Tracked Vehicle Bogie Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tracked carrier vehicles have limited carrying capacity due to the limited number of support wheels, which can lead to excessive load on individual wheels and potential breakage when increased, while also needing to fit on public roads.
Innovation Solution
The design incorporates a chassis with a prime mover and track assemblies featuring multiple support wheels arranged in an in-line configuration, with bogies pivotally mounted to distribute weight evenly across multiple wheels, allowing for a larger payload capacity without exceeding structural limits and ensuring the vehicle can navigate public roads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of support wheels is increased to increase carrying capacity, then the payload capacity is improved, but the load per support wheel may exceed maximal structural limit and reduce useful life or cause breakage
Solution Approach 1:
The support wheels are divided into multiple groups, with each group carried by a separate bogie. This segmentation allows the load to be distributed across multiple wheels while maintaining manageable load per wheel through the bogie structure that supports multiple wheels collectively.
Solution Approach 2:
The invention introduces a vertical dimension to wheel arrangement by stacking wheels vertically in groups of two or more on each bogie. This vertical stacking allows additional wheels to be added without increasing the longitudinal footprint, thereby increasing carrying capacity while maintaining road compatibility.
2Quantity of substance
If the vehicle length is increased to accommodate more support wheels, then the carrying capacity is improved, but the vehicle may not be able to negotiate turns on public roads
Solution Approach 1:
The invention transitions from a longitudinal arrangement of wheels to a vertical stacking arrangement. By stacking wheels vertically on bogies, the vehicle can accommodate more wheels without increasing its longitudinal length, thus maintaining ability to navigate public roads while increasing carrying capacity.
Solution Approach 2:
The bogie structure serves multiple functions: it supports multiple wheels vertically, distributes load, and maintains compact longitudinal dimensions. This multi-functional design allows the vehicle to meet both road clearance requirements and increased carrying capacity simultaneously.
3Quantity of substance
If the vehicle height is increased to accommodate more support wheels, then the carrying capacity is improved, but the vehicle may not fit below underpasses
Solution Approach 1:
The support wheels are segmented into multiple groups carried by separate bogies, with each bogie supporting a specific number of wheels. This segmentation allows flexible configuration of wheel distribution to maximize carrying capacity while controlling overall vehicle height to fit underpasses.
Solution Approach 2:
Different bogies can support different numbers of wheels based on local load requirements and clearance constraints. This allows optimization of wheel distribution to achieve maximum carrying capacity while maintaining vehicle height within limits for navigating underpasses.

AI summary
A tracked vehicle (e.g., a tracked carrier vehicle) comprising a plurality of track assemblies for traction of the tracked vehicle. Each of the track assemblies supports a portion of a weight of the tracked vehicle when the tracked vehicle is in use. Each track assembly comprises: a first wheel and a second wheel spaced apart from one another along a longitudinal direction of the tracked vehicle; a number of support wheels arranged in an in-line configuration between the first wheel and the second wheel; and an endless track disposed around the first wheel, the second wheel, and the support wheels. The support wheels may comprise at least five (5) support wheels mounted such that, when the tracked vehicle is in use, the portion of the weight of the tracked vehicle supported by the track assembly is never applied to only one of the support wheels.
