Rail Vehicle Level Control Piston Tangential Hydraulic Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing level control systems for rail vehicles are not space-efficient and require complex installation and maintenance due to their structural design, which complicates both operation and servicing.
Innovation Solution
A level control system with a collar-like shoulder and tangentially arranged hydraulic connectors, allowing for a space-saving design where the level control piston is partially movable within the cylinder, reducing structural height and simplifying installation and maintenance by integrating functional components directly into the cylinder and piston geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional level control systems are used, then the vehicle level can be adjusted, but the structural space height is large and installation/maintenance is complex
Solution Approach 1:
The hydraulic connector is integrated directly into the piston structure, merging two previously separate components (piston and hydraulic connector) into one unified element. This reduces the number of separate parts, simplifies assembly, and decreases the overall structural space height while maintaining full functionality for level adjustment
Solution Approach 2:
The piston is designed to serve multiple functions: it acts as both the moving element for level adjustment and as the hydraulic connector for fluid supply. This multi-functionality eliminates the need for separate hydraulic connection components, reducing complexity and space requirements
2Volume of moving object
If hydraulic connectors are arranged radially, then fluid connection is achieved, but the structural space height increases
Solution Approach 1:
The hydraulic connector is positioned at the radial end face of the piston rather than on the cylindrical surface, utilizing a different spatial dimension for connection. This dimensional repositioning reduces the structural space height while maintaining efficient fluid connection capability

AI summary
A level control system adjusts the level of a rail vehicle, and includes at least one level control cylinder and a level control piston. The level control piston is at least partly received in the level control cylinder in a movable manner. The level control system has at least one first hydraulic connection, wherein the level control cylinder or the level control piston has a collared shoulder, in which at least one first fluid channel connected to the first hydraulic connection is arranged. At least one first attachment for receiving the first hydraulic connection is provided along the collared shoulder, the first attachment, being arranged on the collared shoulder tangentially to the longitudinal axis of the level control cylinder or of the level control piston such that at least one tangential external fluid connection on the collared shoulder can be connected to the at least one first hydraulic connection.
