JPH09182205A - New model pantagraph - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a new model pantagraph which is small and low, little in abrasion of a stringing, durable, and hardly lets spark throw and withstands high-speed revolution, by enabling a rim to move freely along the axis, using a rim for the section in contact with a stringing, and using rollers in three stages for a bearing. SOLUTION: A shaft 3 is supported through a shaft support 4 by a vehicle body 5, and rollers are piled in three stages for a bearing so that a rim can move freely along the shaft, and it is brought into contact with a trolley wire 2. Hereby, a pantagraph which is small and low, little in abrasion of a stringing, durable, and hardly lets spark fly and withstands high-speed revolution can be obtained. Moreover, noise decreases, and management becomes easy.

Description

Detailed Description of the Invention

[0001]

[Industrial application] Rail vehicles, trolley buses, wired communications, and high-speed driving objects.

[0002]

2. Description of the Related Art Conventional pantographs have a large height and are large in size, and the overhead wires are often worn and not durable, and sparks fly, making them unsuitable for high-speed operation.

[0003]

[Problems to be solved by the invention] High-speed driving without fear
Reduce electrical system failures, reduce size, reduce noise, and facilitate management.

[0004]

[Means for Solving the Problems] A rim is used in a portion that comes into contact with an overhead wire, and rollers are stacked in three stages on a bearing so that the rim can freely move along an axis.

[0005]

[Operation] Fast operation without anxiety, reduction of electric system failures, miniaturization, noise reduction, and easy management.

[0006]

EXAMPLE As shown in the drawings.

[0007]

EFFECTS OF THE INVENTION High-speed operation without anxiety, reduction of electric system failures, downsizing, noise reduction, and easy management.

Claims (1)

[Claims] 1. A pantograph that is small in size, low in height, less likely to wear overhead wires, durable, resistant to sparks, and capable of withstanding high-speed operation.
