The invention relates to a hybrid power variable-speed driving system, a driving axle and a vehicle, provides a hybrid power driving axle suitable for a commercial vehicle with a long-stroke requirement, and mainly aims to weaken or cancel a gearbox behind an engine, transmit power to the driving axle through a transmission shaft, provide efficient power direct drive and provide main power for medium-speed and high-speed running of the vehicle. The power redundancy, the size, the weight and the cost required by the power assembly are greatly reduced, and the torque borne by the transmission shaft and the main speed reducer is greatly reduced. The motor is installed on the drive axle and mainly provides medium-low-speed, short-distance and empty running, kinetic energy recovery, climbing, overtaking and the like, the capacity needed by a battery is small, and the battery can be charged through an existing charging pile. Power of the engine and power of the motor can respectively drive different drive axles according to needs and can also jointly drive the same drive axle, at the moment, the power of the engine can be changed through the motor transmission on the drive axle, and applicability of the engine is improved.
本发明为混合动力变速驱动系统及驱动桥和其车辆,提供一种适用于具有长行程需求商用车的混动驱动桥,主要内容是减弱或取消发动机后的变速箱,动力由传动轴传递到驱动桥,提供高效动力直驱,为车辆中、高速行驶提供主要动力,极大降低了动力总成所需的动力冗余量、体积、重量和成本,极大降低传动轴、主减速器承载的扭矩。电动机安装在驱动桥,主要提供中低速、短程、空车行驶、动能回收、爬坡、超车等,电池所需容量较小,可以用现有充电桩充电。发动机动力与电动机动力根据需要可以分别驱动不同的驱动桥,也可以共同驱动相同的驱动桥,此时发动机动力可以通过驱动桥上的电动机变速器变速,增加发动机适用性。
