Solution Overview
Problem
Existing agricultural utility vehicle side stabilizer mounting systems face challenges in efficiently managing mechanical loads and reducing frictional forces, leading to increased material usage and complexity.
Innovation Solution
The implementation of a bearing bracket system with high and transverse connecting means that extend along the vehicle's longitudinal and transverse directions, respectively, to provide additional mechanical connections between the axle housing and the vehicle's supporting structure, allowing for efficient force component transmission and reduced mechanical load on the bearing bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bearing bracket is firmly connected to the axle housing using suitable clamping elements, then the mechanical connection is achieved, but the frictional forces increase and the mechanical load on the bearing bracket increases
Solution Approach 1:
The bearing bracket is divided into multiple connection points along its longitudinal direction. Instead of a single firm connection, multiple distributed connections are created through connecting means extending along the longitudinal direction of the vehicle, segmenting the force transmission paths and reducing concentrated frictional forces.
Solution Approach 2:
The connecting means extend not only in the longitudinal direction but also in the transverse direction of the vehicle. This multi-dimensional arrangement distributes the mechanical load across different spatial dimensions, reducing the frictional force concentration at any single connection point between the bearing bracket and axle housing.
2Strength
If the bearing bracket is designed with sufficient load-bearing capacity, then the mechanical strength is ensured, but the material usage increases and the design becomes more complex
Solution Approach 1:
The bearing bracket structure is segmented into multiple connection points distributed along its longitudinal direction. This segmentation allows the use of smaller, simpler connecting elements at each point while collectively achieving the required overall load-bearing capacity, reducing both material usage and design complexity.
Solution Approach 2:
By extending connecting means in both longitudinal and transverse directions, the load-bearing capacity is achieved through spatial distribution rather than increasing the size or complexity of individual components. This multi-dimensional connection approach maintains strength while simplifying the overall design.
3Strength
If the bearing bracket is designed with sufficient load-bearing capacity, then the mechanical strength is ensured, but the ground clearance is reduced
Solution Approach 1:
The connecting means extend in the transverse direction of the vehicle in addition to the longitudinal direction. This transverse extension provides the necessary load-bearing capacity and stability without increasing the longitudinal footprint of the bearing bracket, thereby preserving ground clearance.
4Reliability
If the bearing bracket is firmly connected to the axle housing, then the mechanical connection is achieved, but the assembly process becomes more difficult
Solution Approach 1:
The bearing bracket is equipped with multiple connecting means distributed along its longitudinal direction. This segmentation allows for modular assembly where each connecting means can be installed independently, simplifying the overall assembly process while maintaining reliable mechanical connection.
