Guide Lever Cable Routing for Articulated Vehicle Center Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing center bracket systems for multi-articulated vehicles are complex and expensive, failing to reliably guide cables between carriages while allowing necessary freedom of movement, often causing cables to hit the center bracket during vehicle operations.
Innovation Solution
A cost-effective center bracket system featuring a guide lever connected to the center bracket via a first pivot joint and the cable harness via a second pivot joint, with intersecting pivot axes ensuring defined guidance and freedom of movement, utilizing a leaf spring support and roller mechanism to maintain cable stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If cables are routed above the passage in low-floor vehicles, then space utilization is improved, but cables may hit the center bracket during vehicle operations
Solution Approach 1:
A guide lever is introduced as an intermediary component between the cable harness and the center bracket. The guide lever is connected to the center bracket via a first pivot joint and to the cable harness via a second pivot joint, allowing it to mediate the interaction between these two components. This intermediary structure prevents direct contact between the cable harness and center bracket while maintaining proper cable routing above the passage.
2Reliability
If the center bracket is made rigid to prevent cable movement, then cable guidance is improved, but freedom of movement between carriages is restricted
Solution Approach 1:
The guide lever is designed with pivot joints that allow dynamic movement. The first pivot joint connects the guide lever to the center bracket, and the second pivot joint connects it to the cable harness. These pivot joints enable the guide lever to adapt its position dynamically, providing stable cable guidance when needed while allowing freedom of movement between carriages during operation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents undesirable cable movements, ensuring cables do not hit the center bracket, while allowing limited longitudinal movement of the center bracket without forcing the cable harness to move, thus reducing stress and maintaining cable stability across various vehicle operations.

AI summary
The invention relates to a central bracket system for a vehicle joint arranged between a first car and a second car of a multi-section vehicle. The central bracket system comprises a transversely oriented central bracket (20) and a cable harness (21) extending between the first car (14) and the second car (15). The central bracket (15) encloses a passageway (17) intended for passengers. The cable harness (21) is arranged above the passageway (17). According to the invention, the central bracket system includes a guide lever (25) which is connected to the central bracket (20) via a first pivot joint (22, 27) and which is connected to the cable harness (21) via a second pivot joint (29), wherein the axis of the first pivot joint (22, 27) and the axis of the second pivot joint (29) intersect a vertical longitudinal plane.The center bracket system according to the invention can be manufactured cost-effectively and provides reliable guidance for the cable harness (21).
