  • Suspension system with a floating axle lock
    Patent number: 9254728
    Abstract: A suspension system for a vehicle includes a right front wheel, a left front wheel, a right rear wheel and a left rear wheel. A suspension system for the vehicle includes a first cylinder supporting the vehicle at the right front wheel in fluid communication with a second cylinder supporting the vehicle at the left front wheel, wherein the first and second cylinders form a virtual articulated front axle. The suspension system also includes a third cylinder supporting the vehicle at the right rear wheel and a fourth cylinder supporting the vehicle at the left rear wheel. The suspension system includes two spool valves in fluid communication with the first and second cylinders and intermediate the first and second cylinders. When one of the rear wheels is unweighted, an associate one of the spool valves closes and fluid flow between the first and second cylinders is blocked to create a virtual locked axle.
