Problems solved by technology

However, in the event of a low-overlap front-end impact, the obstacle could displace the wheel, which could lead to intrusion into the vehicle interior
[0003] The first solution consists in significantly strengthening the front structure, which is not desired because it is bulky and expensive

Embodiment Construction

[0024] In this specification, the terms front, rear, top and bottom refer to the front and rear, top and bottom directions of the vehicle when the front structure is assembled on the vehicle. Axis X, axis Y, axis Z correspond respectively to the longitudinal axis (front to rear), the transverse axis and the vertical axis of the vehicle, the vehicle being located on the ground. Therefore, the vertical direction corresponds to the direction of gravity.

[0025] Substantially parallel, perpendicular or at right angles should be understood to mean directions / angles at most ±20°, even at most ±10° or at most ±5° from parallel, perpendicular or right-angled directions / planes.

[0026] figure 1 Partially shown is a front structure 1 of a motor vehicle which, when assembled on the vehicle, has a longitudinal direction corresponding to the longitudinal direction X of the vehicle. The front structure 1 generally comprises a bracket 2 comprising two side rails 3, a cross member 4 and t...

Abstract

The invention relates to a front structure (1) of a motor vehicle, comprising a carriage (2) comprising two side rails (3), a cross beam (4) and two shock absorbers (5), each shock absorber being fixed to the front end of the side rails (3) in the extension thereof via a plate (6) and to the cross beam (4). At least one shock absorber (5) extends laterally in the transverse direction by a housing (10) having an open cross-section extending from the opposite side to the side facing the other shock absorber, the opening of which is closed by assembly with the shock absorber. The front structure further comprises a deformation-based energy dissipation element (20) associated with the at least one extended shock absorber (5), the element (20) being mounted on an outer side (30) of the side rail (3) to which the extended shock absorber is fixed, aligned in the longitudinal direction with an outer cover of the extended shock absorber.

Description

technical field [0001] The subject of the present invention is a front structure of a motor vehicle with low overlap front impact management. Background technique [0002] The front structure of a motor vehicle typically includes two side rails forming a bracket and a bumper beam linked to the side rails, and a bracket located below the bracket, the bracket being linked to the bracket and designed to receive the vehicle's front end member and Functional link of the powertrain. Typically, a shock absorber (also referred to as a "crash box") is located between the end of each side rail and the end of the bumper beam to protect the structure of the cradle in the event of a low speed impact. The crash box is a deformable hollow part, which makes it possible to at least partially absorb the energy of the front end impact. However, in the event of a low overlap front end impact, the obstacle may displace the wheels, which may result in intrusion into the vehicle interior. [00...
