Double clutch transmission and method to control it

摘要

The transmission unit is divided into at least two individual systems, each comprising an input shaft to be coupled with a drive shaft by a friction clutch and for the creation of several transmission levels. A specific maximal speed of rotation of the input shaft is predetermined for each of the transmission levels. When particular transmission levels are parallel used in both systems a limitation of the revolution speed of the input shaft of the higher ratio of transmission is introduced.
