Abstract
An assembly of an outer race of a constant velocity joint and part of a motor vehicle wheel bearing, wherein the outer race has a first bore and an internal groove in the bore, the bearing part and the race being held in assembled position by a spring ring engaged in the groove and in an external groove of the bearing part which has a second bore with an open end, the ring having, adjacent its ends, arms which extend generally radially inwardly through a slot extending radially of the second bore between an inner end open to the second bore and an outer end at the external surface of the bearing part, the slot extending axially between the external groove and an end of the bearing part.
Description
- This invention relates generally to the securing together against relative axial movement of two members in telescopic relation. The members are secured together by a spring ring which is received in cooperating grooves, an internal groove in the external member and an external groove in the internal member. In particular the invention relates to securing together the outer race of a constant velocity joint and part of a motor vehicle wheel bearing.
- Various proposals have been made for securing together the outer race of a constant velocity joint and part of a motor vehicle wheel bearing. Attention is drawn to U.S. Pat. No. 6,022,275 issued Feb. 8, 2000 to SKF Industrie S.p.A. and U.S. Pat. No. 6,193,419 issued Feb. 27, 2001 to GKN Automotive AG. Reference is also made to the publication WO99/13232 in the name of GKN Automotive AG. In this latter publication a spring ring is used which has arms at its ends which extend outwardly and these arms are embraced by a holding element which can hold the ring in one of the grooves while the parts are assembled and then removed to allow the ring to engage both grooves. Access to the holding element may be through the hole in the vehicle suspension knuckle which is normally used for an ABS sensor.
- The area round the exterior of the wheel bearing is very confined and there is little space to manipulate the holding element.
- It is an object of the present invention to provide an arrangement in which, when securing together the outer race of a constant velocity joint and a wheel bearing by means of a spring ring, the spring ring can be operated upon from the wheel side of the assembly and can thus allow easy assembly and disassembly of the parts in situ on a vehicle.
- Another object of the invention is the provision of a sealing ring to seal the splined connection between the hub and the outer race of the constant velocity joint to prevent the ingress of road dirt etc. into the splined connection and the internal and external grooves.
- According to one aspect of the invention we provide a method of securing together, by means of a spring ring, an external member in telescopic relation with an internal member, wherein the external member has a first bore and an internal groove in the first bore, wherein the internal member has an external groove, a second bore and a slot extending radially of the second bore between an inner end open to the second bore and an outer end at the external surface of the internal member, the slot extending axially between said external groove and an end of the internal member, wherein the spring ring is engaged in said grooves to secure the members together and has, adjacent to its ends, arms which extend generally radially inwardly; the method comprising mounting the spring ring in the external groove so that the arms extend inwardly through said slot into the second bore, releasably holding the ring in a contracted state so that it lies substantially within said external groove by engaging said arms in the second bore with holding means, telescoping the members together while the arms are engaged with the holding means until the grooves in the members are mutually aligned and disengaging the holding means from said arms to release the ring so that the ring expands to engage in both of the mutually aligned grooves to secure the members together.
- Preferably the external member is part of the outer race of a constant velocity joint and the internal member is part of a motor vehicle wheel bearing.
- According to another aspect of the invention we provide an assembly of an outer race of a constant velocity joint and part of a motor vehicle wheel bearing, wherein the outer race has a first bore and an internal groove in the bore, the bearing part and the outer race being held in assembled position by a spring ring engaged in said groove and in an external groove of the bearing part which has a second bore with an open end, the ring having, adjacent its ends, arms which extend generally radially inwardly through a slot extending radially of the second bore between an inner end open to the second bore and an outer end at the external surface of the bearing part, the slot extending axially between said external groove and an end of the bearing part.
- In this arrangement the inwardly projecting arms of the ring can be operated upon through the open end of the second bore and can be gripped so as to locate the ring wholly in the external groove on the wheel hub part or to allow the ring to expand so as to be located in both the internal and the external grooves.
- The invention will now be described in detail with reference to the accompanying drawings which show four assemblies of a constant velocity joint outer race and a motor vehicle wheel bearing embodying the invention.

- FIG. 9 shows the sealing ring and how the spring ring engages the internal and external grooves.
