Problems solved by technology

The disadvantage of this kind of flexible disk with stress holes on the web plate is that it cannot meet the sealing and dustproof requirements of new cars, and the debris and dust in the clutch chamber will reach other parts of the powertrain through the stress holes of the flexible disk. , and affect the working efficiency and working life of the powertrain

Abstract

The invention relates to a flexible disc, an electrically-driven transmission assembly with the flexible disc and an automobile. The flexible disc is used for power transmission between an automobile engine and an electrically-driven transmission. An engine crankshaft connection portion is arranged at a position, close to the center, of the flexible disc; a clutch friction disc fixing portion is arranged at a position, close to the outer side, of the flexible disc; the flexible disc is circumferentially provided with a non-transparent ring stress compensation portion between the engine crankshaft connection portion and the clutch friction disc fixing portion. The flexible disc is reasonable in structure, special dustproof requirements of the electrically-driven transmission can be met while vibration resistance is realized, and production efficiency of the flexible disc is improved. In addition, by application of the flexible disc structure, flexible disc production and manufacture procedures and process sequences are reduced, and manufacturing cost is reduced.

Description

technical field [0001] The present invention relates to a technical field of power transmission; more specifically, the present invention relates to a flexible disc used for power transmission between an automobile engine and an electric drive transmission (EDU). [0002] Further, the present invention also relates to an electric drive gearbox assembly and a vehicle with such a flexible disk. Background technique [0003] With the development of automobile technology and combined with specific types of automobiles, the connection form between the engine and the gearbox of the automobile is also constantly changing. [0004] For example, the transmission system of a heavy-duty truck is generally rigidly connected, especially the power transmission between the engine and the gearbox, which is generally realized by inserting the input shaft of the gearbox into the input end of the crankshaft of the engine through a spline connection. In this case, the rotational vibration and ...
