Abstract:
1. A power output apparatus configured to output power to a driveshaft, the power output apparatus comprising: an internal combustion engine; a first motor capable power input and power output; a second motor capable power input and power output; a power distribution integration mechanism having a first element connecting with a rotating shaft of the first motor, a second element connecting with a rotating shaft of the second motor, and a third element connecting with an engine shaft of the internal combustion engine and configured to allow mutually differential rotations of the three elements; and a change speed transmission assembly including: a first change speed differential rotation mechanism having an input element connecting with the first element of the power distribution integration mechanism, an output element connecting with the driveshaft, and a fixable element and configured to allow mutually differential rotations of the three elements; a first fixation device configured to fix the fixable element of the first change speed differential rotation mechanism in a non-rotatable manner and to release the fixable element in a rotatable manner; a first coupling device configured to couple and decouple the output element with and from the fixable element of the first change speed differential rotation mechanism; a second change speed differential rotation mechanism having an input element connecting with the second element of the power distribution integration mechanism, an output element connecting with the driveshaft, and a fixable element and configured to allow mutually differential rotations of the three elements; a second fixation device configured to fix the fixable element of the second change speed differential rotation mechanism in a non-rotatable manner and to release the fixable element in a rotatable manner; and a second coupling device configured to couple and decouple the output element with and from the fixable element of the second change speed differential rotation mechanism.
