FIELD: car industry.
SUBSTANCE: group of inventions relates to cup 1 made by pressing from a metal sheet and forming a concave support for shock-absorbing rack 100, and a motor vehicle with such a cup. The cup contains cone-shaped protrusion 4, bending line 6 forming a boundary between support base 2 of the cup and edges 3, upper surface 7, at least one edge 3, while edge (edges) 3 of the cup forms an essentially cylindrical or conical section around a vertical axis Z, and at least one deepened section 8, 9. Upper surface 7 of the cup, in particular, contains: skirt section 11, and essentially horizontal connecting section 16 connecting skirt section 11 and deepened section 8, 9. Binding line 20 passes through upper surface 7 of the cup, at least partially separating deformation of the skirt section and the cone-shaped protrusion from at least one deepened section 8, 9. Skirt section 11 contains radial bulges 12, 13, 14, 15 passing radially from cone-shaped protrusion 4, and radial bulges 12, 13, 14, 15 are adapted for an increase in the rigidity of skirt section 11 during the deformation.
EFFECT: reduction in weight is provided, while maintaining proper fatigue strength.
