Adjustable Exhaust Muffler Support Platform for Vibration Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elastic support mechanisms for exhaust mufflers in work vehicles fail to effectively absorb vibrations when the muffler's position or posture changes relative to the support structure, leading to undue stress on elastic members and reduced vibration absorption efficiency.
Innovation Solution
A flexible support mechanism comprising a support platform, elastic cylindrical members, and bar-shaped members that allow adjustable positioning and tilting of the exhaust muffler along the body frame's lateral and longitudinal directions, enabling the muffler to be securely mounted without excessive stress on the elastic members, thereby enhancing vibration absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional elastic support mechanism with fixed mounting positions is used, then the structure is simple and easy to manufacture, but it cannot effectively absorb vibrations when the exhaust muffler's position or posture changes relative to the support structure
Solution Approach 1:
The patent applies the dynamics principle by making the support platform member adjustable in position along the body frame. The support platform can be repositioned to accommodate changes in the exhaust muffler's position and posture, allowing the elastic support mechanism to maintain effective vibration absorption under varying conditions rather than being fixed in a single location.
Solution Approach 2:
The support mechanism is segmented into distinct components: the support structure, the adjustable support platform member, and the elastic cylindrical members. This segmentation allows each component to perform its specific function independently, with the support platform being adjustable while the elastic members provide vibration absorption, resolving the contradiction between adaptability and simplicity.
2Adaptability or versatility
If the exhaust muffler position or posture changes due to product error or assembly error, then manufacturing flexibility is improved, but undue stress is applied to the elastic members reducing their ability to absorb vibration
Solution Approach 1:
The support platform member's adjustability allows it to dynamically adapt to different exhaust muffler positions and postures. By repositioning the support platform to align with the elastic cylindrical members, the system maintains proper stress distribution on the elastic members even when the exhaust muffler position varies due to manufacturing tolerances or assembly errors.
Solution Approach 2:
The support platform member acts as an intermediary between the support structure and the elastic cylindrical members. It provides an adjustable mounting surface that can be positioned to ensure the elastic members are properly aligned with the exhaust muffler, thereby preventing undue stress while accommodating position variations.
3Reliability
If multiple elastic support points are provided at right/left side edges, then vibration absorption coverage is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The adjustable support platform member serves multiple functions: it provides mounting for elastic cylindrical members at different positions, accommodates variations in exhaust muffler placement, and maintains proper alignment. This multi-functionality consolidates what would otherwise require multiple fixed support structures, simplifying assembly while maintaining comprehensive vibration absorption coverage.

AI summary
A work vehicle is disclosed that includes an elastic support mechanism for supporting an exhaust muffler. The elastic support mechanism includes a support platform member, elastic cylindrical members and a bar-shaped member. The support platform member is supported by a rear-linking frame bar to adjust a position of the support platform member along one of lateral and longitudinal directions of the body frame. An elastic cylindrical member is supported by one of the support platform member and the exhaust muffler. The elastic cylindrical member has an axis extending along the other of the lateral and longitudinal directions, and is supported at a single position, in a direction of the axis, of one of the support platform member and the exhaust muffler. A bar-shaped member supported by the other of the support platform member and the exhaust muffler is fitted into the elastic cylindrical member to be supported by the elastic cylindrical member.
