摘要： A camshaft adjuster for adjusting the relative angular positions of a camshaft and a crankshaft of an internal combustion engine in accordance with a setting shaft is provided. In which the setting shaft is driven by a setting assembly and has a driving connection with an adjusting gear through a coupling. The drive moment is transmitted in the coupling by a radial extension (21) of a first coupling half (19), which contacts a second coupling half (25) without play in a circumferential direction and which is movable in a direction of a Y-Y axis relative to a second coupling half (25). This permits compensation of eccentricities between the setting shaft of the setting assembly and the adjusting gear.

摘要： A control structure for the adjusting motor of an electric camshaft adjuster in an internal combustion engine is provided. The control structure includes a controller which processes measuring signals of the internal combustion engine to control data for the adjusting motor. A controller which has meaningful values for the adjusted setpoint rotational speed of the adjusting motor, even when the input differential signal has a zero value, is obtained by applying the signal of an uncontrolled rotational speed to the output signal of a controlled setpoint rotational speed.

摘要： A device for varying valve timing in an internal combustion engine comprises an adjusting mechanism for varying an angle of rotation between a drive pinion (2) and a camshaft (end portion of the camshaft 1), said adjusting mechanism being configured as a wobble transmission. The drive pinion (2) comprises a first front-end gearing (9) and a disk (10) comprises a second front-end gearing (11), which first and second front-end gearings mesh partially with each other, and the number of teeth of said front-end gearings differ from each other by at least one tooth. To reduce the overall dimensions of the device and avoid gearing lash, it is proposed, on the one hand, to connect the disk (10) rotationally fast to the camshaft (1) and on the other hand, to configure the disk (10) in axial direction of the camshaft (1) as a flexible element that can be deformed in axial direction by an adjusting device (thrust plate 17).

摘要： A device for electrically adjusting the relative rotation of two shafts, particularly a camshaft (15) in relation to a crankshaft of an internal combustion engine is provided. The adjusting device includes an adjusting gear system which is embodied as a triple-shaft gear mechanism and is provided with a crankshaft-fixed input part, a camshaft-fixed output part, and an adjusting shaft (13) that is connected in a torsion-proof manner to an electric adjusting motor shaft (32) of an electric adjusting motor (3). The adjusting motor (3) is configured as a brushless DC motor having a housing-fixed stator (35) and a permanent magnet rotor (34). A high degree of adjustment accuracy and adjustment speed are provided with minimal space requirements and low power consumption. This is achieved through the use of a double eccentric gear mechanism (2) and a double planetary gear mechanism, which are provided with a speed reduction of up to about 1:250 and low friction, as an adjusting gear system while using a highly inductive permanent magnet rotor for the adjusting motor (3).
