Abstract:
A steering system for a vehicle includes a fluid pump, an actuator in selective fluid communication with the fluid pump, a hydrostatic steering system and an electro-hydraulic steering system. The hydrostatic steering system includes a fluid controller having a first proportional valve in fluid communication with the fluid pump and a fluid meter in fluid communication with the first proportional valve and the actuator. The electro-hydraulic steering system includes a second proportional valve in selective fluid communication with the fluid pump and the actuator. The second proportional valve is disposed in parallel to the first proportional valve. The electro-hydraulic steering circuit further includes a load-reaction switching valve assembly disposed in series with the first proportional valve of the hydrostatic steering system. The load-reaction switching valve allows fluid communication between the actuator and the fluid controller when the first proportional valve is in a neutral position.
