Embodiment 1

[0023] Embodiment 1: as Figure 1 to Figure 5 Said, a commercial vehicle front axle beam, the front axle beam includes a "Z" section section 1, the bending strength of the "Z" section is 18% higher than that of the "I" section, and under the same axle load , "Z"-shaped cross-section beam is stronger than "I"-shaped cross-section beam, and the weight of the front axle beam is 7% lighter than that of the existing technology, which is more conducive to realizing the lightweight of the whole vehicle; "Z"-shaped cross-section part 1 There are leaf spring connecting part 2, journal connecting part 3 and fist part 4 arranged symmetrically on both sides in turn, and the leaf spring connecting part 2 and journal connecting part 3 are smoothly transitioned and connected.

[0024] Further, the cross section of the leaf spring connection part 2 to the journal connection part 3 smoothly transitions from the "Z" shape to the "I" shape; the cross section of the journal connection part 3 smoo...

Abstract

The invention relates to a front axle beam of a commercial vehicle. The front axle beam comprises a Z-shaped section part, plate spring connecting parts, journal connecting parts and fist parts are symmetrically arranged on the two sides of the Z-shaped section part in sequence, and the plate spring connecting parts and the journal connecting parts are in smooth transition connection. The front axle beam solves the problems that an existing front axle beam is large in weight, and fist parts are large in deformation.

Description

technical field [0001] The invention belongs to the technical field of commercial vehicle front axles, in particular to a commercial vehicle front axle beam. Background technique [0002] Vehicles are widely used in road transportation and engineering transportation. The front axle is an important load-bearing part of a commercial vehicle. Its load-bearing capacity determines the load-carrying capacity of the vehicle, and its weight affects the fuel consumption and other economic requirements of the vehicle. On the basis of satisfying the carrying capacity, the lighter the weight, the better the advantage. [0003] At present, the front axle beam on the market is widely used in the "I" shaped section. The "I" girder is heavy and consumes a lot of energy, which is unfavorable to the economy of the whole vehicle, and is also not conducive to energy saving and emission reduction. At the same time, when the vehicle brakes, the fist part of this type of structural beam also has...
