ROLLING ELEMENT BEARING UNIT WITH SENSOR AND HUB UNIT WITH SENSOR |
摘要 |
A sensor-equipped hub unit comprises a hub unit 1 having a wheel-side raceway member 4, a body-side raceway member 5, and two rows of rolling bodies 6, and a sensor device 2 provided on the hub unit 1. The sensor device 2 has a magnetostrictive sensor 31 for detecting a reverse magnetostrictive effect of the raceway member 4 produced by a force exerted thereon by the rolling bodies 6. The sensor device 2 detects rotation from the number of repetitions of a variation in strain and also detects the force acting on the wheel-side raceway member 4 from the amplitude of strain. <IMAGE> |
