BACKGROUND / PRIOR ART
. .
Front fender is assembled .w. i.th. vehiclebody on both sides by means of multiple
. . . . . . .
mountings iricluding a mounting (M) as in "fig 1 adjacent to the 'front door of
vehicle .
. .
The fender surface facing to.wards .the' front door while assembling is having
non unifo. rm. depth (A,B,C) as. ..i llustrated i n f ig 2 with respect to the visible
surface (side surface)' (SI) of the 'fender . a$ . in fig 1. his is because the fender,
. . . .
mounting suiface (M) is required to be moved away from the styling surface for
mou.nting on the ,vehicle body. . . . . . . . , - ..
. .
This gives rise greater depth (B) at the mounLg (M) with an integrated bead
(Dl) as compared to. th.e .de pt,h... o n bot.h . . sides (A and C), wherein A=C. This . .
. .
creates in forma.b.ili.ty. t hereby: producing deformation on the A-surface . I . ' . .
(visible surface) in proximity to c;tline i.e. line of joining.
As the depth (B) >Depth (A and LC).,t herefore the touching point. o. fCAM in the '
course of restriking operation followihg CAM operation is ndt uniform. This
eventually leads. t'o .deformation qf ,the fen.d. .e r panel in the visible sqrface as
. . .
shown in fig..3 .. . . . . . . . .
In order to provide a solution to the above problem, the mounting (M) can be
. .
removed. However, it would be difficult t o control the. gap and level difference
. . . . . .
between the fr. ont, .d. -o or and fender. . .
. .
...
29:. . ;-. . In view of the above, a novel. . Eront fender is'required to be devised which can . .
serve the pu;pose without producing deformation and gap. Hence, the present
,\'.
invention has been intr-oduced. . . . .

The invention makes a disclosure regarding a newly devised front fender of
vehicle, which can prevent' deformat'ion .t h.e reof: in the exposed surface during
. .
manufacturing without affecting, the styling. intent.
. . . .
Now reference may be made :to fig 4. A flat. s. heet (P)' having width, equivalent to
. . . ..., .
that of the fender iurface is introduced above the fender mounting surface (M).
. I .
This sheet connects two intermediate points (PI, P2) of the fender surface (S).
. . . . . . _ ' , , . . . .. .
. . , . . . .
~hus... :. thfee nder,mounti.n g. su.. rface (M) is located between the flat sheet (P) and
inverse flange (F) of said fender. So that provision of said sheet can cover the
difference in-depth between said intermediate points to obtain uniform depth
throughout i.e. A=B=C.
The aforesaid provision'. fesu.lts 'in .improved formability without causing
deformation. on . A-Surface :. ( S.f yling surface) thereby addressing issues of
. . . "
existing front fender. . . . .. ..
Referring to fig 5, during restriking operation of CAM, angle ,E in section X-X
. - .
should always be greater thanor equal toangle D as best seen in fig 5.So that
CAM movement in. . this area is. not affected. The present invention meets the . . .. .
criteria. . . . .
. .
. ..
In addition to the above, there is provision of atleast one auxiliary bead (B) in
conjunction with. .. existing bead (Dl), which is integrated to the mounting ,
sul-face (M) so as to enhance the. stiffness of the fender mounting surface.Size
of the. bead is designed ' con. s. idering .the fender mounting bolt torquing gun
. .. .
requirement'. ~urther,t. he number of beads is provided as per the stiffness
' .. ' * .
:(rt requirement 'of the': mounting' surface i.e. Number of beads a Stiffness of
mounting surface.
The joining of all faces shown.,in fig 6 is required to. be made' with smooth
transition so as to ensure bitter formability. When. the dimension F is larger, . . .
. . . . : . . I - -. . . .
then the Angle G (Shown in Sect: Y-Y) is also larger to ensure smooth transition
, . . .
for better formability.
. . . Advantageous Features . . . . . . .
- .Maintenance .o .f visible ,surface as per the styling intent.
. . . .
- 1'mpr6vement in stiffne~sof fende. r. mounting. .
- ~voids'defoimationo f fend'er on visible surface thereof.
- Improved formability of the front fender. . - ..
