Rail Vehicle Partition Mounting Hook for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex assembly and vibration transmission issues with rigidly connected wall-like separating devices in rail vehicles, such as dividing walls or partition doors, complicate the installation and operation of these devices while maintaining ground clearance.
Innovation Solution
A holder with a downwardly curved hook is used to attach the separating device to a cantilever seat support, allowing for easy assembly and tolerance compensation, with elastomer decoupling to manage vibrations, and optional rigid connections for added stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid connection is used to attach wall-like separating devices to the car body shell, then structural stability is improved, but assembly complexity and tolerance compensation become problematic
Solution Approach 1:
The patent introduces a holder as an intermediary component between the wall-like separating device and the seat support. This holder with hook-shaped end acts as a mediator that simplifies the connection while maintaining stability, allowing easy assembly through hooking into an eyelet without complex rigid fastening procedures.
Solution Approach 2:
The patent changes the connection parameter from rigid fixed connection to a flexible hook-based connection. The holder's hook-shaped end can engage with the eyelet in a simplified manner, and the connection allows for movement in the z-direction to accommodate tolerance variations, transforming the connection characteristics to resolve the contradiction.
2Force
If rigid connection is used for wall-like separating devices, then power transmission during operation is improved, but assembly effort and tolerance compensation become complex
Solution Approach 1:
The holder serves as an intermediary that transmits forces between the wall-like separating device and the seat support. The hook-shaped connection efficiently transmits longitudinal forces (x-direction) while simplifying the assembly process compared to rigid connections, and allows vertical movement (z-direction) for tolerance compensation.
Solution Approach 2:
The patent introduces dynamic characteristics to the connection by allowing the holder to move vertically relative to the eyelet. This dynamic capability enables the connection to adapt to tolerance variations during assembly while maintaining effective force transmission during operation, resolving the contradiction between assembly ease and power transmission.
3Strength
If rigid connection is used to mount separating devices, then structural integrity is improved, but vibration transmission increases
Solution Approach 1:
The holder acts as a vibration-dampening intermediary between the wall-like separating device and the seat support. While maintaining structural integrity through the hook connection, it introduces flexibility that reduces the transmission of vibrations to the vehicle structure, converting harmful rigid force transmission into damped vibrations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the assembly of wall-like separating devices and effectively reduces vibration transmission, enhancing the installation process and operational stability of rail vehicle partitions while maintaining high ground clearance.
Implementation Method 1
The end of the holder designed as a downwardly curved hook can be decoupled from the eyelet of the seat support by means of an elastomer layer. This means that vibrations are only transmitted with (strong) dampening.
Implementation Method 2
The end of the holder designed as a downwardly curved hook can be decoupled from the eyelet of the seat support by means of an elastomer layer.

AI summary
A rail vehicle with a wall-like separating device. The invention relates to a rail vehicle with at least one seat support (12, 22, 29) which runs in the transverse direction of the rail vehicle and is designed as a cantilever support connected exclusively to a side wall of the rail vehicle, and with a wall-like separating device (14, 24) which is adjacent to the seat support (12, 22, 29) and is arranged parallel to the seat support (12, 22, 29), wherein the separating device (14, 24) is supported on the seat support (12, 22, 29) by means of a holder (15, 25, 31) arranged horizontally in the longitudinal direction of the rail vehicle, wherein an end of the holder (15, 25, 31) that faces the seat support (12, 22, 29) is designed as a downwardly curved hook (16, 26, 30) which engages from above in an eye (13, 23, 28) attached rigidly to the seat support (12, 22, 29).
