Steering Stabilizing Actuating Unit for Compact Commercial Vehicle Axles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering stabilization systems for commercial vehicles require large space and high weight due to multiple elements, making installation and maintenance complex, and there is a need for a more compact and lightweight solution that can effectively stabilize self-steering axles without active control.
Innovation Solution
An actuation unit with a housing, first and second transmission elements, and a restoring means that uses a pressure cylinder design, allowing for pivotable transmission elements and pressure elements inside the housing, which can be supported by springs or fluid to provide restoring forces, reducing weight and space requirements while maintaining effective stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate damping and resetting components are used in the steering stabilization system, then the stabilization function is achieved, but the installation space and chassis weight increase significantly
Solution Approach 1:
The patent combines the damping element and return element into a single integrated actuating unit that is mounted directly on the tie rod. This merging of previously separate components achieves the same stabilization function while reducing overall system weight and simplifying the chassis structure.
2Reliability
If multiple separate damping and resetting components are used in the steering stabilization system, then the stabilization function is achieved, but the installation space increases significantly
Solution Approach 1:
The actuating unit integrates both the damping and return functions into a single compact assembly that mounts directly to the tie rod, eliminating the need for multiple separate components and reducing the space required in the chassis.
Solution Approach 2:
The actuating unit is designed as a compact nested structure where the piston, damping element, and return element are arranged concentrically within a housing, maximizing space efficiency while maintaining full functionality.
3Reliability
If multiple separate damping and resetting systems are used, then the stabilization function is achieved, but the assembly and maintenance effort becomes very complex
Solution Approach 1:
By integrating the damping and return functions into a single actuating unit with a unified structure, the patent simplifies both assembly and maintenance procedures compared to managing multiple separate components and their interconnections.
4Stability of the object's composition
If traditional steering stabilization systems are used, then the axle return function is achieved, but the system weight and complexity increase
Solution Approach 1:
The patent extracts the essential stabilization function from the complex traditional system and implements it through a single actuating unit mounted on the tie rod, eliminating unnecessary components while preserving the axle return capability.
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
The solution provides a compact and lightweight steering stabilization system that effectively returns the self-steering axle to a neutral position, reduces vibrations, and dampens movements, thereby enhancing safety and simplifying installation and maintenance by using a combination of spring and fluid-based restoring means within the actuation unit.
Implementation Method 1
The restoring means comprises a spring element arranged inside the housing and supported by the first and second pressure elements
Implementation Method 2
arranged inside the housing and subjected to a return force acting along a return axis by a return means
