Definitions
- the present invention relates to a front structure of a motor vehicle located between the engine compartment of the vehicle and the passenger compartment.
- Motor vehicles usually include a body having a floor and towards the front, an apron erected transversely on the floor.
- the body has on each side, a front leg extending vertically by a lateral upright on which the door hinges are usually anchored.
- the apron extends transversely over the entire width of the body approximately to the right of the two uprights.
- motor vehicles include a dashboard crosspiece, which extends along the apron and whose two opposite ends are respectively also anchored on the two uprights.
- the dashboard crosspiece is generally made of a metal tube forming a beam and having at each of its ends a flange allowing it to be connected to the uprights, for example by means of screwable fixing members.
- the steering column support and the inflatable safety bag supports are usually connected to this dashboard crossmember.
- the dashboard crosspiece is sufficiently rigid to accommodate these elements without it being deformed when they are stressed. It must in fact take up the forces exerted on the steering wheel to guide the vehicle. It must also resume efforts to deploy the airbag. In addition, it must support the heating, ventilation and air conditioning system commonly known by the acronym: “HVAC”, for: “hight, ventilation an air-conditioning” in English.
- HVAC heating, ventilation and air conditioning system commonly known by the acronym: “HVAC”, for: “hight, ventilation an air-conditioning” in English.
- a problem which arises and which the present invention aims to solve is to provide a lighter front structure of a motor vehicle at an advantageous cost.
- a front structure of a motor vehicle comprising: a floor and an apron erected on said floor, said apron extending transversely between two side uprights; a dashboard crosspiece having two opposite ends and extending along said apron to be able to receive a steering column support and an airbag support.
- Said dashboard crosspiece is integral with said apron, and said two opposite ends extend freely respectively at a distance from said two side uprights.
- a characteristic of the invention lies in the implementation of a shorter dashboard crosspiece, and therefore less heavy, and which nevertheless makes it possible to support, at the very least, the steering column and the support airbag.
- the weight of the dashboard crosspiece is significantly reduced, and therefore, to a certain extent, the weight of the motor vehicle in which it is installed.
- said steering column support is connected to one of said two ends of said dashboard crossmember, while said airbag support is installed on the other of said two ends.
- the length of the dashboard crossmember is reduced to its minimum so that the steering column can extend to the right of the driver's seat, while the airbag support extends to the right of the seat passenger.
- said dashboard crosspiece has a middle part, and advantageously, said middle part is secured to said apron. So the apron which is a rigid element of the body of the motor vehicle, makes it possible to maintain the dashboard crossmember in a fixed position also in a rigid manner.
- said two opposite ends of said crosspiece extend freely respectively equidistant from said two lateral uprights.
- the dashboard crosspiece is centered between the two uprights and consequently, its middle part comes in line with the middle part of the vehicle body.
- said jamb comprises two substantially parallel arcuate legs connected together by a crosspiece.
- the two arcuate legs extend from the apron towards the floor, gradually moving away from the apron. They are held in a fixed position relative to each other thanks to the crosspiece.
- said two arcuate legs are curved in parallel planes, normal to said apron.
- said dashboard crosspiece is tubular.
- the crosspiece is of circular section, which provides good resistance to deformation in relation to the quantity of material used.
- FIG. 1 is a partial schematic perspective view of a front structure of a motor vehicle according to the invention.
- FIG. 2 is a detailed schematic view of [Fig. 1 ] according to arrow II.
- FIG. 1 shows in perspective, and partially, a front of the passenger compartment 10 of a motor vehicle according to the invention.
- the front of the passenger compartment 10 comprises a floor 12 at the end of which stands an apron 14, in an average plane substantially parallel to the plane (Y, Z).
- the apron 14 has an upper edge 15. Also, the apron 14 delimits an engine compartment 16 from the front part of the passenger compartment 10.
- the floor 12 here includes a median tunnel 18 making it possible to route different pipes between the front and the rear of the motor vehicle.
- the median tunnel 18 extends longitudinally in the center of the floor 12 in direction X.
- the apron 14 extends transversely in the direction Y between two opposite uprights, a left upright 20 and a right upright 22, shown here partially.
- the front structure of a motor vehicle shown in [Fig. 1 ] comprises a dashboard crosspiece 24 held transversely along the apron 14 via a leg 26.
- the jamb comprises two arcuate legs, a left leg 28 and a right leg 30, which are substantially parallel and connected together by a crosspiece 32.
- the two arcuate legs 28, 30 are formed from steel and the crosspiece 32 itself steel is welded to connect them together.
- the fixing foot 34 consists of a bracket having two wings allowing it to be applied perfectly on the edge of the edges of the tunnel 18. Also, the bracket is then made integral with the tunnel 18 by means of two fixing screws, one through each wing.
- the fixing plates 36 have two holes allowing two other fixing screws to be inserted and screwed through the apron 14.
- the two arcuate legs 28, 30 define two substantially parallel mean planes between and which are substantially normal to the apron 14.
- the crosspiece 32 which connects the two legs 28, 30, it extends substantially perpendicular to them and substantially equidistant from the fixing plate 36 and the fixing feet 34.
- the dashboard crossmember 24 is then connected, in a middle part 35 thereof, to the upper ends of the two legs 28, 30, near the fixing plates 36 to be held in a fixed position in the transverse direction Y along of the upper edge 15 of the apron 14.
- the dashboard crosspiece 24 is tubular and preferably of circular section. Its section is not necessarily of constant dimension over its entire length. Also, it is made of steel, so that it can be connected to the two arc legs 28, 30 by welding. Preferably, it is welded inside the curvature of the two arcuate legs 28, 30, so as to improve the rigidity of the fixing.
- the dashboard crosspiece 24 has two opposite ends, a left end 38 and a right end 40, which ends are located respectively, substantially equidistant from the left 20 and right 22 uprights.
- the dashboard crosspiece 24 is substantially centered along the transverse component Y with respect to the apron 15 and the two arcuate legs 28, 30.
- its left end 38 is connected to a steering column support 42.
- the support steering column 42 extends obliquely and projects from the apron 14, it should be kept in a fixed position in this orientation.
- the steering column support 42 thus accommodates the steering column, not shown, and which extends from the engine compartment 16 into the passenger compartment, through the apron 14.
- the steering column support 42 is T-welded to the left end 38 of the dashboard crossmember 24 as illustrated more precisely in [Fig. 2],
- the left end 38 of the crosspiece 24 is machined in a “wolf's mouth” shape to be able to fit against the cylindrical external wall of the steering column support 42 and to be welded there at the joint 44 of the two elements.
- the steering column support 42 is made of steel to be able to carry out this welding.
- the dashboard crossmember 24 has a minimum length allowing it to fulfill its essential functions of support, steering column support 42 on the one hand, and airbag support 46 on the other hand. In this way, its weight is less compared to a crosspiece which would extend from the left upright 20 to the right upright 22.
- dashboard crosspiece 24 can also receive the supports for the heating, ventilation and air conditioning device.
