Abstract:
An angle of rotation of a camshaft relative to an angle of rotation of a crankshaft in internal combustion engines is adjusted for influencing the control times of a valve operation sequence. A wobble plate mechanism including a wobble drive realizes the adjustment. The wobble plate mechanism is arranged between camshaft and crankshaft, preferably between camshaft and a camshaft wheel.
Abstract:
A phase displacement device (1) having a drive (2) with a drive shaft (4) and a transmission (5) for displacing the phase between a camshaft (9) and a crankshaft (12) is provided. The phase displacement device (1) has a sensor device (14, 15, 16, 17, 18, 19) with which the rotational speed or the position of a component (2, 3, 4, 5, 6) of the phase displacement device (1) is measured. In this way, a higher resolution is achieved with respect to the position of the camshaft.
Abstract:
A device for adjusting the phase position between a camshaft and a crankshaft is provided. A quick and precise electronic adjustment for mechanical adjustment devices for adjusting the phase position between a camshaft and a crankshaft have previously not been known. The adjustment device is a component of an electronic circuit, either automatically adjusting the desired phase position directly or indirectly via another parameter, with the circuit including at least one loop between the control device and the adjustment path, by which a quick and precise adjustment can be achieved. Such arrangements are needed for a quick and precise adjustment of the phase position of a camshaft in reference to a crankshaft in internal combustion engines.

Segmented steel core plates for either double sided or single sided wet clutch friction plates or separator plates and a process for making the same are disclosed.
Abstract:
The present invention relates to a control device for adjusting the angle of rotation of a camshaft in relation to the angle of rotation of a crankshaft, by means of a wobble-plate mechanism situated between the camshaft and the crankshaft, in which mechanical means for limiting the adjustment of the angle of rotation are situated between the crankshaft and the camshaft.
Abstract:
A control device and method for adjusting the angular velocity ratio (ωN(t)/ωK(t)) between a camshaft and a crankshaft is provided. Various control devices and methods for rotating the camshaft relative to the crankshaft provide a drive which may advance and retard the camshaft in comparison to the crankshaft. Previous systems have the disadvantage that either two drives in different directions are necessary for each actuation direction or the drive must have right-handed rotation and left-handed rotation. In the control device and the method according to the invention, the advancing of the camshaft is achieved by a drive in the running direction of the camshaft and the retarding is achieved by a braking device. It has been shown to be especially advantageous if an electric motor in two quadrant mode is used as the drive, which may then also be used as the braking device. Such a control device and method are required for setting the control times in internal combustion engines.
Abstract:
An operating device for an automated gear box having a shift gate with a selector slot, three or more shift slots intersecting the selector slot, and an actuator for actuating a gear or shifting shaft in shifting motions. The shifting shaft has a pin or shaft extending through the shift gate. A blocking device with one or more blocking elements moveable generally along the selector slot allows movement of the pin to an adjacent shift slot and shifting within the shift slot by the actuator while blocking further movement of the pin along the selector slot upon engaging a blocking element.

Abstract:
An arrangement for adjusting the angle of rotation of a camshaft (5) relative to a crankshaft is provided. The arrangement requires many components, which partially also require different operational conditions. The new arrangement is structured in a modular fashion, so that the components of the arrangement are no longer arranged inside a common housing, but rather are separately constructed according to their function and/or operational conditions, for example, they are used jointly by other control or adjustment devices. It is particularly advantageous that such arrangements can be produced in a reduced size and in a more cost effective manner and can be used for adjusting the valve play of internal combustion engines.
Abstract:
A gear arrangement has two turntables nested or arranged concentrically in one another, and interconnected with one another via a swashplate. The gear arrangement preferably is used for adjusting the angle of rotation of the camshaft relative to the angle of rotation of the crankshaft of an internal combustion engine to affect the control times of the charge-cycle valves of the engine. The swashplate is connected with the first turntable formed as a camshaft gear via at least one pin, and the swashplate is connected with the camshaft via the second turntable by means of a gear ring.
