Definitions

  • the invention relates to a door actuation system for a motor vehicle, comprising at least two hydraulic door lock actuators which can be activated via a door handle and a hydraulic Matverriegelungs- or Mosentriegelungs adopted associated with at least the two Schoschbetuschists promoteden, the Schoverriegelungs- or Mosentriegelungs acquired connected via a main line with at least one of the Mitschbetuschists promoteden is off, and a branch line from the main line to the other door lock or door unlocking at a Y-branch off / turns / branched off.
  • Door actuation systems are also understood to mean systems which also actuate flaps or covers or hoods of vehicles, for example hoods, trunk lids, trunk lids or doors of a general nature.
  • a branch is understood to mean a branch, which may also be designed as a switch, in order to distribute fluids such as liquids, in particular hydraulic fluids, such as oil, from one or more delivery devices to a receiving device or a plurality of receiving devices.
  • fluids such as liquids, in particular hydraulic fluids, such as oil
  • a typical example of this is a vehicle door in which a door closing module / closing module is actuated by both an inner and an outer door handle / door lever to open the door.
  • Hydraulic door operations are already known prior art, such as from the DE 199 49 037 A1 , Also the EP 1 273 744 A2 and the DE 102 28 978 B4 are basically in this area.
  • Locks for a door of a motor vehicle are also from the DE 199 49 037 A1 known. There it is disclosed that a door lock can be arranged on a door of a motor vehicle, which is coupled to a arranged on the door door handle to open the door lock, wherein the door handle is fluidly coupled to the door lock. Under a fluidic coupling is understood there a pneumatic or hydraulic actuation. It is disclosed that pneumatic or hydraulic couplings are realized.
  • a hydraulically operated door lock is further in the US 2298776 disclosed.
  • Devices for locking and unlocking door locks, using hydraulic devices, are also the US 4541258 refer to.
  • the DE 10 2004 037 299 A1 further discloses a door operating device with a vehicle door with an adjustably mounted door handle, with a door lock, with a motion-transmitting transmission element between the adjustable door handle and a locking device of the door lock, and with a securing device which prevents an unlocking position opening the door lock in an accidental displacement tendency of the door handle.
  • the transmission element has a closed transmission medium system which contains a transmission medium which comprises the transmission medium system a flexible, tubular transmission line, in the line course a line narrowing throttle is arranged so that a volume-displacement element is arranged on each side of the transmission line whose volumes filled with transmission medium are connected to each other through the transmission line containing the throttle and of which at least one of its sliding part is connected directly or indirectly in terms of movement with the door handle.
  • EP 0 936 102 A1 discloses an actuator using hydraulic elements, but for a locking device on a vehicle seat.
  • Locking and locking systems for doors or flaps are also from the pamphlets EP 1 273 744 A2 and DE 102 28 978 B4 disclosed. There are also disclosed special circuit diagrams for driving a slave cylinder by multiple master cylinder.
  • a shuttle valve is arranged in the Y branch to block either the main line or the secondary line and to block one of the door lock or door unlocking devices from the door lock operating device.
  • each door lock operating device is associated with a door lever or a door handle to trigger movement. This can be effected by manual force opening the door.
  • An advantageous embodiment is also characterized in that the shuttle valve is designed to be operated manually or automatically, such as electrically and / or magnetically.
  • At least one of the elements as a door lock operating device and door lock locking device or door lock unlocking device contains a pressure space volume-changing rolling diaphragm. Especially such rolling membranes allow a long life of the door operating system.
  • each door actuator and door lock or lock release means comprises a housing and a relatively movable piston, whereby the hydraulic system can be kept simple and efficient.
  • the piston of the door lock or door unlocking device acts on a latch of a closing module.
  • the invention relates to a hydraulic Matver- or unlocking, in which by two or more independent lock operations, such as a door lever or a door handle, or more door lever or more door handles can be operated by means of hydraulics on the closing module.
  • a typical example is a vehicle door in which both through the inner as well as through the outer door handle the closing module is operated to open the door.
  • the known solutions are based on two or more independent hydraulic lines, each connecting a lock operation with the closing module.
  • the independent hydraulic operation unfortunately caused in St. d. T. two complete hydraulic lines in which a cylinder of a lock operation and a cylinder in the lock module is required per line.
  • the invention intervenes successfully to reduce the number of components. It is therefore proposed a direct connection of the hydraulic lines in the form of a Y-circuit or the use of a shuttle valve. With a shuttle valve, the other actuating cylinders are hydraulically shut off. The total effort is significantly reduced.
  • FIG. 1 a first embodiment of a door actuation system 1 according to the invention is shown.
  • the door operating system has two hydraulic door lock actuators 2.
  • the door lock actuators 2 are basically designed as a hydraulic cylinder.
  • a door lock or door unlocking device 7 is activated.
  • a comparable door operating system 1 is also the FIG. 2 can be seen, but there, unlike in the embodiment according to the FIG. 1 , in the Y-branch 5, a valve 8, namely a shuttle valve 9 is included, which releases either the leading to the door lock actuator 2 main line branch or leading to the other door lock actuator bypass line branch, or shuts off.
