Description

本発明は車輪用軸受装置のセンサ付カバー（以下、単にカバーともいう）に関する。さらに詳しくは、車輪の回転速度を検知するためのセンサが取り付けられるカバーにおけるセンサ取付構造に関する。   The present invention relates to a sensor-equipped cover for a wheel bearing device (hereinafter also simply referred to as a cover). More specifically, the present invention relates to a sensor mounting structure in a cover to which a sensor for detecting the rotational speed of a wheel is mounted.

車両においてアンチロックブレーキシステム（ＡＢＳ）やトラクションコントロールシステム（ＴＣＳ）を制御するためには、前記車両の車輪の回転速度を検出する必要がある。このため、前記車輪を車両の懸架装置に対して回転自在に支持する車輪用軸受装置の外輪部材の一端に嵌め込まれたカバーにセンサ部を取り付け、このセンサ部によって前記軸受装置の内輪部材、つまりはこの内輪部材に固定された被検知部により、車輪の回転速度を検知することが行われている。   In order to control an anti-lock brake system (ABS) or a traction control system (TCS) in a vehicle, it is necessary to detect the rotational speed of the wheels of the vehicle. For this reason, a sensor part is attached to a cover fitted to one end of an outer ring member of a wheel bearing device that rotatably supports the wheel with respect to a vehicle suspension, and the inner ring member of the bearing device, i.e. The rotation speed of the wheel is detected by the detected portion fixed to the inner ring member.

前記センサ部は、従来より、カバーとは別体の構造とし、このセンサ部をカバーに形成した通孔に挿入した状態で当該カバーに固定されていたが、近年、センサの位置決めの精度を向上させるとともに、組立コストを低減させるために、図２に示されるように、合成樹脂のモールド成形によって、前記センサ部をカバーと一体にすることが提案されている（例えば、特許文献１参照）。
図２において、金属板で作製されたカバー３１は外輪部材３２の一端の内周面に嵌め込まれており、当該カバー３１に形成された通孔３３において、端子３４を支持するコネクタ３５及びセンサ素子３６からなるセンサ部３７が、合成樹脂のモールド成形により前記カバー３１と一体にされている。 Conventionally, the sensor unit has a separate structure from the cover, and the sensor unit is fixed to the cover in a state where the sensor unit is inserted into a through hole formed in the cover. However, in recent years, the accuracy of sensor positioning has been improved. In order to reduce the assembly cost, it has been proposed to integrate the sensor part with the cover by molding a synthetic resin as shown in FIG. 2 (see, for example, Patent Document 1).
In FIG. 2, a cover 31 made of a metal plate is fitted into an inner peripheral surface of one end of the outer ring member 32, and a connector 35 and a sensor element that support a terminal 34 in a through hole 33 formed in the cover 31. A sensor portion 37 made of 36 is integrated with the cover 31 by molding of synthetic resin.

特開２００１−１９４３７６号公報JP 2001-194376 A

しかしながら、特許文献１に記載されているセンサの取付構造では、カバー３１の内側に位置する合成樹脂部分３８が、容積の割には表面積が小さいブロック状を呈しており、その径方向（図２において上下方向）のサイズは、カバー３１の外側面３１ａに接触するコネクタ３５のフランジ部３５ａよりも小さい。そのため、成形時において樹脂の冷却に時間がかかるので樹脂内部に巣（空洞）が発生し易くなり、充分な強度が得られないことがある。その結果、カバー３１への固定（取付）部分が破損してセンサ部３７がカバー３１から外れてしまうという問題がある。
また、センサ素子３６が埋設されている合成樹脂部分３８の径方向（図２において上下方向）のサイズは、カバー３１の外側面３１ａに位置するコネクタ３５のサイズと略同程度にされており、センサ素子３６への雑音の入力を抑制するコンデンサを前記センサ部３７に設けようとすると、前記合成樹脂部分３８の軸方向（図２において左右方向）の寸法が大きくなり、その分軸受装置全体のサイズが大きくなるため、設計の自由度が低下するという問題もある。 However, in the sensor mounting structure described in Patent Document 1, the synthetic resin portion 38 located inside the cover 31 has a block shape with a small surface area for the volume, and its radial direction (FIG. 2). In the vertical direction) is smaller than the flange portion 35 a of the connector 35 that contacts the outer surface 31 a of the cover 31. For this reason, since it takes time to cool the resin during molding, nests (cavities) are likely to be generated inside the resin, and sufficient strength may not be obtained. As a result, there is a problem that a portion fixed (attached) to the cover 31 is damaged and the sensor unit 37 is detached from the cover 31.
Further, the size in the radial direction (vertical direction in FIG. 2) of the synthetic resin portion 38 in which the sensor element 36 is embedded is substantially the same as the size of the connector 35 located on the outer surface 31a of the cover 31. When the sensor unit 37 is provided with a capacitor that suppresses noise input to the sensor element 36, the dimension of the synthetic resin portion 38 in the axial direction (left-right direction in FIG. 2) increases, and accordingly, the entire bearing device is increased. Since the size increases, there is a problem that the degree of freedom in design is reduced.

