Interconnected Damping Module for Active Roll Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle damping systems require high costs and installation space for separate active rolling stabilizers, and passive solutions are limited in their ability to actively influence roll stabilization, especially during severe acceleration situations.
Innovation Solution
A damping module with two interconnected damping circuits, each equipped with a pump device and compensating connections featuring nonreturn valves and adjustable throttle valves, allowing for independent control of damping forces and fluid flow between upper and lower chambers, enabling active stabilization without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If separate active rolling stabilizers are used, then roll stabilization is improved, but cost and installation space increase
Solution Approach 1:
The patent combines the rolling stabilizer function with the existing damping devices by interconnecting the damping circuits of two damping devices on opposite sides of the vehicle. The damping circuits are connected via connecting pieces that allow fluid communication between left and right damping chambers, enabling roll stabilization without separate stabilizer components.
Solution Approach 2:
The damping devices perform multiple functions: they provide both suspension damping (compression and extension) and roll stabilization simultaneously. The same damping circuit serves dual purposes, eliminating the need for dedicated rolling stabilizer components and reducing overall system complexity.
2Stability of the object's composition
If separate active rolling stabilizers are used, then roll stabilization is improved, but cost increases
Solution Approach 1:
The patent merges the rolling stabilizer function into the existing damping device structure by using shared damping circuits and connecting pieces. This eliminates the need for separate stabilizer components, reducing manufacturing costs while maintaining effective roll stabilization.
Solution Approach 2:
The damping devices are designed to perform both suspension damping and roll stabilization functions using the same components. This multi-functionality reduces the total number of parts required, lowering both manufacturing and installation costs.
3Device complexity
If passive damping circuits are used, then structural configuration is simplified, but active influencing capability is limited
Solution Approach 1:
The patent introduces adjustable throttle valves in the damping circuits that can be dynamically controlled to change damping characteristics. This allows the system to adapt to different driving conditions (cornering, acceleration, braking) while maintaining a relatively simple passive structural configuration.
Solution Approach 2:
The interconnection of damping circuits on opposite sides of the vehicle creates a feedback mechanism where fluid pressure changes in one damping device automatically influence the other, enabling active roll stabilization response without complex control systems.
