Abstract

The invention belongs to the technical field of hybrid power automobiles, and particularly relates to a power transmission device. The forward wheel drive dual-mode hybrid power transmission device comprises an engine input shaft (1), a torsional damper (2), a first gear (3), a power distribution planetary mechanism, a planetary mechanism output gear (4), an input shaft (5), an output shaft (6), a second gear (7), a third gear (8), a differential (9), a shell (10), a first electric motor (E1), a second electric motor (E2), a second electric motor shaft (11), an output gear (13), a fourth gear (14), a clutch mechanism and a one-way clutch (18). According to the forward wheel drive dual-mode hybrid power transmission device, the axial dimension of the transmission device is decreased, the torque and power requirements of the electric motors are lowered, the transmission efficiency is high, and under the pure electric working condition, an automobile can be driven through the first electric motor and the second electric motor at the same time.

Description

Technical field [0001] The invention belongs to the technical field of hybrid vehicles, and particularly relates to a power transmission device. Background technique [0002] Hybrid power transmission is the research and development focus of various manufacturers in the national new energy vehicle strategy. Major automobile companies are actively researching and developing hybrid power transmission. Among them, the deep hybrid power transmission in the form of power split has more obvious energy-saving effects. The representative product is Toyota's THS. THS adopts a single planetary row of single-mode split-speed torque power split (output split) form, simple structure, but the required motor torque and power are relatively large, and the motor speed requirements are relatively high. When in a high-speed mixed operating condition and the gear ratio is greater than the mechanical point gear ratio, the planetary gear will circulate in power, which will affect the transmission eff...
