Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a current collector for a high-speed rail vehicle propelled by a linear motor or the like.

The present invention relates to a current collector for supplying power from the ground to an on-board primary winding of a linear motor, cooling equipment for a superconducting magnet, an active damping device for preventing vibration of a car body, and other on-board equipment.

Friction current collection in conventional tracked vehicles has a speed of 250
If the speed exceeds ~300 Km/h, the current collector will be seriously damaged and current collection will become very difficult. Therefore, in addition to the frictional current collection method, the present invention switches to the induction current collection method in the speed range where frictional current collection is difficult (250 km/h or more) to prevent wear and tear on the frictional current collector and enable efficient current collection. That is.

First, the configuration of the present invention will be explained based on an embodiment. As shown in FIG.
The power supply sheet 1 is attached to the front and rear sides of the vehicle, and is in sliding contact with the power supply sheet 1 installed on the side track wall 31 to supply power from the ground power source to the onboard equipment. As shown in FIG. 2, each current collector 30 is attached to the vehicle body 4 via a suitable cushioning material 8, and extends vertically through a fixing member 21 inside the cover 3 made of an insulating material. It is provided with a pair of front and rear induction current collectors each consisting of a large number of strands 12. A bracket 18 is fixed inside each fixed member 21, and a lever 5 is supported on this with a support shaft 6. A friction current collector 16 is attached to the outer end (front and rear ends) of the bracket 18, and an oil supply pump 28 is attached to the inner end of the bracket 18. Each is combined.

The frictional current collector 16 is connected to the outer end side of the front and rear yokes 14 and the permanent magnet 15 superimposed between them, and the strength member 2 made of a non-magnetic material is connected to the inner end side and is connected to the lever 5. The frictional current collector 16 configured in this manner is placed laterally with respect to the frame portion 10 made of an insulating material disposed inside the cover 3.
In other words, it is guided and supported so as to be slidable in a direction perpendicular to the surface of the power supply sheet 1 .

The refueling pump 28 includes a cylinder 23 disposed in the frame 10 described above, and a lever 5 fitted into the cylinder 23.
The lubricant stored inside the cylinder 23 is ejected from the outlet 11 toward the power supply sheet 1 by the piston 7 . A check valve 29 consisting of a ball 24 and a spring 25 is attached to the outlet 11 as shown in FIG.

Note that the outer surface of the frame portion 10, that is, the portion facing the power supply sheet 1, is coated with a friction material 9 having wear resistance, low friction, and nonmagnetism.

As shown in FIG. 3, a conductive plate 19 is superimposed on the upper surface of the cover 3, and an insulating plate 20 is superposed on the lower surface thereof, and these are fixed by bolts 13 passing between the wire groups 12. Then, a pair of front and rear wire groups 12
The upper ends are electrically connected to each other by the conductive plate 19, and the lower ends of each wire group 12 are configured as terminals and connected to electrical equipment on the vehicle.

As shown in FIG. 2, a winding 17 for generating a moving magnetic field is installed on the wall surface of the side track wall, and an insulating material is applied to the outside of the winding 17 to fix the power supply sheet 1. It can also serve as a field for the motor.

Next, to explain the operation of the present invention, when the vehicle is running at low speed, the frictional current collector 16 is
Collect current by contacting. The permanent magnet 15 coupled to the frictional current collector 16 forms magnetic poles with different polarities at the ends of the front and rear yokes 14 facing the power supply sheet 1, and as the vehicle runs, copper and aluminum An eddy current is generated in the power supply sheet 1 consisting of, etc. Then, when the traveling speed reaches the limit range of frictional current collection, the current collector 16 receives a repulsive force against the power supply sheet 1 due to interaction with the magnetic field based on the eddy current. This result collection electronic 1
6 slides against the frame 10 and separates from the power supply sheet 1. Then, the lever 5 is rotated about the support shaft 6, the piston 7 is pushed outward, and the lubricant in the cylinder 23 is supplied to the power supply sheet 1 from the outlet 11. This serves as lubrication when the friction material 9 comes into contact with the power supply sheet 1 due to vibrations of the vehicle body.

When a vehicle runs at high speed, the wires 12 arranged in the vertical direction cross the magnetic field lines perpendicular to the track surface (horizontal direction) generated by the windings 17 of the track. A current flows from the lower end through the conductive plate 19 to the lower end of the other wire 12, and is supplied to the electrical equipment on the vehicle.

Since the present invention is configured as described above, in the low speed range of the vehicle, current is collected from the power supply sheet on the track side by friction current collector, and in the high speed range, the friction current collection is automatically interrupted, and the winding on the track side Therefore, it is possible to perform inductive current collection from the vehicle, thereby avoiding wear and tear on the frictional current collector during high-speed running. Additionally, the frictional current collector has the effect of preventing side-to-side vibration of the vehicle body in low-speed driving ranges. Furthermore, during high-speed running, since lubricant is supplied to the track side, wear due to contact between the friction material 9 covering the induction coil and the track can be prevented.
