Abstract
In a driving apparatus for a hybrid vehicle having an internal combustion engine and first and second electric rotating machines, it is configured to have a speed increasing mechanism that increases speed of an output of the engine inputted through an input shaft and transmits it to the first electric rotating machine; a speed reducing mechanism that reduces speed of an output of the second electric rotating machine and transmits it to an output shaft; a first clutch adapted to connect and disconnect a first driving force transmission path coupling the speed increasing mechanism and the output shaft; and a second clutch adapted to connect and disconnect a second driving force transmission path coupling the engine and the output shaft.
Claims4
An apparatus for driving a hybrid vehicle having an internal combustion engine and first and second electric rotating machines, comprising:
- a speed increasing mechanism comprising a first planetary gear mechanism and adapted to increase speed of an output of the engine inputted through an input shaft and transmit output to the first electric rotating machine;
- a speed reducing mechanism comprising a second planetary gear mechanism and adapted to reduce speed of an output of the second electric rotating machine and transmit output to an output shaft;
- a carrier of the speed increasing mechanism connected in a state incapable of relative rotation to the output of the engine;
- a sun gear of the speed increasing mechanism fixed at a housing;
- a ring gear of the speed increasing mechanism connected in a state incapable of relative rotation to an output of the first electric rotating machine;
- a carrier of the speed reducing mechanism connected the output shaft;
- a sun gear of the speed reducing mechanism connected in a state incapable of relative rotation to the output of the second electric rotating machine;
- a ring gear of the second speed reducing mechanism connected to the housing;
- a first clutch adapted to connect the ring gear of the speed increasing mechanism and the output shaft;
- and
- a second clutch adapted to connect the engine and the output shaft directly.
