GRIPPER-ARM INTERFACE OF FRAME AND SIDE OR END PANEL IN OPEN-CAR BODY MADE FROM ALUMINIUM ALLOYS Russian patent published in 2009 - IPC B61D17/04 B61D3/00 F16B2/24 

FIELD: mechanics.

SUBSTANCE: gripper-arm interface is represented with elastic lock-on connection. The profile of frame bracing (1) has two L-shaped external projections (4). There are two projections (3) on the ends of side or end panels (2), which are directed opposite to the frame bracing. Two external L-shaped projections are directed differently. Besides projections of side or end panels are located inside the panel. Distance (L) from working surface of panel projections contact to the nearest stiffening rib is defined from the mathematical expression. When elastic lock is latched, mutual location of frame and body elements is fixed. It helps to prevent deformation and mutual displacement of elements during welding.

EFFECT: improved reliability of interface operation due to weld joint unloading as a result of complete or partial load transfer though projections of interfaced elements.
