Definitions

  • the invention relates to a motor vehicle door lock, with at least one locking mechanism with essentially a catch with a main catch and optionally a latch for an incident pawl, with a cooperating with the catch bolt, and with an end stop for the locking mechanism to limit an overstroke of the catch when closing of the locking mechanism.
  • a door belonging to the motor vehicle door lock can be forced into an associated opening of a motor vehicle body by means of forcibly existing elasticities, for example of a circumferential door rubber seal, beyond the main locking position.
  • This can be done both manually by an operator and also by a motor, caused for example by a closing aid. Both procedures correspond to the above-mentioned overtravel for the catch. That is, the engaging in the inlet mouth of the catch locking bolt moves the catch in this process beyond the position belonging to the main branch.
  • the rotary latch or the locking mechanism is assigned to the end stop.
  • DE 199 42 360 C2 describes such a motor vehicle door lock which has a closing aid for the rotary latch.
  • the closing aid has a.
  • a pivotally mounted closing pawl is realized.
  • the rocker With the aid of an electromotive drive, the rocker is driven by the reversing member and the closing pawl until the already mentioned overstroke is reached.
  • the pawl may enter the main catch of the rotary latch while an associated crank mechanism of the electric motor drive has reached its top dead center.
  • the Um Kunststoffglied proposes to a housing-side stop or end stop. Details of the end stop remain open.
  • the friction brake is characterized by a in formed an oval recess of the rotary latch engaging oval-shaped component, wherein the maximum diameter of the component is equal to the minimum diameter of the recess. Also in this case, a structurally complex design is pursued.
  • the invention is based on the technical problem of further developing a motor vehicle door lock of the embodiment described above such that, with a simple construction in the course of closing the locking mechanism, a significant reduction of the impact noise when running onto the end stop is achieved.
  • the brake wedge in connection with the end stop can be realized constructionally without problems.
  • End stop and brake wedge may for example be made in one piece. Then an embodiment made of plastic has proven itself.
  • the brake wedge is preferably upstream of the end stop in the closing direction of the rotary latch (or the transmission member) and, as it were, tapers the closing path.
  • the brake wedge of a sound-absorbing or -mindernden material, eg. As plastic or has a sheath of a sound-absorbing or -mindernden material such as plastic.
  • the brake wedge can be arranged on a lock case and / or on a lock housing. In most cases, it has been proven to mold the brake wedge to the lock housing, because this is usually made of plastic. This is advantageous in terms of manufacturing technology.
  • the brake wedge can also be attached to the lock case, wherein the lock case is usually made of metal and has a U-shaped cross-section, with the rotary latch and the pawl are regularly mounted on its U-base.
  • the invention provides that the catch additionally has a buffer pocket and this buffer pocket in the closing direction of the catch is assigned its own buffer stop on the lock case for impact reduction during the closing process.
  • the buffer stop can also be provided on the lock case and / or the lock housing.
  • the buffer pocket still has a cooperating with the buffer stop bulge in order to optimize a reduction of the impact and in this respect to support the wedge braking effect.
  • Fig. 1 shows a motor vehicle door lock according to the invention schematically, reduced to rotary latch and pawl, which are in the main latching position and
  • Fig. 2 shows a detail of a lock case with catch, end stop and brake wedge, buffer pocket and buffer stop.
  • a motor vehicle door lock is shown, which is composed of a locking mechanism consisting essentially of a catch 1 with main catch 2 and possibly pre-catch 3 and a pawl 4.
  • a locking mechanism consisting essentially of a catch 1 with main catch 2 and possibly pre-catch 3 and a pawl 4.
  • an inlet mouth 5 for a cooperating with the catch 1 and not shown locking bolt.
  • a transmission member connected to the rotary catch 1 strikes the end stop and thus ensures that the rotary latch 1 experiences a noise-reducing braking when the main locking position is reached.
  • the Endan ⁇ shock 6 is usually arranged in the lock case 7 and consequently - like this - made of metal.
  • an overstroke Ü of the rotary latch 1 when closing the locking mechanism 1, 4 is limited. This overstroke Ü is indicated in FIG. 1.
  • the end stop 6 is a
  • Brake wedge 8 assigned. This serves for noise-reducing braking of the
  • Rotary latch 1 in the overstroke when approaching the end stop 6.
  • Brake wedge 8 is the end stop 6 upstream in the closing direction of the rotary latch 1 and consists of a noise-reducing material, eg. B.
  • the rotary latch 1 has a buffer pocket 9.
  • This buffer bag 9 is usually provided as in a plastic casing 13 of the catch 1
  • the buffer pocket 9 is associated with the buffer stop 10 in the closing direction S of the rotary latch 1.
  • the buffer stop 10 can also be molded onto the lock housing 12.
  • the buffer stop 10 in conjunction with the buffer pocket 9 ensures that an impact reduction of the rotary latch 1 takes place during the closing operation.
  • a cooperating with the buffer stop 10 bulge 11 is realized, which is arranged in the main latching position of the rotary latch 1 between the buffer pocket 9 and the buffer stop 10 (see Fig. 1).
  • the operation is as follows. Once the pawl 4 has left the pre-restraint 3 of the catch 1, because it is rotated clockwise about the entering in the inlet mouth 5 locking pin about its axis 15 in FIG. 1, the catch 1 runs shortly before reaching the main catch 2 against the brake wedge 8.
  • the oblique brake wedge 8 ensures that an edge 14 of the rotary latch 1 increasingly experiences a wedge effect with respect to the axis of rotation 15 of the rotary latch 1 and as a result thereof the rotary latch 1 is braked.
  • the bulge 11 abuts against the buffer stop 10. If an electric motor drive for the rotary latch 1 now ensures that the rotary latch 1 completes the overtravel Ü or if this is manually caused by an operator, then the buffer pocket 9 arranged in the closing direction S in front of the bulge 11 or the slot in the plastic casing 13 of FIG Rotary latch 1 sure that this overrun Ü is allowed, because the bulge 11 can escape elastically into the buffer pocket 9.
  • the brake wedge 8 permits such movements of the rotary latch 1. This naturally increases its wedge effect.
  • the overstroke is additionally limited if the bulge 11 is completely immersed in the buffer pocket 9. Because then every other way in a material deformation of the bulge 11 is implemented.
  • an associated spring constant of the brake wedge 8 as well as of the aggregate of bulge 11 and buffer pocket 9 increases strongly progressively. In any case, a particularly noise-reduced braking of the rotary latch 1 in the overstroke range in the course of running onto the end stop 6 is thereby achieved. This is possible with structurally simple and inexpensive means.

Abstract

L'invention concerne une serrure de portière de véhicule automobile comportant un loquet rotatif (1) et un cliquet (4), une butée de fin de course (6) étant associée au loquet rotatif (1) pour empêcher un dépassement de course lors du processus de fermeture. Un taquet de freinage (8), associé à la butée de fin de course (6), est prévu pour freiner le loquet rotatif (1) dans la zone du dépassement de course, de manière à atténuer le bruit engendré lors de l'entrée en contact avec la butée de fin de course (6).
