Vehicle suspension system

1. A suspension system, comprising:

a hub carrier designed to couple to a wheel hub; and

a hub carrier mounting structure including:

a mounting flange removably attached to the hub carrier; and

an upper case and a lower case coupled to a support beam;

wherein the upper and lower cases are coupled via a first set of attachment devices and a second set of attachment devices that are positioned on opposing sides of the upper and lower cases;

wherein the first and second set of attachment devices have varying vertical heights; and

wherein the first set of attachment devices is positioned laterally inboard from the second set of attachment devices.

2. The suspension system of claim 1 , wherein the second set of attachment devices is positioned laterally between the first set of attachment devices.

3. The suspension system of claim 1 , wherein the mounting flange includes a forward end arranged longitudinally rearward from a lateral end of the support beam.

4. The suspension system of claim 1 , wherein the upper case includes a sidewall extending below an aperture designed to receive an axle shaft.

5. The suspension system of claim 1 , further comprising a leaf spring coupled to the hub carrier mounting structure.

6. The suspension system of claim 5 , wherein the leaf spring extends under the support beam.

7. The suspension system of claim 1 , wherein the support beam is a de Dion beam.

8. The suspension system of claim 1 , further comprising a differential rotationally coupled to an electric machine and an axle shaft rotatably coupled to a wheel assembly.

9. A de Dion suspension system, comprising:

a de Dion beam extending between a first hub carrier assembly and a second hub carrier assembly;

wherein the first hub carrier assembly comprises:

a hub carrier designed to couple to a wheel hub; and

a hub carrier mounting structure including:

a mounting flange removably attached to the hub carrier; and

an upper case and a lower case coupled to a support beam;

wherein the upper and lower cases are coupled via a first set of attachment devices and a second set of attachment devices positioned on opposing sides of the upper and lower cases;

wherein the upper case includes opposing sidewalls having varying vertical heights; and

wherein the first and second sets of attachment devices have varying vertical heights and wherein the first set of attachment devices is positioned laterally inboard from the second set of attachment devices.

10. The de Dion suspension system of claim 9 , further comprising a spring extending vertically under the de Dion beam.

11. The de Dion suspension system of claim 9 , further comprising a differential rotationally coupled to an electric machine and an axle shaft rotatably coupled to a wheel assembly.

12. The de Dion suspension system of claim 9 , further comprising a strut positioned laterally inboard from the upper case and the lower case.

13. The de Dion suspension system of claim 9 , further comprising a spring attachment component that is positioned below the lower case and is profiled to attach to a leaf spring.

14. A vehicle suspension system, comprising:

a hub carrier designed to couple to a wheel hub; and

a hub carrier mounting structure including:

a mounting flange removably attached to the hub carrier; and

an upper case and a lower case removably coupled one another and a de Dion beam, wherein the upper case and the lower case form an aperture that is designed to receive an axle shaft;

wherein the upper and lower cases are coupled via a first set of attachment devices and a second set of attachment devices that are positioned on opposing sides of the upper and lower cases;

wherein the first and second sets of attachment devices have varying vertical heights; and

wherein the upper case tapers in a rearward direction and the second set of attachment devices is positioned laterally between the first set of attachment devices.

15. The vehicle suspension system of claim 14 , wherein the first set of attachment devices is positioned vertically above the de Dion beam.

16. The vehicle suspension system of claim 14 , wherein the upper case includes a rib that extends longitudinally across at least a portion of its outer surface.

17. The vehicle suspension system of claim 14 , wherein the upper case tapers in a longitudinal direction towards the first set of attachment devices.

18. The vehicle suspension system of claim 14 , wherein the upper case is formed out of a continuous piece of material.
