Definitions
- the invention relates to a switch arrangement of the type specified in the preamble of claim 1.
- a switch arrangement of the type of interest here consists of a so-called flexural switch (eg "Maglev Transrapid - The New Dimension of Travel, Hestra-Verlag Darmstadt 1989, pages 32 to 35, DE 10 2004 015 495 A1)
- Biegeweiche is a bendable, existing steel support, for example, 50 m long or longer and carries the track or equipment of this .
- the carrier is arranged at one end stationary and the rest by means of several support point and on These mounted wheels are movably mounted on rails, which are arranged transversely to their longitudinal direction, which is also the direction of travel.To set the switch, the support frames can be moved back and forth along the rails, whereby the beam is bent and optionally to one of several, is aligned by the turnout branching roads.
- the turnout arrangement designated dry slide bearing, by means of which the carrier is supported on the supporting frames and allow the required axial and rotational movements between the carrier and associated parts of the supporting frames.
- the provided on both sides with flanges, on the rails mobile guided wheels prevent movement of the supporting frames parallel to the direction of travel, while the plain bearings allow expansion or compression of the carrier relative to the support frames in this direction.
- the engine does not rotate about the drive shaft in the switched-on state, it is supported by means of at least one support element on the carrier, wherein between the motor and the carrier another dry sliding bearing is provided which allows movements of the carrier relative to the motor.
- the carrier supporting the sliding bearing have several functions. Not only do you have to carry the weight of the wearer, but you must also allow relative movement between the wearer and the support frames. As a result, comparatively long and stable bearings must be provided, which is why the existing of the carrier and the support frames overall device is relatively complicated and expensive. Since the carrier can also be comparatively large in all three dimensions, with high temperature fluctuations and in particular with uneven solar radiation, comparatively high stresses can occur in the carrier, which distribute the loads correspondingly unevenly to the plain bearings. This can lead to very high local loads of plain bearings, in extreme cases to a blocking of the bearings and also to a strong noise in the plain bearings. The service life of the plain bearings may be considerably shorter.
- the technical problem of the present invention is to design the switch assembly initially described in such a way that the plain bearings between the carrier and the supporting frames omitted.
- the characterizing features of claim 1 serve.
- the invention has the advantage that the carrier, the support frame and the drive mechanism exert no movements relative to each other, but in thermal expansions or compressions of the wearer simply join in these movements. Instead, the wheels on the rails and the gears in the racks are parallel to the direction of travel displaced, so that it can not come to unwanted voltages in temperature fluctuations.
- the solution according to the invention has the consequence that, due to the slidable mounting of the wheels on the rails and the gears in the racks, any irregularities which can result are compensated by the fact that the rails and racks do not always run along paths which are exactly the same the slightly different from circular paths trajectories of the associated sections of the carrier during the bending process accordingly.
- FIG. 3 is a schematic plan view of a switch arrangement according to the invention.
- Figures 4 and 5 are schematic and rotated by 90 ° cross-sections along the lines IV-IV and V-V of Fig. 3;
- FIG. 6 shows a schematic side view of the switch arrangement according to the invention in the direction of an arrow v of FIG. 3;
- Figure 7 is a schematic plan view of two supports of the switch assembly of Figure 6 omitting a carrier and of support frames for this.
- Fig. 8 is a greatly enlarged longitudinal section through a support frame according to Fig. 6 and a Drive mechanism of the switch assembly according to the invention.
- a conventional switch assembly in the form of a bending weir for magnetic levitation trains includes a bendable, made of steel and over the entire length of the switch stretched carrier 1, the z. B. about 50 m long or longer.
- the support element 2 contains, as shown particularly in FIGS. 4 and 5, two arranged in the installed state substantially vertically and perpendicular to the ground web plates or side panels 3. Between the side members 3, the stiffening serving transverse walls or bulkheads are provided.
- each side part 3 are projecting from it cantilever arms or support plates 4 are fixed at the ends parallel to the side members 3 extending and vertically mounted in the installed state webs 5 are attached.
