Electromagnetic powder brake type co-rotating arm double planetary gear rows hybrid power device

Abstract

The invention discloses an electromagnetic powder brake type co-rotating arm double planetary gear rows hybrid power device. The device comprises an engine, an elastic damping disc, a first motor, a first planetary gear row, a second planetary gear row, a second motor, a first electromagnetic powder brake, a second electromagnetic powder brake, a third electromagnetic powder brake, a fourth electromagnetic powder brake and a two-stage parallel shaft gear drive differential-speed module. By selecting power on and off of the first electromagnetic powder brake, the second electromagnetic powder brake, the third electromagnetic powder brake, and the fourth electromagnetic powder brake, driving modes such as the engine single drive, the first motor single drive, the second motor single drive, the engine and the first motor combined ECVT drive, the motor and the second motor combined ECVT drive, the engine and the first motor and the second motor combined ECVT drive, and the first motor and the second motor combined ECVT drive are realized. The electromagnetic powder brake type co-rotating arm double planetary gear rows hybrid power device has the advantages of good oil-saving and electricity-saving performances, long service life, high transmission efficiency, small rotary inertia and high reliability.

Description

Technical field [0001] The invention relates to the field of power systems for vehicles, in particular to an electromagnetic powder brake type co-rotating arm double planetary row hybrid power device. Background technique [0002] With the continuous development of the global automotive industry, power plants for new energy vehicles have become a research hotspot for major auto companies and related universities, especially power plants for plug-in hybrid vehicles. For most hybrid power plants, the engine + clutch + motor + automatic transmission scheme or planetary gear coupler scheme is generally adopted. However, the above technical solutions all have the phenomenon that the motor rotor follows the rotation at high speed when the engine is driven at a high speed, resulting in a significant drop in system efficiency; at the same time, there are technical problems such as a single driving mode and low power and fuel saving effects. Summary of the invention [0003] The technical...
