Abstract
A sensor bearing unit includes a bearing having a first ring and a second ring, and an impulse ring provided with a target holder, with a target mounted on the target holder, and with a sleeve secured to the first ring. The target holder having a mounting portion secured to the first ring of the bearing. The target holder has at least anti-rotation feature axially spaced apart from a free end of the mounting portion and cooperating with a complementary anti-rotation feature of the first ring so as to prevent angular movement of the impulse ring relative to the first ring. The anti-rotation feature of the target holder extends into the complementary anti-rotation feature of the first ring.
Claims10
A sensor bearing unit comprising:
- a bearing comprising a first ring and a second ring centered on an axis, and
- an impulse ring provided with a target holder and with a target mounted on the target holder, the target holder comprising a mounting portion secured to the first ring of the bearing, wherein:
- the target is radially spaced and radially outward from the inner ring and a radially outermost surface of the outer ring;
- the target holder comprises anti-rotation means axially spaced apart from a free end of the mounting portion and cooperating with complementary anti-rotation means of the first ring so as to prevent angular movement of the impulse ring relative to the first ring, the anti-rotation means of the target holder extending into the complementary anti-rotation means of the first ring or vice versa;
- and
- the anti-rotation means are radially inward from the inner ring and the outer ring.
A sensor bearing unit comprising:
- a bearing comprising a first ring and a second ring centered on an axis, and
- an impulse ring provided with a target holder and with a target mounted on the target holder, the target holder comprising a mounting portion secured to the first ring of the bearing, wherein
- the target holder comprises anti-rotation means axially spaced apart from a free end of the mounting portion and cooperating with complementary anti-rotation means of the first ring so as to prevent angular movement of the impulse ring relative to the first ring, the anti-rotation means of the target holder extending into the complementary anti-rotation means of the first ring or vice versa, wherein the complementary anti-rotation means of the first ring of the bearing comprise an anti-rotation recessed portion, wherein the anti-rotation recessed portion comprises at least one radial groove formed on the lateral face of the first ring of the bearing, the target holder comprising at least one boss extending into the radial groove and being of complementary shape, the boss forming at least partly the anti-rotation means of the target holder.
A sensor bearing unit comprising:
- a bearing comprising a first ring and a second ring centered on an axis, and
- an impulse ring provided with a target holder and with a target mounted on the target holder, the target holder comprising a mounting portion secured to the first ring of the bearing, wherein
- the target holder comprises anti-rotation means axially spaced apart from a free end of the mounting portion and cooperating with complementary anti-rotation means of the first ring so as to prevent angular movement of the impulse ring relative to the first ring, the anti-rotation means of the target holder extending into the complementary anti-rotation means of the first ring or vice versa, wherein the complementary anti-rotation means of the first ring of the bearing comprise an anti-rotation recessed portion, wherein the anti-rotation recessed portion comprises an eccentric groove formed on the lateral face of the first ring of the bearing, the target holder comprising an eccentric rib extending into the eccentric groove and being of complementary shape, the eccentric rib forming at least partly the anti-rotation means of the target holder.
