Definitions
- the field of the invention is that of the automotive industry. More specifically, the invention relates to cradles supporting motor vehicle engines or rear trains.
- engine cradles comprise two shells made of pressed sheet metal and assembled together, for example by welding.
- One of the functions of these cradles is to withstand the forces generated by the engine torque during acceleration or deceleration phases of the vehicle.
- a cradle otherwise known as a "mini cradle” by a person skilled in the art, is secured to the vehicle body in the rear part and, in the front part, to a shock absorber. shocks 2 or “add-on” fixed on the plates 13 of the cradle.
- such a cradle is coupled to lower arms 3 wheel carriers or carrying wheel support means 31 (shown symbolically), an anti-roll bar 32 connecting these arms and being held on the cradle.
- the securing of the cradle to the vehicle body is carried out on an assembly line in the following manner.
- the assembled and painted box arrives on the assembly line, fixed on a "swing", located in height relative to the ground.
- the cradle In parallel, the cradle is pre-positioned by an operator on a so-called TMA platen (automatic mounting plate), mobile essentially vertically (the possibilities of displacement of these plates in the horizontal plane are limited to a few millimeters).
- TMA platen automated mounting plate
- the swing that supports the body then advances to position itself above the deck.
- This which also supports all elements mounted on the body (running gear, engine, exhaust, pipe ...), mounted vertically to dock all the elements with the box.
- the cradle is equipped with recentering means that compensate for any geometrical defects between the body and the cradle fixings, this acting on the position of the plate in the horizontal plane.
- the cradle is then screwed onto the body, nuts having been welded to the body prior to the assembly phase.
- the refocusing means mentioned above are constituted by a piece in the form of a spacer which is either integral with the cradle, or an integral part of the elastic filtering articulation.
- This spacer engages in a recess of the box, this end having a conical shape intended to ensure the centering of Pentretoise relative to the recess of the box.
- the spacer therefore has a specific shape for centering on the vehicle by lodging in the box.
- the specific form of the spacer has the function of making a catching of any misalignment between the cradle and the body.
- the centering function of the spacer is made using a conical shape, this cone having the advantage of finishing in a point, which minimizes the risk that the cone comes to rest under the body at moment of the vertical displacement of the plate, which would cause the lifting of the body rather than the engagement of the cone in the corresponding orifice thereof.
- the tip of the cone is brought, at worst, in the orifice limit (inside thereof) and the surface of the cone forms a sliding surface for the body as the engagement of the cone in the opening of the body.
- This step of machining the cone has several disadvantages.
- machining step and in particular a step of machining a cone, substantially increases the cost of the part, which is obviously not desirable.
- the invention therefore particularly aims to overcome the disadvantages of the prior art.
- the invention aims to provide a positioning part of a cradle relative to the body of a vehicle that allows to consider logistical gains between the beginning and the end of the manufacture of the piece.
- the invention also aims to provide such a positioning piece that can be obtained less costly than traditional positioning parts.
- the invention also aims to provide such a positioning piece which is simple in design and easy to implement;
- a positioning piece intended to be carried by a cradle and to be engaged in a recess of a motor vehicle body , of the type having a body forming a spacer between two shells of said cradle, said body having at least one peripheral element forming a bearing surface with a wall of a shell of the cradle intended to take place in the vicinity of said box, said piece of positioning comprising a portion with decreasing section at its end intended to be engaged in said recess of said box, characterized in that said portion has, in a longitudinal section, a curved shape capable of to be made by creep material, said peripheral element is also obtained by creep material.
- a positioning piece according to the invention can be shaped using a single manufacturing technique consisting of proceeding by creep material, for example by forging. It is therefore not necessary to organize the logistics of the parts between the forging stations and machining as was the case in the prior art.
- the invention eliminates the machining step of the prior art which was a significant part of the cost of manufacturing parts.
- said curved shape is defined, in longitudinal section, by at least two circular arcs, one said proximal to the vicinity of said end intended to be engaged in said recess of said box, the other said distal in extending said proximal arc and extending to said peripheral member.
- the radius of curvature of said distal arc is between 75% and 100% of the largest diameter of said portion.
- said curved shape is defined, in longitudinal section, by at least two circular arcs, one said proximal to the vicinity of said end intended to be engaged in said recess of said box, the other said distal in the extension of said proximal arc and extending to said peripheral member, said proximal arch having a radius of curvature of between about 1 mm and about 4 mm, said distal arc (432) having a radius of curvature of between about 15 mm and about 25 mm .
