Appl. No.:

09/570860

Inventors:

Roy V. Brookhart - Cary NC
Scott E. Keele - Cary NC
J. Brian Normann - Holly Springs NC
Kevin J. Romanchok - Holly Springs NC

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

E02F 376

US Classification:

37442, 37444, 37231, 37234, 172825, 414697, 414723

Abstract:

A tiltable bucket assembly includes a bucket and an interface member. The bucket has a front loading portion, a rear connecting portion with a front surface adjacent the front loading portion and a rear surface opposite therefrom, and a pair of spaced guide members connected to the rear surface. The bucket defines a substantially enclosed chamber that extends from the front surface and terminates within the front loading portion. The interface member is rotatably mounted with the bucket. The interface member has opposed side portions supported within the guide members. A hydraulic cylinder is located within the chamber and has a rod end portion connected to the bucket and a head end portion connected to the interface member. The hydraulic cylinder is adapted to provide rotational movement of the bucket about the interface member upon actuation.

International Classification:

B62D 55/21
F16C 33/14
B23K 9/04
B23K 26/342

Abstract:

A steel track chain component, such as a track bushing, may be formed with a carburized portion, a hardface portion, and a core portion. The core portion may be softer than the carburized portion, which in turn, may be softer than the hardface portion. This configuration of the various portions of the component may allow for relatively high wear resistance of the component, as well as toughness. The core portion may be mostly ferrite crystal structure, while the carburized portion and the hardface portions may include martensitic and/or austenitic crystal structure. The carburized portion may be formed by carburizing the track chain component in a heated and carbon rich environment. The hardface portion may be formed by welding a hardface alloy over at least a portion of the carburized portion.

International Classification:

C21D 9/00
B62D 55/21

Abstract:

An example bushing has three portions along its radial direction including an inner portion most proximal to a central hole of the bushing, an outer portion most distal from the center hole, and a core portion between the inner portion and the outer portion. The core portion has a hardness that is less than the hardness of the inner portion or the outer portion of the bushing. The bushing may be formed using high carbon steel, which in some cases may be spheroidal cementite crystal structure. A rough bushing may be formed using the high carbon steel, followed by a direct hardening process, and an induction hardening process on the inner surface most proximal to the central hole of the bushing. The induction hardening on the inner surface may harden the outer portion while tempering the core portion of the bushing.

International Classification:

B62D 55/21
B21K 23/02

Abstract:

A bushing assembly for a track assembly includes a first end element, a second end element, and a central element positioned between the first end element and the second end element. The central element may be interference fit or positioned between the first end element and the second end element, and the central element may include a greater hardness than the first and second end elements. The first end element, the second end element, and the central element form a bushing with a longitudinal opening extending longitudinally through the bushing.
