Description

【０００１】
【発明の属する技術分野】
本発明は、ハブ軸受に取付けた送信器からの車輪速度信号を確実に受信器に伝送することができる車輪速度信号用送受信装置に関する。
【０００２】
【従来の技術】
例えば、アンチロックブレーキ装置においては、ハブ軸受に取付けた回転センサーにより検出した車輪回転速度の信号を、車体内に設けた制御装置により処理し、車輪のブレーキを緩めて、操舵安定性を確保している。
【０００３】
特開２００１−１５１０９０号公報では、回転センサーからの車輪速度信号を、ワイヤレス伝送手段により、ハブ軸受に取付けた送信器から送信して、タイヤハウスに取付けた受信器により受信している。
【０００４】
これにより、車輪支持部と車体の間で信号送信用の電線が外部に露出しないため、石跳ねやタイヤハウス内の雪の凍結等により、電線が断線する虞れがなく、また、信号送信用の電線を廃止できるため、非常に煩雑な配線取付作業も不要となり、作業工数を大幅に削減でき、製造コストを低減できるといった利点がある。
【０００５】
【発明が解決しようとする課題】
上記公報では、ハブ軸受に取付けた送信器と、タイヤハウスに取付けた受信器との間で、電波、超音波、赤外線等により車輪速度信号を伝送している。
【０００６】
しかしながら、例えば、電波により信号を伝送する場合、ハブ軸受の周囲にある金属製の車体側部品、例えば、ブレーキロータ、そのバッキングプレート、及びナックルにより、電波は、電磁シールドされる虞れがあり、これらの車体側部品の外周囲に位置するタイヤハウスの受信器には、必ずしも十分に到達しないといった問題がある。
【０００７】
本発明は、上述したような事情に鑑みてなされたものであって、ハブ軸受に取付けた送信器からの車輪速度信号を確実に受信器に伝送することができる車輪速度信号用送受信装置を提供することにある。
【０００８】
【課題を解決するための手段】
上記の目的を達成するため、本発明の請求項１に係る車輪速度信号用送受信装置は、走行時に回転し、車幅方向外側に形成した第１のフランジに車輪を固定する回転輪と、外周面に形成した第２のフランジがナックルにねじ止め固定される静止輪とからなるハブ軸受に取付けた送信器からの車輪速度信号を受信器に伝送する車輪速度信号用送受信装置において、
金属製の部品であるブレーキロータ、バッキングプレート及びハブ軸受により囲まれた第１伝送空間内に、前記送信器を露出しながら、ハブ軸受の静止輪に取付けてあり、
この第１伝送空間内に、前記受信器を露出しながら、金属製の部品であるバッキングプレートに取付けたことを特徴とする。
【００１０】
このように、請求項１によれば、送信器も受信器も、電磁シールドされることなく電波の伝送が十分に可能である第１又は第２伝送空間内に露出してある。従って、送信器から発信された電波は、第１又は第２伝送空間内を電磁シールドされることなく伝送されて、受信器により確実に受信される。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態に係る車輪速度信号用送受信装置を図面を参照しつつ説明する。
【００１４】
（実施の形態：請求項１に対応）
図１は、本発明の実施の形態に係る車輪速度信号用送受信装置を備えた車両のハブ取付部の断面図である。
【００１５】
車軸１に、ハブ２が固定してあり、このハブ２の内端側の外周面に、ハブ軸受の内輪部材３が設けてあり、ハブ２と内輪部材３の外径側には、外輪部材４（ハブ軸受の静止側）が設けてある。ハブ２と内輪部材３の外周面と、外輪部材４の内周面との間には、複数列の軸受を構成する転動体５が介装してある。
【００１６】
ハブ２には、鋳鉄製のブレーキロータ６が取付けてあり、外輪部材４には、ブレーキロータ６に対向して、鋼板製のバッキングプレート７が取付けてあり、外輪部材４には、鋳鉄製のナックル８の下端部が取付けてある。
【００１７】
ハブ軸受の内輪部材３の外周面には、ゴム磁石製のエンコーダ９が焼付固定してあり、ハブ軸受の外輪部材４には、このエンコーダ９に対向して、車輪速度用の検出センサー１０が取付けてある。本実施の形態では、この検出センサー１０は、信号電波伝送用の送信器と一体的に樹脂モールドされている。
【００１８】
本実施の形態では、金属製の部品であるブレーキロータ６、バッキングプレート７及びハブ軸受の外輪部材４により囲まれた第１伝送空間Ｘ内に、検出センサー付き送信器１０が露出しながら、ハブ軸受の外輪部材４に取付けてある。
【００１９】
この第１伝送空間Ｘ内に、受信器１１が露出しながら、金属製の部品であるバッキングプレート７に取付けてある。なお、受信器１１は、第１伝送空間Ｘに露出していれば（例えばプレート７に孔を形成して）、ナックル８に取付けてあってもよい。なお、この例では送信器の１部は樹脂に埋込まれているが、ハブ軸受を構成する金属部材の外周包絡線の外に配置しているので実質露出していることになる。
【００２０】
このように、本実施の形態によれば、検出センサー付き送信器１０も受信器１１も、電磁シールドされることなく電波の伝送が十分に可能である第１伝送空間Ｘ内に露出してある。従って、ハブ軸受の外輪部材４に取付けた検出センサー付き送信器１０から発信された電波は、第１伝送空間Ｘ内を電磁シールドされることなく伝送されて、バッキングプレート７に取付けた受信器１１により確実に受信される。
【００２１】
また、バッキングプレート７に取付けた受信器１１からは、ナックル８に沿って配線１２が延在してあり、車体内の制御装置（図示略）に連結してある。これにより、伝送した車輪速度信号は、例えば、アンチロックブレーキ装置の制御装置により処理されて操舵安定性が確保されている。

