Kingpin Assembly Torque Receiving Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kingpin assemblies in automotive suspension systems face challenges with torque application due to space constraints and the need for specialized tools, making it difficult to achieve adequate threading into a housing.
Innovation Solution
A kingpin assembly with a torque receiving configuration, such as a nut or hex hole, is integrated into the base, allowing for direct access and torque application from the opposite end of the housing bore, eliminating the need for additional torque transmitting tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a torque application tool with slots and studs is used to thread the base into the housing, then torque can be applied to the kingpin assembly, but the device complexity increases and space constraints are violated
Solution Approach 1:
The torque receiving configuration is integrated directly into the base structure, merging the torque application interface with the base itself. This eliminates the need for separate torque transmitting tools with slots and studs, reducing device complexity while maintaining adequate torque application capability
Solution Approach 2:
The base is designed with a torque receiving configuration that serves multiple functions: it provides torque application during installation, maintains structural integrity, and enables tool access from the opposite end of the housing bore. This multi-functional design eliminates the need for specialized torque transmitting tools
2Force
If a torque application tool with slots and studs is used to thread the base into the housing, then torque can be applied to the kingpin assembly, but the ease of operation deteriorates due to space constraints
Solution Approach 1:
Instead of applying torque from the same end where the base is inserted, the torque receiving configuration is positioned to allow tool access from the opposite end of the housing bore. This inversion of the torque application approach improves ease of operation by providing better tool accessibility and maneuverability in confined spaces
Solution Approach 2:
The torque receiving configuration is oriented to accept torque application from a different spatial dimension (opposite end of the bore), allowing tools to access the kingpin assembly from a more accessible direction and improving operational ease in space-constrained environments
3Force
If a torque application tool with slots and studs is used to thread the base into the housing, then torque can be applied to the kingpin assembly, but adequate torque is difficult to achieve
Solution Approach 1:
The torque receiving configuration is integrated directly into the base structure, creating a rigid, direct torque transmission path. This merging eliminates the intermediate torque transmitting components (slots and studs) that limited torque application, ensuring adequate and reliable torque can be applied during installation

AI summary
A kingpin assembly includes a pin that has a shaft with a spherical member extending therefrom. The kingpin includes a base that has a spherical interior surface which defines an interior area. The interior area includes an open end of the base and is bounded by a closed end of the base. The closed end of the base is opposite the open end. The spherical member is rotatingly disposed in the interior area with the shaft extending away from the open end. The closed end has a torque receiving configuration for receiving a torque applying tool thereon.
