Abstract

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.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an I-beam front axle structure of a commercial vehicle. Background technique [0002] The front axle is a device that transmits the force between the frame and the front wheel and the bending moment and torque generated by it. It is mainly composed of four parts: the front axle, the steering knuckle, the kingpin and the hub. The front axle is an extremely important load-carrying part of the automobile front axle, and the front axle of the prior art is I-shaped in cross section except two ends, so the front axle is called the I-beam again. [0003] The I-shaped front axle of the prior art has disadvantages such as large front axle mass and excess strength. As the requirements for light weight, comfort and safety become higher and higher, it is necessary to optimize the front axle and front axle. Contents of the invention [0004] The object of the present invention is to pro...