- Referring first to FIG. 1, there is shown an assembly of the
outer race 10 of a constant velocity joint and a motor vehicle wheel bearing assembly indicated generally at 11. Theassembly 11 includes ahub 12 having aflange 13 which carries bolts (not shown) to receive a vehicle road wheel (not shown) which is located on aspigot 15. The hub has abore 16 and is rotatably mounted in afixed part 17 which may be connected by bolts, not shown, to a suspension knuckle of a vehicle. There is a rolling element bearing 19 between thehub 12 and thefixed part 17. In the example shown the bearing is a double-ball bearing but may be a roller bearing. The outer races of the bearing are formed directly in thefixed part 17. The inner race of one of the bearing rows is indicated at 20 and is formed on the hub itself. The inner race of the other bearing row is indicated at 20 a and is formed on atubular securing element 22. - The
tubular securing element 22 has abore 23 and serves to pre-load thebearing 19 via thebearing race 20 a and to locate thehub 12. At its right-hand end in FIG. 1 the securing element has aflange 24 the outer surface of which is splined at 25. Atubular part 27 of the securing element passes through thebore 16 of the hub and at its left-hand end is swaged outwardly at 28 to engage asurface 28 a on the hub. As the swaging takes place a load is applied to the securing element so that it loads thebearing race 20 a and thus pre-loads thebearing 19. Thebore 16 of thehub 12 and thepart 27 of the securing element haveinter-engaging splines 18. - The
outer race 10 of the constant velocity joint hasball tracks 10 a and atubular neck portion 30 which is internally splined at 31. Thesplines 31 in the neck portion of the outer race engage thesplines 25 on theflange 24. Theouter race 10 will contain an inner race, cage and balls (not shown). - Referring to FIG. 9 the
neck portion 30 of the outer race is provided with aninternal groove 32 while theflange 24 is provided with anexternal groove 33. Aspring ring 34 holds the parts aligned as will now be described. - The ring is shown in more detail in FIGS. 5 and 6. The ring comprises a generally
circular part 35 which is not a complete circle but has agap 36. At theends 38 of its circular part the ring hasarms 37 which project generally radially inwardly. As shown in FIG. 6, thearms 37 lie in a plane which is inclined to the plane which contains thecircular portion 35. However, the arms could be in the same plane as the rest of the ring. - As shown in FIGS. 1 and 2, the
flange 24 is provided with aslot 29. The slot extends radially of the flange from theouter surface 25 thereof to thebore 23. It also extends from the right-hand end of theflange 24 in FIG. 1 to the left-hand end 40 of thegroove 33 in the flange. To assemble theparts ring 34 is first assembled on theflange 24 so that it is received in thegroove 33. Thearms 37 pass inwardly into thebore 23 through theslot 29. - By means of a pair of long-nosed pliers, not shown, inserted into the
bore 23 from the left-hand end, thearms 37 can be moved towards one another thus to contract the circular part of thering 35 so that the ring is wholly located in thegroove 33. Theouter race 10 can then be slid onto theflange 24 so that thesplines grooves arms 37 can then be released with the result that thering 34 assumes the position shown in FIG. 9 and the parts are secured together. - If desired there may be an O-
ring seal 41 interposed between theflange 24 and the adjacent end of theportion 30 to exclude dirt etc. from the inter-engaging splines 25 and 31 and thegrooves cavity 42 in theouter race 10 is sealed by means of adiaphragm 43 and the left-hand end of thebore 23 by aremovable cap 42 a. - To remove the
outer race 10 from the bearing assembly long-nosed pliers are again inserted into thebore 23 from the left-hand end, which is the wheel side on the vehicle, and grip the arms to contract the ring into thegroove 33 thus allowing the outer race to be removed. This is a convenient method of assembly and disassembly since it is carried out from the wheel side of the assembly so that it is possible to disassemble the bearing and the CV joint outer race when the assembly is in situ on a vehicle. It is also possible to reduce the distance X shown in FIG. 1 between the centre line of the CV joint outer race and the bearing by this construction. Thecap 42 a keeps dirt out of thebore 23 and can be removed to insert pliers to compress thering 34. - FIG. 1a differs from FIG. 1 only in the fact that the
