King Pin Removal Tool Stabilizing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing king pins from king pin assemblies are inefficient and lack effective mechanisms to prevent rotation of the drive plate relative to the axle member during the removal process.
Innovation Solution
A king pin removal tool comprising a drive plate, an anchor plate, a first drive member, a spacing system, and a stabilizing system that aligns the drive member with the king pin axis, allowing rotation of the drive member to displace the king pin while preventing rotation of the drive plate relative to the axle member, using a combination of spacing rods and stabilizer plates to secure the assembly.

Engineering Contradiction Analysis
1Productivity
If existing methods are used to remove king pins, then the removal process can be completed, but the process is inefficient and lacks effective mechanisms to prevent rotation of the drive plate relative to the axle member
Solution Approach 1:
The tool is divided into distinct functional modules: a drive plate for applying rotational force, an anchor plate for securing to the knuckle assembly, spacing rods for maintaining alignment, and stabilizer plates with bolts for preventing rotation. Each segment performs a specific function that collectively enables efficient and controlled king pin removal.
Solution Approach 2:
Before the actual king pin removal, the anchor plate is secured to the knuckle assembly and the stabilizer plates are positioned and tightened to prevent rotation. This preliminary securing action ensures that when the drive plate rotates to remove the king pin, the entire tool assembly remains stable and aligned, preventing unwanted rotation and ensuring efficient removal.
2Device complexity
If a simple removal tool is used, then the device complexity is low, but it cannot effectively prevent rotation of the drive plate relative to the axle member during operation
Solution Approach 1:
The tool employs segmentation by dividing the structure into modular components (drive plate, anchor plate, spacing rods, stabilizer plates) that can be independently positioned and secured. This modular approach maintains reasonable complexity while enabling precise control over rotation prevention through the stabilizer bolts that anchor the assembly to the knuckle.
Solution Approach 2:
Different parts of the tool have specialized local properties: the anchor plate provides secure attachment to the knuckle, the spacing rods maintain precise alignment distances, and the stabilizer plates with bolts provide rotational constraint at specific locations. This local specialization enables effective rotation prevention without requiring complex overall structure.

AI summary
A king pin removal tool for displacing a king pin comprises a drive plate defining a drive opening, an anchor plate, a first drive member, a spacing system, and a stabilizing system. The spacing system supports the drive plate and the anchor plate relative to the king pin such that the first drive member is aligned with the king pin axis. The first drive member engages the drive plate such that rotation of the first drive member relative to the drive plate displaces the first drive member through the drive opening and along the king pin axis to displace the king pin along the king pin axis relative to the axle member and the knuckle assembly. The stabilizing system supports the drive plate to prevent rotation of the drive plate relative to the axle member when the first drive member is rotated relative to the drive plate.
