Definitions

  • the invention relates to a current transmission arrangement for electric motors comprising at least two carbon brush holders with carbon brushes received by them, a carrier for the carbon brush holders and for electrical components, electrical connections and fastening means for securing the carrier in one Casing.
  • a corresponding power transmission arrangement comprises a Support plate, which is interspersed by the shaft of the electric motor. Diametrically to the longitudinal axis extend quiver-shaped carbon brush holders, in which carbon brushes axially displaceable are arranged to abut a commutator.
  • the support plate itself points a punched grid, via which an interconnection of both the carbon brush holders as also takes place of electrical components such as chokes or capacitors.
  • a basically same structure has a brush carrier plate according to DE 44 44 645 A1 on.
  • a brush carrier plate according to DE 44 44 645 A1 on.
  • the present invention is based on the problem of a current transmission arrangement of the type mentioned in such a way that in a compact design a desired interconnection of carbon brushes and electrical components takes place, wherein An arrangement should be possible even in confined spaces. It should in particular separate punched grid or connectors for fixing the arrangement not be required.
  • the invention essentially provides that the carrier a Board is out of the resilient tongue elements as the carbon brush holders, which extend along the longitudinal axis of the electric motor that the carbon brushes with the Carbon brush holders are integrally connected and that from the board contact fingers when both the fastener and the electrical connection go out.
  • a power transmission arrangement in which additional parts for fixing the arrangement and commutation of the electric motor are not required.
  • due to the cohesive as welded connection between the carbon brush and the carbon brush holder is an insert for high currents z. B. for DC-variable motors with rated currents between 30 and 35 amperes possible.
  • the board along the longitudinal axis of the electric motor, So the axis of the anchor extends. Also can easily one to the anchor longitudinal axis be given inclined arrangement, since it is necessary in this case alone is that the carbon brush holder forming resilient tongue elements bent so be that these extend along the armature longitudinal axis.
  • the board spans a plane parallel or runs approximately parallel to the longitudinal axis of the armature.
  • the resilient tongue elements that make up the carbon brush holders are in particular to leaf spring elements with which the carbon brushes back in particular are joined by welding materially.
  • the carbon brush leaf spring side a z. B. bronze made of sintered alloy area, the is welded to the leaf spring element.
  • the leaf spring element itself can be inserted or rammed into the board. additionally a soldering is done to ensure the required electrical connection.
  • the leaf spring elements can be received by a support structure, which ensures that the forces transmitted by the leaf springs to the carbon brushes, via which the carbon brushes apply a force in the direction of the commutator of the Electric motors experienced, are caught, so that no high forces on the solder joint train to the board.
  • the leaf spring a carbon brush receiving base portion remote from the carbon brush L-shaped end portion, whose parallel or approximately parallel to the base portion extending free leg consists of two mutually spaced sections, which are plugged into the board or einrammbar and are soldered.
  • Carbon brush side end of the base portion may have a U-shape in section, their side legs along outer surfaces of preferably a flat cuboid geometry run carbon brush.
  • Flat cuboid geometry means that the carbon brush has a small or smaller axial extent compared to the width.
  • the invention provides that the electrical components a radio interference suppression and / or an overload protection and / or a Hall IC with resistance and / or include a thermal monitor.
  • a special compact design gives sch then, if between two diametrically to the anchor longitudinal axis arranged leaf springs on the board a thermal monitor as well as two Suppression chokes are arranged. Further, facing away from the carbon brush holder Board surface a varistor, a capacitor and / or an X2Y capacitor element out. A corresponding X2Y capacitor element is then connected to a ground connection from the board.
  • FIGs. 1 and 2 is a detail of a housing 10 of a different views Electric motor as a DC motor shown in which a not shown anchor with Commutator can be used.
  • the motor housing 10 corresponding cylindrical Recordings 12, which are centrally enforceable by the armature shaft.
  • carbon brushes 14, 16 electricity supplied to the motor or its commutator.
  • the carbon brushes go 14, 16 of leaf springs 18, 20, which in a Board 22 are inserted or rammed and soldered.
  • the carbon brushes 14, 16 exist further preferably from a front interacting with the commutator made of carbon material section 24, 26 and a rear side made of bronze or sintered alloy section 28, 30, with an in section U-shaped portion 32, 34 of the carbon brush holder materially connected as is welded.
  • side legs 36, 38, 40, 42 of the U-shaped section extend 32, 34 along opposite side surfaces of the carbon brushes 14, 16.
  • the U-shaped sections 32, 34 extend from a tongue-shaped base section 44, 46 in turn merges into an L-shaped end portion 48, wherein parallel to the Base portion 46 extending leg 50 of two spaced apart sections 52, 54, which are inserted into the board 22 or einrammbar.
  • contact tongues 56, 58 which also in the board 22 are pierced or -gerammt and then electrically connected.
  • contact tongues 56, 58 a double function, since on this one hand, the mechanical Connection to the housing 10 and the other the electrically conductive connection to electrical connections.
  • the circuit board 22 has a varistor 70, an X2Y capacitor element 72 and a capacitor 74.
  • the X2Y capacitor element 72 can be connected to ground via a terminal lug 76 extending from the board 22.
  • a speed sensor e.g. as an additional board on the board 22 are plugged.
