Current transmission sub-device of a current-excited synchronous machine as a drive motor in a hybrid on electric vehicle

A current transmission sub-device of a current-excited synchronous machine, a rotor of which has slip rings for a current supply and is contacted and supplied with electrical energy by carbon brushes, the current transmission sub-device comprising:

• at least one brush compartment for receiving a carbon brush, wherein the carbon brush has a pre-mounted stranded conductor and wherein the at least one brush compartment is applied on a brush carrier and has a stranded-conductor guide, in such a way that the carbon brush is insertable into the brush compartment and the pre-mounted stranded conductor is insertable through the stranded-conductor guide for connection to the brush carrier so as to reduce flapping;
• wherein the stranded-conductor guide is configured as a recess disposed at a front side of the at least one brush compartment and a bridge-like connection from an upper edge of the recess, which protrudes beyond the carbon brush to the brush carrier, at a distance from the carbon brush.
