Abstract (en)
[origin: CN104821473A] The invention relates to a brush unit for electrically contacting a curved surface (3.1) of a slip ring (3). The brush unit includes a brush holder (1;1') and a resilient brush (2;2'). The resilient brush (2;2') is mounted to the brush holder (1;1') in such a way that the brush (2;2') is resiliently preloaded between two points (P1;P2) at which the brush (2;2') is supported against the brush holder (1;1') and exhibits a camber (2.1). The brush is in contact with the brush holder (1;1') between the two points (P1,P2). Furthermore, the invention relates to a collector ring device with the corresponding brush unit.
