[0026] In this application, terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual quantity, priority or sequence relationship between these entities or operations.

[0033] In the present application, each clutch device may be a clutch or a synchronizer with an engagement / disengagement function.

[0034] The terms in this application are explained as follows:

[0035] TM motor: TM motor is a type of electric motor commonly used in automobiles, mainly used in the drive system of electric vehicles or hybrid vehicles.

[0036] GM motors are general-purpose motors that can be used in vehicles as power sources or auxiliary systems, such as air conditioning, water pumps, and oil pumps. They can also be used in the drive systems of certain vehicle models. They are widely used in various types of vehicles, providing the necessary power and auxiliary functions.

[0037] TM motors and GM motors are widely used in automobiles, and both motors are important components of modern automotive electrification.

[0038] E-CVT is an electronic continuously variable transmission specifically used in hybrid vehicles. It is called electronic continuously variable transmission technology or electronically controlled continuously variable transmission. E-CVT is actually part of the hybrid system, not a traditional transmission. It achieves power output by coupling the energy of the engine and electric motor.

[0039] ICE stands for Internal Combustion Engine, which is an internal combustion engine that uses fuel combustion to generate high-temperature and high-pressure gas pressure to push the piston to generate work.

[0040] EV, the full name of which is Electric Vehicle, is a car that uses pure electric drive technology.

This compact structure can reduce the overall volume, reduce losses during power transmission, and reduce the space occupied by the entire structure in the vehicle layout.
