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

Moveable track connection

The present invention relates to a kind of moveable track connection (Gleisverbindung) by claim 1.

Such moveable track connection both had been used for vehicle switching tracks on the adjacent lines Car Track, and the track that also is used between two terminations of same Crane Rail connects.

In DE 4416819C2, introduced a kind of branch-cut bridge, wherein each track end can be from the end direction elastic buckling of a bent beam to adjacent orbit, its flexible end can align mutually, forming branch-cut bridge, but and the beam of the end adjacency of the elastic buckling of itself and bent beam can deviate from the outside elastic buckling of adjacent orbit.Here both must to have made two track outer ends outwardly-bent in order switching on the adjacent track, and two track end to have been curved inwardly in order to switch tracks.Need many bending apparatuss, they must realize the motion of different sizes at different points for this reason.

By the known a kind of transition linkage between the track of the vehicle that (fahrwegumgreifende) that surround rail mounted, track guide of DE 19631324C1, the wherein same crooked track switch that has the movable rail element that has many same types, these orbit elements are parallel to each other and distribute and interconnect by many Connection Element mechanical articulation or by logic function.Even in this transition linkage, also carry out respectively and handle at least four track end as crooked track switch.

Introduced the device that switches tracks that is used for magnetic suspension train rail among these external two parts of document DE 19800908C1 and the DE 19800909C1, wherein for the device that switches tracks is installed, the end of relevant track is made bent beam, and the skew of outer tie-beam does not have the shifting ground and carries out.The swivel bearing that exists between the track of standard and switching element for this reason, they can be locked, to produce bending.

Belong in the prior art constructions this, the end of two crooked track switches interconnects respectively, and the connection of the crooked track switch of two backward bearers here is problematic, and needs the bigger expansion clearance of cross-over connection.Bridge joint for this expansion clearance adopts bascule bridge (Klappbruecke) especially.

The objective of the invention is, recommend a kind of moveable track connection, do not have the problem of being mentioned in this branch-cut bridge, and particularly avoid joining the discontinuity at position.

In claim 1, provided the scheme that achieves this end.Dependent claims 2 to 6 is favourable form of implementation.

According to the present invention, but a crooked track switch that has the S deformation shape that is used to switch tracks of so-called curvature conversion is only adopted in suggestion, and it has the bearing of a band vertical rotation axis on half extension position, and bearing can not move at the length direction of crooked track switch.The special advantage of the scheme that the present invention recommends is, needn't resemble in the prior art with end (floating bearing) locking mutually of two crooked track switches, and only need the end of a crooked track switch is locked with respect to the fixation ends (rigid bearing) of track.Because the expansion clearance, two ends that floating bearing is assigned to crooked track switch obviously reduces, the bascule bridge that therefore is used for the cross-over connection expansion clearance can design simplyr and be littler, perhaps even fully phase out.Avoid the effect owing to temperature and vehicle in addition fully, the discontinuity when conversion in bending line perhaps obviously reduces with respect to present existing scheme.Owing to only adopt a crooked track switch, compare with structure up to now and also cancelled a rigid bearing in addition.

Describe the present invention for example in detail by means of accompanying drawing 1 to 4.Accompanying drawing is represented:

D) in the position that switches tracks from second of the middle position b)

In the drawings, crooked track switch 1 is rendered as straight line on the one hand and connects, and is rendered as the S shape with differently curved direction on the other hand.Crooked track switch 1 is connected with the end of track 3 by termination bearing (widerlager) 2 respectively.Crooked track switch 1 has a rigid bearing 4 at half length place in Fig. 1, and it is on the center line between two tracks 3 that are provided with in parallel to each other.Press Fig. 1 a), fixed point 7 to 10 is used for producing S shape bending line.By Fig. 1 b) during back-flexing they be fixed point 7 ' to 10 '.

Replace being provided with so-called two bearings (bivalente Lager) 6 by the rigid bearing 4 of Fig. 1 in Fig. 2 to 4, use this bearing, crooked track switch 1 vertically can be moved perpendicular to track.For press Fig. 2 a), 2b), 3a) with 4a) track be connected, and press Fig. 2 d for setting up), 2e), 3c), 3d), 4c) and the crooked track switch of S shape 4d), these two bearings 6 are correspondingly locked certainly.

The expression duplicate rows is sailed the schematic diagram of track situation in Fig. 2 and 3, its quantity of expression can enlarge arbitrarily in Fig. 4, the schematic diagram of three parallel orbits for example.Fig. 3 also expresses a trave lling girder 5 in addition, it by Fig. 3 a) have the track linkage function, by Fig. 3 b) to d) outwards move abreast, provide the position to give the transversely movable crooked track switch 1 that will move to the centre position.

The fixing point 7 '-10 ' be used for of S shape sweep that 6 two bearing 7-10 of crooked track switch 2 termination bearings, 3 track 4 rigid bearings, 5 trave lling girders of pictorial symbolization table 1 are used for producing the crooked track switch 1 of the vicissitudinous curvature of tool produces the fixing point of S shape sweep of the crooked track switch 1 of the vicissitudinous curvature of tool
