Definitions
- the invention relates to a motor vehicle body and a corresponding embodiment method.
- a conventional body has two front side door frames, each frame being delimited by a foot, a front foot, a bay jamb and a base beam.
- a front portion of the body further extends from the middle legs, said front part including wheel arches.
- the base rails and the lower parts of the front legs are interconnected via a floor, extending substantially horizontally.
- the front feet are connected to each other by a deck called lower and apron said superior.
- apron said superior.
- the apron has two lateral edges, respectively fixed on each front leg.
- a conventional vehicle body extends along a longitudinal axis A between a rear portion 1 and a front portion 2 for receiving a motor unit.
- the transverse direction is defined by the axis B, extending perpendicular to the axis
- the box comprises a floor formed by a straight floor (not shown) and a left floor 3 each extending substantially horizontally and having an upper face 4 and a lower face 5.
- the box further comprises two underbody 6, arranged on each side of the floor.
- Each spar 6 has a lower face 7 (Figure 2) extending substantially horizontally and an inner face 8 ( Figure 1), that is to say facing the opposite spar or to the cockpit of the body, s' extending substantially vertically.
- Each spar 6 is extended at its front end by a front leg 9, respectively right and left.
- Each front foot has a first portion 10 extending substantially horizontally in the extension of the corresponding underbody 6 and a second portion 1 1 extending upwards, connected to each other by a curved zone 12.
- the first part 10 has a lower face 13 (FIG. 2) extending in the plane of the lower face 7 of the corresponding spar 6.
- Each front foot 9 also has an inner face 14 (FIG. 1) extending in the plane of the inner face 8 of the corresponding spar 6.
- each front leg 9 has a face 15 facing forward and having an area 16, located on the side of the inner face, inclined from the front to the rear and from the inside towards the outside.
- the front feet 9 left and right are connected to each other via a so-called lower apron 17, hereinafter simply called apron.
- the apron has a left lateral edge 18 and a right lateral edge 19, an upper end 20 and a lower end 21.
- the lower end 21 of the deck 17 is fixed to the front of the floor 3, more particularly on the upper face 4 thereof. Particular attention will be paid to the docking or connecting zones between the floor 3 and the corresponding underbody 6 and between the deck 17 and the corresponding front foot 9.
- the body being generally symmetrical, similar landing areas being provided in the right part of the body.
- the left edge of the left floor 3 has a lip 22 extending horizontally.
- the abovementioned lip bears against the lower face 7 of the left spar 6 and against the lower face 13 of the left front foot 9.
- the spacing between the longitudinal members 6 and the spacing between the front legs 9 must be modified. For this, it is possible to slide the lip 22 on the lower faces 7, 13, while maintaining sufficient overlap of the lip 22 thereon.
- the basement spar 6 and the front foot 9 correctly positioned electric weld points can be made in the overlap area to fix the various components relative to each other.
- the left edge 18 of the apron 17 has, in its lower part, a first lip 23 extending substantially vertically upwards, abutting against the inner wall 14 of the front foot 9.
- the left edge of the apron also has, in its upper part, a second lip 24 extending inclined towards the rear and towards the outside. Said lip 24 bears against the inclined zone 16 of the left front foot 9.
- the apron 17 is fixed to the left front foot 9 at the first and second lips 23, 24, via welding points. It is not possible to adjust, before the welding is made, the position, in the transverse direction, of the apron 17 with respect to the left front foot 9.
- the docking areas formed by the first and second lips 23, 24 do not allow, because of their structure and their position, clearance vis-à-vis the corresponding faces of the front foot 9.
- the invention aims to remedy this drawback by proposing a box.
- the invention relates to a motor vehicle body extending along a longitudinal axis between a rear portion and a front portion, comprising at least one front foot and at least one deck mounted on the foot front, characterized in that it comprises means for adjusting the position of the deck relative to the front foot, along a transverse axis.
- the adjustment means thus make it possible to use the same apron for several body widths, that is to say for several types of vehicle. The number of parts needed to make several different models of vehicle is reduced.
