Problems solved by technology

[0003] Pure electric vehicles have the following disadvantages: 1. The capacity of the battery is limited, the continuation time is relatively short, and the charging time is relatively long; 2. The torque is small and the climbing ability is weak; 3. During driving, if the battery part is abnormal 4. The battery is powered by a single power source, which causes the battery to be continuously discharged for a long time during use, which has a great impact on the service life of the battery
[0004] Although hybrid electric vehicles solve the shortcomings of pure electric vehicles, they also have many shortcomings: 1. The efficiency of force transmission is low and the energy loss is large; 2. Power switching is troublesome, and it needs to be controlled by an operating mechanism The pulling out and meshing of gears is noisy, the switching speed is slow, and improper operation may easily cause gear wear; 3. Large volume and high cost

Abstract

The invention relates to a driving device of a gas-electric hybrid vehicle. The driving device comprises an electromotor and an engine, wherein the output shafts of the electromotor and the engine are fixedly connected with a left half shaft and a right half shaft of a first differential mechanism respectively, an unilateral bearing is arranged on each of the left half shaft and the right half shaft of the first differential mechanism, and a driven gear on the first differential mechanism gear rack is connected with a variable-speed gear. The driving device is reasonable in structure design, convenient to use, high in force transmission efficiency, small in energy loss, quick and convenient in power switching, small in switching noise and size and low in costs.

Description

technical field [0001] The invention relates to a drive device for a hybrid electric vehicle. 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. Electric vehicles have outstanding performances such as energy saving and environmental protection, making them gradually replace traditional cars as an important means of transportation. For now, electric vehicles are basically divided into pure electric vehicles and hybrid electric vehicles. [0003] Pure electric vehicles have the following disadvantages: 1. The capacity of the battery is limited, the continuation time is relatively short, and the charging time is relatively long; 2. The torque is small and the climbing ability is weak; 3. During driving,...
