Brush device, electric machine

1. A brush device, comprising at least one brush holder which has at least two brush boxes for receiving in each case one brush, wherein the brushes are mounted in a displaceable manner in the respective brush boxes and wherein a helical spring is pretensioned in each case between one of the brushes and a stop in the respective brush box, and comprising at least two elastically deformable electrical conductors, which are each connected with an end thereof to one of the brushes, wherein the respective stop is configured at least in regions annularly with a through opening and the respective electrical conductor is routed from the respective brush through the respective helical spring and the through opening of the stop supporting said respective helical spring to a connection at an end of the respective brush box, wherein the respective brush and the respective helical spring in each case extend along a common axis, and wherein a lateral deflection space for the electrical conductor is disposed in each case along the common axis, such that the helical spring is disposed between the lateral deflection space and the brush along the common axis, and wherein the entire respective lateral deflection space is disposed within the brush holder along the common axis between the respective connection and the respective stop, wherein a cross section of the deflection spaces is configured L-shaped in each case.
