ELECTRIC DRIVE UNIT |
摘要 |
An electric drive unit having an electric drive motor and a transmission. The electric drive motor has an armature shaft which extends, for example, to a worm shaft of the transmission. The shaft is embodied of one piece with the armature shaft. A first bearing and a second bearing are provided to support the armature shaft. The second bearing is embodied as a ball bearing with an outer ring, an inner ring, and balls. The inner ring is press-fitted in a rotationally fixed manner onto the armature shaft. The outer ring is slid into a receiving bore disposed in the transmission housing and is pressed against an axial stop face adjoining the receiving bore by means of a retaining part that is supported in an installation channel and has flexible tongues that are directed toward the outer ring. This axial pressing can be produced in an easy-to-assemble fashion and is also inexpensive thanks to a low cost of the retaining part. The proposed electrical drive unit can be used, for example, for at least one windshield wiper of a vehicle. |
