Abstract: A camshaft adjusting device having improved lubricant management including adjusting gearing for adjusting the angular position of a camshaft is proposed, the adjusting gearing having an input shaft, which can be coupled to a crankshaft, an output shaft, which can be coupled to the camshaft and an adjusting shaft, which can be coupled to an actuator. The adjusting gearing defines a rotational axis and the gearing forms a gearing interior, in which the input shaft, the output shaft and the adjusting shaft are operatively interconnected. The camshaft adjusting device has a lubricant supply for supplying the gearing interior with a lubricant and the lubricant supply is designed to form a lubricant sump in the gearing interior, the sump being radially outwards situated relative to the rotational axis.

Abstract: A control system for a vehicle includes a motor driver module, a correlation triggering module, a target phase angle module, and a correlation control module. The motor driver module controls an electric camshaft phaser of an engine based on a desired phase angle between a position of a crankshaft and a position of a camshaft. The correlation triggering module selectively generates a signal based on the position of the camshaft. The target phase angle module adjusts the desired phase angle to a predetermined phase angle in response to the generation of the signal. The correlation control module, in response to the generation of the signal: determines the position of the crankshaft when the camshaft is in a predetermined position; and selectively outputs a fault indicator based on a comparison of the position of the crankshaft and a predetermined crankshaft position range corresponding to the predetermined position.

Abstract: A planetary carrier supports a geared rotor from an inside in a radial direction, and receives a radial load in a first region, which is offset to one end from a center position in an axial direction. A ball bearing roller supports the planetary carrier from an outside in the radial direction in a second region, which is offset to an other end from the center position. The ball bearing roller is a single-row ball bearing roller that has an outer ring supported by a drive rotor, an inner ring which supports the planetary carrier, and a plurality of rolling elements which are rotatably installed in a single row to be in contact with and between the outer and the inner rings. The geared rotor is tilted relative to the axial direction, and contacts a driven rotor in the axial direction. An angle of the geared rotor relative to the axial direction is set to be smaller than a maximum allowable angle at which the inner ring is allowed to be tilted relative to the axial direction.

Abstract: 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).

Abstract: 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).
