Abstract
A vehicle drive device with a reduction device includes an input driving unit that provides a driving force, a transmission part comprising a first rotor, a second rotor, and a stator stacked in a rotational axial direction of the input driving unit, and an output part connected to one of the first rotor or the second rotor. In particular, the input driving unit is connected to the other of the first rotor or the second rotor.
Claims15
A vehicle drive device, comprising:
- an input driving unit that provides a driving force;
- a transmission part comprising a first rotor, a second rotor, and a stator that are stacked in a rotational axial direction of the input driving unit;
- a shaft that transfers the driving force of the input driving unit to the transmission part:
- an output part that receives the driving force of the input driving part via the shaft and outputs rotation, wherein a speed of the rotation is adjusted via the transmission part;
- and
- a housing that accommodates the transmission part and the input driving unit,
- wherein the output part is coupled to one of the first rotor or the second rotor, and the input driving unit is coupled to the other of the first rotor or the second rotor,
- wherein the first rotor includes a pole piece module, and
- wherein the stator is disposed between an upper portion of the housing and the pole piece module of the first rotor.
