Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad vehicle device such as a railroad car, a tram, a monorail or the like (hereinafter referred to as a contact-type railcar vehicle) which is constructed such that the wheels are self-propelled in contact with the rail. In particular, the present invention relates to a contact-type track vehicle device capable of improving the stability of a vehicle during high-speed traveling and cornering and the traveling performance on a steep slope.

[0002]

2. Description of the Related Art It is well known that the problem of running stability in a contact type track vehicle is closely related to the weight and track width of the track vehicle and the curvature of the track in a non-linear region such as a curve. It is also well known that the limit of the high-speed traveling speed due to the wheel idling during high-speed traveling exceeding 300 km / hour or more, for example.

Further, in the conventional contact type track vehicle, in order to secure the inclination stability of the vehicle in the non-linear region such as a curve, it is necessary to take a large curvature of the track in the non-linear region. Therefore, there is a problem that the track laying site becomes vast, and it is not suitable for high-speed railways especially in urban areas. Since the wheels run idle and cannot move up and down, special locomotives for moving up and down must be connected and a switchback system must be adopted, which causes many problems such as enormous equipment cost.

The present invention was devised in view of the above situation, and an object thereof is to prevent a wheel from idling when a contact type track vehicle exceeds, for example, 300 km / hour or more and to achieve high speed. Contact-type high-speed track vehicle device that enables stable running and is able to run stably even in a non-linear area such as a curve with a small curvature, and can also climb up and down steep slopes without separately installing large-scale equipment. Is to provide.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is premised on a tracked vehicle apparatus configured to allow a vehicle having wheels to be self-propelled along a track. The wheels are provided with magnetism that is attracted to the track along the circumferential direction of the wheels.

In the present invention, the magnetism is imparted by a permanent magnet made of a compound of neodymium, iron and boron or an electromagnet.

When magnetism is imparted by an electromagnet, the magnetism is imparted when the traveling speed of the vehicle exceeds a certain speed, or the magnetic force thereof is variably controlled according to the traveling speed. This is to prevent the acceleration at the time of shifting from the stop of the vehicle to the traveling to be attenuated by the magnetic force.

In the present invention, the magnetic body for applying the magnetic force may be a solid buried in a wheel or a rubber tire mixed with magnetic powder.

Further, in the present invention, when the track is laid on an inclined surface or a non-linear area, an auxiliary track is laid along the track laid on the inclined surface or the non-linear area, The vehicle can be configured so as to improve running stability on the inclined surface and the non-linear region by disposing a tracked body that is attracted to this auxiliary track.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below based on an embodiment shown in the accompanying drawings.

As shown in FIGS. 1 and 2, a rail vehicle 1 according to this embodiment has a vehicle main body 2 having a passenger compartment or a driver's seat formed therein, and is rotatably supported on the lower surface of the vehicle main body 2. The magnetized wheel 3, the drive device 4 for rotating the wheel 3, and the auxiliary rail 6 laid between the rails 5 and 5 having the same width as the wheel 3. It is configured to have an endless track 7 to be attracted and width regulating rollers 8 arranged on both sides of the rails 5 and 5.

The vehicle body 2 is constructed in the same manner as the body of a known self-propelled track vehicle, and therefore its detailed description is omitted here.

The wheel 3 is, for example, made of a metal like a known railroad wheel or a known rubber tire. As shown in FIG. 3 and FIG. The permanent magnets 6 to be attracted are embedded and formed at predetermined intervals. Of course, this permanent magnet 6 can also be arranged over the entire circumference of the wheel 3.

The permanent magnet 6 is preferably a permanent magnet formed of a known compound of neodymium, iron and boron, for example, but the present invention is not necessarily limited to this, and samarium is used. It is also possible to use a permanent magnet made of a cobalt compound or another known strong permanent magnet.

When the wheel 3 is made of a rubber tire, the permanent magnet 6 having such a composition has a substantially sectional shape as shown in FIG. 4 in order to secure a large contact area with the rails 5 and 5. It is desirable to form it in a concave shape. Of course, when the wheel 3 is formed of a rubber tire, the rubber tire itself can be formed as a magnetic body by mixing magnetic powder during molding.

