Bearing device and manufacturing method thereof

摘要

A bearing device includes a first bearing element and at least one second bearing element that is movably supported relative to the first bearing element and at least one seal unit that includes at least one attachment element that plays a role in attaching at least one seal element of the seal unit to the first bearing element. The attachment element includes at least a part of an antilock braking system (ABS) ring. The ABS ring may include through openings and be usable with a sensor that senses a magnetic field generated by the ABS ring.

1. A bearing device comprising:
a first bearing element; at least one second bearing element, wherein the first bearing element is movably supported relative to the at least one second bearing element, the first bearing element and the at least one second bearing element radially and axially defining a space therebetween; at least one seal unit including at least one attachment element coupled with the first bearing element, and at least one seal element coupled with the at least one attachment element; and a ring component coupled with the at least one second bearing element and extending radially therefrom, wherein the ring component moves with the at least one second bearing element, and the at least one seal element seals with the ring component, wherein the attachment element defines a plurality of through-holes that are detectable to determine a speed of the first bearing element, the plurality of through-holes being movable with the first bearing element and providing at least a part of an antilock braking system (ABS) ring, and wherein at least a majority of the ring component is disposed in the space, and the plurality of through-holes are disposed radially outside of the space.
