上記のように、ホイールベアリングには、センサロータ4がシールとは別に組 付けられており、センサロータ4は、焼結金属でできており、比較的重量が大で ある。また、半径方向の寸法も大であるであり、省スペース、軽量化という点か ら不適当である。 As described above, the sensor rotor 4 is attached to the wheel bearing separately from the seal. The sensor rotor 4 is made of sintered metal and is relatively heavy. Also, the radial dimension is large, which is not suitable from the viewpoint of space saving and weight reduction.
【0004】[0004]
この考案に係わる自動車のホイールベアリング装置は、上記の課題を解決すべ くなされたもので、半径方向に延び、ホイールに取りつけられるフランジ部を外 側軌道輪または内側軌道輪のいずれか一方に一体に形成し、他方の軌道輪は車体 に取りつけられ、内外軌道輪間に多数の転動体が回転自在に組み込まれた転がり 軸受を備え、さらにホイールに取りつけられた軌道輪に設けられた回転数計測用 のセンサロータと、該センサロータに対応して車体側に取りつけられたセンサと を具備する自動車のホイールベアリング装置において、外側軌道輪の内周側端に 圧入され内端縁が内側軌道輪の外径面に向けて延びるシール外環と、該シール外 環の内端縁に固着された密封版と、その外周面が密封版の内周リップと摺接し内 側軌道輪の外周端縁に嵌着されたシール内環と、ホイールに取りつけられたシー ル環の一側面に多数の打ち抜き部を等間隔に配設してセンサ用ロータを形成し、 該センサロータに対峙してセンサを配置したものである。 The wheel bearing device for an automobile according to the present invention has been made to solve the above-mentioned problems.

この考案では、シール外環またはシール内環に多数の打ち抜き穴または切り欠 けを等間隔に配置し、シールのいずれかの環にセンサロータをもうけたのである から、シールは軸受の回転中に密封作用を行うと共に、センサロータの回転速度 に比例した周波数と電圧を発生し、軸受の回転数が検出される。 In this invention, a large number of punched holes or notches are arranged at equal intervals in the outer ring of the seal or the inner ring of the seal, and the sensor rotor is provided in either ring of the seal.

【0006】[0006]
次に、この考案の実施例を図面について説明する。図1はこの考案の実施例に 用いられた軸受の要部を示し、ホイールを取りつけるフランジを一体に設けた外 側軌道輪1と内側軌道輪2との間にボール3が回転自在に介装される。外側軌道 輪1の内周側端14に鋼板にプレス加工して成形されたシール外環15が圧入さ れ、内側軌道輪2に向けて延びる内端縁15aにゴム製の密封板16が焼き付け られている。シール外環15は、図2に示すように外側軌道輪1の端面18に沿 って径方向外方に延びるフランジ18が形成され、該フランジに円周方向の幅W が一定である矩形状の打ち抜き穴19が複数個、円周方向に等間隔Hに配置され 、センサロータ4が形成される。内側軌道輪2の外周面には20には断面L形の シール内環21が嵌着されていおり、密封板16のリップ22a,22b,22 cが該内環21の外周面に摺接する。 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a main part of a bearing used in an embodiment of the present invention, in which a ball 3 is rotatably interposed between an outer race ring 1 and an inner race ring 2 which are integrally provided with a flange for mounting a wheel. To be done. A seal outer ring 15 formed by pressing a steel plate is press-fitted into the inner end 14 of the outer race ring 1, and a rubber sealing plate 16 is baked onto the inner end edge 15a extending toward the inner race ring 2. Has been. As shown in FIG. 2, the outer seal ring 15 is formed with a flange 18 that extends radially outward along the end surface 18 of the outer race 1, and the flange 18 has a rectangular shape with a constant circumferential width W 1. A plurality of punched holes 19 are arranged at equal intervals H in the circumferential direction to form the sensor rotor 4. A seal inner ring 21 having an L-shaped cross section is fitted on the outer peripheral surface of the inner race ring 2 so that the lips 22a, 22b, 22c of the sealing plate 16 are in sliding contact with the outer peripheral surface of the inner ring 21.
【0007】 図示しない本体側にはこの打ち抜き穴19に近接して対峙させてセンサ5が設 けられている。このセンサは可変リアクタンス型であり、磁石による磁界とその 先のポールピースとコイルによって構成され、信号を発生するコイルは、ポール ピースの周りに巻かれ、磁石によって作られている磁界を打ち抜き穴と穴のない 部分がカットするように働く。このために、当該部分は回転速度に比例した周波 数と電圧が発生する。A sensor 5 is provided on the main body side (not shown) so as to face the punched hole 19 and face it. This sensor is a variable reactance type, which is composed of a magnetic field from a magnet and a pole piece and a coil in front of it, and a coil that generates a signal is wound around the pole piece and punches out the magnetic field created by the magnet. It works like cutting the part without holes. For this reason, a frequency and voltage proportional to the rotation speed are generated in this portion.
【0008】 図3に示すのは打ち抜き穴に変えて切り欠け19aとすることができる。また 、打ち抜き部はプレス成形により製造することができる。このため、打ち抜き穴 や切り欠けの形状は矩形の他、円形、長円形など適宜の形状を選択実施すること ができることはいうまでもない。In FIG. 3, a notch 19a can be used instead of the punched hole. Further, the punched portion can be manufactured by press molding. For this reason, it goes without saying that the punched hole and the notch can be formed in a suitable shape such as a circle or an oval in addition to the rectangle.
