The invention provides an I-beam front axle structure of a commercial vehicle. The I-beam front axle structure comprises a front axle body, and the front axle body comprises a middle front axle body,an end front axle body and a bracket front axle body, wherein the end front axle body and the bracket front axle body are symmetrically and fixedly arranged on the two sides of the middle front axle body; the end front axle body is fixedly connected with the bracket front axle body, the bracket front axle body is located between the middle front axle body and the end front axle body, and a main pin hole is formed in the end front axle body. According to the I-beam front axle structure of the commercial vehicle, the position of the neutral surface of the I-beam section can be moved downwards, the overall tensile stress of the I-beam section is reduced, most of the section bears the pressure stress effect, the service life of the front axle is prolonged, the defect that an existing front axle is excessive in strength is overcome, meanwhile, the weight reduction requirement is met, and light weight is achieved.
本发明公开一种商用车工字梁前桥结构,包括前轴本体,所述前轴本体包括中部前轴本体及对称固定设置在所述中部前轴本体两侧的端部前轴本体和托座前轴本体;所述端部前轴本体与托座前轴本体固定连接,所述托座前轴本体位于所述中部前轴本体和端部前轴本体之间,所述端部前轴本体上开设有主销孔。本发明提供的商用车工字梁前桥结构,可以使工字梁截面的中性面位置下移,降低工字梁截面整体的拉应力,使得大部分截面承受压应力作用,提高前桥寿命,解决现有前桥存在的强度过剩的缺点,同时保证减重的要求,实现轻量化。
