Description

SPECIFICATION Hub assembly This invention relates to a hubassemblyfora drivablewheel of a motorvehicle, comprising a hub member arranged to be rotatably supported by bearing means relative to a carrier; and a constant velocity ratio universal joint having a member connected fortorque transmission with the hub member by axially interfitting projection and recess formations provided thereon, and fastening means holding the joint member and hub membertogether with said projection and recess formations in engagement with one another. Such a hub assembly will hereafter be referred to as a hub assembly ofthe kind specified.
One form of hub assemblyofthe kind specified is disclosed in British Patent 2,097,735. The hub member and the outer member of the universal joint have interengaging projections and recesses in the form of circumferentially spaced dogs engaging in complementary recesses, e.g. apertures. The fastening means holding the hub member and joint membertogethercomprises a central bolt.
Anotherform of hub assembly ofthe kind specified is disclosed in British Patent 2,097,734. In this example, which is otherwise generallysimilarto that of British Patent 2,097,735, the interfitting projection and recess formations comprise interfitting teeth which are of a configuration such that they engage in a clearance-free manner.
Such hub assemblies have advantages that the hub member, with its bearing means, and the universal joint can be supplied as pre-assembled units which are easily fitted together. They are readily dismantled for repair or servicing purposes.
On the other hand, production ofthe projection and recess formations, whether in the form of teeth or dogs, is very labour and cost intensive. This applies whether such teeth are produced by machining operations or by conventional cold forming, upsetting, or like deformation processes.
Accordingly, it is the object of the present invention to provide, in such a hubassembly,for production ofthe inter-engaging projection and recess formations at lower cost, while at the same time having a high degree of dimensional accuracy.
According to the present invention, we provide a hub assembly ofthe kind specified wherein said projection and recess formations are provided on the joint member and the hub member by an incremental deformation process (rotary forging or orbital pressing).
The universal joint member, which is preferably the outer member of the joint, preferably has a surface which faces the hub member and which, apart from projection and recess formations such as circumferentially spaced teeth, is generally flat and in particulardoesnothaveanygenerallycylindrical projection interfitting with the hub member.
The material used for the parts subjected to rotary forging may be a steel whose carbon content is in the range between 0.4% and 1.2%.
The invention has a number of advantages, particularly being that formations such as teeth can be produced with relative ease and economy while at the same time being characterised buy a high degree of accuracy. Afurther advantage of using the process of rotary forging isthat pressing forces required are relatively low in comparison with simple cold forming techniques. For example, vocording to Mossle (Kaltmassivumformung durch Taumelpressen) in Z Industrie No. 79, 03.10.79, page 66, forworkpieces having a diameter of the orderof 80to 100mm the press design for rotaryforging does not have to have a nominal force of more than 1 600kn.
The basic incremental deformation principle ofthe process variously described as rotary forging or orbital pressing, as described by Mossle and others, is that the workpiece is formed between two dies of which one carries out a defined movement which may be described as a rotary movement, an orbital movement, or a rocking movement, about a centre point of the die. In the repeated movement of the die the forming force at any instant is concentrated in a restricted forming zone which moves across the entire surface ofthe workpiece with movement of the die. The reduction ofthe area of contact between the workpiece and die results in a considerable decrease in the total force required to be exerted by the press in which the operation is being carried out, and in the stress on the dies.
To enable rotary forging to be efficiently applied to the parts of a hub assembly according to the invention,the blankforged parthasto be designed in an appropriate mannerand a suitable material has to be selected. The present invention meets these conditions firstly in that the surface of the outerjoint memberfacing the hub member is of a generallyflat design without any cylindrical projection. Secondly, the steel used for the parts may have a carbon content in the range 0.4% to 1.2%. Although in the general opinion ofthose skilled in the art a steel of this composition is less suitable than some other compositions for being subjected to forming operations, in practice rotary forging using such a material has proved to be successful.The increased carbon content renders the steel more suitable for, in the case ofthe hub member, acting as the inner race ofthe bearing means by which it is supported, without requiring the provision of a separate bearing inner race or races.
The invention will now be described by way of example with reference to the accompanying drawings, of which: : - Figure lisa section through a hub assembly according to the invention; Figure2 is a diagrammatic illustration ofthe rotary forging technique used for making parts according to the invention; Figure 3 shows possible movements of a die in the course of the rotary forging operation; Figure4 illustrates forces arising during rotary forging in comparison with convention cold forming or upsetting.
