Abstract
An outer member of a constant velocity ratio universal joint, comprising two parts axially secured together. The first part 1a has internal grooves 3 which receives balls 7 for torque transmission with an inner joint member 4, and a second part 1b which interfits axially with the first part and has a cross-sectional shape which co-operates with the internal cross-section of the first part for torque transmission. The second part of the outer joint member is adapted to be connected to a transmission element such as a shaft or differential output member 8. <IMAGE>
Description
SPECIFICATION
Constant velocity ratio universal joint
This invention relates to a constant velocity ratio universal joint, comprising a hollow outer member having a number of grooves in its interior, an inner joint member disposed within the outer joint member, and having a number of exterior grooves facing the grooves in the outer joint member, and a plurality of balls between the inner and outer joint members, one in each facing pair of grooves thereof, for torque transmission between the joint members.
More particularly, the invention is concerned with means whereby the outer member of such a joint can be connected for torque transmission to a tubu- lar shaft, gearbox output member, or other transmission element. It is known for the outer joint member to be provided with an outwardly extending flange, to enable itto be boited to a corresponding flange on a transmission element, but this occupies a relatively large space and is expensive.
It has been proposed, in German OLS 1,903,938, that the outer joint member can itself serve as a side gear of a differential. The joint member itself has gearteeth. This renders the design of the outer joint member complex, in that the characteristics of the differential gearing as well as the universal joint have to be taken into consideration, and it is expensive both to initially produce and to replace if required. It has also been proposed, in DE-GM 7421 287 that a torque transmitting connecting between an outer joint member and flange or shaft can be achieved by use of a sleeve into which the joint member fits, but this requires the use of the sleeve itself as a separate component and the provision of a special cross-sectional shape on the joint member.
It is the object of the present invention to provide an effective yet economical connection between a joint member and other transmission element.
The invention provides that the outer joint member comprises a first part having said grooves, and a second part adapted to be connected to a transmission element, said second part having a portion which fits within said first part and has a crosssectional shape which interfits with the internal cross-sectional shape thereof for torque transmission, and there is provided means for axially securing said first and second parts together.
A joint according to the invention is particularly advantageous if it is used at the output of a differential gear, since the output element of the differential can constitute the second part of the joint outer member. Such an element is not significantly more complex or expensive than an output flange, whilst the first part ofthe outer joint member is simpler than an outer joint member itself having a flange.
The weight of the joint is reduced, and a common design of first part of the joint outer member can be used with different designs of second part for different applications.
In addition, assembly and removal of a drive shaft in a motor vehicle is simplified by use of joints according to the invention.
The second part of the joint outer member may have projections corresponding in cross-section to the grooves in the first part of the joint member. In this case, no change in the design of the part of the outerjoint member having the grooves therein is necessary.
The means which secures the first and second parts of the outer joint membertogether may be a securing ring engaging recesses in the first and second parts of the joint member.
The invention will now be described by way of example with reference to the accompanying drawings, of which :- Figure 1 is a section through part of a differential gearing and a drive shaft having a universal joint according to the invention, in dis-connected condition;
Figure 2 shows the arrangement of Figure 1, in assembled condition;
Figure 3 is a section of the first part of the outer joint member of the joint according to the invention;
Figure 4 is a section of the second part of the outer joint member;
Figures 5 and 6 are respectively longitudinal and transverse cross-sections of part of a universal joint according to the invention.
Referring firstly to Figures 1 and 2, there is shown a constant velocity ratio universal joint whose outer joint member comprises a first part 1 with a cylindrical internal bore 2 having circumferentially spaced longitudinally extending grooves 3 formed therein.
Within the outer joint memberthere is an inner joint member 4 having a part-spherical outer surface with circumferentially spaced straight grooves 5 therein which face the grooves in the outer joint member.
An annular cage 6 is disposed between the inner and outer joint members, and has apertures receiving a plurality of balls 7 one in each facing pair of grooves in the joint members, for torque transmission between the members. The inner joint member 4 receives, by a splined connection, a drive shaft 8 and a boot 9 is connected between the outer joint member and drive shaft for sealing purposes.
At 10 there is indicated generaliy part of a differential gearing, of which a side gear 12 forms part and is connected to an output element 11. The element 11 is integral with a shallow cup-shaped part 13 at the end thereof external to the casing of the differential gearing.
The outer joint member 1 can be considered as comprising two parts, of which the first part 1a (Figure 2) has the grooves 3 therein and the second part 1b is constituted by the element 13. The part 1b fits within the first part 1a, and has a cross-sectional shape which corresponds to the internal crosssectional shape of the first part so that torque can be transmitted between these parts. A securing ring 14 holds the two parts of the outer joint member together axially, and a sealing ring 15 held on the part 1 b engages the end face of the part 1 a to seal the joint.
Referring now to Figure 3, this shows the part 1a of the joint outer member 1 in cross-section. In this
Figure, the cylindrical internal surface thereof is shown at 16, and the grooves at 3. The element 13 is shown in Figure 4, and the part 1 b which fits within the part 1 a of the outer joint member has a cross
sectional shape with part cylindrical portions 17 and
protuberances 18 which fit within the grooves 3.
Thus torque can effectively be transmitted between the two parts of the outerjoint member.
In Figures 5 and 6 is shown in more detail one possible arrangement of the securing ring 14 by which the two parts of the outer joint member are held together. The ring 14 occupies a groove which extends circumferentially of the outer joint member, intersecting both parts of the joint member in a groove extending circu mferentially thereof. Ears at the adjacent free ends of the ring 14 are accessible through a recess 20 in the joint member 1 to permit dismantling, which recess is normaily covered by a sealing ring 15 which is of different design to the sealing ring shown in Figures 1 and 2.
