Abstract

A recurring problem encountered with the use of track assemblies for track-type vehicles is one of preventing pin drift in the joint connection therefor. Such pin drift primarily results from the severe loads which are imposed on the joint connection during operation of the track assemblies. This invention provides a locking collar (17) which is secured between a pin (16) and a link (14) of a track assembly (10) for preventing such pin drift. In particular, the pin (16) and locking collar (17) have interengaging surfaces (22, 23) formed thereof to prevent relative axial movement therebetween. In carrying forth the method steps of this invention, segments (20) of the locking collar (17) are mounted on the pin (16) and the link (14) is then secured to the locking collar (17).

Description

Description
TRACKJOINTLOCKINGCOLLARANDASSEMBLYMETHOD
Technical Field This invention relates to joint connections employed in the link assembly of a track- type vehicle and a method for assembling the joint connections.
Background Art Track assemblies employed on heavy-duty- track-type vehicles, such as track-type tractors, are subjected to severe loading during operation thereof. Such loading is imposed on the joint connections of the track assemblies and, in particular, each track pin and link thereof. As a result, the standard press-fit relationship between the links and pins may tend to loosen to create end- play or "drift" of the pin whereby the integrated joint connection is loosened to create undue wear and related problems.
In addition, standard track joints are normally sealed and lubricated to increase the service life thereof. Loosening of the joint connections will tend to adversely affect such sealing, thus reducing the expected service life of the track assembly. One solution to this problem would be to weld or otherwise secure the pins to the links or the bushings disposed between the respective pins and links. However, since the track assembly must be periodically disassembled for repair or replacement purposes, this approach has not proved acceptable. In addition, heat created during welding could adversely affect the elastomeric seals normally employed in the joint connections.
Attention is directed to U.S. Patent No. 3,717,389, issued on February 20, 1973 to Roger L. Boggs et al. and assigned to the assignee of this invention. FIG. 19 of this patent discloses a cup-shaped member 43h disposed between a pin and link. However, welds are required to secure the pins and link together, thus giving rise to the above problems.
Disclosure of Invention
The present invention is directed to overcome one or more of the problems as set forth above.
In one aspect of this invention, a joint connection comprises a link having a bore and a pin mounted in the bore. A collar is disposed between the link and pin and locking means are provided for interengaging surfaces of the pin and collar for preventing relative axial movement therebetween.
In another aspect of this invention, the joint connection is employed in a track assembly of a track-type vehicle wherein the track assembly comprises a plurality of laterally spaced pairs of links with a pin connecting each pair of links together.
In still another aspect of this invention, the track pin locking collar comprises at least two separable segments having arcuate surface means, defined internally on the segments, for locking the collar within an annular groove defined on the track pin to prevent relative axial movement therebetween.
OMPI .. IPO In still another aspect of this invention, a method is provided for locking the track pin against axial movement relative to the link of the endless track assembly by mounting the separable segments of the collar about the pin and securing the link to the collar.
The locking collar and method of this invention thus provide for the expeditious formation of the joint connection which finds particular use in the track assembly of a track-type vehicle, whereby relative axial movements between the link and pin is prevented. This arrangement will thus isolate any seal employed in the joint connection against distortion thereof to provide a sealed and lubricated joint connection having a long service life.

