Definitions
- the invention relates to an arrangement for hydraulic actuation of a Rear cover, a cover flap or the like on a vehicle, with at least a double-acting hydraulic working cylinder, on the one hand on the Vehicle and on the other hand is hinged to the cover flap and its Workrooms each with a check valve with one side of each switchable pressure source are connected, the two check valves have a mutual unlocking device and each of the work rooms parallel to the non-return valves via a control valve in the tank Bias valve is kept at a certain pressure level.
- Such arrangements are known and enable, for example, the automatic actuation of vehicle doors, bonnets, maintenance flaps or also of cover flaps of the trunk or of a folding roof Space.
- the preload valve enables the cover flap to move in a controlled manner in this state, for example, by hand, such as an emergency closing to allow against a force specified by the preload valve.
- a disadvantage of the known arrangement mentioned of the type mentioned especially the fact that the described emergency operation only in context with a volume-balanced working cylinder is possible because it otherwise problems with the removal or supply of hydraulic medium to the piston or rod-side working space there.
- a simple shutdown of the excess volume ejected from the respective work area into the Tank would still be possible - but there are problems with it in an emergency unpressurized supply of hydraulic medium to the other work area, because for the application in vehicles uses very thin, flexible cables which, on the other hand, are also due to the crowded accommodation options are relatively long, so that the absorbing work area is at least partially filled with outgassing air. This then leads that after dropping the manually operated cover flap it is undefined can fall back and cause damage and injury.
- the object of the present invention is to provide a known arrangement of the Improve the type described above so that the disadvantages described to be avoided and that in particular in a simple and safe manner Emergency actuation of the cover flap also on the usual, on the piston and rod side different volumes of the working cylinders having working spaces becomes possible.
- This task is performed in accordance with an arrangement of the type mentioned solved the invention in that between at least one work space, preferably the piston-side working space, and the associated unlockable Check valve a separate suction line leading to the tank opens into which a non-return valve opens towards the work area is inserted. If there is a failure of the hydraulic working pressure furthermore a simple and safe emergency operation of the cover flap, for example possible by hand. With the working cylinder pulled out by hand the rod-side workspace volume is pushed into the tank, the missing differential volume is sucked out of the tank via the check valve becomes. Since no further hydraulic elements such as Valves, nozzles, etc.
- the suction line with the check valve also be provided on the rod side of the working cylinder and the unimpeded suction of hydraulic medium when manually closing the Cover flap or the like. And the subsequent securing against unintentional Ensure press on. This is supportive, especially in the case of opening or with appropriate strength gas springs od. Like., Guarantees that even if the operating hydraulics fail Cover flap or the like is held in the manually set position.
- the suction and safety function for manual opening and closing by providing a suction line with a check valve on both the Rod as well as the piston side of the working cylinder is conceivable, alternatively also the connection of a suction line with a check valve alternately one of the lines to the working cylinder via a changeover valve.
- the Suction line between the respective work area and the closest one hydraulic component opens. So that is immediate and unimpeded Suction of hydraulic medium from the tank, regardless of the Equipment of the automatic actuation system and its optimal design on their function in manual operation.
- Fig. 1 shows a schematic arrangement according to the present Invention in a vehicle
- Fig. 2 shows a schematic hydraulic Circuit diagram of an arrangement according to the invention.
- FIG. 1 The arrangement shown in Fig. 1 for hydraulic actuation of a Cover flap, a boot lid or other movable vehicle part 1 on a vehicle 2 has at least one double-acting hydraulic Working cylinder 3 on the one hand on the vehicle 2 and on the other the cover flap 1 is articulated.
- the workrooms not shown here of the working cylinder 3 are via lines 4, 5 with a hydraulic unit 6 connected, which via a connecting line 7 with the electrical Vehicle 2 electrical system is connected.
- movable hydraulic unit 6 may require the articulation of the working cylinder 3 on the vehicle and / or cover flap side also indirectly via levers, hinge arrangements or the like take place, the working cylinder 3 also being fixed relative to the vehicle 2 could be mounted.
- the 2 is the combination of hydraulic unit 6 and Lines 4, 5 connected cylinder 3 shown in more detail.
- the two working spaces 8, 9 of the working cylinder 3 are via the lines 4, 5 and each with a check valve 10, 11 arranged in the hydraulic unit 6 one side each of a switchable pressure source 12 (formed here Pump including drive motor) in connection.
- the two check valves 10, 11 are connected via lines 13, 14 and can be unlocked from each other. over one bias valve 15, 16 each, the two working spaces 8, 9 are parallel to the check valves 10, 11 in the tank 17 as soon as an adjustable Pressure levels are reached or exceeded.
- the preload valves 15, 16 are via lines 18, 19 and the pump side in front of the check valves 10, 11 prevailing pressure can be shut off hydraulically.
- the function of the arrangement shown is as in FIG. 2 illustrated explained.
- the Working cylinder 3 off or on.
- the motor of the pump of the pressure source 12 is energized, the pump runs and supplies pressure medium via the check valves 10 or 11 in the piston-side working space 8 or the rod-side Working room 9. This is on the same side via lines 18 and 19 such as the bias valve 15 or 16 controlled.
- the pressure in the work area 8 or 9 can be up to Build the required value.
- the cover flap 1 (Fig. 1) opens or closes hydraulically up to the stop in the working cylinder 3.
- the volume of the rod-side work space 9 flows when opening via the line 14 hydraulically controlled check valve 11 and the shuttle valve 20 in the tank 16 off.
- the hydraulic system delivers the total pressure relief valve 21 or 22 adjustable force.
- the pump runs until the cover flap 1 is open and is then switched off.
- a cover flap 1 according to FIG. 1 could be the inventive arrangement of course also for the actuation of vertical in the closed state
- Tailgates can be used for example a station wagon or a bus.
- Other application examples would be e.g. Vehicle doors, maintenance or ventilation flaps and the like.
