Description
【考案の詳細な説明】 本考案はフォークリフトの駆動軸管取付装置に関する。[Detailed explanation of the idea] The present invention relates to a forklift drive shaft tube mounting device.
従来は、第2図に示すように、駆動軸管1をチャンネル
状フレーム2のみそ部に取付けるときは、ボルト3及び
ナツト4のみによる嵌合締着をしていた。Conventionally, as shown in FIG. 2, when attaching the drive shaft tube 1 to the edge of the channel-shaped frame 2, only bolts 3 and nuts 4 were used for fitting and tightening.
また1、駆動軸管1のフランジ部1Bの側壁1人とチャ
ンネル状フレーム2の側壁2Aは、該駆動軸管1とチャ
ンネル状フレーム2との接触面9に対してほぼ直角形状
を成し2て、それぞれ相接して仰り付けられていた。In addition, 1, the side wall of the flange portion 1B of the drive shaft tube 1 and the side wall 2A of the channel-shaped frame 2 form a shape that is approximately perpendicular to the contact surface 9 between the drive shaft tube 1 and the channel-shaped frame 2; Each of them was asked to do so one after the other.
したがって、駆動軸管1をチャンネル状フレーム2に容
易に取付けることを考慮して、側壁IA、2Aの間には
若干の隙間5を有する構造にしなければならなかった。Therefore, in order to easily attach the drive shaft tube 1 to the channel-shaped frame 2, the structure had to have a slight gap 5 between the side walls IA and 2A.
このような構造の結果、下記する種々の欠陥が生じた。As a result of this structure, various defects have occurred as described below.
第1図において、マスト6の前後傾作動すなわちティル

に移行したとき、慣性力及び反力がティルトシリンダ7
の基部7A及びマスト6の下端部すなわちマストサポー
)6Aを経てアクスルシャフト8を内装する駆動軸管1
に作用する。In FIG. 1, when the mast 6 is tilted back and forth, or when it transitions from running to stopping or from stopping to running, inertia force and reaction force are applied to the tilt cylinder 7.
The drive shaft tube 1 that houses the axle shaft 8 through the base 7A of the mast 6 and the lower end (mast support) 6A of the mast 6
It acts on
なお、フォーク17上に積荷がある場合は、前記慣性力
及び反力はさらに大きく作用する。Note that when there is a load on the fork 17, the inertial force and reaction force act even more strongly.
よって、上記ティトル操作時又は制動時などには、駆動
軸管1とチャンネル状フレーム2との接触面9に対して
前後方向に相対移動が発生する。Therefore, during the above-mentioned titling operation or braking, relative movement occurs in the front-back direction with respect to the contact surface 9 between the drive shaft tube 1 and the channel-shaped frame 2.
その相対移動を発生させる外力に対抗すべく大きな締付
トルクでボルト3を締結しなければならなかった。The bolt 3 had to be fastened with a large tightening torque in order to counteract the external force that causes the relative movement.
そのため、ボルト3及びナツト4のそれぞれの座面3A
、4Aの面圧が高くなり、前記相対移動によって、数
面に摩耗が発生し、結果的にはボルトのゆるみが起った
。Therefore, each bearing surface 3A of the bolt 3 and nut 4
, 4A increased, and due to the relative movement, wear occurred on several surfaces, resulting in loosening of the bolts.
更に、ボルト3のゆるみが進行すると、前記した構造の
ために、駆動軸管1とチャンネルフレーム2とはストッ
プ効果が完全でなくなり、前後方向に発生する相対移動
によって、ボルト3に剪断応力がかかり、長期間この現
象がくり返えされると、ボルト3の折損に1で至ること
があった。Furthermore, as the bolts 3 become loosened, due to the structure described above, the stopping effect between the drive shaft tube 1 and the channel frame 2 is no longer complete, and shear stress is applied to the bolts 3 due to the relative movement that occurs in the front and rear directions. If this phenomenon is repeated for a long period of time, the bolt 3 may break.
本案の目的は、上記の欠点を解消しようとするもので、
チャンネル状フレームと駆動軸管に外力が加えられても
、ボルトのゆるみ及び折損等を排除して、該チャンネル
状フレームと該駆動軸管が堅ろうに固着される取付は装
置を提供することである。The purpose of this proposal is to eliminate the above drawbacks.
It is an object of the present invention to provide a mounting device in which the channel-shaped frame and the drive shaft tube are firmly fixed, eliminating loosening and breakage of bolts, even if an external force is applied to the channel-shaped frame and the drive shaft tube. .
以下、第3図、第4図の実施例に基づき、本考案を詳細
に説明する。Hereinafter, the present invention will be explained in detail based on the embodiments shown in FIGS. 3 and 4.

