Definitions

  • the invention relates to a motor vehicle door lock, with a closing / opening device with drive and transmission element, and with a lock, wherein the drive works with the interposition of the transmission element on the locking mechanism to pull this or open.
  • DE 101 40 385 A1 relates to a servo lock holder for a motor vehicle door lock.
  • a locking pin of the motor vehicle door lock is attached to an adjustable actuating rocker.
  • a drive for the actuating rocker is provided. The drive transfers the actuating rocker with the locking bolt and a locking bolt comprehensive the catch and thus an associated door from a prelocking position in an Endschbachhorn motor.
  • An additional locking lever ensures that the actuating rocker is held in this position during manual transfer of the door from the prelocking to the final closed position.
  • Such servo lock holders are basically used in all conceivable doors on a motor vehicle. Thus, not only an admission of side doors, but also of trunk flaps, tailgates or even hoods is conceivable and is included in the invention. With the aid of the closing aid or the servo lock holder realized in this way, the relevant door or vehicle door can now be displaced from the previously closed position into an end closed position against the resistance of, for example, a door seal. As a result, a possible quiet and low-power door closures is achieved.
  • a closing device is the subject of DE 198 28 040 B4. This is about a power-assisted closing device for doors, flaps, hoods or roofs of vehicles and in particular passenger cars in which a pivotable on impact element is arranged on a rotary latch.
  • the pawl interacting with the catch also has a pivotable stop member.
  • the two stop elements cooperate with a control disk during the opening or closing operation.
  • the control disk is part of an actuator, with the help of both an opening and closing operation can be effected.
  • the described drives and associated elements often build relatively bulky, so that one proceeds in practice regularly so that the drive is installed away from the locking mechanism and consequently an associated motor vehicle door lock in the relevant motor vehicle door or in a body. Movements of the electric drive are transmitted in this case by means of the transmission element to the locking mechanism.
  • the transmission element is typically a Bowden cable, although rods, cable drives, etc. can also be advantageously used at this point.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock so that it is possible to work with an optimized weight and cost-optimized drive with unchanged functionality.
  • a generic motor vehicle door lock in the invention is characterized in that the drive is designed to be variable in torque and the transmission element
  • the drive has a torque converter.
  • This torque converter is generally designed to provide a progressively increasing torque or a progressively increasing force on the output side as the drive path increases.
  • the torque converter with increasing drive path but also deliver a degressive decreasing torque or a corresponding degressively decreasing force output side.
  • the output-side torque or the corresponding force is used to act on the transmission element.
  • the said different interpretations can be advantageously realized in that the torque converter is designed to be interchangeable.
  • the drive path corresponds to a Zuziehweg.
  • This Zuziehweg begins in general in a Vorrastsannon the Gesperres.
  • taking this Vorraszin corresponds to the fact that usually the drive of the toggle device is started and ensures that the locking mechanism is transferred from its Vorraswolf in the main locking position.
  • the growing Zuziehweg also belongs to the transition from the Vorrastsannon in the main rest position in the example described. - In an alternative also possible opening device will proceed overall vice versa.
  • the torque converter as part of the drive ensures that with increasing drive path or Zuziehweg at a Zuzieh coupled and thus at the transition from the Vorraswolf in the main rest position according to the previously described example provided by the torque converter torque and thus the force or Tightening force increases progressively.
  • the locking mechanism is also tightened with increasing force so that, in particular, growing opposing forces associated with a compression of the door rubber seal can be overcome.
  • the torque converter used according to the invention is able to realize a power transmission of up to 4: 1.
  • the force provided by the electric motor on the output side can be progressively increased up to a factor of four via the drive path or closing path by the described torque conversion.
  • a torque wheel wall ler is in principle any conceivable gear arrangement possible and can be implemented according to the invention, for example, a planetary or spur gear.
  • the torque converter is designed as a cam connected to the drive.
  • a cam can be realized with low weight and constructively simple, so that in spite of the additional torque converter overall a significant overall cost and weight savings is observed.
  • such a cam can be easily replaced and thus the interchangeability of the torque converter
  • the drive is designed overall in the manner of a modular drive. That is, the cams connected to the drive can be selected and used depending on the desired torque curve.
  • the cam in question is typically driven by means of a worm connected to an output shaft of the engine.
  • the worm engages in a circumferential toothing of the cam.
  • the cam is advantageously equipped with a helical control contour. The increasing due to the spiral shape radius of the control contour is designed so that it increases from a center of the cam, starting in the direction of a circumference of the cam.
  • the transmission element is in turn connected at its one end to the cam disc or the control contour.
  • the other end of the transmission element acts on the other hand, the locking mechanism.
  • This design can be implemented particularly advantageously and simply in the event that the transmission element is a Bowden cable.
  • a Bowden cable is typically composed of a central soul and a shell enclosing the soul. The sheath is supported regularly at its two ends to abutments. This allows the soul to transmit forces to the shell.
  • According to the soul is now connected to the cam respectively the cam contour formed on the control contour. Since the control contour is equipped with a radius which grows spirally starting from the center, a torque which increases with the radius of the spiral control contour is applied to the end of the transmission element connected to the cam or the core of the Bowden.
  • This growing torque on the input side of the transmission element or the Bowden cable corresponds on the output side to a correspondingly progressively increasing force or closing force, by means of which, for example, the rotary latch is transferred from its pre-detent division into the main detent position.
  • the end of the transmission element or Bowden cable connected to the locking mechanism can work on a transmission lever, which in turn acts on the rotary latch via a drive pawl in a pulling-in sense, similar to that described in DE 20 2008 015 789 already mentioned at the beginning U1 is realized.
  • the locking end of the transmission element or Bowden cable can work directly on the catch in order to attract them in the described sense, that is to transfer in the example of the Vorrastsannon in the main latching position.
  • the torque converter is designed to be interchangeable.
  • the design is such that the control contour is connected via a plug connection or a comparable releasable connection with the cam.
  • the control contour can be easily adapted to the actual conditions, depending on the design and power requirement in the correspondingly formed motor vehicle door lock.
  • the drive is equipped with a spring store or can be equipped. With the help of this spring memory, for example, the closing movement can be supported. This is achieved inter alia by the fact that the drive the spring
  • the spring accumulator is a simple and inexpensive leg spring. Of course this is not mandatory.

  • the rotary latch 1 must perform about its axis of rotation 8 a movement in the indicated counterclockwise direction.
