Guide Device Halves Plug-in Slide Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices for belt-driven conical-pulley transmissions face challenges in simplifying the connection between halves, ensuring reliable assembly, and maintaining producibility while avoiding assembly errors and gaps.
Innovation Solution
A plug-in and slide connection mechanism using L-shaped hooks and cutouts allows for a form-locked connection between guide device halves, ensuring a one-click assembly and increased holding force without the need for measuring or testing pulling-out force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a two-part guide rail with locating pins and latching hooks is used, then the guide device can be assembled in sections, but the connection complexity and assembly error risk increase
Solution Approach 1:
The guide rail is divided into two separate halves that can be manufactured independently and then connected during assembly. This segmentation allows for easier manufacturing of each half while maintaining the overall functionality of the guide device.
Solution Approach 2:
The locating pin and latching hook features are integrated directly into the guide rail halves themselves rather than being separate components. This merging reduces the total number of parts and simplifies the connection system while maintaining assembly capability.
2Reliability
If traditional connecting systems with multiple features are used, then connection reliability can be achieved, but assembly time and process complexity increase
Solution Approach 1:
The guide rail halves are designed with pre-formed locating pins, locating pin receptacles, latching hooks, and latching bows that are integral to the structure. This preliminary preparation of connection features eliminates the need for additional assembly steps or separate fastening components, enabling rapid one-click assembly while ensuring reliable connection.
3Strength
If guide rail halves are connected with multiple connection features, then connection strength can be improved, but manufacturing complexity increases
Solution Approach 1:
Multiple connection functions (locating, latching, securing) are merged into integral features of the guide rail halves themselves. The locating pins and latching hooks are formed as part of the guide rail structure during manufacturing, eliminating the need for separate fastening components while maintaining strong connection capability.

AI summary
A guide device for guiding an endless torque-transmitting member of a belt-driven, conical-pulley transmission. The device includes an outer guide section, and an inner guide section that is spaced from the outer guide section and between which guide sections the endless torque-transmitting member is guidable in a direction of travel of that member. The device is formed from two halves that are connected to each other by a plug-in and slide connection arrangement, in order to improve the guide device structurally, functionally, and from a producibility standpoint.
