Description
SPECIFICATION
Universal joint, particularly for steerable drive shafts in motor vehicles
The invention relates to a universal joint with at least four bearing positions arranged in pairs in mutually staggered planes, particularly for steerable drive shafts in motor vehicles, the universal joint having at least four bearing positions arranged in pairs, the pairs being disposed in mutually offset planes, and at least one stellate joint spider which is provided with four journals arranged in mutually diametrally opposite pairs, the respective axes of which are located in the planes, and with at least four bearing bushings constituting the bearing positions in association with the journals, each of said bearing bushings surrounding a journal and enclosing the radially outer end face thereof, a bearing being provided in each case between the outer peripheral surfaces of the journals and the inner peripheral surfaces of the bearing bushings and a lubricant channel being provided at the end face of each of the journals leading to the respective bearing.
In known universal joints of this type, the ends of the two drive shafts connected by the universal joint are of bifurcate construction. Each fork encloses two diametrally opposed bearing bushings. The bearing bushes are attached rigidly to the forks and lubricating nipples passing through the bearing bushings lead to the individual bearing positions. A separate lubricating nipple is associated with each bearing position so that when the joint is to be lubricated each bearing position must be lubricated separately through the lubricating nipple provided there. This requires time and increases the cost of the regular maintenance and lubrication service for the motor vehicle.
The underlying aim of the invention is to produce a universal joint of the type initially defined in which all four bearing positions of the universal joint are connected by a common lubrication system and can be lubricated simultaneously from a single position. At the same time the invention seeks to construct the universal joint in such a way that the common lubrication path is maintained, irrespective of the nature of the construction at the joint end of the two drive shafts connected by the universal joint.
Particularly, the universal joint is intended to be suitable for use in the case of bifurcate construction of the joint ends of the drive shafts for receiving the bearing bushings at mutually
diametrally opposed bearing positions.
According to the invention there is provided a
universal joint having at least four bearing
positions arranged in pairs, the pairs being disposed in mutually offset planes, and at least one stellate joint spider which is provided with four journals arranged in mutually diametrally
opposite pairs, the respective axes of which are
located in the planes, and with at least four
bearing bushings constituting the bearing positions in association with the journals, each of
said bearing bushings surrounding a journal and
enclosing the radially outer end face thereof, a
bearing being provided in each case between the
outer peripheral surfaces of the journals and the
inner peripheral surfaces of the bearing bushings
and a lubricant channel being provided at the end face of each of the journals leading to the respective bearing, wherein the joint spider includes two mutually intersecting central bores each extending along the axis between two diametraily opposed journals, each of said bores opening at one end face of the respective one journal and being closed before the end face of the other journal, said central bores communicating
mutually at an intersection point, a transverse bore is located in each of the journals close to the
radially inner end of the bearing positions oriented towards the joint spider centre, extending in each case from the outer peripheral surface of the journal into the respective central bore in the
spider and in each central bore there is inserted a
coaxial tube which forms in each case between its
outer wall and the inner wall of the respective
central bore an annular space sealed at its end face which in each case connects the transverse
bore closest to the orifice of the respective central
bores to the intersection point of the two central
bores.
The universal joint according to the invention
requires to be lubricated only at a single position,
whilst all four bearing positions are simultaneously
and thoroughly supplied with lubricant. The
economy of time in maintenance service is
considerable. Furthermore, only a single
lubricating nipple and a single closure plug with an Outlet orifice for the lubricant is necessary for all
four bearing positions. A not inconsiderable
economy of material and components is achieved,
resulting in a general reduction in the cost of the
universal joint. A universal joint in accordance
with the invention is characterised by a simple
construction favourable for production technique,
so that the additional machining and assembly
costs can be kept small.They are relatively
insignificant in comparison to the cost reduction
which can be achieved by the saving of three
lubricating nipples and three closure plugs with
outlet orifices for the lubricant.
In a preferred embodiment of the invention the
central bores are constructed as through bores
aligned with the axes of the diametrally mutually
opposite journals which are sealed at one end by
means of a seal plug.
