Mower Suspension Bearing Adjustment for Eccentric Load Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural harvesting machines, particularly mowers, face issues with unintentional tilting of the working assembly due to eccentric displacement of the center of gravity caused by additional equipment, leading to uneven ground contact and increased weight, which complicates ground adaptation and increases manufacturing costs.
Innovation Solution
An adjustable bearing bracket is integrated into the suspension system, allowing the articulated bearing head to be adjusted relative to the working assembly, ensuring the oscillating axis intersects the center of gravity, thereby maintaining balance and uniform ground contact despite eccentric weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional equipment is installed on the working assembly, then functionality and versatility are improved, but the center of gravity becomes eccentrically displaced causing unintentional tilting
Solution Approach 1:
The bearing bracket is made adjustable rather than fixed, allowing the bearing head position to be dynamically changed to compensate for the eccentric center of gravity caused by additional equipment. This enables the system to adapt its configuration to maintain balance while accommodating various functional attachments.
Solution Approach 2:
The position parameter of the bearing head is made variable through the adjustable bearing bracket, allowing the oscillating axis position to be changed relative to the working assembly. This parameter adjustment compensates for the shifted center of gravity and prevents unintentional tilting.
2Stability of the object's composition
If the bearing head is adjusted to compensate for center of gravity displacement, then balance is improved, but device complexity increases
Solution Approach 1:
The bearing bracket is designed with adjustable capability, allowing the bearing head position to be modified to compensate for eccentric center of gravity. This dynamic adjustment feature maintains balance while accommodating various equipment configurations.
3Stability of the object's composition
If counterweights are added to balance the working assembly, then stability is improved, but weight and manufacturing complexity increase
Solution Approach 1:
Instead of adding static counterweights, the invention uses a dynamic solution where the bearing head position can be adjusted to compensate for the shifted center of gravity. This approach maintains balance without increasing the overall weight of the working assembly.
Solution Approach 2:
The position parameter of the bearing head is made variable, allowing the oscillating axis to be relocated to compensate for the eccentric center of gravity. This parameter adjustment achieves balance without adding mass to the system.

AI summary
A suspension and an agricultural harvesting machine, in particular a mower, having a working assembly which is suspended in an oscillating manner by means of the suspension and can be guided over the ground. In the region of an upright axis through the center of gravity of the working assembly, the suspension has a central, articulated bearing head to which the working assembly is fastened. The bearing head has an adjustable bearing bracket for adjusting the bearing head relative to the working assembly in a direction transverse to the upright axis through the center of gravity of the working assembly.
