Stiffening arrangement for a forward structure of a motor vehicle

摘要

A stiffening arrangement (22) for a forward structure (10) of a motor vehicle has a mounting bracket (20) for mounting a motor vehicle radiator. A shear field (24) is connected to the mounting bracket (20) to dissipate shear forces. A right stiffening strut (28) connects the shear field (24) to a right suspension-strut dome (16) and supports the mounting bracket (20) on the right suspension-strut dome (16), and a left stiffening strut (30) connects the shear field (24) to a left suspension-strut dome (18) and supports the mounting bracket (20) on the left suspension-strut dome (18). Thus, a major part of the crumple zone of the forward structure (10) provided for a frontal crash can be utilized, so that the risk of damage to engine components in an engine bay of the forward structure (10) is reduced and vibrational comfort for the driver is improved.

1. A stiffening arrangement for a forward structure of a motor vehicle, comprising:
a mounting bracket for the mounting of a motor vehicle radiator on the front side, a shear field connected to the mounting bracket and which serves for the dissipation of shear forces, a right stiffening strut connected to the shear field and to a right suspension-strut dome for supporting the mounting bracket on the right suspension-strut dome, and a left stiffening strut connected to the shear field and to a left suspension-strut dome and for supporting the mounting bracket on the left suspension-strut dome, wherein the shear field has a plurality of open areas, and, in relation to an overall area Ages, delimited by an outer edge of the shear field, a sum of opening areas of the openings A0 is defined as: 0.20≦A0/Ages≦0.80.
