Adjustable Gripping Pocket for Commercial Vehicle Rail Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional commercial vehicle bodies face dimensional inaccuracies during manufacturing, leading to costly mechanical reworking and assembly adjustments to meet UIC specifications for railway loading, due to unavoidable tolerances in the manufacturing process.
Innovation Solution
The gripping pocket is designed to be fixed in a variable position on the longitudinal beam, allowing for individual adjustment through a gripping pocket holder that can be aligned transversely or angularly, with screw connections and eccentric adapter disks for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If gripping pockets are designed as welded or screwed structures with integral gripping edges, then the structure is simple and strong, but dimensional inaccuracies occur due to manufacturing tolerances requiring costly mechanical reworking
Solution Approach 1:
The gripping pocket is divided into separate components: the gripping pocket holder (5) attached to the longitudinal beam (4) and the gripping pocket (1) attached to the holder. This segmentation allows each component to be manufactured independently with standard tolerances, then assembled together to achieve the required dimensional accuracy for the gripping edge (1.1).
Solution Approach 2:
The gripping pocket holder (5) serves as an intermediary component between the longitudinal beam (4) and the gripping pocket (1). This mediator enables precise positioning and adjustment of the gripping edge (1.1) relative to the beam, compensating for manufacturing tolerances without requiring expensive mechanical reworking of the final assembly.
2Ease of operation
If gripping edges are fixed in position during manufacturing, then assembly is simple, but subsequent adjustment requires extensive mechanical retrofitting work
Solution Approach 1:
The gripping pocket (1) is designed with adjustable positioning capabilities on the gripping pocket holder (5) through screw connections (3) and hole recesses (6). This dynamic design allows the gripping pocket to be repositioned as needed during assembly or maintenance, providing flexibility without requiring complex adjustment mechanisms.
Solution Approach 2:
The position of the gripping pocket (1) on the longitudinal beam (4) can be varied by changing the insertion position of screws (3) into different hole recesses (6) on the gripping pocket holder (5). This parameter change approach enables flexible positioning while maintaining a relatively simple structural design, avoiding the need for extensive mechanical retrofitting.
3Manufacturing precision
If gripping pockets are made adjustable to compensate for tolerances, then dimensional accuracy is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is localized to the gripping pocket holder (5) and gripping pocket (1) assembly, rather than requiring system-wide adjustments. The holder incorporates specific features (hole recesses (6), screw connections (3)) that enable precise positioning of the gripping edge (1.1) while keeping the rest of the commercial vehicle body structure simple and unchanged.

AI summary
Commercial vehicle body for road vehicles, in particular semi-trailers or swap bodies, with a commercial vehicle chassis having longitudinal crossmembers 4, on which at least one gripping pocket 1 comprising a gripping edge 1.1 is provided for the purpose of rail loading of the commercial vehicle body. In order to be able to adapt this commercial vehicle body cost-effectively to the requirements of the UIC rules, it is provided that the gripping pocket 1 is fixed in a positionally adjustable manner to the longitudinal crossmember 4 of the commercial vehicle body (Fig. 1).
