Description

この発明は、例えばトラックの駆動輪用ハブベアリングとして使用される車輪用軸受装置に関する。   The present invention relates to a wheel bearing device used as a hub bearing for a driving wheel of a truck, for example.

トラックの従動輪用ハブベアリングの構造が、例えば特許文献１の図３に示されている。このハブベアリングは、単列円すいころ軸受２個をユニット化し、かつ外輪とハブ輪とを一体化させた複列円すいころ軸受であって、内輪を車軸に嵌め合わせ、外輪のフランジにホイールおよびブレーキロータを取付けている。   A structure of a hub bearing for a driven wheel of a truck is shown in FIG. This hub bearing is a double-row tapered roller bearing in which two single-row tapered roller bearings are unitized and the outer ring and the hub ring are integrated. The rotor is installed.

上記従動輪用ハブベアリングでは、フランジの軸方向同じ側の側面にホイールおよびブレーキロータが取付けられているのに対し、駆動輪用ハブベアリングの場合、図５に示すように、フランジ９の両側の側面にホイール２０およびブレーキロータ２１をそれぞれ個別に取付けた構造とすることがある。なお、この駆動輪用ハブベアリングは外輪回転タイプであり、図６に示すように、車体に固定された筒軸２４の外周に内輪２を嵌め込み、上記筒軸２４の内周部に車軸２５を回転自在に挿通し、その車軸２５の外端に形成された拡径部２５ａをボルト２６により外輪３に結合させて、車軸２５と外輪３とが一体に回転するように組み付けられる。
特開平１１−３０３８６１号公報 In the driven wheel hub bearing described above, the wheel and the brake rotor are mounted on the side surface on the same axial side of the flange, whereas in the case of the driving wheel hub bearing, as shown in FIG. The wheel 20 and the brake rotor 21 may be individually attached to the side surfaces. The drive wheel hub bearing is an outer ring rotating type. As shown in FIG. 6, the inner ring 2 is fitted on the outer periphery of the cylindrical shaft 24 fixed to the vehicle body, and the axle 25 is mounted on the inner peripheral portion of the cylindrical shaft 24. The diameter-expanded portion 25a formed at the outer end of the axle 25 is coupled to the outer ring 3 by a bolt 26 so that the axle 25 and the outer ring 3 are integrally rotated.
JP-A-11-303861

図５に示す従来のトラックの駆動輪用ハブベアリングは、外輪３におけるフランジ９の軸方向両側部分がホイール２０およびブレーキロータ２１の内径面を案内するパイロット部２７，２８として大径に形成されているため、外輪３のフランジ周りが厚肉となり、外輪３の重量が大きかった。フランジ９のアウトボード側（車両外側寄りとなる側）にホイール２０のパイロット部２７を設ける場合、このホイールパイロット部２７よりもさらにアウトボード側に、車軸を結合するスリーブ部７が形成されているため、ホイールパイロット部２７の外径をスリーブ部７の外径よりも大きくする必要がある。このため、ホイールパイロット部２７の肉厚を小さくすることが難しく、外輪３ひいてはハブベアリング全体の重量増の大きな要因となっていた。   In the conventional drive wheel hub bearing of the truck shown in FIG. 5, both axial portions of the flange 9 in the outer ring 3 are formed in large diameters as pilot portions 27 and 28 for guiding the inner diameter surfaces of the wheel 20 and the brake rotor 21. Therefore, the periphery of the flange of the outer ring 3 is thick, and the weight of the outer ring 3 is large. When the pilot portion 27 of the wheel 20 is provided on the outboard side of the flange 9 (the side closer to the vehicle outer side), the sleeve portion 7 for coupling the axle is formed further on the outboard side than the wheel pilot portion 27. Therefore, the outer diameter of the wheel pilot portion 27 needs to be larger than the outer diameter of the sleeve portion 7. For this reason, it is difficult to reduce the thickness of the wheel pilot portion 27, which is a major factor in increasing the weight of the outer ring 3 and thus the entire hub bearing.

この発明の目的は、例えばトラックの駆動輪用ハブベアリングとして用いられる車輪用軸受装置において、ホイール取付用フランジの軸方向両側の側面にホイールおよびブレーキロータをそれぞれ個別に取付ける構成とする場合に、ホイールパイロットを有しながら、外輪におけるフランジよりもホイール配置側の肉厚を小さくして、軽量化を図ることである。   An object of the present invention is to provide a wheel bearing device used as a hub bearing for a driving wheel of a truck, for example, in a case where a wheel and a brake rotor are individually attached to side surfaces on both axial sides of a wheel mounting flange. While having a pilot, the thickness on the wheel arrangement side is made smaller than the flange in the outer ring to reduce the weight.

