The invention relates to a light-weight driving front axle assembly which comprises a front axle shell, one end of an inner half axle in the front axle shell is connected with a main speed reducer assembly and a differential mechanism, and an inner spline of a half axle gear of the differential mechanism is connected with an outer spline of a movable joint at one end of a left constant-speed transmission shaft assembly. A fixed joint at the other end of the left constant-speed transmission shaft assembly is connected with a wheel-side disc brake assembly; the other end of the inner half shaft of the front axle shell is connected with a mechanical wheel, an inner spline of the mechanical wheel is connected with an outer spline of a movable joint at one end of a right constant-speed transmission shaft assembly, and a fixed joint at one end of the right constant-speed transmission shaft assembly is connected with a wheel-side disc brake assembly; an outer spline of the mechanical wheel is connected with an inner spline of a shifting fork sleeve, and a shifting fork head of an electric control automatic clutch assembly is embedded into an outer groove of the shifting fork sleeve. The front axle shell and the clutch retainer of the structure are of an aluminum alloy integral die-casting structure, the weight of a front axle assembly is reduced, the operation comfort of the whole vehicle is improved, and the oil consumption of the whole vehicle is reduced; the design of an electric control automatic half shaft clutch is adopted, and the free switching function between the 4X4 state and the 4X2 state is achieved.
