Vehicle Chassis Wheel-Guiding Link Buckling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel-guiding links in vehicle chassis are not adequately designed to withstand extreme overload without transferring excessive forces to other components, potentially causing damage when they buckle, and existing modular systems do not effectively manage varying critical overloads across different vehicle models.
Innovation Solution
A wheel-guiding link with a rod-shaped section in the form of an open metallic hollow profile reinforced with plastic profile parts, featuring a buckling load-reducing formation on its wall sections, which are designed to buckle under pressure overload, thereby preventing damage to other components by controlling the buckling load to be lower than adjacent areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wheel-guiding link is designed with high strength to withstand extreme overload, then the link can resist higher compressive forces, but excessive forces are transferred to other components causing damage
Solution Approach 1:
The wheel-guiding link is divided into segments with different wall thicknesses: a first wall section with standard thickness and a second wall section with reduced thickness. This segmentation allows the link to have high overall strength while creating a specific薄弱 section that buckles first under extreme overload, preventing force transfer to other components.
Solution Approach 2:
The link exhibits non-uniform local quality through varying wall thicknesses in different sections. The second wall section has deliberately reduced thickness to create a lower buckling load zone, while the first wall section maintains standard thickness for normal load bearing. This local differentiation enables controlled buckling behavior that protects the overall system.
2Ease of manufacture
If the wheel-guiding link is designed with uniform wall thickness for consistent strength, then manufacturing is simplified, but the link cannot be adapted to different critical overload requirements across vehicle models
Solution Approach 1:
The invention changes the geometric parameter of wall thickness along the length of the rod-shaped section. By varying this parameter to create different wall thickness zones, the buckling load can be precisely controlled to match different critical overload requirements for different vehicle models, while still using extrusion manufacturing processes.
Solution Approach 2:
The wheel-guiding link design serves multiple functions: it bears normal operational loads through its first wall section, provides controlled buckling protection through the second wall section, and can be adapted to different vehicle models by adjusting the dimensions and positioning of the weakened section, all within a single extruded component.
3Object-affected harmful factors
If the wall thickness is reduced to lower the buckling load for protection, then other components are protected from damage, but the overall strength and stiffness of the link decreases
Solution Approach 1:
The link is segmented into a first wall section with standard thickness for maintaining overall strength and a second wall section with reduced thickness for controlled buckling. This segmentation allows the majority of the link structure to retain full strength while a localized section provides protection through sacrificial buckling.
Solution Approach 2:
The reduced wall thickness is applied locally only in the second wall section where buckling is desired, while the first wall section maintains standard thickness. This localized quality change ensures that the overall link strength is preserved while providing targeted protection through controlled weakness in specific areas.

AI summary
The invention relates to a wheel-guiding link of a vehicle chassis, comprising at least one rod-shaped section which is produced in the shape of an open hollow profile (1) in a metallic substance, said open hollow profile (1) being reinforced by at least one plastic profile part (3, 3a, 3b) supported on wall sections thereof, wherein such wall sections have a shape (1c, 1d) which reduces buckling load. The reinforcing plastic profile part (3, 3a, 3b) can rest against the wall sections on the inside and/or the outside, be approximately a rectangular cuboid, and comprise integrated slots. In this way, a building block can be formed, for different buckling loads of designed links, having comparable wheel guide geometry, the same hollow link profile and different plastic profile parts.
