Hydraulic Shock-Linked Suspension for Cross-Axle Load Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle suspension systems face challenges in efficiently sharing wheel loads across axles, leading to increased complexity and cost, particularly when using electronics or sway bars, which do not effectively address cross-axle load sharing.
Innovation Solution
A multi-section shock-linked vehicle suspension system that uses hydraulics or gases like air or nitrogen to transfer force between shock absorbers, eliminating the need for mechanical levers and rods, allowing for space-efficient design and tunable suspension characteristics by sharing wheel loads across the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional suspension systems use electronics to balance wheel loads, then wheel load balancing is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces electronic systems with a purely mechanical hydraulic linkage system. The shock absorbers are mechanically connected through hydraulic fluid and valves, eliminating the need for electronic sensors, controllers, and actuators while achieving the same wheel load balancing function.
Solution Approach 2:
The patent uses hydraulic fluid and valves to create a mechanical linkage between shock absorbers. The hydraulic system allows force and motion to be transferred between shocks, enabling passive load sharing and balancing without electronic intervention.
2Stability of the object's composition
If sway bars are used to link suspensions, then anti-roll function is improved, but cost increases and cross-axle load sharing is not effectively provided
Solution Approach 1:
The patent merges the anti-roll function and cross-axle load sharing into a single integrated hydraulic linkage system. The same hydraulic connections that provide load sharing also provide anti-roll stability, eliminating the need for separate sway bars.
Solution Approach 2:
The hydraulic linkage system performs multiple functions simultaneously: it provides cross-axle load sharing, anti-roll stability, and shock absorption. This multi-functional approach replaces the need for separate dedicated components like sway bars.
3Force
If mechanical levers and rods are used to link shock absorbers, then force transfer is improved, but space efficiency deteriorates
Solution Approach 1:
The patent uses hydraulic fluid and hoses to transfer force between shock absorbers, replacing bulky mechanical levers and rods. The hydraulic system achieves the same force transfer function while occupying significantly less space and allowing greater design flexibility.

AI summary
A multi-section shock-linked vehicle suspension system is disclosed that transfers force from one point to another point in a system of interrelated shock absorbers. Force can be transmitted from one shock absorber to another using hydraulics or a gas such as air or nitrogen in a space-efficient form factor, without the use of levers and mechanical force transfer rods. The hydraulic or gas force can be tuned using valves to provide different suspension characteristics. The multi-section shock-linked system provides the ability to share wheel loads across the vehicle by using shock absorbers that are shared in addition to the individual shock absorber associated with each wheel.
