Double-drive electrical plug-in hybrid power automobile

Abstract

The invention discloses a double-drive electrical plug-in hybrid power automobile. The automobile includes an engine, a transmission, a battery, an inverter, a driving control system, a transverse structural beam and two motors; the engine, the transmission, the battery, the inverter and the driving control system are installed in a cabin, the transverse structural beam is connected to a rear suspension, and the two motors are fixed to the two ends of the transverse structural beam respectively and connected with two rear wheels through two-section type driving shafts respectively; when the automobile stays in a starting state at a low speed, driving is completed by the two motors, and at that time, the two motors drive the two rear wheels through the two-section driving shafts respectively; when the speed reaches a set value, the driving control system emits a control instruction, driving is completed by the engine, and at that time, the engine directly drives two front wheels throughthe transmission. The automobile can fully utilize the advantages that the engine is high in rotation speed and capable of saving oil and the motor is low in rotation speed and capable of saving electric power, and therefore oil consumption can be substantially saved, and emission of the engine can be reduced; meanwhile, the automobile breaks the foreign technical barrier of driving systems, andreduces costs.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, in particular to a dual-drive plug-in hybrid electric vehicle. Background technique [0002] HEV is the abbreviation of Hybrid Electric Vehicle, that is, a hybrid vehicle. HEV is a compromise model between traditional vehicles and fully electric vehicles. It uses the internal combustion engine of traditional vehicles and the electric motor of fully electric vehicles for hybrid drive at the same time, reducing the demand for fossil raw materials and improving fuel economy, thereby achieving energy saving and emission reduction. The problem of the greenhouse effect. [0003] Different from existing hybrid models (such as Toyota hybrid models), many domestic first-class car manufacturers have launched electric models equipped with extended-range engines, which are called plug-in hybrid electric vehicles (PHEV for short). Take advantage of the rest at night to plug in the fully cha...

AI Technical Summary

Problems solved by technology

[0007] 1. Due to the efficiency of the generator, it cannot effectively reduce fuel consumption and engine emissions;

[0008] 2. The engine and the motor drive the front wheels at the same time, requiring a complex drive system, and the technology of these drive systems is often in the hands of foreign automobile manufacturers, there are technical barriers, and high technical costs need to be paid; at the same time, some models front and rear A drive shaft 1 needs to be set between the transverse axles to transmit the power of the front wheels to the rear wheels, and a differential gear 2 needs to be set between the transverse rear axles, resulting in a complex structure and high cost of the entire suspension system;

[0009] 3. Most of the motor-driven rear wheels use hub motors, and hub motors are more expensive than ordinary motors

[0010] 4. At present, AMT transmissions and DCT transmissions mastered in China have problems such as shaking, twitching and abnormal noise at low speeds
