Abstract

The present invention of a hybrid driving device comprises an engine, a startup dynamotor, a clutch, a speed changing mechanism, an electrical generator and an energy storage system. The energy storage system is electrically connected with the startup dynamotor and the electrical generator. A rotor shaft of the startup dynamotor is connected with an output shaft of the speed changing mechanism. And the output shaft of the speed changing mechanism is passed to a wheel by a transmission mechanism. Because a complicated power distributing mechanism is cancelled, the present invention of the hybrid driving device has a simple and compact structure and relatively flexible arrangement. In addition complex energy conversion does not exist, so the energy using efficiency is high and the overall performance is good. The vehicle power performance, fuel economy performance and emission performance and other aspect are all improved.

Description

technical field [0001] The present invention relates to a hybrid vehicle driving device using fuel and electric energy as power sources, the driving device has an engine and a motor generator, and the vehicle is driven by combining the two power sources in various situations. Background technique [0002] In today's world, human beings are facing two major challenges: energy scarcity and environmental degradation. Traditional automobiles are increasingly plagued by the oil crisis. Energy conservation and environmental protection have gradually become the development theme of the automobile industry. In recent years, hybrid electric vehicles with two different power sources to achieve reduced fuel consumption and emissions have been developed and applied, and put into commercial production and introduced to the market. Currently mass-produced hybrid vehicles include Toyota Prius, Toyota Crown, Honda Insight, Honda Civic, and so on. The known driving systems of hybrid electri...
