Title (EN) ROLLING BEARING UNIT FOR SUPPORTING VEHICLE WHEEL
(FR) UNITÉ PALIER À ROULEMENT PERMETTANT DE PORTER UNE ROUE
(JA) 車輪支持用転がり軸受ユニット
Abstract:
(EN) Provided is a rolling bearing unit for supporting a vehicle wheel, wherein a dimensional increase in the axial dimension accompanying the installation of a power generator and a wireless communication apparatus can be suppressed to a minimum, sufficient power can be supplied to a sensor mounted on a vehicle wheel, and an output signal of the sensor can be wirelessly transmitted to a vehicle body-side electronic apparatus. A hub 17 has an inner recess section 29 on an inner diameter side of an inner section in the axial direction, the inner recess section 29 having, on the inner peripheral surface thereof, a cylindrical fitting surface section 30 which is coaxial with the central axis of the hub 17, and a hollow cylindrical support member 67 is supported and fixed inside the inner recess section 29 in a state in which a cylindrical guide surface section 70 provided on the outer peripheral surface of the support member is fitted into the fitting surface section 30. A rotor 61 serving as an armature is fixed to an axial inner section of the support member 67 to be coaxial with the support member 67, and a wireless communication apparatus 12 is disposed on the inside of the support member 67 in the radial direction. A through-hole 34, in which wiring 57 is disposed, is formed in the bottom surface 31 of the inner recess section 29.
(FR) L'invention concerne une unité palier à roulement destinée à porter une roue de véhicule, une augmentation dimensionnelle dans la dimension axiale accompagnant l'installation d'un générateur d'énergie et d'un appareil de communication sans fil peut être réduite au minimum, une puissance suffisante peut être fournie à un capteur monté sur une roue de véhicule, et un signal de sortie du capteur peut être émis sans fil à un appareil électronique côté carrosserie de véhicule. Un moyeu (17) a une section d'évidement interne (29) sur un côté de diamètre interne d'une section interne dans la direction axiale, la section d'évidement interne (29) ayant, sur sa surface périphérique interne, une section de surface de montage cylindrique (30) qui est coaxiale à l'axe central du moyeu (17), et un élément de support cylindrique creux (67) est monté et fixé à l'intérieur de la section d'évidement interne (29) dans un état dans lequel une section de surface de guidage cylindrique (70) disposée sur la surface périphérique externe de l'élément de support est insérée dans la section de surface de montage (30). Un rotor (61) servant d'armature est fixé à une section interne axiale de l'élément de support (67) pour être coaxial à l'élément de support (67), et un appareil de communication sans fil (12) est disposé sur l'intérieur de l'élément de support (67) dans la direction radiale. Un trou traversant (34), dans lequel est disposé un câblage (57), est formé dans la surface inférieure (31) de la section d'évidement interne (29).
(JA) 発電機および無線通信器の設置に伴う軸方向寸法の増大を最小限に抑え、車輪に取り付けられたセンサに十分な電力を供給でき、かつ、センサの出力信号を車体側の電子機器に無線送信できる、車輪支持用転がり軸受ユニットを提供する。ハブ17は、軸方向内側部の内径側に、ハブ17の中心軸と同軸の円筒面状の嵌合面部30を内周面に有するインナ凹部29を備え、インナ凹部29の内側に、中空円筒状の支持部材67が、外周面に設けた円筒面状の案内面部70を嵌合面部30に嵌合させた状態で支持固定される。支持部材67の軸方向内側部に、電機子である回転子61が支持部材67と同軸に固定され、支持部材67の径方向内側に、無線通信器12が配置される。インナ凹部29の底面31に、配線57が配置される貫通孔34が開口する。
