Vehicle Suspension Mount Damper Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle suspension systems often fail to effectively distribute and dampen loads across the suspension components, leading to noise, vibration, and harshness, particularly in lateral movements, which affects ride quality and vehicle handling.
Innovation Solution
A suspension system that includes a mounting member coupled to an axle via dampened coupling members and a track bar connected to the vehicle body, utilizing mount and track dampers to absorb and distribute loads, allowing for tuned stiffness to improve stability and reduce noise and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional suspension systems use rigid coupling members to connect mounting member to axle, then structural strength is improved, but noise and vibration increase due to ineffective load dampening
Solution Approach 1:
The patent introduces dampers as intermediary elements between rigid coupling members to connect the mounting member to the axle. These dampers serve as mediators that transmit necessary structural forces while filtering out harmful vibrations and noise, thus maintaining strength while reducing harmful factors.
Solution Approach 2:
The coupling members are constructed as composite structures combining rigid elements (for strength) and dampening elements (for vibration control). This composite approach allows the system to simultaneously achieve high structural strength and effective noise/vibration reduction.
2Device complexity
If conventional suspension systems use simple track bar connection, then device complexity is reduced, but lateral movement control and ride quality deteriorate
Solution Approach 1:
The track bar connection is segmented into multiple functional components: rigid coupling members for structural connection and integrated dampers for vibration control. This segmentation allows each component to perform its specific function optimally while working together to provide both simplicity and stability.
3Object-generated harmful factors
If mount dampers are added to coupling members, then noise and vibration are reduced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The damper components are merged with the rigid coupling members to form integrated assembly units. This merging eliminates the need for separate mounting hardware and complex assembly procedures, reducing overall device complexity despite adding dampening functionality.
Solution Approach 2:
The coupling members are designed as multi-functional components that simultaneously provide structural connection, load transmission, and vibration dampening. This universality reduces the total number of components needed and simplifies the overall system architecture.
