Agricultural Vehicle Chassis Augmentation Beam Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural vehicle chassis experience significant bending stresses due to fore-aft loads from rapid decelerations and uneven terrain, particularly between the front and rear axles, which can lead to structural integrity issues.
Innovation Solution
A chassis augmentation assembly featuring vertically spaced structural beam segments that transfer longitudinal forces between chassis mounts, providing additional rigidity and resisting bending moments through compressive and tensile forces, with adjustable length mechanisms to optimize load transfer and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a heavy-duty chassis is used to support large loads and operate on rugged terrain, then the vehicle can handle heavy loads and rough terrain, but the chassis still experiences significant bending stresses that compromise structural integrity
Solution Approach 1:
The chassis is divided into multiple load-bearing components: the main frame and additional longitudinal beams. These segments work together to distribute and reduce bending stresses on individual components, preventing structural failure while maintaining heavy-load capacity.
Solution Approach 2:
The invention adds a vertical dimension to load transfer by positioning beams above or below the main frame. This creates a three-dimensional structural system that resists bending moments more effectively than a two-dimensional frame alone, reducing stress on critical chassis sections.
2Ease of manufacture
If the chassis is designed with simple construction for ease of manufacture, then manufacturing is easier and cheaper, but the chassis cannot adequately resist bending stresses from fore-aft loads
Solution Approach 1:
The chassis structure is segmented into modular components (main frame, longitudinal beams, cross members) that can be manufactured separately using standard fabrication processes and then assembled. This maintains manufacturing simplicity while achieving the required bending stress resistance through the combined structural system.
Solution Approach 2:
The invention merges the main frame with additional longitudinal beams to create a composite structural system. This combination provides enhanced bending stress resistance while using conventional manufacturing techniques for each component, avoiding the need for complex monolithic construction.
3Reliability
If additional structural components are added to reduce bending stresses, then chassis structural integrity is enhanced, but the device complexity and weight increase
Solution Approach 1:
The longitudinal beams serve multiple functions: they resist bending moments, provide mounting points for equipment, and work with the main frame to distribute loads. This multi-functionality reduces the need for separate components and justifies the added structural elements by providing multiple benefits from each added element.
Solution Approach 2:
By adding structural elements in the vertical dimension (above or below the main frame), the invention creates a three-dimensional load path that more efficiently resists bending stresses. This approach provides enhanced structural integrity without significantly increasing lateral complexity, as the additional components are positioned vertically rather than adding to the overall footprint.

AI summary
A chassis augmentation assembly for, and an agricultural vehicle with, a chassis having a main frame supporting front and rear axles has longitudinally spaced chassis mounts attached to the vehicle and a beam assembly having at least one structural beam segment vertically spaced from the main frame. The beam assembly has longitudinally spaced ends coupled to the vehicle chassis via the chassis mounts. The beam assembly is configured to transfer longitudinal forces between the chassis mounts through the one or more structural beam segments.
