Problems solved by technology

At present, three kinds of automatic clutches are mainly used in hybrid powertrains. One is the automatic clutch that separates or combines the dry clutch by pushing the shift fork release bearing through the cylinder; Technical problems such as short bearing life, complex control system, large structure volume, high machining accuracy, high failure probability, short life, and high maintenance cost
The second is an automatic clutch that realizes clutching by pushing multiple wet friction pairs through a hydraulic cylinder; however, there are technical problems such as large discharge resistance, low efficiency, complex hydraulic control components, and high maintenance costs with multiple wet friction pairs.
However, AMT has technical problems such as poor smoothness of shifting, inability to realize powerless intermittent shifting, long shifting time, complex control system, large structure volume, high machining accuracy, low reliability, and inability to realize semi-linkage drive.
Therefore, the above three types of clutches do not meet the performance matching requirements of the hybrid powertrain, resulting in technical problems such as low transmission efficiency of new energy vehicles, poor energy management and matching, and low powertrain performance.

Abstract

The invention discloses a dual-single-disc clutch and dual-motor hybrid power assembly, in which an engine, an elastic damping connector, a front single-disc clutch, a first motor, a rear single-disc clutch and a second motor are connected in sequence on the same axis; the second motor passes through The cardan shaft is connected with the drive axle assembly. The vehicle controller is respectively connected with the first energy storage power supply, the second energy storage power supply, the first motor controller, and the second motor controller; the first motor controller is also respectively connected with the first motor, the first energy storage power supply, the second The second energy storage power supply is connected; the second motor controller is also connected with the second motor and the second energy storage power supply respectively. The single disc clutch of the present invention has the advantages of no axial force on other parts, rapid clutching, long-term sliding and friction combination, small loss, small axial size, large transmission torque power, overload protection, adjustable speed ratio, and low cost. . The energy of the whole machine can be switched between the engine and the energy storage power supply, the matching is more reasonable, and recycling can be realized; the performance of the whole machine can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a double-single-disc clutch and double-motor hybrid power assembly 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 electric...
