Definitions

  • Motor vehicle lock in particular motor vehicle door lock
  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of the locking mechanism components, a rotary latch and a pawl, and with a latching element which is arranged in the engagement area between the two locking mechanism components and which is pivotably mounted on the rotary latch and/or the pawl for the most part in a locking mechanism plane.
  • Motor vehicle locks and in particular motor vehicle door locks, have been acoustically optimized for years in order to take into account the increasingly stringent requirements for noise behavior. In addition, the focus is on improvements in comfort.
  • the motor vehicle locks in question are, for example, motor vehicle door locks which, in principle, can also be used on motor vehicle hoods, motor vehicle tailgates, motor vehicle tank flaps, etc. This also includes motor vehicle locksmiths for seat locks, load locks, etc.
  • the engagement area between the rotary latch and the pawl as the two locking mechanism components has a decisive influence both on the acoustics and the haptics of such motor vehicle locksmiths and thus on the comfort during operation.
  • the engagement area can also be between two pawls in a multi-pawl locking mechanism. Then the engagement area refers to that between a so-called comfort pawl and a pawl.
  • the latching element has a guide extension that protrudes in relation to the level of the locking mechanism for additional axial and/or radial guidance.
  • the guide extension can be formed in one piece with the latching element, for example as an embossing. It is also possible in this connection to work with an additional element in the form of, for example, a separate push-through pin and/or to design this as part of a casing for the latching element.
  • the plastic sheathing that is provided anyway on a rotary latch is often used for axial guidance and securing of the latching element.
  • the plastic sheathing is extended into the area where the locking element is mounted, in the example on the rotary latch, and covers the area where it is mounted.
  • the latching element is axially secured with the aid of the plastic sheathing, so the bearing axis of the latching element cannot move axially.
  • the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that the latching element has a perfect axial securing feature.
  • the invention proposes in a generic motor vehicle lock and in particular a motor vehicle door lock that at least one locking component is equipped with an overlapping material of the same material that at least partially overlaps the locking element to secure the locking element axially.
  • the locking element can in principle be pivoted both on the rotary latch and on the pawl or on both locking mechanism components, specifically with respect to pivoting movements in the locking mechanism plane.
  • the level of the locking mechanism is spanned by the rotary latch and the at least one pawl.
  • the engagement area can also be present between two pawls in a multi-pawl locking mechanism, as has already been explained.
  • the engagement area is provided on the rotary latch and the latching element is pivotably mounted on the rotary latch as a relevant locking mechanism component.
  • the invention proposes covering the latching element at least partially with the same material on the locking component in question. It is particularly important that the overlap reaches and covers the engagement area of the latching element in the relevant locking mechanism component and thus ensures and can also ensure the desired axial securing of the position axis.
  • the cover is a cover of the same material as the ratchet component, ie the cover and the ratchet component are made of a matching material.
  • steel is used for the locking mechanism component.
  • the cover made of the same material is also made of steel, so that it is compared to that used in practice and in the state of the art Coverage in the form of the plastic sheathing, in contrast, achieves a significantly improved axial securing of the bearing axis of the locking element.
  • the covering is made of the same material in comparison to the associated locking mechanism component does not, of course, rule out the possibility of using different types of steel for the locking mechanism component and the covering.
  • the locking mechanism component in question is multi-layered with at least one core layer and a cover layer having the covering.
  • the core layer and the cover layer can each be manufactured and manufactured from steel. Nevertheless, there is the possibility of using a particularly tough steel for the core layer compared to the cover layer.
  • the term "same material" is to be interpreted broadly within the scope of the invention.
  • the core layer in question and the cover layer are each made of a metal.
  • the core layer is made of steel, while the cover or the cover layer can be made of another metal such as copper or brass.
  • different metal alloys are also conceivable for the core layer on the one hand and the cover layer on the other and are encompassed by the invention.
  • a covering that is not the same material and a corresponding cover layer made of plastic, for example, is ruled out according to the invention.
  • the covering layer and consequently also the cover layer have comparable material properties to the core layer, particularly with regard to strength and toughness, which must primarily control the tearing forces that occur, for example, to meet safety requirements or also in the event of a crash.
  • the locking element is properly secured axially and according to the invention, in contrast to the prior art, there is no (longer) risk that the cover layer or the covering will shear off, tear off or be damaged in any other way. This is where the main advantages can be seen.
  • the possibility of equipping the locking mechanism component in multiple layers with at least one core layer and a cover layer having the cover can be further developed in that the at least one core layer is provided between cover layers on both sides.
  • other layers in the sense of a multiple-layer structure of the locking component in question are of course also conceivable and are encompassed by the invention.
  • the invention also proceeds in such a way that the covering layer protrudes over the area of the core layer by the amount of the covering.
  • the overlap ensures that the engagement area between the locking mechanism component in question and the latching element is covered and the bearing axis that is formed thereby experiences the desired axial securing.
  • cover layer and the core layer from the same or different metal
  • the cover layer and the core layer are connected or coupled to one another by a forming process without additional material.
  • a forming process without additional material.
