In a drive train for a motor vehicle, which has a permanently driven primary drive train and a secondary drive train which can be connected to the primary drive train when necessary or decoupled therefrom, in order to couple or decouple from the primary drive train, there is provision for actuating a clutch apparatus of a device for power transmission and/or power distribution, in which the disengagement unit when providing the clutch actuation force which is required for the actuation of the clutch apparatus is operationally connected to secondary drive members or in which there is provided a drive clutch which, in order to provide the clutch actuation force required for the actuation of the clutch apparatus, is capable of producing an operational connection between the primary drive members or the secondary drive members and a manipulated variable unit of the disengagement unit.

Electromechanical lock utilizing magnetic field forces. An actuator is moved between a locked position and an unlocked position. In the locked position, a first permanent magnet directs a first magnetic field exerting a pushing force so that rotation of the first axle is blocked, and a second permanent magnet directs a second magnetic field exerting a pulling force so that the first axle is kept uncoupled with the second axle. In the unlocked position, the first permanent magnet directs a reversed first magnetic field exerting a pulling force so that the first axle is released to rotate, and the second permanent magnet directs a reversed second magnetic field exerting a pushing force so that the first axle becomes coupled with the second axle.

A rotatable magnetic coupler includes disc carrying, circumferentially spaced magnets arranged in rows on a first side of the disc. The magnets are oriented such that one pole of a first magnetic polarity from each magnet faces outwardly from the disc rotation axis while the other pole of a second magnetic polarity for each magnet faces inwardly toward the axis of rotation. The inner row magnets are preferably of lesser height than the outer row magnets to intensify a virtual gear-coupling effect in the magnetic field lines. A magnetic coupling is formed when two such couplers are rotatably mounted sufficiently close to one another that their magnetic fields are coupled together, such that rotation of one coupler rotatably drives the second coupler.

A rotational power transmission mechanism includes: an input shaft and an output shaft that are apart from each other; a first rotary member fixed to a tip end of the input shaft on an output shaft side of the input shaft; and a second rotary member fixed to a tip end of the output shaft on an input shaft side of the output shaft so as to face the first rotary member. Into recessed portions, projected portions are inserted, permanent magnets are respectively provided on a pair of contact surfaces of each recessed portion and on a pair of contact surfaces of each projected portion in such a manner that the recessed portion and the projected portion repel each other at the respective pairs of contact surfaces where the recessed portion and the projected portion come into contact with each other.

A blending appliance includes a housing with a jar receiving area defined between an upper housing and a support base. A blender jar includes a base portion and a receptacle portion, and is configured to be laterally received within the jar receiving area of the housing. A magnetic coupling system includes an upper magnetic coupler disposed in the base portion of the blender jar and a lower magnetic coupler disposed in the support base of the housing. The upper and lower magnetic couplers are magnetically coupled to one another for driving a blade assembly disposed in the receptacle portion of the blender jar. A brake mechanism is disposed on the upper magnetic coupler and is configured to stop rotation of the upper magnetic coupler when the blender jar is removed from the jar receiving area.

A magnetic coupling rotor includes permanent magnets arranged at equal angular spacings about its axis of rotation, wherein they respectively face radially inwardly and radially outwardly with their pole faces, of which a respective one bears against a backiron body of ferromagnetic material. The backiron body is a cylindrical ring with smooth peripheral surfaces. Provided for the permanent magnets is a holding device comprising a not or only weakly magnetizable injection-moldable material in the form of a rotary-symmetrical body having recesses for receiving the permanent magnets. The diameters of the holding means and the backiron body are such that they can be fitted together coaxially such that the backiron body at least partially covers the recesses in a radial direction. Thus, formed between it and the holding means is an even number of insertion compartments into which permanent magnets may be inserted.

A drive unit (8) for driving a tool. The drive unit (8) has at least one first drive module (18) comprising a motor (12) and a wheel (32) driven in a rotary manner around an axis (16) by the drive module (18). The drive module (18) comprises a magnetic ring (22) surrounding the wheel (32), with which the wheel (32) is connected in a magnetically force-transmitting manner and with which the motor (12) is connected in a mechanically force-transmitting manner.
