Air Spring Fastening Positioning Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in precisely positioning and fixing different air springs to a shared trailing arm unit or vehicle frame of commercial vehicles, leading to increased manufacturing costs due to the need for customized designs.
Innovation Solution
An air spring attachment system featuring a positioning element with engagement sections and a guide link unit, allowing for adjustable positioning and secure fastening of the air spring relative to the trailing arm unit and frame, using a combination of engagement and fastening sections to accommodate various air spring sizes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different air springs are to be used on a frame with a specific geometric configuration, then the air spring can be precisely positioned on the frame and guide arm assembly, but the guide arm assembly and the interface on the frame must each be specifically designed, which significantly increases the manufacturing effort
Solution Approach 1:
The guide arm assembly is designed with a universal mounting system that can accommodate different air spring types and sizes through adjustable positioning elements and multiple engagement sections, eliminating the need for custom-designed assemblies for each air spring variant
Solution Approach 2:
The mounting system incorporates adjustable and reconfigurable components that can be dynamically positioned and secured in multiple configurations, allowing the same guide arm assembly to adapt to different air spring geometries without requiring redesign
2Adaptability or versatility
If different air springs are to be used on one and the same commercial vehicle, then the guide arm assembly and the interface on the frame must each be specifically designed, but this significantly increases the manufacturing effort
Solution Approach 1:
A universal mounting interface is provided on the frame that can accommodate multiple air spring types through a standardized connection system with adjustable positioning elements, allowing one design to serve multiple functions across different vehicle configurations
Solution Approach 2:
The mounting system is divided into modular components including a positioning element with separate engagement sections, allowing independent adjustment and configuration to match different air spring requirements without redesigning the entire assembly
