Problems solved by technology

From the point of view of the current domestic hybrid electric vehicle transmission system, most of them only modify the drive system on the original vehicle, and most of the modified drive systems are in the form of series and parallel connections. The layout is not compact, and there are few working modes. The economy, emissions and power are limited, and it is difficult to meet the requirements of vehicles with large loads and large load changes

Abstract

The mixed power drive unit based on automatic mechanical speed variator has one brake, two clutches, one 4-gear mechanical automatic speed variator and one planet gear rank mechanism. The 4-gear mechanical automatic speed variator consists of four meshed gear pairs, two synchronizers, two shafts and one output shaft. By means of the control on two clutches and one brake, the present invention realizes the switching among fuel oil power source driving, electric power source driving and mixed power source driving. By means of the control on two synchronizers, the present invention realizes the switching among four gears. The present invention has the advantages of compact structure, much modes and mush gears.

Description

technical field [0001] The invention relates to a power drive device, in particular to a hybrid drive device based on a mechanical automatic transmission. Background technique [0002] Due to the current increasingly tense world energy and people's growing awareness of environmental protection, the requirements for vehicle safety, energy saving, and environmental protection are getting higher and higher. However, due to the bottleneck constraints of fuel cells, motors, and controls, pure electric vehicles and fuel cell vehicles cannot be mass-produced and practically used. Therefore, hybrid vehicles have become a more suitable choice to solve the above problems. [0003] Developing a good transmission system is the first step in the research and development of hybrid electric vehicles, so the method of power synthesis and the choice of structural form are directly related to the performance of future vehicles. From the point of view of the current domestic hybrid electric v...