In another embodiment of the invention a
lubricating nipple is arranged at the closed end of one of the central bore in one bearing bushing and a closure plug provided with a lubricant outlet orifice is arranged at the closed end of the central bore in the other bearing bushing and the axes of the lubricating nipple and the closure plug are substantially aligned with the axes of their
respective central bores.
A lubricant storage space may be provided between the bearing end of the lubricating nipple and the closed end of the central bore; and in another aspect of the invention the diameter of the central bores is greater than the space between the planes in which the respective axes of mutually diametrally opposed journals are disposed. The external diameter of the tubes may be at most equal to the interval between the planes in which the axes of mutually diametrally opposed journals are oriented.
In a further aspect of the invention, the diameter of the central bores is smaller than the distance between the planes in which the respective axes of mutually diametrally opposed journals are oriented, and a radial bore in the spider connects the two central bores at the intersection print in the joint spider.
In yet another aspect of the invention the radial bore starts from an outer surface of the joint spider and is sealed at said outer surface. The coaxial tubes may be enlarged to the diameter of the central bores at least at one end, and in a further modified embodiment of the invention, the central bores are stepped in diameter along their length, the minimum diameter being slightly smaller than the external diameter of the tubes, the mean diameter corresponding to the external diameter of the tubes and the maximum diameter corresponding to the external diameter of the tubes in the enlarged end region.
Studs may be provided in the orifices of the central bores, arranged co-axially therewith, said
studs extending at least to the orifices of the central bores and masking the orifices to provide an annular gap, and in one further aspect of the invention, the studs are retained in the bearing bushings. The studs may be constructed as blind screws with bevels adapted for screwing into the bearing bushings, and the orifices of the central bores may be bevelled.
Two embodiments of the invention will now be described by way of example and with reference to the accompanying drawings in which:
Figure 1 shows a longitudinal section of a first embodiment of a joint in accordance with the invention,
Figure 2 is a section along the line Il-Il in
Figure 1,
Figure 3 is a perspective view of the joint spider of the universal joint shown in Figures 1 and 2 drawn on a smaller scale, and
Figure 4 shows a perspective view of a joint spider for a second embodiment of a universal joint constructed in accordance with the invention, shown to a larger scale and partly sectioned.
The universal joint illustrated in Figures 1 to 4 is particularly for use in steerable drive shafts or axles of motor vehicles. The universal joint has a total of four bearing positions 11-14. Two bearing positions are arranged in each of the planes 1 5 or
1 6, and in fact the axes of two bearing positions lie in each of these planes. The planes 1 5 and 1 6 are each indicated by a chain dotted line in Figures
1 and 2.
The universal joint includes at least one cross shaped joint spider 17, the shape of which may be seen more particularly from Figure 3. The joint spider 17 has four journals 18-21 located mutually diametrally opposite each other in pairs.
The axes 22-25 of the journals 18-21 are respectively mutually aligned in pairs in the planes 1 5 and 16 which are mutually parallel. The axes 22 and 23 of the journals 18 and 19 are aligned with and lie in the plane 15. whilst the axes 24 and 25 of the journals 20 and 21 are perpendicular to the axes 22 and 23, are mutually aligned and lie in the plane 16. The planes 1 5 and 1 6 are offset by a predetermined distance.The journals 18-21 in conjunction with the respective bearing bushings 26-29 form the bearing positions 11-14. Each one of the bearing bushings 26-29 surrounds one of the journals 18-21 and covers the outer end face of the respective journal. A bearing 38, 39, 40 or 41 is arranged in each case between the outer peripheral surfaces 30-33 of the journals 1 8-21 and the internal peripheral surfaces 34-37 of the associated bearing bushings 26-29. The bearings 38-41 are preferably constructed as rolling-contact bearings, particularly as needle-roller bearings.A lubricating channel 50, 51, 52 or 53 leading to the respective bearing 38, 39, 40 or 41 is left clear at each of the end faces of the journals 18-21, namely between their end faces 42 45 and the base surfaces 46-49 of the bearing bushings 26-29.
The end of each bearing bushing 26-29 directed towards the joint spider centre is sealed hermetically against the discharge of lubricant by a double-acting seal 54--57.
