Abstract:
1. A stabilizer system for a vehicle, comprising: a pendulum proportional flow valve; a first hydraulic cylinder and piston assembly mounted to a first vehicle support; a second hydraulic cylinder and piston assembly mounted to a second vehicle support, wherein one of the first vehicle support or the second vehicle support is positioned forward of the other; wherein the flow valve controls fluid flow to the first and second hydraulic cylinders, and wherein the proportional flow valve is actuated upon tilting from an untilted position, and wherein flow is increased to a piston of the first and second hydraulic cylinder assemblies in proportion to a tilt angle when the vehicle is tilted to a first side, and wherein flow is increased to a cylinder of the first and second hydraulic cylinder assemblies in proportion to a tilt angle when the vehicle is tilted to a second side; and a counterbalance control valve in fluid communication with the first and second hydraulic cylinders and the proportional flow valve.
