Automated vehicle manual gear mechanism has ultrasonic motor gearbox/clutch actuating drive with oscillation part with piezoelectric, elastic parts, moving part in frictional contact with elastic part

摘要

The arrangement has an automated gearshift gearbox shifted using several controllable shift elements and at least one automated engine coupling. The dry clutch coupling can be engaged/disengaged by a controllable actuator. At least one of the actuating drives (for gearbox and/or clutch) is an ultrasonic motor with an oscillation part containing piezoelectric and elastic parts and a movement part in frictional contact with the elastic part. The gear mechanism has an automated gearshift gearbox and at least one automated engine coupling. The gearbox can be shifted using several controllable gear shift elements and the dry clutch coupling can be engaged and disengaged by a controllable clutch actuator. At least one of the actuating drives (for gearbox and/or clutch) is an ultrasonic motor with an oscillation part containing a piezoelectric part and an elastic part and a movement part in frictional contact with the elastic part. AN Independent claim is also included for the following: (a) an automated motor vehicle engine coupling.
