Definitions

  • Such arrangements are known and allow, for example, the automatic operation of vehicle doors, bonnets, maintenance flaps or also from cover flaps of the trunk or a folding top receiving Space.
  • the preload valve allows controlled further movement of the cover in this state, for example, by hand, such as an emergency closing to allow against a predetermined by the preload force.
  • the from the connections of the shuttle valve to the tank diverting pressure relief valves ensure compliance with a predetermined maximum pressure in the System.
  • a disadvantage of the cited known arrangement of the type mentioned is but the fact that in an emergency operation, the check valves closed are, so that the necessary strong operating forces in manual Opening and closing also cause very high pressures in the hydraulic system, which can not be removed via the closed check valves yes. Therefore threatens the damage, in particular the hinges of the cover flap, Boot lid od. Like., The hinges and also the controls.
  • Object of the present invention is to provide a known arrangement of initially described type to improve so that the disadvantages described be avoided and that in particular in a simple and secure way the Damage to the assembly during manual emergency operation of the cover flap can be avoided.
  • This object is according to an arrangement of the type mentioned in accordance the invention achieved in that between at least one working space and the associated pilot-operated check valve one parallel to the biasing valve leading to the tank, line attaches, in which the Druckbegrenzüngsventil is used. Due to the parallel arrangement of check valve and Pressure relief valve can also be closed by manual operation and therefore Check valve of the preset pressure of the pressure relief valve dismantled via this valve and the hydraulic fluid in the tank be canceled so that damage to the system and the mechanical Parts are largely prevented.
  • FIG. 1 shows a schematic arrangement according to the present invention Invention in a vehicle
  • Fig. 2 shows a schematic hydraulic Schematic of an inventive arrangement.
  • FIG. 1 The arrangement shown in Fig. 1 for the hydraulic actuation of a Cover flap, a trunk 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 work areas 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 electric On-board network of the vehicle 2 is in communication.
  • Fig. 2 the combination of hydraulic unit 6 and over the Lines 4, 5 connected working cylinder 3 shown in more detail.
  • the two working spaces 8, 9 of the working cylinder 3 are via the lines 4, 5 and one in the hydraulic unit 6 arranged check valve 10, 11 with each one side of a switchable pressure source 12 (here formed from Pump with drive motor) in connection.
  • the two check valves 10, 11 are connected via lines 13, 14 and mutually unlocked.
  • about one biasing valve 15, 16 are the two working spaces 8, 9 parallel to the check valves 10, 11 diverted into the tank 17, as soon as an adjustable Pressure levels is reached or exceeded.
  • the preload valves 15, 16 are via lines 18, 19 and the pump side before the check valves 10, 11 prevailing pressure hydraulically shut off.
  • FIG. 1 connecting line 7 which in Fig. 2 not is shown separately controls the motor of the pump of the pressure source 12 and a shuttle valve 20. Furthermore, about this connecting line 7 also For example, limit switches or other position controls signals to not provide further shown control units or the like.
  • the working cylinder 3 moves 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 and 11 in the piston-side working space 8 and the rod-side working space 9.
  • About the Lines 18 and 19 is on the same side as the respective flowed through Check valve lying biasing valve 15 or 16 controlled.
  • Of the Pressure in the working space 8 or 9 can be up to the required value build up.
  • the cover flap 1 (Fig. 1) opens or closes hydraulically to the stop in the working cylinder 3.
  • the volume of the rod-side working space 9 flows when opening via the hydraulically controlled via the line 14 Check valve 11 and the shuttle valve 20 into the tank 16 from. ever counterweight or counterforce on the cover flap 1 provides the hydraulic Overall, the adjustable pressure relief valve 21 or 22 force.
  • the Pump runs until the cover flap 1 is opened and is then switched off.
  • the motor of the pump When closing hydraulically, the motor of the pump is again the pressure source 12 energized, in which case now pressure medium via the check valve eleventh is promoted in the rod-side working space 9.
  • the lid 1 closes with an adjustable pressure relief valve 22 force. That from the piston-side working space 8 outflowing volume flows over the over the Line 13 open check valve 10 and the shuttle valve 20 in the tank 16 off.
  • the closing force can not be higher than the pressure relief valve 22 are set, which can be easily realized that the cover 1 can be stopped even if necessary by hand.
  • the Cover flap 1 is when stopping the hydraulic actuation by the held the biasing valves 15 and 16 set pressure.
  • the check valves 10 and 11 are closed, the pressure built up over the bias valves 15 or 16 and the pressure relief valves 25 and 26th be reduced.
  • the pressure relief valve 26 ensures the manual Opening the cover 1 with extension of the working cylinder 3, the prevention Damage to both the hydraulic and mechanical parts the actuator assembly and the vehicle parts themselves.
  • a cover flap 1 according to FIG. 1 (for example, on a trunk or the hood of a car) could the inventive arrangement
  • the inventive arrangement for example, also for the operation of vertical when closed Tailgates are used for example a station wagon or a bus.
  • Other application examples would be e.g. Vehicle doors, maintenance or ventilation flaps and more.
