    摘要: A camshaft adjuster (1) having a variable ratio gear unit (2). Usually, a drive movement of an electrical actuating assembly (7) is transmitted into a variable ratio gear unit (2) of a camshaft adjuster (1) on the side which faces away from the camshaft (6). According to the invention, the abovementioned drive movement is transmitted in from the side of the variable ratio gear unit (2) which faces the camshaft (6). As a result, a further assembly, for example a vacuum pump, can be driven by the variable ratio gear unit (2) on the side of the variable ratio gear unit (2) which has become free and faces away from the camshaft (6). An actuating shaft (4) of the actuating assembly (7) is preferably mounted via a bearing (34) which is supported on a circumferential face of the camshaft (6). This results in a reduced axial overall size of the camshaft adjuster and extended possibilities for the arrangement of an actuating assembly and the connection of additional assemblies.

    摘要: An electromotive camshaft adjuster for adjusting the angle of rotation of the camshaft (14) of an internal combustion engine relative to the crankshaft thereof is provided. The camshaft adjuster includes a triple-shaft gear mechanism, which has a driving wheel (2, 2a′) that is fixed to the crankshaft and is embodied as a sprocket or a synchronous belt wheel, an output part which is fixed to the camshaft, and an adjustment shaft (18, 18′) which is connected in a rotationally fixed manner to a rotor of an electric adjustment motor, having a stator that is fixed on the internal combustion engine. In order to keep the effort for producing the adjusting gears relatively low, the triple-shaft gear mechanism is preferably constructed as a swashplate or single eccentric internal gear drive (1, 25), the effort for production thereof being minimized by forming the same in a non-cutting manner, reducing the number of components, and inexpensively adjusting or compensating the backlash.

    摘要: Traditional camshaft adjusters are connected to a lubricant circuit of an internal combustion engine. Lubricant flows which are too large flood the drive of the camshaft adjuster, which leads to needless churning losses in the drive and needless losses of the pump capacity of the lubricant for other structural components of the internal combustion engine. According to the invention, a flow element (59), which includes a throttle element or screen in the flow channel (26), is used. According to another embodiment of the invention, the throttle element or screen can be used in various ways.
