ABSTRACT:
A multi-part propeller shaft for transmitting torque in the driveline of a motor vehicle. The shaft includes a first shaft portion (3) having a shaft tube (11) with an inner diameter (d), a second shaft portion (4) with an outer diameter (D) which is smaller than the inner diameter (d) of the shaft tube (11), and a universal joint (5) connecting the two shaft portions. The universal joint (5) has been provided in the form of a nominal separating region, and, after the universal joint (5) has been disassembled, due to an axial force resulting from a crash event, the first and the second shaft portion (3, 4) can be inserted into one another. To be able to accommodate kinetic energy, a deformable energy absorbing mechanism is provided in the shaft tube. The energy absorbing mechanism can be a filler member, a friction sliding element and/or a friction-inducing sliding assembly.
