The variable speed driving system of the hybrid power vehicle is mainly characterized in that a speed change device is not installed behind an engine, and power is directly transmitted to a drive axle through a transmission shaft, or when the engine is transversely arranged on the drive axle, the power is transmitted through a tooth-shaped chain, so that the power of the engine can be transmitted to wheels only through one-stage gear speed reduction, and the power transmission efficiency is improved. The highest transmission efficiency is achieved, the torque borne by a transmission system is reduced, and the weight and cost are reduced; medium-speed and low-speed driving of the vehicle is mainly completed by a speed change device and a motor on a drive axle; the invention relates to an engine retroverted multi-output-end planetary gear set speed change device and a drive axle speed change device, so that a variable speed driving system is more energy-saving, and the cost is reduced.
本发明混合动力车辆的变速驱动系统主要内容是发动机后不安装变速装置,动力直接由传动轴传递至驱动桥,或在发动机横置于驱动桥上时,由齿形链传递动力,使发动机动力可以只经过一级齿轮减速就可以传递到车轮,达到最高的传递效率,并且减少传动系统承载的扭矩,减少重量和成本;车辆中、低速驱动主要由驱动桥上的变速装置和电动机完成;发明内容涉及到发动机后倾、多输出端行星齿轮组变速装置、驱动桥变速装置,使变速驱动系统更加节能,并且降低成本。
