely from a point of intersection with a central transverse wheel plane outwardly and downwardly (moving from the plane toward the bearing member). Provision is made for interconnecting two or more wheels provided with essentially identical suspensions in a serial fashion.

Abstract: A device is provided to prevent lateral movements of a motor vehicle body relative to a vehicle axle, having a fixture pin, a rocker arm constructed as a double lever and pivotable by its central part about the fixture pin, and two guide rods which are each connected articulately by their one end to one of the rocker arm arms. In order to keep the overall height for the rocker arm mounting as low as possible and to be able to achieve high load capacity both in the rocker arm axis direction and also perpendicularly to the latter, together with high tilting rigidity, the rocker arm is mounted in a circumferential groove of a bearing body which consists of two discs pluggable onto the fixture pin, mutually connectable integrally in rotation and conjointly forming the circumferential groove by their circumferential surfaces, and which is anchorable on the fixture base supporting the fixture pin.

Abstract: A pneumatic spring for motor vehicles which includes a closed spring volume and two spring surfaces of different sizes adapted to be subjected to pressure acting in opposite directions. The two spring surfaces each have an effective spring surface which is variable in size as a function of travel of the pneumatic spring. A separate support arrangement is provided for each of the spring surfaces for supporting the spring surfaces so as to be coaxial with respect to one another. A linking construction is provided for elastically linking the two support arrangements with one another so as to enable an axial distance between the support arrangements to be variable within predetermined limits as a function of a pressure of the closed spring volume.

Abstract: A pneumatic spring for motor vehicles which includes two supports as well as closed spring volumes and two spring surfaces of different sizes which surfaces are subjected to pressure in opposite directions and which are variable as a function of road clearance. The surfaces are supported coaxially against one another with the spring volume being formed by two roll bellows defining a common chamber. Effective spring surfaces of the bellows facing away from each other are supported upon spring pistons of different diameters which are connected together. The spring pistons and a casing associated with the roll bellows form the two supports.

Abstract: A vehicle, especially a cab-over engine commercial vehicle, with a steering wheel which is disposed generally horizontally in a normal operating position and a steering column which is generally vertical and displaceably supported in the direction of the vehicle from in the vicinity of the steering wheel. A steering assembly formed by the steering wheel and steering column is displaceable to a protective position in which position the steering wheel assumes a fixed position when the steering column is displaced in the direction of the front of the vehicle. The steering column and steering wheel are automatically and positively displaced into their protective positions as a function of the deceleration of the vehicle and/or deformation of the vehicle front.

Abstract: A pneumatic spring for vehicles which spring includes two supports as well as at least one closed spring volume and two differently sized spring areas which are subjected to a pressure acting in opposite directions. The two spring surfaces are separated from one another and are variable in size as a function of the travel of the pneumatic spring, two roll bellows are arranged in a casing of the pneumatic spring with opposite spring surfaces of the bellows being supported upon connected spring pistons. The supports are formed, on the one hand, by the spring pistons and, on the other hand, by a casing associated with the walls of the roll bellows. Partial volumes are defined by the roll bellows with the partial volumes being separated from one another so as to maintain the respective volumes essentially independent of the travel of the pneumatic spring.

Abstract: A truck with a driver cab that includes two separate structural units, of which one is equipped as independently spring-supported operating cell essentially only with seating elements or seating and berthing elements as well as with control and operating elements while the other unit forms as covering and/or support unit a mounting unit for the operating cell and shields the operating cell on the rear side or on the rear and bottom side thereof.
