The invention relates to an automobile front axle, in particular to an automobile front axle with a protruding bottom casting structure, comprising a crossbar and two cantilevers. Each of both ends of the crossbar is provided with a car-frame support, each end of the crossbar is connected with one of the cantilevers, and each cantilever is provided with a main pin hole. The upper surface of the crossbar is provided with a relief dent passing through a front surface to a rear surface, and the relief dent is disposed between the two car-frame supports. The lower surface of the crossbar is provided with a protruding bar aligning to the relief dent. The crossbar and the cantilevers forming a whole are of forging structures, and each of the front and rear surfaces of each cantilever is provided with a steering protecting block. The automobile front axle with the protruding bottom casting structure has an integrated structure of the crossbar and the cantilevers and excellent steering crash resistance, and solves the problems of lower rate of good products and higher fuel consumption caused by improving shock resistance via increasing the cross-sections of cantilevers in the current front axle manufacturing.
