ATV Track Assembly Slide-Rail Geometry for Traction and Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track systems for All-Terrain Vehicles (ATVs) face challenges in providing optimal traction and steering on various terrains, particularly when increasing vehicle performance through motor horsepower is not feasible or desirable.
Innovation Solution
The track assembly features a unique geometry and arrangement of mid-rollers and slide rails, which distribute forces more evenly across the track, improving traction and steering on different terrains without relying solely on increased motor horsepower.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If motor horsepower is increased to improve vehicle performance, then traction and acceleration are improved, but cost increases and the approach is not always effective for ATV track assemblies
Solution Approach 1:
The patent changes the geometric parameters of the track system, specifically the angle of the slide rails relative to the track frame. By optimizing this angle parameter, the system achieves improved traction and steering performance without increasing motor horsepower, thus avoiding the associated cost increase.
2Adaptability or versatility
If conventional track systems are used with guide rails, then the track system can be mounted on ATVs, but the mid-rollers experience high pressure and traction lug wag occurs
Solution Approach 1:
The patent applies local quality by optimizing the specific geometric relationship between the slide rails and track frame. The slide rails are positioned at a specific angle relative to the track frame, which locally improves the force distribution on the mid-rollers and reduces pressure concentration, thereby reducing traction lug wag while maintaining ATV compatibility.
3Force
If the track system transfers vehicle weight through mid-rollers, then the track system can support vehicle weight on terrain, but traction performance is reduced due to high pressure on mid-rollers
Solution Approach 1:
The patent changes the geometric parameter of the slide rail angle to optimize force distribution. This parameter change allows the track system to maintain weight support capability while distributing forces more evenly across the track, reducing mid-roller pressure and improving traction reliability on various terrains.
