Method for gear shift of a doulble clutch gearbox and doulble clutch transmission with synchronizing device

摘要

The method involves using two gear input shafts and one gear output shaft. Each input shaft is provided with a friction clutch. In the output condition, one of the two couplings transmits an engine torque and the other coupling is open whilst the other gear shaft is brought to synchronous speed. The one coupling is widely opened, regulated by a slip regulator, so that it works at a theoretical speed of its engine-side half at the slide limit. The other coupling is closed in a controlled manner, until the one coupling operated by the slip regulator at the slide limit no longer transmits torque. The one coupling is then fully opened, so that the other coupling alone transmits the engine power. The double coupling gear (10) has two gear input shafts (E1,E2) and a gear driven shaft (A). For each input shaft a friction coupling (K1,K2) is provided.
