Power train for motor vehicle, has electrical machine for driving wheels of motor vehicle by speed changing mechanism, and input clutches intercalated between electrical machine and speed changing mechanism

摘要

The power train has an electrical machine (1) i.e. motor, for driving wheels of a motor vehicle by a speed changing mechanism, where the mechanism comprises gears on two different ratios. Input clutches (E1, E2) are intercalated between the electrical machine and the speed changing mechanism. Concentric primary shafts (7, 8) of the speed changing mechanism are respectively connected to the clutches, and carry fixed pinions (9, 11). The clutches are activated by independent actuators.
