Problems solved by technology

[0011] To sum up, the use of simple automobile transmission devices, whether manual, automatic or continuously variable, cannot solve the three major energy-saving problems.
Although the electromechanical hybrid driving method has greatly improved the energy saving effect, the performance of the battery and the cost of the system have become the key to restricting its development, such as the realization of fast charging and discharging, the improvement of energy storage efficiency and the battery life. To be solved; in addition, the drive system is complex, the required electromechanical conversion control, battery pack and high-power motor are costly, and it is also difficult to achieve energy-saving transformation of nearly 800 million vehicles already in use around the world
The existing machine-hydraulic hybrid drive mode has not been able to overcome the defects of small specific energy and low transmission efficiency of the hydraulic system. The designed mechanism is complex and has a large volume and weight. Used on large motor vehicles driving in urban areas, the overall energy-saving effect of the system is not obvious

Description

technical field [0001] The invention relates to a power transmission, conversion, storage and use device for a motor vehicle, in particular to a motor vehicle power device capable of realizing stepless speed change, multiple power mixing and cycle drive, and mechanical-hydraulic-electrical integration. Background technique [0002] According to incomplete statistics, there are more than 800 million motor vehicles in the world, which consume more than 1 billion tons of oil every year and increase year by year. The greenhouse gas CO2 and various toxic substances emitted have caused increasingly serious environmental pollution and damage. At the same time, global oil resources are only available for human use for several decades. Therefore, due to the pollution and energy shortage caused by automobiles, automobile energy saving has attracted great attention and attention from all over the world. [0003] According to statistics from the U.S. Department of Energy, only 15% of t...