  • the individual layers are deformed together or subjected to the forming process described above.
  • This can be a so-called clinching or clinching.
  • the individual layers are coupled to one another by forming, for example by means of punctiform clinch depressions.
  • the latching element is generally rotatably mounted on the rotary latch, defining the position axis.
  • the procedure here is usually such that the locking element engages with a bearing tooth in an associated joint recess of the rotary latch.
  • a motor vehicle lock and in particular a motor vehicle door lock is made available which, first of all, provides particularly low-noise operation with increased comfort due to the latching element that is implemented.
  • Latching element ensures that the interaction takes place more or less "rolling", so that the background noise is reduced and reduced forces are required, and as a result there are improvements in comfort. According to the invention, all of this is paired with perfect radial and axial guidance of the latching element, so that the overall kinematics are improved once again. This is where the main advantages can be seen.
  • FIG. 1 shows the motor vehicle lock according to the invention, and in particular the motor vehicle door lock, schematically and partially in a side view
  • FIG. 2 shows a further view of the motor vehicle lock or motor vehicle door lock according to the invention.
  • a motor vehicle lock is shown, which is not limited to a motor vehicle door lock.
  • this has a locking mechanism 1, 2 made up of the two essential locking mechanism components, namely rotary latch 1 and pawls 2.
  • the locking mechanism 1, 2 can also be equipped with more than one pawl 2, although this is not shown in detail .
  • Another basic structure includes a latching element 4 arranged in the engagement area 3 between the two locking mechanism components 1, 2.
  • the latching element 4 is rotatably mounted on the rotary latch 1 and can pivot movements in a locking mechanism plane E spanned by the locking mechanism 1, 2.
  • the design is concrete and made in the exemplary embodiment in such a way that the locking element 4 is rotatably mounted on the rotary latch 1 and has a bearing tooth 4a for this purpose.
  • the bearing tooth 4a on the locking element 4 is located at one end of the Latching element 4, opposite to the other end of the locking element 4, which interacts with the pawl 2 according to the embodiment.
  • this opposite end of the locking element 4 is equipped with a reinforcement 4b.
  • the bearing tooth 4a as a whole engages in a joint recess 1a of the rotary latch 1 in the engagement area 3 .
  • a bearing axis 5 is defined, about which the latching element 4 is pivotably mounted in the locking plane E, specifically in relation to the rotary latch 1 supporting the latching element 4 .
  • the relevant locking component 1, 2 supporting the locking element 4, in the exemplary embodiment the rotary latch 1, is now equipped with a cover 6, which at least partially overlaps the locking element 4 and is made of the same material, for the purpose of axially securing the locking element 4 2 can understand.
  • the rotary latch 1 is equipped in several layers with a core layer 1b and a cover layer 1c having the covering 6 . It can be seen that, according to the exemplary embodiment, the core layer 1b is provided and implemented between two cover layers 1c on both sides. The cover layers 1c on both sides are each equipped with the cover 6, so that in this way the bearing axis 5, which runs between the two covers 6 as it were in the side view, is hereby secured axially. The same applies to the locking element 4.
  • the design is such that the covering layer 1c protrudes in each case over the area of the core layer 1b by the amount of the covering 6 .
  • the cover 6 is designed and designed in such a way that it at least covers the engagement area 3 between the relevant locking mechanism component 1, 2, in the exemplary embodiment the rotary latch 1, and the locking element 4, in order in this way to ensure the axial securing of the bearing axis 5 and thus of the locking element 4 to be able to provide.
  • the two cover layers 1c on both sides of the core layer 1b with the covers 6 provided by them ensure that the locking element 4 is secured axially as a result, and consequently cannot perform any axial movements along the bearing axis 5. Rather, this reduces any movements of the locking element 4 relative to the rotary latch 1 in the end and solely to the locking plane E, within which the locking element 4 can move relative to the rotary latch 1 in a pivotable manner.
  • the cover layer 1c or the respective cover layer 1c and the core layer 1b are generally made of the same metal or different metals.
  • a particularly tough steel can be used for the core layer 1b in order to be able to control the tearing forces on the locking mechanism 1, 2 that the core layer 1b usually has to absorb.
  • the cover layer 1c can be made of a steel that is not as tough as the core layer 1b.
  • a metal other than steel is also conceivable in this context for the realization of the covering layer 1c.
  • the covering layer 1c and the core layer 1b have the same or different material thicknesses si, S2.
  • the design is such that the core layer 1b has a multiple material thickness si compared to the material thickness of the cover layer. For example, thickness ratios of 2:1 and more are observed at this point.
  • the material thickness si of the core layer 1b is generally at least twice as large as the material thickness S2 of the respective cover layer 1c.
  • the layers 1b, 1c in question are clinched together at certain points, in that the layers 1b, 1c are joined or clinched together by stamps that act at certain points.
  • the layers 1b, 1c can also be firmly connected to one another via a heat-joining process. In such a heat joining process, the layers 1b, 1c are simply welded to one another. This can be done in detail by means of a spot welding process or also a laser welding process.
