Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for power transmission between the running gear and car body of rail vehicles are complex, requiring significant installation space, limiting accessibility, and complicating the detachment and control of the car body, while also not efficiently accommodating manufacturing tolerances.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If complex solutions with links, pivots, and lemniscate linkages are used for longitudinal driving, then force transmission between running gear and car body is achieved, but device complexity increases and installation space requirements increase
Solution Approach 1:
The patent extracts the essential function of longitudinal force transmission from the complex system of links and pivots, isolating it into a dedicated longitudinal driving buffer that handles only force transmission, while the secondary suspension handles only spring movements. This separation eliminates the need for complex multi-functional mechanisms.
Solution Approach 2:
The patent segments the coupled system into independent functional components: the longitudinal driving buffer for force transmission and the secondary suspension for spring movements. This segmentation allows each component to be optimized for its specific function without the complexity of integrated mechanisms.
2Force
If complex solutions with multiple connecting elements are used, then longitudinal driving capability is achieved, but installation space increases reducing availability for other elements
Solution Approach 1:
The patent extracts the longitudinal force transmission function from the complex spatial arrangement of multiple connecting elements, concentrating it into a single linear buffer component that occupies minimal installation space while maintaining full force transmission capability.
3Force
If multiple connecting elements are used for longitudinal driving, then force transmission is achieved, but accessibility for control and maintenance deteriorates
Solution Approach 1:
The patent extracts the control and maintenance functions from the complex assembly of connected elements, isolating them to the accessible end faces of the longitudinal driving buffer where sliding sections can be easily inspected, adjusted, and maintained without disassembling multiple components.
4Force
If complex fixation methods are used for longitudinal entrainment, then force transmission is ensured, but detachment of car body from chassis becomes complicated
Solution Approach 1:
The patent employs a dynamic sliding contact between the sliding section and longitudinal driving buffer that provides secure force transmission during operation but allows for simple detachment by removing the sliding section from the buffer's end face, eliminating the need to loosen multiple fixed connections.
Solution Approach 2:
The patent extracts the detachment function from the complex fixation system, allowing the sliding section to be independently removed from the longitudinal driving buffer without affecting other connecting elements, thereby simplifying car body detachment procedures.

AI summary
The invention relates to a device for transmitting a force between a chassis (1) and a body (2) of a rail vehicle. The aim of the invention is to provide a structurally simple, space-saving device which allows spring movements and rotational movements of the body (2) relative to the chassis (1). According to the invention, this is achieved in that at least one first traction link buffer (9), which has a first end face (16), and at least one second traction link buffer (10), which has a second end face (17), are fixed to the chassis (1). The first end face (16) is spaced from the second end face (17) in a longitudinal direction (3) of the rail vehicle. The two end faces (16, 17) point in at least approximately opposite directions, and a stop plate (11) with sliding portions (18) which are mutually spaced in the longitudinal direction (3) is provided on the body (2), said end faces (16, 17) of the traction link buffers (9, 10) resting against the sliding portions in a slidable manner at least along some sections.
