Beschreibung
Zusammenfassung:	The drive device (10) has a primary hydraulic motor (12a), secondary hydraulic motor (12b), output shaft (16) and a coupling device (18). A coupling device (18) connects secondary hydraulic motor with output shaft during connection switching state. The coupling device decouples secondary hydraulic motor from output shaft during disconnection switching state. The coupling device has a synchronization element (20) comprising conical friction surface (22) that is movable relative to friction surface (26) of coupled gear (24) during connection switching state. Independent claims are included for the following: (1) working machine; and (2) method for operating drive device.