本発明は、このような事情に鑑み、巣の発生を抑制してセンサ部のカバーへの取付強度を大きくするとともに、車輪用軸受装置の軸方向の寸法を小さくして設計の自由度を高めることができるカバーを提供することを目的としている。   In view of such circumstances, the present invention increases the attachment strength of the sensor unit to the cover by suppressing the generation of nests, and reduces the axial dimension of the wheel bearing device to increase the degree of freedom in design. The aim is to provide a cover that can.

本発明のカバーは、車輪用軸受装置の外輪部材に取り付けられ、転動体を介して前記外輪部材の内径側に回転自在に配設される内輪部材の回転を検知するセンサ部が設けられ、且つ金属で作製された、車輪用軸受装置のセンサ付カバーであって、
前記センサ部は、前記内輪部材の回転を非接触で磁気的に検出するセンサ素子と、このセンサ素子に電気的に接続される端子を支持するコネクタと、コンデンサとを備えており、
前記センサ部は、合成樹脂のモールド成形によって、前記カバーに形成された通孔部分において当該カバーと一体に形成されており、
前記カバーの内側に位置する合成樹脂部分が、当該カバーの外側面に接触する前記コネクタのフランジ部よりも外側に且つカバー内側面に接触しつつ延びており、且つ
前記コンデンサが前記センサ素子よりも径方向内側に配置されていることを特徴としている。 The cover of the present invention is provided with a sensor unit that is attached to an outer ring member of a wheel bearing device and that detects rotation of an inner ring member that is rotatably disposed on an inner diameter side of the outer ring member via a rolling element, and It is a cover with a sensor of a wheel bearing device made of metal,
The sensor unit includes a sensor element that magnetically detects rotation of the inner ring member in a non-contact manner, a connector that supports a terminal electrically connected to the sensor element, and a capacitor.
The sensor part is formed integrally with the cover at a through-hole part formed in the cover by molding of synthetic resin.
The synthetic resin portion located inside the cover extends outside the flange portion of the connector that contacts the outer side surface of the cover and in contact with the inner side surface of the cover, and the capacitor is more than the sensor element. It is characterized by being arranged radially inside.

本発明のカバーは、カバーの内側に位置する合成樹脂部分が、当該カバーの外側面に接触する前記コネクタのフランジ部よりも外側に且つカバー内側面に接触しつつ延びており、その容積の割には表面積が大きくなっている。しかも熱伝導率の大きな金属製カバーとの接触面積が従来よりも増大しているので、樹脂の冷却速度が速くなり、その結果樹脂内部における巣の発生を抑制することができる。これにより、センサ部のカバーへの取付強度を長期に亘り維持することができる。   In the cover of the present invention, the synthetic resin portion located inside the cover extends outside the flange portion of the connector that contacts the outer side surface of the cover and while contacting the inner side surface of the cover. Has a large surface area. Moreover, since the contact area with the metal cover having a high thermal conductivity is increased as compared with the conventional case, the cooling rate of the resin is increased, and as a result, the formation of nests inside the resin can be suppressed. Thereby, the attachment strength to the cover of a sensor part can be maintained over a long period of time.

