Embodiment Construction

[0032] It can be known from the background technology that the current P2 mode hybrid power system has a large energy loss.

[0033] Please refer to figure 1 , figure 1 It is a partial structure diagram of a hybrid power system.

[0034] As shown in the figure, the hybrid power system includes a motor, a first clutch 1, a second clutch 2, the left end is connected to the engine 5, and the right end is connected to the gearbox 4. In the hybrid power output mode, because the engine 5 and the motor 3 share the same output shaft, the engine 5 and the motor 3 have the same speed. Because the engine 5 and the motor 3 operate in different speed ranges, the engine 5 and the motor 3 share the same output The shaft also restricts that the speeds of the engine 5 and the motor 3 must be equal. This leads to the fact that when the speed of the output shaft meets the speed range of the engine 5 to operate efficiently, the motor 3 cannot operate efficiently. Similarly, when the output shaft When...

Abstract

The invention discloses an automobile and a hybrid power system. The hybrid power system comprises a planet gear set, an engine, a motor, a gearbox, a first clutch and a second clutch, wherein the planet gear set comprises a sun wheel, a planet carrier and a gear ring; the engine comprises an engine output shaft, wherein the engine output shaft is in anti-torque connection with one of the sun wheel, the planet carrier and the gear ring; the motor comprises a motor output shaft, wherein the motor output shaft is in anti-torque connection with one another of the sun wheel, the planet carrier andthe gear ring; the gearbox comprises a gearbox input shaft, wherein the gearbox input shaft is in anti-torque connection with one another again of the sun wheel, the planet carrier and the gear ring;the first clutch is arranged on any two of the sun wheel, the planet carrier and the gear ring; and the second clutch is arranged between a shell of the hybrid power system and one of the sun wheel,the planet carrier and the gear ring. According to the embodiment of the automobile and the hybrid power system, the engine and the motor can operate at respective high-efficiency speed interval, so that energy loss is saved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of automobile technology, in particular to an automobile and a hybrid power system. Background technique [0002] A hybrid vehicle refers to a vehicle whose drive system is composed of two or more single drive systems that can operate at the same time. The power of the vehicle comes from a hybrid power assembly with at least two power units. Hybrid vehicles combine internal combustion engines, electric motors and batteries, which can take advantage of the advantages of internal combustion engine vehicles and electric vehicles, and are one of the effective ways to reduce oil consumption and carbon dioxide emissions. [0003] The power provided by the internal combustion engine or the electric motor is first transmitted to the transmission mechanism, which adjusts the torque output by adjusting the transmission ratio, and finally transmits the power to the wheels. [0004] P2 mode hybrid is an arrangem...
