Definitions

  • the invention relates to a motor vehicle door lock, with a locking device, at least one actuating element and a locking mechanism, and with a coupling unit between the actuating element and the locking mechanism, wherein the locked in position "locking" locking device can be unlocked by a first stroke (Entriegelungshub) of the actuating element and the locking mechanism is to be opened by a second stroke (opening stroke) of the actuating element.
  • Such a motor vehicle door lock is exemplified in the DE 39 08 183 C5 presented.
  • a clutch lever connected to the clutch lever is provided, which is tensioned by the first stroke or Entriegelungshub.
  • the clutch lever can be moved under the influence of the aforementioned clutch lever spring from a disengaged position to a Einkupplungs ein.
  • the locking mechanism can be opened by the second or opening stroke of the actuating element.
  • the actuating element in the present case is an internal operating lever. This has proven itself in principle.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock so that a structurally simple design is realized with a cost-effective design.
  • a generic motor vehicle door lock in the context of the invention is characterized in that the locking device has a coupling unit directly acting on the drive element.
  • the locking device ensures that the motor vehicle door lock as a whole occupies at least the positions "locked” and “unlocked”.
  • the interposed between the actuator and the locking mechanism clutch unit in its disengaged position for idling of the actuating element relative to the locking mechanism. This is the usual functionality in the "locked” position.
  • the coupling unit is in its engaged position, a continuous mechanical connection between the actuating element and the locking mechanism is provided. That is, manipulation of the actuator cause the coupling unit works on the locking mechanism and can open this.
  • the locking mechanism has a catch and pawl, the latter interacting with a release lever.
  • the coupling unit now operates the release lever cooperating with the locking mechanism in this position (engaged position of the coupling unit or "unlocked") in such a way that the locking mechanism is opened.
  • the actuator may basically be an internal operating lever or an external operating lever.
  • the drive device or locking device consists essentially of a drive motor and the drive element together.
  • the drive element in turn interacts with the coupling unit, directly and without intermediate elements or levers.
  • Most of the drive element and the actuator are coaxially and arranged in parallel planes to each other.
  • the drive device or locking device and the coupling unit are placed level with each other to ensure a simple interaction between the two aforementioned elements.
  • the drive device has an actuating contour interacting with an actuation pin on the coupling unit.
  • the coupling unit is designed as at least two-armed clutch lever with release lever and Betjanistshebelarm.
  • the Betjanshebelarm is preferably equipped with the aforementioned actuating pin, which is acted upon by the actuating contour on the drive device or locking device.
  • the aforementioned actuating contour is usually found on a drive pulley of the drive device as a drive element.
  • this drive disc combs advantageous a drive screw, which is driven by a motor. In this way, the drive pulley of the drive device can perform clockwise and counterclockwise rotations.
  • the clutch unit or the realized at this point clutch lever is applied directly.
  • the clutch unit or the realized at this point clutch lever is applied directly.
  • the actuating contour is advantageously formed in two parts with free surface and actuating surface.
  • this movement corresponds to the fact that the clutch lever is transferred, for example, from the unlocked to the locked position.
  • a clockwise rotation of the drive disc may correspond.
  • the actuating element is acted on by a first stroke.
  • the actuating element ensures that the coupling unit leaves its formerly disengaged position (locking position) in comparison to the locking mechanism and is transferred to the engaged position.
  • the coupling unit advantageously has a driving pin engaging in an actuating recess of the actuating element.
  • the first stroke or Entriegelungshub now corresponds to the driving pin of the coupling unit or the clutch lever abuts an edge of the actuating recess of the actuating element respectively the actuating lever, in such a way that the clutch lever is transferred from its disengaged to the engaged position.
  • the drive or the drive means is moved and resumes its original position, which corresponds to the position "unlocked”.
  • the coupling unit is (again) in operative connection with the locking mechanism or its trigger lever arm is pivoted so that it strikes at the next or second stroke or opening stroke of the release lever respectively interacts with this to open the locking mechanism as a whole. That is, the second or opening stroke ensures that with the help of the coupling unit of the release lever lifts the pawl of the catch, so that this spring takes its open position.
  • the drive device or locking device works directly on the clutch lever and additional intermediate levers are unnecessary.
  • the said clutch lever can be operated both electromechanically by means of the drive means and manually in case of failure of the drive means by means of the actuating element. Because the interaction between the actuating element respectively actuating lever and the clutch lever is accomplished via the engaging in the actuating recess of the actuating element driving pin of the coupling unit. This is basically independent of an actuation of the coupling unit or of the clutch lever with the aid of the drive device in which the actuating pin on the clutch unit interacts with the actuating contour on the drive pulley or the drive device.
  • a motor vehicle door lock which is equipped with a conventional locking mechanism 1, 2.
  • the ratchet 1, 2 is composed of a rotary latch 1 and a pawl 2 cooperating therewith.
  • a release lever 3 is realized, which lifts the pawl 2 to open the locking mechanism 1, 2, so that the catch 1 can open spring-assisted.
  • the catch 1, the pawl 2 and the release lever 3 are each in comparison to the plane after Fig. 1 arranged perpendicular thereto, namely rotatable about a common axis A.
  • the other essential components of the motor vehicle door lock that is a locking device 4, 5, 6, an actuating element 7 and a coupling unit 8 in or parallel to the plane of the drawing after Fig. 1 to 3 placed.
  • the actuator 7 is in the context of an internal operating lever, although here also an external operating lever or a main operating lever can be used.
  • the drive device or locking device 4, 5, 6 is composed in detail of a drive motor or electric motor 6, a drive worm 5 and a drive pulley 4 or a drive element 4 together.
  • the drive worm 5 meshes with the drive pulley 4, so that the drive pulley 4 can perform rotational movements in a clockwise and counterclockwise direction. In the embodiment and not limiting the drive pulley 4 only rotates clockwise.
  • the drive pulley 4 and the actuating element 7 and the inner actuating lever 7 are coaxially mounted on a common axis B in a housing part 9, preferably the lock cover. Parallel to the axis B there is a further axis C, which serves for the storage of the coupling unit or the clutch lever 8.
  • a further axis C which serves for the storage of the coupling unit or the clutch lever 8.
  • the coupling unit 8 and the clutch lever 8 is at least two armed with Ausletteshebelarm 8a and 8 Betreli Trentshebelarm equipped.
  • the clutch lever 8 still has two more arms, but in the present case are not of interest.
  • the in the Fig. 4 shown drive pulley 4 and the drive means 4, 5, 6 in total is equipped with an actuating contour 10.
  • the actuating contour 10 is formed in two parts and has an open space 10a and an actuating surface 10b.
  • the actuating contour 10 interacts with an actuating pin 11 on the coupling unit 8.
  • the actuating pin 11 lies in the locked position Fig. 2 on the actuating surface 10b, whereas in the unlocked position Fig. 3 the actuating pin 11 can perform a movement relative to the free surface 10a.
  • the operation is as follows.
  • this first stroke is also called unlocking stroke.
  • the coupling unit or the clutch lever 8 is equipped for this purpose with a driving pin 12.
  • the driving pin 12 engages in an actuating recess 13 in the actuating element or the inner actuating lever 7, which is arranged above the coupling lever 8 on the common axis B.
