Abstract:
A protective circuit arranged on a printed circuit board has two conductor loops. At least one supply voltage track, at least one semiconductor switch with at least one terminal and at least one control component with at least one terminal are arranged on the printed circuit board. A first terminal of the control component and a first terminal of the semiconductor switch are connected electrically. A first conductor loop of the protective circuit is arranged on the printed circuit board so that it surrounds an electrically conducting connection between the supply voltage track and the semiconductor switch and/or the control component, and a second conductor loop is arranged on the printed circuit board so that it surrounds the electrically conducting connection between the first terminal of the control component and the first terminal of the semiconductor switch, and thereby screens the same from the semiconductor switch and at least from those regions of the control component that are also connected to the supply voltage track.
Abstract:
A ball joint, in particular for the wheel suspension systems of motor vehicles, an external, essentially cylindrical housing, an internal joint piece with a pin supporting a ball section and a bearing race surrounding the ball section, is retained in the cylindrical housing and has annular seals on both sides of the pin ends. In order to achieve a hydraulic damping function, annular gaps are provided about the pin adjacent to the ball section, filled directly or indirectly with a damping fluid.
