Definitions

  • the invention relates to a motor vehicle door lock, with at least one rotary latch with a pre-catch, a main catch and optionally an overstroke, and with at least one motion damper.
  • motor vehicle door locks have a housing mostly made of plastic and in addition a lock case made of metal, which provides for the storage of a locking mechanism of substantially the catch and a pawl.
  • the locking mechanism of the motor vehicle door lock typically interacts with a locking bolt on, for example, a B pillar of a motor vehicle body.
  • the motor vehicle door lock is usually arranged inside a motor vehicle door, so that a total of a motor vehicle door lock is provided in this way.
  • the rotary latch usually interacts with the locking bolt in a motor vehicle door lock.
  • the catch is equipped with a receptacle, a so-called inlet mouth.
  • the motor vehicle door lock When closing the motor vehicle door, the motor vehicle door lock is guided towards the locking bolt, which then engages in the receptacle (inlet mouth) of the rotary latch, whereby a mostly horizontal rotational movement takes place.
  • the catch In order to prevent a re-emergence of the locking bolt in the closed state, the catch is additionally rotated so far that the pawl is incident and the locking pin is mainly no longer movable horizontally. When the locking pin and the catch have reached their locked position, further rotation of the catch is blocked by the pawl and optionally an overstroke stop.
  • the pre-locking position essentially serves to intercept the corresponding door or flap when it does not reach the main detent position when closing. That is, in the pre-ratcheting pitch, the rotary latch is consequently not completely closed, but an opening movement of the rotary latch by the pawl is already prevented. In contrast, in the main rest position, the rotary latch and with it the associated motor vehicle door is completely closed. Due to the interaction of all these components (rotary latch, locking pin, pawl) as a function of the respective closed position has been found again and again in practice that form disturbing impact and / or jerking noises during the opening and closing operation.
  • these disturbing noises may occur, for example, when the locking bolt enters the inlet mouth of the rotary latch and is held in its main locking position by the rotary latch, while on the other hand it must be ensured that the locking pawl cooperating with the rotary latch engages the locking catch Main rest area does not leave when the catch performs an overstroke in the course of their closing movement.
  • a possible solution in the generic DE 20 2005 020 452 U1 provides, for example, that the motor vehicle door lock is equipped with a motion damper, which ensures on the one hand that an effective limitation of the adjustment of the locking takes place and on the other, that thereby partially possible opening - or closing noises are minimized.
  • a similar approach is pursued in DE 20 2005 010 526 U1.
  • a motor vehicle door lock with a motion damper in which the motion damper has a deformable surface and also rolls in dampening both in the opening and closing direction of a locking mechanism. This is also trying here, especially during the opening and closing operation possible lock noise as well as possible to suppress.
  • a generic motor vehicle door lock is characterized in the context of the invention in that, depending on the rotational movement of the rotary latch, an overlapping surface is formed between the motion damper and the rotary latch to a defined and variable braking torque transmission. That is, depending on the rotational movement of the rotary latch, the braking torque can be adjusted. In other words, the changing overlap surface generates a rotation angle-dependent braking torque.
  • the overlap area is the common area of one hand, the catch and on the other hand, the motion damper.
  • the catch penetrates into the elastic motion damper in accordance with the overlap area.
  • the motion damper is elastically deformed and generates depending on the deformation reason (size of the overlap surface) a corresponding braking torque.
  • the larger the overlap area the larger the braking torque generally.
  • any contact of the movement damper, especially in the corresponding closed positions of the catch (pre-rest, main load and possibly the overstroke) causes the rotary latch can be controlled in their rotational movement. That is, it can be achieved a defined braking torque transmission in dependence on the respective closed position.
  • the motion damper according to the invention is designed as a rolling damper rotatably mounted in the lock case and / or lock housing.
  • the axis of the motion damper can be directly in or be integrally formed on the lock case or the lock housing in order to keep the manufacturing costs low.
  • the motion damper rolls depending on the closed position times more and less on an outer contour of the rotary latch with predetermined by the outer contour path-dependent overlap surface.
  • the overlap area in this context means - as I said - the area that arises when the rotary latch contacts its outer contour with the motion damper. This can, as will be shown later, also correspondingly deform depending on the closed position, depending on how strongly the rotary latch or the outer contour dips into the motion damper.
  • the outer contour further has a path-dependent distance to the axis of the motion damper at the edge.
