Abstract: A bistable relay includes a rotatable lever element and a guide element mounted rotatably about a shaft. The guide element has a guide groove in which a projection of the lever element is guided. The relay also has a spring which is connected to the shaft and one end of the lever element. When the guide element rotates, the projection can in each case be pulled suddenly into different positions by the spring loading of the lever element. As a result, an actuating element connected to another end of the lever element can be moved into a closed position or into an open position in order to make or break an electrical connection. A motor vehicle having such a bistable relay is also provided.

Abstract: A traction mechanism, in particular for driving the camshafts of an internal combustion engine, is provided. The mechanism includes a drive wheel, a driven wheel, a traction element and first and second tensioner slide rails. One slide rail can be subjected to a clamping force by a first clamping device that is supported both on the slide rail and externally. The first slide rail is connected to the second slide rail in a manner that transmits a defined force or displacement.

Abstract: A belt assembly, particularly for driving camshafts of an internal combustion engine, includes a driving gear, at least one driven gear, a belt, and a first and a second tensioner blade that are joined to one another for transmitting a defined force and motion. One tensioner blade can be subjected to the action of tension force by use of a first tensioning device supported on the tensioner blade on one side and externally on the other, and the tensioner blades can be subjected to the action of tension force by use of a second tensioning device both with regard to one another as well as with regard to a case of the internal combustion engine.
