Embodiment Construction

[0023] figure 1 A top view of a motor vehicle lock 1 is shown, in which a rotary locking fork 2 movable about an axis 3 surrounds a locking bow leg 9 of a locking bow (or lock catch) 7 . That is to say, the locked state of the motor vehicle lock 1 is reflected here, wherein the rotary locking fork 2 is fixed by the pawl 5 which can pivot around the pawl axis 6, that is to say, the motor vehicle lock 1 is only locked when the pawl 5 has been pivoted away ( This is achieved by the motor vehicle door handle (not shown here) and can only be opened again. The locking bow leg 9 moves on the rotary locking fork 2 via the receptacle 4 as far as the depth bottom 27 and thus ensures the locked state of the motor vehicle door, also not shown here, wherein the locking parts 30 , 31 ie the locking pawl 5 and the rotary The locking fork 2 is part of the motor vehicle door, while the locking bow 7 with the locking bow legs 9 is fastened to the body of the motor vehicle. The locking parts 3...

Abstract

The invention relates to a method for producing a motor vehicle lock with locking parts, namely a pawl and a rotary yoke, in which method the pawl and the rotary yoke are punched out of rolled sheet material to give a vertical or an approximately vertical edge with corresponding locking surfaces on the rotary locking fork and locking pawl, the locking pawl and the rotary locking fork are then equipped with a casing with the locking surfaces free, wherein the After stamping, the locking part is bent in the region of the main lock and / or in the region of the further lock to obtain a contour without punching grooves, and the locking part is then inserted into the lock housing.

Description

technical field [0001] The invention relates to a method for the manufacture of a motor vehicle lock with locking parts, namely a locking pawl and a swivel yoke, in which method the swivel yoke and the locking pawl are punched out of rolled sheet material to give a vertical Or approximately vertical edge (or called side), said edge has the corresponding locking surface on the rotary locking fork and the locking pawl, and then gives the rotary locking fork and The locking claws are equipped with casings. The invention also relates to a motor vehicle lock with a rotary locking fork and a pawl which locks the rotary locking fork in the locked state, wherein the rotary locking fork and the locking pawl are on the free end of the locking part on the edge produced when the locking part is stamped There is a corresponding locking surface at the top and a cladding vacating the locking surface. Background technique [0002] It is known in principle that the creaking noises that occ...
