The device comprises a first motor with an electric and/or power generation function and capable of inputting power or outputting power, a second motor with an electric and/or power generation function and capable of inputting power or outputting power, a single planetary row mechanism with a differential or speed change function and capable of transmitting power of an engine and/or the power of the first motor to a speed change output mechanism after differential or speed change, a speed change output mechanism with a speed change function and capable of transmitting the power of the single planetary row mechanism to a differential mechanism according to a predetermined speed ratio, the differential mechanism and a housing,and a variety of pure electric and hybrid power driving modes are achieved. The novel hybrid power transmission device has the advantages of high integration degree, simple structure, low control difficulty and multiple working modes.

Description

technical field [0001] The invention relates to the drive field of electromechanical hybrid vehicles, in particular to a novel hybrid transmission device. Background technique [0002] Due to the aggravation of the world's environmental and energy problems caused by traditional fuel engine vehicles, and the adjustment of new energy vehicle policies in various countries around the world, major automobile companies are actively developing energy-saving and environmentally friendly vehicles. The hybrid power system has become a feasible technical solution to solve automobile energy consumption and environmental pollution at this stage, and its core power transmission device has become the focus of research and development by various companies. [0003] At present, most of the hybrid schemes use multiple single-planetary rows in series or in parallel, but the fuel-saving efficiency is limited. For example, Chinese patent application number CN 201110405238 discloses a transmissi...
