Modular independent suspension and method of producing the same
View Patent ↗A method of producing a modular independent suspension having portal wheel ends is disclosed herein. The method includes, but is not limited to, assembling a first flank component and a second flank component to opposite sides of a sub-frame configured to receive a carrier. The method further includes assembling a first upper control arm and a first lower control arm to the first flank component. The method further includes assembling a second upper control arm and a second lower control arm to the second flank component. The method further includes assembling a first portal wheel end to the first upper control arm and the first lower control arm. The method still further includes assembling a second portal wheel end to the second upper control arm and the second lower control arm.
1. A modular independent suspension having portal wheel ends, the modular independent suspension comprising:
a sub-frame configured to receive a carrier, the sub-frame having a first side and a second side, the first side defining a first plurality of sub-frame bolt holes arranged vertically, and the second side defining a second plurality of sub-frame bolt holes arranged vertically;
a first flank component having a first plurality of first flank bolt holes arranged vertically and configured to align with less than all of the first plurality of sub-frame bolt holes, the first plurality of first flank bolt holes being aligned with a first subset of the first plurality of sub-frame bolt holes and the first flank component being coupled to the first side of the sub-frame via a first plurality of fasteners extending through the first plurality of first flank bolt holes and the first subset of the first plurality of sub-frame bolt holes;
a second flank component having a second plurality of second flank bolt holes arranged vertically and configured to align with less than all of the second plurality of sub-frame bolt holes, the second plurality of second flank bolt holes being aligned with a second subset of the second plurality of sub-frame bolt holes and the second flank component being coupled to the second side of the sub-frame via a second plurality of fasteners extending through the second plurality of second flank bolt holes and the second subset of the second plurality of sub-frame bolt holes;
a first control arm assembly coupled to the first flank component;
a second control arm assembly coupled to the second flank component;
a first portal wheel end coupled to the first control arm assembly; and
a second portal wheel end coupled to the second control arm assembly,
wherein the first plurality of first flank bolt holes comprises fewer bolt holes than the first plurality of sub-frame bolt holes and wherein the second plurality of second flank bolt holes comprises fewer bolt holes than the second plurality of sub-frame bolt holes, wherein the first flank and the second flank may be selectively mounted to the sub-frame at a plurality of different heights.
2. The modular independent suspension of claim 1 , wherein the first control arm assembly comprises a first upper control arm and a first lower control arm and wherein the second control arm assembly comprises a second upper control arm and a second lower control arm.
3. The modular independent suspension of claim 1 , wherein a first sub-frame bore is defined in the first side of the sub-frame, wherein a second sub-frame bore is defined in the second side of the sub-frame, wherein a first flank bore is defined in the first flank component, wherein a second flank bore is defined in the second flank component, wherein the first flank bore is substantially aligned with the first sub-frame bore, and wherein the second flank bore is substantially aligned with the second sub-frame bore.
4. The modular independent suspension of claim 3 , wherein a first half shaft is coupled to the first portal wheel end such that the first half shaft extends through the first flank bore and the first sub-frame bore, and wherein a second half shaft is coupled to the second portal wheel end such that the second half shaft extends through the second flank bore and the second sub-frame bore.
5. The modular independent suspension of claim 1 , further comprising:
a first spacer component disposed between the first flank component and the first side of the sub-frame; and
a second spacer component disposed between the second flank component and the second side of the sub-frame.
