Document Type and Number:
WIPO Patent Application WO/2024/085740
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, provided is a vehicle wheel bearing configured such that a vehicle wheel is rotatably mounted to and supported by a vehicle body. The vehicle wheel bearing according to an embodiment of the present invention may include: a wheel hub provided with a wheel-mounting flange; an inner ring mounted on the outer circumferential surface of the wheel hub; an outer ring provided with a vehicle body-side mounting flange; a plurality of rolling elements that support the wheel hub and the inner ring so that the wheel hub and the inner ring can rotate relative to the outer ring; an outboard-side sealing member that seals a space between the wheel hub and the outer ring; a target ring mounted on one side of the inner ring and rotating together with the inner ring; and a sensor assembly that detects information about an operating state of the vehicle. According to an embodiment of the present invention, the sensor assembly may include a wheel speed sensing unit that measures the rotation speed of the wheel by detecting changes in the magnetic field generated by a sensor target of the target ring that rotates together with the vehicle wheel. A sealing portion for preventing external foreign substances from entering inside is provided on one side of the sensor assembly.
