Embodiment 1

[0053] figure 1 It is a schematic structural diagram of the power system of the hybrid electric vehicle provided by the present invention.

[0054] It should be noted that, in the following embodiments, the front axle drive refers to the front drive of the hybrid electric vehicle, and the rear axle drive refers to the rear drive of the hybrid electric vehicle.

[0055] refer to figure 1 , the power system of a hybrid electric vehicle provided in this embodiment includes: a front axle drive 120 , a rear axle drive 130 , a battery 110 and a monitoring module 100 .

[0056] Wherein, the monitoring module 100 is connected with the front axle drive 120 , the monitoring module 100 is connected with the battery 110 , and the monitoring module 100 is connected with the rear axle drive 130 . The battery 110 is connected between the front axle drive 120 and the rear axle drive 130 .

[0057] Optionally, the monitoring module 100 may be installed in the cab of the hybrid vehicle, or o...

Embodiment 2

[0069] This embodiment is carried out on the basis of the first embodiment, and based on the power system structure of the hybrid electric vehicle provided in the first embodiment, it can enable the hybrid electric vehicle to drive in the following multiple modes.

[0070] image 3 A schematic diagram of the power flow of the power system of the hybrid electric vehicle in the pure electric mode provided by the present invention. When the monitoring module 100 detects that the power value of the battery 110 is higher than the first preset value, as an achievable way, refer to image 3 , control the first clutch 2 to be disconnected, control the second clutch 3 to be closed, and the monitoring module 100 controls the first motor 4 to work in the driving mode, so that the power flow is sequentially passed through the first motor 4, the third gear 8, and the second gear by the battery 110 The second gear 7 and the second clutch 3 are transmitted to the wheels 17 of the front axle...

Abstract

The invention provides a dynamical system of a hybrid electric vehicle. The system comprises a front shaft drive, a back shaft drive, a battery and a monitoring module, the monitoring module is connected with the front shaft drive, the monitoring module is connected with the battery, and the monitoring module is connected with the back shaft drive, and the battery is connected between the front shaft drive and the back shaft drive; the front shaft drive comprises a first clutch, a second clutch, an engine, a first motor, a first gear, a second gear and a third gear, the first clutch is connected between an output shaft of the engine and a gear shaft of the first gear , the second clutch is connected between an input shaft of a retarder and a gear shaft of the second gear, a motor shaft ofthe first motor is connected with a gear shaft of the third gear, and the battery is connected with the first motor; the first gear is meshed with the second gear, and the second gear is meshed with the third gear. The dynamical system of the hybrid electric vehicle can solve the problem that the structure inside a compartment of a precursor engine is complex in an existing dynamical system of a hybrid electric vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile structure design, in particular to a power system of a hybrid electric automobile. Background technique [0002] A hybrid electrical vehicle (HEV) refers to a vehicle that is equipped with both a thermal power source (generated by a traditional gasoline engine or a diesel engine) and an electric power source (battery and electric motor). Compared with traditional power vehicles, HEV can reduce fuel consumption and emissions, which is conducive to reducing environmental pollution. Among them, the structure of the power system of the hybrid electric vehicle is the focus of designing the hybrid electric vehicle. [0003] In the power system of the existing hybrid electric vehicle, the front drive of the vehicle is generally equipped with an engine, a drive motor, a generator, and a multi-speed transmission. Further, by adding an electric drive rear axle, a hybrid four-wheel drive system is formed...
