It is an object of the present invention to provide a vehicle body with a different and improved adjusting device for a self-aligning bearing and a vehicle with a vehicle structure of the designed.

The invention solves this problem with the features in the main claim and in the independent claim 20.

The claimed design of the self-aligning bearing and the adjusting device has the advantage of high mechanical stability and deformation resistance. The pendulum board can be stored, supported and guided better.

The adjusting device can be used for adjusting the pendulum bearing and the position of the pendulum tailboard on the container structure. For this purpose, a side wall adjustment in one direction suffice, for. B. along or obliquely to the body or horizontal.

As a result, the pendulum board can be employed or pressed transversely or obliquely to its main plane to the vehicle body, in particular on the side walls in the closed position. This is particularly advantageous for tensioning and adjusting wall seals which ensure a tight closure of the swing-side wall on the vehicle body, in particular on a dump body. On the other hand, the correct functional position can be adjusted in relation to a locking of the swingboard in its closed position.

The claimed adjusting device is more ergonomic than in the prior art. It is also easier and easier to use. In addition, only a small amount of force is required. It suffices a lifting or lowering, whereby the hand force can be supported by leverage. The lifting force and lifting movement on the adjusting device can be deflected and used in a pressing movement of the pendulum liftboard to the container structure.

The self-aligning bearing and adjusting device can be directly attached to the vehicle body, e.g. be arranged on a side wall, or on a pivoting device for the pendulum board. The latter is particularly advantageous for dump trucks in which in tilting the pivoting device lifts the pendulum liftboard and thereby increases the rear-side body or trough opening for the discharge of cargo.

In the subclaims advantageous embodiments of the invention are given.
