Overhead Stabilizer Bar Mounting for Vehicle Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs face challenges in effectively managing body roll during cornering, which affects traction and comfort, as traditional suspension tuning compromises between absorbing wheel displacement and controlling body roll, and mounting stabilizer bars can be cumbersome and interfere with other components.
Innovation Solution
A frame and suspension assembly that includes a stabilizer bar mounted over the final drive structure, allowing it to span between opposite suspension assemblies while maintaining ground clearance and ease of installation, thereby reducing body roll by resisting torsional loads without obstructing other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stabilizer bar is mounted in a conventional location, then it can effectively reduce body roll, but it interferes with other components and is difficult to install and maintain
Solution Approach 1:
The stabilizer bar is repositioned from a conventional lateral mounting location to an overhead mounting location above the final drive structure. This dimensional change in mounting position allows the stabilizer bar to span between opposite suspension assemblies without interfering with other components, while maintaining its body roll reduction function through vertical placement rather than lateral placement
2Ease of repair
If the stabilizer bar is positioned to clear other components, then ease of maintenance is improved, but the ability to resist torsional loads is reduced
Solution Approach 1:
The stabilizer bar is positioned in the vertical dimension above the final drive structure rather than in the lateral dimension near other components. This vertical positioning provides sufficient ground clearance and component clearance for easy maintenance while maintaining structural integrity and torsional load resistance through the overhead mounting configuration
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces body roll during cornering by transmitting torsional loads to the stabilizer bar, improving traction and comfort while allowing for easy access and maintenance, and does not compromise ground clearance or interfere with other vehicle systems.
Implementation Method 1
The stabilizer bar (also referred to as an anti-roll bar, or an anti-sway bar) is a relatively rigid member that is resistant to a torsional input caused by body roll
Implementation Method 2
The bearing(s) permits the stabilizer bar to rotate within the bearing(s) so that the stabilizer bar does not reduce or resist movement of the left-side and right-side suspension assemblies in the same direction

AI summary
A frame and suspension assembly for a vehicle can include a pair of frame members configured to support a load input thereto, a final drive structure connected to each of the frame members such that the final drive assembly is configured to input a load to the frame members, and a stabilizer bar mounted to each of the frame members and extending in a traverse direction of the vehicle over a top of the final drive structure.
