Description

BRACKET ELEMENT ATTACHING WHEEL HOUSING TO THE REAR PARCEL SHELF
FIELD OF TECHNOLOGY
The invention is directed to the field of vehicle acoustics, more particularly to a vehicle comprising at least one bracket element attaching, one of two opposed wheel housings to a rear parcel shelf.
BACKGROUND
Generally, the vehicle body generates noise due to vibrations caused by the roughness of the road. To overcome this prejudice, the car manufacturers tend to increase the stiffness of the vehicle body. However, an improved rigidity of the vehicle body often results in a mass increase.
SUMMARY
The invention has for technical problem to provide a solution to at least one shortcoming of the prior art. More specifically, the invention has for technical problem to damp the noise in a cost effective way.
For this purpose, the invention is directed to a vehicle comprising: two opposed rear wheel housings; a rear parcel shelf extending above and between the two rear wheel housings; wherein the vehicle comprises at least one bracket element extending between one of the rear wheel housings and the rear parcel shelf and being attached to said housing and shelf.
According to a preferred embodiment, the at least one bracket element extends between the wheel housing and the rear parcel shelf vertically or inclined with an angle of less than 30° relative to a vertical direction.
According to a preferred embodiment, the at least one bracket element extends in a main vertical and longitudinal plane.
According to a preferred embodiment, the attachment of the at least one bracket element to the wheel housing is by welding against a side generally vertical wall of said wheel housing.
According to a preferred embodiment, the attachment of the at least one bracket  element to the wheel housing comprises at least spot-welding points distant from each other longitudinally.
According to a preferred embodiment, each of the at least one bracket element is a stamped metal sheet comprising ribs formed thereon.
According to a preferred embodiment, each of the at least one bracket element comprises at least one tab attached against a lower face of the rear parcel shelf.
According to a preferred embodiment, each of the at least one bracket element comprises at least two tabs attached against a lower face of the rear parcel shelf, one of said tabs being attached by welding and the other one being attached by a fastener.
According to a preferred embodiment, the at least one bracket element comprises a left bracket element attached to a corresponding left rear wheel housing of the two rear wheel housings, and a right bracket element attached to a corresponding right rear wheel housing of said two rear wheel housings.
According to a preferred embodiment, the left and right bracket elements have different shapes.
The invention is interesting in that it provides a solution that simplifies the car manufacturing process, since no major structural design change is necessary. The bracket elements can be made out of scraped stamped sheets. There is also no significant increase in the overall weight of the vehicle. The solution is particularly effective in damping noise at low-end audible frequencies.
