Muffler Mount Layout for Work Vehicle Vibration Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing muffler attachment structures for work vehicles with engines often fail to effectively absorb vibrations, leading to potential damage to the mufflers.
Innovation Solution
The proposed configuration attaches the muffler to an attachment target via two anti-vibration mounts, strategically positioned on the muffler to absorb vibrations efficiently, even with a small number of mounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the muffler is attached to the attachment target via anti-vibration mounts, then vibrations are absorbed and damage to the muffler is prevented, but the number of anti-vibration mounts increases and the attachment structure becomes more complex
Solution Approach 1:
The attachment structure is segmented into two distinct anti-vibration mounts positioned at different locations on the muffler body. The first anti-vibration mount is positioned on a first portion of the muffler in the longitudinal direction and on a first portion in the up-down direction, while the second anti-vibration mount is positioned on a second portion in the longitudinal direction and on a second portion in the up-down direction. This segmentation allows each mount to handle specific vibration components independently, improving overall vibration absorption effectiveness while maintaining a manageable number of mounts.
Solution Approach 2:
The patent transitions from a single-dimension mounting approach to a multi-dimensional arrangement. By positioning mounts based on both longitudinal direction and up-down direction coordinates, the attachment structure utilizes spatial distribution in multiple dimensions. This dimensional approach maximizes vibration absorption with minimal mounts by strategically placing them where they can most effectively counteract vibration forces from different directions.
2Reliability
If multiple anti-vibration mounts are used to absorb vibrations, then muffler protection is improved, but the weight of the attachment system increases
Solution Approach 1:
The patent extracts and addresses only the most critical vibration absorption requirements by using precisely two anti-vibration mounts positioned at optimal locations. Rather than uniformly distributing multiple mounts throughout the muffler structure, the invention identifies and implements mounts only where they are most needed based on the longitudinal and up-down direction positioning criteria, thereby minimizing the number of mounts and associated weight while maintaining effective vibration protection.
3Device complexity
If anti-vibration mounts are strategically positioned, then vibration absorption is improved with fewer mounts, but the design and installation precision requirements increase
Solution Approach 1:
The patent applies local quality by specifying precise positioning criteria for each anti-vibration mount based on its location on the muffler body. The first anti-vibration mount is positioned on a first portion in the longitudinal direction and on a first portion in the up-down direction, while the second is positioned on a second portion in the longitudinal direction and on a second portion in the up-down direction. This localized positioning approach ensures that each mount is placed optimally for its specific location, maximizing vibration absorption effectiveness while maintaining clear, actionable positioning guidelines that balance precision requirements with practical manufacturability.

AI summary
A work vehicle includes a first anti-vibration mount and a second anti-vibration mount with which a muffler is attached to an attachment target while being oriented with its longitudinal direction extending along a horizontal plane. The first anti-vibration mount is located on a portion on one side of the muffler in the longitudinal direction and on a portion on one side of the muffler in an up-down direction. The second anti-vibration mount is located on a portion on the other side of the muffler in the longitudinal direction and on a portion on the other side of the muffler in the up-down direction.
