Abstract

The invention relates to a moveable track connection between the ends of travel paths for wrap-around track-guided vehicles, especially magnetic levitation railway vehicles, comprising a set of S-shaped deformable bending points (1) for changing track, which has a bearing (4,6) along half the length thereof with a vertical axis of rotation, which cannot move in the longitudinal direction of the bending points (1).

Description

The invention relates to a movable track connection according to Claim 1.

Such movable track connections serve both for changing lanes Vehicle on the neighboring route as well as a track connection between the two ends of the same route.

DE 44 16 819 C2 describes a track connection in which each End of track from a bending beam towards the end of the neighboring one Track is elastically bendable, the bendable ends to form the Track connection can be aligned in alignment with one another and whose elasticity bendable end of the bending beam adjacent beam from the adjacent one Travel path is elastically bendable away to the outside. For changing lanes on one The adjacent route must have both the two ends of the route both the outside and the two ends of the track for changing lanes be bent inwards. For this a variety of bending devices needed, the movements of different sizes at different points have to perform.

From DE 196 31 324 C1 a transfer connection between routes for Track-leading, track-guided vehicles are known, also Bending points with several similar movable guideway elements are present, which run parallel to each other and by several Connecting elements articulated mechanically or logically functional with each other are connected. With this transfer connection, too, at least four guideway ends designed and operated as bending points.

In the two documents DE 198 00 908 C1 and DE 198 00 909 C1 are also Lane changing devices for routes of a magnetic levitation train are described, the ends of those involved in the construction of the lane changing device Roadways are designed as bending beams and the shifting of the outer Connection carrier is carried out without deformation. For that are between the normal Guideway and the transition elements pivot bearing present, leading to bending can be locked.

In these versions belonging to the prior art, the Ends of two bending points connected to each other, the connection of the both oppositely loaded bending points is problematic and a relative large expansion gap is to be bridged. For this expansion gap bridging special bascule bridges used.

The invention has for its object a movable track connection to propose where the above problems do not exist and in particular discontinuities at the transition points can be avoided.

The solution to this problem is specified in claim 1. The Sub-claims 2 to 6 contain reasonable embodiments.

According to the invention, the use of only one for changing lanes is S-shaped deformable bending switch with so-called change of curvature proposed, which has a half-length bearing with a vertical axis of rotation, which in Longitudinal direction of the bending point is not movable. The special advantage of Proposal according to the invention is that not as in the state of the Technique two bending point ends (floating bearing) can be locked against each other need, but there will only be one end of a bending point compared to the fixed end (fixed bearing) of the track locked. By dividing the Non-locating bearing on the two ends of the bending point, the expansion gap becomes significant reduced, so that the bascule bridges for bridging the expansion gap are easier and can be made smaller or even eliminated entirely. Also be Discontinuities in the bending line during the transition due to temperature and Vehicle impact largely avoided or compared to the previous ones Solutions significantly reduced. By using only one bending switch it also follows that compared to the previous statements Fixed bearing is not applicable.

In the figures, the bending switch 1 is on the one hand a straight track connection and on the other hand, S-shaped with different directions of curvature. The bending point 1 is in each case via an abutment 2 with the ends of the travel paths 3 connected. In Fig. 1, the bending point 1 has the fixed bearing 4 at half the length, that on the center line between the two arranged parallel to each other Routes 3 lies. Serve to generate the S-shaped bending line Fig. 1 a) the fixed points 7 to 10. With the opposite curvature after 1 b) these are the fixed points 7 'to 10'.

In Figures 2 to 4 is a so-called instead of the fixed bearing 4 of FIG. 1 bivalent bearing 6 is provided, with which the bending point 1 transversely Longitudinal direction of the route is displaceable. For the track connection after the Figures 2 a), 2 b), 3 a) and 4 a) and for the production of the S-shaped The bending point according to FIGS. 2 d), 2 e), 3 c), 3 d), 4 c) and 4 d) becomes this bivalent Bearing 6 of course locked accordingly.
