Control apparatus for hydrostatic motor vehicle steering apparatus |
摘要 |
The invention relates to hydrostatic steering control apparatus of the type having a hydrostatic steering motor which is connected to wheels to be steered and a steering wheel controlled metering or quantity setting device for controlling the hydraulic fluid supplied to the steering motor. A hydraulic amplifier connected to the steering motor has the characteristics of generating and transmitting undesired pressure pulses to the steering motor during steering switching operations. One way pre-stressed check valves are disposed respectively between the quantity setting apparatus motor ports and the steering motor ports. The check valves open in the direction of the steering motor ports and operate to allow bypassing the amplifier during the steering switching operations.
