Abstract

The invention concerns a morphology matrix for forming the cross-sectional shape of a short gearing tooth, in particular on toothed wheels of motor vehicle gearboxes. The short gearing teeth are formed on a cylindrical section of a gear wheel or gear shift sleeve, the axis of this section coinciding with the displacement axis of the gear shift sleeve. Each tooth comprises a tip which is chamfered in roof-like manner and has lateral flanks (3) which are shaped towards the tooth base (1) so that they have a relief at least over part of their height. The lateral flanks (3) terminate in a radiused tooth base (4), all of the teeth, or some thereof defined according to a regularly changing pattern, having at least a morphology defining the shape of the lateral flanks.
