Description

Family of motor vehicles with rear cross member of identical flag

  The present invention relates to a family of motor vehicles of the type comprising a first vehicle and a second vehicle, the first vehicle having a first flag provided with a first rear end, and a box having a first rear cross member on which the first rear end is in support ; the first rear cross member being distinct from the first flag; the second vehicle having a second flag having a second rear end; the second flag being structurally different from the first flag. It is known, in the construction of a motor vehicle, to equip, depending on the versions, the flag of a vehicle with a sheet metal element or a glass or composite material element to form the roof of the vehicle . To secure such elements to the body of the motor vehicle, a rear cross is created to support the roof at the rear top of the vehicle. In a vehicle version comprising a sheet metal roof, the cross member conventionally comprises the folded rear edge of the roof itself and a lower cross member integral with the roof and carried at its two lateral ends by the vehicle body. In a vehicle version comprising a declination of the pavilion in a glass roof or composite material, the cross member comprises a lower cross member and a lining of the cross member, the flag being secured to the liner.

  It follows that, on the assembly line of a motor vehicle, two different body structures are necessary to equip a vehicle with either a sheet metal roof, or a glass roof or composite material, the one unlined, the other lined. This aspect significantly complicates the manufacture of vehicles comprising variations of pavilions made of sheet metal or glass or composite material. The invention aims to simplify the manufacture of the variations of this vehicle.

For this, the second vehicle comprises a second rear cross member structurally identical to the first rear cross member, and in that the second rear end bears on the second rear crossmember. According to other features: the first cross-member and the second cross-member comprise a concave-shaped lower element oriented to present its concavity facing the first pavilion or the second pavilion, and a lining of the lower element also of concave shape and oriented to present its concavity facing the cross member, the liner including a bearing base for the first rear end of the first flag or the second rear end of the second flag; - the lower element has no support base for the first and second pavilions; the lower element and the lining respectively have a respective front end and a rear end through which the cross-member and the liner are made integral, forming a hollow cross-member whose cross section has a closed contour of substantially rectangular shape; the second rear end comprises a tab, overlapping externally, and at least partially, the second rear crossmember. - At least one vehicle has a rear flap hinged relative to the body in the vicinity of the first cross or the second cross, the rear flap overlapping at least partially the base; at least one vehicle comprises a rear flap articulated with respect to the body in the vicinity of the first crossmember or the second cross member, and a hubcap integral with the first crossmember or the second crossmember, which hubcap is disposed externally between the first crossmember and the second crossmember; rear end of the first roof or the second rear end of the second roof and the rear wing; The first cross-member or the second cross-member comprises a rear gutter; 2909352 3 - the first flag is made of glass or composite material, and the first rear end is fixed by a glue joint on the base of the first cross; - The second flag is sheet metal, and the second rear end 5 is welded to the support base of the second cross. The solution to the technical problem substantially simplifies the manufacture of a vehicle comprising pavilions declination sheet or glass or composite material. The invention and its advantages will be better understood on reading the following description, given by way of example only, and with reference to the accompanying drawings, in which: Figure 1 is a rear perspective view of a vehicle of the family of motor vehicles according to the invention; 2 is a diagrammatic view in longitudinal section of the rear portion of a first horn of a first vehicle of the motor vehicle family according to the invention, the view being taken according to section II-II of FIG. ; Figure 3 is a schematic view in longitudinal section of the rear portion of a second roof of a second vehicle of the family of motor vehicles according to the invention; - Figure 4 is a view similar to Figure 3 showing a first variant of the rear portion of the second flag of the second vehicle; Figure 5 is a view similar to Figure 3 showing a second variant of the rear portion of the second flag of the second vehicle; Figure 6 is a view similar to Figure 3 showing the two extreme positions of a rear flap of the second vehicle of the family of motor vehicles according to the invention; Figure 7 is a view similar to Figure 4 showing the two extreme positions of a rear flap of the second vehicle of the family of motor vehicles according to the invention. In Figures 1-7, the X, Y, Z axis system defines the conventional orientation of a vehicle in which: the X axis is the longitudinal axis of the vehicle, oriented from rear to front; the Y axis is the transverse axis of the vehicle, oriented from right to left; and the Z axis is the vertical axis of the vehicle, oriented from bottom to top.

In the following description, the orientation and position terms refer to this X, Y, Z axis system. In FIG. 1 is shown a first vehicle 10 comprising a body 12 and a shutter. 14 is articulated relative to the body 12. The hinge hinges are not shown for the sake of clarity in FIGS. 1 to 5. A horn 16 extends backwards and forwards on the upper part of the body. 12 of the first vehicle 10 to form the roof. The flag 16 of the first vehicle is a flag made of glass or composite material which includes a rear end 17.

