Wheel Having a Stiffening Rib
A wheel is provided including a disc face, an open end opposing the disc face, and a wheel rim extending between the disc face and the open end, the wheel rim including a rib extending radially inward from the rim and a rim section including the rib.
1 . A wheel comprising:
a disc face; and
a rim circumscribing the disc face and extending between the disc face and an open end thereof, the rim including:
a rib extending radially inward from the rim, and
a rim section including the rib having a second moment of area configured to enable the wheel to have:
a) a substantially similar load rating and/or tire pressure rating as a wheel of similar size without the rib; and
b) a lower weight than the wheel of similar size.
2 . The wheel of claim 1 , further comprising a second rib extending radially inward from the rim proximate the disc face.
3 . The wheel of claim 1 , wherein the wheel complies with SAE J1865 brake clearance standards.
4 . The wheel of claim 1 , wherein a weight of the wheel is between 34 pounds to 39 pounds.
5 . The wheel of claim 4 , wherein the rib extends between 0.276 in to 0.591 in radially inward.
6 . The wheel of claim 5 , wherein the rib extends between 0.276 in to 0.394 in radially inward.
7 . The wheel of claim 4 , wherein the rim section has a second moment of area between 0.0150 in 4 to 0.0600 in 4 .
8 . The wheel of claim 7 , wherein the rim section has a second moment of area between 0.0170 in 4 to 0.0400 in 4 .
9 . The wheel of claim 1 , wherein the rim section extends:
a first distance from a centroid of the rib to the open end, and
a second distance substantially equal to the first distance from the centroid of the rib toward the disc face.
10 . The wheel of claim 1 , wherein the rim further comprises a tire side profile including:
an open end flange,
a disc face flange,
a first angle wall extending from the disc face flange toward the open end flange;
a second angle wall extending from the open end flange toward the disc face flange; and
a drop well connecting the first angle wall and the second angle wall.
11 . The wheel of claim 4 , wherein the wheel is formed from a 6xxx aluminum alloy.
12 . The wheel of claim 1 , wherein the weight of the wheel is between 50 pounds to 52 pounds.
13 . The wheel of claim 12 , wherein the rib extends between 0.0394 in to 0.591 in radially inward.
14 . The wheel of claim 12 , wherein the rib extends between 0.0787 in to 0.157 in radially inward.
15 . The wheel of claim 12 , wherein the rim section has a second moment of area between 0.0120 in 4 to 0.04 in 4 .
16 . The wheel of claim 15 , wherein the rim section has a second moment of area between 0.0120 in 4 to 0.0140 in 4 .
17 . The wheel of claim 12 , wherein the rim section extends:
a first distance from a centroid of the rib to the open end, and
a second distance substantially equal to the first distance from the centroid of the rib toward the disc face.
18 . The wheel of claim 12 , wherein the wheel is formed from a 6xxx aluminum alloy.
19 . A method for making a wheel comprising:
at least one of forging, casting, or machining a wheel, the wheel having a disc face, a rim circumscribing the disc face, the rim having an open end distal to the disc face and extending between the disc face and the open end, the rim including:
a rib extending radially inward therefrom, and
a rim section including the rib having a second moment of area configured to enable the wheel to have:
a) a substantially similar load rating and/or tire pressure rating as a wheel of similar size without the rib; and
b) a lower weight than the wheel of similar size.
20 . The method of claim 19 , wherein the rim further comprises a tire side profile including:
an open end flange,
a disc face flange,
a first angle wall extending from the disc face flange toward the open end flange;
a second angle wall extending from the open end flange toward the disc face flange; and
a drop well connecting the first angle wall and the second angle wall and wherein the wheel is forged or cast from a 6xxx aluminum alloy.
