Description

この発明は、アンチロックブレーキシステム(以下、単にABSと称する。)用のセンサとそのセンサに対向したパルサリングを備えた軸受装置に関し、特にパルサリングの形状に関するものである。   The present invention relates to a bearing device provided with a sensor for an antilock brake system (hereinafter simply referred to as ABS) and a pulsar ring opposed to the sensor, and particularly relates to the shape of the pulsar ring.

ABS用のセンサとこれに対向したパルサリングを備えた従来の軸受装置は、図6に示したように、内方部材1a、1bと、これに同軸状態に嵌合された外方部材2と、前記内方部材1a、1bと外方部材2の間に介在された複列の転動体3、3と、前記複列の転動体3、3間において内方部材1aの外径面に嵌合されたパルサリング4と、前記外方部材2にパルサリング4に対向して装着されたセンサ5とにより構成される。通常は特許文献1の第4図に見られるように、パルサリング4の外表面は軸線に平行に形成されるとともに、センサ5は軸線に対し直角方向に装着される。   As shown in FIG. 6, the conventional bearing device having an ABS sensor and a pulsar ring opposed thereto includes inner members 1 a and 1 b, and an outer member 2 fitted coaxially thereto. The double-row rolling elements 3 and 3 interposed between the inner members 1a and 1b and the outer member 2, and the outer-diameter surface of the inner member 1a between the double-row rolling elements 3 and 3 And a sensor 5 mounted on the outer member 2 so as to face the pulsar ring 4. Normally, as seen in FIG. 4 of Patent Document 1, the outer surface of the pulsar ring 4 is formed parallel to the axis, and the sensor 5 is mounted in a direction perpendicular to the axis.

しかし、軸受の小型化に伴う寸法や、ナックルへの取り付け位置の制約から、図6に示したように、センサ5が所定の傾斜角θをもって装着されるとともに、これに対応してパルサリング4も外表面が所定の傾斜角θをもった円錐台形に形成されたものが用いられる(特許文献1の図3参照)。
特許第2988989号公報
However, as shown in FIG. 6, the sensor 5 is mounted with a predetermined inclination angle θ as shown in FIG. An outer surface having a truncated cone shape having a predetermined inclination angle θ is used (see FIG. 3 of Patent Document 1).
Japanese Patent No. 2988889

前記のようにセンサ5を傾斜角θをもって装着することは、軸受の小型化等に有利な構造であるが、センサ5の傾斜角θは軸受の型番ごとに異なることが通常であるので、その角度に対応した傾斜角度をもったパルサリング4が必要になる。その結果、パルサリング4を型番の異なった軸受相互間において共用できないという問題があった。   Mounting the sensor 5 with the inclination angle θ as described above is an advantageous structure for reducing the size of the bearing, but the inclination angle θ of the sensor 5 is usually different for each bearing model number. A pulsar ring 4 having an inclination angle corresponding to the angle is required. As a result, there is a problem that the pulsar ring 4 cannot be shared between bearings of different model numbers.

そこで、この発明はセンサの傾斜角度にかかわらず、単一形状のパルサリングで対応できるようにし、パルサリングの共用化を実現することを課題とする。   SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to make it possible to cope with pulsar ring having a single shape regardless of the inclination angle of the sensor and to realize sharing of pulsar ring.

前記の課題を解決するために、この発明は、図1(a)に示したように、内方部材11a、11bと、これに同軸状態に嵌合された外方部材12と、前記内方部材11a、11bと外方部材12の間に介在された複列の転動体13、13と、前記複列の転動体13、13間において前記内方部材11aの外径面に嵌合されたパルサリング14と、前記パルサリング14に対向して前記外方部材12に装着されたセンサ15とからなる軸受装置において、前記パルサリング14の外表面16の軸方向の断面形状が軸に対する平行部分16a(図1(b)参照)とその平行部分16aに緩やかに連続した円弧部分16bを含む構成としたものである。センサ15の先端面18は円弧状に形成される場合(図1(a)参照)と、外周縁に面取り28が施される場合(図3、図5参照)がある。   In order to solve the above-mentioned problem, as shown in FIG. 1 (a), the present invention includes inner members 11a and 11b, an outer member 12 fitted coaxially thereto, and the inner member. The double-row rolling elements 13 and 13 interposed between the members 11a and 11b and the outer member 12, and the outer-diameter surface of the inner member 11a are fitted between the double-row rolling elements 13 and 13. In a bearing device comprising a pulsar ring 14 and a sensor 15 mounted on the outer member 12 so as to face the pulsar ring 14, the axial cross section of the outer surface 16 of the pulsar ring 14 has a parallel portion 16a (see FIG. 1 (b)) and the arcuate portion 16b that is gently continuous with the parallel portion 16a. The tip surface 18 of the sensor 15 may be formed in an arc shape (see FIG. 1A), or the chamfer 28 may be applied to the outer peripheral edge (see FIGS. 3 and 5).

