Abstract

The hub component (10), constructed as a machined forging, is composed of a main body (11) and a radial flange (17). The main body (11) defines a hub portion (12) containing a though bore (13) and having a groove (15) forming a bearing raceway on its outer periphery. The flange (17) has bores (7) for receiving bolts to secure the component to a vehicle wheel. To reduce the weight of the component but without adversely effecting the stiffness and strength of the component, the flange (17) has a differential thickness and openings (19) extending over the greater part of its area in a reduced thickness region of the flange (17).

Description

2351950 A HUB COMPONENT FOR VEHICLE WHEELS The present invention relates
to a hub component usable in vehicle bearing hub units.
According to the invention a hub component comprises a cylindrical hub portion with a bearing raceway on its outer periphery and a radial flange integral with the hub portion wherein the flange is provided with bores for receiving fixing bolts or the like aswell as other openings extending through the flange to reduce the weight of the component.
In a preferred embodiment, the flange also has a differential thickness to further reduce the weight of the component. The flange may have an inner region merging into the hub portion and an outer rim which has the same thickness as the inner region. A reduced thickness central region radially between the inner region and the rim may then contain both the bores and other openings.
The openings can take various forms, such as arcuate slots distributed around the circumference of the flange between the bores.
The reduction in the weight of the component can be achieved without a significant reduction in the stiffness of the component.
2 The invention may be understood more readily, and other features of the invention may become apparent, from consideration of the following description and accompanying drawings wherein:
Figure I is a cross-section view of a typical prior art hub component-,
Figure 2 is a perspective view of part of the hub component shown in Figure 1; Figure 3 is a perspective view of part of another prior art hub component and
Figure 4 is a perspective view of part of a hub component constructed in accordance with the invention.
As shown in Figures I and 2 a hub component 10 of known construction is composed of a main cylindrical body I I forming a hub portion 12 with a through bore 13. The through bore 13 communicates with a coaxial enlarged recess 14 at one end of the component 10. A groove or raceway 15 is provided in the outer periphery of the body I I for receiving balls of an angular contact bearing so the main body I I forms the inner ring of the bearing. A shoulder 16 is formed at the other end of the component 10 to define the raceway 15. A radial flange 17 extends from the main body I I adjacent the one end. This flange 17 has a number of bores 7 distributed around its circumference for receiving bolts used to secure the hub component 10 to a vehicle wheel.
3 Figure 3 shows a modified construction where the flange 17 has an outer ring 17' which is somewhat thinner than the central region 18 of the flange 16. The mass and hence the weight of the component 10 is reduced by this measure.
Figure 4 depicts a hub component 10 constructed in accordance with the invention where like reference numerals depict like parts to Figures 2 and 3.
In Figure 4 the hub component 10 is provided with arcuate slots or openings 19 disposed between the bores 7 and distributed around the circumference of the flange 17.
The flange 17 is composed of an inner region 20 and an outer rim 21 with the same thickness. A central region 22 between the rim 21 and the inner region 20 has a reduced thickness and the bores 7 and openings 19 are provided in this central region 22.
The provision of the openings 19 and the reduced thickness region 22 significantly reduces the mass and hence the weight of the component 10 without adversely effectively the stiffness and strength of the flange 17.
In a preferred design i) the ratio of the thickness of each of the regions 21,20 of the flange to the central region 22 is around 2:1 and/or ii) the ratio of the aggregate areas of the openings 19 to the area of the material in the region 22 is around 4- 1.
4 The hub component 10 shown in Figure 4 as in the prior art designs can be made as a forging which is then machined.

Claims (5)

  1. Claims
    I. A hub component comprising a cylindrical hub portion with a bearing raceway on its outer periphery and a radial flange integral with the hub portion, wherein the flange is provided with bores for receiving fixing bolts or the like aswell as the openings extending through the flange to reduce the weight of the component.
  2. 2. A hub component according to claim I wherein the openings are arcuate slots distributed circumferential ly around the flange.
  3. 3. A hub component according to claim I or 2, wherein the flange also has a differential thickness.
  4. 4. A hub component accord to claim I or 2, wherein the flange has an inner region merging with the hub portion, an outer rim with the same thickness as the inner region and a central region between the rim and the inner region, the central region having a smaller thickness than the rim and the inner region and the bore and the openings are provided in the central region.
  5. 5. A hub component substantially as described and as illustrated in Figure 4 of the accompanying drawings.
