Swing Dampener Joint Assembly for Easier Brake Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Servicing of swing dampener brakes in joint elements installed in boom assemblies is difficult, requiring dismantling of the entire joint element or removal of hydraulic hoses, which complicates maintenance and increases operational risks.
Innovation Solution
A joint element design with a swing dampener brake that allows the second end part to be moved to a detached position axially, enabling servicing from outside the joint assembly without disturbing hydraulic hoses, while maintaining radial load-bearing capacity through a bearing-mounted first end part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the joint element is designed as a integrated unit, then structural strength and radial load-bearing capacity are improved, but servicing complexity increases requiring dismantling of the entire joint element
Solution Approach 1:
The joint element is divided into a first joint part and a second joint part that can be detachably connected. The second joint part can be separated from the first joint part while maintaining radial load-bearing capacity through the bearing-mounted first end part, enabling servicing of the swing dampener brake without dismantling the entire joint element.
2Ease of operation
If hydraulic hoses are removed for servicing, then access to the swing dampener brake is improved, but operational reliability decreases due to increased assembly/disassembly cycles
Solution Approach 1:
The second joint part containing the swing dampener brake is extracted from the first joint part through the detachable connection. This allows servicing of the brake components without removing hydraulic hoses or other flexible elongated elements, as the extraction only requires separating the joint parts while maintaining bearing support.
3Ease of repair
If the joint element is made fully detachable for easy servicing, then ease of repair is improved, but radial load-bearing capacity during servicing is compromised
Solution Approach 1:
The connection between the first and second joint parts is made dynamically adjustable. The second joint part can be detached for servicing while the first end part remains bearing-mounted to the first joint part, providing dynamic load-bearing capability during the servicing process rather than requiring complete disassembly.
4Difficulty of detecting and measuring
If the entire joint element is dismantled for brake servicing, then complete access is achieved, but loss of time and productivity increase
Solution Approach 1:
The joint element is segmented into separable parts where only the second joint part containing the brake components needs to be detached for servicing. This selective segmentation allows complete access to brake components without the time-consuming process of dismantling the entire joint element structure.

AI summary
A joint element provided with a swing dampener element and comprising a first joint part, a second joint part, and a swing dampener brake. The second joint part comprises a second end part which is detachably fixed to a first end part of the second joint part by a joint part coupling which is adapted to allow the second end part to be moved in an axial direction to a detached position in relation to the first end part, the detached position allowing replacement of active components of the swing dampener brake while the first end part remains bearing-mounted to the first joint part, the active components of the swing dampener brake comprising at least one first brake disc member and at least one second brake disc member.
