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, 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. In particular, 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.
Claims10
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 housing in which the first driving module and the second driving module are accommodated;
- a transmission part comprising a first rotor, a second rotor, and a third rotor provided inside the second driving module;
- and
- an output part connected to one of the first rotor, the second rotor, and the third rotor,
- wherein the first driving module is connected to another one of the first rotor, the second rotor, and the third rotor that is not connected to the output part,
- wherein the second driving module is connected to yet another one of the first rotor, the second rotor, and the third rotor that is connected to neither the output part nor the first driving module,
- wherein two or more first bearings are disposed between the housing and a shaft part that receives rotation of the first driving module and forms a rotational axis of the second driving module,
- wherein two or more second bearings are provided on both sides of the shaft part on which the third rotor is coupled, and
- wherein two or more third bearings are provided between the housing and the first rotor and between the first rotor and the second rotor.
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 transmission part comprising a first rotor, a second rotor, and a third rotor provided inside the second driving module;
- and
- an output part comprising a first protrusion that protrudes from the first rotor and a second protrusion that protrudes from the second rotor,
- wherein the third rotor is coupled to the first driving module to receive the driving force from the first driving module, and
- wherein each of the first protrusion and the second protrusion of the output part provides a rotational output, the transmission ratio of which is controlled by the second driving module.
