Wheel Stud Installation Tool With C-Frame and Swivel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for installing and removing wheel studs from hub assemblies are difficult due to the press-fit nature, often requiring tools that apply force through the threads, which can warp or deform the flat disc portion of the hub, and lack simplicity and ease of use.
Innovation Solution
A system comprising a C-frame with a forcing screw and swivel mechanism that applies force to the end of the stud rather than the threads, using adapters for installing and removing studs without significantly altering the hub's geometry, and includes a method involving the use of a stud installing adapter and a stud removing adapter to facilitate easy and economical operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If force is applied to the stud through the threads using existing tools, then the stud can be installed or removed, but the flat disc portion of the hub may be warped or deformed
Solution Approach 1:
A hub support device is introduced as an intermediary component between the tool and the hub assembly. This support device contacts the flat disc portion of the hub to provide stabilization and prevent warping or deformation during stud installation or removal operations, while allowing the tool to apply force to the stud through its threads without damaging the hub geometry
Solution Approach 2:
The hub support device applies a counteracting force to the flat disc portion of the hub assembly that opposes and neutralizes the warping or deforming forces generated by the tool during stud installation or removal. This counterforce maintains the hub's original geometry while permitting the necessary operational forces to be applied to the stud
2Manufacturing precision
If a tool system is designed to support the hub and reduce force applied to the hub, then hub deformation is prevented, but the system complexity increases
Solution Approach 1:
The tool system is divided into functionally independent components: a stud engagement tool that applies force to the stud threads, and a separate hub support device that independently supports the flat disc portion of the hub. This segmentation allows each component to perform its specific function without adding unnecessary complexity to the overall system, as the components can be used together or separately depending on the application
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the installation and removal of wheel studs with reduced risk of hub deformation, while being simple and economical, by applying force to the stud's end rather than its threads, thus maintaining the hub's geometry and providing a straightforward, effective method for both installation and removal.
Implementation Method 1
A substantial amount or all of the force used to install or remove the wheel stud is applied to an end portion of the stud other than the stud's threads
Implementation Method 2
a swivel mounted on an end on the forcing screw

AI summary
A wheel stud installing and removing system includes a C-frame; a forcing screw configured to communicate with the C-frame to move laterally through the C-frame; a swivel mounted on an end on the forcing screw; an adapter receiver mounted on an opposite end of the C-frame from the forcing screw, and configured to receive at least one of either a stud installing adapter and a stud removing adapter. A method of moving a stud includes: inserting one of either an installing adapter or a removing adapter into an adapter receiver on a C-frame; aligning a longitudinal axis of the adapter with a longitudinal axis of the stud; aligning the longitudinal axis of the stud with a longitudinal axis of a forcing screw; and turning the forcing screw.