ランジ部1Bとはボルト3によって締結されている。In FIG. 3, the channel-shaped frame 12 is fixed together with a rib 11 to the lower front end of the side frame 10 that supports the upper frame 16. 1B are fitted, and the channel-shaped frame 12 and the flange portion 1B are fastened with bolts 3.
なお、13はディファレンシャルケースを示している。Note that 13 indicates a differential case.

2Aとの間に空間部を形成する。In FIG. 4, the side wall 1 of the flange portion 1B of the drive shaft tube 1
Side walls 12A, 2A of the channel-shaped frame opposite A
A side wall 12A having an inclined surface is formed at one end of the flange portion 1B and a side wall 1 of the channel-shaped frame.
A space is formed between 2A and 2A.
該空間部には、前記傾斜面と合致した傾斜面を有するく
さび形部材14を前後方向に嵌挿し、締付はボルト15
をチャンネル状フレーム端部に穿設されたねじ孔12に
至る1でねじ込み、くさび形部材14を固定する。A wedge-shaped member 14 having an inclined surface matching the above-mentioned inclined surface is inserted into the space in the front-rear direction, and tightened with a bolt 15.
is screwed into the screw hole 12 drilled in the end of the channel-shaped frame to fix the wedge-shaped member 14.
なお、傾斜面空間部を有する側壁1A、12Aの他端側
壁IA。Note that the side wall IA at the other end of the side walls 1A and 12A has an inclined surface space.
2Aは、従来技術と同じ形状を威して締結されている。2A is fastened using the same shape as the prior art.
くさび状部材14のボルト15を締めつけると、駆動軸

材14が側壁IA、12Aに介在することによって駆動
軸管1とチャンネル状フレーム2が相対移動をしない堅
固な取付は状態となる。When the bolts 15 of the wedge-shaped member 14 are tightened, there is no gap between the flange portion 1B of the drive shaft tube 1 and the side walls IA, 2A, and 12A of the channel-shaped frame 2, so that the drive shaft tube 1 and Channel frame 2
Even if an inertial force or a reaction force is applied to the contact surface 9 with the drive shaft tube 1 and the channel-shaped frame 2, the wedge-shaped member 14 is interposed between the side walls IA and 12A, so that the rigid mounting does not cause relative movement. Become.
なお、くさび形部材14のボルト孔14Aは、ボルト径
に比して若干大きくしであるので、くさび形部材14を
隙間のなくなるオでボルト15で締め上げても、ボルト
15とくさび形部材14とがボルト孔14Aの内部で当
らないようにしである。Note that the bolt hole 14A of the wedge-shaped member 14 is slightly larger than the bolt diameter, so even if the wedge-shaped member 14 is tightened with the bolt 15 with no gap, the bolt 15 and the wedge-shaped member 14 This is to prevent the bolts from hitting inside the bolt hole 14A.
したがって、くさび形部材14を側壁IA、2Aの間に

する必要がない。Therefore, by inserting and fastening the wedge-shaped member 14 between the side walls IA and 2A, even if an inertial force or a reaction force acts between the drive shaft tube 1 and the channel-shaped frame 12, there is no force between them. Since fastening is achieved without relative movement, loosening or breakage of the bolt 3 is avoided, ensuring safety when driving a forklift. No need to shape it.
また、ボルト3を必要以上に大トルクで締結しなくても
よいので、保守作業などが極めて容易である。Further, since the bolt 3 does not have to be fastened with an unnecessarily large torque, maintenance work and the like are extremely easy.
