Abstract

Smykadlo podle vynálezu je určeno pro pantografové sběrače proudu kolejových vozidel závislé trakce a dovoluje všestranný výkyv smykadla, přičemž zároveň tlumí podélné i svislé nárazy na smykadlo od trolejového vedení. Smykadlo je k horní části pantografu připevněno pomocí spojovací tyče, která tvoří zároveň i hřídel horního kloubu pantografu, jakož í pomocí osmi tlačných pružin umístěných mezi patky horních i spodních držáků, přičemž podélné osy těchto pružin svírají se svislou osou spojovací tyče úhel v rozmezí 45° až 70°.The slide according to the invention is intended for pantograph current collectors of dependent traction rolling stock and allows versatile swing of the slide, while at the same time absorbing longitudinal and vertical impacts on the slide from the overhead line. The slide is attached to the upper part of the pantograph by means of a connecting rod, which also forms the shaft of the upper joint of the pantograph, as well as by means of eight compression springs placed between the feet of the upper and lower holders, the longitudinal axes of these springs forming an angle of 45° to 70° with the vertical axis of the connecting rod.

Description

Vynález se týká dvoulištového smykadla s pružným upevněním k pantografu sběrače proudu, které je vhodné pro kolejová vozidla.BACKGROUND OF THE INVENTION The present invention relates to a double-skid slide with flexible mounting to a pantograph of a current collector suitable for rail vehicles.

Doposud jsou dvoulištová smykadla odpružena pouze ve svislém směru, což je nedostačující, nebot jsou chráněna proti nárazům které dostávají od trolejového vedení ve směru své podélné osy a to zejména, jsou-li použita u pantografových sběračů proudu na vozidlech městské hromadné dopravy. Těmito nárazy trpí jak trolejová vedení, tak i smykadla, což se projevuje zvýšením nákladů na jejich údržbu.Until now, double slats are suspended only in the vertical direction, which is inadequate because they are protected against impacts they receive from the overhead contact line in the direction of their longitudinal axis, especially when used with pantographs on public transport vehicles. Both the overhead contact lines and the slideers suffer from these impacts, which results in increased maintenance costs.

Výše uvedené nedostatky jsou odstraněny dvoulištovým smýkadlem s pružným upevněním k pantografu sběrače proudu podle vynálezu, jehož podstatou je, že mezi patky dvou horních držáků opatřených dvěma sběrnými lištami a patky dvou spodních držáků jsou umístěny a upevněny tlačné pružiny tak, že podélná osa každé tlačné pružiny svírá se svislou osou spojovací tyče, na jejíž obě strany jsou spodní držáky nasazeny, úhel v rozmezí 45° až 70°. Tlačné pružiny jsou soudkového tvaru.The above drawbacks are overcome by the double-sided plunger with flexible attachment to the pantograph of the current collector, which consists in that between the feet of the two upper holders provided with two header rails and the feet of the two lower holders are located and fixed compression springs so that it forms an angle in the range of 45 ° to 70 ° with the vertical axis of the tie-rod on both sides of which the lower brackets are fitted. The compression springs are barrel-shaped.

Uspořádání dvoulištového smykadla s pružným upevněním k pantografu sběrače proudu dovoluje všestranný výkyv smykadla a zároveň tlumí podélné i svislé nárazy na smýkadlo od trolejového vedení, čímž se značně prodlužuje životnost jak smykadla, tak i trolejového vedení.The arrangement of the bipolar slide with flexible attachment to the pantograph of the current collector allows for a versatile swing of the slide and at the same time dampens longitudinal and vertical impacts on the slide from the overhead contact line, greatly extending the service life of both the slide and overhead contact line.

Na připojeném výkresu je příklad provedení dvoulištového smykadla s pružným upevněním k pantografu sběrače proudu podle vynálezu, ve kterém znázorňuje: obr. 1 - schematické znázornění pantografového sběrače, proudu při pohledu z boku, obr. 2 - detailní pohled z boku na připojení dvoulištového smykadla s pružným upevněním k pantografu sběrače proudu, obr. 3 - detailní pohled ze shora na připojení dvoulištového smýkadla s pružným upevněním k pantografu sběrače proudu.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic illustration of a pantograph, current viewed from the side; FIG. 2 is a detailed side view of a double-slide contact with Fig. 3 - Detail view from above of a double-sided slide with flexible attachment to the pantograph of the current collector.

Pantografový sběrač proudu se skládá z pantografu se základnou 3i a z dvoulistového smýkadla s pružným upevněním k pantografu.The pantograph consists of a pantograph with a base 3i and a two-blade slide with a flexible attachment to the pantograph.

Pantograf je sestaven ze dvou bočních soustav ramen, z nichž každá obsahuje dvě stejná spodní ramena j_ a dvě stejná horní ramena 2_. Všechna čtyři ramena J_, 2_ jednéThe pantograph is composed of two side arms systems, each comprising two identical lower arms 1 and two identical upper arms 2. All four arms 12 of one

Claims

Double-sided ram with flexible attachment to the pantograph of the current collector, characterized in that between the feet of the two upper holders (9) with two header rails (11) and the feet of the two lower holders (8) mounted on both sides of the tie rod (10) are Compression springs (7) are disposed, the longitudinal axis of the arm assembly being articulated to each other in a diamond shape such that each lower arm (6) is connected to its base (3) via its lower end (4) and its middle end (5). to which the upper arm 24 is also connected at one end, the other end being connected to the upper joint 6. This upper joint 6 connects the two upper arms 2 and is the highest point of the arm system.

The bipolar slide with flexible attachment to the pantograph consists of two identical header strips 11, two upper brackets 9, two lower brackets 8, eight barrel-shaped compression springs 7, and a swivel bar 10. which contact the overhead contact line 12 near the center of its length.

Said parts are mutually arranged such that the skirting strips 11 are attached to the arms of the upper brackets 9 near their ends. The upper bracket 2 is formed by a bar-shaped connector, at the ends of which the rectangular-shaped arms are provided. two holes for fixing two compression springs «7.
