A coupling device is provided with a gearshift sleeve for a gearshift transmission. The gearshift sleeve via a first inner toothing optionally couples a first or second coupling gear rim of a first or second toothed gear wheel to an outer toothing of a hub body. The gearshift sleeve comprises a second inner toothing, with which the gearshift sleeve can be brought into engagement with the second coupling gear rim of the second toothed gear wheel and simultaneously via the first inner toothing with the first coupling gear rim of the first toothed gear wheel subject to freewheeling of the hub body. |
