Embodiment 1

[0031] Such as figure 1 A DMT dual motor mixing transmission, including an engine, a flywheel 3, a clutch 4, a power battery, a generator 2, and a drive motor 7, and the output shaft of the engine is connected to the flywheel 3, the flywheel 3 is The clutch 4 is connected to the rigid connection to drive the rigid connection through the input shaft 8. The generator 2 of the transmission is directly connected to the input shaft 8, and directly connects the rotor 2 of the generator 2 to the rotor 2 of the generator 2, and the motor rotor shaft and the input shaft 8 are also omitted. The connection structure of the original generator 2 rotor shaft and the input shaft 8 is designed to reduce the axial arrangement of the transmission, thereby reducing the difficulty of the installation process of the part of the transmission. The generator 2 is electrically powered by the input shaft 8 by the input shaft 8 by the input shaft 8 to perform charging power generation. The engine rotates th...

Embodiment 2

[0042] The structure and principles of the present embodiment are substantially the same, and the difference is: figure 2 The mount 3 is fixed to the flywheel 3 in the present embodiment, and the input shaft 8 is rigidly coupled between the planetary discharge render 5 and the clutch 4. The input shaft 8 is also a rotor passed through the generator 2, such that the engine passed the speed of the randor discharge speed, which can be more compatible with the optimum generating speed speed of the generator 2, so that the power generation efficiency is improved, reducing the reduction Decelerator energy consumption.

Abstract

The invention provides a DMT dual-motor hybrid transmission, and belongs to the technical field of hybrid power. With the DMT dual-motor hybrid transmission adopted, the problem that an existing hybrid power system is high in energy consumption is solved. The transmission comprises a differential mechanism assembly, a generator, a driving motor, an input shaft and a flywheel which is connected with an engine crankshaft, the input shaft is in transmission connection with the differential mechanism assembly through a clutch, the input shaft is in transmission connection with the flywheel, the driving motor is in transmission connection with the differential mechanism assembly, the generator is located between the flywheel and the clutch. the input shaft penetrates into the generator and is connected with a rotor of the generator, and the input shaft and the flywheel are coaxially arranged. The transmission is simple in transmission structure, and the power generation efficiency of the generator is high, so that energy consumption is reduced, the axial arrangement space of the transmission is reduced, and the difficulty of the mounting process of parts in the transmission is reduced.

Description

Technical field [0001] The present invention belongs to the field of hybrid technology, and is related to a mixing structure, and more particularly to a DMT dual motor hybrid transmission. Background technique [0002] The hybrid drive system is a hybrid drive system with pure power drive, pure engine drive, and hybrid driving capability. It is mainly to control each mode switching through a transmission. Existing transmission is typically composed of an engine, a flywheel, a clutch, a generator, a drive motor, a differential assembly. The output of the engine is a crankshaft, and the flywheel is rigidly attached to the crankshaft, and the generator and the drive motor are typically joined together by the shaft sleeve, and then connected between the flywheels, such a connection structure When the engine is operated When the clutch is disconnected, the generator is uncomfortable, which cannot be utilized for the kinetic energy of the engine, resulting in a higher energy consumptio...