- the apron comprises a lateral edge equipped with a positioning lip mounted on one face of the front foot, said lip being intended to adjust the relative position of the apron with respect to said face, along the axis transverse.
- the sliding of the lip along the face of the front foot makes it possible to adjust the positioning of the apron vis-à-vis the front foot.
- the width of the lip is determined according to the clearance to be allowed, a portion of the lip must necessarily bear against the aforementioned face, so as to achieve the fixing of the deck on the front foot, for example by welding.
- the width of the lip is between 40 and 50 mm.
- the front foot is connected to at least one underside beam, at least one floor being mounted on said underbody spar, the deck being further mounted on the floor, at a lower end apron.
- the body comprises a connecting member connected firstly to a stretcher and secondly to the underside beam through the front foot.
- the connecting member comprises an external lateral edge, turned on the side of the front foot, fixed to an intermediate member, itself mounted on the front foot.
- the width of the intermediate member that is to say the dimension thereof in the transverse direction, depends on the type of box to achieve. Indeed, the longer the beams and the front legs are spread, that is to say the larger the body is large, the width of the profile will be important.
- the intermediate member has a generally U-shaped and comprises a first branch attached to the connecting member and a second branch attached to the front foot.
- the floor comprises means for adjusting the position of the floor vis-à-vis the underside of the underframe along the transverse axis.
- the box comprises a first and a second front legs, on which the deck is mounted, respectively at a first and a second edge thereof, at least one of the edges of the deck being equipped with means for adjusting the position of the corresponding edge of the apron vis-à-vis the corresponding front foot, along the transverse axis.
- the invention also relates to a motor vehicle characterized in that it comprises a box according to the invention.
- the invention further relates to a method of producing a car body extending along a longitudinal axis between a rear portion and a front portion, and comprising at least one front foot and at least one apron, said method comprising the following steps :
- the step of fixing the apron to the front foot consists of:
- Figure 3 is a perspective view from below of the body of a vehicle, showing only the docking area of the apron on the front left foot;
- Figure 4 is a sectional view along a transverse plane showing the docking area of the deck and the connecting member on the front foot;
- Figure 5 is a view corresponding to Figure 3, showing a box with a different positioning of the deck vis-à-vis the front foot.
- a connecting member 25 in the form of a bent sheet metal part, is fixed on the apron 17, the floor 3 and the front foot 9.
- the connecting member 25 allows the attachment of a stretcher, not shown.
- the connecting member 25 has more particularly an upper zone 26 fixed on the apron 17, a lower zone 27 fixed on the floor 3 and an edge 28, turned on the side of the front foot corresponding and adapted to be fixed thereon.
- each left edge 18 of the apron is equipped with a lip 29 extending transversely, with a curvature conforming to that of the lower and front faces 13, 15 of the front foot.
- Said faces 13, 15 of the front foot also extending transversely, respectively in substantially horizontal and vertical planes.
- the displacement of the lip 29 vis-à-vis the front foot 9 can be performed to adjust the position of the deck 17 relative to the front foot 9 corresponding.
- the lip 29 can be fixed by welding to the front foot 9.
- the width of the lip is between 40 and 50 mm, preferably 45 mm so as to obtain a sufficient deflection thereof on the front foot, 20 mm remaining further dedicated to the weld.
- the left edge 28 of the connecting member 25 is fixed, either directly to the front foot 9, but on an intermediate member 30, itself fixed on the front foot 9. More particularly, the left edge 28 of the connecting member 25 has a flange extending substantially vertically and downwardly.
- the intermediate member 30 is in the form of a U-shaped profile open on the outside of the vehicle which is intended to form a bearing abutment to an adjacent wheel in the event of a frontal impact of the vehicle against an obstacle.
- the intermediate member 30 comprises a base 31 from which extend substantially longitudinally to the vehicle, an inner leg 32 and an outer leg 33. The inner leg 32 is fixed to the corresponding flange 28 of the connecting member 25 and the outer branch 33 is fixed on the front foot 9.
- the width of the intermediate member 30, more particularly the width of the base 31, varies to ensure the connection between the connecting member and the front foot.
