Abstract
A drive unit includes: an electric unit including a first electric motor for driving, a deceleration mechanism configured to transmit a rotation torque of the first electric motor to a drive wheel, a second electric motor configured to be driven by an internal combustion engine to generate electric power, and an acceleration mechanism configured to transmit a rotation torque of the internal combustion engine to the second electric motor. The first electric motor, the deceleration mechanism, the second electric motor, and the acceleration mechanism are housed in one housing.
Claims5
A drive unit comprising:
- an electric unit comprising a first electric motor for driving, a deceleration mechanism configured to transmit a rotation torque of the first electric motor to a drive wheel, a second electric motor configured to be driven by an internal combustion engine to generate electric power, and an acceleration mechanism configured to transmit a rotation torque of the internal combustion engine to the second electric motor, wherein:
- the first electric motor, the deceleration mechanism, the second electric motor, and the acceleration mechanism are housed in one housing, and
- in the housing:
- the first electric motor and the second electric motor are arranged in a front-rear direction of a vehicle with their respective rotation shafts parallel,
- the deceleration mechanism and the acceleration mechanism are arranged in the front-rear direction of the vehicle,
- the electric unit and the internal combustion engine are connected in a state of being arranged in a left-right direction of the vehicle,
- a first rotation shaft which is the rotation shaft of the first electric motor and a second rotation shaft which is the rotation shaft of the second electric motor are located on a front side and a rear side in the front-rear direction of the vehicle with a crankshaft rotation axis which is a rotation axis of a crankshaft of the internal combustion engine interposed therebetween, and
- when viewed in the left-right direction of the vehicle, the crankshaft rotation axis is located at a midpoint of a motor connecting line which is a line connecting the first rotation shaft and the second rotation shaft.