また、コンデンサをセンサ素子よりも径方向内側に配置するとともに、カバー内側の合成樹脂部分を径方向に延ばすことで、当該合成樹脂部分の軸方向の寸法を抑えることができ、その分だけ軸受装置の軸方向の寸法を小さくすることができるので、当該軸受装置の設計の自由度を高めることができる。   Further, by disposing the capacitor radially inward of the sensor element and extending the synthetic resin portion inside the cover in the radial direction, the axial dimension of the synthetic resin portion can be suppressed, and the bearing device accordingly. Therefore, the degree of freedom in designing the bearing device can be increased.

本発明のカバーによれば、巣の発生を抑制してセンサ部のカバーへの取付強度を大きくするとともに、車輪用軸受装置の軸方向の寸法を小さくして設計の自由度を高めることができる。   According to the cover of the present invention, the occurrence of nests can be suppressed to increase the mounting strength of the sensor unit to the cover, and the axial dimension of the wheel bearing device can be reduced to increase the degree of freedom in design. .

以下、添付図面に基づいて、本発明のカバーの実施の形態を詳細に説明する。
図１は、本発明の一実施の形態に係るカバーが装着された車輪用軸受装置の断面を示している。前記軸受装置は、車両における従動輪側の車軸用軸受装置であり、車体取付フランジ９を介して車体側に固定されるとともに、その内周面に複列の外輪軌道面１０を有する外輪部材２と、この外輪部材２の内径側において当該外輪部材２と同心に配置されるとともに、その外周面に複列の内輪軌道面１１を有する内輪部材１２と、前記外輪部材２及び内輪部材１２の各軌道面１０、１１間に転動自在に介装された複列の転動体であるボール１３とを備えている。前記内輪部材１２は、ハブ輪１４と、このハブ輪１４の車両インナ側端部外径に嵌合された別体の内輪構成部材１５とで構成されている。ハブ輪１４は、複列のボール１３を介して、前記外輪部材２に回転自在に支持されている。 Hereinafter, embodiments of the cover of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a cross-section of a wheel bearing device equipped with a cover according to an embodiment of the present invention. The bearing device is an axle bearing device on the side of a driven wheel in a vehicle, and is fixed to the vehicle body side via a vehicle body mounting flange 9 and has an outer ring member 2 having double-row outer ring raceway surfaces 10 on its inner peripheral surface. And an inner ring member 12 which is arranged concentrically with the outer ring member 2 on the inner diameter side of the outer ring member 2 and has a double row inner ring raceway surface 11 on the outer circumferential surface thereof, and each of the outer ring member 2 and the inner ring member 12. And a ball 13 which is a double row rolling element interposed between the raceway surfaces 10 and 11 so as to roll freely. The inner ring member 12 includes a hub wheel 14 and a separate inner ring member 15 fitted to the outer diameter of the end of the vehicle inner side of the hub wheel 14. The hub wheel 14 is rotatably supported by the outer ring member 2 via double rows of balls 13.

前記外輪部材２の一端部（車両インナ側端部）の開口は、例えば鉄等の金属をプレス成形することで作製されたカバー１により覆われている。具体的には、有底短円筒形状のカバー１が外輪部材２の端部内周面に嵌め込まれている。前記カバー１に形成された通孔３部分において、一端がセンサ素子６に接続されている端子４を支持するコネクタ５、及び前記センサ素子６に接続されているコンデンサ１６からなるセンサ部７が、合成樹脂のモールド成形により当該カバー１と一体にされている。前記センサ素子６は、内輪構成部材１５の車両インナ側端部の外周面に固定された支持環１７のリング状円輪部１８に設けられた磁石部１９と所定の隙間を隔てて対向するよう、配置されている。   The opening of one end portion (vehicle inner side end portion) of the outer ring member 2 is covered with a cover 1 made by press-molding a metal such as iron. Specifically, a bottomed short cylindrical cover 1 is fitted into the inner peripheral surface of the end portion of the outer ring member 2. In the through hole 3 portion formed in the cover 1, a sensor portion 7 including a connector 5 that supports a terminal 4 having one end connected to the sensor element 6, and a capacitor 16 connected to the sensor element 6, The cover 1 is integrated with the synthetic resin by molding. The sensor element 6 faces the magnet 19 provided on the ring-shaped annular portion 18 of the support ring 17 fixed to the outer peripheral surface of the inner end of the inner ring constituting member 15 with a predetermined gap. Have been placed.

