Vehicle Support Structure for Torsional Rigidity and Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle support structures lack sufficient torsional rigidity while maintaining a compact and lightweight design, which affects the stability and maneuverability of vehicles, particularly in agricultural vehicles.
Innovation Solution
A vehicle support structure featuring a self-contained support part with a circumferentially running wall between the front and rear structural sections, which can be dimensioned for different applications and includes perforations for service access, and is designed to absorb torsional loads efficiently, allowing for modular assembly and integration with various front axle assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional support structure design is used, then the construction can be compact and lightweight, but the torsional rigidity is insufficient
Solution Approach 1:
The support structure is divided into multiple structural sections (front structural section, rear structural section, and intermediate structural sections) that are connected through support parts. This segmentation allows each section to be optimized independently for strength and weight, while the overall structure achieves high torsional rigidity through the distributed framework design.
Solution Approach 2:
The support structure employs composite construction combining different materials and structural forms (structural sections, support parts with self-contained cross sections, reinforcing elements) to achieve high torsional rigidity without excessive weight. The use of hollow support parts with self-contained cross sections provides high strength-to-weight ratio.
2Strength
If the support wall is made solid and continuous, then torsional rigidity is maximized, but service access and installation become difficult
Solution Approach 1:
The support wall is designed with varying properties along its length - predominantly self-contained for high torsional rigidity, but with localized openings at specific positions to allow service access and installation activities. This local modification of the support wall structure maintains overall structural integrity while enabling necessary maintenance operations.
3Ease of manufacture
If the front structural section is designed for specific axle assemblies, then installation is simplified, but adaptability to different axle types is reduced
Solution Approach 1:
The front structural section is designed with universal receiving capabilities that can accommodate different types of front axle assemblies. The structural section provides standardized mounting interfaces and geometric features that enable multiple axle configurations, making the support structure adaptable to various vehicle applications while maintaining simplified installation procedures.

AI summary
A vehicle having a support structure includes a front structural section for receiving a front axle assembly and a rear structural section opposite the front structural section in the longitudinal direction of the vehicle. A support part is arranged between the front structural section and the rear structural section as part of the support structure. The support part has a support wall which runs in a self-contained manner in the circumferential direction transversely with respect to the longitudinal direction of the vehicle.
