Maglev Suspension Frame Assembly With Nested Air Spring Cavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional maglev vehicle suspension frames are heavy, have a high center of gravity, and require additional components like dustproof covers due to exposed air springs, which complicates their design and operation.
Innovation Solution
The suspension frame assembly incorporates a cavity on the corbel as an air spring mounting seat, allowing the air spring to be housed within, eliminating the need for dustproof covers, transverse pull rods, and air spring corbel beams, thereby reducing weight and center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air spring is mounted above the corbel with an air spring corbel beam and dustproof cover, then the air spring is protected and can function properly, but the suspension frame becomes large in weight and high in center of gravity
Solution Approach 1:
The patent merges the air spring mounting function directly into the corbel structure by forming a mounting cavity integrally with the corbel. This eliminates the need for separate air spring corbel beams and dustproof covers, combining multiple components into one unified structure that reduces overall weight while maintaining protective and mounting functions.
Solution Approach 2:
The air spring is nested within the mounting cavity formed in the corbel structure. This nesting arrangement allows the air spring to be housed inside the corbel rather than mounted externally, reducing the center of gravity height and eliminating the need for external support beams and protective covers.
2Reliability
If the air spring is mounted above the corbel with additional components, then the air spring is protected from dust and damage, but the suspension frame requires more components and becomes more complex
Solution Approach 1:
The mounting cavity is formed integrally with the corbel as a unified structure, eliminating the need for separate air spring corbel beams and dustproof covers. This merging of functions into a single component significantly reduces the number of parts and simplifies the overall suspension frame assembly.
Solution Approach 2:
The corbel structure is designed to serve multiple functions: it provides structural support, forms the air spring mounting cavity, and inherently protects the air spring. This multi-functionality eliminates the need for dedicated protective components, reducing complexity while maintaining reliability.
3Object-affected harmful factors
If the air spring is mounted above the corbel with a dustproof cover, then the air spring is protected from dust, but the center of gravity of the suspension frame increases
Solution Approach 1:
The air spring is nested within the mounting cavity formed in the corbel, positioning it lower within the suspension frame structure. This nesting arrangement inherently protects the air spring while lowering the center of gravity, eliminating the need for elevated mounting with external dustproof covers.
Solution Approach 2:
The protective function is merged into the corbel structure itself through the formation of the mounting cavity, eliminating the need for separate dustproof covers. This integration maintains dust protection while reducing the overall height and center of gravity of the suspension assembly.
