Commutator motor e.g. direct current motor, for motor vehicle, has commutator ring stuck with rotor shaft, supported at axial bearing part and used as component of axial bearing, and axial-radial sliding bearing designed as axial bearing

摘要

The motor has a commutator ring (30) on a rotor shaft (12) that is supported with an axial-radial sliding bearing (16) and a radial sliding bearing (18). The bearing (16) is designed as an axial bearing that is formed by the ring and an axial bearing part that is provided at a side of a housing (20), where the ring is axially supported at the part. The ring is stuck with the rotor shaft, where the ring is used as a component of the axial bearing. A thrust washer (44) is arranged between the ring and axial bearing part, and consists of lubricant-modified polyetheretherketones.