本発明の特徴は、前記センサ素子６、コネクタ５及びコンデンサ１６からなるセンサ部７を合成樹脂のモールド成形により金属製のカバー１と一体化させるに際し、前記カバー１の内側に位置する合成樹脂部分８を、当該カバー１の外側面１ａに接触する前記コネクタ５のフランジ部５ａに相当する範囲よりも外側に且つカバー内側面に接触しつつ延ばすとともに、前記コンデンサ１６を前記センサ素子６よりも径方向内側（軸受装置の軸を基準とした径方向の内側）に配置したことである。これにより、カバー１の内側に位置する合成樹脂部分８の表面積を、その容積の割には大きくすることができる。しかも熱伝導率の大きな金属製カバー１との接触面積が従来よりも増大するとともに、カバー１の内側面であって、その裏面に前記コネクタ５のフランジ部５ａが接触していない部分（図１においてＡで示されるカバー部分の内側面のこと）との接触が可能となるので、樹脂の冷却速度が速くなり、樹脂内部における巣の発生を抑制することができる。その結果、センサ部７のカバー１への取付強度を長期に亘り維持することができるので、センサ部７がカバー１からズレたり、脱落したりするのが防止される。   A feature of the present invention is that a synthetic resin portion located inside the cover 1 when the sensor portion 7 comprising the sensor element 6, the connector 5 and the capacitor 16 is integrated with the metal cover 1 by molding of synthetic resin. 8 extends outside the range corresponding to the flange portion 5 a of the connector 5 that contacts the outer side surface 1 a of the cover 1 and in contact with the inner side surface of the cover, and the capacitor 16 has a diameter larger than that of the sensor element 6. It is arranged in the direction inner side (the inner side in the radial direction with reference to the shaft of the bearing device). Thereby, the surface area of the synthetic resin part 8 located inside the cover 1 can be increased for its volume. In addition, the contact area with the metal cover 1 having a high thermal conductivity is increased as compared to the conventional case, and the inner surface of the cover 1 is a portion where the flange portion 5a of the connector 5 is not in contact with the rear surface (FIG. 1 The inner surface of the cover portion indicated by A) can be contacted, so that the cooling rate of the resin is increased and the formation of nests inside the resin can be suppressed. As a result, the attachment strength of the sensor unit 7 to the cover 1 can be maintained for a long period of time, so that the sensor unit 7 is prevented from being displaced from the cover 1 or falling off.

また、コンデンサ１６をセンサ素子６よりも径方向内側に配置するとともに、カバー１内側の合成樹脂部分８を径方向に延ばすことで、当該合成樹脂部分８の軸方向（車輪用軸受装置の軸方向）の寸法を抑えることができ、その分だけ軸受装置の軸方向の寸法を小さくすることができるので、当該軸受装置の設計の自由度を高めることができる。この軸方向寸法の縮小割合であるが、従来の方法で樹脂による一体化を図った場合の寸法を１とすると、例えば０．４〜０．８程度に縮小することができ、一般的な自動車に使用される車輪用軸受装置の場合、通常２〜９ｍｍ程度寸法を小さくすることができる。   In addition, the capacitor 16 is disposed radially inward of the sensor element 6 and the synthetic resin portion 8 inside the cover 1 is extended in the radial direction, whereby the axial direction of the synthetic resin portion 8 (the axial direction of the wheel bearing device). ) Can be suppressed, and the axial dimension of the bearing device can be reduced by that amount, so that the degree of freedom in designing the bearing device can be increased. This is the reduction ratio of the axial dimension. If the dimension when integrating with resin by the conventional method is 1, it can be reduced to, for example, about 0.4 to 0.8. In the case of the wheel bearing device used in the above, the size can be usually reduced by about 2 to 9 mm.

