Title (EN) BEARING DEVICE FOR VEHICLE WHEEL
(FR) DISPOSITIF PALIER DE ROUE DE VÉHICULE
(JA) 車輪用軸受装置
Abstract:
(EN) This bearing device 1 for a vehicle wheel is provided with: a magnetic encoder 7 provided to an inner-side end of an inner race 4, which is an inward member; a cover 11 for covering an inner-side opening 2B of an outer race 2, which is an outward member, the cover 11 having opened therein a sensor attachment hole 11H in which an opening 11A and a thin-walled bottom 11B are formed; and a magnetic sensor 9 disposed facing the magnetic encoder 7 across the bottom 11B, the magnetic sensor 9 being inserted into the sensor attachment hole 11H in the cover 11 through the opening 11A. The bottom 11B in the sensor attachment hole 11H is formed in such a shape as to bulge toward the inner side.
(FR) L'invention concerne un dispositif palier 1 de roue de véhicule pourvu : d'un codeur magnétique 7 disposé à une extrémité côté intérieur d'une bague intérieure 4, qui est un élément intérieur ; d'un couvercle 11 servant à recouvrir une ouverture côté intérieur 2B d'une bague extérieure 2, qui est un élément extérieur, le couvercle 11 comportant un trou de fixation 11H de capteur s'ouvrant en son sein, dans lequel sont formés une ouverture 11A et un fond à paroi mince 11B ; et d'un capteur magnétique 9 disposé en regard du codeur magnétique 7 sur le fond 11B, le capteur magnétique 9 étant inséré dans le trou de fixation 11H de capteur ménagé dans le couvercle 11 à travers l'ouverture 11A. Le fond 11B du trou de fixation 11H de capteur adopte une forme de sorte à se courber vers le côté interne.
(JA) 車輪用軸受装置1は、内方部材である内綸4のインナー側の端部に設けられる磁気エンコーダ7と、開口部11A及び薄肉の底部11Bが形成されたセンサ取付穴11Hが開口されて、外方部材である外輪2のインナー側の開口部2Bを塞ぐカバー11と、カバー11のセンサ取付穴11Hに開口部11Aから挿入され、底部11Bを挟んで磁気エンコーダ7と対向して配設される磁気センサ9と、備え、センサ取付穴11Hにおける底部11Bは、インナー側に膨らんだ形状に形成されている。
