HUBCAP WITH FASTENING MEMBERS FOR MOUNTING IT TO A VEHICLE WHEEL AND TO THE RELATING HUB ASSEMBLY

Abstract: Hubcap (l) with fastening members (4) for mounting it to a vehicle wheel (2) and to the relating hub assembly, said fastening members being provided by cup shaped elements (4) forming a separate portion or portions in respect of the remaining part of the hubcap (l), the side wall (26) of an element (4,l4) being provided with at least one portion (9,33) which can cooperate with a portion (28,32) of the hubcap (l,3l) present at some distance from the bottom (24) of said cup shaped element (4). Each cup shaped element (4) separately or together with a central portion (l4) of the hubcap (l) being made from a temperature resistant plastic material.

Description: The invention relates to a hubcap with fastening members for mounting it to a vehicle wheel and to the relating hub assembly, said fastening members each comprising a cup shaped element the bottom of which is coming to lie near the wheel and is provided with an opening for receiving a stud or bolt by which the wheel is mounted to a hub assembly of the vehicle. Such a hubcap is known from the U.S.-A-4,457,560 and is used for the embellishment of cars, in particular private cars. Such a hubcap, generally speaking, is made by drawing a relatively thin plate of plastic such as e.g. impact resistant polystyrene. In case of said known hubcap use is made of an inner metal retention element secured to the outer plastic hubcap for mounting the hubcap to the hub assembly. So not only the plastic hubcap has to be manufactured, but also the metal part and the two parts have to be assembled. By this the known hubcap is relatively expensive. A further disadvantage being that said metal part is exposed to corrosion and that the plastic part of the hubcap lying against it can be heated to a relatively high temperature when the hubcap is mounted on a car driven with a high speed. When the plastic part of the hubcap is made of the above mentioned polystyrene this cannot withstand the high temperature. Further it can be pointed to U.S.-A-3,549,204 showing a hubcap not being provided with cup shaped portions but lying at some distance from the wheel which is pressed against the hub assembly. To prevent pressing of the hubcap towards the wheel over a too great distance around each opening through which a stud is passing, special shaped sleeve members are provided being made from a resilient material such as rubber or such like. This brings a rather complicated structure with it and further it is necessary to use special nuts for fastening the wheel and the hubcap to the hub assembly. The use of sleeve members of rubber can have disadvantages in view of the temperature of the hub assembly which can be rather high as already explained above. The object of the invention is to remove these disadvantages and to that end it provides a hubcap the cup shaped elements of which are forming a separate portion or portions in respect of the remaining part of the hubcap, the side wall of an element being provided with a portion which can cooperate with a portion of the hubcap present at some distance from the bottom of said cup shaped element. In this way it can be obtained that the loads exerted on the hubcap are taken up by the bolts or studs via the cup shaped elements. The cup shaped element, however, can be made sufficiently heavy to withstand these loads. Further said cup shaped elements can easily be manufactured, in particular from a temperature resistant plastic material. Because they are relatively small they can be manufactured at a low price. According to an embodiment of the invention it can be provided that the wall of the cup shaped element is conical widened from its bottom, the hubcap being provided with a corresponding portion adapted to said wall. In case of such an embodiment the load is exerted via the engaging conical portions. In addition to this or in case of a cylindrical cup wall the latter can be provided with a radial rim extending at least partially around the upper edge of said wall and engaging a matching rim forming part of said hubcap. It is obvious that by this a still better transmission of forces is obtained. A further advantage is that the material of the hubcap has to be drawn to a much lesser extent or nearly not at the position of the fastening members so that an excellent connection between the upper edge of the cup wall and the hubcap itself can be obtained. To obtain a more or less fixed connection between the cup shaped elements and the hubcap it can be provided that the radial rim of the cup wall is connected to the hubcap by means of a flat ring both sides of which being adhesive. It is, however, also possible to keep the radial rim of the cup wall pressed against the hubcap by means of a clamp ring shifted on the cup wall. To obtain a more easy connection and demounting of the cup shaped element and the hubcap it is also possibly to provide the cup wall with at least one outwardly extending cam which may snap behind the hubcap. A further possibility also is, that the hubcap and the cup shaped element are comprising means for obtaining a bayonet connection. According to a further embodiment of the invention it can be provided, that