【発明の詳細な説明】
本発明は電気移動体用集電子（以下集電子という）の製
造方法に関するものであり、耐摩耗性に優れた集電子を
得んとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a current collector for an electric mobile body (hereinafter referred to as a current collector), and is intended to obtain a current collector with excellent wear resistance.
従来集電子は導電性を必要とするためＣｕ系合金、Ｆｅ
系合金又はＣ系合金等の金属により長方形又は正方形の
板状体に成形されているものである。Conventional current collectors require conductivity, so Cu-based alloys, Fe
It is formed into a rectangular or square plate-like body from a metal such as a C-based alloy or a C-based alloy.
この集電子はパンタグラフ等の先端にヒンジを介して取
付け、トロリ線がカテナリ状に湾曲していても、その接
触面積が広くなるようにしている。This current collector is attached to the tip of a pantograph or the like via a hinge, so that even if the contact wire is bent into a catenary shape, its contact area is wide.
しかし、このようにしても集電子は電気移動体の走行に
伴って、特に起動時にはその走行方向側の側辺部がトロ
リ線と強く接触しているものである。However, even in this case, the side portion of the current collector on the side in the running direction is in strong contact with the contact wire as the electric movable body moves, especially when starting up.
従って集電子は局部摩耗を生じ、その摩耗量が太き（な
ると必然的に集電子の溝は深くなりトロリ線は横スライ
ド作用をしなくなり、その溝は円弧状溝からＶ型状溝に
変形し、削り取られるようになり、その寿命は早くなり
使用にたえないものとなる。Therefore, local wear occurs on the collector, and the amount of wear increases (as a result, the groove in the collector inevitably becomes deeper, the contact wire no longer slides horizontally, and the groove changes from an arc-shaped groove to a V-shaped groove). However, it begins to wear away, shortening its lifespan and making it unusable.
なお前記の如き金属に代えて耐摩耗性の優れた材料もあ
るが、導電性に劣るため使用し難い現状であった。Although there are materials that have excellent wear resistance in place of the metals mentioned above, they are currently difficult to use because of their poor electrical conductivity.
本発明はかかる現状に鑑み鋭意研究を行った結果、耐摩
耗性並びに導電性が共に優れた集電子の製造方法を見出
したものである。即ち本発明は銅、鉄等の導電性材料か
らなる電気移動体用集電子本体の少なくとも電気移動体
の走行方向側の側辺部に耐摩耗性金属を溶射して溶射層
を形成するものである。The present invention has been made as a result of intensive research in view of the current situation, and has resulted in the discovery of a method for manufacturing a current collector that is excellent in both wear resistance and conductivity. That is, in the present invention, a wear-resistant metal is thermally sprayed to form a sprayed layer on at least the side portion of a current collector body for an electric vehicle made of a conductive material such as copper or iron in the traveling direction of the electric vehicle. be.
本発明において特に溶射層を形成する理由は、金属を溶
射することによって集電子本体によく密着し、熱又は振
動等をうけるもその接触面から溶射金属が剥離すること
がないためである。The reason why a sprayed layer is formed in particular in the present invention is that by spraying the metal, the metal adheres well to the current collector body, and the sprayed metal will not peel off from the contact surface even if subjected to heat or vibration.
なお集電子本体に耐摩耗性金属を複合せしめた場合ては
、熱、撮動等により耐摩耗性金属が剥離するおそれがあ
る。Note that if the collector body is made of a composite of wear-resistant metal, there is a risk that the wear-resistant metal may peel off due to heat, photography, etc.
本発明において溶射層を形成する金属としては、その集
電子本体を講成する金属によって選定されるものであり
、例えば集電子本体がＣｕ合金の場合にはＳＵＳ、モリ
ブデンを溶射するものであり、Ｆｅ合金の場合にはモリ
ブデン、ニッケルクロム大、ＮｉＴｉ合金、を溶射する
ものである。In the present invention, the metal forming the sprayed layer is selected depending on the metal forming the current collector body. For example, if the current collector body is a Cu alloy, SUS or molybdenum is sprayed. In the case of Fe alloys, molybdenum, nickel chromium, and NiTi alloys are thermally sprayed.
又（容射層の位置は集電子本体においてトロリと接触し
て摩耗し易い場所即ちその周辺特にトロリの走行方向側
の側辺に設ければよい。しかし溶射層を必要以上に拡大
すると逆に集電子の導電性が低下するため、溶射層は最
少限に設ける必要がある。(The sprayed layer may be placed in the collector body at a place where it comes into contact with the trolley and is likely to be worn out, that is, around the area, especially on the side in the running direction of the trolley. However, if the sprayed layer is expanded more than necessary, it may cause damage. Since the electrical conductivity of the current collector decreases, it is necessary to provide the sprayed layer to a minimum.
又溶射層を形成せしめるには、溶射せんとする位置の集
電子本体をけずり取り、この部分に溶射金属を集電子本
体と同じ高さに溶射すればよい。Further, in order to form a sprayed layer, the collector body may be scraped off at the location where the spray is to be sprayed, and the sprayed metal may be sprayed onto this portion at the same height as the collector body.
次に本発明の一例を図面により説明する。第１図及び第
２図に示す如く銅合金よりなる正方形の集電子本体Ｉの
両側辺をシナずりとつ、ここ：でＳＵＳを溶射して溶射
層２を設げて集電子を形成する。Next, an example of the present invention will be explained with reference to the drawings. As shown in FIGS. 1 and 2, both sides of a square current collector body I made of a copper alloy are cut out, and SUS is thermally sprayed here to provide a thermally sprayed layer 2 to form a current collector.
このように、＠射層２を対向１−た両側辺に設ければ後
退する場合にも対処し得る。尚、矢印は走行方向を示す
。In this way, by providing the @ radiation layer 2 on both opposing sides, it is possible to cope with the case of retreat. Note that the arrow indicates the direction of travel.

用年数を格段と長くし得る等の作用効果を奏する。Therefore, the present invention provides a thermal spray layer by spraying a wear-resistant metal on at least the side portion of the current collector body for an electric movable body made of a conductive raw material in the running direction of the electric movable body. Even if the side portion of the current collector comes into strong contact with the contact wire when the body is started, there is little wear on that portion, and therefore the service life can be significantly extended compared to conventional products.
