Aluminium@ alloy bracket for attachment of elastic suspension element

摘要

The aluminium alloy bracket (14) is produced by extrusion and has at least one opening (40) oriented in the extrusion direction. It also has a two rows of alternating protrusions and depressions, with one row covering at least a part of its fixing surface (38) next to the suspension element (12), and the other row covering at least a part of its free surface (48,50,52) exposed to an atmosphere. The corrugated sections on the bracket surface(380 have distance between the corrugation tops and bottoms varying from 0.3-1.00 mm, with the lateral distance between them varying from 0.5-2.0 mm. in cross section the corrugations have a form made up of arcs.