A cross-member 18, visible in FIG. 2, disposed transversely along the Y-Y axis. It comprises a lower member 20 and an upper lining 22 of the lower member 20. The cross member 18 is connected at its two lateral ends to the body 12 of the vehicle. The rear flap 14 comprises a front edge 24 disposed longitudinally in the extension of the roof 16, at a short distance from the rear end 17 of the roof. The lower element 20 of the crosspiece 18 is of substantially concave shape, and oriented to present its concavity facing the first roof 16.

The lower element 20 comprises, from front to rear, a front end 26 substantially parallel to the horn 16, a first section 28 disposed substantially parallel to the vertical axis ZZ, a second section 30 disposed substantially parallel to the longitudinal axis XX, and a rear end 32 substantially L-shaped. The lining 22 of the lower cross member 18 is also concave, and oriented to present its concavity 5 facing the lower member 20. The liner 22 comprises, from front to rear, a front end 34 parallel to the front end 26 of the lower element 20, a first section 36 disposed substantially parallel to the longitudinal axis XX in the extension of the front end. 34, a second section 38 disposed substantially parallel to the vertical axis ZZ, a third section 40 in an arc and a rear end 42, L-shaped, say placed parallel to the rear end 32 of the lower element 20. The lower element 20 and the lining 22 are integral with each other respectively by their front ends 26 and 34 as well as by their rear ends 32 and 42. The lower member 20 and the liner 22 thus form a hollow crossmember 18 whose cross section has a closed contour of substantially rectangular shape. The third section 40 of the liner 22 forms a rear gutter for collecting and discharging rainwater from the roof 16. An interior volume 44 is present between the liner 22 of the lower transom member 18 and lining 46 of the rear flap 14. The roof flap 16 of the first vehicle comprises, at its rear end 17, a centering peg 48, oriented towards the passenger compartment of the vehicle and engaged in a slot 49 formed on the first section 36 of the vehicle. lining 22 of the lower element 20 of the crosspiece 18, the centering pin 48 positioning the roof 16 longitudinally and transversely to the lining 22 of the lower element 20.

The first section 36 of the lining 22 of the lower element 20 of the crosspiece 18 serves as a base for supporting the roof 16 by means of a glue joint 50 joining the roof 16 to the first section 36 of the lining 22. The first section 36 constitutes the sole support of the flag 16.

The lower element 20 is, in fact, devoid of support base for the flag 16. The flag 16 extends, longitudinally, substantially on the front half of the first section 36 of the lining 22 of the lower element 20 of the cross member 18. The front edge 24 of the rear flap 14 extends longitudinally substantially over the rear half of the same first section 36, at a short distance from the end 17 of the roof 16. Due to the overlap C of the edge before 24 of the rear flap 14 on the first section 36 of the liner 22, the interior volume 44 is not accessible visually from outside the vehicle. In Figure 3 is shown an upper rear portion of a box and an upper portion of a rear flap 114 of a second vehicle of the family of motor vehicles according to the invention. The elements identical to those of FIG. 2 keep their references increased by 100. This second vehicle comprises a crossmember 118, identical to crossmember 18 structurally, the latter possibly differing only in color. The horn 160 is a sheet metal bell, which extends substantially in the first front half of the first section 136 of the liner 122 of the lower member 120 of the cross member 118. The horn 160 is extended at the rear by a shoulder 162 substantially parallel to the vertical axis ZZ, the recess 162 to make up the dimension along the vertical axis ZZ corresponding to the thickness of the roof 16 glass or composite material added the thickness of the adhesive joint 50 set 25 on the first vehicle of the family of motor vehicles. A rear end tab 164, disposed substantially along the longitudinal axis XX, extends the recess 162 and secures the roof 160 to the cross 118. The rear end tab 164 is assembled to the first section 136 of the liner 122 of the lower element 120 of the cross 118, either by electric welding points and sealing putty, or by brazing, the latter also sealing.

As before, the interior volume 144 is not visually accessible. Although the second vehicle is equipped with a roof plate 160 different sheet 16 glass or composite material of the first vehicle, the second vehicle is equipped with a cross 118 of the same type as the cross 18 of the first vehicle. The first section 136 constitutes the sole support of the flag 160. The lower member 120 is, in fact, devoid of support base for the flag 160.

