The invention relates to a commercial vehicle integrated axle with a speed change function and an energy recovery device, and belongs to the field of commercial vehicle integrated axles. The device comprises a speed reduction device, an energy recovery device and a differential device. A planetary reduction gear train is adopted in the speed reduction device, speed reduction and torque increase of an input shaft are achieved through the planetary reduction gear train, a driving gear and a gentle slope gear are arranged, the adaptive reduction ratio is provided for vehicle abrupt slope descending, and heating of brake components caused by frequent braking is avoided; the energy recovery device is provided with a generator, energy is recovered when the vehicle brakes, and the economical efficiency of the vehicle is improved; the differential device shunts the output torque of the speed reduction device to the output half shaft through the differential gear train, and differential is achieved. The integrated axle speed reducer has good engineering application value in the aspects of simplifying the structure of the integrated axle speed reducer and solving the safety problem caused by brake heat.

    本发明涉及一种带变速功能、含能量回收装置的商用车一体式车桥,属于商用车一体式车桥领域;其包括减速装置、能量回收装置、差速装置。其减速装置采用行星减速轮系,输入轴由行星减速轮系实现减速增扭,设置行驶挡和缓坡挡,为车辆陡坡下降提供相适应的减速比,避免频繁刹车导致刹车部件发热;能量回收装置设置发电机,在车辆刹车时回收能量,提高车辆的经济性;差速装置通过差速器轮系将减速装置的输出力矩分流到输出半轴上,实现差速。本发明在简化一体车桥减速器结构和解决刹车热导致的安全问题方面具有较好的工程应用价值。
