Rotatable Rail Wheel Set Transport Device for Tight Curves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for receiving and transporting wheel sets of rail vehicles struggle to navigate small curve radii without derailing, as they lack rotatable side parts and adaptable connections for optimal cornering.
Innovation Solution
The device features rotatable superstructures relative to substructures, connected via rods or other components, allowing for adjustable steering angles and secure wheel accommodation, enabling smooth navigation through tight curves and varying track widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device uses fixed side parts without rotation capability, then the structure is simple and stable, but it cannot navigate small curve radii without derailing
Solution Approach 1:
The side parts are designed with rotatable superstructures relative to substructures, allowing the device to dynamically adjust its geometry during cornering. This rotational capability enables the superstructure to pivot and adapt to curved paths, resolving the contradiction between structural stability and adaptability to small curve radii.
Solution Approach 2:
The device is divided into distinct substructure and superstructure components that can rotate relative to each other. This segmentation allows independent movement of each part, enabling the superstructure to adjust its orientation for cornering while the substructure maintains stable support, thus achieving both cornering stability and adaptability.
2Adaptability or versatility
If the device has rotatable superstructures relative to substructures, then it can navigate small curve radii effectively, but the device complexity increases
Solution Approach 1:
The rotatable connection between superstructure and substructure introduces dynamic adaptability, allowing the device to navigate small curves by pivoting the superstructure. This single rotational degree of freedom provides the necessary adaptability without requiring multiple complex mechanisms, thus managing device complexity while achieving curve navigation capability.
3Stability of the object's composition
If the side parts are connected rigidly, then the device maintains structural stability, but it cannot adjust to varying track widths and gauges
Solution Approach 1:
The rotatable connection between superstructure and substructure provides dynamic adjustability, allowing the device to adapt to different rail gauges and track widths by changing the relative orientation of the side parts. This maintains structural stability during operation while enabling configuration changes for different track specifications.

AI summary
The invention relates to a device (1) for receiving and for transporting at least one wheel set of a rail vehicle, comprising a first lateral part (2) and a second lateral part (2') which are spaced apart from one another in the transverse direction (Y), wherein both lateral parts (2, 2') are connected to one another, wherein both lateral parts (2, 2') each have an upper structure (4, 4') and a lower structure (3, 3'), wherein both lower structures (3, 3') have at least one carrying wheel (5, 5', 5'', 5''') with which the device (1) can be moved in the longitudinal direction (X), and wherein both upper structures (4, 4') have a receiving means (6, 6) in which a wheel (10) of a wheel set can be received. In order to allow for a transporting of wheel sets even when travelling on a curve, in particular with small curve radiuses, according to the invention, the upper structure (4, 4') of a lateral part (2, 2') is rotatably mounted relative to the lower structure (3, 3') of the same lateral part (2, 2').
