Definitions

  • the invention relates to a device for closing a oil filling hole.
  • the invention relates, more particularly to a device shutter of an engine oil filling orifice, a gearbox, or a vehicle differential automobile, of the type in which the upper free end of a frustoconical cylindrical filling orifice receives a cap which carries an annular seal and which has two diametrically opposite lugs which penetrate axially in associated radial recesses of the orifice tapered cylindrical and which, when tightening in rotation, cooperate respectively with two inclined ramps and peripherals carried by a lower transverse face of the cylindrical orifice, to allow locking, of the type to bayonet, plug in closed position.
  • provisions constructive linked to the area to be sealed such as example the installation of a special plug forming an oil breather, or aesthetic considerations, such as the integration of an engine oil filler cap into a housing style, such as a particular cylinder head cover associated vehicle, may require positioning precise angle of the cap.
  • the plug must also be able to be an element of a mechanism common to several automotive partners and be easily identifiable stylistically, for example using a hubcap specific.
  • the present invention provides a device of the type described above, characterized in that the cylindrical orifice has a partition transverse annular provided with polarizing means of the angular position of insertion of the plug, and the face of which bottom has two clamping ramps, which protect the seal area of the direct oil splash seal.
  • the device 10 includes a filling orifice 12 comprising a transverse annular partition 14 which receives a plug 16 which is for example made molded of material plastic, and enters the filling orifice 12 through its central hole 17.
  • the plug 16 comprises, in its lower part of small diameter 28, two locking and retaining lugs 18 and 19 diametrically opposed ones that are designed to be respectively received by radial recesses 20 and 21 of the transverse partition 14 of the filling orifice 12.
  • the body of the plug 16 of the filling orifice 12 has a handling tab 22 substantially triangular which receives a hubcap 24 which is for example made of plastic material.
  • the cap cover 24 has in its part upper a manipulation tab 26 of shape substantially parallelepipedic and allowing a easy handling of the assembly consisting of the hubcap 24 and of the filling port plug 16.
  • the obturation of the orifice of filling 12 by assembling the filling plug 16 and its hubcap 24 is particularly advantageous because it allows to dissociate the mechanical functions of closing the filling orifice 12 of any aesthetic functions.
  • the filling plug 16 provides mechanical locking, sealing functions and indexing, while the hubcap 24 performs the function of grip and plays an aesthetic role.
  • FIG. 2 illustrates in detail the mounting of the plug filling 16 in the filling orifice 12.
  • the annular partition 14 allows passage through its circular central hole 17 of a cylindrical lower part 28 of small diameter of the body of the filling plug 16, which carries the radial locking and retaining lugs 18 and 19 whose upper facets are designed to cooperate with two peripheral ramps 30 carried by one face lower 13 of the transverse annular partition 14.
  • the filling orifice 12 is here constituted by a upper free end section of a tubular pipe frustoconical filling including an upper part 32 has a chamfer 34 opening into the annular face of a free upper end 35 of the filling orifice 12 and allowing the introduction of a central part 36 of the filler cap 16.
  • the cylindrical central part 36 has a radial groove 38 which receives an O-ring 40 radial sealing.
  • O-ring made of elastomeric material 40 is compressed radially between the convex cylindrical bottom of the groove 38 of the filling plug 16 and a bearing concave frustoconical 42 inside the filling orifice 12 and opening into its upper part 32.
  • the axial distance between the face lower transverse 44 which delimits the central parts 36 and lower 28 of the plug 16 and the retaining pins and locking 18 and 19 is such that a functional clearance J remains between the transverse face 44 and the upper face 23 of the annular bulkhead 14.
  • This J game has the function of allowing the setting axial compression of the O-ring 40, which has on the one hand a sealing function and, on the other hand, a spring role of tightening in a substantially corresponding axial direction to the general axis of the filling orifice 12.
  • FIG. 3 illustrates the shapes of the transverse annular partition 14 of the filling orifice 12.
  • the annular partition transverse 14 has two radial recesses 20 and 21, asymmetrical and diametrically opposite, which receive respectively the locking and retaining lugs 18 and 19 of the filling plug 16 in order to ensure in particular a polarization of the angular orientation of the plug 16 with a view to its axial introduction into the filling orifice 12.
