A drive unit comprising at least one motor, at least one drive shaft and at least one connection shaft, wherein the connection shaft includes at least one receiving recess having a receiving opening at a first end side and is formed closed at a second end side. A first axial portion of the receiving recess has first dimensional tolerance characteristics with respect to the diameter, and the drive shaft is at least partially inserted into the receiving recess. A second axial portion of the receiving recess has second dimensional tolerance characteristics with respect to the diameter, and the first dimensional tolerance characteristics are different from the second dimensional tolerance characteristics, so that a clearance fit or transition fit is formed in the first portion between the drive shaft and the connection shaft and an interference fit is formed in the second portion between the drive shaft and the connection shaft.
A drive unit comprising at least one motor, at least one drive shaft and at least one connection shaft, wherein the connection shaft comprises at least one receiving recess, wherein the receiving recess comprises a receiving opening at a first end side and is closed at a second end side, wherein at least a first axial portion of the receiving recess has first dimensional tolerance characteristics with respect to the diameter, and wherein the drive shaft is at least partially inserted into the receiving recess,
A connection shaft having at least one receiving recess, the receiving recess having a receiving opening on a first end side and being closed on a second end side,
