Problems solved by technology
[0007] Most of the current hybrid power systems mainly include internal combustion engines, generators, clutches, transmissions, power batteries, braking systems and vehicle automatic control systems, but their use costs are relatively high, and their driving range is relatively short. There is room for improvement in terms of fuel economy

The invention provides a hybrid power system which comprises a composite fuel storage device, a first energy conversion device, a second energy conversion device, a planetary gear transmission mechanism and four axial force transmission devices. The composite fuel storage device is connected with the first energy conversion device and the second energy conversion device, the planetary gear transmission mechanism comprises a sun gear, a gear ring, a machine frame and a planetary frame. One of the first energy conversion device and the second energy conversion device is connected with the sun gar through the first axial force transmission device, and the other of the first energy conversion device and the second energy conversion device is connected with the gear ring through the second axial force transmission device. The sun gear and the ring gear are connected with the machine frame through the third axial force transmission device and the fourth axial force transmission device respectively so as to be fixed or loosened. The hybrid power system is high in energy utilization rate, long in driving distance and flexible in work mode, and few pollutants are discharged.
Description
Technical field [0001] The invention belongs to the technical field of hybrid vehicles and relates to a hybrid power system. Background technique [0002] Hybrid electric vehicles have become the focus of current automobile development, and their advantages in energy saving and emission reduction have been widely valued by automobile companies and research institutions, and they have invested heavily in research and development, and many molded products have been put on the market. In the foreseeable future, it will be widely promoted and used as the mainstream direction of automobile development. [0003] At present, according to the connection mode of hybrid drive, hybrid power systems are mainly divided into the following three categories: [0004] The first is a series hybrid power system. Generally, the internal combustion engine directly drives the generator to generate electricity. The generated electrical energy is transmitted to the battery through the control unit, and the...
