Sensor-equipped hub units 34a attached to respective drive wheels 34 each have a sensor device comprising a sensor 36 for detecting the ground contact load on the wheel 34. A control unit 31 has a traction controller 32, whereby when the ground contact load value output from one of the ground contact load sensors 36 while the vehicle is traveling straight is outside a predetermined range, the drive wheel 34 is controlled so as to return the ground contact load value to the original value.

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.

A hub unit with a sensor comprises a hub unit 1 including a body-side raceway member 3, a wheel-side raceway member 4 and two rows of rolling elements 5, and a sensor device 2. The sensor device 2 includes a magnetostrictive sensor 8 for detecting the inverse magnetostrictive effect, and the magnetostrictive sensor 8 is mounted to the body-side raceway member 3 so as to be capable of measuring the tensile strain in the uppermost part of an inner wheel 17 of the wheel-side raceway member 4. From the output of the magnetostrictive sensor 8, the tire grounding load and the rotational velocity are detected.

Balls are interposed between respective raceway surfaces of inner and outer ring members, and a seal apparatus is provided between shoulder portions of the inner and outer ring members. The seal apparatus comprises an outer ring-side seal ring fixed to the outer ring member, and an inner ring-side seal ring fixed to the inner ring member. A pulser ring is fixed to a ring-shaped core metal of the inner ring-side seal ring. In an outer diameter side of the ring-shaped core metal of the outer ring-side seal ring, a magnetic sensor is molded with resin by an external member to be integrated therein. A connector connected to the magnetic sensor is formed consecutive with the external member.
