Hollow Axle King Pin Mount via Insert Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting king pins on hollow axles are cumbersome and difficult to produce, necessitating a simpler approach for attaching a king pin mount structure without complicating the manufacturing process of hollow axles.
Innovation Solution
A hollow formed axle with a plug insert at each end, featuring aligned holes for the king pin and draw keys, allows for a straightforward and secure attachment of the king pin by inserting it through the holes and locking it with bolts, simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods are used to form hollow axles with king pin mount structures, then the king pin can be mounted on the hollow axle, but the manufacturing process becomes cumbersome and difficult to achieve in production
Solution Approach 1:
The invention divides the hollow axle into two main parts: the hollow axle body and a separate solid insert plug. The plug is inserted into the hollow axle to provide the king pin mounting structure. This segmentation allows each component to be manufactured independently using simpler processes, then assembled together, resolving the contradiction between reliable mounting and manufacturing ease.
Solution Approach 2:
The solid insert plug is nested inside the hollow axle, with the plug containing the king pin mounting structure. This nesting approach allows the complex mounting structure to be housed within the simpler hollow axle body, enabling reliable king pin attachment while keeping the overall manufacturing process straightforward through sequential insertion and assembly.
2Reliability
If a solid insert plug is added to provide king pin mounting, then the king pin can be securely mounted, but the device complexity increases
Solution Approach 1:
By separating the hollow axle body from the solid insert plug, the invention creates a modular structure where the plug serves as a dedicated king pin mounting component. This segmentation provides secure attachment while managing complexity through functional separation and independent manufacturing of each component.
Solution Approach 2:
The solid insert plug acts as an intermediary component between the hollow axle and the king pin. It provides the necessary mounting structure and attachment points while being contained within the hollow axle, thus securing the king pin without requiring direct modification of the hollow axle itself.

AI summary
A king pin is mounted in a hollow axle. An insert is force fit into each end of the hollow axle. The insert includes an aperture that aligns with an aperture in a wall of the hollow axle to provide a mount structure for the king pin. This mount structure thus provides a solid and reliable mount in a very simplified manner. The hollow axle and insert are also provided with draw key holes such that bolts may lock the king pin within the insert and the hollow axle.