inner race 20 a in FIG. 1 which is formed on the securingelement 22 is, in FIG. 1a, replaced by a separateinner bearing race 21 which is located on aseat 26 on theflange 24. Thebearing 19 is pre-loaded via the bearingrace 21 as the left-hand end of the securing element is swaged over at 28. Similar parts in the two figures are referred to by the same reference numerals. - Referring now to FIGS. 3 and 4, these show an embodiment of the invention which differs from that shown in FIG. 1 by the provision of a holding element to hold the arms of the spring ring apart. The same reference numerals are therefore used in FIGS. 3 and 4 as in FIGS. 1 and 2 but with the prefix
- In FIGS. 3 and 4, the
bore 123 in the securingelement 122 has an internal flange 44 which provides acentral passage 45 in which is received a holdingelement 46. The holding element is made of a non-metallic material which may be resilient and has a first part 47 which is received between thearms 137 as shown in FIG. 4. The part 47 has oppositely directedsurfaces 48 which engage with inwardly opposed surfaces 49 on thearms 137. - A second part of the holding element is indicated at47 a, is cylindrical and is a tight fit in the
passage 45. Thispart 47 a has aflange 50 so that it is prevented from moving too far to the right in FIG. 3. Atab 51 is formed on the holding element so that it may be gripped. - The
parts ring 134 has expanded to the position shown in FIG. 9 the holdingelement 46 is inserted into thepassage 45 so that the first part 47 is engaged between thearms 137 and holds them apart thus holding the ring in the position shown in FIG. 9. - In the embodiment of FIGS. 3 and 4 there is a sealing ring52 similar to the
ring 41 shown in FIG. 7 and the inner race 53 of the right-hand row of balls is formed directly on the hub. - FIG. 7 shows a somewhat different construction to that shown in FIGS.1 to 6. In this construction there is no securing
element flange 58 with bolts for receiving a road wheel. The hub has abore 59 and at its right-hand end has an outwardly swagedportion 60. This swaged portion acts to pre-load a bearing 61 between the hub and a fixedportion 62 by pre-loading a separate inner race 63 as described above. Thus theportion 60 engages the right-hand end of a securing ring 64 which engages the race 63. The external surface of the securing ring is splined at 65 to engageinternal splines 66 on the neck portion of theouter race 55. - Both the outwardly swaged
portion 60 and the securing ring 64 are slotted at 67 and 68 respectively. In this case the internal groove such as 32 in FIG. 9 is formed in theouter race 55 as before but the external groove such as 33 is formed in the securing ring 64. Theslot 68 extends from the right-hand end of the securing ring to intersect with the external groove such as 33 in the securing ring. - Assembly of the parts is as described in relation to FIGS. 1 and 2 in that the
spring ring 72 of the form shown in FIGS. 5 and 6 is mounted in the external groove in the securing ring 64. Thespring ring 72 is then contracted by being held through thebore 59 by pliers as described above to contract the spring ring into the external groove. Theouter race 55 of the constant velocity joint is then slid onto thesplines 65 of the securing ring, the arms of the spring ring are released and the ring takes up the position such as shown in FIG. 9 in which it is both in the external groove and in the internal groove. As described above an O-ring seal 70 is provided between the securing ring 64 and the adjacent end of the neck of theouter race 55 of the constant velocity joint. - As in FIG. 3, an
internal flange 73 is provided in thebore 59 which receives a holdingelement 69 which acts as described in relation to FIGS. 3 and 4. - Where an element has been swaged outwardly as described this may be conveniently done by orbitally forming which allows the bearing to be pre-loaded as described simultaneously with the formation of the outwardly swaged part.
- The holding element described may be so constructed as to hold the arms of the spring ring in a position in which the ring is received wholly in the external groove in one position and then may take up another position to hold the arms apart as shown in the drawings.
- The
diaphragm flange - The spring ring used will normally be of rectangular section as shown in FIG. 9 and will normally have a greater dimension radially than axially. The O-
ring 41 may also be of rectangular section. - Oil seals such as71 in FIG. 1 may be installed on each side of the
bearing