【００２４】
また、金属製の部品であるナックル８とハブ軸受により囲まれた第２伝送空間Ｙ内に、送信器１３（センサーユニット）が露出しながら、ハブ軸受の外輪部材４の車幅方向内側に取付けてあり、この第２伝送空間Ｙ内に、受信器１１が露出しながら、金属製の部品であるナックル８に取付けてある。
【００２５】
このように、本第 1 参考例によれば、送信器１３（センサーユニット）も受信器１２も、電磁シールドされることなく電波の伝送が十分に可能である第２伝送空間Ｙ内に露出してある。従って、送信器１３（センサーユニット）から発信された電波は、第２伝送空間Ｙ内を電磁シールドされることなく伝送されて、受信器１２により確実に受信される。なお、本実施例では金属製カバーに車輪速度用検出センサーと送信器を一体に樹脂モールドしているが送信器は金属製カバーの外側（図２にて金属製カバーの円輪面の右側）に配置しているので電磁シールドされない所に配置されている。本例も送信部は樹脂に埋込まれているが磁気的には空間Ｙ内に露出している

【００３０】
なお、非金属製にする部品が本第２参考例のようにナックル８である場合には、受信器の取付位置は、例えば、タイヤハウスの内側である。また、非金属製にする部品は、ナックル８に限らず、ブレーキロータ６、バッキングプレート７、及び車体フロアー（図示略）の少なくとも１個の部品であり、車体フロアーを非金属製にした場合、受信器は、車室内に配置してもよく、配線工数を大幅に軽減できる。

For example, in an anti-lock brake device, a wheel rotation speed signal detected by a rotation sensor attached to a hub bearing is processed by a control device provided in the vehicle body, and the wheel brake is released to ensure steering stability. ing.
[0003]
In Japanese Patent Laid-Open No. 2001-151090, a wheel speed signal from a rotation sensor is transmitted from a transmitter attached to a hub bearing by wireless transmission means and received by a receiver attached to a tire house.
[0004]
As a result, the signal transmission wire is not exposed to the outside between the wheel support part and the vehicle body, so there is no risk of the wire breaking due to rock jumping or freezing of snow in the tire house. Therefore, there is an advantage that a very complicated wiring installation work is not required, the number of work steps can be greatly reduced, and the manufacturing cost can be reduced.
[0005]
[Problems to be solved by the invention]
In the above publication, a wheel speed signal is transmitted by radio waves, ultrasonic waves, infrared rays, or the like between a transmitter attached to a hub bearing and a receiver attached to a tire house.

