  • the straight running grooves of the punching contour are acted upon by the oblique grooves of the puzzle component or the associated locking surfaces during the movement process of the pawl, that it can only come to a selective contact to a few overlaps, so that the previously occurring interlocking the trained on both locking parts straight Punching contours no longer can occur. With at least two overlaps per groove, a uniform movement of the pawl past the rotary latch, so that even a uniform motion sequence is secured.
  • a special groove formation on the respective puzzle component according to a development of the invention given the opportunity to let the puzzle component consist of a material that compensates for the effect of the punching contour on the other locking part or ineffective or has a hardened or coated surface.
  • the effect of the odd grooves having punching contour is compensated by the hardened or coated surface, except that only the respective detent surface is to be formed accordingly during hardening and coating, while after the other possible solution yes, the entire puzzle component consists of a corresponding reibfreudigen material.
  • the invention is characterized in particular by the fact that a motor vehicle lock is created with a relatively small additional production outlay, in which the pawl and rotary latch are designed in the latching area in the area where they are both adjacent to each other or so that the previous noise load is significantly minimized ,
  • a uniform movement of the pawl is secured to the catch along, because of the special design of the locking surface preferably one of the locking parts, the movement is facilitated, because this separately formed locking surface is associated with a puzzle component that easily and safely in a puzzle-like contour of the Locked parts can be used.

Abstract

Pour minimiser la friction de glissement apparaissant entre le cliquet (5) et le pêne pivotant (2) d'une serrure de véhicule à moteur (1), il est avantageux d'affecter les diverses surfaces d'encastrement (12, 13) des deux parties de cliquet (30, 31) à une ou deux parties de puzzle (50, 51) au cours du processus de fabrication, les parties de puzzle étant insérées dans la zone d'encastrement principale (49) du cliquet (5) ou du pêne pivotante (2), en position fixe dans des contours (53, 54) en forme de puzzle adaptés en conséquence. Les surfaces d'arête (55 et/ou 56) peuvent alors compenser avantageusement l'effet des contours d'estampage gênants présents sur l'autre partie de cliquet (30, 31) de telle manière que les deux parties de cliquet (30, 31) se trouvent en contact réduisant le frottement.
