The invention discloses a double-clutch automatic transmission, a control method and a power system, and belongs to the technical field of transmissions.The double-clutch automatic transmission comprises double clutches, a main box and an auxiliary box; the main box comprises a first input shaft, a second shaft, a second input shaft, an intermediate shaft and a gear shifting gear set. The first input shaft and the second input shaft are coaxially arranged in a sleeved mode, the input end of the first input shaft and the input end of the second input shaft are connected with the double clutch, and the double clutch is used for transmitting power of an engine to the first input shaft or the second input shaft. The middle shaft and the second shaft are arranged in parallel, the second shaft and the first input shaft are coaxially arranged, and the output end of the second shaft is connected with the auxiliary box. According to the double-clutch automatic transmission, a plurality of gears are formed by controlling the combination state of a plurality of gear shifting gear sets, one of every two adjacent gears can be in the in-gear state, the in-gear state is combined with the double clutches to conduct power transmission, the other gear is in the pre-gear-engaging state, and by switching the combination state of the double clutches, the power transmission efficiency is improved. And gear shifting without power interruption is realized.
本发明公开了一种双离合器自动变速器、控制方法及动力系统,属于变速器技术领域,包括双离合器、主箱和副箱;所述主箱包括第一输入轴、二轴、第二输入轴、中间轴和换档齿轮组;所述第一输入轴和第二输入轴同轴套设,第一输入轴和第二输入轴的输入端分别与双离合器连接,双离合器用于将发动机的动力传递至第一输入轴或第二输入轴;所述中间轴与二轴平行布置,所述二轴与第一输入轴同轴设置,二轴的输出端与副箱连接;该双离合器自动变速器通过控制多个换档齿轮组的结合状态形成多个档位,并能够使相邻两个档位中的一个档位处于在档状态,在档状态的档位与双离合器结合进行动力传递,另一个档位处于预挂档状态,通过切换双离合器的结合状态,实现无动力中断换档。
