Abstract: The invention relates to a spring element for vibration damping and/or suspension of a rail vehicle, comprising at least one elastic damping body and at least one fire-resistant cover layer arranged on the damping body, the cover layer having at least one compensation zone, wherein the compensation zone is compressed in the loaded state of the spring element such that wrinkling of the cover layer is prevented, wherein the cover layer and the damping body are inseparably connected to form a composite element. The invention further relates to a cover layer and the use of a spring element or a cover layer.

Abstract: The invention relates to an article, more particularly an air spring bellows, having a one-layer or multi-layer main body with elastic properties, at least one layer of the main body being made up of a rubber mixture, a carbon black proportion of at least one carbon black, more particularly a total carbon black proportion of all carbon blacks, of the rubber mixture being less than 5 phr. The rubber mixture preferably contains aluminium hydroxide as a reinforcing filler. The rubber mixture can comprise chloroprene rubber as a base polymer.

Abstract: A connecting sleeve suitable for the production of a push-pull link bar includes a main body, a coupling section which is formed or arranged on the outer circumferential side on the main body, and a through bore, characterized in that the connecting sleeve has a first seal which is arranged at least partially on the outer circumferential side and a second seal which closes at least the through bore.

Abstract: A fail-safe push-pull rod has two load paths that are separated from each other, of which always only one takes up the load transmission and which automatically detects possible damage to or functional failure of the first load path so that in such a case then the second load path takes over the load transmission, whereby the functional change from the first to the second load path can be determined during the routine maintenance inspection by an inspection hole irreversibly showing the damage or the failure of the first load path.

Abstract: Draw-pull bar used for guidance and mechanical mount with a locking mechanism consisting of two locking elements, namely a securing clip with a locking nose shaped as partial ring that is arranged on the toothed ring of the tubular body of the draw-pull bar by means of swivel arm and in which the locking nose engages when the securing clip swivels to the toothed ring. A bar with a hinge is fitted to one side of the resilient partial ring. When using a locking element, the bar snaps into the other end of the partial ring in such a way that the partial ring is clamped tight and an unintentional turning or undoing of the two locking elements is prevented without previous opening of the bar.

Abstract: A draw-pull bar is described which consists of at least one adapter with a metallic tubular end and of an inner and outer tubular body out of carbon-fiber-reinforced plastic (CFRP). It is characterized thus that the outer CFRP tubular body conically wraps the metallic end of the adapter from the outside in a form-fit manner while the inner CFRP tubular body is form-fit connected with the metallic ends of the adapter. An elastomeric layer is tapered in the contact area between the inner tubular body and the outer tubular body in such a way that both tubular bodies are separated on the one side, but are arranged against each other in a protected and damped manner on the other side.

Abstract: A threaded device is embodied in the form of an anti-twisting stop which is rotatably connected to a traction-pressure rod. Two oppositely located ratchet devices are connected by a body to stop the traction-pressure rod in several rotational positions with a predetermined locking force and, afterwards, to release it each time. The threaded device facilitates the mounting of the traction-pressure rod by the fact that the twisting should not be locked by additional handling, thereby making it possible to carry out a fine adjustment without additional measures. The ratchet device comprises, for example, two ratchet elements provided with one or several catch lugs or a metal or plastic ring part on one side and a gear rim on the other side. In addition, the threaded device can be provided with a spring element and a second anti-noise threaded device.

Abstract: The invention relates to a resilient, multi-component wheel for rail vehicles, comprising a rim (2) and hub (11) as well as an elastic element (6, 8) removably inserted between said rim and hub. Said elastic element (6, 8) is configured as a concentric, separate part consisting of a central disk (7), two larger outer disks (5, 9) and two elastomer rings (6, 8) positioned between said disks. Said elastomer rings (6, 8) are made of a plastic material or rubber, can have different shapes depending on the desired type of compressive stress or shear stress and are connected to the disks (5, 9) in a non-positive manner.
