Definitions
- the invention relates to a hydraulic control system for Hochflußanwen ⁇ applications in motor vehicles.
- the invention provides a way of making hydraulic control systems for Hoch ⁇ flow applications in motor vehicles cheaper.
- a hydraulic control system for Hochfluß ⁇ applications in motor vehicles in particular for active suspension and active steering, at least one passive high-flow valve, which is hydraulically controlled by at least one Niedrigflußventil.
- the invention makes use of the fact that low-flow valves are offered cost-effectively as a "package" with an integrated control unit (eg for brake control applications) .
- the low-flow valves are magnetically and / or electrically coupled to the control unit
- Such a package can according to the invention easily to extend the passive high flow valves by hydraulically coupling them to the low flow valves Based on such a structure according to the invention, various tasks of hydraulic control can be realized.
- FIG. 1 shows the logical structure of a hydraulic control system according to the invention for Hochflußanassembleen
- FIG. 2 shows an application example for the control system according to the invention.
- FIG. 3 is a hydraulic pressure control device for an active Fahrtechnik ⁇ control system with a hydraulic control system according to the invention.
- FIG. 1 shows the structure of a hydraulic control system 10 according to the invention.
- a controller 12 and low flow valves 14 coupled thereto constitute a package 16 for brake control applications.
- This two-level package 16 is extended by a third level, namely the high flow passive valves 18 .
- the passive high-flow valves 18 are hydraulically coupled to the Niedrigflußventile 14, so that the passive high-flow valves 18 through the Niedrigfluß valves 14 can be hydraulically controlled.
- the Niedrigflußventile 14 thus serve as pilot valves for the passive high-flow valves 18.
- the inventively extended package 16 is thus basically used for high-flow active applications.
- FIG. 2 shows how, for example, an oil flow can be controlled with the control system 10 according to the invention.
- the oil flow is adjusted via a passive high-flow valve in the form of a slide valve 20.
- the passive slide valve 20 is controlled by two Niedrigflußventile.
- the low flow valves are two 2/2-way valves 22, 24, which are otherwise used as ABS valves.
- the first valve is a "Normally Closed” valve, which is arranged in a pressure line, in which a system pressure pp prevails.
- the second valve 24 is a "normally open” valve, which is arranged in a return line to a tank in which there is a tank pressure pr.
- the two 2/2-way valves 22, 24 By means of a control device (not shown here), the two 2/2-way valves 22, 24 As a result of this precontrol, the control surface of the passive slide valve 20 can be acted upon by the two 2/2-way valves 22, 24 either with the system pressure pp or with the tank pressure pj With the addition of four 2/2-way valves, n / 3-way spool valve functions can also be implemented.
- An inventive control system 10 can also be used to control a pressure.
- a proportional brake control valve Proportional Brake Control Valve
- a passive proportional pressure relief valve or a proportional pressure relief valve The pressure limiting valve or the pressure reducing valve is in equilibrium with the brake control valve.
- an active proportional brake control valve with a passive proportional pressure relief valve is required.
- an active proportional brake control valve with a passive proportional pressure relief valve and n active proportional brake control valves with n-passive proportional pressure reducing valves are required.
- FIG. 3 shows, as a further application example, a hydraulic pressure control device 26 with which a front and a rear actuator 28 or 30 of a vehicle chassis can be actuated.
- the pressure control device 26 includes a motor-driven pump 32, which promotes hydraulic oil from a tank 34, and a hydraulic according to the invention Steuery system 10 with two connections Al, A2 and Bl, B2 for each actuator 28, 30 and a return line to the tank 34.
- a control unit 36 of the control system 10 controls a proportional pressure relief valve 38 and a proportional pressure reducing valve 40 and two 2/2
- the two 2/2-way valves 42, 44 serve as pilot valves for a directional control valve means 46 for determining the direction of actuator movement and for a blocking valve means 48, with which the front actuator 28 can be blocked.
- Both the proportional valves 38, 40 and the 2/2-way valves 42, 44 are active low flow valves, while the directional control valve means 46 and the blocking valve means 48, which may also be replaced by a similar valve means, are formed of passive high flow valves.