- the direction of travel of the vehicles along the carrier 1 and its longitudinal direction is generally referred to as the x-axis of an imaginary coordinate system, while the transverse thereto extending direction (width) in which the support plates 4 are extended, as the y-axis and the two axes vertical direction (height) as the z-axis of the imaginary coordinate system is considered.
- a side guide rail is provided on each longitudinal side of the bending beam 1, wherein the arrangement is preferably mirror-symmetrical to a plane parallel to the xz-plane of the imaginary coordinate system center plane.
- the carrier 1 On the upper side of the carrier 1 or a cover plate 7 supported by the latter and the support plates 4, two further pieces of equipment in the form of slide strips, not shown, are attached, preferably likewise mirror-symmetrical to the median plane, which serve for depositing the vehicles and are like the equipment 6 extend over the entire length of the carrier 1, in contrast to these but in the installed state substantially are arranged horizontally.
- the carrier 1 is provided on the underside of the webs 5 with equipment parts 8 in the form of stator carriers, which may consist of transversely to the webs 5 and equipment 6 arranged plates or blocks and z. B. are used to attach the stator of a long stator linear motor.
- the described parts 1 to 8 are made of steel and are connected to form the apparent from Fig. 1 to 6 apparent support 1, preferably by welding inextricably.
- the carrier 1 for adjusting the switch assembly z. B. from a continuous infrastructure section A on a branching infrastructure section B continuously to a maximum of z. B. bent about 3.65 m.
- the carrier 1 on z. B. supports six anchored to the ground supports 9 to 14, wherein one end Ia (eg., Fig. 1 and 6) of the carrier 1 in a manner not shown with a first support, here the support 9, is firmly connected while other portions of the carrier 1 on the other supports 10 to 14, z. B. the support 10 of FIG. 3 and 5, transversely to the longitudinal direction and can be moved substantially horizontally back and forth.
- the wheels by means of 16 is mounted on rails 17 mobile. The weight of the carrier 1 is therefore supported by the wheels 16 and the rails 17.
- the rails 17 are, such. B. Fig. 7 in a plan view without carrier 1 and support frame 15, arranged on the respective supports 10 to 14, extending substantially in the y direction and thereby formed slightly curved.
- the respective curvature of the rails 17 is defined according to the constructed bending curves of the carrier 1, d. H. essentially dimensioned according to those paths along which the supported on the associated supporting frames 15 sections of the carrier 1 move when it is bent at fixed end Ia by movement of the respective supporting frames 15 in the y direction.
- This contains an approximately parallel to the drive or longitudinal drive shaft 19 which is fixedly connected at one end with a gear 20 and at the other end via a coupling 21 with the output shaft of a motor 22, in particular an electric motor.
- the gears 20 of the various drive mechanisms 18 are each engaged with a rack 23 (FIG. 8) which is arranged transversely to the direction of travel and substantially parallel to the relevant rail 17 (FIG. 7).
- the racks 23 have a curvature substantially corresponding to the associated rail 17 and are fixed to the undersides of a respective support plate 24 ( Figure 8) mounted by a stand 25 mounted on the support (eg 10) and rising therefrom will be carried. Therefore, if the motors 22 are turned on and the drive shafts 19 in one or the other direction of rotation set in rotation, then roll the gears 20 on their associated racks 23 and thus move, as explained in more detail below, the associated supporting frames 15 and with them the resting on these portions of the carrier 1 in the y direction. As a result, the carrier 1 is bent in the manner shown in FIG. 2 and set to one of the at least two travel paths A and B respectively.
- At least one support frame 15 is required for adjusting the switch assembly, which is displaceable in the manner described transversely to the direction of travel.
- a plurality of such support frames 15 is usually provided depending on the length of the carrier 1. All of these supporting frames 15 and the units required for their displacement can be formed substantially identically, so that only those assemblies which are associated with the support 10 will be explained in greater detail below with reference to FIG. 8.
- z. B. Fig. 3 that in the embodiment on both sides of the carrier 1, two identical drive mechanisms 18 are provided, each having an impeller 16 of the respective
- the carrier 1, the support frame 15 and the drive mechanism 18 mounted in the support frame 15 form a rigidly interconnected structural unit which is displaceably arranged in the direction of travel (x-axis) as a whole relative to the rail 17 and the rack 23.
