A transfer case has a clutch unit, by means of which it is possible to produce the connection between a first output shaft (9) and a second output shaft (10), comprising: a) a first clutch part (20), which is mounted rotatably on the first output shaft (9), can be displaced in the axial direction and has first clutch disks (21), b) a rotatable second clutch part (25), which is connected in a rotationally fixed manner to the second output shaft (10) and has second clutch disks (26), c) a pressure plate (28) which can be displaced in the axial direction to the first clutch part (20), a first spring (31) being provided between this pressure plate and the first clutch part (20), and d) a claw clutch (40), comprising a primary part (41) and a secondary part (42), which is formed on the first clutch part (20), and a second spring (43). To ensure a rapid release at low base moment, connection during driving and without interrupting the traction force, the force exerted by the first spring (31) is greater than the force exerted by the second spring (43), and the claw clutch (40) is assigned a synchronizer clutch (50) which comprises a first synchronizer part (51), which is connected in a rotationally fixed manner to the first output shaft (9), and a second sychronizer part (52),which is connected in a rotationally fixed manner to the first clutch part (20). |
