Articulated Track Wheel Support for Ski Piste Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ski piste preparation crawled vehicles experience undesired vibrations due to inadequate connection between wheel assemblies and the frame.
Innovation Solution
The vehicle features an articulated supporting device with elastic or variable stiffness components connecting the wheels, allowing for relative movement and reducing vibration transmission, comprising a first and second supporting element connected through a hinge or elastic structure, and a shock absorber with variable stiffness and geometry to absorb hits and adjust wheel position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wheels are rigidly connected to the frame, then the structural strength is improved, but the vibrations are increased
Solution Approach 1:
The patent changes the connection parameter from rigid to articulated, allowing the supporting device to have degrees of freedom while maintaining structural integrity. The articulated connection enables the wheels to move independently to absorb vibrations while the overall structure remains strong.
Solution Approach 2:
The patent introduces dynamic capability to the wheel support system through articulated connections, allowing the supporting device to adapt its configuration in response to terrain variations. This dynamic adjustment reduces vibrations transmitted to the frame while maintaining structural strength.
2Stability of the object's composition
If the wheels are rigidly connected to the frame, then the structural stability is improved, but the comfort is worsened
Solution Approach 1:
The patent changes the connection parameter from rigid to articulated, allowing the supporting device to have degrees of freedom while maintaining structural integrity. The articulated connection enables the wheels to move independently to absorb vibrations while the overall structure remains strong.
Solution Approach 2:
The patent introduces dynamic capability to the wheel support system through articulated connections, allowing the supporting device to adapt its configuration in response to terrain variations. This dynamic adjustment reduces vibrations transmitted to the frame while maintaining structural strength.
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
This configuration reduces vibrations by allowing the wheels to move independently, improving stability and comfort during operation by effectively absorbing shocks and adjusting to the snow surface.
Implementation Method 1
the first supporting element and the second supporting element are connected to one another in an elastically flexible manner
Implementation Method 2
the first and the second supporting element are connected to one another through a shock absorber
