Embodiment Construction

[0074] figure 1 is a schematic structural diagram of a hybrid powertrain according to an embodiment of the present invention. Such as figure 1 As shown, the present hybrid powertrain includes an automatic transmission 20 , an engine 13 and an electric machine 11 . The automatic transmission 20 is used to provide different gear ratios to change the driving speed of the vehicle. The automatic transmission 20 includes a transmission case 10 , a multi-stage planetary gear, and an input shaft 1 . In this embodiment, the multi-stage planetary gears include a first planetary gear 21 and a second planetary gear 22 . It can be understood that the multi-stage planetary gears may also include three or more planetary gears. The engine 13 is used to provide power to the vehicle, and the output shaft of the engine 13 is in driving connection with the input shaft 1 of the automatic transmission 20 through the engine flywheel 12 . Engine flywheel 12 may be a dual mass flywheel. The moto...

Abstract

The invention discloses a hybrid power assembly with an automatic transmission and relates to the field of hybrid power of automobiles. The hybrid power assembly comprises the automatic transmission, an engine and a motor. The automatic transmission is used for providing different transmission ratios and changing the automobile traveling speed. The automatic transmission comprises a transmission housing, a multi-stage planetary gear and an input shaft. The engine is used for providing power for an automobile, and an output shaft of the engine is in transmission connection with an input shaft of the automatic transmission through a dual-mass flywheel. The motor is installed in the transmission housing, connected with or separated from the automatic transmission through a joint element, and used for cooperating with the engine to achieve recovery of the hybrid power and energy. According to the hybrid power assembly, the motor is arranged in the transmission housing, the automatic transmission is in transmission connection with the engine through the flywheel of the engine, the structure is compact, the weight is hardly increased, the dimension change is small, performance is advanced, and the oil saving effect is remarkable.

Description

technical field [0001] The invention relates to the field of vehicle hybrid power, in particular to a hybrid power assembly with an automatic transmission. Background technique [0002] According to environmental protection requirements, China's 2020 carbon dioxide emission limit is 117g / km; according to fuel consumption rate requirements, China's 2020 average passenger vehicle comprehensive fuel consumption limit is 5L / km. In order to meet the above requirements, hybrid vehicles have become the general trend. The current hybrid vehicle refers to an electric hybrid vehicle driven by electricity, oil and gas (gasoline, diesel or natural gas) or a mixture of electricity and oil and gas. [0003] The transmission of the hybrid electric vehicle can realize multi-gear speed change for the engine drive and the drive motor drive. There are typical parallel hybrids and series hybrids on the market today. In the parallel hybrid powertrain, the motor is connected in parallel to the...