- the rail 17 by means of fasteners 26 and the rack 23 fixed by means of the stator 25 rigidly and immovably to the associated support 10.
- each impeller 16 does not have a double flange wheel arranged on both sides, but only a smooth, preferably cylindrical, slightly conical or spherical surface 27.
- the impeller 16 can roll not only in the y-direction on the rail 17, but also transversely to it, ie in the x-direction, with sliding friction on the rail 17 are moved.
- the flanks of the gear 20 and the rack 23 are formed so that the gear 20 can make a possible displacement of the impeller 16 in the x-direction by also moves in the rack 23 in the x direction. The purpose of these measures is explained below.
- the support frame 15 includes a hollow shaft 28 with a parallel to the x-direction extending central axis 29.
- the hollow shaft 28 extends through a hub 30 of the impeller 16 coaxial and is rotatable with this hub 30 by means of other fasteners 31 and axially and radially firmly connected, so that relative movements between the impeller 16 and the hollow shaft 28 are not possible.
- the support frame 15 has, according to FIG. 8, a frame or mounting part 15a fastened to the underside of the carrier 1 and carrying two bearing sections 32 spaced apart in the x-direction, which are arranged on both sides of the running wheel 16.
- These bearing sections 32 consist z. B. from housings of thrust bearings 33, in which both sides of the impeller 16 arranged portions of the hollow shaft 28 are rotatably mounted.
- the thrust bearings 33 are preferably formed as a self-aligning bearing, the carrier 1 and the hollow shaft 28 axially (x-direction) firmly and immovably interconnect, relative rotational movements and even slight oscillations between the carrier 1 and hollow shaft 28 but allow. As a result, possible deformations of the carrier 1 due to uneven temperature distributions can be compensated.

- axial slide bearings 36 are provided which cooperate with stepped portions 37 of the drive shaft 19 and are closed to the outside by further cover. Therefore, the arrangement as a whole is such that the hollow shaft 28 and the drive shaft 19 are indeed connected axially non-displaceable, but rotatable with each other.
- the motor 22 is axially immovable by means of a support 38 and rotatably connected to the carrier 1 or connected to this mounting part 15 a. As a result, on the one hand rotations of the motor 22 about the central axis 29, on the other hand axial relative movements between the motor 22 and the carrier 1 are prevented.
- the carrier portions affected by thermal expansions or compression can be combined with the drive mechanisms 18 (in particular formed from the gear 20, the drive shaft 19 and the motor 22) and with the support frame 15 (in particular formed from the hollow shaft 28, the impeller 16 and the thrust bearing 33) move in the x direction, so that no relative movements between these modules are required.
- the widths of the impeller 16, the rail 17, the gear 20 and the rack 23 are preferably selected so that even with extreme thermal expansion or compression of the carrier 1 is always a complete contact between the parts 16, 17 and 20, 23 is guaranteed.
- the invention is not limited to the described embodiment, which could be modified in many ways. This applies in particular to the construction described with reference to FIG. 8.
- Another variant could be that the motor 19 mounted in Fig.
- the carrier 1, the support frame 15 and the drive mechanism 18 each form a displaceable as a whole relative to the rail 17 and the rack 23 assembly, so that the axial position of the support frame 15 and the drive mechanism 18 through the support 1 and not as previously determined by the rail 17.
- per support 10 to 14 and per support frame 16 more than one impeller 16 may be provided, such.
- Fig. 3 to 5 show, after which two wheels 16 are available. It is possible to assign each impeller 16 has its own drive mechanism 18, the gears 20 could engage in the same or different racks 23.
- two or more supporting frames 15 may be present, which have on the same or on different rails 17 rolling wheels 16.
- this formulation also includes the presence of two or more corresponding parts.
- a guide rail 39 is mounted on the underside, which defines the defined plane, a roller mounted on the drive shaft 19 pressure roller 40 rolls.
