Bead Releasing Roller for Tyre Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for mounting and dismounting tires are inefficient in handling large quantities of wheels, particularly front or rear wheels of vehicles, and do not ensure quick and correct treatment of wheels of different sizes, especially when preparing racing wheels for series use.
Innovation Solution
A bead releasing and thrusting group with a rotatable bead releasing roller and adjustable tool-supporting arm, capable of moving between resting and working positions, is designed to quickly and correctly treat wheels of various sizes by adjusting the advancing stroke and placement of the tool relative to the rim, allowing for efficient dismounting and mounting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed bead releasing roller and tool-supporting arm configuration is used, then the machine structure is simple, but it cannot quickly adapt to wheels of different sizes
Solution Approach 1:
The tool-supporting arm is made movable relative to the supporting column, allowing dynamic adjustment of the tool position. The bead releasing roller can be repositioned along the arm, and the arm itself can be adjusted in angle and distance from the rim, enabling the machine to adapt to different wheel sizes without requiring complete reconfiguration
Solution Approach 2:
The machine is divided into separable components: a supporting column, a movable tool-supporting arm, and a bead releasing roller. These segmented parts can be independently adjusted and repositioned, allowing quick adaptation to different wheel dimensions while maintaining overall structural simplicity
2Productivity
If the tool position is fixed relative to the rim, then the machine operation is simple, but it cannot efficiently treat large quantities of wheels with varying sizes
Solution Approach 1:
The tool-supporting arm incorporates movable elements that allow quick repositioning between different wheel configurations. The bead releasing roller can be rapidly adjusted to new positions on the arm, enabling efficient treatment of multiple wheels with varying sizes without complex operational procedures
Solution Approach 2:
The machine allows pre-adjustment of the tool position and angle on the tool-supporting arm before treating each wheel. This preliminary positioning ensures that the correct configuration is established in advance, improving treatment efficiency while maintaining operational simplicity through standardized adjustment procedures
3Manufacturing precision
If the advancing stroke of the tool is not adjustable, then the machine structure is simpler, but it cannot correctly treat wheels of different sizes
Solution Approach 1:
The tool-supporting arm includes an adjustable mechanism that allows precise control of the advancing stroke distance from the rim. This dynamic adjustment capability ensures correct treatment of wheels with different dimensions while using a relatively simple mechanical adjustment system rather than complex automated positioning