  • the transverse annular partition 14 comprises by elsewhere, at the end of one of the ramps 30, a stop 50 allowing the filling plug 16 to stop rotating after a quarter turn when lug 19 comes to rest angular against this stop.
  • the transverse annular partition 14 is particularly advantageous insofar as it simultaneously performs four functions, including one angular keying function of the filler cap 16, a tightening and locking function of the type bayonet of the filling plug 16 thanks to the ramps 30, but also a screen function with oil splashes on the contact area of the seal 40, and finally a stop function in rotation of the filling plug 16 in a position angular determined by the stop 50.
  • FIG. 4 illustrates the ramps 30 making it possible to produce tightening the plug 16.
  • the ramps 30 have on their lower faces which cooperate in axial support with the radial lugs 18 and 19 of the plug 16 of the peripheral inclined planes 52 which guide the movement of the plug 16 in rotation on the one hand and following an axial direction down on the other hand.
  • Each ramp 30 comprises, at the lower end of the inclined planes 52, a projection 54 which makes it possible to achieve a hard point when rotating the filler cap 16 when the pins 18 and 19 of the filling plug 16 arrive at the end of the angular locking stroke and cross these growths.
  • the outgrowths 54 allow to materialize for the user the effective tightening of the filling plug 16 by the feeling of the increase in the tightening torque to be supplied.
  • the ramps 30 each have a plate 55 whose dimension determines with precision the final axial position of the plug 16 in position tight and thus the vertical position of the seal 40 on its span 42.
  • one of the plates 55 is delimited angularly by the stop 50 at the end of the stroke.
  • FIG. 5 illustrates the mounting of the hubcap 24 on the filling plug 16.
  • the filling plug 24 is fitted elastically on a external radial flange 58 of the upper part 15 of the filling plug 16.
  • the collar 58 cooperates with a complementary internal radial rib 56 of the hubcap 24 formed at the lower end edge of a cylindrical skirt 57 of the latter which deforms radially for mounting by elastic fitting.
  • the leg of handling 22 of plug 16 is received in a housing complementary 25 to the hubcap.
  • the hubcap 24 being made of plastic material, its rigidity is ensured by support at two ribs internal 60, which extend in two parallel planes perpendiculars located symmetrically on either side of the plane of symmetry of the manipulation tab 22 of the plug 16.
  • the internal ribs 60 are in contact with the tab of handling the filler cap 16.
  • the angular position of the hubcap 24 by relative to the filling plug 16 is defined by a unequivocal and precise, on the one hand in the direction perpendicular to the plane of symmetry of the leg manipulation 22 by the interlocking of the ribs 60 on the tab manipulation 22, and on the other hand, by the complementarity of shape between a housing 25 of the hubcap 24 and the shape triangular of the manipulation tab 22 of the plug filling 16, which can be seen in Figure 2.
  • This arrangement is particularly advantageous because the filling plug 16 being, in the closed position, indexed unequivocally with respect to the filling orifice 12, the hubcap 24 can therefore only take an angular position unique with respect to the filling orifice 12, which allows integrate the hubcap 24 in a style according to its environment.
  • the transverse partition 14 previously mentioned may consist of two half-rings extending radially inside the orifice of filling 12 previously mentioned, ensuring the same functions, and arranged so that the radial recesses asymmetrical 20,21 consist of free spaces between these two half rings and extend to the wall internal of the filling orifice 12 previously mentioned.
  • the plug 16 may, as a variant, have in its upper part 15 a hollow imprint, coming in place of the manipulation tab 22 previously mentioned, which includes positioning means angular on the cap of the hubcap 24 previously mentioned, for example using a female cylindrical seat in which a complementary male cylindrical bearing of the plug is received and fitted tight when the cap, the preferential orientation of the hubcap relative to to the environment being obtained during manufacture by the assembly of the hubcap on the plug in a position determined.
  • This arrangement is particularly advantageous because it allows a large variety to be fitted onto the cap hubcaps each responding to a particular style. Employment a cap common to all hubcaps is a cost guarantee reduced manufacturing. In addition, these may present manipulation legs in various shapes and colors, extending for example radially along a greater radius to that of the filling orifice to facilitate their gripping like a lever.
