Abstract
An electric drive for a vehicle and a vehicle is having at least one electric machine having a rotor shaft and a planetary transmission for dividing the torque introduced via the rotor shaft to a first output shaft and a second output shaft, wherein for decoupling the rotor shaft at least one switching element is provided relative to the torque transmission between the rotor shaft and an element of the planetary transmission.
Claims18
An electric drive for a vehicle, comprising:
- at least one electric machine having a rotor shaft;
- a first output shaft;
- a second output shaft;
- a planetary transmission configured to divide a torque introduced via the rotor shaft to the first output shaft and the second output shaft comprising:
- a first planetary gear set;
- and
- a second planetary gear set coupled to the first planetary gear set,
- wherein:
- a first element of the first planetary gear set is connectable or connected to the rotor shaft,
- a second element of the first planetary gear set is connected to the first output shaft,
- a third element of the first planetary gear set is connected to a first element of the second planetary gear set,
- a second element of the second planetary gear set is connected to a housing, and
- a third element of the second planetary gear set is connected to the second output shaft;
- and
- at least one switching element configured to decouple the rotor shaft is provided relative to torque transmission between the rotor shaft and the first element of the first planetary gear set of the planetary transmission.
