Double-clutch and double-motor hybrid power assembly with speed reducer module

Abstract

The invention discloses a double-clutch and double-motor hybrid power assembly with a speed reducer module. An engine, an elastic damping connector, a front single-plate clutch, a first motor, a rear single-plate clutch, a second motor and the speed reducer module of the double-clutch and double-motor hybrid power assembly are sequentially coaxially connected with one another; the speed reducer module is connected with a driving axle assembly; a vehicle control unit is connected with an energy storage power source, a first motor controller and a second motor controller, the first motor controller is further connected with the first motor and the energy storage power source, and the second motor controller is further connected with the second motor and the energy storage power source. The double-clutch and double-motor hybrid power assembly has the advantages that the front single-plate clutch and the rear single-plate clutch can be switched over without power interruption, are quick in response, small in structural volume, high in reliability and transmission efficiency and low in energy consumption and maintenance cost and are provided with simple control systems, chassis impact load of main driving motors can be effectively reduced or eliminated by the speed reducer module, accordingly, the power transmission efficiency of a new-energy vehicle can be effectively improved, energy management and matching can be optimized, the integral performance can be improved, and the like.

Description

technical field

[0001] The invention relates to the technical field of new energy vehicles, in particular to a dual-clutch dual-motor hybrid power assembly with a reducer module suitable for new energy vehicles. Background technique

[0002] With the continuous development of society and vehicle engineering technology, the number of vehicles is increasing. The energy consumption during the use of vehicles and the pollution of exhaust emissions to the environment have been highly valued by all walks of life. More and more countries and regions have introduced incentive policies for the development of new energy vehicles, especially the use of powertrains for large commercial vehicles plays an important role in actively promoting the development of new energy vehicles and related supporting industries and technologies. Currently, the technical routes adopted in the market are mainly hybrid technology and pure electric technology. Whether it is hybrid technology or pure electr...
