Abstract

PURPOSE:To reduce the cost of a linear motor upon installation of secondary conductors by providing composite secondary conductors only in sections which sufficiently require drive forces by a linear induction motor. CONSTITUTION:Rails 6 are installed between stations A and B, and train 5 departs from the station A and travels to the station B. Composite secondary conductors 3 are installed only in the necessary sections of the sections, through which a train 5 travels. For example, the composite secondary conductors 3 are installed only in the prescribed section C, where the train travels from the station A to the station B and in the prescribed section D beforehand from the station B, and the secondary conductor is not installed in the section E between the sections C and D. The train 5 idly travels in the section E.

Description

[Detailed Description of the Invention] IN Ming relates to a linear motor device for a vehicle using an on-vehicle primary type linear induction motor as a drive source,
The method of installing the secondary conductor on the opposite side.

A linear motor is used as the driving source for the propulsion of one car and the other. So-called linear motor cars have the advantage of being able to obtain a large driving force regardless of the adhesive force between the wheels and the rails, and requiring no moving parts in the drive system. Expectations are high.

Various types of linear motor cars have been proposed, and one of them is IJ = indaxis a.
A secondary conductor will be provided on the primary mV umbrella of the /7-tar (hereinafter referred to as LIM) and on the running path 111. 5Kt
There is also the so-called Rinjo Ikyu method.

This first-over-first-order LIM is illustrated in Figures 1 and 2, for example.
As shown in the figure, &t4 is roughly configured.In these figures, l is the primary core, 2 is the primary coil, 3 is the secondary conductor, 4
is the gap.

The primary iron core l around which the primary coil 2 is wound is located on the floor IJ1 of the vehicle.
1 F ms, etc., and is arranged at a gap 4 of a predetermined size with respect to a secondary conductor 3 installed along the travel direction at a predetermined portion of the running path.

Then, by supplying a predetermined alternating current to the 71st coil 2 to excite the primary core 1, the interaction between the alternating current magnetic flux generated from K and the secondary 4tlL induced in the secondary conductor 3, Since a driving force is generated in the direction of the arrow, it is possible to apply propulsive force or braking force to the vehicle, thereby accelerating or decelerating the vehicle.

By the way, in such a LIM, in order to maintain good optical characteristics and easily obtain the necessary driving force,
In order to
It is desirable that both 44 be made of a material with large diameters.

However, at present, it is not possible to obtain a single material that has electrical conductivity comparable to steel or aluminum, and magnetic permeability comparable to iron. If a secondary conductor, a so-called early-secondary conductor, is used, it cannot be expected that both conductivity and magnetic permeability are sufficiently large, and the performance as a LIM cannot be fully demonstrated.

Therefore, as such secondary conductors, composite secondary conductors have traditionally been used, which are made by laminating materials with excellent magnetic permeability, such as aluminum, and materials with high magnetic permeability, such as iron. This ensures that the required performance can be obtained.

However, this composite secondary conductor uses two or more types of materials, and requires a special joining method to combine their advantages, such as a pressure welding method that utilizes the explosive power of gunpowder. The cost is significantly higher than that of conductors.

Therefore, the conventional LIM-based one-type linear motor*a has a disadvantage in that the cost of installing the secondary conductor becomes extremely high.

The object of the present invention is to eliminate the disadvantages i of the prior art,
Note for air motor cars with on-board primary system using IM,
It is an object of the present invention to provide a linear motor device for a vehicle that can sufficiently reduce the cost of installing a secondary conductor without compromising @4.

In order to achieve this purpose, the present invention requires the composite secondary conductor of the on-vehicle primary type LIM to provide driving force such as acceleration force and power to the vehicle within the vehicle traveling section. The point is that it is installed only in sections.

Hereinafter, the embodiment IIa of the linear motor device for a vehicle according to the present invention will be described.
An example will be explained with reference to the drawings.

FIG. 3 shows an embodiment of the present invention, where 5 represents a vehicle with LIM as a drive line, and 6 represents road a.

And this -Route 6 is established between two stations A and B,
It is assumed that the vehicle 5 departs from station A and is operated to station B. In addition, 3 is a composite secondary conductor. In the present invention, as described in 5 above, the composite secondary conductor 3 is installed only in the necessary section of the section where the vehicle 5 is operated. In the embodiment shown in Fig. 3, the coupled double conductor 3 is installed only in a predetermined section C from station A' to station BK, and in a predetermined section DK in front of station B, and in the section E between them. Do not install a secondary conductor.