In the case of the second vehicle, the thicknesses and shades of sheet steel 160 and the liner 122 of the cross member 118 are independent of each other. Thus, the dimensioning of the cross 118 in terms of rigidity and / or mass is optimally achieved. Indeed, it is not necessary to increase the weight of the flag 160 by thickening of the sheet in the case where an increase in stiffness is requested on the rear cross member 118 by increasing the thickness of the liner 122, as this was the case in the state of the art of a sheet metal roof. FIG. 4 shows a variant of the arrangement of FIG. 3. The elements identical to those of FIG. 3 keep their numerical references increased by 100 relative to those of FIG. 3. A hubcap 270, comprising a part providing the finish between the end tab 264 of the horn 260 and the front edge 280 crimped of the rear flap 214, is disposed, at the rear of the horn 260, substantially on the second rear half of the first section 236 of the liner 222 218. The hubcap 270 is secured to the cross member 218 and / or the flag 260. The size of the trim 270 along the vertical axis ZZ is substantially identical to that of the recess 262 of the flag 260.

The front edge 280 of the rear flap 214 is disposed in the extension of the hubcap 270 and at a distance therefrom. The front edge 280 of the rear door 214 is also remote longitudinally, a clearance J, the second section 238 of the liner 222 2909352 8 of the cross member 218. The rear end 272 of the hubcap 270 is disposed in rear longitudinal projection relative to the second section 238 of the liner 222, and reduces the clearance J so as to limit the visual access to the interior volume 244.

FIG. 5 shows a variant of FIG. 4, and the elements identical to this same FIG. 4 retain their numerical references increased by 100 with respect to those of FIG. 4. The embellisher 390 has a clearance 392 on its half. upper rear. Faced with this clearance 392, the front edge 400 of the rear flap 314 occupies the free space cleared, and is partially overlapped on the rear half of the first section 336 of the liner 322. Thus, the interior volume 344 is not accessible visually. The variant of the invention comprising a hubcap is described above in the context of a sheet metal roof. It also applies to a declination of the glass roof or composite material. In Figure 6 is shown the upper rear portion of the second vehicle of Figure 3 wherein the rear flap 114 is movable between its closed position shown in bold lines and its extreme open position shown in phantom. During this opening phase, the front edge 124 of the rear flap 114 describes a circular arc of center A, so that the front edge 124 does not interfere with either the cross 118 or the flag 160 in amount above flag 160.

The center of rotation A is thus optimally arranged with respect to the closing position of the rear flap 114, in front of the front edge 124 of the rear flap 114 when the front edge 124 is in its position behind the recess 162 of the 160, and substantially within the hollow volume of the cross 118.

The front edge 124 moves from its position behind the recess 162 of the roof 160 to its extreme open position, above the roof 160, substantially perpendicular to the center of rotation A. It is used to this movement, gooseneck hinges whose fixed knuckle 166 is secured to the first section 128 of the lower element 120 of the cross 118, and whose movable knuckle 168 is integral with the lining 146 of the rear flap 114. Thus, the leading edge 124 describes an arc when opening the rear flap 114 so that the leading edge 124 moves upwardly above the horn 160. In Figure 7 the upper rear portion is shown of the second vehicle of Figure 4 in which the rear flap 114 is movable between its closed position shown in bold lines and its extreme open position shown in phantom. During this opening phase, the front edge 224 of the rear flap 214 describes a circular arc of center B, so that the front edge 280 does not interfere with the lining 222 of the cross 118 down to the rear gutter.

The center of rotation B is thus optimally arranged with respect to the closing position of the rear flap 214, behind the front edge 280 of the rear flap 214 when the front edge 280 is in its position behind the hubcap. 270, and substantially in the interior volume 244. The front edge 280 moves from its position behind the recess 262 of the roof 260 to its extreme open position, facing the third section 240 of the liner 222 of the crosses 218, at the bottom of rear gutter. For this movement, simple hinges are used whose fixed knuckle 266 is integral with the rear end 242 of the second section 238 of the liner 222 of the crossmember 218, and whose movable knuckle 268 is integral with the lining 246 of the rear flap 214. Thus, the front edge 280 describes an arc when opening the rear flap 214, so that the front edge 280 moves downward towards the rear gutter.

Thanks to the invention, the subassembly rear cross member, also incorporating the rear gutter function is identical for the declensions of a sheet metal roof or flag glass or composite material. It is no longer necessary to manage two different counter frames on the motor vehicle assembly line, in order to equip a vehicle with either a sheet metal roof or a glass or composite roof. The manufacture of the variations of such a vehicle is thus simplified.
