Wheel operating force sensor |
摘要 |
A wheel operating force sensor includes: an attachment fixed to a vehicle body member supported by a suspension device; a hub to which a wheel is fixed and which is rotatably supported about a wheel axis with respect to the attachment; a sensing body having a tube formed substantially concentrically with the wheel axis, one end of the tube being fixed to the attachment, and the other end being connected to the hub, with a hub bearing being interposed between the other end and the hub; and a component force sensing unit having a bridge circuit including per component force at least four strain gauges that are provided on a circumferential surface of the tube of the sensing body. The hub bearing has: a radial bearing provided between the sensing body and the hub and receiving a load in a radial direction; and a thrust bearing provided between the sensing body and the hub and receiving a load in a thrust direction, and moreover provided separately from the radial bearing. |

1. A wheel operating force sensor comprising:
an attachment fixed to a vehicle body member supported by a suspension device; a hub to which a wheel is fixed and which is rotatably supported about a wheel axis with respect to the attachment; a sensing body having a tube formed substantially concentrically with the wheel axis, one end of the tube being fixed to the attachment, and the other end being connected to the hub, with a hub bearing being interposed between the other end and the hub; and a component force sensing unit having a bridge circuit including per component force at least four strain gauges that are provided on a circumferential surface of the tube of the sensing body, wherein the hub bearing has: a radial bearing provided between the sensing body and the hub and receiving a load in a radial direction; and a thrust bearing provided between the sensing body and the hub and receiving a load in a thrust direction, and moreover provided separately from the radial bearing. |