この発明にかかる車輪用軸受装置は、内輪と、外輪と、これら内外輪間に組み込まれた複列の転動体と、各列の転動体を保持する保持器とを備え、前記外輪の外周にホイール取付用のフランジを有する車輪用軸受装置において、前記フランジの片側の側面に、ホイールの内径面を案内するホイールパイロットを、前記外輪とは別部品として設け、前記外輪の外周面における前記フランジの他の片側に隣合う箇所に、ブレーキロータの内径面を案内するブレーキロータパイロットを外輪と一体に設けた。   A wheel bearing device according to the present invention includes an inner ring, an outer ring, a double row rolling element incorporated between the inner and outer rings, and a cage that holds the rolling element in each row, and is provided on an outer periphery of the outer ring. In the wheel bearing device having a flange for mounting a wheel, a wheel pilot for guiding an inner diameter surface of the wheel is provided on one side surface of the flange as a separate component from the outer ring, and the flange on the outer peripheral surface of the outer ring is provided. A brake rotor pilot that guides the inner diameter surface of the brake rotor is provided integrally with the outer ring at a location adjacent to the other side.

この構成によると、ホイールパイロットを外輪とは別部品とすることにより、外輪におけるフランジよりもホイール配置側の肉厚を大きくすることなく、ホイールパイロットによってホイールの内径面を案内することができる。前記肉厚を小さくできでき、またホイールパイロットが外輪とは別部材であって、ホイールの案内を行なうのに必要なだけの小さな部品とできるためるため、外輪ひいては車輪用軸受装置の軽量化を図れる。   According to this configuration, by making the wheel pilot a separate component from the outer ring, the wheel pilot can guide the inner diameter surface of the wheel without increasing the thickness of the wheel arrangement side than the flange in the outer ring. The thickness can be reduced, and the wheel pilot is a separate member from the outer ring and can be made as small as necessary to guide the wheel, so the outer ring and thus the wheel bearing device can be reduced in weight. .

この発明において、前記ホイールパイロットが、断面Ｌ字形の円環状部品であって、前記フランジにボルトで取付けられたものとすることができる。また、前記ホイールパイロットが、前記フランジの円周方向に並べてボルトにより前記フランジにそれぞれ取付けられた複数の断面Ｌ字形のパイロット構成部品からなるものとしても良い。さらに、前記ホイールパイロットが、前記フランジの円周方向に並べて配置された複数のピンからなり、これら各ピンは、前記フランジの側面に設けた孔に基端を圧入することにより前記フランジに取付けられるものとしても良い。
いずれの場合も、ホイールパイロットの加工が容易で、かつフランジに容易に取付けることができる。外輪およびホイールの寸法、形状等の各種条件に合わせて、適正なホイールパイロットの形態を選択すれば良い。 In the present invention, the wheel pilot may be an annular part having an L-shaped cross section and attached to the flange with a bolt. The wheel pilot may be composed of a plurality of L-shaped pilot components arranged in the circumferential direction of the flange and attached to the flange by bolts. Further, the wheel pilot is composed of a plurality of pins arranged side by side in the circumferential direction of the flange, and each of these pins is attached to the flange by press-fitting a base end into a hole provided on a side surface of the flange. It is good as a thing.
In either case, the wheel pilot can be easily processed and can be easily attached to the flange. An appropriate wheel pilot form may be selected in accordance with various conditions such as the dimensions and shape of the outer ring and the wheel.

この発明の車輪用軸受装置は、内輪と、外輪と、これら内外輪間に組み込まれた複列の転動体と、各列の転動体を保持する保持器とを備え、前記外輪の外周にホイール取付用のフランジを有する車輪用軸受装置において、前記フランジの片側の側面に、ホイールの内径面を案内するホイールパイロットを、前記外輪とは別部品として設け、前記外輪の外周面における前記フランジの他の片側に隣合う箇所に、ブレーキロータの内径面を案内するブレーキロータパイロットを外輪と一体に設けたため、外輪におけるフランジよりもホイール配置側の肉厚を小さくして、軽量化を図ることができる。   The wheel bearing device of the present invention includes an inner ring, an outer ring, a double row rolling element incorporated between the inner and outer rings, and a cage for holding the rolling element in each row, and a wheel is provided on the outer periphery of the outer ring. In the wheel bearing device having a mounting flange, a wheel pilot that guides the inner diameter surface of the wheel is provided on one side surface of the flange as a separate component from the outer ring, and the flange on the outer peripheral surface of the outer ring is provided. Since the brake rotor pilot that guides the inner diameter surface of the brake rotor is provided integrally with the outer ring at a position adjacent to one side of the outer ring, the thickness on the wheel arrangement side can be made smaller than the flange in the outer ring, and the weight can be reduced. .

