Abstract
A suspension assembly includes a first linkage rod coupled between an axle housing and a first frame rail, and a second linkage rod coupled between the axle housing and a second frame rail. 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 frame rail, 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 frame rail, the second linkage rod angles laterally outwardly and away from the central longitudinal axis.
Claims20
A suspension assembly for an electrified vehicle, the electrified vehicle including a chassis and an axle assembly, the chassis having a first frame rail and a second frame rail laterally separated from the first frame rail, the axle assembly including an axle housing arranged laterally between the first frame rail and the second frame rail, the suspension assembly comprising:
- a first linkage rod coupled between the axle housing and the first frame rail, 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 frame rail, the first linkage rod angles laterally outwardly and away from the central longitudinal axis;
- and
- a second linkage rod coupled between the axle housing and the second frame rail, 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 frame rail, the second linkage rod angles laterally outwardly and away from the central longitudinal axis.
An electrified vehicle comprising:
- a chassis including a first frame rail and a second frame rail laterally separated from the first frame rail;
- an axle assembly including an axle housing arranged laterally between the first frame rail and the second frame rail;
- an energy storage system supported on the chassis;
- a suspension assembly comprising:
- a first linkage rod coupled between the axle housing and the first frame rail, 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 frame rail, the first linkage rod angles laterally outwardly and away from the central longitudinal axis;
- and
- a second linkage rod coupled between the axle housing and the second frame rail, 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 frame rail, the second linkage rod angles laterally outwardly and away from the central longitudinal 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 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;
- a suspension assembly comprising:
- a first linkage rod coupled between the first axle housing and the first frame rail, 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;
- and
- a second linkage rod coupled between the second axle housing and the first frame rail, 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 frame rail, the second linkage rod angles laterally outwardly and away from the central longitudinal axis.
