The electrical motor includes a stator and a rotor configured to be rotated about an axis wherein the rotor includes at least three rotor subsegments, wherein a first and second rotor subsegment can be turned relative to one another about the axis in response to a rotation speed range being above a predetermined threshold value of a rotation speed of the electrical machine.

Electric motor with turnable rotor segments for reducing the magnetic flux

A rotor for an electrical machine includes a rotor body and an axis of revolution which extends in an axial direction and about which the rotor body is rotatable. The rotor further includes an outer casing surface which delimits the rotor body, at least one pole arrangement, and a movement mechanism for the at least one pole arrangement. The movement mechanism is designed such that the at least one pole arrangement is movable about a rotation axis which is oriented substantially parallel to the axis of revolution of the rotor. The at least one pole arrangement is also movable about the rotation axis in addition to rotation about the axis of revolution of the rotor.

An internal rotor for an electric machine includes a rotational axis, an outer circumferential face which delimits the internal rotor, a pole arrangement comprising a centroid, and an actuating mechanism for moving the pole arrangement towards the rotational axis or away from the rotational axis to set a first spacing between the outer circumferential face and the centroid. In an example embodiment, the actuating mechanism has an actuator for moving the pole arrangement. The actuator has a hydraulically operable piston, a pneumatically operable piston, an electric motor actuator, or converts an axial force to a radial force. In an example embodiment, the actuating mechanism is operatively connected to the pole arrangement. The actuating mechanism is arranged between the rotational axis and the pole arrangement, or the actuating mechanism is arranged between the outer circumferential face and the pole arrangement.

Electric motor with switchover elements in the magnetic circuit

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.

An internal combustion engine comprises includes a turbo-compound and the known F&#xf6;ttinger-coupling is replaced by a torsion vibration damper. The F&#xf6;ttinger-coupling, which is used to transmit power, has high losses in power when it is necessary to have a differential rotational speed between the input side and the output side, that is, the appearance of a slip. The losses are not used in a torsion vibration damper which has at least the same quality as a F&#xf6;ttinger-coupling.

The present invention broadly comprises a cone connection assembly for a torque converter, including: a first surface operatively arranged for connection to a crankshaft and a second surface on a cover of the torque converter. The first and second surfaces are arranged to be engaged and the first surface is arranged to transfer torque to the second surface via the engagement of the first and second surfaces. In some aspects, the crankshaft comprises a longitudinal axis, the first surface is disposed about the longitudinal axis, the cover comprises an outside surface, and the outside surface comprises the second surface. In some aspects, the first and second surfaces are arranged to be frictionally engaged or the first and second surfaces have complementary surface features and the first and second surface features are arranged to interlockingly engage.

In a motor vehicle with a clutch that is operable in an automated mode, parts () of the clutch-actuator and/or the control device of the actuator system are integrated in a carrier element () that is installed in an intermediate area between the clutch bell housing () and the transmission housing ().

Motor vehicle

An electromagnetic friction clutch has at least two clutch parts that are mounted so as to be rotatable relative to each other and movable toward and away from each other and that touch each other with a contact force in the position of use. The clutch parts are located in a magnetic circuit, which is guided in the clutch parts in a soft magnetic material in sheet form. Positioned in the magnetic circuit is an electromagnet having a soft magnetic core and a coil. The magnetic circuit has air gaps between the soft magnetic core and at least one of the clutch parts. The flux density in the magnetic circuit, and thus the contact force, is modifiable via the current applied to the coil. The magnetic flux changes at least ten flux crossover points one after the other in the direction of flow between the clutch parts. The cross section of the magnetic flux in at least one air gap is at least five times greater than the smallest flux cross section in the soft magnetic material.

Support shoes are provided between the spring and an outer wall of the damper structure and are arranged to slide along the outer wall with the spring as it undergoes compression and relaxation. The support shoes include roller bodies to reduce sliding friction between the support shoes and the outer wall.
