Definitions

  • the invention relates to a method for producing motor vehicle locks with the locking parts catch and pawl, in which the rotary latch and the pawl punched out of rolled sheets perpendicular or approximately vertical edges with corresponding locking surfaces of the catch and pawl predefined and then provided with clearance of the locking surfaces with a sheath become.
  • the invention also relates to a motor vehicle lock with a catch and a locking latch locking the latch in the closed state, wherein catch and pawl corresponding locking surfaces on the resulting edges of the locking parts edges at the free end of the locking parts and these locking surfaces have a free sheathing.
  • CONFIRMATION COPY unscrewed the closed position, wherein the touching locking surfaces of both locking parts rub one another intensively, so that the grooves and grooves formed during punching can lead to a further creaking noise. Even with obliquely running punching marks according to DE 10 2007 060 626 A1, the adverse noise can not be completely avoided.
  • the present invention is based on the object to provide a manufacturing method and a motor vehicle lock, in which the creaking between the catch and pawl is avoided.
  • the object is procedurally achieved in that the locking parts angled after punching in the region of the main catch and / or another rest stanzriefenfill a contour and then inserted into the lock housing box.
  • the locking parts ie both the pawl and the catch are punched out of rolled sheets, so that the surfaces of both locking parts are smooth.
  • the invention makes use of this by at least one of the free ends of the locking parts is angled or bent in the region of the main catch and / or other detent areas, so that then not a free end of a stamped part bears against another free end of a stamped part, but that by the Anwinkein one end of a locking part or both ends now the bent rolled surface of the or the locking parts are adjacent to each other, so that the grooves or grooves having punching contours with the movement of both locking parts with each other can no longer be effective.
  • a locking part is bent after punching in the region of the main catch and / or other latching and then mounted and brought in the assembled state with the free punched end of the other locking part and thus a straight punch contour in contact ,
  • the locking surface of the two locking parts which come into contact with the movement during the movement or when supporting the catch by the pawl, are greatly reduced in area, as if provided according to the invention at the angle of the free end of the stamped locking part the angled free end easily curved arcuately about its transverse axis becomes.
  • the shape of the bend or the arcuate bend can be chosen so that only a small contact surface or just a slightly larger contact surface between the two locking parts remains, depending on how this proves to be useful in one or the other motor vehicle lock.
  • Another way to reduce the size of the contact surface in the region of the locking surfaces is that, when the bend in the free end of the stamped locking part, the free end is slightly bent about its longitudinal axis or the free end is milled, so that the center creates a slightly rounded back.
  • the milling has the advantage that this results in grooves that are inclined in a certain proportion to the vertical Stamping contour of the other locking part are executed, so that a reduction of the sliding friction is achieved here safely.
  • the device for solving the problem that the locking parts have at their free, a punching contour having end angling, so that their rolled locking member surface is directed against the free end of the adjacent locking member with this in abutment.
  • a trained locking part or appropriately trained locking parts make it possible that the catch and the pawl does not come to rest with the punching contour having free ends together, but rather with the rolled locking part surface, the emergence of the due to the smoothness caused by the rolling excludes adverse stick-slip effect.
  • Pawl a punched contour exhibiting free end with a bend and the catch has a free, directed against the bend and there to plant to bring free end or that the free end of the catch is formed on the bend.
  • Such an embodiment is already useful because the manufacturing cost is reduced, because only one of the two free ends of the locking parts must be angled, while the other free end remains unchanged with its punching contour in action.
  • the remaining on the free end, for example, the rotary latch punching contour is noiseless harmless because the existing grooves of the punching contour easily roll on the smooth surface of the bend or to be able to move grinding. This is true even if only the rotary latch has, for example, an angling, while the free end of the pawl has the disadvantageous punch marks.
  • the pawl is reduced at the free end in the plate thickness and the protruding end piece is bent or angled. Assuming that the pawl is a 4 mm thick component, so would reduce the plate thickness, for example, to about 2 mm at the free end, then to bend the projecting tail orPartwinkein, this has the advantage that the pawl then can easily rest on the lock case housing floor.
  • the pawl should be associated with a supplementary plate having a height compensating the height of the angled portion. Even with this training so the angling would not affect the positioning of the pawl in the lock case housing, because is wororg for a smooth support of the pawl on the bottom of the lock box housing.
  • the invention is characterized in particular by the fact that with a small additional manufacturing effort, a motor vehicle can be created in which the pawl and the catch in the rest area so in the area where they are both on or against each other are formed so that the previous noise pollution significantly minimized or completely prevented.
  • a uniform movement is ensured along the rotary latch, because the existing design of the pawl or possibly the catch the existing grooves of the punching contour can not react with each other, because the corresponding punching contour of the two locking parts or both locking parts so bent in another position is brought.
  • the different grooves generated during punching can therefore not interlock and lead to harmful noises.

  • the pawl 5 and the catch 2 are parts of the vehicle door, while the lock bracket 7 are fixed to the 0 bracket 9 on the body of the vehicle.
  • the locking parts 30, 31 of the locking mechanism 8 are produced in a preferably multi-part stamping process from corresponding rolled sheets, wherein at the free of the shell 10 locking surfaces 12, 13 initially at both locking parts 30, 31, the surface characterized by a punching contour 14
  • edges 15, 16 of the rotary latch 2 and the pawl 5 are provided with a sheath 10.

  • the locking part surface 1 1 rests with its rolled smooth surface against the free end 59 of the rotary latch 2, so that the existing there straight grooves 17 can not adversely affect.
  • the free end 58 of the pawl 5 straight grooves 17 on the locking surface 13 can not be adversely affected, because they are removed by the angled portion 60 from the region of the contact surface 65.
  • the pawl 5 is here secured by a supplementary plate 64 having a thickness which corresponds approximately to the height of the angled portion 60.
  • FIG. 3 shows a special shape of the bend 60, which is here arc-shaped, so that a reduced contact surface 65 is created.
  • This part of the bend can have exactly the locking part surface 61 as the rest of the area or else it is treated separately or formed, for example by a coating.
  • Pawl 5 and supplementary plate 64 move together.
  • the angled portion 60 is formed so that an arcuate contact surface 65 is generated, which also brings a reduction of the locking surface 13 (contact surface 65) with it again.
  • Figure 5 shows a pawl 5, wherein the free end 58 has an end piece 62, in which the thickness of the pawl 5 is reduced, so that the bend 60 can be made correspondingly easy. Above all, eliminates the need for a supplementary sheet, because the bend 60 does not extend beyond the bottom 66 of the pawl 5. It is clear that here, too, by the angled portion 60, the smooth, because rolled, locking part surface 61 comes into contact with the latching surface 12 of the rotary latch 2, which has the straight punched grooves 17.
  • FIG. 6 shows a perspective view of the rotary catch 2, which is pivotable about the axis 3.

  • the locking surface 12 indicates the main catch 22, that is, the position in which the pawl 5 prevents the catch 2 in the closed position at a pivoting back. Then as already mentioned, the locking part surface 61 in the bend 60 on the locking surface 12 of the rotary latch 2 and both can push past each other with reduced friction, without causing the adverse noise, because the straight grooves 17 of the catch 2 on the Rolled Sperreteilober Structure 61 can not get caught or locked with anything.