Now, assume that vehicle 5 is stopped at station AK and is about to leave for station BK'.

' Then, since the composite secondary conductor 3 is installed in the predetermined section CK including this station 'A', the LIM installed in the vehicle 8 can exhibit sufficient performance due to the composite tertiary conductor 3. However, within this section C, the necessary acceleration force is applied to propel the vehicle 5, and it is possible to drive the vehicle 5 to a predetermined speed. As a result, it is possible to start the vehicle from station A with sufficient acceleration according to the required IK, and drive it within section C to reach the required RK.゛Next, the car 1115, which has wandered moderately in section C, enters section E. However, no secondary conductor is installed in this section B. #! Therefore, when the vehicle 6 enters this section E, the vehicle 5 in question cannot accelerate, but when such a vehicle is taken away, it accelerates from a stopped state, reaches a predetermined speed, and then accelerates. Since it is a normal operation method to keep the vehicle running by coasting, there is no problem in vehicle operation due to the lack of a secondary conductor in this section E, and vehicle 5 does not move in section E. It is possible to operate the vehicle so that it travels at a nearly constant speed while decelerating slightly.

Eventually, after passing through Section E and approaching Station B, where you should stop, you will see a composite secondary conductor 3.
Since the LIM of vehicle 5 is installed in this section,
It is possible to exert sufficient performance of K, and it is possible to apply negative propulsive force to the vehicle 5 to perform braking, and the station BK
It is possible to easily carry out the driving operations necessary to safely stop the vehicle 5.

Therefore, according to this embodiment, in the section gK where the vehicle 5 can travel by coasting, it is not necessary to arrange not only the composite secondary conductor 3 but also any other secondary conductor. Since there are sections where the amount of conductor used is small and there is no need to install a secondary conductor at all, the cost associated with installing the secondary conductor can be significantly reduced.
In vehicles using IM, in order to keep the LIMf) characteristics constant, the gap 4 between the primary core l and the secondary conductor 30 is
(See Figures 1 and 2) must be kept constant while the vehicle S is traveling, and therefore a considerable amount of water is required to install the secondary conductor for the S fault 6. The cost required for installing the secondary conductor is quite large. However, before #! In the embodiment, since no secondary conductor is required to be installed in section E, which occupies a large portion of the operating section of the vehicle 5, a large cost reduction is possible.

Next, Fig. 4 and Fig. 5 are examples in which there is an uphill slope section F and a downhill slope section G in the operation section of the rolling stock, and in both cases, the composite secondary conductor is included in the slope section F1G. 3 is installed, and the necessary propulsive force and splitting force are obtained by a single 5 LINK, and its operation and effect are the same as in the case of Fig. 3, and it is not accompanied by a large storage tube. Vehicle 6 in both the uphill slope section F and the downhill slope section G.
It is possible to maintain the required speed and drive safely.

By the way, in five or more embodiments, within the operating section of the vehicle 5 equipped with LIM, the vehicle 6 is provided with a propulsive force or 1llJ11.
+ Sections that require force, for example sections C and D.

The composite secondary conductor 3 is installed only in F and G, and no secondary conductor of any kind is installed in other sections, for example, section E. Therefore, the operation of the vehicle 5 is However, in an embodiment of the present invention, a composite secondary conductor is installed in all sections where a composite secondary conductor is not installed, for example, in section E, a secondary conductor made of a single material is made possible. The secondary conductor, the so-called 4-secondary conductor, may be changed to #.

According to this embodiment, [
Due to the presence of the secondary conductor, the cost reduction effect will be less than in the embodiment described in section m, but it will be possible to propel the vehicle and brake with LIME anywhere within the operating section, which will improve vehicle operation. You can increase your degree of freedom. In addition,
In this case, the section where the single secondary conductor should be provided is not all the sections other than the intermittent sections of the composite secondary conductor, but it may be provided at -11 of the section.

As mentioned in 11@ above, according to the present invention 1jIK, the composite secondary conductor is provided only in the part where the driving force by the LIM is required for the light component, so the drawbacks of the conventional technology are eliminated and the driving force of the vehicle is improved. It is possible to provide an air cage device around a vehicle that can greatly reduce costs without causing any negative impact.
