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, the engine and the first motor are in transmission connection with the second motor through different gear pairs and a common intermediate shaft, so that part of components are saved while transmission ratios of different torque transmission paths in the whole hybrid power system are easy to configure, and the cost is further reduced.

    本申请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,发动机和第一电机两者与第二电机通过不同的齿轮副与公共的中间轴实现传动联接,使得在易于配置整个混合动力系统中不同的扭矩传递路径的传动比的同时节省了部分部件,从而进一步降低了成本。
