The invention relates to a thrust washer (28) for an electric machine (10, 12) intended to be arranged on a shaft (16) between a bearing (18) and a rotor (14), preferably a rotating electrical contact element (24) impacted by brushes (38), and/or a disk pack (36) of the rotor (14). The thrust washer (28) is provided with an area for sealing having two end faces (32, 34). On each end face (32, 34), at least one radial abutment section (50, 52) for the bearing (18), or the rotor (14), is provided. The thrust washer (28) according to the invention is characterized in that it is made of at least one hard component (54) and one soft component (56), wherein the part of the radial abutment section (50, 52) abutting the rotor (14) and/or the bearing (18) is formed by the soft component (56).

The invention relates to an arrangement for the damped bearing of a rotor shaft (1) of an electric machine. The invention also relates to an electric machine comprising a rotor shaft (1) and at least one such arrangement. The invention further relates to a method for the damped bearing of a rotor shaft (1) of such an electric machine. In order to provide an alternative for the damped bearing of a rotor shaft (1), it is proposed that the arrangement has a bearing unit (2), which can be arranged between the rotor shaft (1) and a housing (3) of the electric machine, and a damping element (4), which can be arranged between the bearing unit (2) and the rotor shaft (1) or between the bearing unit (2) and the housing (3), wherein the damping element (4) comprises a mesh of metal wire (5).

A bearing assembly for supporting a unit of a motor vehicle on a structural component of the motor vehicle includes four bearings with an elastic center. The four bearings are arranged on the structural component of the motor vehicle such that the elastic centers of the bearings together define a two-dimensional surface on which the center of mass of the unit to be supported is located.
