Abstract

Various suspension systems for vehicles are described that preferably comprise a multi-link suspension where one or more of the links can move independently of the other links. The multiple independent links are connected to an upright, vertical load reaction that is decoupled from horizontal load reaction, thus delivering a more comfortable ride and reduced feedback to the driver or operator of the vehicle. By eliminating that external feedback using the inventive subject matter discussed herein, vehicles can be safer and easier to control in all circumstances.

Claims (16)

1 . A suspension system for a vehicle, comprising:

a plurality of links comprising at least a first link and a second link, wherein a first end of the first link is coupled to a chassis of the vehicle and a second end of the first link is coupled to a knuckle at a first point, and wherein a first end of the second link is coupled to the chassis and a second end of the second link is coupled to the knuckle at a second point, and wherein the first link and the second link are unequal in length;

wherein the knuckle comprises a tire having a spindle snout tip;

wherein a distance between the first point and the spindle snout tip is approximately equal to a distance between the second point and the spindle snout tip.

2 . The suspension system of claim 1 , wherein the first point, the second point and the spindle snout tip define an isosceles triangle.

3 . The suspension system of claim 1 , wherein a first plane intersects the first point, the second point, the spindle snout tip, a third point where the first link couples to the chassis and a fourth point where the second link couples to the chassis.

4 . The suspension system of claim 1 , further comprising:

a third link and a fourth link, wherein a first end of the third link is coupled to the chassis and a second end of the third link is coupled to the knuckle at a third point, and wherein a first end of the fourth link is coupled to the chassis and a second end of the fourth link is coupled to the knuckle at a fourth point;

wherein a distance between the third point and the wheel centerline point is approximately equal to a distance between the fourth point and the wheel centerline point.

5 . The suspension system of claim 4 , wherein the third point, the fourth point and the wheel centerline point define an isosceles triangle.

6 . The suspension system of claim 4 , wherein a second plane intersects the third point, the fourth point, the wheel centerline point, a fifth point where the third link couples to the chassis and a sixth point where the fourth link couples to the chassis.

7 . The suspension system of claim 4 , wherein the first and second links comprise upper links connected to the knuckle at or above a vertical center of the knuckle, and wherein the third and fourth links comprise lower links connected to the knuckle at or below the vertical center of the knuckle.

8 . The suspension system of claim 7 , wherein the third and fourth links collectively comprise an A-arm.

9 . The suspension system of claim 7 , wherein each of the links pivots or moves independently of the other links.

10 . The suspension system of claim 1 , wherein the first link pivots or moves independently of the second link.

11 . The suspension system of claim 1 , wherein the spindle snout tip travels back and forth along an initial spindle line and remains on or within 2.0 cm over a +/−30 degree steering range, of an initial spindle line as the knuckle is rotated.