上記構成の軸受装置は、ハブ22と一体の内方部材11a、11b、該内方部材11a、11bと一体のパルサリング14の回転に伴う磁界の変化がパルサリング14に接近配置されたセンサ15によって検出され、その検出信号が外部の制御ユニットに出力される。センサ15が所定の傾斜角θをもって装着される場合は、センサ15をパルサリング14の円弧部分16bに対向させる(図1(a)参照)。また、センサ15が軸に対して直角(θ=0度)に装着される場合は、その先端面をパルサリング14の平行部分16aに対向させる(図4参照)。   In the bearing device configured as described above, the inner members 11a and 11b integral with the hub 22 and the change in the magnetic field accompanying the rotation of the pulsar ring 14 integral with the inner members 11a and 11b are detected by the sensor 15 disposed close to the pulsar ring 14. The detection signal is output to an external control unit. When the sensor 15 is mounted with a predetermined inclination angle θ, the sensor 15 is opposed to the arc portion 16b of the pulsar ring 14 (see FIG. 1A). Further, when the sensor 15 is mounted at a right angle (θ = 0 degrees) with respect to the axis, the front end surface thereof is opposed to the parallel portion 16a of the pulsar ring 14 (see FIG. 4).

以上のように、この発明の軸受装置は、パルサリング14の外表面16の軸方向の断面形状が軸に対する平行部分16aとその平行部分16aに緩やかに連続した円弧部分16bを含んだ形状を有するものであるから、センサ15が軸に対して所要の角度をもって装着される場合、また直角に装着される場合のいずれにおいても、共通のパルサリング14で対応することができ、型番の異なる軸受装置においてパルサリング14の共用化を図ることができる。   As described above, the bearing device of the present invention has a shape in which the cross-sectional shape in the axial direction of the outer surface 16 of the pulsar ring 14 includes the parallel portion 16a with respect to the shaft and the arc portion 16b that is gently continuous with the parallel portion 16a. Therefore, whether the sensor 15 is mounted at a required angle with respect to the shaft or mounted at a right angle can be handled by the common pulsar ring 14, and the pulsar ring can be used in bearing devices having different model numbers. 14 can be shared.

また、センサ15の先端面18が円弧形状に形成された構成、又は先端面の外周縁に面取り28が施された構成を採用すると、センサ15の先端面外周縁がパルサリング14の円弧部分16bに干渉するおそれを無くすことができる。   Further, when a configuration in which the distal end surface 18 of the sensor 15 is formed in an arc shape or a configuration in which the outer peripheral edge of the distal end surface is chamfered 28 is adopted, the outer peripheral edge of the distal end surface of the sensor 15 becomes an arc portion 16b of the pulsar ring 14. The possibility of interference can be eliminated.

以下、添付図面に基づいてこの発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図1及び図2に示した実施例1の軸受装置21は、車輪のハブ22に組付けられてハブユニットを構成するものであり、軸受装置21の内方部材11a、11bの一方の内方部材11aは、ハブ22の円筒軸部23に直接軌道溝24を形成することにより構成される。他方の内方部材11bは前記の円筒軸部23の先端部外周面に嵌合一体化される。前記内方部材11a、11bとその外径側に回転自在に嵌合された外方部材12の間に玉でなる転動体13、13が介在され、これらの転動体13、13の外側においてシール部材17、17が装着される。なお、転動体13としては、玉に代えて図6のようにコロを使用する場合もある。   The bearing device 21 according to the first embodiment shown in FIGS. 1 and 2 is assembled to a wheel hub 22 to constitute a hub unit. One of the inner members 11a and 11b of the bearing device 21 is inward. The member 11 a is configured by forming a track groove 24 directly in the cylindrical shaft portion 23 of the hub 22. The other inner member 11 b is fitted and integrated with the outer peripheral surface of the tip end portion of the cylindrical shaft portion 23. Rolling elements 13 and 13 made of balls are interposed between the inner members 11a and 11b and an outer member 12 that is rotatably fitted on the outer diameter side, and seals are provided outside the rolling elements 13 and 13. Members 17 and 17 are attached. In addition, as a rolling element 13, it replaces with a ball | bowl and a roller may be used like FIG.