Other objects and advantages of this invention will become apparent from the following description and accompanying drawings wherein:
FIG. 1 is a longitudinal, sectional view of a joint connection embodiment of the present invention employed in a track assembly of a track- type vehicle; FIG. 2 is an isometric view of a pair of segments of a locking collar employed in the joint connections;
FIG. 3 is a partial view, similar to FIG. 1, but illustrating a modification of the locking collar;
FIG. 4 is an isometric view similar to FIG. 2, illustrating the modified locking collar;
FIG. 5 is a partial view, illustrating another modification of the locking collar and joint connection; and
FIG. 6 is a partial view illustrating still another modification of the locking collar and joint connection.
5 Best Mode For Carrying Out The Invention
FIG. 1 partially illustrates an endless track assembly 10 including a pair of joint connections 11 for pivotally interconnecting an adjacent pair of track shoes 12 (one shown)
10 together. Although joint connections 11 are particularly adapted for application to a track assembly of a track-type vehicle, such as a tractor, it should be understood that such connections have broader applications wherein it is desired to form
15 an articulated chain, such as a track link assembly. In the illustrated track assembly embodiment, a pair of first track links 13 of a link assembly are bolted or otherwise suitably secured to one track shoe (not shown) whereas a pair of second, identical
20 track links 14 are likewise secured to a second, adjacent track shoe 12.
Track links 13 are press-fitted onto a bearing bushing 15 which is pivotally mounted on a pin 16. Each joint connection 11 comprises an annular
25 locking collar 17 defining an outer substantially continuous cylindrical surface 18 thereon which is press-fitted within an inner cylindrical surface 19 which defines a bore through link 14. Referring to FIG. 2, each collar 17 preferably includes a pair of
30. identical semi-cylindrical segments 20 extending circumferentially 180° to form one-half of composite collar 17. As shown in FIG. 1, each end 21 of pin lβ has an annular recess or groove 22 formed thereon, preferably taking the shape of a hyperboloid which is concave when viewed in longitudinal cross-section.
Upon assembly of segments 20 on pin 16, collar 17 will define a similar, but convex, hyperboloid-shaped inner surface 23 to thus provide a locking means 24 for interengaging with surface 22 for preventing relative axial movement between the collar and pin. An annular bearing bushing 25 is disposed axially between an inboard surface 26 of collar 17 and an outboard surface 27 of bearing bushing 15 to cooperate with locking means 24 to retain the surfaces at a set axial distance relative to each other. This axial disposition of surfaces 26 and 27 provides an annular space for seating a standard elastomeric ring seal 28 therein which functions to seal out contaminants from the pivotal bearing contact between bearing bushing 15 and pin 16.
A standard joint connection would find link 14 press-fitted directly onto a cylindrical end of a pin (collar 17 would be eliminated) whereby the circumference defining the press-fit relationship between the link and pin would be substantially less than that provided by the press-fit relationship defined by the larger circumference at interfacing surfaces 18 and 19 of collar 17 and link 14, respectively. The latter, larger circumference will thus provide substantially large surface areas for securing collar 17 and link 14 in press-fit relationship relative to each other. Furthermore, locking means 24 provides for the precise and continuous axial positioning of thrust bearing surfaces 26 and 27 relative to each other to not only prevent any drifting of pin 16, but to also provide for precise accommodation of seal 28 in joint connection 10.
FIGS. 3 and 4 illustrate a modification of joint connection 11. As shown, collar 17 of FIG. 3
OMPI essentially differs from collar 17 of FIG. 1 in that an annular flange 29 is formed on an inboard side thereof. A counter-bore 30 is thus defined within collar 17 to accommodate seal 28 therein. FIG. 4 illustrates a pair of matching segments 20, constituting collar 17.
FIGS. 5 and 6 illustrate modifications of locking means 24 wherein corresponding constructions are depicted by identical numerals, but wherein numerals depicting modified constructions in FIGS. 5 and 6 are accompanied by an "A" and a "B, " respectively. In FIG. 5, a pin 16 has a frusto- conically shaped surface formed on a modified end 21a thereof to define a recess or groove 22a thereon. An inner surface 23a of split two-piece collar 17 is shaped in a like manner for disposition within groove 22a to provide locking means 24 for preventing relative axial movement between pin 16 and collar 17. In FIG. 6, locking means 24 comprises a plurality of radial flanges formed on pin 16 to define outer surfaces 22b thereon which engage within annular grooves or recesses 23b, defined internally on split collar 17.
Industrial Applicability
Referring to FIG. 1, joint connections 11 are particularly adapted for use in track assembly 10 of a track-type vehicle, but may find other applications as will be appreciated by those skilled in the arts relating hereto. In particular, such joint connection may prove useful to one who is confronted with the problem of providing a joint connection wherein a pin and link must be secured together to provide the above- discussed disederata, including the prevention of relative axial movement therebetween.
OM In assembling the FIG. 1 joint connections 11, bushing 15 and links 13 would be installed on pin 16, whereafter thrust bearing 25 and seals 28 would be thrust bearing 25 is mounted in leak-tight, press-fit relationship on pin 16 and thrust ring 25 is firmly seated on the thrust ring to prevent oil leakage thereby. Thereafter, split locking collar of pin 17, including segments 20, would be mounted on end 21 of pin 16 and link 14 would be press-fitted onto the collar. The axial space accommodating seal 28, between surfaces 26 and 27, will thus be precisely defined and during operation of the track assembly locking means 24 will function to maintain such accommodation.
In addition, the relatively large surface areas effecting the press-fit relationship at surfaces 18 and 19 of collar 17 and link 14, respectively, will prevent any relative drifting between pin 16 and collar 17 during operation of the track assembly.
The FIGS. 3-6 embodiments may be assembled and will function in a like manner.
Other aspects, objects and advantages of this invention can be obtained from a study of the drawings, the disclosure, and the appended claims.
