A dual clutch gearbox for a motor vehicle comprising a first gearbox input shaft ( 20 ) with which at least one first gear is associated, and a second gearbox input shaft ( 22 ) with which at least one second gear is associated. An outer gearbox input shaft ( 22 ) embodied as a hollow shaft surrounds an inner gearbox input shaft ( 20 ), and a synchronization device is provided inside the gearbox. The synchronization device comprises at least one planetary gear set ( 30, 40 ) and an associated braking device ( 50 ), the planetary gear set being arranged with its sun gear, planet carrier and internal ring gear, essentially coaxially in relation to the gearbox input shafts ( 20, 22 ), and a first component ( 34; 42 ) selected from the sun gear, the planet carrier and the internal ring gear is coupled or can be coupled to the first gearbox input shaft ( 20 ) for the purpose of rotational engagement; a second component ( 32; 44 ) is coupled or can be coupled to the second gear box input shift ( 22 ) for the purpose of rotational engagement, and a third component ( 36; 46 ) can be braked by the brake device ( 50 ) of the synchronization device, which is supported or can be supported, directly or indirectly, on a gearbox housing.
