Abstract

The invention relates to an input-power-split hybrid automatic transmission which is connected with an engine output shaft. The input-power-split hybrid automatic transmission comprises a housing, a dual-clutch module, a first motor, a third clutch, double planet rows, and a second motor, wherein the dual-clutch module, the first motor, the third clutch, the double planet rows and the second motor are disposed in the housing. The input end of the dual-clutch module is rigidly connected with the engine output shaft, and the output end of the dual-clutch module is connected with all of the first motor, the third clutch and the double planet rows. The third clutch is connected with both the first motor and the double planet rows. The double planet rows are connected with the second motor. Compared with the prior art, the input-power-split hybrid automatic transmission has the advantages that hybrid operating modes such as a serial drive mode and a direct gear parallel drive mode are added through three clutches, and the problems of insufficient starting and backing dive capability of the transmission are solved.

Description

technical field [0001] The invention relates to a hybrid transmission, in particular to an input power split type hybrid automatic transmission. Background technique [0002] An existing input power split hybrid transmission adopts a double planetary row, double motor (small motor and large motor) structure, no brake, no clutch. The engine is connected to the front planetary carrier through the torsional shock absorber, the small motor is connected to the front sun gear, the large motor is connected to the rear sun gear, the rear planetary carrier is locked to the gearbox housing, and the front and rear shared ring gears are connected together. The compounded power is transmitted to the output end. The advantages of the hybrid transmission are: simple mechanical structure, less difficulty in manufacturing and processing; the system only operates in a pure electric mode and a power split hybrid mode, less mode switching, and easy control. The disadvantages of the hybrid tra...
