摘要： A wheel bearing includes a rotary element mounted on the wheel and configured to rotate together with the wheel; a non-rotary element fixedly mounted on the vehicle body; one or more rolling bodies provided between the rotary element and the non-rotary element; a sensor target mounted on the rotary element and configured to rotate together with the rotary element; and a wheel speed sensor disposed adjacent to the sensor target to sense a rotational speed of the rotary element. The wheel speed sensor may include a first sensing part and a second sensing part configured to sense a change in magnetic field caused by the rotation of the sensor target, and the second sensing part may be disposed to be spaced apart from the first sensing part in longitudinal and widthwise directions of the wheel speed sensor.

摘要： A sensor for measuring a rotation speed of a magnetic encoder includes a first magnetic detector detecting a magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a first electrical signal, a second magnetic detector detecting the magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a second electrical signal, a first output signal generator for generating and outputting first rotation data including information indicating a rotation speed of a wheel based on the first electrical signal, and a second output signal generator configured to generate second rotation data including information indicating a rotation speed of the wheel based on the second electrical signal. The information indicating the rotation speed in the second rotation data may have a higher resolution than the information indicating the rotation speed in the first rotation data.

摘要： A wheel bearing assembly according to one embodiment of the present disclosure may comprise a wheel hub, at least one inner ring, an outer ring, and one or more rolling elements. According to one embodiment of the present disclosure, an accommodation space may be formed inward of a vehicle-body-side end portion of the wheel hub to accommodate a constant velocity joint, and a plurality of recesses for accommodating rotating elements of the constant velocity joint are formed on an inner peripheral surface of the accommodation space to be spaced apart from each other along a circumferential direction. According to one embodiment of the present disclosure, a first heat-treated hardened portion may be formed on the inner peripheral surface of the accommodation space, wherein the first heat-treated hardened portion may be formed to have portions with which the rotating elements of the constant velocity joint is brought into contact. According to one embodiment of the present disclosure, a second heat-treated hardened portion may formed on an outer peripheral surface of the wheel hub, wherein the first heat-treated hardened portion and the second heat-treated hardened portion may be formed so as not to overlap each other.

摘要： There is provided a bearing device in which an inner member and an outer member are connected to each other in a relative rotation relationship through rolling elements. A sealing member may be provided in an end portion of the bearing device so as to prevent an external foreign substance from flowing into the bearing device or prevent lubricant filled in the bearing device from leaking out of the bearing device. The sealing member may comprise a frame constituting a basic body and an elastic sealing portion attached to the frame, and the elastic sealing portion may comprise one or more sealing lips. The one or more sealing lips may comprise a main sealing lip configured to perform a main sealing function and an auxiliary sealing lip located inward of the main sealing lip.

摘要： A wheel bearing assembly may include a wheel hub having a hub flange; one or more inner rings configured to be mounted to one side of the wheel hub; an outer ring provided radially outward of the one or more inner rings; a spacer coupled to a vehicle-body-side end portion of an inner ring disposed on a vehicle-body-side; and one or more rolling elements provided between the one or more inner rings and the outer ring. The one or more inner rings may be configured to be held on the wheel hub by plastically deforming a vehicle-body-side end portion of the wheel hub in a radially outward direction. A plurality of recesses for accommodating rotating elements of a constant velocity joint may be formed on an inner peripheral surface of the vehicle-body-side end portion of the wheel hub in a spaced-apart relationship with each other along a circumferential direction.
