Description
BEA~ING LUBRICATION ~OR SPINDLES IN VEHICLES
Back~round of the Invention Technical Field:
This invention relates to portions of vehicle wheel suspen-sions incorporating housings in which drive spindles are positioned by roller bearings in spaced bearing races.
Description of the Prior Art:
Prior structures of this type usually position roller bearing assemblies in spaced relation to one another and to the means for supplying lubricant thereto. See for example U.S. Patents 1,927,511 of June, 1932 to F. Wood, 2,191,876 of March, 1939 to C.A. Brotherton, 2,514,799 of July, 1950 to L. Rubertino et al., 4,172,620 of October, 1979 to M. Marti, 4,282,949 of Aug.11, 1981 to L.F. Kopich et al. and 4,427,089 of January, 1984 to J.G. Peterson. In each of these patent disclosures, spaced roller bearing assemblies in housings rotat-ably supporting shafts positioned therethrough are disclosed and in each instance, no means in provided for supplying lubricant directly to the roller bearings in the bearing race assemblies.
In Patent 1,927,511, oil as a lubricant must find its way through the sides of the bearing races with the result that the major portion of the roller bearings are not lubricated.
In Patent 2,191,876, radial bores in the spindle communicate with longitudinal bores therein and -terminate in spaced relation to -the outer sides o~ the bearing races in which -the roller bearings are mounted so tha-t the majority of the wear surfaces of the roller bearings are no-t lubricated.
In Patent 2,514,799, a drilled disc is positioned adjacent one o the ball bearing races for extremely limited communication with the sides of the races resulting in the ball bearings running dry.
In Patent 4,172,620, lubricant is delivered through grease fittings to an annular area at one side of the circular bearing races which remain largely unlubricated.
In Patent 4,282,949, lubricant is theoretically delivered to a small annular area adjacent the sides of the bearing races in which roller bearings are positioned with the result that the bearing races remain unlubricated, and in Patent 4,427,089, lubricant passageways formed in king pins 58 attempt to lubricate bearings in spaced races positioned in isolated relation to the lubricant passageways.
This invention provides lubricant openings directly in 1Z5344~.
a housing and in bearing races therein insuring delivery of the lubricant through the bearing races and directly to roller bearings and their wearing surfaces engaging the bearing races.
Summarv of the Invention A vehicle suspension incorporating a drive spindle rotatably positioned on roller bearings in bearing races in a housing having integral support arms is improved by the addition of lubricant delivering passageways extending through the housing in accessible locations and extending through the bearing races so as to communicate direc-tly with the roller bearings therein for the effective delivery of lubricant directly to the bear-ings and their wearing surfaces engaging the bearing races.
Descri~ion of the Drawin~s Figure 1 is a vertical section through a drive spindle in a housing of a vehicle suspension showing the lubricant delivering passageways; and Figure 2 is a side elevation of the drive spindle illustra-ting a brake flange and dust shields positioned on the housing and 12531~4~1tt 'Vl~ t l~ " 111~ v~t l ~ t l~ l) l V I tl l ()ll (t l' W¦llllll 11 111' i Vt) tlllll 1 1, l~i lliillll I I V l`(lllllt?l`l.t111 1111 ~vl I :1 1111 Illlllltl :11~11111 +(I`I`~ tlll~l ~`li 4~
drive spindle lL extends and a second shield 16 is positioned about a brake flange 17 mounted on the housing 10, studs 17' on the bral~e flange movably support brake shoes (not shown).
Still referring to Figure 2 of the drawings, it will be seen that a lubricant fitting 18 is positioned on the upper portion of the housing 10 in oppositely disposed relation to said support arms 11 and immediately adjacent the first shield 15 in a location where a grease gun or the like can readily engage the fitting and that a second lubricant fitting 10 19 is positioned on the lower surface of the housing 10 on the opposite side thereof with respect to the lubricant fitting 18 and is located in a position where it is readily accessible by a grease gun or the like.
By referring now to Figure 1 of the drawings, a vertical 15 section through the housing 10 illustrated in Figure 2 of the drawings and heretofore described will be seen and it will be observed that the lubricating fitting 18 is threadably mounted in a passageway 20 extending through the housing 10 in direct registry and communication with a passageway 21 20 in a portion 22 of an outer bearing race having a second portion 23. A plurality of circumferentially spaced roller bearings 24 are positioned between the annular bearing ràces 22 and 23, 125344~
the bearings 2~ being preferably tapered roller bearings. The portion 22 Or the outer bearing race is seated in an annular inner recess in the housing 10 and against a shoulder, the portion 23 of the outer bearing race is seated on the drive spind]e 12. A bearing spacer 26, which is tubular in configuration, is positioned on the drive spindle 12 in engagement with the portion 23 of the outer bearing race just described and spaces a portion 27 of an inner bearing race having a plurality of roller bearings 28 arranged in circumferentially spaced relation thereon and engaging a portion 29 thereof which iD turn is positioned in an annular recess in the inner wall of the housing lO against a shoulder.
It will be seen that the bearing races mounting the roller bearings 24 and 28 are spaced with respect to one another and that the tapered roller bearings 24 and 28 are angularly disposed with respect to one another and the axial cen-ter line of the drive spindle 12.
Still referring to Figure 1 of the drawings, it will be seen that the second lubrica~ing fitting 19 is threadably engaged in a secondary passageway 30 in the housing 10 in subs-tantially oppositely disposed and spaced relation with respect to the rirst mentioned passageway 20 and that the secondary passageway 30 regis-ters with and communica-tes with a passageway 31 in the annular portion 29 of the outer bearing race in which the tapered roller bearings 28 are disposed.
I-t will thus be seen that the provision of the lubricant fittings 18 and 19 arld their communicating lubricant passageways 20 and 30 respectively extending through the walls of the housing 10 establish direct communication with the passageways 21 and 31 respectively in the bearing races of the outer and inner bearing assemblies respectively.
The arrangement is such that a lubricant such as delivered by a grease gun or the like to the accessible lubricant fitting 18 and 19 will be delivered directly to the surfaces of the tapered roller bearings 24 and 28 and the inner opposed surfaces of the portions 22 and 23 of the inner bearing and the portions 27 and 29 of the outer bearing assembly. An annular chamber C spaces the bearing races.
Most importan-tly, the provision of the lubricant fittings 18 and 19 and the communicating passageways just ~2S,344~
described enable the bearing assemblies on which the drive spindle 12 is rotatably carried to be lubricated periodically and avoid the wear which has resulted in the need of replacing the drive spindle and housing assemblies in many motor vehicles.
The invention comprises the combination of the housing 10, the outer bearing races and the communicating lubricant passage-ways therein and the lubricant fittings which make possible the rebuilding of the worn drive spindles and housings including the housing support arms, which at the present time is the only method of insuring the continued lubrication of these important bearing assemblies on the drive spindles of the motor vehicles using the same.
Having thus described my invention, what I claim is:
