- An object of the present invention is to provide a hub unit with a sensor capable of accurately determining a brake torque.
- the hub unit with a sensor includes a rotating track member to which wheels are mounted, a fixed track member fixed to a vehicle body, and a rolling element disposed between the two track members.
- the brake carrier is integrally formed with the fixed-side raceway member of the hub unit.
- the sensor device has a brake torque detecting device provided on the fixed-side track member.
- the brake carrier is physically attached to the fixed-side raceway member of the hubette," says the brake carrier. Instead of being attached to the vehicle body via the knuckle, the brake The lipper does not depend on the vehicle body side, and the fixed side track member of the hub unit
- the brake caliper is integrally attached to the fixed-side track member of the hub cut, and the sensor device is provided on the fixed-side track member. Since the brake torque detecting device is provided, it is possible to detect a brake torque corresponding value at a position close to the wheel side, and to obtain accurate brake torque information.
- the brake torque obtained in this way is compared with, for example, a predetermined torque value set in advance, and when the torque falls below the predetermined torque value while driving, it is determined that the brake has been released and the brake is released. It can be used for such control.
- the fixed-side raceway member extends radially outward and has a brake carrier and a carrier to which the ° can be attached. It is preferable that a mounting portion be provided, and the brake torque detecting device be provided at a base end portion of the caliper mounting portion.
- the carrier mounting part may be a carriage mounting arm integrally formed on the fixed-side track member, and the carrier mounted on the fixed-side track member by a bolt or the like. Mounting may be performed. Also, when mounting the brake calipers to the calipers mounting part, the calipers may be directly supported by the calipers mounting part, or the calipers may be mounted.
- the supporting member may be screwed to the mounting portion of the carrier, and the brake mounting force may be applied to the mounting portion of the brake carrier. Deforms the cylindrical fixed-side raceway member. At the radially outer end (free end) of the mounting portion of the carrier, the amount of displacement becomes maximum, and at the base end, which is the fixed end, the internal distortion becomes maximum.
- the above-mentioned carrier mounting portion makes it easy to provide a brake caliper integrally with the fixed-side raceway member of the hub unit, thereby simplifying the configuration of the hub unit with the sensor. It can be said that.
- a strain sensor such as an electric resistance type strain gauge, a magnetostrictive sensor, a piezoelectric force sensor (torque sensor), a capacitance force sensor (torque sensor), and the like can be used.
- electric resistance type strain gauges are preferred. Since the brake carrier is integrally attached to the fixed-side track member of the hapunit, high accuracy can be achieved even when a simple strain gauge is used as the brake torque detector. Brake torque information can be obtained, thereby simplifying a sensor-equipped hapunit.
