ANTRIEBSEINHEIT MIT OPTIMIERTER KÜHLUNG

摘要

The invention relates to an electric drive unit having a steering motor and a driving motor which are arranged coaxially with respect to one another and which steer a vehicle wheel and drive in the sense of a driving movement, respectively. A first motor (1) has a hollow drive shaft (2), through which a second drive shaft (3) of the second motor (4) protrudes. Furthermore, the second drive shaft (3) protrudes through an outer wall (5) of the drive unit and is connected on the outer side (6) fixedly in terms of rotation to an impeller wheel (7), by which air for cooling is blown on the outside along the housing of the drive unit.
