The invention relates to an actuator, comprising a drive (2) that drives a drive shaft (1), a first actuating element (3) operatively connected to the drive shaft (1) for actuating a switching apparatus, a spring element (5), which can be supported at one end on a housing component (16) of the actuator and is supported on the other end on a second actuating element (17) designed to load the spring element (5). The actuator according to the invention is characterized in that a rotatably mounted rotational element/gearwheel (13) that can be driven by means of the drive shaft (1) is provided, which rotational element has, on one side, a first control gate (7), which is operatively connected to the first actuating element (3) for actuation of the switching apparatus, and on the other side, a second control gate (8) for loading the spring element (5).

A method and apparatus for self-commissioning a bearingless-motor drive, which includes a bearingless motor and a control unit of the bearingless motor are disclosed. The motor includes at least one winding and at least one permanent magnet. The method includes generating a magnetic model, the magnetic model including a plurality of constant parameters; supplying, while the movable part remains standstill, to the at least one winding at least two unequal currents; measuring, with a magnetic sensor, flux linkages caused by said at least two unequal currents, respectively; calculating, with the magnetic model, flux linkages by inputting to the magnetic model current values equal to the currents supplied to the at least one winding; and fitting, with a least-squares fitting algorithm, at least one constant parameter in the magnetic model such that the difference between the measured and calculated flux linkages will be minimized.

An apparatus and system for actuating a manual gearbox, particularly of a motorcycle having a drive engine, and for carrying out a gear change while the clutch is engaged between the drive engine and the manual gearbox. The apparatus has a selector shaft, which can be actuated rotationally, and a gear-selector drum, which can be actuated rotationally. The gear-changing apparatus has a gear-change lever provided for actuating the selector shaft, and is adapted for influencing the output torque of the drive engine. One or more magnetic sensor(s), such as Hall effect sensors, are provided for sensing rotational actuation of the selector shaft and, optionally, for sensing rotational actuation of the gear selector drum. The sensor(s) send a signal to a controller and mechanisms known for affecting a change in gear to a lower or higher gear.

The invention pertains to a force transmitting device (100) for a transmission (200), particularly of a motorcycle, with a shift assist system, featuring a shift input shaft (30) with a shift lever connection (20) for receiving a shifting motion of a shift lever (300) and a transmission connection (40) for transmitting the shifting motion to a gear shifting gate (110) of the transmission (100), wherein the shift input shaft (30) features an energy accumulator (32) for the intermediate storage of at least part of the shifting force such that the relative motion between the shift lever connection (20) and the transmission connection (40) can be realized by changing the shifting force stored in the energy accumulator (32), and wherein the shift input shaft (30) features a sensor device (60) for detecting the relative motion between the shift lever connection (20) and the transmission connection (40).
