Specific embodiment

Fig. 1 shows the gear clutch according to the prior art, which has axis 10, which is loaded with outer toothed portion 12, which cuts in axis.Wheel hub 14 has corresponding interior teeth portion 16.It can make axis 10 or wheel via actuator 18 Hub 14 is moved along axially towards another corresponding component (referring to the double-head arrow in Fig. 1) so that the intermeshing of teeth portion 12,16 and Torque can be transmitted.

It is readily visible from Fig. 1: in order to move teeth portion 12,16 fully or at least partially staggeredly, needing Biggish switching stroke and thus longer switching time.

Fig. 2 shows changeable gear clutch, in the gear clutch, teeth portion 12,16 shown in FIG. 1 it may be said that It is divided into spaced independent teeth portion.

Axis 100 has axis body 101.The axis body carries or has multiple ring gears 102, these ring gears are preferably designed for phase With part and it is respectively provided with outer toothed portion 104.Ring gear 102 is spaced apart from each other by spacer element 106, such as space washer or spacer ring It opens.Thus axial gap 108 is generated between adjacent outer toothed portion 104.

Ring gear 102 and/or spacer element 106 can be simple board, particularly plate stamping part.

Ring gear 102 is via fastener such as screw element, pin or the teeth portion as Fig. 3 later shows and illustrates It is rigidly attached with 101 torque of mandrel.

Wheel hub 110 includes hub body 112, which equally carries a large amount of ring gear 114, these ring gears again by Spacer element 116 is spaced from each other.

Axial gap 118 is generated between adjacent ring gear 114 and its interior teeth portion 120 by spacer element 116.

In gap 118, the teeth portion 104 of axis 100 is located at shown position not coupling, that is not switching In.Interior teeth portion 120 is either located in gap 108 or about positioned at the two of axial corresponding outside completely between outer toothed portion 104 A ring gear 102 is located at its side.
