Work Vehicle Cover Structure for Debris Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work vehicles, such as feller bunchers, face operational disruptions due to debris like leaves, branches, and wood chips falling onto moving parts and coupling areas between the vehicle body and work implement, potentially impacting the movement of the work implement.
Innovation Solution
A work vehicle design featuring a cover structure with a work implement cover, a chassis side cover, a top cover, and an underside cover that are hingedly coupled to the vehicle body and work implement, creating an overlapping enclosure to prevent debris from entering the coupling area and affecting the operation of the work implement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the work implement is movably coupled to the vehicle body without additional covers, then the structure remains simple and easy to manufacture, but debris can fall into the coupling portion and affect the movement of the work implement
Solution Approach 1:
The protective cover system is divided into multiple segments: a first cover coupled to the work implement, a second cover hingedly coupled to the vehicle body, and a third cover hingedly coupled to either the vehicle body or work implement. These segmented covers work together to protect the coupling portion while maintaining structural simplicity and ease of manufacture.
Solution Approach 2:
The second and third covers are designed to be hinged rather than fixed, allowing them to move dynamically as the work implement moves relative to the vehicle body. This dynamic design ensures continuous protection of the coupling portion while accommodating the movable coupling between work implement and vehicle body.
2Object-affected harmful factors
If covers are added to protect the coupling portion from debris, then the protection against debris is improved, but the ease of operation and maintenance of the work implement is reduced
Solution Approach 1:
The hinged design of the second and third covers allows them to be easily opened and closed. During normal operation, the covers remain closed to protect against debris. During maintenance or operation requiring access, the hinged covers can be opened without complex fastening mechanisms, maintaining ease of operation while providing protection.
Solution Approach 2:
The cover system acts as an intermediary protective barrier between the debris environment and the coupling portion. The hinged mechanism serves as a mediator that allows controlled access when needed while maintaining protection during normal operation, balancing debris protection with operational accessibility.

AI summary
A work vehicle includes a vehicle body, a work implement, a first cover, and a second cover. The work implement is movably coupled to the vehicle body. The first cover is coupled to the work implement. The second cover is hingedly coupled to the vehicle body and is at least partially overlappingly disposed on the first cover.
