  • Steering system for articulated vehicles
    Patent number: 7412315
    Abstract: A steering system for an articulated vehicle has a microprocessor connected to a proportional solenoid valve which controls the direction, amount and rate of flow of hydraulic fluid to and from hydraulic articulation cylinders, which provide articulation between the frames of the articulated vehicle. A positional feedback sensor measures the angle of articulation between the frames and communicates the angle of articulation to the processor. A gear sensor monitors the gear that the vehicle is in and communicates it to the processor. A user input device allows a user to select the desired level of steering sensitivity and also allows the user to input the size of the tires installed on the vehicle. A steering device allows the operator to provide steering input and communicates electrical steering signals to the processor based on the steering input from the operator.