前記2列の転動体13、13の中間部分において、一方の内方部材11a(即ち、円筒軸部23)の外径面にパルサリング14が嵌合固定される。パルサリング14は磁性体で形成され、その外径面に軸方向のセレーション25(図2(a)参照)が形成される。このパルサリング14の軸方向の断面形状(図1(b)参照)において、セレーション25の外表面16の形状は、軸に対する平行部分16aと、その平行部分16aの一端に緩やかに連続した円弧部分16bからなる。平行部分16aに代えて図1(c)に示したような傾斜部分16cを形成する場合もある。   The pulsar ring 14 is fitted and fixed to the outer diameter surface of one inner member 11a (that is, the cylindrical shaft portion 23) in an intermediate portion between the two rows of rolling elements 13 and 13. The pulsar ring 14 is formed of a magnetic material, and an axial serration 25 (see FIG. 2A) is formed on the outer diameter surface thereof. In the cross-sectional shape of the pulsar ring 14 in the axial direction (see FIG. 1B), the shape of the outer surface 16 of the serration 25 includes a parallel part 16a with respect to the axis and an arc part 16b that is gently continuous with one end of the parallel part 16a. Consists of. An inclined portion 16c as shown in FIG. 1C may be formed instead of the parallel portion 16a.

なお、パルサリング14は、図2(b)に示したような多磁極面26を形成した多磁極型のものを使用することもできる。   The pulsar ring 14 may be a multi-pole type having a multi-pole surface 26 as shown in FIG.

一方、外方部材12の軸線と直交する基準線Lに対し一定の傾斜角θをもってセンサ15が外方部材12に装着される。センサ15の先端面18は、前記円弧部分16bと同程度またはそれ以下の大きさの円弧面に形成され、その先端面18が前記パルサリング14の円弧部分16bに接近され、所定のギャップをおいて対向する。センサ15の外径面にパッキン19が装着され、水密を保持するようにしている。   On the other hand, the sensor 15 is attached to the outer member 12 with a constant inclination angle θ with respect to a reference line L orthogonal to the axis of the outer member 12. The tip surface 18 of the sensor 15 is formed as an arc surface having a size equal to or smaller than the arc portion 16b, and the tip surface 18 approaches the arc portion 16b of the pulsar ring 14 with a predetermined gap. opposite. A packing 19 is mounted on the outer diameter surface of the sensor 15 so as to maintain watertightness.

センサ15は、電磁ピックアップコイル方式による、いわゆるパッシブタイプのもののほか、ホールICやMR素子による、いわゆるアクティブタイプのものを用いることができる。   The sensor 15 can be a so-called passive type using an electromagnetic pickup coil system, or a so-called active type using a Hall IC or MR element.

ハブ22と一体の内方部材11a及びパルサリング14が回転することによって生じる磁界の変化がセンサ15において検出され、ケーブル27を経て制御ユニットに出力される。   A change in the magnetic field generated by the rotation of the inner member 11a integrated with the hub 22 and the pulsar ring 14 is detected by the sensor 15 and output to the control unit via the cable 27.

なお、センサ15の先端面18の形状は、図3に示したように平坦面の外周縁に面取り28を施したものであってもよい。   In addition, the shape of the front end surface 18 of the sensor 15 may be obtained by chamfering the outer peripheral edge of a flat surface as shown in FIG.

図4及び図5に示した実施例2の軸受装置21は、センサ15が前記の基準線Lと平行、すなわち傾斜角0で取り付けられる場合である。この場合のパルサリング14は、前記の実施例1の場合と同一形状であり、センサ15の先端面18の中心がパルサリング14の平行部分16aに接近するよう配置される。このように、パルサリング14は、センサ15が傾斜角θを持つ場合(実施例1)にも、また持たない場合(実施例2)にも共通に使用することができる。   The bearing device 21 of the second embodiment shown in FIGS. 4 and 5 is a case where the sensor 15 is mounted in parallel with the reference line L, that is, at an inclination angle of 0. The pulsar ring 14 in this case has the same shape as in the first embodiment, and is arranged so that the center of the tip surface 18 of the sensor 15 approaches the parallel portion 16a of the pulsar ring 14. As described above, the pulsar ring 14 can be commonly used both when the sensor 15 has the inclination angle θ (Example 1) and when the sensor 15 does not have the inclination angle θ (Example 2).

なお、パルサリング14も、実施例1の場合と同様に多磁極型のもの(図2(b)参照)を使用することができ、また、センサ15の先端面18に面取り28を施した構成をとることができる(図5参照)。その他の構成は実施例1と同じであり作用効果も同様である。   The pulsar ring 14 can also be a multi-pole type (see FIG. 2B) as in the first embodiment, and has a configuration in which the tip surface 18 of the sensor 15 is chamfered 28. (See FIG. 5). Other configurations are the same as those of the first embodiment, and the operational effects are also the same.
