Embodiment Construction

[0017] like figure 1 As shown, the time-sharing four-wheel drive parallel hybrid drive system is arranged between the first automobile axle 1 and the second automobile axle 2 . In this embodiment, the first automobile axle 1 is the front axle of the automobile, and the second automobile axle 2 is the rear axle of the automobile. Certainly, the first automobile axle is 1 automobile rear axle, and the second automobile axle 2 is also a feasible scheme for automobile front axle.

[0018] The drive system includes an engine 3, a storage battery 4, and a first motor 5 and a second motor 6 capable of converting electrical energy and mechanical energy. Wherein, the storage battery 4 is a battery pack. The engine 3 is connected with the first automobile axle 1, and an engine controller 7 capable of controlling the operation of the engine 3 is connected on the engine 3, and can drive the first automobile axle 1 to work when the engine 3 works. The second motor 6 is connected with th...

Abstract

The invention provides a time-division 4-wheel drive (4WD) parallel hybrid driving system belonging to the technical field of automobiles. The invention solves the problem that the conventional fuel-electric 4WD hybrid automobile power system has low energy utilization rate. The time-division 4WD parallel hybrid driving system comprises an engine, a storage battery and first and second motors capable of performing conversion between electric energy and mechanical energy; the engine is connected with a first axle; an engine controller is connected to the engine; the engine can drive the first axle to work during work; the second motor is connected with a second axle; a second motor controller is connected to the second motor; the first motor is connected between the engine and the first motor controller; the first motor can charge the storage battery under the driving of the engine when the engine is in a working state; and the second motor can charge the storage battery when in a working state that mechanical energy is converted to electric energy. The invention has the advantages of strong power, high energy utilization rate, energy saving and environment protection.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to automobile power systems, in particular to a time-sharing four-wheel-drive parallel hybrid drive system. Background technique [0002] With the increasing demand for environmental protection and the increasing shortage of non-renewable resources such as petroleum, many car manufacturers are paying more and more attention to the research and development of energy-saving and emission-reducing models, and various hybrid vehicles are gradually coming out. Under the background of the existing technology, the four-wheel drive hybrid electric vehicle can meet the needs of energy and environmental protection to the greatest extent, so it has more market prospects. The configurations of hybrid electric vehicle power systems developed at present include series, parallel and hybrid. [0003] For the parallel four-wheel drive hybrid power system, people have carried out long-term explorati...
