Description

本発明はフロントアクスル用のハブ取付治具に関し、更に詳しくは、自動車のフロントアクスルにタイヤホイール組立体を容易かつ正確に組み付けることができるフロントアクスル用のハブ取付治具に関する。   The present invention relates to a hub mounting jig for a front axle, and more particularly to a hub mounting jig for a front axle that can easily and accurately assemble a tire wheel assembly to a front axle of an automobile.

トラックなどの自動車は、図９に示すように、荷重分担及び操舵などを目的とするフロントアクスル２０を備えている（例えば、特許文献１を参照）。このフロントアクスル２０においては、固定車軸の役目を有するナックル部２１に、ホイール２２にタイヤ２３を取り付けてなるタイヤホイール組立体２４に装着されたハブ２５を外挿させて組み付けるようになっている。   As shown in FIG. 9, a vehicle such as a truck includes a front axle 20 for load sharing and steering (see, for example, Patent Document 1). In the front axle 20, a hub 25 attached to a tire wheel assembly 24 in which a tire 23 is attached to a wheel 22 is attached to a knuckle portion 21 serving as a fixed axle so as to be assembled.

従来、このタイヤホイール組立体２４の具体的な組付作業は、タイヤ２３側面の２箇所（図９中の矢印を参照）を大型ハンマーで交互に打撃して、ナックル部２１にハブ２５を中間ばめすることにより行われていた。   Conventionally, a specific assembling operation of the tire wheel assembly 24 is performed by hitting two places on the side of the tire 23 (see arrows in FIG. 9) alternately with a large hammer, and interposing the hub 25 on the knuckle portion 21. It was done by fitting.

このナックル部２１は、図１０に示すように、根元の中間ばめ部２６から細径の先端部２７へかけてテーパ部２８が形成された形状を有している。そのため、上記のような組付作業では、タイヤホイール組立体２４とナックル部２１との中心軸が合いにくくなるため、ハブ２５がテーパ部２８に引っかかってタイヤホイール組立体２４の組み付けが困難になるという問題があった。また、タイヤホイール組立体２４に加わる圧力が不均等かつ不連続になるため、タイヤホイール組立体２４を正確に組み付けることが難しいという問題もあった。   As shown in FIG. 10, the knuckle portion 21 has a shape in which a tapered portion 28 is formed from the intermediate fitting portion 26 at the base to the distal end portion 27 having a small diameter. Therefore, in the above assembling work, the center axis of the tire wheel assembly 24 and the knuckle portion 21 is difficult to be aligned, so that the hub 25 is caught by the tapered portion 28 and the assembling of the tire wheel assembly 24 becomes difficult. There was a problem. Further, since the pressure applied to the tire wheel assembly 24 is uneven and discontinuous, there is a problem that it is difficult to correctly assemble the tire wheel assembly 24.

このフロントアクスル用のハブ取付治具（以下、単に「ハブ取付治具」という。）は、図１に示すように、アタッチメント１と、略径方向に延びるハンドル２が外面に固定された本体３とを組み合わせたものである。   As shown in FIG. 1, the front axle hub mounting jig (hereinafter simply referred to as “hub mounting jig”) includes an attachment 1 and a main body 3 having a handle 2 extending substantially in the radial direction fixed to the outer surface. Are combined.

アタッチメント１は金属製であり、図２に示すように、雄ネジ４が表面に形成された円柱状のシャフト部５と、そのシャフト部５の一端に外嵌固定された円筒状のソケット部６とから構成される。ソケット部６には、フロントアスクル２０のナックル部２１の先端部２７（図１０を参照）に予め形成される雄ネジに螺合可能な雌ネジ７が形成されている。また、シャフト部５の他端は、軸方向に沿って一対の平面８を形成することで細径になっており、更にそれらの平面８間を貫通する小孔９が設けられている。   The attachment 1 is made of metal, and as shown in FIG. 2, a cylindrical shaft portion 5 having a male screw 4 formed on the surface thereof, and a cylindrical socket portion 6 that is externally fixed to one end of the shaft portion 5. It consists of. The socket portion 6 is formed with a female screw 7 that can be screwed into a male screw that is formed in advance at the tip portion 27 (see FIG. 10) of the knuckle portion 21 of the front axle 20. The other end of the shaft portion 5 has a small diameter by forming a pair of planes 8 along the axial direction, and further provided with a small hole 9 penetrating between the planes 8.

本体３は略円筒状の形状を有しており、図３に示すように、アタッチメント１のシャフト部５に形成された雄ネジ４に螺合する雌ネジ１０が形成された金属製の頭部１１と、その頭部１１の端部に固定された金属製の押圧部１２とを有している。   The main body 3 has a substantially cylindrical shape, and as shown in FIG. 3, a metal head in which a female screw 10 that is screwed into a male screw 4 formed on the shaft portion 5 of the attachment 1 is formed. 11 and a metal pressing portion 12 fixed to the end portion of the head portion 11.

頭部１１の表面には、上述した一対のハンドル２が固定されている。また、押圧部１２には、アタッチメント１のソケット部６が嵌合する嵌合孔１３が形成されている。更に、押圧部１２の開口部１４側には、タイヤホイール組立体２４のハブ２５の内径よりも太径であるＭＣナイロン等の樹脂製の太径部１５が外嵌しているとともに、その端縁部にはテーパ１６が形成されている。   The pair of handles 2 described above are fixed to the surface of the head 11. In addition, the pressing portion 12 is formed with a fitting hole 13 into which the socket portion 6 of the attachment 1 is fitted. Further, a resin-made large-diameter portion 15 such as MC nylon having a larger diameter than the inner diameter of the hub 25 of the tire wheel assembly 24 is fitted on the opening portion 14 side of the pressing portion 12, and the end thereof A taper 16 is formed at the edge.

