Problems solved by technology

The above-mentioned gearbox only realizes the deceleration transmission between the input shaft and the output shaft through a countershaft. The overall length of the gearbox is long, and it is difficult to apply to the transmission needs of vehicles with front transverse front drive. The structure is relatively large and there are few gears. , which is not conducive to making the engine work in the optimal area

Abstract

The embodiment of the invention discloses a hybrid automatic transmission. The hybrid automatic transmission comprises a first input shaft, a second input shaft, a first output shaft, a second outputshaft, a first clutch, a second clutch and a third clutch, wherein a plurality of driving gears are fixedly arranged on the first input shaft and the second input shaft; a plurality of driven gears and synchronizers are arranged on the first output shaft and the second output shaft; the driven gears are engaged with the corresponding driving gears; and the synchronizers are used for connecting thecorresponding driven gears into the first output shaft or the second output shaft. The transmission is compact in structure and high in efficiency, double clutch resources are utilized to the maximumextent, the manufacturing cost and research and development cost are reduced, the structure is simple, and processing is easy to implement.

Description

technical field [0001] The invention relates to an automatic transmission for vehicles, in particular to a hybrid automatic transmission. Background technique [0002] With the development of the automobile industry, the country pays more and more attention to environmental protection, and automobile emission regulations are becoming increasingly strict. Users have higher and higher requirements for vehicle safety, comfort and fuel economy. Hybrid vehicles, especially P2 Type hybrid drive has increasingly become the mainstream trend during the transition from traditional drive vehicles to pure electric drive vehicles. Based on the dual-clutch transmission, the separation clutch is added to connect the motor, and the hydraulic torque converter is canceled. The structure is relatively simple, the development cycle is short, and the cost Low, it can realize plug-in hybrid and oil hybrid. It not only has the advantages of dual-clutch transmission: during the gear shifting proce...