the cup shaped elements are integrally formed with the central portion of the hubcap and that the further ring shaped portion of the hubcap is fixed to the central portion. The advantage of this is, that the central portion can be shaped solid and that, if necessary, the further ring shaped portion of the hubcap can be replaced afterwards when this is damaged. The possibility of damage of this ring shaped portion is much greater than the possibility of damage of the central portion. For further embellishment it can be provided that the cup shaped elements are closed by a lid. In that case the nuts or bolts are completely hidden from view. The cup shaped elements either in combination with the central portion of the hubcap or not, in particular can be manufactured by injection moulding from a temperature resistant plastic so that these parts or this part can have a considerable strength. Other objects and advantages of the present invention will become apparent from the description of embodiments shown in the drawing, in which: Fig. l is showing a view of a vehicle wheel with a hubcap according to the invention mounted on it; Fig. 2 is showing a cross-sectional view over a portion of the wheel along the line II-II of Fig. l, in which a given way of connection is used of the cup shaped elements to the hubcap; Fig. 3 is showing a cross-sectional view of a cup shaped element with the related portion of the hubcap to show two different ways of connection of the cup shaped element to the hubcap; Fig. 4 is showing a cross-sectional view of a cup shaped element and the related portion of the hubcap the connection between these both parts being obtained in a still other way; Fig. 5 is showing a plan view of the cup shaped element of Fig. 4; Fig. 6 is showing a cross-sectional view of a cup shaped element with the related portion of the hubcap, for the connection of both parts use being made of a bayonet connection; Fig. 7 is showing a plan view of the cup shaped element of Fig. 6; and Fig. 8 is showing a cross-sectional view of a hubcap, the central portion of which is integrally formed with the cup shaped elements. In the embodiment shown in the Figs.l and 2 the hubcap l is mounted on a wheel 2 on which a tire 3 is present. The hubcap l is provided with a number of cup shaped elements 4, the bottom 24 of which is provided with an opening 25 for receiving the wheel bolt 5, so that the head of this is pressing the bottom of the cup shaped element against the wheel. It is obvious that also an outwardly extending stud can be present on which a nut is screwed. The hubcap l can be provided with decorations such as in the shape of openings 6 and cutter shaped impressed portions 7. In particular from Fig. 2 it appears that the hubcap l is engaging the wheel rim 8 and is fixed by means of the cup shaped elements 4. Fig. 3 is showing, at an enlarged scale, a cup shaped element 4 which is mounted to the hubcap l. In the left part of Fig. 3 it is shown that the mounting of the cup shaped element 4 to the hubcap l can take place because the rim 9 of the element 4 is pressed against the hubcap l by means of a ring l0 which is shoved onto the cup shaped element 4 and is clamped thereon, said element preferably having a somewhat conical side wall 26. It will be obvious that the conical side wall can be provided with a somewhat depressed portion for obtaining a solid fastening of the ring l0. In the right portion of Fig. 3 it is shown that the rim 9 of the cup shaped element 4 can be connected to the hubcap l by means of a ring ll both sides of which being adhesive. The Figs. 4 and 5 are showing the possibility that the side wall 26 of the cup shaped element 4 is provided with three tapered cams l2, so that the cup shaped element 4 can be received in the opening 27 of the hubcap l during which the rim 28 of the hubcap will snap over the cams l2 by which a solid connection between the hubcap l and the cup shaped element 4 can be obtained. The Figs. 6 and 7 are showing the possibility to use a bayonet connection between the hubcap l and the cup shaped element 4, to which end the wall 26 of the element 4 again is provided with cams l3 and the rim 28 of the hubcap l with recessions 29 through which the cams l3 can pass whereafter by rotation of the cup shaped element 4 in respect of the hubcap l the cup shaped element can be fixedly clamped. Finally Fig. 8 is showing the possibility to execute the cup shaped elements 4 integral with the central portion l4 of the hubcap l, said hubcap further consisting of the annular portion 3l, the inner rim 32 of which is pressed against the circumferential rim 33 of the central portion l4 e.g. by means of the ring l5 about in the same way as described for the ring l0 in case of the embodiment according to Fig. 3. It will be obvious that the ring l5 is engaging the cup shaped element 4 only with a small part of its inner circumference. Again use can be made of an adhesive ring, as indicated in Fig. 3, or of snapping portions as indicated in Fig. 4 or of a bayonet connection as indicated in the Figs. 6 and 7. It will be obvious that in the Figures only some embodiments are shown which are described above and that many modifications can be applied without leaving the scope of the invention.
