Adjustable Ground Clearance Agricultural Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural vehicles have fixed ground clearance, limiting their ability to operate in varying crop heights during intercultural operations, as increasing clearance requires a permanent change or switching to a different vehicle, which is inefficient.
Innovation Solution
An agricultural vehicle with adjustable ground clearance, featuring a vehicular structure that can be locked into multiple positions using locking elements and an extension arrangement between wheels and axles, allowing for flexible height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a customized high ground clearance tractor is built, then it can operate in tall crops, but it cannot perform like a conventional tractor
Solution Approach 1:
The patent applies segmentation by dividing the adjustment mechanism into separate components: the extension arrangement (which provides the height increase) and the locking mechanism (which secures the position). This modular approach allows the high clearance capability to be added as a separate system rather than redesigning the entire vehicle, thus reducing overall complexity
2Ease of operation
If the ground clearance is fixed, then the vehicle structure is simple, but the operator must switch vehicles or make permanent changes to operate in different crop heights
Solution Approach 1:
The patent applies preliminary action by providing multiple pre-configured locking positions (first locking position and second locking position) that are prepared in advance. The operator can directly select and lock into the appropriate position for the current crop height without needing to perform modifications or switch vehicles, saving time and effort

AI summary
An agricultural vehicle V with adjustable ground clearance and a method 70 thereof is provided. The agricultural vehicle V includes a vehicular structure C, a pair of front wheels FW, a pair of rear wheels RW, at least one front axle, at least one rear axle, a pair of final drive housings FH, a plurality of locking elements LP and an extension arrangement E. The vehicular structure C is configured to be moved between at least one lowered position in which each final drive housing FH is locked to the vehicular structure C at corresponding first locking positions, and at least one raised position in which each final drive housing FH is locked to the vehicular structure C at corresponding second locking positions. The extension arrangement E adapted to be coupled between corresponding front wheels FW and a front axle when vehicular structure C is at the raised position.
