Abstract
A hybrid powertrain may include a planetary gear PG that includes three rotational elements with a carrier C coupled to an engine, a motor generator MG directly coupled to one of the remaining two rotational elements of the planetary gear PG, a first driving gear D1 installed to be rotated by receiving driving force from the rotational element coupled to the motor generator MG, a second driving gear D2 installed to be rotated by receiving driving force from the other one of the remaining two rotational elements of the planetary gear PG, an output shaft OUT having a first driven gear P1 and a second driven gear P2 meshed with the first driving gear D1 and the second driving gear D2, respectively, and a first brake BK1 installed to switch a state limiting a rotation of the rotational element coupled to the second driving gear D2.
Claims4
A hybrid powertrain, comprising:
- a planetary gear including three rotational elements, wherein a carrier among the three rotational elements is coupled to an engine;
- a motor generator directly coupled to one of the remaining two rotational elements of the planetary gear;
- a first driving gear installed to be rotated by receiving driving force from the rotational element coupled to the motor generator;
- a second driving gear installed to be rotated by receiving driving force from the other one of the remaining two rotational elements of the planetary gear;
- an output shaft having a first driven gear and a second driven gear meshed with the first driving gear and the second driving gear, respectively;
- and
- a first brake installed to switch a state limiting a rotation of the rotational element coupled to the second driving gear,
- wherein a first clutch installed to intermit the driving force is provided between the rotational element coupled to the motor generator and the first driving gear, and
- a second clutch installed to intermit the driving force is provided between the rotational element coupled to the second driving gear and the second driving gear.
