Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、クラッチを接、離作動するクラッチヨークが
スリーブから脱落することを防止する装置に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for preventing a clutch yoke, which engages and disengages a clutch, from falling out of the sleeve.
第3図〜第5図に示すように、入力側1と出力側2とを
接離するクラッチ部材3をクラッチヨーク4でスリーブ
5を摺動することで接離するクラッチが知られている。As shown in FIGS. 3 to 5, there is known a clutch in which a clutch member 3 for connecting and disconnecting an input side 1 and an output side 2 is brought into contact with and separated from by sliding a sleeve 5 with a clutch yoke 4.
すなわち、クラッチヨーク4はピボット6を中心として
揺動自在に支承され、その先端2又部4a,4aをスリ
ーブ5の両側に設けた突起5aに接し、他端部4bにシ
リンダー7の可動部7aを接してシリンダー7でクラッ
チヨーク4を揺動してスリーブ5を摺動できるようにし
ている。That is, the clutch yoke 4 is swingably supported about the pivot 6, and the tip ends 2a and 4a of the clutch yoke 4 are in contact with the protrusions 5a provided on both sides of the sleeve 5, and the movable part 7a of the cylinder 7 is attached to the other end 4b. The cylinder 7 swings the clutch yoke 4 to allow the sleeve 5 to slide.
このような構造であると、クラッチヨーク4とスリーブ
5が車体振動や動き不良により外れることがあり、例え
ば第6図、第7図に示すようにスプリング8を用いて外
れないようにしている。With such a structure, the clutch yoke 4 and the sleeve 5 may be disengaged due to vehicle body vibration or malfunction, and for example, as shown in FIGS. 6 and 7, a spring 8 is used to prevent disengagement.
つまり、スプリング8を第8図のように半円形部8aの
両側に折曲部8bを連続して一体形成し、その半円形部
8aをスリーブ5に遊嵌すると共に、折曲部8bの端部
8cを突起4aの穴9に嵌合して先端2又部4aを突起
5aに押しつけている。That is, as shown in FIG. 8, the spring 8 is formed by continuously and integrally forming the bent portions 8b on both sides of the semi-circular portion 8a. The semi-circular portion 8a is loosely fitted in the sleeve 5 and the end of the bent portion 8b is formed. The portion 8c is fitted into the hole 9 of the protrusion 4a, and the tip 2 or the portion 4a is pressed against the protrusion 5a.
かかる構造であると、スリーブ5の突起5aに穴9を穿
孔せねばならないと共に、組立後にスプリング8を折り
曲げているので、その折り曲げ具合が悪いとスプリング
8が外れることがあって、組立作業が大変面倒となって
しまう。With such a structure, since the hole 9 must be formed in the protrusion 5a of the sleeve 5 and the spring 8 is bent after assembly, the spring 8 may come off if the bending condition is not good, which makes the assembly work difficult. It becomes troublesome.
そこで、本考案は上記の問題点を解決できるようにした
