The invention discloses a two-gear dual-clutch hybrid power system and a hybrid power vehicle. The system comprises an inner input shaft, an outer input shaft, an intermediate shaft, a differential and a motor, a first-gear driven gear, a second-gear driven gear and a normally engaged gear are fixedly connected to the intermediate shaft; the inner input shaft is connected with an engine through afirst clutch; the outer input shaft is connected with the engine through a second clutch; the outer input shaft is fixedly connected with a first-gear driving gear; the first-gear driving gear is meshed with the first-gear driven gear, the inner input shaft is fixedly connected with a second-gear driving gear, the second-gear driving gear is meshed with the second-gear driven gear, the normally-meshed gear is meshed with a main reduction gear of the differential mechanism, and a motor transmission mechanism is arranged between the motor and the differential mechanism and used for transmittingpower of the motor to the differential mechanism. Two gears are used, a synchronizer is omitted, gear switching is performed through the double clutches, torque supplementing is conducted on the motorin the gear shifting process, smooth gear shifting is guaranteed, the transmission efficiency is high, the space is small, and the whole vehicle is easy to arrange.

    本发明公开了一种两档双离合混合动力系统及混合动力车辆,包括内输入轴、外输入轴、中间轴、差速器以及电机,中间轴上固联有一档从动齿轮、二档从动齿轮和常啮合齿轮,内输入轴通过第一离合器与发动机连接,外输入轴通过第二离合器与发动机连接,外输入轴上固联有一档主动齿轮,一档主动齿轮与一档从动齿轮啮合,内输入轴上固联有二档主动齿轮,二档主动齿轮与二档从动齿轮啮合,常啮合齿轮与差速器的主减速齿轮啮合,电机与差速器之间设有电机传递机构,用于将电机的动力传递至差速器。本发明使用两个档位,取消同步器,利用双离合器进行档位切换,电机在换挡过程中进行补扭,保证换挡平顺、传动效率高,且空间小,整车易于布置。