As shown in the drawings, the bearing bushings 26 and 27 are rigidly attached to a right-hand drive shaft 58 and the bearing bushings 28 and 29 to a left-hand drive shaft 59. For this purpose the joint ends of the two drive shafts 58, 59 are of bifurcate construction. The bearing bushings 26-29 are maintained non-rotatably in these forks.
The joint spider 17 is provided internally with two mutually intersecting central bores 60 and 61 extending respectively between diametrally opposite journals 18 and 19 or 20 and 21. The two central bores 60 and 61 open in each case at the end face 43 or 44 of the one journal 19 or 20 and are closed adjacent to the end face 42 or 45 of the respectively opposite other journal 1 8 or 21. The two central bores 60 and 61 communicate with each other at the intersection point 62.
A transverse or radial bore 63, 64, 65, 66 extending in each case from the outer surface 30-33 of the journals 18-21 into the respective central bore 60 or 61 is provided in each of the journals 1 8-21 close to the end of the bearing positions 11-14 directed towards the centre of the joint spider. In each central bore 60 and 61 a tube 67 or 68 is inserted which forms in each case an annular space 69 or 70 closed at each end and contained between its own outer wall and the inner wall of the respective central bore 60 or 61. One of the annular spaces 69 or 70
connects in each case the transverse bore 64 or
65 closest to the orifice 71 or 72 of the central
bore 60 or 61 to the intersection point 62.
The central bores 60 and 61 are preferably
constructed as though bores, the axes of which align with the diametrally opposed journals 1 8-21. Axiaily inwardly with respect to the end faces 42 and 45 of the journals 1 8 and 21, the bores 60 and 61 are sealed by means of seal plugs73 or 74. Said plugs 73 and 74 constitute the closed end of the central bores 60 and 61. At these closed ends of the central bores 60 and 61, a lubricating nipple 75 is arranged in a bearing
bushing 26, and a closure plug 76, which has a
lubricant outlet orifice 77, is arranged in the other bearing bushing 29. The axes of lubricating nipple 75 and closure plug 76 are substantially aligned respectively with the axes of the central bores 60 and 61.A lubricant storage space 78 is provided between the bearing end of the lubricating nipple 75 and the end of the central bore 60 which is closed by the seal plug 73.
In the universal joint according to the embodiment shown in Figures 1 to 3 the diameter of the central bores 60 and 61 is smaller than the space between the parallel planes 1 5 and 16 in which the respective axes 22-25 of diametrally opposed journals 18-21 are oriented. In order to establish the connection between the two central
bores 60 and 61 at the intersection point 62, an axial bore 79 connecting the two central bores 60 and 61 together at the intersection point 62 is provided in the joint spider 1 7. This axial bore 79 starts from the surface 80 of the joint spider 1 7 and is sealed there, preferably by means of a plug 81.
In the universal joint according to Figures 1 and 2 the tubes 67 and 68 are enlarged at one end to the diameter of the central bores 60 or 61. The central bores 60 and 61 are stepped in diameter along their length. The minimum diameter of the central bores 60 and 61 is slightly smaller than the external diameter of the tubes 67 and 68. The mean diameter of the central bores 60 and 61 corresponds to the external diameter of the tubes 67 and 68, and the maximum diameter of the central bores 60 and 61 corresponds to the external diameter of the tubes 67 and 68 in the enlarged end region. Due to this construction of the central bores 60 and 61 and of the tubes 67 and 68, an extremely simple assembly and fixing of the tubes 67 and 68 in the central bores 60 and 61 is achieved.The tubes 67 and 68 are inserted respectively from the orifices 71 and 72 of the central bores 60 and 61 into the central bores 60 and 61. The minimum diameter of the central bores 60 and 61 fixes the position of the tubes 67 and 68, since it is smaller than the external diameter of the two tubes 67 and 68. Due to the identical construction of the mean diameter of the central bores 60 and 61 to the external diameter of the tubes 67 and 68, the tubes are seated closely by their one end in the central bores 60 and 61 and thus seal on one side the two annular spaces 69 and 70 which are created by the fact that the maximum diameter of the central bores
60 and 61 is greater than the external diameter of the tubes 67 and 68.Due to the enlargement of the external diameters of the tubes 67.and 68 in their end region, the two annular spaces 69 and 70 are also sealed at the other end by the tubes 67 and 68, without the need of additional seal elements.
