Tractor Engine Controller Vibration Isolation and Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tractor designs face challenges in maintaining the engine controller due to its placement behind the engine, making access difficult, and are prone to vibrations and heat transfer, leading to potential operational abnormalities.
Innovation Solution
The tractor is configured with an engine controller supported by a vibration-isolating rubber member, positioned above a support plate, and separated from the engine body by a partition plate, with the engine harnesses routed through a ribbed intake pipe to reduce components and enhance maintenance accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the engine controller is disposed behind the engine body, then the controller is integrated with the engine structure, but the maintenance accessibility deteriorates
Solution Approach 1:
The engine controller is relocated from a horizontal arrangement (behind the engine) to a vertical arrangement (above the engine on a support member), changing the spatial dimension of placement. This dimensional shift maintains integration within the engine bay while providing superior access from above for maintenance operations.
2Device complexity
If the engine controller is disposed behind the engine body, then the engine bay layout is simplified, but the vibration isolation capability deteriorates
Solution Approach 1:
A support member with vibration-isolating rubber members is introduced as an intermediary between the engine controller and the engine bay structure. This intermediary component absorbs vibrations and impacts, protecting the engine controller while maintaining a relatively simple overall layout.
3Length of moving object
If the engine controller is disposed close to the engine body, then the wiring length is reduced, but the heat transfer to controller increases
Solution Approach 1:
The engine controller is extracted from the immediate vicinity of the engine body and mounted on a support member positioned above it. This separation creates thermal distance that reduces heat transfer to the controller while the wiring remains relatively short by routing along the support structure.
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 configuration reduces vibrations and heat transfer to the engine controller, facilitating easier maintenance and stable operation by isolating the controller from engine vibrations and heat, while also optimizing space usage and reducing manufacturing costs.
Implementation Method 1
The engine controller is supported by the second support member with the vibration-isolating rubber member interposed therebetween
Implementation Method 2
The vibration-isolating rubber member includes a plurality of vibration-isolating rubber members
