Spring Strut Mount Detent Mechanism Prevents Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring strut support mounts face the risk of loosening during operation due to reliance on preload for security against screw connection loosening, which can lead to instability in vibration damping and force transmission.
Innovation Solution
Incorporation of a two-part detent device with lugs and grooves on the housing members, where the lugs engage with grooves having a one-sided slope, allowing forward rotation but preventing backward rotation, ensuring the threaded connection remains secure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damping element is fixedly clamped between housing members using a threaded connection with preload, then good force transmission and vibration damping are ensured, but the screw connection can loosen during operation
Solution Approach 1:
The detent device features asymmetric grooves with slopes in only one direction, allowing the lug to engage easily in the forward direction while preventing backward movement. This asymmetric geometry provides inherent security against loosening without requiring additional complex locking mechanisms
Solution Approach 2:
The detent device acts as an intermediary element between the first and second housing members, providing a mechanical interlock that supplements the threaded connection. The lug and groove interaction serves as a mediator that prevents loosening while maintaining the simplicity of the overall assembly
2Reliability
If the damping element is preloaded in the housing, then good vibration damping is ensured, but the threaded connection of housing members can loosen
Solution Approach 1:
The detent device provides preliminary anti-action by preventing the loosening direction before it can occur. The asymmetric groove geometry creates a mechanical barrier that opposes any loosening tendency, allowing the preload to be applied without risk of subsequent loosening
3Reliability
If a detent device with asymmetric grooves is used, then security against loosening is greatly increased, but the device complexity increases
Solution Approach 1:
The detent device is merged with the housing members themselves, with the lug formed on one housing member and the grooves formed on the other housing member. This integration eliminates the need for separate detent components, reducing overall device complexity while maintaining high security against loosening
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
The detent device allows for precise preload of the damping element without risking loosening, providing a high degree of security against unintended opening or loosening of the threaded connection, thus enhancing durability and vibration damping.
Implementation Method 1
the elasticity of the materials permits a corresponding elastic deformation of the detent device

AI summary
The invention is directed to a spring strut support mount, including a damper element and a mount housing having a first and a second housing member, wherein the housing members can be threadably engaged by a thread so as to encompass the damping element. The housing members have a detent arrangement which permits a screwing action but prevents a loosening of the thread connection. The invention provides for improving a spring strut support mount such that the housing members cannot loosen from one another during operation. The housing members have a detent arrangement which permits a screwing action but prevents a loosening of the thread connection.
