Abstract
A hybrid vehicle includes: an engine that can output power to a drive gear; a CVT that can steplessly change the speed of power inputted to a primary shaft and output the power to a secondary shaft; a planetary gear mechanism including a sun gear connected to the secondary shaft, a ring gear that can rotate in a direction opposite to a rotational direction of the drive gear in conjunction with the drive gear, and a carrier connected to a carrier shaft; a clutch that connects and disconnects the drive gear to and from the primary shaft; a motor that can input and output power to the primary shaft; and a battery that can supply and receive electric power to and from the motor.
Claims11
A power output apparatus that outputs power to a drive shaft, said power output apparatus comprising:
- a power generation source that can output power to a predetermined rotational element;
- a continuously variable transmission device that can steplessly change the speed of power inputted to an input shaft and output the power to an output shaft;
- a planetary gear mechanism including a first input element connected to said output shaft of said continuously variable transmission device, a second input element that can rotate in a direction opposite to a rotational direction of said rotational element in conjunction with said rotational element, and an output element connected to said drive shaft;
- a connection and disconnection device that connects and disconnects said rotational element to and from said input shaft of said continuously variable transmission device;
- an electric motor that can output at least power to said input shaft of said continuously variable transmission device;
- and
- an accumulator that can supply and receive electric power to and from said electric motor.
A vehicle including drive wheels connected to a drive shaft, said vehicle comprising:
- a power generation source that can output power to a predetermined rotational element;
- a continuously variable transmission device that can steplessly change the speed of power inputted to an input shaft and output the power to an output shaft;
- a planetary gear mechanism including a first input element connected to said output shaft of said continuously variable transmission device, a second input element that can rotate in a direction opposite to a rotational direction of said rotational element in conjunction with said rotational element, and an output element connected to said drive shaft;
- a connection and disconnection device that connects and disconnects said rotational element to and from said input shaft of said continuously variable transmission device;
- an electric motor that can output at least power to said input shaft of said continuously variable transmission device;
- and
- an accumulator that can supply and receive electric power to and from said electric motor.
