text: referring to the drawings in particular , in a preferred embodiment of the present invention , the brush block generally designated 6 is used to transmit power currents to a slip ring 7 , which is mounted on the circumferential side of a cylindrical carrier 8 rotating about the axis 13 . the kinematic arrangement may also be reversed . the brush block 6 , which is present as one brush block or as a plurality of brush blocks , and the one or more slip rings 7 arranged in parallel form a current transmission unit 14 . fig5 schematically shows a current transmission unit 14 with terminals 15 for power current , which are connected to the brush blocks 6 . the slip ring or slip rings 7 has / have corresponding current connections . the brush block 6 comprises a plurality of multiwire sliding elements 3 ( hereinafter called mwse ), which are connected electrically in parallel and are arranged and fastened in a uniformly distributed pattern at an mwse carrier 4 in the direction of sliding 9 . a plurality of mwse 3 are arranged here at mutually spaced locations from one another one after another in an arc in the direction of sliding 9 or in the circumferential direction of the slip ring 7 . in this arrangement , the mwse 3 together form with their ends a shell - like enveloping curve curved concentrically with the axis of rotation 13 of the slip ring 7 and a sliding mat 10 , which is adapted to the contour of the slip ring . a plurality of contact points are thus obtained for current transmission . as is shown in fig1 , each multiwire sliding element 3 comprises an electrically conductive , rigid or flexible carrier blade 1 , which is mounted with one end at the mwse carrier 4 at a suitable fastening point 11 and at the other end of which a multiwire slip ring 2 is arranged . the multiwire slip ring 2 comprises a plurality of flexible , thin sliding wires , which are located next to one another and optionally one on top of another in a one - layer or multilayer , paintbrush - like arrangement . the sliding wires are preferably bent off outwardly or bent at their free end . the mwse carrier 4 has an inner wall 12 , which is bent concentrically with the axis 13 and at which a plurality of stepped incisions 5 are arranged in the embodiment according to fig2 . the stepped incisions 5 have a step side 5 ′, which points toward the middle 13 and is directed approximately tangentially to the slip ring 7 , and a step side 5 ″ that is directed at right angles thereto [ to the former step side ] and is preferably perpendicular . a plurality of mwse 3 are preferably arranged on each step side 5 ′ next to one another with fastening points 11 . the tangentially directed step sides 5 ′ are spaced from one another by the step sides 5 ″ directed at right angles to them . the stepped sections 5 follow the curvature of the slip ring and form a bent stepped contour with one another . the mwse 3 are directed essentially straight , and they lie with their carrier leaves , 1 flatly on the step side 5 ′ and are directed tangentially to the slip ring 7 . the mwse 3 of one step form an mwse layer a , b , the layers of a plurality of adjacent steps overlapping in a scale - like pattern . the layers a , b alternate regularly . the tangential step side 5 ′ is directed such that the free ends of the individual mwse layers a , b describe the enveloping curve 10 . the radius of this enveloping curve 10 is preferably somewhat smaller than the radius of the slip ring 7 that can be brought into contact . as a result , the elastic multiwire slip rings 2 of the mwse layers are preferably in contact with the circumference or the jacket of the slip ring 7 with a slight pressure . as is shown in fig4 , two or more mwse layers a , b are preferably offset in relation to one another and have different numbers of mwse 3 . for example , three mwse 3 are arranged next to one another in layer a . the layer b has two mwse 3 . the lateral offset of the layers a , b is such that the multiwire slip rings 2 of one layer a are exactly staggered in relation to the multiwire slip rings 2 of an adjacent layer b . the multiwire slip rings 2 of one layer a , b form a common two - or three - part sliding track on the circumference of a slip ring 7 that is to be brought into contact . the offset of the layers a , b is such that the different sliding tracks of the layers a , b together form a continuous , broad overall sliding track . the mwse 3 are connected to the mwse carrier preferably by welding or riveting in the area of the stepped incisions 5 at the points 11 . the carrier leaves 1 are fastened to the respective tangential step sides 5 ′. as is shown in fig5 , a plurality of brush heads 6 are preferably arranged distributed over the circumference of the slip ring 7 . furthermore , a plurality of brush heads 6 may be arranged next to one another in order to generate additional or broader sliding tracks . fig6 shows a variant of the mwse carrier 4 and of the shape as well as of the fastening of the individual multiwire sliding elements mwse 3 . the carrier 4 has an essentially smooth inner wall 12 that is concentric with the axis 13 in this embodiment without the stepped incisions present in the previous exemplary embodiment . at their carrier leaves 1 , the mwse 3 have foot parts or foot tabs 16 , which are bent on the end side , are in contact with the inner wall 12 in some areas , and are connected thereto in an electrically conductive manner in a suitable manner by welding , soldering , riveting , screwing or the like . various variants of the embodiment shown are possible . on the one hand , the number and the arrangement of the brush blocks 6 may vary . on the other hand , the number , distribution and arrangement of the mwse 3 within the brush blocks 6 may be modified . a disk - shaped design of the slip ring 1 with correspondingly bent brush blocks 6 and with mwse arranged one after another in an arc is also possible . while specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention , it will be understood that the invention may be embodied otherwise without departing from such principles .
