Abstract

The invention belongs to the technical field of hybrid power automobiles, and particularly relates to a transmission device. The dual-mode hybrid power transmission device comprises an engine input shaft, a torsional damper, a Lavina planetary mechanism planetary carrier, a Lavina planetary mechanism first sun wheel, a Lavina planetary mechanism gear ring, a Lavina planetary mechanism second sun wheel, a first gear, a first motor, a first brake, a second motor, a second gear, a first clutch, a second clutch, a differential, a speed reduction gear, a fourth gear, a fifth gear, a sixth gear and a one-way clutch. The dual-mode hybrid power transmission device is compact in structure and high in transmission efficiency; two mechanical gears can be achieved, and the transmission efficiency is high, and the one-way clutch is arranged, an engine is prevented from rotating reversely, and under the pure electric working condition, an automobile can be driven through powers of the two motors at the same time.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, in particular to a transmission device. Background technique [0002] Hybrid power transmission is the research and development focus of various manufacturers in the national new energy vehicle strategy. All major automobile companies are actively developing hybrid power transmissions. Among them, the deep hybrid power transmission in the form of power split has more obvious energy-saving effect and is the most The representative product is THS of Toyota Corporation. The THS adopts the single-mode split-speed-combination-torque power split (output split) form of a single planetary row. It has a simple structure, but requires a large motor torque and power, and requires a high motor speed. When in the high-speed hybrid working condition, when the speed ratio of the transmission device is greater than the mechanical point speed ratio, the power cycle of the planetary row will occu...