  • the invention is based on the recognition that the greater the overlap area between the outer contour of the rotary latch interacting with the motion damper, the greater the braking torque transmission. For the individual closed positions, this means in detail that the catch experiences first in the pre-locking position (pre-rest) on the outer contour a maximum braking torque transmission and thus its full braking force through the overlapping surface.
  • the rotary latch continues to arrive in the main latching position (main latching), then in this case it experiences almost no braking torque transmission since almost no overlapping surface is formed in this closed position.
  • the braking force in the main load drops to almost zero, so that smooth closing, in particular a motor vehicle door, is made possible.
  • the maximum braking torque transmission is observed in the Vorrastsannon to decelerate the associated motor vehicle door while allowing a detent. After that, the braking torque drops to zero or almost zero until the main locking position.
  • overstroke If the catch continues to move into the overstroke (overstroke), it may partially experience a brake torque transfer on the outer contour through the overlap area, so that in this case the braking force can be used in part as needed.
  • An optional overrunning buffer usually provides additional braking.
  • the motion damper in this position usually does not come into contact with the rotary latch, so that there is no overlap area and thus no brake torque transmission.
  • the motion damper has at least one deformable surface to reliably dampen the movement of the catch. Because in that the motion damper is equipped with a deformable surface, a rolling is possible in contact with the outer contour of the rotary latch. In most cases, the motion damper is also made of an elastic material as a whole or has the already mentioned deformable surface made of the relevant elastic material. Because this deformable elastic material is able to implement the kinetic energy of the rotary latch in flexing work. That is, by the embodiment according to the invention a particularly effective damping of the rotary latch is achieved by an increased energy absorption due to the rotational flexing of the motion damper simultaneously.
  • the eligible elastic materials are mainly elastomeric materials. These include, for example, acrylonitrile butadiene rubber (NBR), ethylene propylene rubber (EPDM), styrene butadiene rubber (SBR), to name just a few.
  • NBR acrylonitrile butadiene rubber
  • EPDM ethylene propylene rubber
  • SBR styrene butadiene rubber
  • the motion damper is preferably cylindrical and thus favors perfect rotational movements and rolling.
  • the motion damper may also advantageously be a circular disc made of an elastomer, which can be equipped with a central bore, in which engages the mounted on the lock case and / or lock housing axis of rotation.
  • the rotary latch which is regularly made of metal, may have a jacket of a sound-absorbing or reducing material in order to additionally minimize the impact noise.
  • this Material may be a thermoplastic such as polyurethane, so that at this point also the noise is counteracted.
  • the motion damper depending on the individual closed positions provides a defined braking torque transmission available.
  • elastic deformation of the overlap surface results in a particularly effective absorption of the closing energy of the rotary latch.
  • disturbing locking noises are effectively damped in the individual closed positions, so that the comfort and noise behavior of a motor vehicle door lock are generally improved.
  • the main benefits are the main benefits.

  • the rotary latch 1 interacts with a locking pin, not shown, and the pawl.
  • the locking pin usually transfers the rotary latch 1 from its open position to the closed position (see Fig. 1), by he engages in an associated inlet mouth 8 and pivots the catch about its axis 9 in a clockwise direction.
  • the rotary latch 1 is equipped with a pre-catch 2 (FIG. 1B), a main catch 3 (FIG. 1C) and an over-lift 4 (FIG. 1D). Both the rotary latch 1 and the pawl, not shown, are each rotatable about respective axes, also not shown, stored in a lock case.
  • the lock case is usually also used as a base or storage for a rotation axis which rotatably receives a motion damper 5. Conceivable would be next to an injection mold and screw or rivet joints that connect the motion damper 5 with the lock case.
  • the motion damper 5 is formed in the embodiment and not restrictive cylindrical made of an elastic material.
  • an elastomer can be used here, as has already been explained in more detail above.
  • the motion damper 5 is preferably formed as an annular disc, which forms with its surface in dependence on the rotational movement of the rotary latch 1, an overlap surface 6 in contact with the rotary latch. Strictly speaking, a surface overlap of the motion damper 5 takes place or with an outer contour 7 of the rotary latch 1 instead (see Fig. 2).
  • a part of the rotary latch 1 must preferably be designed in an arc-shaped manner with a radius adapted to a diameter of the movement damper 5.
  • the surface of the motion damper 5 does not experience a complete overlap with the outer contour 7 of the rotary latch 1 in any of the closed positions, otherwise jamming occurs or adhesion of the two surfaces may arise.
