Solution Overview
Problem
Existing assembly arrangements for components on vehicle frames have limitations in achieving optimal damping and aging characteristics while maintaining the same space and material requirements, with conventional disk spring designs often resulting in inadequate damping and faster aging.
Innovation Solution
An assembly arrangement featuring an abutment portion at the component end and an abutment portion at the environment end, with a damping portion that approximates a periodic function, such as a wave spring design, where bearing surfaces are formed at the maximum amplitudes, allowing for improved damping and aging characteristics without increasing space or material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional disk spring designs are used, then the structure is simple and space requirements are met, but damping characteristics are inadequate and aging occurs faster
Solution Approach 1:
The damping portion is designed with a wave spring-like periodic shape featuring multiple amplitudes and bearing surfaces, transforming the conventional flat disk spring into a curved, three-dimensional structure. This curvature increases the working region and improves damping characteristics while maintaining compact dimensions suitable for vehicle frame applications
2Reliability
If the working region is increased to improve damping characteristics, then vibration absorption improves, but the space requirements and material usage increase
Solution Approach 1:
The damping portion utilizes the third dimension by creating a wave spring-like structure with periodic amplitudes extending axially. This vertical dimensionality allows the working region to be increased without expanding the radial or circumferential footprint, maintaining compact overall dimensions while achieving superior damping performance
3Force
If bearing surfaces are formed at maximum amplitudes of the periodic function, then axial spring rate increases, but manufacturing precision requirements increase
Solution Approach 1:
The periodic function parameters (amplitude, wavelength, number of cycles) are optimized to achieve the desired axial spring rate. By carefully selecting these parameters, the bearing surfaces at maximum amplitudes provide increased force capability while the continuous periodic shape allows for robust manufacturing tolerances
