Multi-point Arm Assembly Roll Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicles with high centers of gravity, such as tankers and meat transport vehicles, experience insufficient roll stabilization, leading to increased rolling movements during cornering, which affects the driving experience due to inadequate rear axle stabilization.
Innovation Solution
A multipoint link arrangement with a support bracket connected to the vehicle frame at a defined support height, absorbing rolling forces through node elements and a cross member, allowing for flexible pre-assembly modules and variable frame tracks, effectively supporting roll-stabilizing forces in a compact and reliable manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stabilizer is added to the lower link level in addition to the four-point link, then roll stabilization is improved, but structural complexity increases
Solution Approach 1:
The stabilizer is integrated with the existing four-point link structure by connecting it to the link arms at defined support heights. This merging approach allows the stabilizer to be incorporated into the existing suspension system without requiring completely separate mounting structures, thereby improving roll stabilization while minimizing the increase in structural complexity.
2Adaptability or versatility
If support brackets are designed for different vehicle types with variable frame tracks, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The support bracket design incorporates adjustable parameters such as support height and mounting positions that can be varied to accommodate different vehicle types and frame tracks. By designing the bracket with adjustable features rather than completely different designs for each vehicle type, the system achieves high adaptability while maintaining relatively simple manufacturing processes.

AI summary
The arrangement (6) has a multi-point steering (7) i.e. X-steering, indirectly connected with a vehicle frame (1) at different steering connection points by a support console. The console is connected at a support height at the frame with respect tot a vehicle vertical axis direction in a region of the connection points, where the height amounts between 90 to 250 millimeters. The console receives forces i.e. rolling forces, of a defined force spectrum, where the forces are induced by the steering. Right steering arms (8, 9) are connected to the connection points by elastomer bearings.