本実施の形態におけるセンサ部７のカバー１への取付方法であるが、まず、一端にセンサ素子６が接続された端子４を支持するコネクタ５を、そのフランジ部５ａの開口がカバー１の通孔３と対応するように当該カバー１の所定部分に治具で固定する。なお、コンデンサ１６が、前記センサ素子６の内径側に位置するように当該センサ素子６に接続されている。ついで、前記コネクタ５の凹部にセンサ素子６を被覆する合成樹脂部分の一部が入り込むようにインサート成型することにより、カバー１と一体になるようにセンサ部７を当該カバー１に取り付けることができる。この場合、コネクタ５を、円筒体５ｃと、この円筒体５ｃの一端に形成され当該円筒体５ｃの外周面よりも径方向外側に突出している円環状のフランジ部５ａと、前記円筒体５ｃの一端に形成され当該円筒体５ｃの内周面よりも径方向内側に突出している前記フランジ部５ａの内縁部５ｂとで構成し、センサ素子６を被覆する合成樹脂部分８の一部を、コネクタ５の内縁部５ｂを越えて円筒体５ｃに入り込ませて係合部８ａを形成し、前記内縁部５ｂと係合部８ａとを互いに噛み合うかぎ状にすることで、前記コネクタ５、センサ素子６を被覆する合成樹脂部分８及びカバー１を強固に一体化することができる。また、コネクタ５と、センサ素子６を被覆する合成樹脂部分を別体にすることにより、それぞれの部分に必要な強度に合わせて最適な樹脂材料を選定することができる。さらに、コネクタ５とセンサ素子６を被覆する合成樹脂部分が別成型可能で金型の製作が容易になるので、製作コストを削減することができる。   In this embodiment, the sensor unit 7 is attached to the cover 1. First, the connector 5 that supports the terminal 4 to which the sensor element 6 is connected at one end is connected to the cover 5. It fixes to the predetermined part of the said cover 1 with a jig | tool so that it may correspond to the hole 3. FIG. The capacitor 16 is connected to the sensor element 6 so as to be positioned on the inner diameter side of the sensor element 6. Next, the sensor portion 7 can be attached to the cover 1 so as to be integrated with the cover 1 by insert molding so that a part of the synthetic resin portion that covers the sensor element 6 enters the concave portion of the connector 5. . In this case, the connector 5 includes a cylindrical body 5c, an annular flange portion 5a formed at one end of the cylindrical body 5c and projecting radially outward from the outer peripheral surface of the cylindrical body 5c, and the cylindrical body 5c. A portion of the synthetic resin portion 8 that is formed at one end and is formed with an inner edge portion 5b of the flange portion 5a that protrudes radially inward from the inner peripheral surface of the cylindrical body 5c, and covers the sensor element 6, 5 is inserted into the cylindrical body 5c beyond the inner edge portion 5b to form an engaging portion 8a, and the inner edge portion 5b and the engaging portion 8a are engaged with each other to form a hooked shape. Can be firmly integrated with the synthetic resin portion 8 and the cover 1. Further, by making the connector 5 and the synthetic resin portion covering the sensor element 6 separate, it is possible to select an optimal resin material in accordance with the strength required for each portion. Furthermore, since the synthetic resin portion covering the connector 5 and the sensor element 6 can be separately molded and the mold can be easily manufactured, the manufacturing cost can be reduced.

なお、前述した実施の形態では、被検知体として内輪構成部材の端部外周面に設けられた磁石部を用いているが、本発明において、かかる被検知体の種類及び配置、並びにセンサ素子の種類等を含むセンサ部の構成は、特に限定されるものではなく、通常用いられているものを適宜採用することができる。   In the above-described embodiment, the magnet portion provided on the outer peripheral surface of the end portion of the inner ring constituent member is used as the detected body. However, in the present invention, the type and arrangement of the detected body, and the sensor element The configuration of the sensor unit including the type and the like is not particularly limited, and a commonly used one can be appropriately employed.
