Abstract

The invention belongs to the technical field of hybrid power automobiles, particularly relates to transmission devices and provides a seven-speed double-clutch hybrid power transmission device. The seven-speed double-clutch hybrid power transmission device comprises an engine input shaft (1), a damper (2), a K2 clutch (3), a K1 clutch (4), a first gear (5), a second gear (6), a twelfth gear (7), a third gear (8), a fourth gear (9), a fifth gear (10), an E synchronizer (11), a sixth gear (12), an F synchronizer (13), a seventh gear (14), a C synchronizer (15), an eighth gear (16), a B synchronizer (17), a ninth gear (18), a differential mechanism (20), a tenth gear (22), an eleventh gear (23), a decelerating planetary gear train (24), a motor (25), a first shaft (26) and a second shaft (27). According to the seven-speed double-clutch hybrid power transmission device, the complexity of a mechanism is reduced, transmission efficiency is improved, and economical efficiency of vehicle fuel oil is improved.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, in particular to a transmission device. Background technique [0002] Dual-clutch gearbox has the advantages of low cost, high transmission efficiency, power shifting, etc., and is increasingly widely used in the field of passenger vehicles. The hybrid power transmission system based on the dual-clutch gearbox can improve the fuel economy of the vehicle and realize pure electric driving. The effect is more obvious for urban congestion conditions. CN105697669 A discloses a 7-speed dual-clutch hybrid transmission, which adopts a 3-shaft arrangement. After the motor is configured with two gears, it is connected to a differential to realize dual-clutch transmission and hybrid functions. CN105383283A discloses a hybrid drive system based on a dual-clutch transmission, which also adopts a 3-axis arrangement, and a motor is connected to one of the gears to realize 7 forward gears and 3...
