Definitions

  • the present invention relates to an arrangement for vehicle wheel bearings in accordance with the preamble of the accompanying patent claim 1.
  • the invention is particularly intended for integration of that type of wheel bearing, which includes an exterior ring intended for mounting in a carrier of a wheel bearing housing of the vehicle in question.
  • the individual wheel of a passenger car is commonly fitted rotatably on its wheel axle by means of a wheel bearing (e.g. in the form of a ball bearing), which in turn comprises an exterior ring that is fixedly attached to the vehi- cle.
  • a wheel bearing e.g. in the form of a ball bearing
  • This attachment of the exterior ring is made according to known technique by the exterior ring being shaped with a radially extending flange being provided with a multitude, for example four, of radially located holes.
  • the flange can be bolted, by means of four fastening bolts, to a particularly shaped wheel bearing carrier of the vehicle wheel bearing housing.
  • the inner ring of the above discussed wheel bearing is fitted onto a hub carrier.
  • This hub carrier includes on the one hand a sleeve-shaped part and on the other a radial flange, the actual hub of the subject wheel being arranged to be fitted on the radial flange.
  • the sleeve- shaped part is pushed onto a stub axle, which will then extend along the interior of the sleeve-shaped part.
  • a number of openings are arranged in the flange of the hub carrier, with the aid of which the wheel hub can be fastened by a corresponding number of wheel bolts. In this manner, the wheel can be fitted, together with its wheel bearing, into the wheel bearing carrier.
  • the object of the present invention is to provide an improved arrangement for a vehicle wheel bearing, which will in particular allow a wheel bearing installation where the above drawbacks are eliminated. This object is achieved by an arrangement, the characteristics of which will be disclosed in the accompanying claim 1.
  • the invention is intended to be used for a vehicle wheel bearing comprising an inner ring connected to a stub axle of the vehicle, arranged for carrying a wheel hub, and an exterior ring arranged for fixed mounting in a wheel bearing carrier of the vehicle.
  • the invention is characterised by comprising a sleeve element provided between the exterior ring and the wheel bearing carrier, and means for locking the sleeve element against axial movement relative to the exterior ring and the wheel bearing carrier.
  • the radial flange of the exterior ring can be made smaller than in known arrangements. Neither does this flange require any drilled through bolt holes.
  • a simpler assembly of the wheel bearing is obtained, as it does not have to be fastened by a number of bolts in the wheel bearing housing of the vehicle in question.
  • a snap-fastening arrangement is provided, where the exterior ring is initially provided with the sleeve element according to the invention, whereupon the complete wheel bearing assembly can be pushed into the wheel bearing carrier and then be snap-fastened. This provides for very easy and quick assembly of the arrangement according to the invention.
  • Another advantage of the invention is that it requires less space for installation in the vehicle in question than the known arrangement. Furthermore, according to the invention, a high degree of reliability is provided, as it does not require any screwed connection for securing the wheel bearing, which screwed connection might otherwise stand a risk of coming loose.
  • the above discussed sleeve element is manufactured from an electrically insulating material, e.g. polyamide.
  • an electrically insulating material e.g. polyamide.
  • the sleeve element can, due to its resilience, absorb any expansion of materials such as magnesium and aluminium, which may be used in connection with lightweight vehicles.
  • the invention provides for a lower total weight of the vehicle, as the exterior ring can be designed with a smaller radial flange and as there is also no need for any fastening bolts.
  • Fig. 1 is a cross sectional view, schematically showing an arrangement for a vehicle wheel bearing in accordance with the present invention
  • Fig. 2 is a perspective view showing a sleeve element and a retainer ring that can be used according to the invention
  • Fig. 3a is a partial cross section showing a portion of a second embodiment of the invention.
  • Fig. 3b is a further partial cross section showing a portion of said second embodiment, but taken at another position along the circumference of the sleeve element, and
  • Fig. 4 is a perspective view of a part of the sleeve element according to the second embodiment.
