Definitions

  • This invention relates to joint connections employed in the link assembly of a track- type vehicle and a method for assembling the joint connections.
  • FIG. 19 of this patent discloses a cup-shaped member 43h disposed between a pin and link.
  • welds are required to secure the pins and link together, thus giving rise to the above problems.
  • the present invention is directed to overcome one or more of the problems as set forth above.
  • 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.
  • 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.
  • 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.
  • a method 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.

  • FIG. 5 is a partial view, illustrating another modification of the locking collar and joint connection.
  • FIG. 6 is a partial view illustrating still another modification of the locking collar and joint connection.

  • 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.

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.

Abstract

L'utilisation de chenilles pour vehicule du type a chenille pose le probleme de la chasse des tiges dans la connection des joints. Cette chasse des tiges resulte essentiellement des charges importantes qui sont imposees a la connection des jointures pendant le fonctionnement des assemblages des chenilles. Un collier de verrouillage (17) est fixe entre la tige (16) et un maillon (14) d'un assemblage de chenille (10) pour empecher une telle chasse des tiges. En particulier, la tige (16) et le collier de verrouillage (17) ont des surfaces cooperantes (22, 23) pour empecher leur mouvement axial relatif. En appliquant ce procede, des segments (20) du collier de verrouillage (17) montes sur la tige (16) et le maillon (14) est alors fixe au collier de verrouillage (17).
