Abstract

The invention relates to the field of automotive engineering. The aim of the invention is to achieve a further tilt angle of the cab of commercial vehicles through the use of large resilient Drehstablaengen. The object of the invention is that even with limited space large screen sizes can be used and no additional bearing bracket for the torsion bars are necessary. The essence of the invention is that the torsion bar ends are arranged very close to the axis of rotation 3 of the cab 1. The Drehstaebe 7 are guided through the inner web 9 of the frame-side bearing block 4 and inserted in the outer web 10 of the frame-side bearing block 4 formschlüssessig and kraftschluessig. The torsion bar ends are arranged on the outer web 10 of the frame-side bearing block 4 in Laengsrichtung freely stored. Field of application of the invention are devices for tilting driver's cabs on commercial vehicles.

Arrangement of torsion bars on tiltable cabs of motor vehicles

Field of application of the invention is the automotive technology. Object of the application is the use of torsion bars for tilting cabs on commercial vehicles.

α he be kjinn t ££ ^ Sife ¹¹ ^ · ^ £ ϊ * ®5ίίο s ung ^e S are known mountings of torsion bars at tiltable cabs, in which curved torsion bars are used and the bent-in parts of the torsion bars for attachment to the cab and to the frame serve. These solutions have the disadvantage that the resilient torsion bar length is limited to the dimensions between the cab side rail and frame side members of the opposite side and the possible tilt angle of the cab is limited thereby. At the same time, a relatively large amount of spring material is required. Turntable deposits are still known in which the torsion bars are preferably connected on the frame side via additional bearing brackets in order to achieve large torsion bar lengths, which requires increased expenditure and larger installation space. The solutions mentioned are described in DE-AS 1285900 and DE-OS 2261758.

The aim of the invention is the achievement of a wide tilt angle of the cab of commercial vehicles by using large resilient Drehstablängen and that movement 'tion restrictions of the torsion bars are avoided »Das_Wesen <3er__Erfindung The__technische__Uuf

The technical object of the invention is that even with limited space large Drehstablängen can be used and no additional bearing bracket für.die rotary rod ends are necessary.

In an arrangement of preferably two intersecting torsion bars for tilting cabs, the torsion bars are arranged on the cab side and on the frame side very close to the axis of rotation of the cab and fixed between the cab side bearing element and frame-side bracket. The features of the invention are that the torsion bars are guided through the inner web of the frame-side bearing block and the torsion bar ends are inserted positively and non-positively in a holder in the outer web of the frame-side Lagerbokkes,

The torsion bar ends are arranged on the outer web of the frame-side bearing block in the longitudinal direction freely stored, so that a restriction of movement of the torsion bars is avoided, By exploiting the full length of the torsion bars a wide tilt angle of the cab is possible. Since no additional mounting elements are required, a compact design that requires little installation space is achieved.

Ausführungsbeisßiel

The drawing belonging to the exemplary embodiment shows the arrangement of the torsion bars between the driver's cab and the frame in the mounting elements. Below the longitudinal members, the bearing element 2 is mounted on the driver's cab 1, through the region of which the axis of rotation 3 of the driver's cab 1 passes.

The L _a gerbock 4-, which is connected via the axis of rotation 3 to the bearing element 2, establishes the connection with the frame 6 via the Konscl 5.

To substantially prevent deflection, the torsion bars 7 £ ahrerhausseitig in the rotation axis 3 in a receiving block 8 of the bearing element 2 is attached. In order to use an extremely long torsion bar according to the installation conditions, the torsion bars are guided by the inner web 9 and fixed in the outer web 10.

The torsion bar ends in this case, formed as a circular section, in accordance form-fitting, but to achieve a sufficient clearance enlarged sections of the receiving block 8 and the outer web 10 ·

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

Between the immediate Drehstablagerungsteilen, such as receiving block 8 and outer web 10 and the torsion bars 7 is no connection in the longitudinal direction and thus no movement restriction of the torsion bars. In this compact design, the torsion bars 7 are directly connected to the storage parts without the use of additional mounting elements.
