Abstract

The invention discloses a multi-gear double-clutch transmission system. The multi-gear double-clutch transmission system comprises double clutches and a transmission; two output ends of the double clutches are correspondingly used for inputting power to an odd-number-gear transmission chain and an even-number-gear transmission chain of the transmission; the odd-number-gear transmission chain and the even-number-gear transmission chain can be locked at a suitable time so as to be integrated as a whole; the transmission comprises driving shafts and driven shafts; and gear speed-change transmission structures are correspondingly formed between the driving shafts and between the driven shafts both. The power system disclosed by the invention is relatively high in compactness and relatively shot in longitudinal length and has a relatively large number of gears.

Description

Technical field [0001] The invention relates to the field of auto parts, in particular to a dual-clutch automobile transmission and a control method thereof. Background technique [0002] Comfort, handling, efficiency and economy are all very important vehicle and transmission performance indicators. In the application of traditional manual transmissions and automatic transmissions, the above performance is just neglecting the other. Choosing high controllability and high efficiency and economy means low comfort; choosing high comfort means making some concessions in handling and economy. However, the adoption of a new type of dual-clutch transmission can satisfy the greatest extent People's comprehensive demand for the above performance. The dual-clutch transmission can provide high efficiency and higher maneuverability comparable to manual transmissions, and can meet people's needs for vehicle economy and driving entertainment; dual-clutch transmissions also have high comfort ...
