Spline flywheel assembly for double-clutch automatic transmission

Abstract

A spline flywheel assembly for a dual-clutch automatic transmission, comprising a flexible flywheel disc and a spline flywheel connected to the flexible flywheel disc, the spline flywheel adopts a disc-shaped structure, and its outer ring is provided with a plurality of bosses in the circumferential direction , the boss is provided with a threaded hole, and the center of the spline flywheel disc is provided with a spline hole; the flexible flywheel disc includes a connecting plate, and the connecting plate is riveted with the flexible disc through rivets, and the outer part of the connecting plate The flange sleeve is provided with a ring gear, and the connecting plate and the flexible disk are provided with crankshaft flange connection holes. The flexible disc is connected to the dual-clutch automatic transmission through the spline flywheel, replacing the hydraulic torque converter for power transmission; under the premise of ensuring the use function, different sizes can be designed according to the structure and arrangement between the engine and the transmission The spline flywheel does not affect the overall layout of the transmission system in the body when it is equipped with different models.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions in the automobile manufacturing industry, in particular to a spline flywheel assembly for a double-clutch automatic transmission. Background technique [0002] In the automobile power transmission system, the transmission is an essential component. The manual transmission is a step-variable transmission mechanism, which has the advantages of high efficiency, low cost, mature technology and wide application. The disadvantage is that it is difficult to shift gears, the power is interrupted when shifting gears, and the driver is required to be skilled in operation, so people hope to realize automation. [0003] With the rapid development of automobile technology, the application of automobile automatic transmission is more and more widely. At present, the most widely used automatic transmission adopts hydraulic torque converter, and it is also the automatic transmission with the long...

AI Technical Summary

Problems solved by technology

At present, the most widely used automatic transmission adopts hydraulic torque converter, and it is also the automatic transmission with the longest application history so far. It does not cut off the power shift, has the advantages of stable starting and shifting, and can adapt to the change of resistance torque. However, the AT shift action is sluggish, so the acceleration is slow, and there is a jerk feeling, which makes driving less enjoyable

In addition, AT has low transmission efficiency and high fuel consumption
