Dump Body Guide Portions Centering Pivot Axle Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dump vehicles experience high wear and maintenance needs on the pivot axis due to the design of the dump body, which is not optimized for reduced complexity and efficient load distribution during pivotal movements.
Innovation Solution
An autonomously electrically driven working machine with a dump body featuring a load receiving area and a pivotably attached load dumping end portion, supported by guiding plates and guide portions that are inclined to center the dump body during pivotal movements, distributing the load and reducing torque on the pivot axle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dump body is pivotably attached to the working machine frame through a pivot axis, then the dump body can perform pivotal movements for loading and unloading, but the pivot axis experiences high wear and requires frequent maintenance
Solution Approach 1:
The dump body is divided into two end portions (first end portion with attachment means and second end portion with load supporting means), with the load transfer path segmented through separate guiding plates and guide portions. This segmentation distributes the mechanical stress away from the pivot axis, reducing wear while maintaining pivotal movement capability.
Solution Approach 2:
Guiding plates and guide portions are introduced as intermediary elements between the dump body and working machine frame. These intermediaries transfer the load through their inclined surfaces during pivotal movement, preventing direct load transmission through the pivot axis and thereby reducing wear on the pivot joint.
2Device complexity
If the dump body design is simplified to reduce complexity, then manufacturing and maintenance become easier, but the load distribution during pivotal movements may be insufficient
Solution Approach 1:
The guiding plates and guide portions are designed with specific inclination angles optimized for efficient load transfer during pivotal movements. By carefully selecting these geometric parameters, the design achieves effective load distribution without requiring complex mechanical structures, thus maintaining simplicity while ensuring proper force distribution.
3Force
If the guiding plates and guide portions are inclined to center the dump body during pivotal movement, then the load is distributed effectively, but the design complexity increases
Solution Approach 1:
The inclined guiding plates and guide portions create a load path that naturally centers the dump body during pivotal movement, similar to how inclined planes distribute weight. This geometric solution achieves load distribution and centering functions through simple inclined surfaces rather than complex active control mechanisms, maintaining design simplicity while ensuring effective force distribution.
