DE102007042263A1 - Molded roadway body, especially for magnetic levitation track, has prismatic oblong base body with 2 side walls, 2-part top whose parts form longitudinal opening in center parallel to side walls while two ends of molded body are open - Google Patents

Abstract

The body (1) has a prismatic oblong base body (10) with two lateral walls (8,9) and a two-part top (7), whereby the two parts form a longitudinal opening (11) in the center that lies parallel to the lateral walls while the two ends of the molded body are open. The molded body is of steel-reinforced concrete.

Description

object The invention is a guideway shaped body, in particular for a magnetic levitation train.

Known Routes for Magnetic levitation trains cause loud operation, such as at the Transrapid, in which the drive function of the magnetic fields with the support function is mixed and the sound emission to the sides can not be prevented.

task The invention is to improve the state of the art, in particular a cost-effective and quiet driveway for Magnetic levitation trains available to deliver.

The Task is solved by the invention.

The subject of the invention is guideway shaped bodies ( 1 ), an elongated prismatic body ( 10 ), which has two lateral walls ( 8th . 9 ) and a two-part ceiling ( 7 ), wherein the two parts of the ceiling in the middle of a longitudinal opening ( 11 ), which runs parallel to the lateral walls, while the two ends of the molding are open.

2 shows the track mold according to the invention with a vehicle.

3 shows a special embodiment of the guideway shaped body according to the invention.

Preferably, the guideway shaped body ( 1 Made of iron or preferably made of reinforced concrete with appropriate strength, preferably about 3 m long (with respect to mounting weight and curve radii) and suitable to be connected either on existing tracks with many such parts to the track, or other planed and paved areas (roads) laid one behind the other to form a track, or even as a crown of a concrete wall (or other supporting structure) to form the track. In this case, the length of the parts vary and the production also take place completely or partially in Ortbetonierungsverfahren.

Decisive is the cross section (see also the figures). Apart from the size of the cross-section is about the same as an inverted curtain rail. The tracking of vehicles ( 13 ) is preferably carried out by magnetic forces. Any vehicles ( 13 ) - useful in lightweight construction, as in principle no derailment is possible - can be used if they instead of wheels continuous or interrupted or over the entire length continuous preferably T-shaped feet ( 12 ), which are preferably made of metal, in which the magnetic coils are mounted for carrying, which generate left and right and top and bottom controllable magnetic fields, which with approximately 10 mm air gap the Waggonfuß (feet) in the middle and without contact in the air and thus lift the entire wagon (wagons) and make it mobile. The distance control must and can with appropriate Bordelektrischen means from the wagon ( 13 ) and does not require too much energy, even at high forces. It is important that the metal rails on the two-part ceiling ( 7 ) at each ceiling part at least one metal rail ( 2 ) or preferably metal rails symmetrically to the metal rails on the ceiling also two metal rails ( 3 ) on the base body ( 10 ), ie just under the metal rails in the ceiling, have, according to the effective forces (wagon weight!) Strongly fixed or embedded in concrete.

The guidance of the vehicle ( 13 ) (vertical and horizontal) on the track according to the invention is not bound to any particular type of drive. Magnetically carried and guided vehicles could be powered by linear motors, propellers or recoil motors, possibly even with sail surfaces or friction wheels.

In the case of linear motor drives, the drive solenoid coils ( 4 . 5 ) laterally, on the lateral, preferably vertical walls ( 8th . 9 ) inside the guideway body, mounted, which together with corresponding components in the waggon foot ( 12 ) laterally at least on the left or right form a linear motor. Preferably, both lateral walls ( 8th . 9 ) Drive solenoid coils ( 4 . 5 ) on. Analogous to the Transrapid system, the acceleration, advancement and deceleration of the wagon 13 ) occur. In contrast to the Transrapid but the drive function of the magnetic fields is not mixed with the support function, making the control is much easier. The forces of the linear motors left and right act only horizontally (or in the plane transverse / longitudinal track).

In one embodiment, the steel rails ( 14 ) are mounted on both edges of the ceiling opening as U-profiles, so that to the left and right or vertically directed forces can be effected by appropriately attached active, controllable coils on the vehicle.

The advantages of the guideway molding according to the invention are that railway tracks (without track) can be built by using as Constructions on existing railway lines are formed or laid on leveled tracks directly on the ground (gravel) or arranged as a crown on other supporting structures.

These Trajectories have the following characteristics: On them you can use wheelless, carrying, guiding and carrying light wagons by means of magnetic forces accelerate, while at the same time providing constructive security against derailment. High speeds (more than Transrapid) are possible, the Noise emissions are still very low.

The lateral left / right balancing forces between the fixed and moving part of the Liearmotors can be made very large and larger than "m × g", ie the wagons can be accelerated or braked with more than 10 m / s ² .

One Another advantage is that the construction costs for these novel routes not with the guideway moldings according to the invention are higher as about the cost of conventional rail lines. For new buildings you only need planum and per kilometer about 300 parts (prefabricated incl. Linear motors for mating), however, no track, no Gravel, no overhead line. In operation is much less Energy consumed per passenger kilometer, especially because at every start a lightweight train with about 1/3 of the mass of a conventional Railway train only 1/3 as much energy needs.

Finally, points the novel driveways a "built-in Sound insulation ". The sounds, which aerodynamically generated at the air gaps, can only radiate upward and this is diminished by the fact that at the moment of creation of sound the car body is above it.
