Rail Vehicle Support Unit Integrating Anti-Climbing and Track Clearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail vehicles have complex, heavy, and expensive track clearer holders that serve only one purpose and do not contribute to other functionalities, making them inefficient and costly.
Innovation Solution
A carrying unit integrated into the rail vehicle structure, featuring a plateau section with anti-climbing means and a roadway clearing receptacle, which provides stability, anti-climbing protection, and serves multiple purposes, including holding a roadway clearing device, while being lightweight and inexpensive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a separate bracket is used to hold the track clearer, then the track clearer can be securely mounted, but the structure becomes complex, heavy, and expensive
Solution Approach 1:
The patent integrates the track clearer holder directly into the vehicle underframe structure, merging the mounting function with the existing structural components. This eliminates the need for separate brackets and reduces overall structural complexity while maintaining secure mounting capability.
Solution Approach 2:
The underframe structure is designed to serve multiple functions: it provides structural support for the vehicle and simultaneously serves as the mounting structure for the track clearer. This multi-functionality reduces the number of separate components needed and simplifies the overall design.
2Strength
If a separate bracket is used to hold the track clearer, then the track clearer can be securely mounted, but the weight and manufacturing cost increase
Solution Approach 1:
The mounting function is merged with the vehicle's existing underframe structure, eliminating the need for additional separate mounting brackets. This integration reduces the total weight by removing redundant structural components while maintaining secure track clearer attachment.
3Ease of manufacture
If a separate bracket is used to hold the track clearer, then the track clearer can be mounted, but the assembly process becomes more complex and costly
Solution Approach 1:
The track clearer holder is integrated into the vehicle underframe as a unified structure, reducing the number of separate parts that need to be assembled. This simplification of the component count and structural integration directly reduces assembly complexity and manufacturing cost.
Solution Approach 2:
The underframe structure performs multiple functions including structural support and track clearer mounting, which reduces the number of specialized components needed and simplifies the overall assembly process by reducing the number of assembly steps required.
4Ease of manufacture
If a simple structure is used for the track clearer holder, then manufacturing is easier and cheaper, but the structure cannot absorb high bending moments
Solution Approach 1:
The vehicle underframe is designed to serve as both the structural support system and the track clearer mounting structure. This multi-functional design allows the use of the existing high-strength underframe components that are already engineered to handle high bending moments, eliminating the need for additional complex reinforcement while maintaining structural integrity.

AI summary
In order to produce a rail vehicle (1) which has a chassis, a vehicle structure (2) and a support unit (5) disposed at the end face (8) of the rail vehicle (1) and which at the same time is comparatively lightweight and economical and which, in addition to supporting a track reamer, can also advantageously perform other tasks, it is proposed that the support unit (5) comprise a plateau section (6) which is part of the vehicle structure (2) and comprises climbing protection means on its end face (7), a track reamer holder (10) for supporting a track reamer being disposed below the plateau section (6) and being rigidly secured thereto.
