In addition to attaching the magnetic material, attach it to the fixed member on the vehicle body side that does not rotate.
There is a proximity switch in which a coil is wound around a magnetized iron core so as to face the outside of the magnetic material. As the wheel rotates, the uneven part of the magnetic material rotates on the front surface of the proximity switch, which generates a voltage due to electromagnetic induction in the coil each time a protrusion passes, and the rotational speed of the wheel is detected based on the cycle of this induced voltage. ing.

However, since brake pads are air-cooled, they cannot be sealed, so there is a risk that dirt or the like can get stuck between the protrusions of the magnetic material, or that the protrusions can be damaged by pebbles, causing the pulse detector to malfunction. There is.

In the sealed space, a pulse generator is provided on the rotating side of the inner periphery of the outer member and the outer periphery of the inner member, and a pulse detector is provided on the non-rotating side. The pulse generator has protrusions arranged in the circumferential direction, and causes the pulse detector to generate a pulse each time the pulse generator passes the protrusions. A sealing member is preferably used as the sealing means, and a pulse generator having a plurality of protrusions arranged in the circumferential direction is preferably used as the pulse generator. In addition, as a pulse detector, one in which a coil is wound around a magnetized iron core is suitably used.

It is commonly used as a bearing seal because it includes a rolling element inside and is sealed by a sealing means. The rotation of a pulse generator equipped with a protrusion made of magnetic material generates pulses in the pulse detector, and the period of the generated pulses is determined by the rotational speed of the magnetic material, allowing the rotational speed of the axle to be determined. .