- a curved shape composed of two arcs each having a specific function.
- the arches are "marked” by their function by providing a ratio of about 20 between the radius of curvature of the proximal arch and that of the distal arch.
- the curved shape is divided into two portions: one essentially intended to facilitate the filling of the tool during creep material, and the other essentially to form a sliding surface, possibly very sloping.
- Such a curved shape indeed has a very satisfactory compromise between its ability to be obtained by forging (or other material creep technique) and its ability to promote the sliding of the body on the positioning part.
- a very sloping shape greatly favors sliding but becomes difficult if not impossible to obtain by creep material (a conical shape according to the prior art can not be obtained by forging, the material failing to fill the tooling ), while a too crushed shape is obtained very easily by forging but tends to constitute a bearing surface (able to raise the body) rather than a sliding surface.
- said proximal arch preferably has a radius of curvature of about 1 mm, said distal arc having a radius of curvature of about 20 mm.
- the positioning piece is made of steel.
- said portion extends in the direction of said peripheral element by a cylindrical portion having a thickness of about 7 mm.
- Such a thickness makes it possible to constitute a sufficiently large quantity of material to carry out the creep operation, while limiting the weight of the part.
- said spacer body is inserted into a socket, an elastic material being provided between said body and said socket so that said part forms a filter pad.
- the invention also relates to a cradle comprising at least two shells between which at least partially extends a positioning piece intended to be engaged in a recess of a crate of motor vehicle, said part having a body forming a spacer between said shells and having at least one peripheral element forming a bearing surface with a wall of one of said shells intended to take place in the vicinity of said box, said positioning piece comprising a portion with decreasing section at one end intended to be engaged in said recess of said box, characterized in that said portion has, in a longitudinal section, a curved shape capable of being produced by creep material, said peripheral element being also obtained by material creep.
- the invention also relates to a motor vehicle equipped with a cradle comprising at least two shells between which at least partially extends a positioning piece intended to be engaged in a recess of a body of said vehicle, said part having a body forming spacer between said shells and having at least one peripheral element forming a bearing surface with a wall of one of said shells intended to take place in the vicinity of said box, characterized in that said portion has, in a longitudinal section, a shape curved which can be made by creep material, said peripheral element is also obtained by creep material.
- FIG. 1 is a perspective view of a cradle of a motor vehicle in its immediate environment
- FIGS. 2 and 3 are views respectively in perspective and in longitudinal section of a positioning member according to the invention.
- the principle of the invention lies in the fact of designing a positioning part of a cradle relative to the body of a vehicle so that this part can be achieved by a material creep technique, in particular as regards the curved shape of its end intended to be engaged in an orifice of the vehicle body.
- FIGS. 2 to 4 show a positioning piece 4 having a body 41 intended to form a spacer between two shells 11, 12 of a motor vehicle cradle, this body 41 having a peripheral element 42 constituting a surface of support intended to be pressed against the inner wall of the upper shell 11 (that is to say the shell placed in the vicinity of the body once the cradle mounted).
- the end of the positioning piece 4 intended to be engaged in the body has a curved shape 43 capable of being produced by material creep, the peripheral element 42 being also produced by creep of material.
- FIG. 3 shows a positioning piece of which a peripheral element 42 bears on a shell 11 of the cradle and whose curved end 43 penetrates an orifice 51 of the body 5.
- the positioning piece according to the invention is integrally shaped by a material creep technique, and in this case by forging.
- the curved shape 43 is defined in longitudinal section, as illustrated in FIG. 5, by two successive arcs of circles: a so-called proximal circular arc 431 whose radius of curvature R1 is approximately 1 mm, and a distal arc 432 whose radius of curvature R2 is about 20 mm.
- a so-called proximal circular arc 431 whose radius of curvature R1 is approximately 1 mm
- a distal arc 432 whose radius of curvature R2 is about 20 mm.
- the curved shape 43 extends in the direction of the peripheral element 42 by a cylindrical portion having a thickness e equal to 7 mm.
- the positioning piece 4 is made in the form of a filtering pad (not shown), the body 41 being surrounded by a sleeve, an elastic material such as the rubber being inserted between the body of the piece and the socket.
- the peripheral element can take place on the outer wall of the upper shell, being then welded to it.
