Tractor Engine Compartment Layout for Battery Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tractor designs position the reducing-agent tank above the battery, making maintenance work on the battery cumbersome due to the need to remove the reducing-agent tank, which increases the vehicle-body front-back-direction length of the engine compartment.
Innovation Solution
The reducing-agent tank and battery are positioned side by side on the vehicle-body front side of the radiator in the engine compartment, with the reducing-agent pump also placed in a side-by-side configuration, allowing for shorter space requirements and facilitating maintenance work while maintaining the reducing-agent tank and pump's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reducing-agent tank is positioned above the battery, then the engine compartment length is extended, but maintenance work on the battery becomes cumbersome requiring removal of the reducing-agent tank
Solution Approach 1:
The patent transitions from a vertical stacking arrangement (front-back direction) to a horizontal side-by-side arrangement. The reducing-agent tank and battery are positioned adjacent to each other in the width direction, allowing maintenance access to the battery without removing the tank, while keeping the front-back length compact.
2Ease of operation
If the reducing-agent tank and battery are positioned side by side, then maintenance work is facilitated and engine compartment length is shortened, but space arrangement becomes more complex
Solution Approach 1:
The patent divides the engine compartment into distinct zones: the radiator zone, the battery zone, and the reducing-agent tank zone. By segmenting the space and assigning specific functions to each zone, the side-by-side arrangement is achieved without creating overall system complexity, as each component has a dedicated location with clear access paths.
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 simplifies maintenance work on both the battery and the reducing-agent tank and pump, reducing the engine compartment's length and ensuring efficient space utilization without compromising the capacity or stability of the reducing-agent tank.
Implementation Method 1
a radiator that is provided on a vehicle-body front side of an engine in an engine compartment and cools the engine
Implementation Method 2
the radiator serves as a heat-insulating wall positioned between the engine and the reducing-agent tank, the radiator suppresses heat transfer from the engine to the reducing-agent tank
