Problems solved by technology
The series structure will be gradually eliminated due to the low transmission efficiency; although the parallel structure has high transmission efficiency, it has the technical problem that it cannot adjust the working speed of the engine; although the hybrid structure overcomes the shortcomings of parallel connection, its comprehensive performance is also good. But the structure is complicated
[0003] At present, most of the typical parallel structures are arranged axially, that is, the engine, motor, and gearbox are arranged on one axis, the length is relatively large, the structure changes greatly, and the arrangement is difficult; The direction must be small, which will easily lead to a decrease in the working efficiency of the motor

The invention discloses an electrically-controlled mechanical transmission-based hybrid power device, which comprises an engine, a first clutch, a first gear, an electrically-controlled mechanical transmission, a second gear, a second clutch and a generator / motor. A pair of normally engaged first gear and second gear serves as a power coupling and distributing device; the electrically-controlled mechanical transmission is adopted as a transmission system; and the whole power device is small in structural change and low in modification cost based on the electrically-controlled mechanical transmission. The generator / motor is a slender type motor and is arranged on one side of the engine and fixed on the side surface of the engine; the problems that a parallel hybrid power vehicle is oversized in axial arrangement dimension and the motor is lower in efficiency in the prior art are solved; and purely electric, parallel driving and pure engine driving modes of the vehicle are realized due to the transmission mode for changing the power through the clutches. The driving modes are flexibly selected according to the vehicle running condition so as to improve the dynamic property, economical efficiency and emission property of the vehicle.
Description
technical field [0001] The invention relates to a hybrid power device based on an electronically controlled mechanical transmission, in particular to a hybrid power device based on an electronically controlled mechanical transmission. Background technique [0002] Generally, hybrid drive devices are divided into three structural types: series, parallel and hybrid. The series structure will be gradually eliminated due to the low transmission efficiency; although the parallel structure has high transmission efficiency, it has the technical problem that it cannot adjust the working speed of the engine; although the hybrid structure overcomes the shortcomings of parallel connection, its comprehensive performance is also good. But the structure is complicated. [0003] At present, most of the typical parallel structures are arranged axially, that is, the engine, motor, and gearbox are arranged on one axis, the length is relatively large, the structure changes greatly, and the ar...