  • Fig. 1 shows the construction, in principle, of the present invention.
  • the invention comprises an arrangement for a wheel bearing intended for installation in connection with a wheel hub 1 of a motor vehicle, e.g. a passenger car.
  • the wheel hub 1 therefore comprises, in a conventional manner, a stub axle 2, extending along a through axle of rotation 3.
  • a hub carrier 4 On the stub axle 2, there is arranged, in a conventional manner, a hub carrier 4, which in turn is formed with a substantially sleeve-shaped part 5 extending concentrically around the axle 3, and with a flange 6 extending in a radial direction from said axle 3.
  • the flange 6 is provided with a multitude of radially located, through holes 7 (of which only one is visible in Fig. 1). Each hole 7 is intended for a through bolt 8, which together with a corresponding nut 9 is used for securing a wheel hub 10, belonging to the wheel intended to be fitted onto the hub 1 in question.
  • a brake disc (not shown) (or alternatively, a brake drum) in connection with the hub 1.
  • a brake disc would then be part of a disc brake assembly for braking the wheel in question.
  • the brake disc would preferably be located so as to be joined with the hub carrier 4 flange 6, preferably by the brake disc being clamped between the wheel hub 10 and the flange 6.
  • the invention can be utilised in such cases where the stub axle 2 consists of a driven or a non-driven wheel axle. According to the figure, the stub axle 2 is a driven axle, for which reason it is connected to the hub carrier 4 by a spline connection 11.
  • the hub carrier 4 is arranged to be rotatably fitted onto the stub axle 2 by means of a wheel bearing 12.
  • the wheel bearing 12 consists of a ball bearing, comprising, in a conventional manner, a number of bearing balls 13 arranged along two bearing races 14, 15 in the wheel bearing 12.
  • the wheel bearing 12 further comprises an exterior ring 16, arranged around the bearing balls 13.
  • the outer race 14, i.e. the race located closest to the wheel hub 10, is defined by an appropriately shaped section of the hub carrier 4, while the inner race 15 is defined by a separate inner ring 17.
  • the bearing balls When assembling the wheel bearing 12, the bearing balls are first fitted in the outer race 14 and the inner race 15, between the exterior ring 16 and the hub carrier 4, and the exterior ring 16 and the inner ring 17, respectively. Subsequently, the balls are secured inside the races 14, 15 by riveting of a principally annular end portion 18 of the hub carrier 4, causing the end portion 18 to be deformed and bent over the inner ring 17 so as to lock it on the hub carrier 4.
  • the exterior ring 16 supports an elastic, generally sleevelike element 19, which is intended for fastening of the wheel bearing 12.
  • the fastening of the wheel bearing 12 is achieved by a separate wheel bearing carrier 20, which in turn is fixedly arranged in the wheel bearing housing of the vehicle in ques- tion.
  • the sleeve element 19 will function as a resilient distance element arranged concentrically around the exterior ring 16 and is arranged to be fitted into a generally circular opening 21 defined in the wheel bearing housing 20.
  • the sleeve element 19 is intended to be fixed in position by means of a separate, co-operating component in the form of a retainer ring 22, which is conical in shape and intended to be pressed over the end portion of the exterior ring 16, i.e. the end portion facing away from the wheel hub 10.
  • the retainer ring 22 is so designed as to allow being positioned along generally the same longitudinal extension as the sleeve element 19, between a first restriction surface 23 and a second restriction surface 24, the first restriction surface 23 being a shoulder or a countersunk groove in the exterior ring 16 and the second restriction surface 24 being a shoulder in the wheel bearing carrier 20.
  • the two restriction surfaces 23, 24 are formed so as to be facing each other and extending along the circumference of the exterior ring 16 and the wheel bearing carrier 20, respectively.
  • Fig. 2 shows a perspective view of the sleeve element 19 and the retainer ring 22.
