Elastic Bracket for Work Vehicle Post-Treatment Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work vehicles with post-treatment apparatuses mounted on the vehicle frame experience excessive load on connecting pipes during excavation, leading to poor rear visibility due to elevated positions of these apparatuses when mounted above the engine.
Innovation Solution
A bracket system that elastically supports the engine and post-treatment apparatuses, keeping them at or below the radiator's height, with differential support sections and an anti-sway component to distribute loads and reduce vibration, thereby minimizing the load on connecting pipes and maintaining rear visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the post-treatment apparatus is supported by a component connected to the vehicle frame, then the exhaust treatment function is achieved, but an excessive load is applied to the connecting pipe when the vehicle frame is twisted during excavation work
Solution Approach 1:
A bracket is introduced as an intermediary component between the vehicle frame and the post-treatment apparatus. This bracket is elastically supported by the vehicle frame, allowing it to absorb frame twisting movements and prevent excessive loads from being transmitted to the connecting pipe while still maintaining the exhaust treatment function.
Solution Approach 2:
The bracket's elastic support changes the mechanical coupling parameters between the vehicle frame and post-treatment apparatus. By allowing controlled movement and deformation in the bracket, the system transforms rigid connections into flexible ones, reducing stress concentration on the connecting pipe during frame twisting.
2Strength
If the post-treatment apparatus is mounted on top of the engine, then the connecting pipe load is reduced, but the upper surface of the outer cover is heightened and rear visibility becomes poor
Solution Approach 1:
Instead of mounting the post-treatment apparatus vertically on top of the engine (one-dimensional height increase), the apparatus is positioned horizontally in front of the radiator. This dimensional shift maintains lower overall height of the outer cover while still achieving the goal of reducing connecting pipe load through the elastic bracket support.
3Ease of repair
If the post-treatment apparatus is positioned higher to improve engine access, then maintenance becomes easier, but rear visibility is reduced
Solution Approach 1:
The support structure is segmented into the bracket (elastically supported by the frame) and the post-treatment apparatus (supported by the bracket). This segmentation allows the apparatus to be positioned optimally for both visibility and accessibility, with the bracket providing the necessary support and movement absorption without requiring high mounting position.

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 the load on connecting pipes, allows for shorter pipe lengths, and improves rear visibility by keeping the upper surface of the outer cover horizontal, enhancing operational efficiency and visibility during vehicle use.
Implementation Method 1
The bracket is positioned in front of the radiator and is elastically supported by the vehicle frame
Implementation Method 2
The mounting bracket may include a damper mounting section between the one edge which supports the post-treatment apparatus support bracket and the other edge

AI summary
A work vehicle includes a vehicle frame, a radiator, an engine, a first post-treatment apparatus, a second post-treatment apparatus, and a bracket. The engine is provided in front of the radiator. The first post-treatment apparatus and the second post-treatment apparatus are positioned in front of the radiator and treat exhaust from the engine. The bracket is positioned in front of the radiator and is elastically supported by the vehicle frame. The bracket supports the engine, the first post-treatment apparatus, and the second post-treatment apparatus. Both the highest position of the first post-treatment apparatus and the highest position of the second post-treatment apparatus are no higher than the highest position of the radiator.
