Description

Technical Field

[0001] This utility model relates to the field of clutch technology, and more specifically, to an automatic transmission dual-clutch clutch assembly. Background Technology

[0002] A dual-clutch transmission (DCT) is an advanced transmission system that combines the efficiency of a manual transmission with the convenience of an automatic transmission. In a DCT, two clutches control the odd and even gears respectively, resulting in smoother and faster gear changes, and providing better fuel economy and driving experience.

[0003] However, in existing dual-clutch automatic transmissions (DCTs), although high shifting efficiency and driving experience have been achieved, the clutch assembly temperature becomes excessively high during prolonged operation or high-load operation. This not only reduces the working efficiency of the clutch components but may also accelerate wear and even lead to premature failure. In addition, under complex road conditions, the potential damage to the internal structure of the clutch from external impacts and vibrations is also a major hidden danger.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
