Vehicle Traction Assembly Pivot Point Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traction kits for vehicles, such as snowmobiles and ATVs, face issues with weight distribution and maneuverability when replacing wheels, leading to uncomfortable rides due to large pivot movements around the axle axis, and often require additional weighty components to prevent contact with the vehicle body.
Innovation Solution
A traction assembly featuring an endless traction band with a sprocket wheel, idler wheels, and a support structure with pivot points, allowing for adjustable weight distribution and reduced pivot amplitude, which can be easily retrofitted to vehicles and installed on either side, incorporating a shock absorber for improved riding quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the traction kit pivots around the axle axis to follow terrain bumps and depressions, then the traction assembly can adapt to uneven ground, but the large pivot movements cause uncomfortable rides and require additional weighty components to prevent contact with the vehicle body
Solution Approach 1:
The patent relocates the pivot point from the axle axis to a lower position beneath the axle, changing the dimensional reference point for rotation. This dimensional shift reduces the arc of movement and prevents excessive lateral displacement that causes discomfort and potential contact with the vehicle body, while still allowing the traction assembly to follow terrain variations
2Adaptability or versatility
If the traction kit pivots around the axle axis, then the assembly can follow terrain variations, but unnecessary large movements are translated into uncomfortable ride for the user
Solution Approach 1:
By moving the pivot point to a lower dimension (beneath the axle rather than at the axle level), the patent reduces the radius of rotation. This allows the traction assembly to still follow terrain bumps and depressions but with smaller angular displacements, thereby reducing the magnitude of movements transmitted to the vehicle and improving rider comfort
3Reliability
If means are added to prevent contact between the traction assembly and the body of the vehicle, then contact interference is prevented, but the weight and cost of the assembly increase
Solution Approach 1:
Relocating the pivot point beneath the axle changes the spatial trajectory of the traction assembly during rotation. This dimensional repositioning naturally reduces the likelihood of contact with the vehicle body, eliminating or reducing the need for additional protective components that would add weight and cost
