Vehicle Attachment Stabilizer Locking to Prevent Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle attachment stabilizers experience increased wear due to the relative movement between the spring bracket and the locking collar, which can lead to unintentional length adjustments.
Innovation Solution
A stabilizer design featuring a locking device connected to both the second adjusting element and the second connecting element, ensuring a rotationally fixed connection in the locking position, thereby preventing wear and unintentional length changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring bracket is used to prevent unintentional rotation of the second adjusting element, then the stabilizer maintains its length, but the relative movement between the spring bracket and locking collar causes increased wear
Solution Approach 1:
A locking lever is introduced as an intermediary component between the spring bracket and the locking collar. The locking lever pivots on the adjusting element and engages with the spring bracket, while the locking collar engages with a corresponding feature on the locking lever. This intermediary mechanism allows the spring bracket to maintain engagement without direct relative movement against the locking collar, thereby reducing wear while preserving the prevention of unintentional rotation.
2Adaptability or versatility
If the second connecting element is rotatable relative to the second adjusting element via screw connection, then the stabilizer length can be adjusted, but the connection is susceptible to wear and unintentional changes
Solution Approach 1:
The locking device (locking lever and locking collar) is engaged in advance to prevent unwanted rotation of the second adjusting element relative to the second connecting element. By establishing this preliminary constraint, the system prevents unintentional length changes that would otherwise occur due to wear or accidental movement of the screw connection, while still allowing intentional adjustment when needed.

AI summary
A stabilizer for an attachment device of a vehicle comprises a first adjusting element and a second adjusting element which are guided adjustably relative to one another along a longitudinal axis in order to vary the length of the stabilizer, a first connecting element on the first adjusting element for supporting the stabilizer against the vehicle, and a second connecting element on the second adjusting element for supporting the stabilizer against an element of the attachment device, the second connecting element being connected to the second adjusting element such that it can be rotated about the longitudinal axis via a screw connection for adjusting the length of the second adjusting element. The stabilizer further has a locking device, which is connected to the second adjusting element and the second connecting element, the second adjusting element and the second connecting element being connected to one another in a rotationally fixed manner in a locking position of the locking device.
