Abstract
A vehicle drive device with a variable transmission includes a first driving module that provides a driving force, a second driving module that controls a transmission ratio, and a reduction gear part comprising a first sun gear, a second sun gear, and a planetary gear provided inside the second driving module. An output part is connected to one of the first sun gear, the second sun gear, and the planetary gear, and the first driving module is connected to another one of the first sun gear, the second sun gear, and the planetary gear that is not connected to the output part.
Claims14
A vehicle drive device with a variable transmission, the vehicle drive device comprising:
- a first driving module that provides a driving force;
- a second driving module that controls a transmission ratio;
- a reduction gear part comprising a first sun gear, a second sun gear, and a planetary gear provided inside the second driving module;
- and
- an output part connected to one of the first sun gear, the second sun gear, and the planetary gear,
- wherein the first driving module is connected to another one of the first sun gear, the second sun gear, and the planetary gear that is not connected to the output part, and
- wherein the second driving module comprises a second rotor, and the planetary gear is disposed inside the second rotor of the second driving module, thereby allowing the transmission ratio to be controlled based on an electric current applied to the second driving module.
