Pivoting Support Wheel for Reversible Plough with Gravity-Actuated Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting support wheels for mounted reversible plows are complex, heavy, and require significant assembly effort, with uncontrolled swiveling movements leading to high stress and potential impact during operation.
Innovation Solution
A pivoting support wheel design featuring a swivel stop on the support strut that moves with the swiveling movement, ensuring a favorable center of gravity and automatic unlocking/locking, combined with a joint axis transverse to the working direction and a damper for controlled pivoting, along with a variable support strut and adjustable counterstop for depth adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydraulic cylinders and hydraulic lines are used to control the pivoting support wheel, then the ease of operation is improved, but the device complexity, weight, and installation effort increase
Solution Approach 1:
The patent extracts and removes the hydraulic system (cylinders, lines, valves) from the plow structure, replacing it with a purely mechanical pivoting support wheel that rotates freely on its axis. This elimination of hydraulic components directly reduces device complexity, weight, and installation effort while maintaining the essential function of guiding the plow in working depth
Solution Approach 2:
The pivoting support wheel is designed to perform its own positioning function through passive mechanical means - it freely rotates on its pivot axis to accommodate plow orientation changes without requiring external hydraulic actuation. The wheel self-adjusts to the plow's working position through its inherent rotational freedom, eliminating the need for complex control systems
2Ease of operation
If the pivoting support wheel is designed to swivel forwards more than 180°, then the ease of operation during turning is improved, but the risk of inadvertent pivoting increases requiring additional control mechanisms
Solution Approach 1:
The pivoting support wheel is designed with free rotational capability in all directions, creating an equipotential state where the wheel can naturally assume any angular position without resistance or control intervention. This passive rotational freedom allows the wheel to automatically adapt to plow orientation changes during turning operations without requiring active control mechanisms or depth limitation systems
3Device complexity
If the pivoting support wheel swivels backwards less than 180°, then the device simplicity is improved, but the depth limitation control becomes more difficult requiring adjusted panning movement or disabled depth limitation
Solution Approach 1:
The pivoting support wheel is designed with dynamic rotational freedom, allowing it to pivot in any direction and through any angle as needed during plow operation. This dynamic capability enables the wheel to accommodate both forward and backward plow orientations without mechanical constraints, eliminating the need for adjusted panning movements or disabled depth limitation while maintaining simple construction
4Ease of operation
If uncontrolled swiveling movement is allowed during turning, then the ease of operation is improved, but high dynamic forces occur leading to high stress on the assembly
Solution Approach 1:
The patent introduces a damper as an intermediary element between the pivoting support wheel and its mounting structure. This damper absorbs and dissipates the high dynamic forces generated during uncontrolled swiveling movements, protecting the assembly from excessive stress while allowing the wheel to maintain its free, uncontrolled rotational capability for ease of operation during turning
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies construction and assembly, reduces weight, and ensures controlled and reliable pivoting movements, minimizing stress and impact, while allowing for easy depth adjustment without additional components.
Implementation Method 1
the swivel stop is arranged on the support strut, which is always moved with the swiveling movement of the swivel support wheel... If the mounted reversible plow is lifted, the pivoting support wheel pivots more or less forwards and downwards around its pivot axis before the start of the turning process due to its gravity
Implementation Method 2
the support strut has a damper which is designed to decelerate and/or dampen the pivoting process of the pivotable part of the pivoting support wheel

AI summary
The invention relates to a mounted reversible plough comprising a pivoting support wheel, in which the working depth guide can be set by a support strut of the pivoting support wheel. Said support strut is connected to the wheel rod and the support frame of the pivoting support wheel and is fitted with a pivoting stop which pivots in an unlocked position due to the pivoting force during the rotational process and pivots back into position before the end of said rotation process, the position in which the working depth of the mounted reversible plough is limited. The fact that the pivoting stop is arranged on the support strut enables, during the rotational process of the mounted reversible plough, centre of gravity positions of the pivoting stop in relation to the guide axis, which ensure a safe and early pivoting of the pivoting stop in the unlocked position and/or stop position, to be reached.
