Abstract

The invention relates to a hydraulic steering facility for mobile systems, with a steering circuit for a steering facility and a working circuit for a working hydraulic system, whereby the steering circuit and the working hydraulic system are connected to a supply pump via a shared flow dividing valve and the flow dividing valve is connected to a load signal connection of the steering device. It is provided that the steering facility has an adjustable input choke that is connected via an inflow connection of the steering facility to the flow dividing valve, between the load signal connection and downstream of the input choke, a parallel circuit consisting of a choke and an adjustable second load signal choke is arranged, and the load signal connection is further connected via an adjustable first load signal choke to a return flow connection of the steering facility.

Claims (9)

1. A hydraulic steering facility for mobile systems, with a steering circuit for a steering facility and a working circuit for a working hydraulic system, whereby the steering circuit and the working hydraulic system are connected to a supply pump via a shared flow dividing valve and the flow dividing valve is connected to a load signal connection of the steering device,

characterized in that the steering facility has an adjustable input choke that is connected via an inflow connection of the steering facility to the flow dividing valve, a parallel circuit consisting of a choke and an adjustable second load signal choke is arranged between the load signal connection and downstream of the input choke, and the load signal connection is further connected via an adjustable first load signal choke to a return flow connection of the steering facility; and

wherein the second load signal choke only closes at higher steering speeds.

2. The hydraulic steering facility according to claim 1 ,

characterized in that

the input choke and the second load signal choke have opposite closure characteristics.

3. The hydraulic steering facility according to claim 1 ,

characterized in that

the input choke is closed in the neutral position of the steering facility and the second load signal choke is opened.
