Offset Drive Wheel Stud Press Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing and replacing wheel studs from a wheel assembly are complicated due to the close proximity of the disc flange and stud flange, making it difficult to efficiently remove and insert wheel studs during maintenance and repair.
Innovation Solution
A wheel stud press assembly comprising a frame assembly and a drive system with a drive rod and an anchor member that allows for the displacement of the wheel stud relative to the wheel opening, enabling efficient removal and insertion by offsetting the drive axis and engaging the anchor member with the wheel flange to facilitate the process.

If traditional methods are used to remove and replace wheel studs, then the process can be completed, but the operation is complicated and inefficient due to the close proximity of the disc flange and stud flange
Solution Approach 1:
The tool is divided into distinct functional components: a frame assembly providing structural support, a drive assembly generating linear motion, and an anchor member providing reaction force. This segmentation allows each component to perform its specific function efficiently, resolving the operational difficulty caused by the constrained space between flanges.
Solution Approach 2:
The anchor member acts as an intermediary element that engages with the wheel flange to provide a reaction surface. This intermediary component enables the transfer of force from the drive rod to the wheel stud without requiring direct operator manipulation in the constrained space, thereby improving ease of operation.
2Ease of operation
If the drive axis is offset from the main portion of the frame member, then the wheel stud can be effectively displaced out of the wheel opening, but the structural complexity of the frame member increases
Solution Approach 1:
The offset drive axis introduces a dimensional change to the force application geometry. By positioning the drive axis offset from the main portion of the frame member, the tool creates a lever arm that amplifies the displacement force on the wheel stud, enabling effective removal despite the added structural complexity.
Solution Approach 2:
The frame member is pre-configured with the offset drive axis geometry before operation. This preliminary structural arrangement ensures that when the drive rod engages the wheel stud, the offset geometry automatically provides the necessary mechanical advantage to displace the stud from the wheel opening.

AI summary
A wheel stud press assembly comprising a frame assembly comprising a frame member and a drive system comprising a drive rod. The drive system is supported by a shoulder portion of the frame member to displace the drive rod along the drive axis. The frame member is configured such that, when and anchor member is detachably attached to the frame member, the drive axis is offset from the main portion of the frame member. When the drive rod engages the wheel stud to force the wheel stud out of the wheel opening, at least a portion of the anchor member engages wheel flange adjacent to the wheel stud to allow the wheel stud to be forced out of the wheel opening, and the anchor portion is offset from the drive axis to allow the wheel stud to be displaced out of the wheel opening.
