Description

【考案の詳細な説明】 〔産業上の利用分野〕 本考案はリーフスプリングの給脂構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a greasing structure for a leaf spring.

〔従来の技術〕[Conventional technology]

例えば、自動車では、第３図に示すように、リーフスプ
リング01の一端又は両端のアイ02がそれぞれシャークル
ピン03を介してシャーシフレームに支持されるリーフス
プリングが知られている。この種のリーフスプリングは
そのたわみに伴い、その前後端がシャークルピンの周り
に相対的に若干回動する。For example, in automobiles, as shown in FIG. 3, a leaf spring is known in which the eye 02 at one end or both ends of the leaf spring 01 is supported by the chassis frame via the shankle pins 03, respectively. A leaf spring of this type has its front and rear ends relatively rotated around the sheer pin with the deflection thereof.

それ故、従来、第４図に示すように、最上層のアイを有
するリーフスプリング04と、その下の樹脂製リーフスプ
リング05との間にスライドシート06を挿入しているので
あるが、リーフスプリング04とスライドシート06との当
接面はキシキシと騒音を発生するとともに摩耗する。Therefore, conventionally, as shown in FIG. 4, the slide sheet 06 is inserted between the leaf spring 04 having the uppermost eye and the resin-made leaf spring 05 below the leaf spring 04. The abutting surface between 04 and the slide sheet 06 produces noise and noise and is worn.

〔考案が解決しようとする課題〕[Problems to be solved by the device]

本考案はこのような事情に鑑みて提案されたもので、騒
音及び摩耗を生じない静粛かつ長寿命のリーフスプリン
グの給脂構造を提供することを目的とする。The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a quiet and long-life greasing structure of a leaf spring that does not generate noise and wear.

〔課題を解決するための手段〕[Means for Solving the Problems]

そのために本考案は、後端にアイが形成された最上層の
鋼製リーフスプリングの両端部下面にスライドシートを
介して樹脂リーフスプリングが添設されてなる積層リー
フスプリングにおいて、上記各アイの下部にそれぞれ穿
設された透孔に充填されたグリスと、上記スライドシー
トの上面に凹設され上記透孔と交叉して長手方向に延び
る油溝とを具えたことを特徴とする。Therefore, the present invention is a laminated leaf spring in which resin leaf springs are attached to the lower surface of both ends of the uppermost steel leaf spring having an eye formed at the rear end via slide sheets, and And a oil groove extending in the longitudinal direction intersecting with the through hole and provided in the upper surface of the slide sheet.

〔作用〕[Action]

このような構成によれば、透孔に充填された油脂はシャ
ークルピンを潤滑するとともに、油溝を経てリーフスプ
リングとスライドシートの摺接面をも潤滑する。According to such a configuration, the oil and fat filled in the through hole lubricates the sharkcle pin and also lubricates the sliding contact surface between the leaf spring and the slide sheet through the oil groove.

その結果、リーフスプリングは騒音を発しなくなるとと
もに、摩耗が減少する。As a result, the leaf springs are less noisy and wear is reduced.

〔実施例〕〔Example〕

本考案の一実施例を図面について説明すると、第１図は
その端部を示す側面図、第２図は第１図のII−II断面図
である。An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an end thereof, and FIG. 2 is a sectional view taken along line II-II of FIG.

上図において、第３〜４図と同一の付番はそれぞれ同図
と同一の部材を示し、１は最上層のスチールリーフスプ
リングのアイ02の下部に穿設された透孔３に充填された
グリス、４はスライドシート06のスチールリーフスプリ
ングに当接する面に形成された長手方向の油溝である。In the above drawing, the same reference numerals as those in FIGS. 3 to 4 respectively show the same members as those in the same drawing, and 1 is filled in the through hole 3 formed in the lower portion of the eye 02 of the uppermost steel leaf spring. Greases 4 are longitudinal oil grooves formed on the surface of the slide seat 06 that abuts on the steel leaf spring.

このような構造によれば、透孔３に充填されたグリス１
はシャークルピン02を潤滑するとともに、油溝３を経て
リーフスプリングのスライドシートに当接する部分をも
潤滑する。According to such a structure, the grease 1 filled in the through holes 3
Lubricates the shankle pin 02 and also lubricates the portion of the leaf spring that comes into contact with the slide seat through the oil groove 3.

その結果、リーフスプリングは騒音を発生しなくなると
ともに、摩耗が減少する。As a result, the leaf springs are less noisy and wear is reduced.

〔考案の効果〕[Effect of device]

要するに本考案によれば、後端にアイが形成された最上

るから、本考案は産業上極めて有益なものである。In short, according to the present invention, in the laminated leaf spring in which the resin leaf springs are attached to the lower surface of both ends of the uppermost steel leaf spring having the eyes formed at the rear ends via the slide sheets, Noise and wear are caused by the provision of grease filled in the through holes formed in the lower portion and oil grooves extending in the longitudinal direction that intersect with the through holes and are provided in the upper surface of the slide sheet. The present invention is extremely useful in industry because it provides a quiet and long-life greasing structure for leaf springs.
