Abstract
A steering suspension of a vehicle includes a suspension upright and a mechanical component consisting of a radially outer ring of a wheel hub unit or of a rolling bearing forming part of a wheel hub unit. The outer ring is provided integral in one piece with a flange and a steering arm, extending radially cantilevered from the outer ring and the flange, with which it is also integral in one piece. On the side opposite to the steering arm the flange is integral in one piece with a pair of axially drilled radial lugs, configured to support, in use, a brake caliper.
Claims10
A mechanical component of a steering suspension of a vehicle, wherein the suspension comprises a suspension upright and a wheel hub unit, said mechanical component comprising a radially outer ring of the wheel hub unit or of a rolling bearing forming part of the wheel hub unit;
- said radially outer ring being bounded between a radially inner lateral surface and a corresponding radially outer lateral surface substantially coaxial with the radially inner lateral surface, the latter being provided with at least one annular raceway for respective rolling elements of the wheel hub unit;
- wherein, in combination:
- (i)—a steering arm provided with at least one respective attachment point for a steering tie rod extends radially from the radially outer lateral surface;
- (ii)—from a first axial end of the radially outer lateral surface extends radially cantilevered from the outer ring a flange configured to be in use attached integrally to the suspension upright;
- (iii)—the flange is provided radially cantilevered on a first side thereof with at least one pair of lugs obtained integrally in one piece with the flange and each provided with a first through-hole oriented parallel to an axis of symmetry of the outer ring and configured to support in use, integrally with the outer ring, a brake caliper;
- (iv)—the steering arm and the flange being integrally machined in one piece with the outer ring;
- and
- (v)—from the radially outer lateral surface of the outer ring extends radially cantilevered, a plate formed integrally in one piece with the flange and with the steering arm and which connects for a circumferential section of the flange, the flange itself to a portion of the steering arm which protrudes radially from the flange and which is immediately adjacent to the flange.
A steering suspension of a vehicle comprising a suspension upright and a wheel hub unit comprising, in turn, a mechanical component comprising a radially outer ring of the wheel hub unit or of a rolling bearing forming part of the wheel hub unit;
- wherein the outer ring is fixed integrally with the suspension upright by means of a flange formed integrally in one piece with the outer ring;
- wherein the outer ring is provided with a steering arm provided integrally in one piece with both a radially outer lateral surface thereof and with the flange, extending radially outward from the outer ring and the flange, and, on the side opposite to the steering arm, with a pair of axially drilled radial lugs, provided integrally in one piece with the flange and configured to support in use a brake caliper;
- and wherein, in combination, from said radially outer lateral surface extends, radially cantilevered, a plate formed integrally in one piece with the flange and with the steering arm and which connects for a circumferential section of the flange, the flange itself to a portion of the steering arm which protrudes radially from the flange and which is immediately adjacent to the flange.
A radially outer ring for a wheel hub unit or for a rolling bearing forming part of the wheel hub unit;
- said radially outer ring being bounded between a radially inner lateral surface and a corresponding radially outer lateral surface substantially coaxial with the radially inner lateral surface, the latter being provided with at least one annular raceway configured to receive in use respective rolling elements of the wheel hub unit;
- wherein, in combination:
- (i)—from the radially outer lateral surface extends radially cantilevered from the outer ring a steering arm provided with at least one respective engagement interface configured to receive in use a steering tie rod;
- (ii)—from a first axial end of the radially outer lateral surface extends radially cantilevered from the outer ring a flange configured to be in use connectable integrally to a suspension upright;
- (iii)—the flange is provided radially cantilevered on a first side thereof with at least one pair of lugs obtained integrally in one piece with the flange and each provided with a first through-hole oriented parallel to an axis of symmetry of the outer ring and configured to support in use, integrally with the outer ring, a brake caliper;
- (iv)—the steering arm and the flange being integrally machined in one piece with the outer ring;
- and
- (v)—from said radially outer lateral surface extends, radially cantilevered, a plate formed integrally in one piece with the flange and with the steering arm and which connects for a circumferential section of the flange, the flange itself to a portion of the steering arm which protrudes radially from the flange and which is immediately adjacent to the flange.
