Description
この発明は、ハブ輪に2列の個別の内輪を圧入状態に嵌合させた車輪用軸受装置に関する。 The present invention relates to a wheel bearing device in which two rows of individual inner rings are fitted into a hub ring in a press-fit state.
この種の車輪用軸受装置では、ハブ輪に嵌合したアウトボード側の内輪をハブ輪の外周に形成された段差面に当接させると共に、インボード側の内輪の幅面をナットにより締め付けることで、2列の内輪を軸方向に位置決めしている(例えば特許文献1)。ナット締めの代わりに、ハブ輪のインボード側端に加締部を設けて2列の内輪を位置決めするものもある。
しかし、上記従来構造では、2列の内輪のハブ輪に対する締代公差が同じであるため、締代を小さくした場合、クリープ発生条件の厳しいアウトボード側の内輪にクリープが発生する。一方、締代を大きくすれば、著しい腐食環境下にあり加締止めとなることもあるインボード側の内輪に、フープ応力が発生し、その腐食による強度低下と相まって、軸受機能を損なう。
特許文献1に開示された車輪用軸受装置では、アウトボード側の内輪の軸方向寸法をインボード側の内輪の軸方向寸法よりも大きくすることで、アウトボード側の内輪でのクリープ発生を防止するようにしている。しかし、この構成では軸受装置の軸方向寸法が大きくなってしまう。
But in the conventional structure, since tightening margin tolerance for the inner ring of the wheel hub of the two rows are the same, the reduction in tightening margin, creep occurs in the inner ring of tough-out board side of creep occurring conditions. On the other hand, if the tightening allowance is increased, hoop stress is generated in the inner ring on the inboard side that is in a significantly corrosive environment and may be caulked, and the bearing function is impaired due to a decrease in strength due to the corrosion.
In the wheel bearing device disclosed in
この発明の目的は、2列の内輪のうち、クリープ発生条件の厳しいアウトボード側列の内輪ではクリープ発生を防止でき、かつ著しい腐食環境下にあるインボード側列の内輪ではフープ応力の発生の軽減による耐久性確保が図れ、また軸方向寸法も大きくならない車輪用軸受装置を提供することである。 The object of the present invention is to prevent the occurrence of creep in the inner ring of the outboard side row where the creep generation conditions are severe, and the occurrence of hoop stress in the inner ring of the inboard side row in a severe corrosive environment. It is an object of the present invention to provide a wheel bearing device in which durability can be ensured by reduction and the axial dimension is not increased.
この発明の車輪用軸受装置は、ハブ輪の外周に、列毎に個別の2列の内輪を圧入状態に嵌合させた内方部材と、この内方部材の上記各内輪の転走面に対向する2列の転走面を有する外方部材と、これら内外の部材の転走面間に介在した転動体とを備え、車体に対して車輪を回転自在に支持する車輪用軸受装置において、上記ハブ輪の軸部の外径面および上記各内輪の内径面が円筒面であって、両列の内輪の内径面の内径を互いに異ならせ、またはハブ輪の軸部における各内輪嵌合面部分の外径を互いに異ならせることで、後述のハブ輪インボード側端の加締部の未形成状態における上記各内輪のハブ輪に対する締代につき、アウトボード側の内輪の締代の方がインボード側の内輪の締代よりも大きいものとしたことを特徴とする。
この構成によると、両列の内輪の締代に差をつけ、アウトボード側の内輪の締代の方がインボード側の内輪の締代よりも大きいものとしたため、クリープ発生条件の厳しいアウトボード側列の内輪では、大きな締代によってクリープの発生を防止できる。また、著しい腐食環境下にあるインボード側列の内輪では、締代を小さくすることによってフープ応力の発生を軽減でき、フープ応力、および腐食に伴う強度低下による内輪の耐久性低下が防止できる。また、従来例のように、アウトボード側の内輪の軸方向寸法を大きくしないので、軸受装置の軸方向寸法が大きくなることもない。
The wheel bearing device of the present invention has an inner member in which two rows of inner rings are fitted in a press-fit state on the outer periphery of the hub wheel, and a rolling surface of each inner ring of the inner member. an outer member having two opposite rows of rolling surfaces, and a rolling element interposed between the rolling surfaces of the inner and outer members, Te wheel bearing apparatus odor for rotatably supporting a wheel relative to a vehicle body The outer diameter surface of the shaft portion of the hub wheel and the inner diameter surface of each inner ring are cylindrical surfaces, and the inner diameter surfaces of the inner rings of both rows are made different from each other, or each inner ring is fitted to the shaft portion of the hub wheel. by varying the outer diameter of the face portion to each other, every fastening margin with respect to the upper SL wheel hub of each inner ring in an unformed state of the crimp portion of the hub wheel inboard end of the later, the outboard side of the inner ring of the fastening margin This is characterized in that it is larger than the tightening allowance of the inner ring on the inboard side.
