Abstract

A motor vehicle rear suspension includes left and right trailing links mounted, at respective forward ends thereof, to a vehicle body for pivoting movement about a transversely-extending axis. The trailing links extend rearward from the axis, and each has a wheel carrier attached thereto adjacent a rear end thereof. Left and right leaf springs are fixed, at respective forward ends thereof, to the vehicle body and extend rearward therefrom alongside and generally parallel with their respective trailing links. Rear ends of the leaf springs contact their respective trailing links and applying spring-force thereto.

First claim

What is claimed is:

1. A motor vehicle rear suspension, comprising:
left and right trailing links mounted, at respective forward ends thereof, to a vehicle body for pivoting movement about a transversely-extending axis and extending rearward from the axis, each of the trailing links comprising a wheel carrier attachment region adjacent a rear end thereof and a bearing element projecting outboard therefrom relative to a longitudinal centerline of the vehicle body; and
left and right leaf springs fixed, at respective forward ends thereof, to the body and extending rearward therefrom alongside and outboard of the respective trailing links, each of the leaf springs having a rear end contacting and applying spring-force to the respective bearing element.

2. The suspension of claim 1 , further comprising a transversely-extending axle bridge connecting the left and right trailing links.

3. The suspension of claim 1 , wherein the leaf springs extend generally parallel to a vehicle X-axis.

4. The suspension of claim 1 , wherein the leaf springs contacts upward-facing surfaces of the respective bearing elements.

5. A motor vehicle comprising:
a sprung body;
left and right trailing links mounted, at respective forward ends thereof, to the body for pivoting movement about a transversely-extending axis and extending rearward from the axis, each of the trailing links comprising a wheel carrier attachment region adjacent a rear end thereof;
a left and a right bearing element extending outboard from the respective trailing link: and
left and right leaf springs fixed, at respective forward ends thereof, to the body and extending rearward therefrom alongside and outboard of the respective trailing link, each of the leaf springs having a rear end contacting and applying spring-force to the respective bearing element.

6. The motor vehicle of claim 5 , further comprising a transversely-extending axle bridge connecting the left and right trailing links.

7. The motor vehicle of claim 5 , wherein the leaf springs extend generally parallel to a vehicle X-axis.

8. The motor vehicle of claim 5 , wherein the leaf springs contact an upward-facing surface of the respective bearing element.

9. A motor vehicle rear suspension, comprising:
left and right trailing links mounted to a vehicle body for pivoting movement about a transversely-extending axis and extending rearward from the axis, each having a wheel carrier attached thereto adjacent a rear end thereof, each trailing link comprising a bearing element extending transversely outboard therefrom relative to a longitudinal center-line of the vehicle body; and
left and right cantilever springs fixed against rotation about a second transversely-extending axis at their respective forward ends to the body and extending rearward therefrom alongside and outboard from the respective trailing link, rear ends thereof contacting and applying spring-force to the respective bearing element.

10. The suspension of claim 9 , further comprising a transversely-extending axle bridge connecting the left and right trailing links.

11. The suspension of claim 9 , wherein the cantilever springs extend generally parallel to a vehicle X-axis.

12. The suspension of claim 9 , wherein each of the cantilever springs contacts an upward-facing surface of the respective bearing element.
