Abstract

The present invention relates to automobile drive system, and aims at providing one kind of parallel mixed gas-electricity automobile power system, which includes one clutch; one speed variator; one differential gear; one half axis; one first drive wheel assembly with gas storage, gas pipeline, main control valve, pneumatic engine connected to the clutch, etc; one second drive wheel assembly with motor, control system, power cell, connecting cables, etc; one central controller connected to the pneumatic drive system and the electric drive system; one front axle connected to the first drive wheel assembly; and one second axle connected to the second drive wheel assembly. The automobile drive system of the present invention has high performance, low cost, pneumatic engine serving as the auxiliary drive system, several operation modes and energy recovery.

Description

technical field [0001] The present invention relates to an automobile drive system, more specifically, the present invention relates to a parallel gas-electric hybrid vehicle power system. Background technique [0002] The continuous soaring of fuel prices and the increasing environmental pollution caused by fuel vehicles have made countries all over the world step up the research and development of new energy vehicles. As a new energy vehicle, electric vehicles have received considerable attention, but due to the high price of electric vehicles, short driving range, and short battery life, it is difficult for them to compete with fuel vehicles. [0003] In order to improve the competitiveness of electric vehicles and promote their industrialization process, it is one of the more effective means to optimize the existing electric vehicles in view of some problems existing in the use of electric vehicles. During the use of pure electric vehicles, there are large current chang...

AI Technical Summary

Problems solved by technology

Since this device adopts the arrangement of alternate work of pneumatic and electric, although the service life of the battery can be improved to a certain extent, since the energy storage of the whole system comes from the battery, the energy of the battery needs to be converted into the pressure energy of compressed air, and then Converting into mechanical energy will consume more energy than using only electric devices. If this power device is applied to vehicles, under the same battery capacity, the result can only be to reduce the driving range of electric vehicles, and the intermediate energy conversion In the process, an air compressor must be added, which complicates the structure of the entire power system.
