B. rubber cords, in the axle tube ( 8th ) be supported. Upon rotation of the axle shaft ( 9 ) are inserted between the outer tube wall and a recess of the axle shaft profile spring elements ( 28 ) subjected to compression or shear and unfold a spring action.

The side views of 2 and 3 show this arrangement and formation of a rubber spring axis ( 7 ). In the axle configuration shown, two axle shafts ( 9 ) at the end in the axle tube ( 8th ) and are stored separately from each other and independently movable, whereby the vehicle wheels ( 18 ) are suspended individually and are movable.

At the front side of the axle tube ( 8th ) passing axle shaft ( 9 ) is at the end a Radschwinghebel ( 11 ) with its axle-side lever end ( 13 ) rotationally fixed. At the other end of the wheel ( 12 ) carries the Radschwinghebel ( 11 ) a stub axle ( 14 ) and the hub rotatably mounted thereon ( 17 ) with the vehicle wheel ( 18 ).

The shock absorber arrangement ( 19 ) has a shock absorber ( 20 ) located between the chassis ( 2 ) and the wheel-side lever end ( 12 ) of the wheel swing lever ( 11 ) is arranged. The shock absorber ( 20 ) is in this case with its ends and bearing eyes ( 23 ) on the wheel swing lever ( 11 ) or at the end of the lever ( 12 ) and on the chassis ( 2 ) stored. The storage can be articulated. For this purpose, two swivel bearings ( 21 . 22 ) intended.

The wheel swing lever ( 11 ) at the wheel-end of the lever ( 12 ) a recording ( 15 ) for the one end of the shock absorber ( 20 ) and for the formation of the camp ( 21 ) on. The recording ( 15 ) can in any way and at any suitable point of the lever end ( 12 ) can be arranged. In particular, it can be located directly on the body of the Radschwinghebels ( 11 ) are located.

In the embodiment shown, the receptacle on the stub axle ( 14 ) or in its area. The wheel ( 18 ) is thereby by the shortest route with the shock absorber ( 20 ) connected. The on the chassis ( 2 ) outward-pointing stub axle ( 14 ) is at the end of the lever ( 12 ) attached in a suitable manner, for. B. by a screw in a lever opening, by a welded joint or the like. This compound can be solvable or solid. In the embodiment shown, the receptacle ( 15 ) at the rear of the stub axle ( 14 ) and Z. B. arranged in alignment with the longitudinal axis thereof and points to the longitudinal member ( 3 ).

The recording ( 15 ) can be used as a journal ( 25 ), which in the aforementioned manner is aligned with the longitudinal axis and the rear of the axle stub ( 14 ) is arranged. For this purpose, the stub axle ( 14 ) an example central threaded hole ( 16 ), in which the bearing journal ( 25 ) can be screwed.

If the stub axle ( 14 ) through the lever end ( 12 ), the journal ( 25 ) directly in the threaded hole ( 16 ) are screwed. Otherwise, the lever end ( 12 ) a passage opening for the bearing journal ( 25 ) exhibit. The threaded hole ( 16 ) can also be the lever end ( 12 ) and enforce the axle stub together.

The bearing journal ( 25 ) bears outside the bearing eye ( 23 ) and forms with this the camp ( 21 ). Both bearings ( 21 . 22 ) are multiaxially movable, whereby the shock absorber ( 20 ) in the 1 shown manner can be issued obliquely and about a substantially horizontal axis of both bearings ( 21 . 22 ) can turn.

For mounting on the chassis ( 2 ) is a bearing block ( 24 ) present, the z. B. at the bottom ( 4 ) of the longitudinal member ( 3 ) is arranged. The warehouse ( 22 ) is located below the longitudinal member ( 2 ).

As 2 and 3 clarify, this storage location is located with the warehouse ( 22 ) and the axis ( 7 ) on opposite sides of the wheel axle ( 18 ) or the stub axle ( 14 ). In other words, in the direction of travel ( 26 ) saw the camp ( 22 ) in front of the wheel axle and the axle ( 7 ) arranged behind the wheel axle. The wheel swing lever ( 11 ) and the shock absorber ( 20 ) are thus directed against each other.

In the in 2 illustrated normal driving position under normal load and with rebounded wheel ( 18 ) close the obliquely downward longitudinal axes of the Radschwinghebels ( 11 ) and the shock absorber ( 20 ) an obtuse angle with each other, the z. B. between 90 ° and 180 °. The arrangement is similar to a toggle. When compressing the wheel ( 18 ) is the taking or approach to an extended position according to 3 possible, in which the two longitudinal axes are approximately aligned. During compression, the shock absorber ( 20 ) and can be loaded on pressure. If the immersion depth of the shock absorber ( 20 ) is limited, the spring travel of the wheel ( 18 ) are limited by damper stop, which, if necessary, before reaching the stretch or escape position of 3 is possible.

The shock absorber ( 20 ) may be formed in any suitable manner. It may be a pneumatic and / or hydraulic shock absorber or any other and preferably linear damper construction. In particular, the shock absorber ( 20 ) be designed as a double tube damper, wherein the thicker outer tube z. B. on the chassis side bearing ( 22 ) and the thinner tube with the piston rod over the bearing ( 21 ) with the wheel swing lever ( 11 ) connected is. As 1 in the plan view, the shock absorber ( 20 ) optionally obliquely through the lateral clearance between the outside of the longitudinal member ( 3 ) and the adjacent vehicle wheel ( 18 ) or the associated Radschwinghebel ( 11 ).

Modifications of the embodiment shown and described are possible in various ways. The formation and geometry of the axis ( 7 ) as well as the suspension ( 10 ) can be designed differently. With a torsion spring axle, the axle shafts ( 9 ) and form a torsion bar construction. The shock absorber ( 20 ) can be used on other parts of the chassis ( 2 ) and the wheel-side lever end ( 12 ) attack and be stored. In the embodiment shown, the hub ( 17 ) has a drum shape and is suitable for the installation of a drum brake.

Alternatively, the hub ( 17 ) have a different design and for other brake designs, z. B. disc brakes, be designed. On a wheel brake can be dispensed with in a further modification. The hub ( 17 ) can be reduced to a wheel bearing plate. Furthermore, the orientation of the shock absorber ( 20 ), with its chassis-side pivot point to the axle ( 10 ) and possibly in the area between the stub axle ( 14 ) and axle tube ( 8th ) lies.
