Title:
SENSOR-EQUIPPED BEARING FOR WHEEL
Document Type and Number:
WIPO Patent Application WO/2007/066593
Kind Code:
A1
Abstract:
A sensor-equipped bearing for a wheel, with which a load detection sensor can
be compactly installed on a vehicle, that can detect a load on the wheel, and that
can be mass-produced at low costs. The bearing has an outer member having double-row
rolling surfaces on its inner surface, an inner member having formed on it rolling
surfaces opposite the rolling surfaces of the outer member, and double-row rolling
bodies interposed between the rolling surfaces of the inner and outer members.
The bearing rotatably supports the wheel relative to a vehicle body. In the bearing,
a sensor unit is attached to a stationary-side member out of the outer member and
the inner member. The sensor unit is composed of a sensor installation plate and
of a strain sensor or a displacement sensor that is attached to the sensor installation
member, or alternatively, the sensor unit is composed of an installation member
formed from a strain-inducing material and a detection coil that is attached
to the installation member. The sensor installation member or the installation
member formed from the strain-inducing material has at least two contact/fixation
sections engaged to the stationary-side member. The strain sensor or the displacement
sensor or the detection coil is placed at at least one portion between adjacent
contact/fixation sections.
