Definitions

• Motor vehicle comprising a two-part rear floor and means for stiffening the front part
• the present invention relates to the field of motor vehicles and, in particular commercial vehicles having a single row of seats.
• the invention relates to the structure of the floors of the motor vehicle.
• Commercial vehicles comprise, at the rear of the first row of seats, delimiting a rear floor of a front floor, a loading space whose rear floor has an embossed pattern generally produced during stamping of the sheet forming the rear floor.
• an upper floor called “load stop floor” is arranged to cover the rear floor.
• the floor of a motor vehicle comprises a rear portion called “rear floor” connected to a front portion called “front floor” by a shoulder called “cloak se”.
• the rear floor thus defined is delimited by the crossbar clo se and a towing ring located at the rear end of the motor vehicle.
• a rear floor In order to simplify the design of a rear floor, it is intended to provide a two-part rear floor, comprising a front portion and a rear portion interconnected by connecting means so as to form a sheet.
• the upper floor will then be intended to cover the front portion of the rear floor, to form a substantially flat loading space.
• a fuel tank is located under the rear floor, so that a hatch or a hole defining an area called "gauge well" provides access to the fuel tank gauge.
• This access zone is in the form of a hole made in the front part of the rear floor.
• this access area In order to use the known rear floors in all types of vehicles, it is necessary to adapt this access area, especially for commercial vehicles. Indeed, in commercial vehicles, this access area is blocked by the presence of the upper floor on the front portion of the rear floor. In order to ensure the stiffness of the rear floor, the drilling must be plugged.
• An object of the invention is therefore to overcome these disadvantages and to provide a motor vehicle comprising a rear floor having sufficient stiffness, especially at the front portion of the rear floor, to stiffen the upper floor.
• the invention relates to a motor vehicle comprising a rear floor having a front portion and a rear portion connected by connecting means, a front floor connected to the front portion of the rear floor, an upper floor covering the front part of the rear floor and a fuel tank arranged under the rear floor.
• the rear floor comprises stiffening means of the front portion in contact with the upper floor.
• the front part of the rear floor comprises a first substantially flat portion of attachment to the part rearward and to the upper floor extending towards the front of the vehicle by two substantially inclined portions and by a second substantially flat portion of attachment to the upper floor, said substantially planar portions forming first and second contact surfaces.
• the second substantially inclined portion comprises a stamped portion defining a zone of access to the gauge of the fuel tank.
• the stamped portion may include a counter-stamped portion defining a third surface of contact with the upper floor.
• the upper floor is fixed to the counterpart of the article before the rear connection by means of welding.
• the front part of the rear floor comprises a transverse cross member.
• the upper floor may include a stiffening bracket opposite the cross member of the rear floor.
• FIG. 1 shows schematically a portion of a motor vehicle according to the invention
• Figure 2 is a side view of Figure 1.
• transverse axis Y horizontal, perpendicular to the X axis and directed from right to left of the vehicle moving forward;
• a part of a motor vehicle referenced 1 as a whole, comprises a rear floor 2 intended to be connected to a front floor (not shown) of the motor vehicle 1.
• the rear floor 2 extends along a longitudinal axis X, under the loading space, including a commercial vehicle, and above the axis of the rear wheels (not shown) of the vehicle.
• the rear floor 2 comprises a front portion 3 connected to the front floor (not shown) generally by a transverse cross member (not shown) and a rear portion 4 connected to the front portion 3.
• the rear portion 4 has a substantially planar plate shape extending in the XY plane, while the front portion 3 has a first substantially planar portion 3a extending in the extension of the rear portion 4 and two substantially inclined portions 3b , 3 c so as to form a vertical drop along the Z axis between the front part 3 and the rear part 4.
• the second substantially inclined portion 3 c extends towards the front of the motor vehicle 1 by a second substantially flat portion 3 d.
• the second flat portion 3 d is aligned with the first flat portion 3 a.
• the first flat portion 3a of the front portion 3 rests on a tongue 4a located at the front end of the rear portion 4.
• the front and rear parts 3, 4 are made of stamped sheet metal and are interconnected by means of welds forming a weld seam at the junction between the two parts 3, 4.
• the front and rear parts 3, 4 can be connected by gluing or other means of attachment.
• the motor vehicle 1 comprises an upper floor 5 intended to cover the front portion 3 of the rear floor 2 in order to obtain a substantially flat surface facilitating loading in the loading space of the motor vehicle 1.
• the upper floor 5 has a substantially planar plate shape extending in the XY plane in the prolongation of the rear portion 4 and is respectively fixed on each of substantially flat portions 3a, 3d of the front portion 3 of the rear floor 2, to form two contact surfaces (not referenced).
• the second substantially inclined portion 3c includes a stamped portion 6 defining a gauge access area of a fuel tank (not shown) located below the rear floor.
• the stamped portion 6 comprises a counter-stamped 7 delimiting a third contact surface (not referenced) with the upper floor 5.
• the upper floor 5 is attached to the counter-stamped 7 of the front portion 3 of the rear floor 2 by welding means 8, for example at two points of welding.
• the front portion 3 of the rear floor 2 comprises a transverse cross member 9 extending transversely with respect to the longitudinal axis X of the motor vehicle 1 and fixed on the lower surface of the second substantially inclined portion 3c.
• the upper floor 5 comprises a stiffening bracket 10 fixed on the lower surface of the upper floor 5 facing the transverse cross member 9 of the rear floor 2, so that during loading in the loading space, the upper floor 5 rests on three contact surfaces of the rear floor 2, respectively the two substantially planar portions 3a, 3d and counter-stamped 7, as well as on the stiffening bracket 10.
• counter-stamped 7 can reduce this zone Z I Z2 in a zone of smaller dimensions.
• such a counter-stamped 7 allows to use such a commercial vehicle rear floor for any other vehicle without significant changes. Indeed, for the use of such a floor for a non-utility vehicle, it will suffice to drill the counter-stamped 7 to allow free access to the fuel tank gauge.
