Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorber devices for vehicles, particularly rail vehicles, are either complex or require excessive space, failing to efficiently utilize available space while providing an application-oriented design.
Innovation Solution
A vehicle absorber device featuring at least two absorber elements, a holding device, and a collision bracket that allows the collision bar to be moved from an operating position to a stowed position, aligning with the coupling plane to free space for coupling without increasing the vehicle's length, and incorporating a guide device for vertical displacement and a damping mechanism to manage collision forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collision bar is permanently positioned in the operating position to absorb collision forces, then collision force absorption is improved, but coupling space is blocked and vehicle length increases
Solution Approach 1:
The collision bar is designed to be movable between an operating position (where it absorbs collision forces) and a stowed position (where it clears the coupling plane for vehicle coupling). The holding device enables the collision bar to be dynamically repositioned based on operational requirements, resolving the contradiction between maintaining collision protection and enabling coupling operations.
Solution Approach 2:
The collision bar is moved vertically out of the coupling plane into a stowed position above the vehicle body, rather than being displaced longitudinally. This dimensional change allows the coupling device to operate in the original space without interference from the collision bar, while the collision bar remains positioned to absorb forces when needed.
2Reliability
If absorber elements are added to improve collision force absorption, then safety is improved, but device complexity and space requirements increase
Solution Approach 1:
The absorber elements are positioned within the vehicle body structure, nested along the longitudinal axis inside the vehicle frame. This integration allows the absorber elements to be housed within existing structural spaces rather than requiring external additions, thereby improving collision force absorption without proportionally increasing device complexity or external dimensions.

AI summary
The present invention relates to an absorber device for a vehicle, in particular for a rail vehicle. The objective is to provide an improved absorber device for a vehicle. The absorber device according to the invention comprises at least two absorber elements, a holding device, and a collision bar for absorbing collision displacements and/or collision forces. The vehicle frame has at least one force application section for supporting and/or bracing the absorber elements and a coupling bearing. The absorber elements are designed such that they can be mounted to the force application sections of the vehicle frame. The collision bar has two ends through which collision forces transmitted into the collision bar can be transferred to the absorber elements. This is possible when the collision bar is in its intended operating position.According to the invention, the absorber device is designed such that the collision bar can be moved into a designated stowing position.
