本発明は、重ね板ばね、すなわち、重ね合わせた２枚以
上のばね板により構成された重ね板ばねのさび止め方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing rust in a stacked leaf spring, that is, a stacked leaf spring constituted by two or more overlapping spring plates.
足米五退遣
このような構成を有している重ね板ばねは、ばね板同志
の間の擦過しゆう動によって生ずる摩擦力による減衰効
果を有するので、他の減衰手段を必要としないか、ある
いは、小容量の減衰手段の使用で済むという利点があり
、車両の懸架装置用として広く使用されていることは、
周知のとおりである。A stacked leaf spring having such a configuration has a damping effect due to the frictional force generated by the sliding movement between the spring plates, so other damping means are not required. Alternatively, it has the advantage of requiring the use of small-capacity damping means, and is widely used for vehicle suspension systems.
As is well known.
しかしながら、その反面、このような構成を有している
重ね板ばねは、その構造上、隣接するばね板の重なり合

よるすき間腐食が生じ、この結果、腐食疲労に基づくば
ね板の折損事故が発生する恐れがあるなどという問題点
を有している。However, on the other hand, due to its structure, a stacked leaf spring having such a configuration cannot avoid creating a narrow gap between the overlapping parts of adjacent spring plates, and therefore Crevice corrosion occurs due to moisture entering from the outside and electrolytic solutions (e.g. road antifreeze), which can lead to breakage of spring plates due to corrosion fatigue. have.

揮する高濃度亜鉛末塗料が提案されており、既に、車両
懸架装置用重ね板ばねに実施されて、一応の効果のある
ことが確認されている。Conventionally, in order to solve this problem, the surface of each spring plate in a stacked leaf spring is coated with a synthetic resin paint to prevent rust. It is difficult to sufficiently prevent crevice corrosion due to peeling of the paint film due to sliding motion.Recently, high-concentration zinc powder paints have been proposed, which exhibit an electrolytic protection effect even if the paint film peels off to some extent. This method has already been applied to stacked leaf springs for vehicle suspension systems, and it has been confirmed that it is somewhat effective.
しかしながら、亜鉛末塗料だけによっては、酸性及びア

の悪化や、高応力化による軽量化が進む現状から見て、
車両の保証期間の延長という社会要求に対しても、まだ
、不十分であるという問題点が残されている。However, when using zinc dust paint alone, zinc easily dissolves when used in acidic or alkaline environments, and its original rust-preventing effect is lost. Considering the current situation where the environment is deteriorating and weight reduction due to high stress is progressing,
In response to the social demand for extending the warranty period of vehicles, there still remains the problem that it is insufficient.

のである。In order to solve this problem, the method of the present invention coats the surface of each spring plate making up the stacked leaf spring with a highly concentrated zinc powder paint, and then coats the top with wax or asphalt. Alternatively, it is characterized in that it is coated with a petroleum-based rust inhibitor whose main composition is those warm substances.

。A coating film made of such a "petroleum-based rust inhibitor" has a treatment effect of sealing the pores of the high-concentration zinc dust paint film that is coated with a large number of pores. It prevents electrolytic solutions and other substances from entering the coating film, and even after drying, it is a semi-hardened plastic film, unlike a coating film made of general paint, so it can withstand harsh usage conditions where stress is applied repeatedly. Even under the conditions, the coating film does not crack, and the formation of gaps between the spring plates is suppressed.Furthermore, its lubricity prevents oxidized wear particles caused by friction between the spring plates. It also suppresses the production.