The permanent magnet 6 is, for example, 300 in a vehicle.
Adsorption magnetic force is applied to prevent idling of the wheels 3 that occurs when traveling at a high speed of Km or more, and / or attraction magnetic force is applied to prevent the vehicle body 1 from tipping over in the curved areas of the rails 5, 5. , Or / and an attraction magnetic force that prevents the wheel 3 from idling on the steep slope is applied,
These attracting magnetic forces affect the weight of the rail vehicle 1 and the rails 5, 5
Width, the curvature of the rails 5 and 5 in the curve, the inclination angle of the inclined surface, and the like, which are relatively determined based on experimental values and the like.

However, the attraction force is not limited to the case where it is provided by the permanent magnet 6, and in the present invention, although not shown, it can be provided by an electromagnet.

When the attracting magnetic force is applied by an electromagnet, it is desirable that the attracting magnetic force is applied when the traveling speed of the track vehicle becomes a certain speed or more. Correspondingly, it is desirable that the attraction force be variably controlled.

This is because when the acceleration when the tracked vehicle shifts from running to running is such that permanent magnets always generate a magnetic force, the torque required for the initial rotation of the wheels depends on the magnetic attraction force. This is to effectively prevent the power loss from becoming much larger than that of a normal track vehicle without magnetic force.

Further, since the adsorption magnetic force can be variably controlled according to the traveling speed, the power consumption required for the electromagnet can be controlled in the case of the medium speed traveling, the high speed traveling and the super high speed traveling. Can be improved.

Since the construction of the electromagnet and the magnetic force control means are the same as those known in the art, a detailed description thereof will be omitted here.

The endless track 7 is arranged in front of and behind the lower surface of the vehicle body 2, and is constructed so as to sandwich and adsorb an auxiliary rail 6 laid between the rails 5 and 5.
It is composed of a magnetic belt 10 suspended between rollers 9.

Therefore, on a steep slope, the magnetic belt 10 is
Is rotated like a caterpillar of a bulldozer via a drive unit composed of a motor and a speed reducer (not shown), so that a special locomotive for lifting and lowering is not connected or a switchback system is adopted, and easily and Stable track vehicle 1
You can raise and lower by yourself even on steep slopes.

In this embodiment, since the magnetic belt 10 of the endless track 7 is made of a magnetic material and a magnetic force is applied to the wheels 3, at least 3 parts of the vehicle body 1 are provided.
The magnetic force of the endless track 7 is set to be so strong as compared with the case where magnetism is given only to the endless track 7 as described above, since it can be dispersed and adsorbed by the magnetic force of more than a point, and the stability and safety are further improved. There is no need, and the effect that high speed running on a steep slope is possible is obtained.

The width regulating rollers 8 are rotatably arranged on both sides of the lower surface of the vehicle body 1 so as to be rotatable, and are arranged so as to come into contact with the insides of the rails 5 and 5 in a normal state. It is configured to ensure running stability. Of course, the width regulating roller 8 may be magnetized.

Since the rail vehicle 1 according to this embodiment is configured as described above, for example, the rail vehicle 1 has 300 rails.
It is possible to reliably prevent idling of the wheels 3 that occurs when traveling at a high speed of Km or more, and it becomes possible to perform ultra-high-speed traveling, which was impossible with the conventional contact-type track vehicle. It is possible to ensure running stability in the vehicle, and to reliably prevent the vehicle body 1 from tipping over in the curved areas of the rails 5 and 5. In addition, it is possible to reliably prevent the wheel 3 from idling on a steep slope. A number of excellent effects can be obtained, such as being able to move up and down a steep slope without installing special equipment.

In the above embodiments, the case where the present invention is applied to a railroad car, a tram car, or the like is described as an example. However, the present invention is not limited to this. Of course, it can also be applied to a monorail, which is a type of contact track vehicle.

[0028]

Since the track vehicle device according to the present invention is constructed as described above, in the contact track vehicle, for example, the wheel is prevented from idling when the speed exceeds 300 km / h and the high speed stability is achieved. It has a number of excellent effects, such as enabling traveling, stable traveling even in a non-linear area such as a curve with a small curvature, and being able to ascend and descend even on steep slopes without separately installing large-scale equipment. Play.
