Towed Implement Transport Axle Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Towed agricultural implements experience undesirable vibrations during field work, leading to instability and disruption, which existing solutions often address with complex and costly damping systems or structural modifications that may introduce additional issues.
Innovation Solution
A simple damping system is integrated into the raised transport axle of towed implements, using a hydraulically actuable lifting mechanism or other damping elements to counteract natural vibrations, stabilizing the device without altering its basic structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If complex damping systems or structural modifications are used to reduce vibrations, then vibration reduction is achieved, but device complexity and cost increase
Solution Approach 1:
The transport axle assembly serves dual functions: it provides transport capability when raised and simultaneously acts as a passive vibration damper through its own suspension elements. The system uses its inherent structural components (spring elements, dampers in the suspension) to counteract vibrations without requiring separate active damping systems.
Solution Approach 2:
The vibration damping function is extracted from the transport axle assembly and applied to the main implement frame. By allowing the transport axle to move independently through its suspension system, the harmful vibrations are isolated and dissipated separately from the main implement structure.
2Object-affected harmful factors
If structural modifications are made to reduce vibrations, then vibration reduction is achieved, but weight distribution and center of gravity may be impaired
Solution Approach 1:
The existing suspension system of the transport axle is utilized for vibration damping purposes without adding separate structural modifications to the main implement frame. The spring elements and dampers already present in the transport axle suspension perform the dual function of supporting the axle and damping vibrations.
3Object-affected harmful factors
If active control systems are used to prevent swinging, then vibration control is improved, but cost and design effort increase significantly
Solution Approach 1:
The passive suspension system with spring elements and dampers automatically counteracts vibrations through its inherent mechanical properties. The system responds to vibrations passively through the natural characteristics of the suspension components without requiring sensors, control units, or active hydraulic systems.
Solution Approach 2:
The spring elements and dampers in the transport axle suspension create controlled mechanical vibrations that counteract the harmful swinging motions. The suspension system allows the transport axle to oscillate in a controlled manner, dissipating energy and reducing the amplitude of harmful vibrations.

AI summary
The combination has a drawing vehicle and towed agricultural cultivation- and/or sawing machines (8, 10) including a variable height adjustable transporting axle (18) with two running wheels (20). The transporting axle is connected with equipment frames (14) by a joint, and a damping unit is arranged between the transporting axle and equipment frames, where the transporting axle forms a vibration damper (28). A damping of the transporting axle is enabled by hydraulic pressure storage (24) in a hydraulic excavation mechanism of the transporting axle. USE : Soil-cultivation combination unit. ADVANTAGE : The combination unit is designed in such a manner that the pitching oscillations of the cultivation equipment, and/or combination unit and sawing machine are minimized, and active control of the hydraulic power lift is enabled with reduced structural complexity and overall cost. DESCRIPTION OF DRAWINGS : The drawing shows a schematic side view of a soil-cultivation combination unit in an operating position with a raised axle. 8, 10 : Towed agricultural cultivation- and/or sawing machines 14 : Equipment frames 18 : Variable height adjustable transporting axle 20 : Running wheels 24 : Hydraulic pressure storage 28 : Vibration damper.
