Abstract

PURPOSE:To minimize abrasion of collector shoe and to prevent the collector shoe from coming off a stringing by supporting a current collector on the frame of truck in a pendulum vehicle without complicating the body structure thereby suppressing relative motion of the collector shoe with respect to the stringing as low as possible. CONSTITUTION:A truck frame 2 is coupled with a supporting frame 4 which is fixed through insulators 5 with a pantograph 6 at a position where the center of collector shoe 7 coincides with the center of rotation of the truck. Since a current collector is supported directly on the truck frame 2 while matching the center of the collector shoe 7 with the center of rotation of the truck without complicating the body structure, relative motion between the collector shoe 7 and the stringing can be suppressed, abrasion of the collector shoe 7 can thereby be suppressed resulting in prevention of the collector shoe 7 from coming off the stringing.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a current collector for a train that collects power from an overhead line, and more particularly to a current collector for a pendulum train.

[0002]

2. Description of the Related Art A conventional pendulum train current collector is, for example, a Co
nvegno internaziopale transportiferroviari Torino-
As shown in 28-29 settembre 1969, the support frame of the current collector was connected to the center of the carriage.

[0003]

In the above-mentioned prior art, since the support frame of the current collector penetrates the vehicle body at the center position of the bogie, the cross beam of the vehicle body underframe cannot be constructed, and therefore the vehicle body strength is increased. In order to secure it, I had no choice but to use a complicated body structure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a current collecting device which can construct a pillow beam for a vehicle body frame as in the prior art and can make the rotation center of the carriage and the current collecting boat coincide with each other. By the way, if the rotation centers of the carriage and the current collecting boat do not coincide with each other, relative movement occurs between the overhead line and the current collecting boat, and there is a problem that the current collecting boat wears faster. There is also the danger that the overhead line will come off the current collector boat.

[0005]

In order to achieve the above object, a pantograph support frame is connected to an end of a bogie frame so that the pantograph support frame penetrates the vehicle body at a position avoiding a pillow beam of the vehicle body underframe. I chose Also, the pantograph is fixed to the support frame at an appropriate position so that the center of rotation of the carriage coincides with the center of rotation of the current collecting boat. As a result, the relative movement between the overhead line and the current collecting boat can be minimized.

[0006]

In a general vehicle, a pillow beam of the vehicle body underframe exists above the center of rotation of the bogie. Therefore, the pantograph support frame cannot penetrate the vehicle body at this position. Therefore, the support frame penetrates the vehicle body at a position slightly away from the center of rotation of the bogie and is joined to the bogie frame. A pantograph can be mounted on the upper part of the support frame, and the pantograph can be fixed to the support frame at a position where the center of the collector boat of the pantograph coincides with the rotation center of the carriage.

Between the current collector and the vehicle body, a relative movement due to the pendulum action of the vehicle body and a relative movement due to the rotation of the carriage are performed. The flexible cable passed between the current collector and the insulator on the roof of the vehicle body is allowed to allow these relative movements.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. In FIG. 2, reference numeral 1 is a vehicle body, and four support frames are provided on both sides of the vehicle body, and a support frame space 1a is secured from the top to the bottom so that the support frame space 1a can be avoided even if there is relative motion with the vehicle. .. Reference numeral 2 indicates a bogie frame of the bogie. The support frame 4 is rotatably connected to the bogie frame 2 by a joint 3. In FIG. 1, the support frame 4 is joined by a joint 3 at a slightly eccentric position, not at the center of the bogie frame 2. The center is the center of the bogie frame 2 in the traveling direction. This is to allow the support frame 4 to penetrate the vehicle body 1 even if the bolster of the underframe of the vehicle body 1 exists above the center position of the vehicle frame 2. The upper portion of the support frame 4 is bent into an L shape so that the pantograph 6 can be supported via the insulator 5. A collector boat 7 is provided above the pantograph 6 so that electricity can be collected from the overhead line 8. The connection between the support frame 4 and the bogie frame 2 is freely rotatable. Therefore, the support frame 4 is supported by the roof of the vehicle body 1 via the support rods 9 so as not to fall back and forth. The vehicle body 1 and the support frame 4 are
Since the pendulum motion of the vehicle body and the relative motion associated with the rotary motion of the carriage are performed, the joint between the support rod 9 and the vehicle body 1 or the joint between the support rod 9 and the support frame 4 is freely rotatable. 11
Is an insulator provided on the roof of the vehicle body 1. When the collected electricity is guided to the vehicle body, the pantograph 6 and the insulator 11 also make a relative movement, so that the flexible cable 10 that allows this relative movement electrically connects the pantograph 6 and the insulator 11. The mechanism of the pendulum between the bogie frame 2 and the vehicle body 1 is known. The alternate long and short dash line indicates the vehicle limit.

In the pendulum vehicle, it is a technically important point that the current collecting boat 7 can collect current even when the pendulum is moving, without coming off from the overhead line 8. As one of the methods, there is a method in which the current collector is directly supported by the bogie frame 2.
According to this method, the current collector 7 does not disengage from the overhead line 8 because the current collector is not displaced even if the vehicle body 1 swings. The conventional problem with this method is that the pantograph support frame 4 is located at the center of the bogie, so that the pillow beams of the carbody underframe cannot be arranged, and in order to ensure strength, the car body structure must be complicatedly arranged. There wasn't. This problem is solved by changing the position where the support frame 4 penetrates the vehicle body. That is, it is solved by connecting the support frame 4 to the end of the bogie frame 2. The upper portion of the support frame 4 was bent into an L shape, and the pantograph was attached at an appropriate position to arrange the current collecting boat 7 on an extension of the rotation center of the carriage.
As a result, when considered in a horizontal plane, the center of rotation of the dolly and the center of the current collecting boat 7 coincide with each other, so that even if the dolly rotates, the current collecting boat 7 will not move and will not be displaced. ,
The wear of the collector boat 7 can be minimized and the risk of the collector boat 7 coming off the overhead line 8 can be avoided.

In FIG. 3, a space 1a for vertically penetrating the support frame 4 is provided near the entrance 20 on the side surface. 25 and 26 are toilets and washrooms. In this way, the support frame 4 is provided at the end of the bogie frame 2 on the side of the end 22 of the vehicle body 1 in the front-rear direction. According to this, compared with the case where the support frame 4 is connected to the opposite end, the vicinity of the entrance 20 can be made as large as possible.
Further, in the case where the toilet 25 and the washroom 26 are not provided, it is possible to prevent the space 1a from being provided in the middle of the passenger room 23.

According to the present invention, the center of rotation of the carriage and the center of the collector boat can be made to coincide with each other without complicating the vehicle body structure.
