The invention belongs to the technical field of power transmission, and particularly relates to a multi-mode oil-electric hybrid transmission device for a hybrid electric vehicle. According to the device, the modes of pure electric low-speed starting, parallel driving, series-parallel driving, fixed mechanical gear and the like are achieved through the engine, the two motors, the three planet rows, the three clutches and the two brakes. According to the device, the engine can normally work in a high-efficiency area, the motors can achieve braking energy recovery and effectively save energy and reduce emission, meanwhile, the two motors are low in power requirement, the size of a transmission device is reduced, the weight of a gearbox is reduced, and the manufacturing cost is reduced. According to the device, switching of multiple modes can be achieved, the requirement for the battery capacity is small, and the endurance mileage of an automobile is increased; the device is further provided with a mechanical gear, and the transmission efficiency can be improved.
本发明属于动力传动技术领域,具体涉及一种用于混合动力汽车的多模式油电混合传动装置。该装置通过发动机、两个电机、三个行星排、三个离合器和两个制动器来实现纯电低速启动、并联驱动、混联驱动和固定机械挡等模式。该装置可以使发动机常工作在高效区,电机可实现制动能量回收,有效节能减排,同时两个电机功率需求低,有利于减小传动装置的尺寸,减轻变速箱的重量,降低制造费用。该装置能够实现多个模式切换,电池容量需求小,提高了汽车的续航里程;该装置还拥有机械挡,可提高其传动效率。
