摘要： A brush unit for an electric machine has a simple and low-cost but robust design, and can be assembled at low-cost using simple process steps comprises four ring-shaped board elements are stacked on each other, namely two outer circuit boards, each of which is electrically conductively connected to one or more brushes. Two guide boards made of electrically insulative material disposed therebetween, comprise a shape having protrusions and recesses for forming radial guides for the brushes and receptacles for springs acting on the brushes. The springs are spiral springs wound around a mandrel, the flat ends thereof protruding past the springs being rotationally fixedly guided in a guide groove of each receptacle and able to engage behind a stop. In order to assemble the brush unit, the circuit and guide boards are stacked on each other in the axial direction and riveted, then the brushes are inserted in the guides in the radial direction and the springs are placed in the receptacles.
摘要翻译：用于电机的电刷单元具有简单且低成本但坚固的设计，并且可以使用简单的工艺步骤以低成本组装，包括彼此堆叠的四个环形板元件，即两个外部电路板，每个其电导电连接到一个或多个电刷。由电绝缘材料制成的两个引导板设置在它们之间，包括具有突起和凹槽的形状，用于形成用于刷子的径向引导件和用于作用在刷子上的弹簧的容器。弹簧是缠绕在心轴上的螺旋弹簧，其突出的弹簧的平坦端被旋转地固定地引导到每个容器的引导槽中并且能够接合在止动件后面。为了组装刷子单元，电路和引导板在轴向方向上彼此堆叠并铆接，然后将电刷沿径向方向插入引导件中，弹簧被放置在插座中。
