Definitions

• the invention relates to a motor vehicle fender, comprising a concave wall adapted to be fixed to the vehicle body and to partially surround a wheel of the vehicle.
• the invention aims to improve the acoustic insulation of the passenger compartment vis-à-vis the outside, at the wheels of the vehicle, regardless of the suspension debate supported by the vehicle.
• the subject of the invention is a mudguard of the type set out above, further comprising a soundproofing wall, connected to said concave wall via a deformable link, and adapted to be attached to a part of the ground connection associated with the wheel.
• the deformable connection comprises an accordion-folded flap
• the shutter is adapted to form a soundproofing screen around the wheel axle; - the mudguard is made in one piece; and
• the mudguard is made of plastic, in particular by injection molding or blowing.
• the invention also relates to a motor vehicle comprising at least one mudguard of the type described above.
• FIG. 1 is a schematic perspective view of a motor vehicle mudguard, according to a first embodiment of the invention
• FIG. 2 is a diagrammatic view in axial section, in the vertical plane 2-2 shown in FIG. 1, of a motor vehicle wheel, a associated ground connection, and the mudguard of Figure 1 mounted on the vehicle body;
• FIG. 3 is a view similar to Figure 1, illustrating a second embodiment of the invention.
• a mudguard 1 of a motor vehicle according to a first embodiment of the invention.
• This mudguard 1 essentially comprises a concave wall 3, a plate 5 for attachment to the bodywork, a soundproofing wall 7, and a connecting flap 9 between the concave wall 3 and the sound-insulating wall 7.
• concave wall 3 has a generally curved shape intended to partially surround a wheel of the vehicle, when the mudguard is attached to the bodywork.
• the concave wall 3 comprises an upper band 11 having a section, in a longitudinal and vertical central plane P, substantially C-shaped.
• the concave wall 3 also comprises, closing a side face of the C, a closure wall 13 also concave.
• the fixing plate 5 is integral with the upper band 11, and extends from one end of the C.
• the insulation wall 7 is essentially flat and extends parallel to the longitudinal plane P. It is connected by its upper edge to the lower edge of the closure wall 13, through the flap 9.
• the insulation wall 7 is furthermore formed with a fixing light 15 to a ground connection piece associated with the wheel.
• the shutter 9 is folded in accordion, according to parallel folds oriented longitudinally, parallel to the lower edge of the closure wall 13 and the upper edge of the insulation wall 7.
• the mudguard 1 is made in one piece, for example injected or blown plastic material.
• the concave wall 3 and the fixing plate 5 are provided with a plurality of holes 17, or more generally fasteners, for fixing the mudguard 1 to the body (or bodywork) of the vehicle.
• Figure 2 there is shown the mudguard 1 of Figure 1 mounted on the body 20 of a vehicle.
• the concave wall 3 is fixed rigidly, via the fixing holes 17, to the body 20 so as to partially surround the associated wheel 21.
• the wheel 21 is connected to the body by means of a ground connection shown schematically under the reference 23, capable of deflection and displacement relative to the body 20.
• the general reference numeral 23 also designates in particular one of the parts of the ground connection, such as the wishbone.
• the suspension triangle is engaged through the light 15, so that the insulation wall 7 is fixed to this suspension triangle 23.
• the insulating wall 7 moves in solidarity by biasing the flap 9 in corresponding deformation (in stretching or contraction ).
• the insulating wall 7 and the flap 9 constitute sound insulation screens which limit the propagation along the wheel axles of the vibratory sound phenomena originating in the vicinity of the wheel.
• the insulating wall 7 and the flap 9 thus contribute, by accompanying displacements in displacement of the wheel and the connection to the ground, to limit the propagation of certain noises towards the interior of the passenger compartment.
• FIG 3 there is shown a mudguard 101 according to a second embodiment of the invention.
• This mudguard 101 is similar in its constitution to the mudguard 1 described above, the concave wall 3 and the fixing plate 5 being similar or identical to the previous ones.
• the mudguard 101 differs from the mudguard 1 described above only in that the insulation wall 107 and the flap 9 extend along the lower edge of the closure wall 13 over a longer length, and so continuous on the lower end edge of the band 1 1, the opposite side to the fixing plate 5.
• the wall 107 and the flap 109 are bent with a portion extending substantially along a longitudinal plane, and a portion extending substantially in a transverse plane.
