Low Mount Three Point Engine Pump Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power machines, such as skid steer loaders and tracked vehicles, experience significant vibration due to their engine and drive systems, which are not effectively isolated from the frame, leading to unwanted vibration transfer.
Innovation Solution
A mounting system with first and second connection points positioned in close proximity to the center of gravity and a third connection point distally located, allowing the power system to be securely attached to the frame, thereby minimizing vibration transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the power system is attached to the frame using conventional mounting methods, then the structure is simple and easy to manufacture, but vibration is transferred significantly from the power system to the frame
Solution Approach 1:
The mounting system divides the attachment function into multiple connection points (first, second, and third connection points) positioned at specific locations relative to the power system's center of gravity. This segmentation allows different parts of the mounting system to handle different aspects of vibration isolation and structural support, reducing overall vibration transfer while maintaining manageable complexity
Solution Approach 2:
The mounting system acts as an intermediary between the power system and the frame, with connection points strategically positioned to create optimal attachment geometry. This intermediary structure isolates the power system from direct rigid connection to the frame, reducing vibration transfer while maintaining structural integrity
2Stability of the object's composition
If the connection points are positioned away from the center of gravity, then the mounting structure is simpler, but the power system becomes less stable and experiences more vibration
Solution Approach 1:
The mounting system applies local quality by positioning the first and second connection points in close proximity to the center of gravity of the power system, while the third connection point is positioned distally. This non-uniform distribution of connection points optimizes stability by concentrating attachment near the mass center where it most effectively reduces vibration and improves balance
3Object-affected harmful factors
If the power system is mounted with multiple connection points near the center of gravity, then vibration isolation is improved, but the mounting system becomes more complex
Solution Approach 1:
The attachment system is segmented into three distinct connection points with specific positioning requirements. The first and second connection points are positioned in close proximity to the center of gravity, while the third connection point is positioned distally. This segmentation creates an effective vibration isolation geometry without requiring complex isolation components
Solution Approach 2:
Instead of positioning all connection points away from the center of gravity for structural simplicity, the invention inverts the conventional approach by positioning two connection points near the center of gravity and one distally. This inverted configuration optimizes vibration isolation by creating favorable attachment geometry relative to the mass distribution

AI summary
An attachment system to fasten a power system to a frame of a loader is discussed. The frame has a proximal end, a distal end, and first and second opposing sides. The power system has an engine, and an arrangement of one or more hydraulic pumps attached to the engine. The attachment system has first and second connection points positioned in close proximity to a center of gravity of the power system relative to the direction between the proximal and distal ends of the loader. The attachment system also has a third connection point positioned distally from the first and second connection points, wherein the positions of the first, second and third connection points connect the power system to the frame to allow most of the weight of the power system to be loaded onto the first and second connection points.
