Dry Coupling Receiving Part Plug-in Control Sleeve Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry clutch receiving parts face challenges with complex and clumsy designs due to strong compressive stress, impaired pressure safety, and inefficient assembly and disassembly processes, particularly with screw or press connections that require special tools and result in manufacturing damage and prolonged production times.
Innovation Solution
A detachable, loose plug-in form-fitting connection between the receiving part housing and the control sleeve is established, using pairs of plug-in elements that secure the control sleeve against axial movement and allow for precise angular positioning, reducing play and enhancing pressure security without the need for force-fit connections, thus simplifying assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw or press connections are used to connect the control sleeve to the receiving part housing, then pressure safety is improved, but device complexity and manufacturing time increase
Solution Approach 1:
The connection structure is segmented into separate receiving part housing and control sleeve components that can be independently manufactured and assembled through a simple plug-in connection, eliminating the need for complex screw or press connections while maintaining pressure safety
Solution Approach 2:
The connection function and pressure containment function are merged into a single integrated plug-in connection structure, where the control sleeve directly engages with the receiving part housing to provide both mechanical connection and pressure sealing simultaneously
2Reliability
If screw or press connections are used to connect the control sleeve to the receiving part housing, then pressure safety is improved, but manufacturing time and tool usage increase
Solution Approach 1:
The control sleeve and receiving part housing are designed with pre-configured plug-in connection features that enable direct assembly without requiring preliminary alignment or special tools, significantly reducing assembly time and improving productivity
Solution Approach 2:
The plug-in connection structure is designed to be self-aligning and self-securing, where the control sleeve automatically engages with the receiving part housing through its own geometric features without requiring external tools or complex assembly procedures
3Reliability
If force-fit connections are used to connect the control sleeve to the receiving part housing, then pressure safety is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
Instead of using force-fit connections that require significant assembly force, the invention inverts the approach by using a loose plug-in connection where components engage through complementary geometric features that guide automatic alignment and secure connection without forcing
4Strength
If special tools are used for press or welded connections, then connection strength is improved, but manufacturing precision and risk of damage increase
Solution Approach 1:
The plug-in connection features are designed with self-aligning geometric characteristics that automatically guide the control sleeve into the correct position relative to the receiving part housing during assembly, eliminating the need for special alignment tools and preventing manufacturing damage

AI summary
The invention relates to a dry-coupling receiving part (6) of a dry coupling (100) for fluid, the receiving part comprising: a receiving-part housing (61); a valve device (1) arranged in the housing and having a guide seat ring (2) and a valve body (3); and a receiving-part control device (5), which has a control sleeve (51) that can be rotated about a receiving-part axis (60) in connection with control elements (55) and by means of which the valve body (3) can be moved into a valve opening position (402) and a valve closing position (401). The receiving-part housing (61) and the guide seat ring (2) have connector elements (28, 66) for coupling to a dry coupling plug-in part (7). A releasable, floating, plug-in interlocking connection (8) is formed between the receiving-part housing (61) and the control sleeve (51), this connection rotationally coupling the receiving-part housing (61) and the control sleeve (51) and securing the control sleeve (51) against the receiving part housing (61), preventing axial movement towards the housing end (611) on the coupling side. At least one plug-in element pair (80, 82) of the plug-in interlocking connection (8) interlockingly couples the receiving-part housing (61) and the control sleeve (51) in an offset angular position, in which an initial position of the control elements (55), which is associated with the closed position (401) of the valve, and coupling connection positions for the connector elements (28, 66) are defined. At least one second plug-in element pair (80, 81, 83) of the plug-in interlocking connection (8) defines the secured axial position. A dry coupling (100) for fluid is formed by the dry-coupling receiving part (6) and a dry-coupling plug-in part (7) connected thereto, the latter having a plug-in-part valve body (751) of a plug-in-part valve (75). The receiving-part valve body (3) and the plug-in-part valve body (751) rest against one another in an axially displaceable sliding union which can be brought out of associated valve closing positions (401, 701), against a restoring force, into valve opening positions (402, 702).
