  • Vehicle steering system of the by-wire design type
    Patent number: 8162095
    Abstract: A vehicle by-wire steering system includes a hydraulic default level. A hydraulic feed unit and a hydraulic actuating unit can be connected together by two hydraulic lines such that when an actuator is non-functional, a steering wheel rotational angle is transformed into a corresponding wheel steering angle by the hydraulic feed unit and the hydraulic actuating unit. The hydraulic lines can be connected together by a switchable steering valve, which is designed as a proportional servo valve, of which the flow cross section can be adjusted in essence continuously between the two extremes of completely closed and completely open.
    Type: Grant

  • Hydraulic steering system and method
    Patent number: 8006492
    Abstract: A hydraulic steering system has a steering linkage and an actuator actuating the steering linkage. Pressurized hydraulic fluid can be fed to the actuator and removed from the actuator through a return pipe. A device installed into the return pipe counteracts volume flow pulsations by damming up the hydraulic fluid return flow. The device dams up the hydraulic fluid only in the event of an occurrence of a volume flow pulsation.
