Integrated Stabilization Device for Vehicle Axles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilization devices for vehicle axles require large installation space and high production costs due to numerous individual assemblies, and they separate steering stabilization and reversing lock functions into distinct systems.
Innovation Solution
A stabilization device comprising a hollow cylinder unit with a fluid and a piston unit that can displace between original and deflected positions, a pretensioning device to restore the wheels to the original position, and a control device to regulate fluid flow, allowing the device to function as both a steering stabilization system and a reversing lock with reduced space and cost requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pneumatic or mechanical reversing locks are additionally installed, then the wheels can be fixed in their original position for backward movement, but the number of individual assemblies increases leading to large installation space and high production costs
Solution Approach 1:
The patent combines the steering stabilization function and the reversing lock function into a single integrated stabilization device. The hollow cylinder unit with piston unit serves dual purposes: providing steering stabilization during normal operation and acting as a reversing lock when the vehicle moves backward, eliminating the need for separate reversing lock assemblies
Solution Approach 2:
The stabilization device is designed to perform multiple functions: steering stabilization during forward movement and automatic reversing lock during backward movement. The control device automatically switches between these functions based on the vehicle's movement direction, making the system universal and eliminating the need for separate specialized components
2Reliability
If pneumatic or mechanical reversing locks are additionally installed, then the wheels can be fixed in their original position, but the installation space requirement increases
Solution Approach 1:
The patent merges the reversing lock function into the existing stabilization device structure. The hollow cylinder unit and piston unit that provide steering stabilization also serve as the reversing lock mechanism, eliminating the need for additional space-consuming separate reversing lock assemblies
3Reliability
If pneumatic or mechanical reversing locks are additionally installed, then the wheels can be fixed in their original position, but the production costs increase
Solution Approach 1:
The patent combines two separate functions (steering stabilization and reversing lock) into a single device, reducing the total number of components that need to be manufactured, assembled, and quality-checked. This integration reduces production complexity and costs while maintaining both functions
Solution Approach 2:
By designing the stabilization device to perform multiple functions, the patent eliminates the need to manufacture and install separate reversing lock components, thereby reducing production costs through component consolidation and reduced assembly operations
