Title:
MULTI-MODE ELECTROMECHANICAL COUPLING TRANSMISSION DEVICE HAVING TWO MOTORS AND TWO PLANETARY GEAR SETS
Document Type and Number:
WIPO Patent Application WO/2020/125465
Kind Code:
A1
Abstract:
Disclosed is a multi-mode electromechanical coupling transmission device having two motors and two planetary gear sets. When compared to the THS system solution from Toyota and the CHS system solution from Corun, the present invention achieves, by means of disengaging or engaging a clutch C1, both input power division and compound power division, that is, providing two hybrid eCVT modes, thereby achieving high transmission efficiency by switching between these two hybrid modes. When compared to the second generation Voltec structure solution from General Motors, the present invention is further provided with an all-electric gear. A small gear ratio of an all-electric second gear reduces a peak rotational speed of a motor E1 or increases the maximal speed of a vehicle running entirely on electricity. The two motors are also arranged on the same side of the planetary gear sets to achieve a more compact structure.
