Abstract: A device for damping vibrations acting on a tracked vehicle is provided, which has a front and rear track roller. Torsion springs are mounted along a vehicle pan. Alternatively, the torsion springs can be subdivided into smaller torsion springs. For the immediate track rollers, a further device is provided in which the long torsion springs which hitherto absorbed the torsion are divided into a plurality of smaller torsion springs and mounted not transversely with respect to the vehicle pan, but in a direction of travel with respect thereto. The torsion springs are functionally connected to one another via drive and/or transmission elements, and are accommodated outside an interior space. In this way, no further installation space is required transversely with respect to and below the vehicle pan, at most in the side region or within a small recess in the pan, a so-called pan niche.

Abstract: A device for increasing the magnetic axial force of the displacement type armature motor in motors is provided. The device comprises an iron ring (10) furnished with an outer chamfer (11) matching with the conical course of the rotor (6). The spring-loaded pretensioning of the iron ring (10) suffices for the attachment of the brake support casing (7) on the support ribs (8). The iron ring can be permanently and reliably attached to the rotor motor at low expenditure.
