Rough Terrain Vehicle Radiator Cooling with Mud-Blocking Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rough terrain vehicles face challenges in maintaining radiator cooling performance due to mud and debris splashing onto the radiator, which impairs its efficiency.
Innovation Solution
The vehicle design includes a front cover with a grille extending in the vehicle width direction, extension portions closing the gap between the bumper and radiator, and turning performance-improvement features like slits and wall portions to direct wind and prevent mud from reaching the radiator, while enhancing turning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the radiator is arranged in a position overlapped with front wheels to improve cooling efficiency, then cooling performance is improved, but mud splashed by front wheels attaches to the radiator front face
Solution Approach 1:
The patent introduces extension portions as an intermediary structure between the bumper and radiator. These extension portions close the gap and act as a barrier that prevents mud splashed by front wheels from reaching the radiator front face, while allowing the radiator to maintain its overlapping position with the front wheels for effective cooling
2Ease of manufacture
If a gap is formed between bumper and radiator to simplify structure, then manufacturing is easier, but mud can enter the gap and attach to radiator
Solution Approach 1:
The patent extends the front cover structure in the vehicle width direction to create extension portions. This dimensional extension closes the gap between bumper and radiator without complicating the overall structure, effectively preventing mud entry while maintaining manufacturing simplicity
3Object-affected harmful factors
If extension portions are added to close the gap between bumper and radiator, then mud protection is improved, but turning performance may be affected
Solution Approach 1:
The patent applies turning performance-improvement portions specifically at the outer sides of the extension portions, where they gradually spread outward toward the rear. This localized modification improves turning performance without compromising the mud protection function of the extension portions, as the protective function is primarily needed in the gap-closing region
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 effectively prevents mud from attaching to the radiator, maintains cooling performance, and improves the vehicle's turning capabilities by managing wind flow and reducing pressure differences.
Implementation Method 1
the extension portions closing a gap between the bumper and the radiator are arranged between the bumper and the radiator outside the radiator in the vehicle width direction
Implementation Method 2
turning performance-improvement portions gradually spreading outward in the vehicle width direction toward the vehicle rear and configured to improve turning performance of the vehicle

AI summary
A rough terrain vehicle capable of maintaining the cooling performance of a radiator is disclosed herein. A rough terrain vehicle in which a radiator is arranged between left and right front wheels and so as to be overlapped with the left and right front wheels in the longitudinal direction of the vehicle, and the radiator is surrounded by a front cover, wherein: the front cover includes a grille configured to introduce traveling wind into the radiator, and extension portions extending toward the vehicle rear from both ends of the grille in the vehicle width direction; a bumper is attached to a body frame; the front end of the bumper is arranged closer to the vehicle front than the front ends of the left and right front wheels; the extension portions are arranged between the bumper and the radiator outside the radiator in the vehicle width direction.
