Segmented Trailing Arm Assembly for Commercial Vehicle Axles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing link arrangements for commercial vehicle axles are either complex to assemble due to the need to push the axle into a bore or lack stability, particularly in one-piece designs.
Innovation Solution
A multi-part trailing arm design featuring an upper and lower link element with an integrated or separate socket receptacle for the bearing bush, allowing for a simplified assembly process and enhanced stability through material connections like welding, and a recess for the vehicle axle between the elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a one-piece trailing arm design is used, then manufacturing stability is improved, but assembly complexity increases due to the need to push the axle into a bore
Solution Approach 1:
The trailing arm is divided into two separate parts: an upper link element and a lower link element. These two elements can be assembled around the axle without requiring the axle to be pushed into a bore, thereby simplifying assembly while maintaining structural stability through the connection of the two elements.
2Ease of operation
If a two-part trailing arm design is used, then assembly simplicity is improved, but structural stability may worsen without proper connection methods
Solution Approach 1:
The upper link element and lower link element are firmly connected to each other through material connections (such as welding) or form-fitting and force-fitting connections. This merging of the two separate elements creates a stable unified structure that maintains the benefits of simplified assembly while ensuring structural integrity.
3Ease of manufacture
If the socket receptacle is a separate component, then manufacturing flexibility is improved, but device complexity increases
Solution Approach 1:
The socket receptacle is integrated into one of the link elements (upper or lower), forming an integral part rather than a separate component. This integration reduces the total number of parts and simplifies the overall device structure while maintaining the flexibility to accommodate the bearing bushing.