However, for example, when transmitting a signal by radio waves, the radio wave may be electromagnetically shielded by metal car body parts around the hub bearing, for example, the brake rotor, its backing plate, and knuckle. There is a problem that the tire house receiver located in the outer periphery of the vehicle body side parts does not always reach the receiver.
[0007]
The present invention has been made in view of the circumstances as described above, and provides a wheel speed signal transmitting / receiving device capable of reliably transmitting a wheel speed signal from a transmitter attached to a hub bearing to a receiver. There is to do.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a wheel speed signal transmitting / receiving device according to claim 1 of the present invention is a rotating wheel that rotates during traveling and fixes a wheel to a first flange formed on the outer side in the vehicle width direction, and an outer periphery. In a wheel speed signal transmitting / receiving device for transmitting a wheel speed signal from a transmitter attached to a hub bearing formed of a stationary wheel screwed and fixed to a knuckle to a second flange formed on a surface to a receiver,
The transmitter is exposed to the stationary ring of the hub bearing in the first transmission space surrounded by the brake rotor, the backing plate and the hub bearing, which are metal parts,
The receiver is attached to a backing plate, which is a metal part, while exposing the receiver in the first transmission space.
[0010]
Thus , according to the first aspect, both the transmitter and the receiver are exposed in the first or second transmission space in which radio waves can be sufficiently transmitted without being electromagnetically shielded. Therefore, the radio wave transmitted from the transmitter is transmitted without being electromagnetically shielded in the first or second transmission space, and is reliably received by the receiver.
[0013]
DETAILED DESCRIPTION OF THE INVENTION

In the first transmission space X, the receiver 11 is exposed and attached to a backing plate 7 which is a metal part. The receiver 11 may be attached to the knuckle 8 as long as it is exposed to the first transmission space X (for example, a hole is formed in the plate 7). In this example, a part of the transmitter is embedded in the resin, but is substantially exposed because it is disposed outside the outer envelope of the metal member constituting the hub bearing.
[0020]
As described above, according to the present embodiment, both the transmitter 10 with the detection sensor and the receiver 11 are exposed in the first transmission space X that can sufficiently transmit radio waves without being electromagnetically shielded. .

[0021]
Further, from the receiver 11 attached to the backing plate 7, a wiring 12 extends along the knuckle 8, and is connected to a control device (not shown) in the vehicle body. Thereby, the transmitted wheel speed signal is processed by, for example, a control device of the anti-lock brake device to ensure steering stability.
[0022]
(The first reference example)
FIG. 2 is a cross-sectional view of a hub mounting portion of a vehicle provided with a wheel speed signal transmitting / receiving device according to a first reference example of the present invention.
[0023]
In the first reference example , a sensor unit 13 in which an annular passive type detection sensor, a rectifier circuit, and a transmitter are integrally formed is provided inside the hub bearing in the vehicle width direction.

Therefore, the radio wave transmitted from the transmitter 10 with the detection sensor passes through the third transmission space Z, is transmitted through the non-metallic backing plate 7, and is reliably received by the receiver (not shown). Is done.
[0035]
Also in this case, when the part made of non-metal is the backing plate 7 as in the third reference example , the mounting position of the receiver is, for example, the inside of the tire house. The non-metal parts are not limited to the backing plate 7, but are at least one part of the brake rotor 6, the knuckle 8, and the vehicle body floor (not shown).
