Shift force assistance of a speed-changing transmission

The shifting device (11) has a sensor (4) i.e. path sensor, for detecting a shifting request from a driver. A mechanical connection (2) is formed between a hand shift lever (1) and a gearbox (3), where the lever is actuated by the lever. A shift actuator (6) is designed in the form of an electromagn...

Zusammenfassung:	The shifting device (11) has a sensor (4) i.e. path sensor, for detecting a shifting request from a driver. A mechanical connection (2) is formed between a hand shift lever (1) and a gearbox (3), where the lever is actuated by the lever. A shift actuator (6) is designed in the form of an electromagnetic linear-actuator and overlays a shift force (F-s) of the driver with an additional shift force over an electromagnetic field in a contact-less manner. The actuator has two coils (7, 8) and a magnetically conductive core (9) arranged within the coils. An independent claim is also included for a method for controlling a shifting device.
