The invention belongs to the technical field of motor vehicles, and particularly relates to a vehicle transmission system and a vehicle. The vehicle transmission system comprises an engine, a variablepump and a controller, the variable pump is connected with a first transmission assembly through a second transmission assembly, and the variable pump is connected with two driving devices; a controller is respectively connected with the variable pump, the first driving device and the second driving device; and the first transmission assembly is connected with a fifth transmission assembly, the first driving device is connected with the fifth transmission assembly through a sixth transmission assembly, and the second driving device is connected with a fourth transmission assembly through a third transmission assembly. According to the scheme, the variable pump, the first driving device, the second driving device and the engine are used in a mixed mode, the first driving device is controlled to adjust output torque and the second driving device is controlled to adjust rotating speed through transmission of all transmission assemblies, coupling of the rotating speed and the torque is achieved, stepless speed change is achieved, and the engine can work in the area with the highest efficiency at different rotating speeds.

    本发明属于机动车技术领域,具体涉及一种车辆的传动系统及车辆。本发明的车辆的传动系统包括发动机、变量泵和控制器,变量泵通过第二传动组件与第一传动组件相连接,变量泵分别与两个驱动装置连接;控制器分别与变量泵、第一驱动装置和第二驱动装置相连接;第一传动组件与第五传动组件连接,第一驱动装置通过第六传动组件与第五传动组件相连接,第二驱动装置通过第三传动组件与第四传动组件相连接。本方案中,通过变量泵、第一驱动装置、第二驱动装置和发动机的混合使用,通过各传动组件的传动,控制第一驱动装置调整输出扭矩和第二驱动装置调整转速,实现转速和转矩的耦合,达到无极变速,使发动机在不同转速下能工作在效率最高区域。
