Abstract
A suspension assembly for an electrified vehicle includes a first linkage rod coupled to a first bracket and a second linkage rod coupled to a second bracket. The first linkage rod is arranged at an angle relative to a central longitudinal axis so that as the first linkage rod extends from the axle housing toward the first bracket, the first linkage rod angles laterally outwardly and away from the central longitudinal axis. The second linkage rod is arranged at an angle relative to the central longitudinal axis so that as the second linkage rod extends from the axle housing toward the second bracket, the second linkage rod angles laterally outwardly and away from the central longitudinal axis.
Claims11
A suspension assembly comprising:
- a first bracket coupled to a first frame rail;
- a second bracket coupled to a second frame rail;
- a first linkage rod coupled between the first bracket and an axle housing, wherein the first linkage rod is arranged at an angle relative to a central longitudinal axis so that as the first linkage rod extends from the axle housing toward the first bracket, the first linkage rod angles laterally outwardly and away from the central longitudinal axis, wherein the first linkage rod is coupled to the axle housing at a location that is arranged laterally outwardly from the central longitudinal axis and closer to the first frame rail than the central longitudinal axis;
- and
- a second linkage rod coupled between the second bracket and the axle housing, wherein the second linkage rod is arranged at an angle relative to the central longitudinal axis so that as the second linkage rod extends from the axle housing toward the second bracket, the second linkage rod angles laterally outwardly and away from the central longitudinal axis, wherein the second linkage rod is coupled to the axle housing at a location that is arranged laterally outwardly from the central longitudinal axis and closer to the second frame rail than the central longitudinal axis, wherein the first linkage rod and the second linkage rod form a first pair of linkage rods, and a second pair of linkage rods are arranged symmetric to the first pair of linkage rods about a central lateral axis.
An electrified vehicle comprising;
- a chassis including a first frame rail and a second frame rail laterally separated from the first frame rail;
- a first bracket fixedly coupled to the first frame rail;
- a second bracket fixedly coupled to the second frame rail;
- a first axle assembly including a first axle housing arranged laterally between the first frame rail and the second frame rail;
- a second axle assembly including a second axle housing arranged on an opposing side of a central lateral axis from the first axle housing;
- an energy storage system supported on the chassis between the first frame rail and the second frame rail;
- and
- a suspension assembly including:
- a first linkage rod coupled between the first axle housing and the first bracket, wherein the first linkage rod is arranged at an angle relative to a central longitudinal axis so that as the first linkage rod extends from the first axle housing toward the first frame rail, the first linkage rod angles laterally outwardly and away from the central longitudinal axis, wherein the first linkage rod is coupled to the first axle housing at a location that is arranged laterally outward from the central longitudinal axis and closer to the first frame rail than the central longitudinal axis;
- and
- a second linkage rod coupled between the second bracket and the second axle housing, wherein the second linkage rod is arranged at an angle relative to the central longitudinal axis so that as the second linkage rod extends from the second axle housing toward the second bracket, the second linkage rod angles laterally outwardly and away from the central longitudinal axis, wherein the second linkage rod is coupled to the second axle housing at a location that is arranged laterally outwardly from the central longitudinal axis and closer to the second frame rail than the central longitudinal axis.