【0009】 図4に示す実施例は、図1の場合のシール外環15が、さらに外側軌道輪1の 外周面23に沿って折り曲げらる。該折り曲げ部24は外側軌道輪1に対して間 隙を介して対向していると共に、多数の打ち抜き穴19を設け、センサ5をラジ アル方向から打ち抜き穴19に対峙させている。このため、折り曲げ部に設けら れた打ち抜き穴19近傍には金属物体が存在しないために検出能力が向上する。In the embodiment shown in FIG. 4, the seal outer ring 15 in the case of FIG. 1 is further bent along the outer peripheral surface 23 of the outer race ring 1. The bent portion 24 is opposed to the outer race ring 1 with a gap, and is provided with a large number of punched holes 19 so that the sensor 5 faces the punched holes 19 in the radial direction. Therefore, the metal object does not exist in the vicinity of the punched hole 19 provided in the bent portion, so that the detection capability is improved.
【0010】 図5に示す実施例は、内側軌道輪2に嵌着された断面L字形のシール内環21 の外側軌道輪1の端面17側に向けて延びた外周縁25に打ち抜き穴19が設け られたものである。この場合、内側軌道輪2には、図示しないがホイールを取り 付けるフランジ部が内側軌道輪2に一体に構成されている。このために、内側軌 道輪2がホイールと共に回転する構造であり、上記の打ち抜き穴19を設けた部 分はセンサロータを構成するものである。In the embodiment shown in FIG. 5, a punching hole 19 is formed in an outer peripheral edge 25 of a seal inner ring 21 having an L-shaped cross section fitted to the inner race ring 2 and extending toward the end face 17 side of the outer race ring 1. It is provided. In this case, a flange portion (not shown) for mounting the wheel is integrally formed on the inner race ring 2. For this reason, the inner track wheel 2 is structured to rotate together with the wheel, and the portion provided with the punched hole 19 constitutes a sensor rotor.
【0011】 図6に示すのは、図5の場合と同様に内側軌道輪2が回転するタイプの軸受で あって、シール内環21の外周縁が外側軌道輪1の端面17の近傍から軸方向外 方に折り曲がってフランジ部26が形成され、該フランジ部に打ち抜き穴19が 形成されており、該打ち抜き穴の近傍にセンサ5をラジアル方向に配置したもの である。さらに、図7に示すものは、図6の打ち抜き穴19に代えるに切り欠け 19aを設けたものである。図6,図7の実施例も打ち抜き穴19または切り欠 け19aの近傍に金属物体が存在しないので、検出精度が向上する。FIG. 6 shows a bearing in which the inner race 2 rotates, as in the case of FIG. 5, in which the outer peripheral edge of the seal inner ring 21 extends from the vicinity of the end surface 17 of the outer race 1 to the shaft. A flange portion 26 is formed by bending outward in the direction, a punching hole 19 is formed in the flange portion, and the sensor 5 is arranged in the radial direction near the punching hole. Further, the one shown in FIG. 7 has a notch 19a in place of the punched hole 19 in FIG. In the embodiment shown in FIGS. 6 and 7, the metal object does not exist near the punched hole 19 or the notch 19a, so that the detection accuracy is improved.
【0012】[0012]
この考案は、上記のように外側軌道輪の内周側端に圧入され内端縁が内側軌道 輪の外周面に向けて延びるシール外環と、該シール外環の内端縁に固着された密 封版と、その外周面が密封板の内周リップと摺接し内側軌道輪の外周端縁に嵌着 されたシール内環と、シール環の一側面に多数の打ち抜き部を等間隔に配設して センサロータを形成したので、センサロータは鋼板よりプレス成形することによ り製造可能となり、極めて軽量かつ安価となった。また、シールの外環または内 環とセンサロータを一体化できるので、従来品のように内側軌道輪または外側軌 道輪にシール環と別体のセンサロータを設ける必要がなく、省スペースの点から 優れた効果がある。またセンサロータに焼結金属を用いることもなく、軽量化の 他にコスト低減にも寄与するところが大である。 According to the invention, as described above, the outer seal ring is press-fitted to the inner peripheral side end of the outer race ring and the inner end edge extends toward the outer peripheral surface of the inner race ring, and the seal outer ring is fixed to the inner end edge of the seal outer ring. The sealing plate, the seal inner ring whose outer peripheral surface is in sliding contact with the inner peripheral lip of the sealing plate and is fitted to the outer peripheral edge of the inner race, and a large number of punched parts at equal intervals on one side of the seal ring. Since the sensor rotor was installed to form the sensor rotor, the sensor rotor can be manufactured by press forming from a steel plate, which is extremely lightweight and inexpensive. Also, since the sensor rotor can be integrated with the outer ring or inner ring of the seal, it is not necessary to provide a sensor rotor separately from the seal ring on the inner raceway ring or outer raceway wheel as in the conventional product, which saves space. It has an excellent effect. Moreover, without using sintered metal for the sensor rotor, it contributes not only to weight reduction but also to cost reduction.
