Abstract

The invention relates to a drive assembly for transmitting torque, having a propeller shaft (1) and an intermediate bearing (2), such as they are used in motor vehicles for example, wherein the propeller shaft (1) includes a first shaft portion (3) with a first joint (8), a second shaft portion (4) with a second joint (21), and a third joint (5) in the form of a constant velocity fixed joint which connects the first shaft portion (3) and the second shaft portion (4), and wherein the intermediate bearing (2), which adjoins the constant velocity fixed joint (5) and is associated with the first shaft portion (3), including rolling contact bearing (15); in the drive assembly, the smallest inner diameters (dcA, dwz) of the outer joint part (25) of the joint (5) and of the second shaft tube (19) associated with the second shaft portion (4) are greater than the greatest outer diameters (Dw, DL) of the first shaft portion (3) and of the rolling contact bearing (15) of the intermediate bearing (2); this assembly permits the two shaft portions (3, 4) to move inside one another in a telescopic and substantially force-free way if the axially permitted maximum plunging path of the first joint (8) and the second joint (21) is exceeded, for example as the result of a frontal impact of the vehicle.
