Abstract
A range-extending hybrid transmission system includes a first rotary power source, a generator-motor, a differential, and driving wheels. The system includes a first shaft extending from the rotary power source and a first clutch disposed on the first shaft. A second clutch is spaced apart from the first clutch. A generator-motor is connected to the first shaft or to a second shaft that is mechanically connected to the first shaft and/or the second clutch. A third shaft connected to the differential is mechanically linked to the first shaft and/or the second clutch. This configuration enables the decoupling of the engine, generator-motor, and drive wheels, allowing all power sources to contribute concurrently or independently.

A range-extending hybrid transmission system comprising:
- a first rotary power source;
- a generator-motor;
- a differential;
- and
- driving wheels, wherein
- the first rotary power source is mechanically connected to a first shaft;
- a first clutch and a second clutch sequentially disposed along the first shaft and configured to selectively and independently couple or decouple the first rotary power source, the generator-motor, and a drivetrain;
- a second shaft mechanically connected to the generator motor and extending from the first shaft between the first clutch and the second clutch;
- a third shaft
- extending from the first shaft downstream of the second clutch and mechanically connected to the differential;
- and
- the differential being mechanically connected to the driving wheels.
A range extending hybrid transmission system comprising:
- an engine,
- a generator-motor;
- a differential;
- and
- driving wheels, wherein
- the engine is mechanically connected to a first shaft;
- a first clutch is disposed on the first shaft and configured to selectively couple of decouple the engine from the first shaft;
- the generator motor is coaxial with the first shaft;
- a second clutch is disposed on the first shaft downstream of the generator-motor and is configured to selectively couple the generator-motor to at least one of the first shaft and a second shaft;
- the second shaft extends from the second clutch and is mechanically connected to a third shaft;
- the third shaft is mechanically connected to the differential;
- and
- the differential is mechanically connected to the driving wheels.
