Compact Coupling Device Actuator Layout for Narrow-Space Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tiltrotators for working machines face difficulties in operation in narrow spaces due to the packing of their components, limiting maneuverability and ease of use.
Innovation Solution
A coupling device with actuators positioned on the same end and arranged to be narrower than the width of the second coupler body, allowing for a more compact design that facilitates tilting and rotating of the working implement, with a slewing arrangement using a worm gear for rotation and hydraulic actuators for tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If actuators are arranged at different ends of the coupling device, then the structural balance is improved, but the footprint and width of the coupling device increases
Solution Approach 1:
Both actuators are arranged at the same end (first end) of the coupling device, merging their positions to reduce the overall footprint and width of the device while maintaining structural functionality
2Area of stationary object
If actuators are arranged side-by-side, then the width of the coupling device is reduced, but the packing density of components increases
Solution Approach 1:
The actuators are arranged adjacent to each other in a compact configuration, utilizing spatial optimization to reduce width while managing component density through careful dimensional arrangement
3Ease of operation
If the coupling device is designed with narrow footprint, then maneuverability in narrow spaces is improved, but the component layout complexity increases
Solution Approach 1:
The coupling device is divided into distinct functional sections (first coupler body, second coupler body, third coupler body) with actuators concentrated at one end, allowing modular arrangement that reduces footprint while maintaining operational simplicity

AI summary
A coupling device connecting a working implement to a working arm of a working machine. The device has a first coupler body, a second coupler body pivotally mounted to the first coupler body, and a third coupler body rotatably mounted to the second coupler body so as to be rotatable about a second axis. The coupling device includes first and second spaced apart actuators configured to tilt the second coupler body relative to the first coupler body, where the coupling device comprises a first end and a second end, and wherein the first and second actuators are arranged on the first end.
