Abstract

The invention belongs to the technical field of power transmission, and particularly relates to a series-parallel oil-electric hybrid driving device suitable for a commercial vehicle. According to the device, modes of pure electric low-speed starting, series driving, parallel driving, series-parallel driving, fixed mechanical gear and the like are achieved through the engine, the two motors, the three planet rows, the three clutches and the three brakes. According to the device, the engine can normally work in a high-efficiency area, the motors can achieve braking energy recovery and effectively save energy and reduce emission, meanwhile, the two motors are low in power requirement, the size of a transmission device is reduced, the weight of a gearbox is reduced, and the manufacturing cost is reduced. According to the device, switching of multiple modes can be achieved, the requirement for the battery capacity is small, and the endurance mileage of the automobile is increased. The device is further provided with a mechanical gear, and the transmission efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and in particular relates to a hybrid hybrid driving device suitable for commercial vehicles. Background technique [0002] Due to the shortage of energy and the enhancement of public awareness of environmental protection, new energy and environmentally friendly vehicles are increasingly valued. However, due to technical constraints, for commercial vehicles, pure electric or fuel cell commercial vehicles are difficult to be fully promoted in a short period of time due to reasons such as short cruising range and difficulty in charging, so hybrid commercial vehicles are currently an ideal new energy source. Eco-friendly car choice. [0003] Compared with conventional vehicles and pure electric vehicles, the biggest difference between hybrid vehicles is the power system. Gasoline-electric hybrid is currently the mainstream form of hybrid power transmission. It is classified according to...
