Abstract:
An arrangement which operates an automated transmission for use in the power train of a motor vehicle has an element which can transmit motion to a gear selecting and shifting member of the transmission. The element is reciprocable by a first actuator which can employ an electric and/or fluid-operated and/or mechanical drive and is responsive to signals from an electronic control unit. A second signal-responsive actuator can be utilized to index the gear selecting and shifting member, either directly or by way of the motion transmitting element, in order to actually shift into or from a selected gear and/or to cause the member and/or the element to bypass an obstacle which can arrest the member and/or the element in an intermediate position in order to shift into or from one or more gears in certain types of transmissions.
Abstract:
A gearbox with an actuating device for automated shifting and selection of transmission ratios includes a gearbox operating element that is driven by an actuator. The actuator has a drive source with an output element. A swivel movement of the output element causes the gearbox operating element to shift into or out of a transmission ratio or to select one of the shift slots of a shift-gate pattern and to simultaneously apply a force to an energy-storing device. The energy-storing device acts on an intermediate element which acts on the gearbox operating element. At least one retaining element limits the actuation of the intermediate element to a predetermined position.
Abstract:
An apparatus for varying the phase of the camshaft in the combustion engine of a motor vehicle has an adjuster which is connected to the camshaft and is operable to adjust the phase of the camshaft prior and subsequent to starting of the engine. To this end, the adjuster is connected with a hydraulic drive system which can operate the adjuster while the engine is idle. Once the engine is started, the drive system receives pressurized fluid from the lubricating circuit of the engine. Prior to starting of the engine, the drive system receives pressurized fluid from a source other than the lubricating circuit or from a source which is provided in addition to the lubricating circuit. The other source is preferably the hydraulic circuit of the power steering system (such as a speed-sensitive power steering system) of the motor vehicle.
Abstract:
The phase of a camshaft in an internal combustion engine can be changed by the piston rod of a double-acting hydraulic cylinder and piston unit which is controlled by a valve having a spool movable axially by an electromagnet which is adapted to be influenced by a plurality of signals including those from the engine electronics.

Abstract:
The present invention relates to a segmented support plate (2) for a lamella, which support plate (2) is assembled from at least two segments (14, 16) in the manner of a jigsaw puzzle so as to form a boundary line (22) between the segments (14, 16), wherein the one segment (14) has a projection (28) which is inserted into a recess (32) in the other segment (16) so as to form a boundary line section (36) between the projection (28) and the recess (32), and the projection (28) and the recess (32) are shaped such that the adjacent segments (14, 16) engage behind one another, in relation to the circumferential direction (10, 12) of the support plate (2), in at least one first and one second partial section (64, 66) of the boundary line section (36). According to the invention, the projection (a) of the first partial section (64) onto a radial line (76) in the circumferential direction (12) at least partially intersects the projection (b) of the second partial section (66) onto the radial line (76) in the circumferential direction (12). The present invention also relates to a lamella, in particular a friction lamella for a multiplate clutch, having a segmented support plate (2) of said type.

Abstract:
A device for hydraulic control of gas exchange valves of a reciprocating internal combustion engine which has slave cylinders in operative connection with one or more gas exchange valves and master actuators in operative connection with at least one cam provided with a basic and cam profile of a camshaft that is rotatably driven by the engine and can be hydraulically connected to the slave cylinders. The device also has a control device controlled by an actuating member, the device controlling the volume of hydraulic liquid fed to the slave cylinders, and at least one feed line, via which low pressure liquid from a pressure source can be fed to the device by means of at least one non-return valve. The actuators have displaceable vanes, a component carrying the vanes, and cells limited by walls. The vanes are in operative connection with the basic and cam profile of the cam.

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.