この発明の第１の実施形態を図１および図２と共に説明する。この実施形態は、外輪回転タイプで、例えばトラックの駆動輪用ハブベアリングに適用されるものである。なお、この明細書において、車両に取付けた状態で車両の車幅方向の外側寄りとなる側をアウトボード側と呼び、車両の中央寄りとなる側をインボード側と呼ぶ。   A first embodiment of the present invention will be described with reference to FIGS. This embodiment is an outer ring rotating type and is applied to a hub bearing for a driving wheel of a truck, for example. In this specification, the side closer to the outer side in the vehicle width direction of the vehicle when attached to the vehicle is referred to as the outboard side, and the side closer to the center of the vehicle is referred to as the inboard side.

この車輪用軸受装置は、それぞれ外周面に複列の軌道面２ａを有する内輪２と、この内輪２の軌道面２ａに対向する複列の軌道面３ａを内周面に有する外輪３と、これら内外輪２，３間に組み込まれた複列の転動体４とを備えている。この実施形態の場合、転動体４は円すいころであって、複列の円すいころが背面組合せで配列され、各列毎に保持器５で保持されている。   The wheel bearing device includes an inner ring 2 having a double-row raceway surface 2a on the outer peripheral surface, an outer ring 3 having a double-row raceway surface 3a opposite to the raceway surface 2a of the inner ring 2 on the inner peripheral surface, A double row rolling element 4 is provided between the inner and outer rings 2 and 3. In the case of this embodiment, the rolling element 4 is a tapered roller, and double rows of tapered rollers are arranged in a back surface combination and held by the cage 5 for each row.

外輪３は、アウトボード側の軌道面３ａよりもさらにアウトボード側に突出するスリーブ部７を有し、このスリーブ部７の端面に、内周に雌ねじ部８ａを形成した車軸結合孔８が周方向複数箇所に設けられている。図示は省略するが、図６に示す従来の駆動輪用ハブベアリングの場合と同様に、車体に固定された筒軸の外周に内輪２を嵌め込み、上記筒軸の内周部に車軸を回転自在に挿通し、その車軸のアウトボード側端に形成された拡径部を、車軸結合孔８に螺着したボルトにより外輪３に結合する。   The outer ring 3 has a sleeve portion 7 that protrudes further toward the outboard side than the raceway surface 3a on the outboard side, and an axle coupling hole 8 having an internal thread portion 8a formed on the inner periphery is provided on the end surface of the sleeve portion 7. It is provided at multiple locations in the direction. Although not shown, as in the case of the conventional drive wheel hub bearing shown in FIG. 6, the inner ring 2 is fitted on the outer periphery of the cylindrical shaft fixed to the vehicle body, and the axle is freely rotatable on the inner peripheral portion of the cylindrical shaft. The diameter-enlarged portion formed at the end on the outboard side of the axle is coupled to the outer ring 3 by a bolt screwed into the axle coupling hole 8.

また、外輪３は、外周のアウトボード側およびインボード側の両軌道面３ａのほぼ中間の軸方向位置に、ホイールおよびブレーキロータ取付用のフランジ９を有し、このフランジ９の周方向複数箇所にボルト挿通孔１０が設けられている。外輪３におけるフランジ９よりもインボード側は、フランジ９の近辺部分１１が大径に形成され、その外周面がブレーキロータパイロット１２とされている。   The outer ring 3 has flanges 9 for attaching wheels and brake rotors at substantially intermediate axial positions between the outer raceway surfaces 3a on the outer board side and the inboard side. A bolt insertion hole 10 is provided in the front. On the inboard side of the outer ring 3 with respect to the flange 9, a vicinity portion 11 of the flange 9 is formed with a large diameter, and an outer peripheral surface thereof is a brake rotor pilot 12.

