Sliding Frame Wear-Resistant Pad and Guide Rail Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sliding frames in trailers experience excessive wear due to friction and vibration, leading to a reduced service life as they adjust longitudinally along the trailer frame, causing uneven load distribution and frequent relative movements.
Innovation Solution
A sliding frame design featuring a side beam with a wear-resistant pad and a guide rail clip system, including a backing plate that prevents direct contact between the guide rail and the side beam, reducing friction and wear, and allowing for removable replacement of the backing plate when worn out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sliding frame is adjusted longitudinally along the trailer frame to distribute load, then the load distribution is improved, but the friction between the sliding frame and trailer frame causes excessive wear
Solution Approach 1:
A guide rail clip system with a backing plate is introduced as an intermediary component between the sliding frame and the trailer frame. The backing plate prevents direct contact between the sliding frame's side beam and the guide rail, reducing friction and wear. The guide rail clip includes a connection part fixed to the side wall and a limiting part that positions the backing plate, creating a protective interface that allows longitudinal adjustment while minimizing material loss through wear.
Solution Approach 2:
The friction characteristics between the sliding frame and trailer frame are changed by introducing the wear-resistant pad and backing plate system. This changes the interface properties from direct metal-to-metal contact to a configuration with reduced friction and wear, allowing the sliding frame to move longitudinally with minimal material loss while maintaining load distribution adaptability.
2Adaptability or versatility
If the sliding frame is designed for longitudinal adjustment to ensure proper load distribution, then the adaptability is improved, but the frequent relative movements due to vibration cause excessive wear
Solution Approach 1:
The guide rail clip with backing plate serves as a protective intermediary that absorbs and reduces the impact of vibrational movements. The backing plate prevents direct contact between the sliding frame and guide rail during vibration-induced relative movements, significantly reducing wear and extending the service life of both components while maintaining the longitudinal adjustment capability for load distribution.
Solution Approach 2:
The guide rail clip and backing plate are designed as replaceable components that can be easily replaced when worn. This allows the main sliding frame structure to be preserved for a longer period, effectively extending its service life. The clips and backing plates act as sacrificial elements that protect the more critical sliding frame components from excessive wear.
3Ease of operation
If traditional sliding frame adjustment is used, then the load distribution can be adjusted, but the friction causes wear and tear affecting service life
Solution Approach 1:
The guide rail clip system with backing plate is introduced as a protective intermediary between the sliding frame and the stationary trailer frame. This intermediary reduces the friction and wear caused by the sliding adjustment operation, allowing easy longitudinal movement for load distribution while significantly extending the service life of the stationary trailer frame components.
