Patent ID: 7461568

Claim:
A drive device with a transmission ( 4 ), the drive device comprising: a drive shaft ( 2 ) being directly connected with an engine; a shifting clutch ( 3 ) being located between the drive shaft ( 2 ) and an input shaft of the transmission ( 4 ), and the shifting clutch ( 3 ) detachably coupling the drive shaft ( 2 ) with a gear output ( 5 ) coupled to an output of the transmission; a shifting brake clutch ( 9 ) being located between the drive shaft ( 2 ) and the shifting clutch ( 3 ), and an output of the shifting brake clutch ( 9 ) being selectively combinable with the gear output ( 5 ); the output of the shifting brake clutch ( 9 )driving an auxiliary shaft ( 16 ) and an output from the auxiliary shaft ( 16 ) driving an output ( 18 , 19 ) which drives the gear output ( 5 ); a coaxial gear wheel ( 14 ), which is mounted on the drive shaft ( 2 ), forming the output of the shifting brake clutch ( 9 ) ; and at least two idle gears ( 19 , 20 ), mounted on the auxiliary shaft ( 16 ) and coupled with the output ( 18 , 19 ) of the auxiliary shaft ( 16 ), being optionally and alternately combinable with the gear output ( 5 ) via a coupling mechanism ( 21 ); wherein the coaxial gear wheel ( 14 ) meshes with an intermediate wheel ( 15 ) which engages with a fixed wheel ( 17 ) supported by the auxiliary shaft ( 16 ).