Referring firstly to Figure 1 ,there is illustrated a hub assembly comprising a hub member 1 provided with a flange 2 for wheel attachment. The hub member has a portion 22 which constitutes the inner race for a double row angular contact ball bearing having an outer bearing race 3 and balls 4, i.e. a so called radiax bearing. The outer race 3 has threaded apertures to enable it to be connected to a wheel carrier member forming part of a motorvehicle suspension. At the side offlange 2 opposite the bearing race part 22, hub 1 is provided with an annular projection 6 for receiving and centering a brake disc.
The assemblyfurthercomprisesa constant velocity ratio universal joint 5 of known type. Thus, the constant velocity ratio universal joint comprises an outer joint member7 having circumferentially spaced grooves 8 in its interior, and an innerjoint member 9 having grooves 10 which face the grooves in the outerjoint member. A plurality of balls 11 are received one in each facing pair of grooves in the joint members, and the balls are received in windows of a cage 12. The innerjoint member9 has a splined bore in which is received the splined end portion of a shaft 13. Aflexible sealing boot 14, connected between the outer joint member7 and shaft 13, retains lubricant in and excludes dirt fro the interior ofthe universal joint.
The outer joint member7 has a portion 15which facesthe hub member 1. The portion 15 ofthe joint outer member and a facing portion 1 a of the hub member have inter-engaging projection and recess formations in the form of ci rcu mferentially spaced teeth 16, which are produced by a rntaryforging process as hereafter described. The teeth 16 serve to transmittorque between the joint outer member and hub member, and these parts are held together by an axially extending bolt 19 engaging in a threaded bore 18 in the joint outer member. The head ofthe bolt 19 lies within a space 20 within the centering projection 6.
The outer joint member and hub member are thus connected togetherfortorque transmission in a manner which, by removal of bolt 19, permits easy dismantling. The head of bolt 19would normally be accessible through the centre of the vehicle's wheel (not shown), so that if required the shaft 13 and universal joint can be readily removed from a vehicle.
As above mentioned, the interengaging teeth 16 on the portion 15 ofthe outer joint member and the portion 1 a of the hub member are provided by subjecting each ofthese parts to a rotary forging process. As is illustrated in Figure 2, such a process is carried out by subjecting a workpiece 25 to an operation between a fixed lower die 26 and an upper die 24which undergoes an orbital or rotary motion relative to the lower die. As shown in Figure 2, the upper die may move such that its axis, inclined to the axis ofthe lower die at an inclination Y1,describes a conical form. In Figure 2, the lower die 26 is shown as provided with an ejector 27.
Various rotary or orbital movements of the upper die relative to the lower die are possible, and these are shown in Figure 3.
In Figure3a, a circular motion of the upper die is shown. The instantaneous contact area between the upper die and workpiece moves in the circumferential direction only. This motion is particular suitable if an intense material flow is required, e.g. when forming workpieces with relatively large and thin flanges.
Figure 3b shows a spiral movement of the instantaneous area of contact betweenthe upperdie and workpiece. This is advantageous if, due to a complicated shape ofthe centre portion ofthe workpiece, a high flow of material in such region is required.
Figure 3c shows a reciprocating movement in one plane of the instantaneous area of contact between the upper die and workpiece. Although no rotary motion is involved, the process is still known generically as rotary forging. This is particularly suitableforforming elongateworkpieces.
Figure 3d shows a three-lobed movement of the instantaneous area of contact between the upper die and workpiece. Such a movement is particularly suitable forforming workpieces with concentric ribs, such as bevel gears ortoothed clutch discs.
Figure 4 illustratesthe comparison between stresses arising during a conventional cold forming or upsetting operation between flat dies, compared with a rotary forging operation using an orbiting die.
In both cases, direct stress is indicated bythevertical axis QZ. The workpiece has a diameter d and a thickness S. In the left hand diagram, thefull4ace contact surface between the upper die and workpiece is indicated at 28, with a high maximum stress QZ max. In the right hand diagram, the much smaller area of contact between the orbital rotary forging die and the workpiece is indicated at 29, and the lower maximum value of QZ.
