AI Technical Summary

Technical Problem

Existing wheel suspensions for commercial vehicles are heavy, complex, and expensive due to their compact design and numerous welds, limiting space for additional storage and requiring high manufacturing complexity.

Method used

A hollow, symmetrical stub element with a support area that is plane-symmetric or rotationally symmetric about a stub axis, allowing for a compact design with high area moments of inertia, reducing weight and simplifying manufacturing through material bonding and friction welding.

Benefits of technology

The solution provides a lightweight, compact axle system with enhanced force transmission capabilities, increasing cargo space and reducing manufacturing complexity while maintaining durability and efficiency.

Abstract

Stub element (6) for use in an axle system, wherein the stub element (6) has a support area (62), wherein the stub element (6) is essentially symmetrical about two planes which intersect in a stub axis (S), wherein the stub element (6) is hollow at least in the area of ​​the support area (62), wherein the support area (62) has a support length (L) parallel to the stub axis (S) which is smaller than the mean outer diameter (D1) of the support area (62), wherein the support length (L) is in a ratio of 0.2 to 0.6 to the total length of the stub element (6) along the stub axis (S).