このようなハブ取付治具を用いたフロントアクスル２０へのタイヤホイール組立体２４の組付作業を以下に説明する。なお、フロントアクスル２０に組み付けられるタイヤホイール組立体２４は、図４の例に示すように、一般的にハブ２５及びブレーキドラム２９が装着されたホイール２２にタイヤ２３が取り付けられた構造を有するが、この組付作業に関係するのはハブ２５のみであるため、以下の図５〜８においては、ホイール２２及びタイヤ２３を省略している。   The assembly work of the tire wheel assembly 24 to the front axle 20 using such a hub mounting jig will be described below. The tire wheel assembly 24 assembled to the front axle 20 generally has a structure in which a tire 23 is attached to a wheel 22 on which a hub 25 and a brake drum 29 are mounted, as shown in the example of FIG. Since only the hub 25 is related to the assembling work, the wheels 22 and the tires 23 are omitted in the following FIGS.

最初に、図５に示すように、ナックル部２１の先端部２７に予め形成された雄ネジに、ソケット部６の雌ネジ７を螺合させることで、アタッチメント１をナックル部２１に同軸になるように取り付ける。このとき、シャフト部５の他端の小孔９にドライバー等の棒状の工具を挿入してトルクをかけることで、アタッチメント１とナックル部２１との取付状態を確実にすることができる。   First, as shown in FIG. 5, the attachment 1 is coaxial with the knuckle portion 21 by screwing the female screw 7 of the socket portion 6 into a male screw formed in advance at the distal end portion 27 of the knuckle portion 21. Install as follows. At this time, the attachment state between the attachment 1 and the knuckle portion 21 can be ensured by inserting a rod-like tool such as a screwdriver into the small hole 9 at the other end of the shaft portion 5 and applying torque.

次に、図６に示すように、ハブ２５にナックル部２１を通過させて、アタッチメント１のシャフト部５の先端部分を外側へ突出させる。   Next, as shown in FIG. 6, the knuckle portion 21 is passed through the hub 25 so that the tip portion of the shaft portion 5 of the attachment 1 protrudes outward.

そして、図７に示すように、外側へ突出したアタッチメント１に本体３を押圧部１２側から取り付けて、シャフト部５の雄ネジ４に頭部１１の雌ネジ１０を螺合させつつハンドル２を介して本体３を回転させる。このとき、シャフト部５の他端が細径になっているため、雄ネジ４と雌ネジ１０の螺合の開始が容易になる。   Then, as shown in FIG. 7, the main body 3 is attached to the attachment 1 protruding outward from the pressing portion 12 side, and the handle 2 is screwed while the female screw 10 of the head portion 11 is screwed to the male screw 4 of the shaft portion 5. The main body 3 is rotated. At this time, since the other end of the shaft portion 5 has a small diameter, the screwing of the male screw 4 and the female screw 10 can be easily started.

本体３を回転させていくと、太径部１５のテーパ１６がハブ２５の端部に当接して、ハブ２５とともにタイヤホイール組立体２４が本体３によりフロントアクスル２０へ向けて押し込まれる。タイヤホイール組立体２４が押し込まれる際には、ナックル部２１とタイヤホイール組立体２４とは同軸状態になるため、ハブ２５がナックル部２１のテーパ部２８に引っかかることはない。また、太径部１５がＭＣナイロン等の軟らかい樹脂製であるため、ハブ２５の損傷を防止することができる。   As the main body 3 is rotated, the taper 16 of the large diameter portion 15 comes into contact with the end portion of the hub 25, and the tire wheel assembly 24 is pushed together with the hub 25 toward the front axle 20 by the main body 3. When the tire wheel assembly 24 is pushed in, the knuckle portion 21 and the tire wheel assembly 24 are in a coaxial state, so that the hub 25 is not caught by the taper portion 28 of the knuckle portion 21. Moreover, since the large diameter part 15 is made of soft resin such as MC nylon, the hub 25 can be prevented from being damaged.

最後に、図８に示すように、本体３の押圧部１２の嵌合孔１３に、アタッチメント１のソケット部６を嵌合させつつ、ハブ２５をナックル部２１の中間ばめ部２６に嵌め合わせる。このとき、タイヤホイール組立体２４には、本体３によりテーパ１６を介して径方向に均等に圧力が加わるため、タイヤホイール組立体２４をナックル部２１に正確に中間ばめすることができる。   Finally, as shown in FIG. 8, the hub 25 is fitted to the intermediate fitting portion 26 of the knuckle portion 21 while fitting the socket portion 6 of the attachment 1 into the fitting hole 13 of the pressing portion 12 of the main body 3. . At this time, since the tire wheel assembly 24 is equally pressurized in the radial direction via the taper 16 by the main body 3, the tire wheel assembly 24 can be accurately intermediately fitted to the knuckle portion 21.

以上のようにして、本発明のハブ取付治具を用いることで、自動車のフロントアクスル２０に、ハブ２５が装着されたタイヤホイール組立体２４を容易かつ正確に組み付けることができるのである。   As described above, by using the hub mounting jig of the present invention, the tire wheel assembly 24 to which the hub 25 is mounted can be easily and accurately assembled to the front axle 20 of the automobile.
