Abstract

The invention relates to the field of motor-vehicle technology. The aim of the invention is to achieve a wide tilting angle of the driver's cab of commercial vehicles by using long, resilient torsion bars. The object of the invention consists in being able to use long torsion bars even with restricted installation space and in the process to make an additional bearing bracket for the torsion-bar ends unnecessary. The essence of the invention consists in that the torsion-bar ends are arranged very close to the swivel axis (3) of the driver's cab (1). The torsion bars (7) are passed through the inner web (9) of the frame-side bearing block (4) and are inserted positively and non-positively in the outer web (10) of the frame-side bearing block (4). The torsion-bar ends are arranged on the outer web (10) of the frame-side bearing block (4) such that they are freely supported in the longitudinal direction. The invention can be used in devices for tilting driver's cabs on commercial vehicles. <IMAGE>

title

Arrangement of torsion bars on tiltable driver's cabs of motor vehicles Field of application of the invention The field of application of the invention is automotive engineering. The object of the application is the use of torsion bars to rib cabs on commercial vehicles.

Characteristics of the known technical solutions Bearings are known of torsion bars on tilting cabs that use curved torsion bars and the bent parts of the torsion bars for attachment to the cab and serve on the frame.

These solutions have the disadvantage that the resilient torsion bar length on the dimensions between the cab side member and the frame side member of the opposite one Page is limited and the possible tilt angle of the cab is limited is. At the same time, a relatively large amount of spring material is required.

There are also rotating bar deposits known in which to achieve If the torsion bars are long, the torsion bars are preferably mounted on the frame side via an additional bearing bracket are connected, which requires an increased effort and larger installation space. the mentioned solutions are described in DE-AS 1285900 and DE-OS 2261758.

Aim of the Invention The aim of the invention is to achieve a broad Tilt angle of the cab it of commercial vehicles through the use of large resilient Dresta lengths and that Berzegungs restrictions of the torsion bars are avoided.

The essence of the invention The technical problem The technical problem the invention consists in the fact that large torsion bar lengths even with limited installation space can be used and no additional bearing bracket for the torsion bar ends are necessary.

The features of the invention In an arrangement of preferably two Crossing torsion bars for tilting cabs are the torsion bar ends the cab side and on the frame side very close to the axis of rotation of the cab arranged and between the driver's cab-side bearing element and frame-side bearing block attached.

The features of the invention are that the torsion bars through the inner web of the frame-side bearing block passed through and the torsion bar ends in an I-aging in the outer web of the frame-side bearing bracket and are pushed in with a force fit.

The torsion bar ends are on the outer web of the frame-side bearing block arranged freely stored in the longitudinal direction, so that a restriction of movement Torsion bars is avoided.

By using the full length of the torsion bars, a further Allows tilt angle of the cab.

Since no additional assembly elements are required, a A compact design requiring little installation space is achieved.

Busfuhrunffsbeispiel The drawing belonging to the embodiment shows the arrangement of the torsion bars between the cab and frame in the storage elements.

The bearing element 2 is mounted on the driver's cab 1 below the side members, through the area of which the axis of rotation 3 of the driver's cab 1 goes.

The bearing block 4, which is connected to the bearing element 2 via the axis of rotation 3 is, establishes the connection to the frame 6 via the console 5.

In order to largely avoid bending, the torsion bars 7 are on the driver's cab side fastened in the axis of rotation 3 in a receiving block 8 of the bearing element 2.

In order to have an extremely long torsion bar, depending on the installation conditions to be able to use, the torsion bars 7 are guided through the inner web 9 and in the outer web 10 attached.

The torsion bar ends here, designed as a segment of a circle, in correspondingly form-fitting, but to achieve a sufficient gap enlarged sections of the receiving block 8 and of the outer web 10.

The torsion bars 7 are useful with the already assembled Share, bearing element 2 with the bearing block 4, by simply plugging the Torsion bars 7 preassembled in the receiving block 8 and in the outer web 10 and then screwed to the cab 1.

Between the immediate torsion bar storage parts, such as the receiving block 8 and outer web 10 and the torsion bars 7 is not connected in the longitudinal direction and thus no restriction of movement of the torsion bars.

In this compact design, the torsion bars 7 are not used connected directly to the bearing parts by additional assembly elements.
