DRIVE SYSTEM FOR MOTOR VEHICLES

摘要

The invention relates to drive systems for motor vehicles, comprising a first electric motor and a second electric motor. The drive systems are characterised in particular by great efficiency. For that purpose the rotor of the first electric motor is either directly connected to an output or can be detachably connected to an output by means of at least one first switch element. Firstly, the rotor of the second electric motor is connected directly or detachably via a switch device to at least one assembly. Secondly, the rotor of the second electric motor is or can be connected either to the central gear of a planetary gear system or to the central gear of a planetary gear system and also via a second switch element detachably to the rotor of the first electric motor. The output is connected to the external gear of the planetary gear system. Between the external gear and the central gear of the planetary gear system there is at least one planet gear. Furthermore, the planet carrier of the planetary gear system can be detachably connected to a fixed part via a control unit.
