Antriebssystem, insbesondere für ein Kraftfahrzeug

摘要

A vehicle V comprises a drive source E that drives the wheels L via a transmission system T. The transmission system has an epicyclic gearing P with three rotational members of which a first rotational member a is connected to the drive source E, a second rotational member c is connected to the wheels L, and a third rotational member s is connected to a brake B. The transmission system T furthermore comprises a transmission A which is parallel to the epicyclic gearing P, and an electric motor EM connected to the transmission. This transmission system T enables shifting between the various transmission ratios without torque interruption, using only one brake. The electric motor can take over propelling the wheels from the drive source. This is useful when the drive source is temporarily disconnected, or to facilitate synchronization of the transmission. Using an electric motor in this configuration, it is furthermore possible to drive off forward and backwards. This enables omitting a launch clutch.
