All-Terrain Vehicle Suspension Stabilizer Bar Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
All-terrain vehicles with double-wishbone type independent suspensions face challenges in achieving lateral stability due to insufficient mounting space for lateral stabilizer bars, which affects running stability and complicates maintenance.
Innovation Solution
The vehicle design incorporates a lateral stabilizer bar mounted above the rocker arm assemblies and a front vertical beam, allowing for improved lateral stability without obstructing the steering gear, utilizing ball-pin connecting rods and a mounting device for secure and space-efficient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If double-wishbone type independent suspension is adopted to meet long working stroke requirement, then wheel working stroke is improved, but lateral stability deteriorates due to low roll stiffness
Solution Approach 1:
The suspension system is segmented into double-wishbone independent suspension for wheel stroke and lateral stabilizer bar for roll stiffness, allowing each component to specialize in its function without compromising the other
Solution Approach 2:
The lateral stabilizer bar is integrated with the double-wishbone suspension system by connecting it to the upper rocker arms, merging the functions of achieving long wheel stroke and providing lateral stability into a unified suspension system
2Stability of the object's composition
If lateral stabilizer bar is added to improve lateral stability, then lateral stability is improved, but mounting space requirement increases which cannot be accommodated in front suspension area
Solution Approach 1:
The lateral stabilizer bar is positioned in the vertical dimension above the upper rocker arms rather than occupying horizontal space, utilizing the vertical space above the suspension components to accommodate the stabilizer bar without increasing the horizontal footprint
Solution Approach 2:
The lateral stabilizer bar is nested within the existing suspension structure by positioning it above and utilizing the space created by the upper rocker arms, effectively nesting the stabilizer bar function within the existing suspension geometry
3Stability of the object's composition
If lateral stabilizer bar assembly is installed to improve lateral stability, then lateral stability is improved, but disassembly and maintenance convenience deteriorates
Solution Approach 1:
The lateral stabilizer bar is designed as a separate, independently replaceable component connected via ball-pin connecting rods, allowing it to be segmented from the main suspension assembly for easier disassembly and maintenance
Solution Approach 2:
The lateral stabilizer bar can be extracted or removed from the suspension system independently without requiring disassembly of the entire double-wishbone suspension assembly, simplifying maintenance operations
