Definitions
- sensors monitor the movement of the pivotable part, for example what via linear displacement sensors on the working cylinder, rotary sensors on the Axis of rotation or pressure sensors can be realized in the system of the working fluid can. Not only the reaching of the end position and the hydraulic unit can be signaled can be controlled accordingly, but there can also be a pinch protection or collision protection during the normally unobstructed swivel movement will be realized.
- the kinematics of the Articulation of the pivotable component are taken into account, which the on Component attacking forces to be overcome by the actuating arrangement affected.
- Bias valves have been proposed for this, for example the maximum system pressure during the automatic actuation of the moving Limit vehicle part and also a stop function in the event of failure or deliberate stopping of the hydraulic system. Finally, emergency operations were also possible so that in the event of a power supply failure, the pivotable Part can be moved manually.
- the object of the present invention is therefore an actuation arrangement of the type specified at the beginning, in which with a single, simply constructed and a safe one with a small number of complex and expensive components Stop and hold function guaranteed, regardless of the type of used Biasing valves.
- Any combination of automatic actuation, auxiliary power-assisted manual actuation, purely manual actuation - also in the event of a power failure of the automatic actuation arrangement - as well as protective functions such as pinch protection and holding function in every moment Location can be realized after a power failure.
- the present invention provided that in the at least one connecting line between the working spaces of the working cylinder arrangement at least a switching valve that completely releases or blocks this connecting line is used in series with a preload valve.
- a preload valve By hiring the Preload valve to a certain maximum pressure, that of the for the actuation necessary forces of the vehicle part can be determined by alternative supply the opposing working spaces of the working cylinder arrangement, whether this is due to opposing single-acting cylinders or a double-acting cylinder is realized, the automatic actuation of the pivotable part on the vehicle.
- the preload valve blocks the direct connection between the opposing work spaces the working cylinder arrangement in at least one direction.
- the invention provided that at least two parallel connecting lines between the working spaces of the working cylinder arrangement are available, in a connecting line two check valves open to each other are, two to be blocked in the parallel connecting line Check valves are used, and with another connecting line between the parallel connection lines that exist in each of the parallel connection lines branches between the two check valves and into which at least one that completely releases or blocks this connecting line Control valve is used in series with a preload valve.
- each one of the two workrooms can be supplied with the hydraulic medium while in the event of failure or deliberate shutdown of the hydraulic system, the connection between manufactured in opposite working spaces - and by the preload valve and the switching valve is controlled.
- the The switching valve is designed as a normally open valve. This is the effect of Preload valve not hindered during normal operation and also during emergency operation after appropriate activation for the safe stop function the switching valve can only be brought into the closed position for a short time at most.
- the switching valve can, but does not have to, be opened again, i.e. switched off, so that for example a manual operation the door, tailgate or the like. Or an emergency operation with overpressing the Preload valve is enabled.
- the or each lockable connecting line branches to the reservoir of the most distant connecting line of the working cylinder arrangement from their work rooms from.
- This can also be used on the cylinder arrangement Part of the system precisely to the prevailing and possible pressure conditions can be coordinated and all valves can be optimally tailored to the requirements be designed.
- the switching valve with a mechanically operated unlocking can be done directly or can be operated via a cable or the like, which is to be operated by the user Button or lever.
- a similar double-acting cylinder is provided in the actuator assembly as described above.
- the two working spaces via the or each connecting line with each other and with the pump or when the corresponding line is unlocked are connectable to the reservoir, and its work spaces alternate from one Supply unit can be fed with working fluid is structurally special given simple solution to specifically manual operation and emergency operation to simplify that not for different volumes Hydraulic medium in the opposing working spaces of the working cylinder arrangement must be prepared.
- the supply unit contains a reversible pump, the two outputs of which connected to check valves that can be unlocked via the other outlet are, with both sides of the reversible pump with each other via a shuttle valve and are connected to a reservoir for the working fluid.
- a sensor for the vehicle inclination is provided and is connected to the control unit, can be used to control the switching valve in If the stop function takes into account all actuation or holding forces in Connection with the orientation of the vehicle.
