The invention provides a single-gear hybrid power system and a vehicle. In the single-gear hybrid power system, as the first motor and the second motor adopt the scheme of parallel configuration and staggered configuration, compared with a hybrid power system described in the background technology, the axial size of the whole system is reduced. Moreover, the first motor and the engine are coaxially arranged, and the first motor and the second motor are arranged in parallel and in a staggered mode, so that the packaging space of the whole system is improved, and the single-gear hybrid power system is suitable for various vehicles. Furthermore, a second gear which is in transmission connection with a second motor all the time is located on a transmission path through which the engine and the first motor transmit torque to the intermediate shaft, structural layout of all parts in the transmission is facilitated, the engine, the first motor and the second motor transmit torque to the differential mechanism through the common intermediate shaft, and therefore the parts are saved, and cost is reduced. And the cost of the whole system is reduced.

    本发明提供了一种单挡混合动力系统及车辆。在该单挡混合动力系统中,由于第一电机与第二电机采用平行配置和错开配置的方案,因而与背景技术中说明的混合动力系统相比减小了整个系统的轴向尺寸。而且,第一电机与发动机采用同轴配置且第一电机与第二电机采用平行配置和错开配置的方案,还改善了整个系统的封装空间,使得本申请的单挡混合动力系统适用于各种车辆。进一步地,与第二电机始终传动联接的第二齿轮位于发动机和第一电机两者向中间轴传递扭矩的传递路径上,有利于变速器中各部件的结构布局,而且发动机、第一电机和第二电机经由公共的中间轴向差速器传递扭矩,因而节省了部件,降低了整个系统的成本。
