Tractor Steering Wheel Hub Loader Lever Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing operating systems for tractor front loaders are cumbersome and complex, making it difficult for operators to easily manage the loader operation lever while steering the tractor, which compromises operator comfort and space.
Innovation Solution
A streamlined operating system for tractors with a steering wheel, control panel, center cover, and a link mechanism that positions the operation lever laterally adjacent to the control panel, with a valve unit covered by the center cover, allowing for easier operation and reduced structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the loader operation lever is positioned at a high position next to the steering wheel to facilitate operation during steering, then the ease of operation is improved, but the device complexity increases due to the need for specialized frames and multiple structural components
Solution Approach 1:
The patent merges the loader operation lever with the existing steering wheel assembly, positioning the lever on the steering wheel hub itself. This integration eliminates the need for separate support frames and additional structural components, thereby maintaining ease of operation during steering while significantly reducing device complexity
Solution Approach 2:
The steering wheel assembly is given multiple functions: it serves both as the primary steering control and as the mounting structure for the loader operation lever. This multi-functionality eliminates the need for dedicated loader operation structures, reducing overall device complexity while preserving operational ease
2Ease of operation
If specialized frames are provided to support the operation lever at a high position, then the ease of operation is improved, but the quantity of structural components increases
Solution Approach 1:
The operation lever is merged with the steering wheel hub, eliminating the need for separate support frames. This integration reduces the quantity of structural components while maintaining the high-position advantage for easy operation during steering
Solution Approach 2:
The patent extracts the operation lever from the traditional separate mounting arrangement and repositions it directly on the steering wheel hub, removing the intermediary support structures and reducing the total quantity of structural components required

AI summary
An operating system for a tractor to which an implement is attachable, the operating system comprises: a steering wheel provided rearwardly of a hood that houses an engine located in a forward region of the tractor; a control panel provided rearwardly of the hood and adjacent the steering wheel; a center cover extending generally vertically below the steering wheel; an operation lever provided at a position laterally of the control panel; a valve unit with a pair of spools, the valve unit being located at a lower position with respect to the steering wheel and being covered by the center cover; a link mechanism that links the operation lever and the pair of spools, the link mechanism being covered by the center cover.