- a sensor for the movement of the pivotable part of the vehicle and connected to the control unit can also be a changing moment on the moving path along the way Part are taken into account, for example, from changes in the load on the vehicle part or by hitting an obstacle.
- an im Control unit stored program which depends on the actuation a queried control element to stop the movement of the Part of the vehicle and possibly also at least the inclination of the vehicle, preferably also the opening angle of the pivotable part and possibly also that Pressure curve in the system, a control signal for, among other things, the switching valve is generated.
- the program control enables a wide variety of functions to be implemented possible.
- the control unit is advantageously program-controlled also the normal actuation control, i.e. asks controls such as buttons, buttons, handles on doors, vehicle flaps or the like Accordingly, it not only controls the switching valve, but also the supply system for the working fluid, especially the reversible pump and all necessary Valves and other components.
- the program can also be designed to do this that it is the rapid, essentially resistance-free throwing of the door, the flap or the like.
- the impulse to start this special function can be performed by querying and recognizing a change in route on the displacement or angle sensor or the actuation of the pawl it inside or outside, a switch, button or similar on the moving component be given yourself.
- the rapid increase in pressure due to manual Initiation of the movement can at most by the system pressure sensor to the Control unit must be reported and the connection released. Or the Movement of the working fluid in its circuit is monitored and faster Increased movement can be used as a detection signal for the control unit become.
- the shows Drawing figure a circuit diagram of a hydraulic system according to the invention for for example an automatic door drive for motor vehicles.
- Movable vehicle part is about an axis of rotation 2 by means of, for example of a uniform double-acting hydraulic working cylinder 3 in opening and closing direction movable. These movements are caused by the loading of the two equally large work rooms 4 and 5, which provide volume compensation make avoidable between the two sides of the working cylinder 3 with Hydraulic oil causes, preferably the control of the work rooms 4 and 5 via a electronic control unit (not shown) is controlled.
- This Control unit asks, either by a stored or changeable stored in a memory Program or according to a fixed circuit, on the one hand a signal line from an operating element and also controls according to the stored Program or the predefined circuit on the one hand a subsequent valve and line arrangement to be explained in more detail, on the other hand Hydraulic unit, especially the motor of a reversible pump 6.
- the two sides the pump 6 are in turn on the one hand via a shuttle valve 7 with the tank 8 connected for the hydraulic oil, on the other hand over from the opposite Side via lines 9 unlockable check valves 10 with the working cylinder 3.
- a connecting line between the two sides of the pump 6 is one Changeover valve 12 is used, via which the line under pressure in each case a proportional pressure valve 13 for limiting the system pressure with the tank 8 connected is.
- a pressure sensor (not shown) connected, which is also connected to the control unit stands, as well as at least one sensor for the vehicle inclination and a displacement sensor for the movement of the door 1.
- a linear Working cylinder 3 coupled displacement sensor could also be a rotary sensor on the Axis of rotation 2 or generally any sensor arrangement can be provided, which one Allows statement about the opening angle of door 1.
- the check valves 18, 19 are spring-loaded valves that are oriented in opposite directions.
- the blocking or opening direction is selected such that the valves 18, 19 in the direction of the connecting line Open 14 or 15 on the opposite valve.
- the typically completely conventional check valves 20, 21 the opposite is true, i.e. that these valves 20, 21 from the connecting line 14, 15 to each opposite valve are blocked.
- the control unit stored program detects a quick manual movement of the door, for example manual throwing is desired, the control unit prevents this Closing the switching valve 23 from the beginning. Also the rapid increase in pressure, determined by one of the system's pressure sensors or the detection of the Movement of the hydraulic oil can cause the switching valve 23 to remain open, whereby then the essentially free pushing of the hydraulic oil from one Work room 4, 5 in the other and thus largely from hydraulic influence free movement of door 1 is enabled.
- the check valves 10 block the Connection between working cylinder arrangement 3 and tank 8, so that the hydraulic medium over the connecting lines 16, 17 and 22 only between the opposite Workrooms 4, 5 can be moved. This shifting is - as explained above - via the bias valve 24 in connection with the Switch valve 23 affects.
