Vehicle Height Adjustment Actuator Elastomer Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for adjusting the height of a motor vehicle body face challenges in easy connection to the vehicle body and effective damping of vibrations transmitted through actuators to the vehicle body.
Innovation Solution
A device featuring an actuator with a height-adjustable spring seat, a pin for connection to the vehicle body, and an elastomer support between the support plate and flange to absorb and damp vibrations, allowing secure load transfer via a screw-threaded pin system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actuator is rigidly connected to the vehicle body, then the load transfer is reliable, but vibrations are transmitted to the vehicle body
Solution Approach 1:
An elastomer support element is introduced as an intermediary between the actuator housing and the vehicle body mounting point. This elastomer element serves as a mediator that allows reliable load transfer while simultaneously damping vibrations, thus resolving the contradiction between reliability and vibration transmission.
Solution Approach 2:
The mounting system uses a composite structure combining rigid components (pin, flange, support plate) for load bearing with elastic material (elastomer support element) for vibration damping. This composite approach enables both reliable load transfer and vibration isolation to be achieved simultaneously.
2Stability of the object's composition
If the pin is rigidly fixed to the support plate, then the connection is stable, but adjustment movements cause vibrations to transfer to the vehicle body
Solution Approach 1:
The elastomer support element acts as a mediator between the rigid pin assembly and the vehicle body, absorbing vibrations generated during actuator adjustment movements while maintaining stable connection. This resolves the contradiction between connection stability and vibration transfer.
3Device complexity
If the actuator is directly mounted to the vehicle body, then the structure is simple, but vibration damping is insufficient
Solution Approach 1:
A relatively simple elastomer support element is added as an intermediary component between the actuator housing and vehicle body. This minimal addition provides effective vibration damping without significantly increasing structural complexity, resolving the contradiction between simplicity and vibration control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy connection and reliable load transfer while significantly reducing vibration transmission to the vehicle body, ensuring stable and secure operation of the height-adjustment mechanism.
Implementation Method 1
the elastomer support arranged between the support plate and the flange prevents or damps the transmission of vibrations of the actuator to the vehicle body
Implementation Method 2
The elastomer support can be created so that it can transfer the full load acting in the suspension strut into the vehicle body
