Embodiment 1

[0026] A two-mode hybrid transmission such as figure 1 As shown, it includes double planetary row 1, first motor E1, second motor E2, first clutch C1, second clutch C2, brake B, input shaft 2, output shaft 3 and differential 4; as figure 2 As shown, the double planet row 1 includes the ring gear R, the planet carrier C, the front planet P1, the rear planet P2, the front sun gear S1 and the rear sun gear S2. The outer diameter of the rear planet P2 is large tooth width and small index circle. The outer diameter of the front sun gear S1 is smaller than that of the rear sun gear S2, and the outer diameter of the front sun gear S1 is about 40mm. The outer diameter of the rear sun gear S2 is about 52mm; the front planet P1 and the rear planet P2 are sequentially installed on the planet carrier C, and the front planet P1 meshes with the front sun gear S1 and the ring gear R respectively to form a front gear The rear planet P2 meshes with the front planet P1 and the rear sun gear S...

Abstract

The invention provides a dual-mode hybrid power transmission device. The dual-mode hybrid power transmission device comprises a dual-planet row, a first motor, a second motor, a fist clutch, a second clutch, a brake, an input shaft, an output shaft and a differential mechanism. The dual-planet row comprises a gear ring, a planet carrier, a front row planet, a rear row planet, a front row sun gear and a rear row sun gear. The front row planet, the front row sun gear and the gear ring are engaged to form a front row gear train. The rear row planet, the front row planet and the rear row sun gear are engaged to form a rear row gear train. A rotor of a first motor is connected to the front row sun gear, the break is arranged between the first motor and the front row sun gear, a rotor of the second motor is connected to the rear row sun gear via the second clutch, the gear ring is connected to the differential mechanism via the first clutch, and the differential mechanism is connected to the output shaft. The first clutch is further connected to the fifth gear. The planet carrier is connected to the input shaft via a torsion damper. The dual-mode hybrid power transmission device is compact in structure, and good in performance of transmission.

Description

technical field [0001] The invention relates to a power transmission device, in particular to a dual-mode hybrid power transmission device. Background technique [0002] In recent years, with the vigorous promotion of the national new energy vehicle strategy and the increasing awareness of energy conservation and emission reduction among the people, the hybrid vehicle industry has shown a momentum of vigorous development. As its core component, the power coupling device has become the research and development focus of various manufacturers. [0003] The most representative products of foreign manufacturers include Toyota's THS hybrid system and GM's dual-mode hybrid system. THS adopts a single planetary row input power splitting structure, which divides the input power into a mechanical path and an electric path, and finally converges at the output end. This structure is a single-mode system. When the input and output speed ratio of the transmission is smaller than the mec...