According to this configuration, the tightening allowance of the inner rings in both rows is made different, and the tightening allowance of the inner ring on the outboard side is larger than the tightening allowance of the inner ring on the inboard side. In the inner ring of the side row, generation of creep can be prevented by a large tightening allowance. Further, the inner ring of the inboard row under significant corrosive environment, by the reducing the tightening margin can reduce the occurrence of hoop stress, hoop stress, and the inner ring of the durability reduction due the decrease in strength due to corrosion prevention it can. Further, unlike the conventional example, since the axial dimension of the inner ring on the outboard side is not increased, the axial dimension of the bearing device is not increased.
上記ハブ輪のインボード側端の外周に突出する加締部を設け、この加締部でインボード側の内輪の幅面を押し付けることにより、ハブ輪に嵌合した2列の内輪を、ハブ輪の外径面に設けられた段差面と上記加締部との間で軸方向に締め付けたものとする。
この構成のように加締部で内輪を軸方向に固定するようにした場合、加締部に近いインボード側列の内輪は、加締めによるハブ輪軸部の拡径効果でクリープがより発生し難くなる。そのため、2列の内輪の締代に差を付けたことによるアウトボード側列の内輪のクリープ発生防止と、インボード側列の内輪のフープ応力の発生の軽減による耐久性確保の効果がより一層効果的となる。
A caulking portion that protrudes from the outer periphery of the inboard side end of the hub wheel is provided, and by pressing the width surface of the inner ring on the inboard side with the caulking portion, the two rows of inner rings fitted to the hub wheel are connected to the hub wheel. and a stepped surface provided on the outer surface and the crimping portion as that clamped axially between.
When the inner ring is fixed in the axial direction by the crimping portion as in this configuration, the inner ring in the inboard side row near the crimping portion is more likely to creep due to the diameter expansion effect of the hub ring shaft portion due to the crimping. It becomes difficult. Therefore, the effect of securing the durability by reducing the occurrence of hoop stress of the inner ring of the inboard side row and the prevention of creep generation of the inner ring of the inboard side row by making a difference in the tightening allowance of the two rows of inner rings is further enhanced. Become effective.
この発明において、上記転動体が円すいころであり、上記各転走面が円すい面であっても良い。円すいころ軸受タイプの車輪用軸受装置は、荷重条件の厳しいトラックや4輪駆動車等で使用されることが多く、強度の余裕を持たせることが難しい。そのため、この発明における両列の内輪の締代に差をつけたことによるアウトボード側のクリープ発生防止とインボード側のフープ応力の発生軽減の効果がより効果的に発揮される。 In this invention, the rolling element may be a tapered roller, and each rolling surface may be a tapered surface. Tapered roller bearing type wheel bearing devices are often used in trucks, four-wheel drive vehicles, and the like with severe load conditions, and it is difficult to provide sufficient strength. Therefore, the effect of preventing the occurrence of creep on the outboard side and reducing the occurrence of hoop stress on the inboard side due to the difference in the tightening allowances of the inner rings of both rows in the present invention is more effectively exhibited.
この発明の車輪用軸受装置は、ハブ輪の外周に、列毎に個別の2列の内輪を圧入状態に嵌合させた車輪用軸受装置において、上記ハブ輪の軸部の外径面および上記各内輪の内径面が円筒面であって、両列の内輪の内径面の内径を互いに異ならせ、またはハブ輪の軸部における各内輪嵌合面部分の外径を互いに異ならせることで、ハブ輪インボード側端の加締部の未形成状態における上記各内輪のハブ輪に対する締代に差をつけ、アウトボード側の内輪の締代の方がインボード側の内輪の締代よりも大きいものとし、ハブ輪のインボード側端の外周に突出する加締部を設け、この加締部でインボード側の内輪の幅面を押し付けることにより、ハブ輪に嵌合した2列の内輪を、ハブ輪の外径面に設けられた段差面と上記加締部との間で軸方向に締め付けたため、クリープ発生条件の厳しいアウトボード側列の内輪ではクリープ発生を防止でき、かつ著しい腐食環境下にあるインボード側列の内輪ではフープ応力の発生の軽減による耐久性確保が図れる。また、内輪の軸方向寸法を大きくする必要がなく、軸受装置の軸方向寸法が大きくなることもない。
Wheel support bearing assembly of the present invention, the outer periphery of the hub, the inner ring of the respective two rows for each column Te fitted so the wheel support bearing assembly smell pressed state, and the outer diameter surface of the shaft portion of the hub wheel The inner diameter surface of each inner ring is a cylindrical surface, and the inner diameter surfaces of the inner rings in both rows are different from each other, or the outer diameters of the inner ring fitting surface portions in the shaft portion of the hub wheel are different from each other, with a difference in the tightening margin with respect to the upper SL wheel hub of each inner ring in an unformed state of the crimp portion of the hub wheel inboard end, towards the fastening margin of the inner ring of the outboard side than the fastening margin of the inner ring of the
この発明の参考提案例を図1と共に説明する。この参考提案例の車輪用軸受装置は、複列の円すいころ軸受形式の軸受装置となるものであって、第2.5世代型に分類されるものである。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外側寄りとなる側をアウトボード側と言い、車両の中央寄りとなる側をインボード側と呼ぶ。図1では、左側がアウトボード側、右側がインボード側となる。 A reference proposal example of the present invention will be described with reference to FIG. The wheel bearing device of this reference proposal example is a double row tapered roller bearing type bearing device, and is classified into the 2.5th generation type. 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. In FIG. 1, the left side is the outboard side and the right side is the inboard side.
