Sensor Cap Exchange Tool for Wheel Bearing Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for replacing or repairing wheel speed sensors require the entire wheel bearing assembly to be replaced, leading to increased repair costs and time, as the sensor cap is difficult to separate from the wheel bearing assembly.
Innovation Solution
A sensor cap exchange tool device is designed to separate and mount only the sensor cap, featuring a support bolt, support bracket, mover, tool guide, collet, and installer, which allow for the easy removal and installation of the sensor cap by rotating the mover and moving the tool guide and collet in the front-rear direction, using a collet with a cup structure and an installer with an outside diameter absorption device to accommodate different cap sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire wheel bearing assembly is replaced to repair or replace the wheel speed sensor, then the sensor replacement is ensured, but the repair cost and time increase significantly
Solution Approach 1:
The invention divides the wheel bearing assembly into separable components, specifically extracting the sensor cap as an independent replaceable unit. The sensor cap is detached from the wheel bearing assembly using a specialized tool, allowing only the sensor cap to be replaced while the main wheel bearing assembly remains in service. This segmentation enables targeted repair rather than complete assembly replacement.
Solution Approach 2:
The invention extracts the sensor cap from the integrated wheel bearing assembly, making it a separately replaceable component. The extraction tool removes the sensor cap from its mounted position on the wheel bearing assembly, allowing the sensor cap to be replaced independently while the wheel bearing assembly itself is not discarded. This extraction principle directly reduces repair scope and cost.
2Reliability
If the entire wheel bearing assembly is replaced to repair the wheel speed sensor, then the sensor functionality is restored, but the repair cost increases
Solution Approach 1:
The invention segments the wheel bearing assembly to isolate the sensor cap as a separate replaceable component. By providing a tool that can detach the sensor cap from the wheel bearing assembly, the invention enables replacement of only the faulty sensor cap rather than the entire expensive wheel bearing assembly, thereby reducing repair costs while maintaining sensor functionality.
Solution Approach 2:
The invention allows the wheel bearing assembly to be recovered and retained while only the sensor cap is discarded and replaced. The specialized tool enables removal of the sensor cap from the wheel bearing assembly, so the functional wheel bearing assembly can be kept and reused, reducing the need to discard and replace the entire assembly.
3Stability of the object's composition
If the sensor cap is difficult to separate from the wheel bearing assembly, then the assembly remains intact, but the ease of repair deteriorates
Solution Approach 1:
The invention introduces a specialized tool as an intermediary device to facilitate the separation of the sensor cap from the wheel bearing assembly. The tool includes components that engage with the sensor cap and apply controlled forces to detach it from the assembly without damaging either component. This intermediary tool makes the separation process easy and controlled.
Solution Approach 2:
The invention performs preliminary actions by providing a tool that pre-prepares the separation process. The tool is designed to engage with the sensor cap before removal, aligning and positioning the separation force to efficiently detach the cap from the wheel bearing assembly. This preliminary engagement makes the repair process easier and more straightforward.
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
This solution reduces the overall repair cost and time by allowing for the separate exchange of the sensor cap within the wheel bearing assembly, minimizing the need for full wheel bearing assembly replacement.
Implementation Method 1
a mover that has a second screw thread that is engaged with the first screw thread at an outside circumference of one side and that fixes a mover nut to a rotation central portion of a front end surface and that moves in the front-rear direction about the support bracket according to a rotate location
Implementation Method 2
a tool guide that is rotatably engaged with the rear side of the mover through a bearing
