Definitions

• the invention relates to a storage system for traffic routes with support units supported on a substructure, in which high deformation speeds occur due to traffic loads.
• the invention further relates to bearings that are used in the bearing system according to the invention, in particular one-way linear tilt slide bearings, all-round movable linear tilt slide bearings, linear tilt bearings for use as fixed bearings for absorbing lifting forces, push-pull tilt bearings for use as fixed bearings without lifting forces and devices for height adjustment the bearings that are used in the above-mentioned storage system.
• the support units can be, for example, so-called single-span beams with four supports, two-span beams with six supports or multi-span beams, while the substructure, for. B. from the substructure of a suspended or elevated bridge for traffic routes, the elevated route or arranged on the ground route of trains, in particular high-speed trains.
• High-speed railways which reach speeds of the order of 400 to 500 km / h, work on the principle of electromagnetic levitation, which is based on the attractive forces between the rails in the track and the electromagnets, which are arranged in a band on the right and left along the track. If the onboard magnets arranged on board the vehicle are switched on, this becomes Vehicle pulled against the rails from below. A control and regulation system on board the vehicle controls the change in the air gap, which decreases with increasing attraction. It must be ensured that an air gap of approx. 10 mm is maintained. Considerable requirements are therefore placed on the design and storage of the guideway.
• the track consists of a route which is formed by individual track supports which r is strung together on a substructure, wherein the substructure consists of a foundation arranged on the ground or at an elevated guideway construction stands.
• the guideways have rails or stator packs with windings for carrying, guiding and driving the magnetic levitation railway, facilities for energy transmission, switches and, in the case of an elevated arrangement, the supporting structure, supports and foundations, as well as a special supporting plate construction when arranged at ground level.
• the elevated chassis construction is preferred, with prefabricated parts made of concrete or steel being used.
• expansion joints of up to 100 mm can be easily run over due to the interaction between the vehicle and the track, it must nevertheless be ensured that in the area of the joints between two adjacent track beams, a vertical or lateral offset of the individual beams to one another is absolutely avoided.
• the vibration behavior is problematic in single-span girders in that they tend to bend, so that in the expansion joint area there is a narrowing on one side and an enlargement of the expansion joint on the opposite side.
• driving over the girder with a magnetic levitation train at high speed leads to the girder executing an approximately sinusoidal oscillation around the central support, so that due to the rotation of the guideway girder, the sliding surface or the bearing parts move and tilt towards one another.
• the prescribed shifting and tilting movements take place in extremely short periods of time and can be up to 15 to 20 mm per second for a 50 m long guideway girder. Very high demands are therefore placed on the storage system of a guideway girder.
• the wear caused by the combination of the effects of displacement speed and pressure should be kept as low as possible, so that efforts are made to keep the friction between the surfaces sliding on one another as small as possible.

The special contraction of the linear tilting bearing will be discussed later.
• the bearing system for a guideway carrier further comprises at least one line-tilt sliding bearing that can be moved on all sides per bearing axis. This type of bearing allows sliding movement in the longitudinal and transverse directions as well as tilting movement in the longitudinal direction of the carrier unit.