Studs 82 and 83 arranged co-axially with the central bores 60 and 61 are provided opposite the orifices 71 and 72 of said bores. The studs 82 and
83 extend towards the orifices 71 and 72 of the central bores 60 and 61, i.e. at least adjacent to the enlarged-diameter end of the tubes 67 and 68, and cover the ends of these tubes except for an annular gap 84 and 85. The studs 82 and 83 are retained in the bearing bushings 27 and 28. They are preferably constructed as blind screws with
bevels adapted for screwing into the bearing
bushings 27 and 28. Conveniently, the orifices 71 and 72 of the central bores 60 and 61 are likewise
bevelled. By virtue of the above described construction of the universal joint, a single
lubrication path connecting all four bearing positions 11-14 is created.During lubrication the lubricant oil or grease, is fed in at the lubricating nipple 75 and emerges from the
universal joint through the lubricant outlet orifice
77 after passing through all the bearing positions 11-14.
The lubrication path of the lubricant is identified
by arrows in Figures 1 and 2. The lubricant passes through the lubricating nipple 75 in the lubricant storage space 78. From here it passes through the
lubricating channel 50 into the bearing 38 which it
lubricates. From the bearing 38 it passes through the transverse bore 63 into the central bore 60
and flows through the tube 67 arranged in said central bore 60. At the orifice 71 of the central bore 60 the lubricant passes through the annular gap 84 out of the tube 67 and passes through the
lubricating channel 51 into the second bearing 39.
From the second bearing 39, the lubricant can now pass through the transverse bore 64 into the annular space 69 between the outer envelope of the tube 67 and the inner wall of the central bore
60. From said annular space 69 the lubricant passes through the axial bore 79 into the second
central bore 61, in this case initially into the
annular space 70 between the inner wall of the
central bore 61 and the outer wall of the tube 68 arranged in the central bore 61 (Figure 2). From the annular space 70 the lubricant flows through the transverse bore 65 into the third bearing 40.
This too is thereby supplied with the lubricant.
From the'bearing 40, the lubricant passes through the lubricating channel 52 and the annular gap 85 into the orifice 72 of the central bore 61 and into the interior of the tube 68 terminating there. The lubricant flows through the tube 68, enters the final end region of the central bore 61 and flows at the end of the central bore 61 closed by the seal plug 74, through the transverse bore 66 into the last bearing 41. From this bearing the lubricant can pass through the lubricating channel 53 into the lubricant outlet orifice 77 of the closure plug 46 and emerge from the universal joint there.
The embodiment of the universal joint spider
17 illustrated in Figure 4 differs from the universal joint according to Figures 1-3 only inasmuch as the diameter of the central bores 60 and 61 is greater than the distance between the parallel planes 1 5 and 16, in which the axes 22-25 of diametrally opposed journals 1 8-21 are respectively oriented. By this choice of diameter of the two central bores 60 and 61, they automatically communicate at the central intersection point 62, so that there is no need for an additional connecting bore 79 as was provided in the universal joint according to Figures 1-3.
The external diameter of the tubes 67 and 68 in this case is at most equal to the mutual interval of the parallel planes 1 5 and 1 6. In other respects the universal joint according to this embodiment corresponds to the universal joint previously described, so that identical components have been designated by identical reference numerals. The
lubrication path for the one-way lubrication
connecting the bearing positions 11-14 is
likewise indicated by arrows in Figure 4. The
arrows extending outside the joint spider 1 7 represent the lubrication path through the
respective bearings 38-41. The lubrication path
is identical to that described with reference to
Figures 1 and 2.
The universal joint according to the invention is not restricted to the embodiments described
hereinbefore. It may particularly also be
constructed as a double joint, wherein two identical joint spiders 17, each with four bearing positions 11-14, i.e. eight bearing positions in all are present between the two drive shafts 58, 59.
In that case the so-called double drive joint exhibits two lubrication paths, each with four bearing positions connected by a lubrication path.
