Driving device of hybrid vehicle

Abstract

The present invention of a hybrid driving device comprises an engine, a starting generator, a clutch, a speed changing mechanism, an electrical generator and an energy storage system. The energy storage system is electrically connected with the starting generator and the electrical generator. A rotor shaft of the starting generator 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 that 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...

Problems solved by technology

[0008] In this kind of driving device, the power distribution mechanism must divide the power of the engine into mechanical and electrical circuits, in which the electrical channel needs to undergo the conversion of mechanical energy-electric energy-mechanical energy, which inevitably increases the loss of energy conversion

[0009] The drive device for hybrid electric vehicle invented by this patent application is only an arrangement scheme in which a reduction mechanism is added to the above-mentioned existing planetary gear set and used as a power distribution mechanism. It does not solve the problem of complex structure of the power distribution mechanism, high energy loss
