was connected to the hub jacket 160 of the hub area 140 of the carrier plate 110 by way of caulking the inner diameter of the cylindrical shell shaped geared sheath 1200 is approximately equivalent to the radial diameter of the hub area 140 when the geared sheath 1200 is pressured in the axial direction upon the hub area 140 of the carrier plate 110 the inner gearing 1220 of the geared sheath 1200 cuts a counter gearing into the hub jacket 160 of the hub area 140 matching the inner gearing 1220 here chips developing from the material of the hub jacket 160 are accepted in the chip chamber 1230 the inner gearing 1220 and the counter gearing formed in the hub jacket 160 by the inner gearing lead to a tight fit of the geared sheath 1200 on the hub jacket 160 in particular the gearing generates a protection of the geared sheath 1200 from any distortion in the circumferential direction of the hub jacket 160 in the axial direction the geared sheath 1200 can be secured by one or more additional welding points between the geared sheath 1200 and the carrier plate 110 the fastening of the geared sheath 1200 described in fig3 and 4 on the carrier plate 110 by way of caulking shows the advantage in reference to the fastening described in fig1 and 2 of the geared sheath 200 at the carrier plate 110 by welding connections 220 230 that due to the lesser introduction of heat any considerable change.
