Definitions

  • the invention relates to a motor vehicle door lock, in particular servo lock, with a locking mechanism consisting essentially of a catch and a pawl, and having a drive with at least two levers for closing and opening the catch, wherein the first lever is designed as a closing lever and in a first setting direction of the Actuator pulls on the catch, and wherein the second lever is designed as an opening lever and operates in a second actuating direction of the drive on the pawl opening.
  • Motor vehicle door locks and in particular servo locks are typically equipped with at least one drive.
  • separate drives are often realized on the one hand the closing and on the other hand the opening of the locking, which is technologically complex and also leads to increased costs.

  • the first output element acts in the first direction of an electric motor as an opening aid on the associated pawl.
  • the second output element acts in the first running direction opposite second direction of the electric motor as a closing aid on the catch. In this way, a total of space-saving trained motor vehicle door lock is to be made available. This succeeds partly insofar as only a single electric motor is used.
  • the known teaching relies on a relatively complicated kinematics.
  • a transmission is provided for this purpose in addition to the electric motor.
  • the gearbox has a worm on the shaft of the motor, which meshes with a worm wheel.
  • two more gears realized. This results in a mechanically complex structure, which is also susceptible to interference due to the large number of transmission elements.
  • the power transmission is limited.
  • a generic motor vehicle door lock in the invention is characterized in that the drive is designed as a spindle drive with spindle and spindle nut mounted thereon, wherein the spindle nut, starting from a neutral position, either acts on the closing lever or the opening lever.
  • the spindle drive has a single motor, which drives the spindle via a gearbox.
  • the transmission according to the invention generally has only one gear wheel.
  • This is advantageously a worm wheel mounted on the spindle, which is driven by a worm on the drive side of the single motor or electric motor.

D. h., The two levers can be stored as well as the locking mechanism in the lock case in question and are pivoted to their operation in or parallel to the respective Gesperreebene.
  • the linearly movable spindle nut In order to initiate this pivoting movement, it is only necessary according to the invention for the linearly movable spindle nut, starting from a neutral position of the spindle drive, to act on either the closing lever or the opening lever. As a result of this design, the spindle nut furthermore engages in each end of the respective lever, if necessary Even large torques are generated. As a result, the spindle drive in the motor vehicle door lock according to the invention is able, without any constraint, to also act on increased closing forces via the closing lever on the rotary latch.
  • the weight of the motor vehicle door lock according to the invention can also be set particularly low.
  • the circumstance contributes to the fact that advantageously not only the spindle and the worm wheel are designed as plastic components or plastic injection-molded part. But also the spindle nut can be designed as a plastic component or plastic injection molded part. As a result, on the one hand a low friction of the spindle nut made of plastic on the spindle also made of plastic available and can be on the other hand produce the said components with very low production costs. Also, the weight is low.

  • the opening contour is usually provided below the spindle on the spindle nut.
  • Such a rather off-axis arrangement and expression of the opening contour below the spindle is not a problem, because typically much lower forces must be expended for the opening process and the lifting of the pawl of the catch of the catch, as is the case for Zuteil.
  • the procedure is usually that the opening lever in question rests in the neutral position on the opening contour.
  • a mechanical contact between the opening lever and the opening contour during an opening operation is given.
  • the closing lever in the neutral position is spaced from the Zuziehkontur.
  • the closing lever engages directly or indirectly on a stop of the rotary latch and ensures the required to Zuziehhik the locking mechanism pivotal movement of the catch.
  • a motor vehicle door lock is provided, which can be produced with low production costs, while it can be easily and compactly constructed.
  • only a few components are used, so that functional impairments can be excluded.
  • the power transmission from the spindle drive, in particular to the closing lever is particularly advantageous, so that even large required Zuzieh mechanism can be made available to the catch.
