Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent manufacturing and replacement of suspension systems and test fixtures for chassis parts like wheels and steering knuckles in vehicle testing increase development costs and resource consumption, necessitating a more efficient and cost-effective simulation road test solution.
Innovation Solution
A universal suspension system comprising a backboard, simulated shock absorption tower, dashpot, steering link, and lower control arm with adjustable components made from specific steels, allowing for customizable assembly and replacement of original vehicle suspension systems, compatible with most Macpherson suspensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different products are used to make different test fixtures and suspension systems for testing durability of chassis parts, then the durability of parts can be verified, but frequent manufacturing and replacement of suspension systems increases product development cost and consumes lots of human and material resources
Solution Approach 1:
The patent creates a universal suspension system with standardized mounting interfaces that can accommodate multiple different chassis parts (wheels, steering knuckles, etc.) from different manufacturers. The backboard features multiple elongated holes and bolt holes arranged in specific patterns, allowing the same suspension system to be used for testing various products without requiring custom fixtures for each part, thereby resolving the contradiction between reliability verification and device complexity
2Reliability
If different products are used to make different test fixtures and suspension systems for testing durability of chassis parts, then the durability of parts can be verified, but frequent manufacturing and replacement of suspension systems increases product development cost
Solution Approach 1:
The universal suspension system with standardized mounting interfaces allows a single test fixture to verify durability of multiple different chassis parts, eliminating the need to manufacture separate suspension systems for each product. This significantly reduces product development costs while maintaining the ability to perform reliable durability verification across different manufacturers' parts
3Reliability
If different products are used to make different test fixtures and suspension systems for testing durability of chassis parts, then the durability of parts can be verified, but frequent replacement of suspension systems consumes lots of human and material resources
Solution Approach 1:
The patent designs a universal suspension system that can test multiple different chassis parts using the same physical infrastructure. This eliminates the need to frequently manufacture and replace suspension systems for different products, thereby conserving human resources (less manual assembly/disassembly) and material resources (reduced steel, fasteners, and other materials consumed in frequent manufacturing cycles)

AI summary
The present disclosure belongs to the technical field of tests of wheels and automobile chassis suspension systems, and provides a universal suspension and test equipment for an automobile chassis simulation road test. A simulated dashpot is movably connected to a simulated shock absorption tower; a simulated steering link and a simulated lower control arm are both movably connected to a backboard; and the simulated dashpot, the simulated steering link, and the simulated lower control arm are all assembled with corresponding mounting holes in a steering knuckle. Simulated parts with adjustable lengths and positions are used to replace an original vehicle's dashpot, steering link and lower control arm of a suspension, so that by means of adjusting lengths and angles of all the parts of the test suspension, the universal suspension can be applicable to the spatial hard point requirements of most current Macpherson suspensions.
