| description | To provide a bearing device for wheel capable of improving muddy water resistant performance and detecting temperature rise of a bearing by a pulser ring mounted on the bearing.SOLUTION: A pulser ring 21 made of shape memory alloy is mounted on an end portion of a rotation-side member out of an outer member 4 and an inner member 3, the pulser ring 21 is composed of a cylindrical portion 21a fitted to the end portion of the rotation-side member, and a vertical plate portion 21b extending from the cylindrical portion 21a toward a stationary-side member and having a detected portion in a circumferential direction. A seal lip 23 having an interference to the stationary-side member is disposed on a tip of the vertical plate portion 21b, the vertical plate portion 21b is deformed in a direction to change a distance to a rotation sensor when the vertical plate portion 21b is over a shape recovery temperature, and abnormal temperature rise of the bearing is detected on the basis of output change of the rotation sensor 22 based on the deformation.SELECTED DRAWING: Figure 3
【課題】軸受に装着されるパルサーリングによって、シールの耐泥水性能を向上させ、かつ、軸受の温度上昇も検知することができる車輪用軸受装置を提供する。【解決手段】外方部材４と内方部材３のうちの回転側部材の端部に、形状記憶合金製のパルサーリング２１を装着し、このパルサーリング２１は、回転側部材の端部に嵌合される円筒部２１ａと、この円筒部２１ａから固定側部材に向かって延び、周方向に被検出部を有する立板部２１ｂとからなり、この立板部２１ｂの先端に固定側部材に対してシメシロを持ったシールリップ２３を設け、前記立板部２１ｂが形状回復温度を超えた時に、前記立板部２１ｂが前記回転センサとの距離が変化する方向に変形し、この変形に基づく回転センサ２２の出力変化に基づき軸受の異常昇温を検出することを特徴とする。【選択図】図３ |
