Definitions
- the axial stop of the shift sleeve which is formed in conventional shift sleeves by the end faces of the sleeve body, results in the shift sleeve according to the invention from the protrusion of the teeth in the area of the intersections of the roof slopes, unless a corresponding axially recessed stop is provided.
- the gearshift sleeve can be pressed with an allowance 11, as is indicated by dash-dotted lines in FIG. 11. If after the sintering of the pressed switching sleeve, the protrusions 6 are compressed to the nominal dimension drawn in full lines during calibration, then greater densities occur in the region of the protrusions, which bring about a large compensation of the different press densities. With the aid of this measure, a sufficiently uniform material density can therefore also be ensured in the area of the protrusions 6 of the teeth 3.