  • the sleeve element 19 is designed with a first, mainly cylindrical portion 25, extending concentrically around the axis 3, and a second, flange-like section 26, extending radially outwards from the axis of rotation 3.
  • These protrusions 27 are shaped so as to be somewhat compressible and resilient, and are preferably evenly spaced along the circumference of the flange 26.
  • the sleeve element 19 as well as the retainer ring 22 are manufactured from an electrically insulating material, which is furthermore somewhat elastic.
  • An example of a suitable material with these properties is polyamide.
  • the wheel bearing carrier 20 is preferably provided with a chamfered edge 28 extending circumferentially around the opening 21. Furthermore, the end portion of the exterior ring 16 that is facing the wheel hub 10 is preferably shaped with larger dimensions than said opening 21.
  • the distance elements 27 provide a certain resilient function, as they are elastic. This allows the sleeve element 19 to be located in a correct position and to be snapped into place, even if any measurement deviations would exist in the opening 20.
  • Figs. 3a and 3b illustrate a second embodiment form of the present invention.
  • Fig. 4 shows a portion of a sleeve element 19' intended for this second embodiment.
  • the sleeve element 19' is generally shaped in the same way as the sleeve element shown in Figs. 1 and 2, however with the difference that it comprises some deformations, preferably consisting of a number of elevated portions 29 and sunk portions 30, respectively.
  • Fig. 4 shows only one single elevated portion 29 and one sunk portion 30.
  • the elevated and sunk portions, 29 and 30, respectively, are comprised, according to the embodiment, of strips punched out of the cylindrical portion 24' of the sleeve element 19' and shaped so as to become bent somewhat upwards and downwards, respectively, relative to the circumferential surface of the sleeve element 19', i. e. in a radial direction.
  • the sleeve element 19' comprises a radial flange 26' and a number of protrusions 27', similar to what was discussed above with reference to Figs. 1 and 2.
  • Fig. 3a which is a cross sectional view taken at a certain position where an elevated portion 29 is located
  • the wheel bearing carrier 20' is shaped with an internal, generally annular groove 31 , intended for receiving the respective elevated portion 29.
  • Fig. 3b which is a cross sectional view taken at a position where a sunk portion 30 is located
  • the exterior ring 16' is provided with another, generally annular groove 32, intended for receiving said sunk portion 30 when the sleeve element 19' is fitted. It may further be seen from Fig.
  • Fig. 3a that the wheel bearing carrier 20' is provided with a chamfered edge 28', in analogy with what was explained above, while Fig. 3b shows that also the exterior ring 16' is provided with a chamfered edge 33.
  • This arrangement facilitates the assembly of the complete arrangement, when the sleeve element 19' is first placed onto the exterior ring 16' in such a way that the respective sunk portion is entered towards the corresponding groove 32 and will snap into place. Subsequently, the wheel bearing with the sleeve element 19' is entered into the wheel bearing carrier 20'.
  • the sleeve element 19 may be made of different materials, preferably resilient plastic materials.
  • the above described deformations, 29, 30, may be formed in various ways, e.g. like short, punched strips (as shown in the drawings), cast resilient protrusions or the like.
  • protrusions 27 (or 27') described above may be replaced by an annular, elastic component protruding somewhat from the flange element 26 (or 26') and preferably having its extension around principally the whole circumference thereof.
  • retainer ring 22 may alternatively be made with an undulating shape along its periphery.
  • the sleeve element 19 may be provided with some adhesive agent, e.g. glue, to prevent any rotating motion relative to the exterior ring 16 (or 16') and the wheel bearing carrier 20 (or 20').
  • some adhesive agent e.g. glue
  • the sleeve element may also be provided with knurls or similar.
  • Figs. 3a, 3b and 4 may utilise protrusions, 29 or 30, directed either upwards or downwards, or both.
  • the flange 26' (see Fig. 4) may in principle be omitted, as the deformations 29, 30 are then providing the axial locking of the sleeve element 19'.
