Dump Truck Pivot Structure for Reduced Wear and Heavy-Load Towing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dump trucks face issues with wear and tear at the connection point between the body and the rotating shaft due to inadequate resistance, and they are inconvenient for towing when heavily loaded, especially when designed for manual operation.
Innovation Solution
A dump truck design featuring a body rotation shaft positioned above the rear wheel installation shaft, a V-shaped connecting frame, and a reversible or retractable handle system to enhance structural support and towing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotating shaft is used to connect the body to the frame, then the dump truck can achieve tipping function, but the connection point suffers from serious wear and tear after long-time use
Solution Approach 1:
A connecting plate is introduced as an intermediary component between the body and the rotating shaft. The connecting plate is fixed to the body while the rotating shaft rotates within bearings mounted on the connecting plate, which reduces wear on the connection point between the body and frame.
Solution Approach 2:
The connection structure is segmented into multiple components: the connecting plate fixed to the body, the rotating shaft with bearings, and the frame. This segmentation allows each component to perform its specific function while reducing overall wear on the connection point.
2Ease of operation
If the dump truck is designed for manual pushing, then operation is simple, but towing capability is inconvenient when heavy goods are loaded
Solution Approach 1:
The handle assembly is designed with multi-functionality: it can serve as a manual pushing handle for light operations and as a towing hook for heavy loads. The handle includes a receiving structure that can accommodate a trailer hook, allowing the same component to perform both manual and towing functions.
Solution Approach 2:
The handle assembly incorporates movable and adjustable components that allow it to adapt between different operating modes. The handle can be positioned and configured for either manual pushing or towing operations, providing dynamic adaptability to different workload requirements.
