Abstract
The power transmission device includes an input shaft that rotates about its axis together with a vehicle wheel. A driving gear is arranged coaxially with the input shaft so as to rotate about the axis of the input shaft together with the input shaft. A driven gear meshes with the driving gear, and configured to transmit a rotational force to an output shaft connected to a regenerative energy converter. A wheel bearing for the vehicle wheel supports the input shaft such that the input shaft is rotatable about its axis relative to the driven gear.
Claims20
A power transmission device for a vehicle, the power transmission device comprising:
- a drive shaft for transmitting a driving force from a driving source to a wheel of the vehicle, the drive shaft having a first end to be coupled to the driving source and a second end opposite the first end;
- an input shaft connected to the second end of the drive shaft to receive the driving force from the drive shaft in the form of a rotational force, the input shaft being configured to rotate about an axis of the input shaft together with the wheel of the vehicle;
- a driving gear arranged coaxially with the input shaft, the driving gear being configured to rotate about the axis of the input shaft together with the input shaft;
- a regenerative energy converter configured to convert rotational force to regenerative energy;
- a driven gear meshing with the driving gear so as to be rotated by the driving gear, the driven gear being configured to transmit a portion of the rotational force to an output shaft connected to the regenerative energy converter, the driving gear being configured to draw off the portion of the rotational force from the input shaft;
- and
- a wheel bearing supporting the input shaft such that the input shaft is rotatable about the axis of the input shaft relative to the driven gear.
