Front structure for motor vehicle, has front energy absorption part deformable by crushing that is controlled under form of successive ripples along longitudinal axis of front energy absorption part and rear effort transmission part

摘要

The structure has a front bottom track comprising a transversal bumper face-bar beam connected to a support cradle by an extension (10). The extension is formed by an elongated piece comprising a front energy absorption part (20) and a rear effort transmission part (30). The front part is deformable by crushing that is controlled under the form of successive ripples along a longitudinal axis of the front and rear parts. The front part has a body (40) comprising an over-mold made of two plastic materials formed on a longitudinal element that is formed by a metallic tube.