この車輪用軸受装置は、駆動輪の支持に適用した例であって、内周に2列の転走面1aを有する外方部材1と、これら転走面1aにそれぞれ対向する転走面2aを有する内方部材2と、これら2列の転走面1a,2a間に介在した2列の転動体3とを備える。転動体3は円すいころからなり、各列毎に保持器7で保持されている。内外の部材2,1の転走面2a,1aは円すい面である。内外の部材2,1間に形成される環状空間の両端は一対のシール手段10,11で密封されている。
This wheel bearing device is an example applied to support of a drive wheel, and has an
外方部材1は固定側の部材となるものであって、外周に車体取付フランジ1bを有する一体の部材である。外方部材1は、インボード側端の外周が懸架装置のナックル21の取付孔に嵌合し、車体取付フランジ1bに設けられたボルト孔22を貫通するボルト23によってナックル21に固定されている。
The
内方部材2は回転側の部材となるものであって、外周のアウトボード側端に車輪取付フランジ4aを有するハブ輪4と、このハブ輪4の外周に軸方向に並べてそれぞれ圧入状態に嵌合させた2列の個々の内輪5,6とを有する。これら2列の内輪5,6の外周には、上記各列の転走面2aが形成されている。ハブ輪4の車輪取付フランジ4aは、複数のボルト圧入孔24が設けられ、各孔24に圧入されたボルト25により、車輪(図示せず)取付けられる。
The
ハブ輪4の内周孔26には、等速ジョイント26の外輪27のステム部27aが挿入され、上記内径孔26の内面およびステム部27の外周に設けられたスプライン溝によりスプライン結合される。ステム部27aの先端には雄ねじ部27aaが設けられ、ナット28が螺合している。ナット28は、ハブ輪4のアウトボード側面における内径孔26の周縁に係合しており、ナット28を締め付けることにより、等速ジョイント外輪27の軸方向面27bが内輪6の幅面を軸方向に押し付ける。これにより、両列の内輪5,6が、ハブ輪4の段差面4bと等速ジョイント外輪27の上記軸方向面27bとの間で軸方向に締め付け固定される。上記段差面4bは、ハブ輪4の車輪取付フランジ4aの付近で、インボード側が小径となる面として形成されている。
The
上記2列の内輪5,6のハブ輪4に対する締代については、互いに差がつけられ、アウトボード側列の内輪5の締代の方が、インボード側列の内輪6の締代よりも大きくされている。この締代の違いは、例えば、両列の内輪5,6の内径面に差を持たせることで生じさせている。なお、ハブ輪4の軸部における各内輪嵌合面部分の外径を異ならせることにより、上記締代の差を付けるようにしても良い。
The tightening allowances of the two rows of
上記構成の車輪用軸受装置によると、両列の内輪5,6の締代に差をつけ、アウトボード側の内輪5の締代の方がインボード側の内輪6の締代よりも大きいものとしたため、クリープ発生条件の厳しいアウトボード側列の内輪5では、大きな締代によってクリープの発生を防止できる。また、著しい腐食環境下にあるインボード側列の内輪6では、締代を小さくすることによりってフープ応力の発生を軽減でき、フープ応力、および腐食に伴う強度低下による内輪6の耐久性低下が防止できる。また、従来例のように、アウトボード側の内輪の軸方向寸法を大きくしないので、軸受装置の軸方向寸法が大きくなることもない。
According to the wheel bearing device having the above configuration, the tightening allowance of the
なお、上記参考提案例では、ナット28の締め付けにより、両列の内輪5,6が、ハブ輪4の段差面4bと等速ジョイント外輪27の軸方向面27bとの間で軸方向に締め付け固定されるようにしたが、図2に示すように、ハブ輪4に設けた加締部4cで上記軸方向の締め付け固定を行うようにしても良い。すなわち、ハブ輪4のインボード側端に、軸方向に突出する円筒状部分を設けて外径側へ揺動加締で加締めることにより、上記加締部4cを形成する。この加締部4cをさらに軸方向への加締めることによって、内輪6の幅面を押し付け、両列の内輪5,6を、ハブ輪4の上記段差面4bと加締部4cとの間で軸方向に締め付ける。
この構成のように加締部4cで内輪5,6を軸方向に固定するようにした場合、加締部に近いインボード側列の内輪6は、加締めによるハブ輪軸部の拡径効果でクリープがより発生し難くなる。そのため、2列の内輪5,6の締代に差を付けたことによるアウトボード側列の内輪5のクリープ発生防止と、インボード側列の内輪6のフープ応力の発生の軽減による耐久性確保の効果がより一層効果的となる。

この構成の場合も、2列の内輪5,6をハブ輪4の加締部4cで軸方向に締めつける構成としたため、アウトボード側列の内輪5のクリープ発生防止と、インボード側列の内輪6のフープ応力の発生軽減による耐久性確保の効果がより一層効果的なものとなる。
