The invention provides an eight-speed double-clutch automatic transmission and a vehicle. The eight-speed double-clutch automatic transmission comprises two output shafts, a reverse gear shaft and twoinput shafts connected to an engine through clutches. Four odd-level driving gears are arranged on the first input shaft. The third-level and five-level gears or the fifth-level and seventh-level gears both belong to the driving gears. Four odd-level driven gears are arranged on the two output shafts in pairs correspondingly. In the direction far away from the engine, an eighth-level driving gear, a second-level driving gear, a fourth-level driving gear and a sixth-level driving gear are arranged on the second input shaft. A reverse driving gear connected with a second-level driven gear, a second-level driven gear and a fourth-level driven gear are arranged on the first input shaft in sequence. An eighth-level driven gear and a sixth-level driven gear are arranged on the second output shaft in sequence. A reverse driven gear is arranged on the reverse gear shaft. Synchronizers are arranged on the two output shafts and the reverse gear shaft. The eight-speed double-clutch automatic transmission outputs power of all the driven gears to the corresponding shafts through the five synchronizers and is small in axial length, simple and compact in structure, low in manufacturing cost andhigh in transmission efficiency.
本发明八速双离合器式自动变速器及车辆,包括两根输出轴、倒档轴及各自通过离合器连接于发动机的两根输入轴;四个奇数档的主动齿轮设于第一输入轴上,三五档或者五七档共用主动齿轮,四个奇数档的从动齿轮两两分设于两个输出轴上;沿远离发动机的方向:第二输入轴上设有八、二和四六档主动齿轮,第一输出轴上依次设有与二档从动齿轮联结的倒档主动齿轮及二、四档从动齿轮,第二输出轴上依次设有八、六档从动齿轮;倒档轴上设有倒档从动齿轮;两根输出轴和倒档轴上设有同步器,通过五个同步器将相应各档从动齿轮的动力输出至相应轴上。轴向尺寸短,结构简单、紧凑,制造成本低,传动效率高。
