The invention belongs to the technical field of drive axles, and particularly relates to a wheel end power clutch device of a front drive axle with wheel edge speed reduction. The clutch device is mounted on the outer side surface of a shell of a wheel edge speed reducer assembly of the front drive axle and realizes meshing or separation of a clutch sleeve and a sun gear through rotating action. The device can adapt to conversion of four-wheel drive and two-wheel drive of the whole vehicle, when the whole vehicle is in a four-wheel drive state, the clutch sleeve and the sun wheel are locked, front axle drive is achieved, and the driving force of the whole vehicle is improved; when the whole vehicle is in a two-wheel drive state, the clutch sleeve is separated from the sun wheel, output ofthe front axle is cut off, reverse dragging of all rotating pieces is avoided, the running resistance of the whole vehicle is reduced, and the fuel economy is improved. The front wheel end cover doesnot need to be opened in the whole adjusting process, operation is easy and convenient, and wheel side gear oil leakage and impurity entering are avoided.

    本发明属于驱动桥技术领域,具体涉及一种带轮边减速前驱动桥的轮端动力离合装置,该离合装置安装于前驱动桥的轮边减速器总成的壳体外侧面上,通过转动动作实现离合套与太阳轮的啮合或分离。本发明可以适应于整车四驱与两驱的转化,在整车处于四驱状态时,锁紧离合套与太阳轮,实现前桥驱动,提高整车的驱动力;在整车处于两驱状态时,离合套与太阳轮分开,断开前桥的输出,避免了各个旋转件的反拖,降低整车的行驶阻力,提高燃油经济性。整个调节过程不需要打开前轮端盖,操作简便,并且不会导致轮边齿轮油泄露且容易进入杂质。
