For the support of the plate element (10) there is provided an extension shaft (1) which at one end (2) is arranged to be secured to said shaft end, and at its other end (9) is arranged for fixed mounting of the plate element (10). A hub-protecting means comprises a cup-shaped member (6) having a bottom part including a tight bearing (4) for journalling of the extension shaft (1), and an inwards projecting sleeve member (5) for tight connection with the vehicle wheel around the bearing thereof.

Description: Non-rotating hub cap for a vehicle wheel The present invention relates to an arrange— ment in a vehicle wheel which is mounted on a bearing at the end of a fixed shaft, comprising a plate element covering a portion of the outer side of the wheel and being intended for the application of advertising text or the like, a support means for supporting and secu¬ ring the plate element in relation to the shaft end, and a hub protecting means attached to the wheel in¬ side of the plate element. There are previously known various types of devices having non-rotating disks- which are attached to non-rotating shafts on the outer side of wheels on vehicles, especially on cars,, to display names, adver¬ tising texts or the like on the stationary disk while the vehicle is in motion. A device of the type stated above, i. e. a device having a rota-ting, hub-protecting means which is attached to the wheel inside of the stationary plate element, is known from US patent specification 3 795 997. Such a protecting means is a necessity in order to protec the wheel bearing against dust, mud and other detrimental influence, to prevent damage of the wheel bearing during operation. In the known device, however, the hub-pro¬ tecting sealing means is relatively complicated and has many parts, and the same is the case with the mounting for the plate element forming the hub cap. As a result of the several component parts, the known device will be correspondingly expensive in production. The object of the invention is to provide a devi of the introductorily stated type which secures a good protection of the wheel bearing and is of a simple and simultaneously reliable construction. According to the invention, the above-mentioned object is achieved in that the support means of the plate element comprises and extension shaft which at one end is arranged to be secured to said shaft end, and at its other end is arranged for fixed mounting of the plate element, and that the protecting means is a cup-shaped member having a bottom part including a tight bearing for joumalling of the extension shaft, and an inwards projecting sleeve member for tight connection with the vehicle wheel around the bearing thereof. A simple and advantageous embodiment of the invention is characterized in that said one end of the extension shaft has a screw thread for threading onto a corresponding thread on the shaft end, and that the other end is formed, for screwing-on of a nut member " for securing of the plate element, this having a central aperture to be placed on said other end of the extension shaft. The invention will be- furthe-r described below with reference to the accompanying drawings, wherein Fig. 1 shows an axial, partly sectioned view of a first embodiment of an arrangement according to the invention; Fig. 2 shows a side view of the extension shaft in the arrangement of Fig. 1; Fig. 3 shows a view in the direction of the arrow A in Fig. 1; Fig. 4 shows an axial, partly sectioned view of a scond embodiment of an ' arrangement according to the invention; Fig. 5 shows a side view of the extension shaft in the arrangement of Fig. 4; Fig. 6 shows a section along the line VI - VI in Fig. 4; and Fig. 7 shows an end view of the extension shaft in the direction of the arrow B in Fig. 4_- The embodiment of the arrangement according to the invention shown in Figs. 1 - 3 comprises an exten¬ sion shaft 1 which at one end thereof is formed with a sleeve-shaped nut member 2 having a hexagonal outline- as shown in Fig. 3, and having an inner thread 3 for screwing onto a corresponding outer thread on the end of a fixed (i. e. non-driven, wheel shaft (not shown, on a vehicle. At the central portion of the extension shaft 1 there is placed a tight bearing 4 which is shown in the form of a ball bearing and is pressed into one end of a sleeve 5 extending inwards towards the vehicle wheel (not shown) and being arranged for connection with the wheel around the bearing thereof. Thus, the sleeve 5 and the bearing 4 form a cup-shaped member 6 which pro¬ vides for a tight protection of the wheel bearing at the same time as the bearing 4 forms a supporting moun¬ ting for the extension shaft 1. The bearing 4 is kept in place by means of a locking ring 7 placed in an encircling groove 8 in the extension shaft 1. The other end 9 of the extension shaft 1 is arranged for fixed mounting of the hub-cap forming plate element 10 (only partly shown in Fig. 1) of the arrange¬ ment, and for this purpose is provided with a thread 11 for screwing-on of a nut 12. The plate element 10 has a central aperture 13 for introduction on the extension shaft, and is retained thereon between the locking ring 7 and a washer 14 placed between the plate element 10 and the nut 12. When assembling the arrangement according to th invention on a vehicle wheel on a fixed shaft, the tra¬ ditional cup protecting the wheel bearing is firstly re¬ moved, and further the original wheel nut is removed. The extension shaft 1 is thereafter attached to the whee shaft, so that the nut member 2 of the extension shaft replaces the wheel nut, and the inwards projecting sleeve member of the cup member 6 is attached to the wheel, so that this member replaces said protecting * cup. Thereafter the plate element 10 is attached to the extension shaft by means of the nut 12 and the washer 14. The embodiment shown in Figs 4 - 7 is intended for mounting on a hollow wheel shaft. Thus, one end 16 of the extension shaft 15 is provided with an outer thread 17 for screwing into a corresponding inner thread in the end of the hollow wheel shaft (not shown) . In other respects, the structure in principle corresponds to the embodiment according to Figs. 1 - 3, and corre¬ sponding parts are designated by the same reference nume¬ rals_ As appears * from Fig. 4, the cup member 18 in this embodiment is somewhat different from the embodiment de¬ scribed above, this member - in addition to the sleeve member 19 - having a bottom part 20 covering the bearing 4, the central aperture 21 of the bottom part having a diameter which is adapted to the diameter of the exten¬ sion shaft 15 in this region. At the end 22 of the extension shaft 15 located opposite to the thread 17, there is screwed on a threaded pin 23 for the reception of a nut 24 for clamping of the plate element 10 (only partly shown in Fig. 4) . This nut has an inwards projecting flange 25 which is adapted to project into the central aperture 13 of the plate element 10 to support the plate element which in this case is clamped between the washer 14 and the adjacent end of the extension shaft. From Fig. 7 it appears that the extension shaft 15 in the end region 22 is provided with diametri¬ cally opposite bevels 26 forming abutment surfaces for a wrench or the like when assembling or disassembling the extension shaft 15.
