AI Technical Summary

Technical Problem

The forces transferred from the axle head to the axle arm generate high stress levels, leading to punching deformation in the welded area, which compromises the structural integrity and durability of the axle.

Method used

A reinforcing bracket with perpendicular branches is integrated into the axle design, distributing forces over a wider area and reducing stress concentrations, thereby preventing deformation.

Benefits of technology

The reinforcing bracket effectively distributes forces, reducing stress levels and preventing deformation, enhancing the axle's structural resistance and durability.

Abstract

The invention relates to an axle (1) for a motor vehicle comprising: - a first axle arm (2); - a first axle head (8) comprising a mounting flange (13), a rear mounting wing (16) and a front mounting wing (15); and - a first reinforcing bracket (18) comprising a first arm (19) and a second arm (20) perpendicular to each other; the first arm (19) extending along the first axle arm (2) between the front mounting wing (15) and the rear mounting wing (16) of the first axle head (8) and being fixed to said first axle arm (2), and the second arm (20) extending along the rear mounting wing (16) and being fixed to said rear mounting wing (16).
