Verfahren zum Gangwechsel eines Antriebsstranges der für jedes Antriebsrad einen Schaltmechanismus besitzt

摘要

The method involves disengaging gear that is currently engaged on a maneuvered wheel (RM) and stopping it in the neutral position. Speed of rotation of motor (M) is changed for synchronizing it according to the reduction of gear ratio to be engaged on the maneuvered wheel. Target ratio of gear is engaged on the maneuvered wheel in a successive phase, and another drive wheel is then shifted.