一方、外輪３におけるフランジ９よりもアウトボード側は、フランジ９の基端９ａから前記スリーブ部７の先端に至るまで同一外径に形成されている。そして、フランジ９のアウトボード側の側面に、外輪３とは別部材のホイールパイロット１４が設けられている。ここで、フランジ９のアウトボード側の側面とは、フランジ９の外周端から基端９ａまでの範囲のことである。この実施形態では、ホイールパイロット１４は、外周縁１４ａがアウトボード側に張り出す断面Ｌ字形の円環状部品であり、円周方向の複数箇所に設けられたボルト孔１４ｂに挿通したボルト１５により、フランジ９に取付けられている。   On the other hand, the outboard side of the flange 3 in the outer ring 3 is formed to have the same outer diameter from the base end 9 a of the flange 9 to the tip of the sleeve portion 7. A wheel pilot 14, which is a separate member from the outer ring 3, is provided on the side surface of the flange 9 on the outboard side. Here, the side surface on the outboard side of the flange 9 is a range from the outer peripheral end of the flange 9 to the base end 9a. In this embodiment, the wheel pilot 14 is an annular part having an L-shaped cross-section with an outer peripheral edge 14a projecting to the outboard side, and by bolts 15 inserted through bolt holes 14b provided at a plurality of locations in the circumferential direction, Attached to the flange 9.

この車輪用軸受装置をトラックの駆動輪用ハブベアリングとして組付ける場合、図１に二点鎖線で示すように、フランジ９のアウトボード側に隣合う箇所にホイール２０を配置し、かつフランジ９のインボード側に隣合う箇所にブレーキロータ２１を配置し、これらホイール２０およびブレーキロータ２１を、前記ボルト挿通孔１０に挿通したボルト２２およびナット２３によりフランジ９に取付ける。その際、ホイール２０の内周面はホイールパイロット１４の外周縁１４ａにより案内され、ブレーキロータ２１の内周面はブレーキロータパイロット１２により案内される。   When this wheel bearing device is assembled as a hub bearing for a drive wheel of a truck, as shown by a two-dot chain line in FIG. The brake rotor 21 is disposed at a location adjacent to the inboard side, and the wheel 20 and the brake rotor 21 are attached to the flange 9 by bolts 22 and nuts 23 inserted through the bolt insertion holes 10. At that time, the inner peripheral surface of the wheel 20 is guided by the outer peripheral edge 14 a of the wheel pilot 14, and the inner peripheral surface of the brake rotor 21 is guided by the brake rotor pilot 12.

この車輪用軸受装置は、図５に示す従来のものと比べ、外輪３におけるフランジ９よりもアウトボード側の部分の肉厚が薄く、ホイールパイロット１４が小型で軽量の部品からなるため、外輪３ひいては車輪用軸受装置全体の軽量化を図ることができる。また、ホイールロータパイロット１４は、板金のプレス加工等により容易に加工することができ、かつフランジ９への取付けも容易である。   Compared with the conventional one shown in FIG. 5, the wheel bearing device has a thinner part on the outboard side than the flange 9 in the outer ring 3, and the wheel pilot 14 is made of small and lightweight parts. As a result, the weight of the entire wheel bearing device can be reduced. The wheel rotor pilot 14 can be easily processed by sheet metal pressing or the like, and can be easily attached to the flange 9.

図３は異なる実施形態を示す。この車輪用軸受装置のホイールパイロットは、前記実施形態のホイールパイロット１４と同じ断面形状をした複数のパイロット構成部品１６からなり、各パイロット構成部品１６がフランジ９のアウトボード側の側面の同一円周上にボルト１５により取付けられている。この複数のパイロット構成部品１６からなるホイールパイロットは、前記実施形態のホイールパイロット１４に比べ、材料の使用量が少ないため、さらに軽量化を図ることができる。   FIG. 3 shows a different embodiment. The wheel pilot of this wheel bearing device is composed of a plurality of pilot components 16 having the same cross-sectional shape as the wheel pilot 14 of the above embodiment, and each pilot component 16 has the same circumference on the side surface of the flange 9 on the outboard side. A bolt 15 is attached to the top. Since the wheel pilot composed of the plurality of pilot components 16 uses less material than the wheel pilot 14 of the above-described embodiment, the weight can be further reduced.

図４はさらに異なる実施形態を示す。この車輪用軸受装置のホイールパイロットは、複数のピン１７からなり、フランジ９のアウトボード側の側面の同一円周上に設けた孔１８に基端を圧入することにより、各ピン１７がフランジ９に取付けられている。この複数のピン１７からなるホイールパイロットは、前記各実施形態のホイールパイロット１４，１６に比べ、さらに簡略なものであるため、より一層の軽量化を図ることができる。   FIG. 4 shows a further different embodiment. The wheel pilot of this wheel bearing device is composed of a plurality of pins 17, and each pin 17 is inserted into the flange 9 by press-fitting a base end into a hole 18 provided on the same circumference of the side surface of the flange 9 on the outboard side. Installed on. Since the wheel pilot composed of the plurality of pins 17 is simpler than the wheel pilots 14 and 16 of the above-described embodiments, the weight can be further reduced.
