  • Patent number: 11964711
    Abstract: A track link for a ground-engaging track system includes a link body having a pin bore formed in a first link strap and a bushing bore formed in a second link strap. The link body includes, upon an outboard link side, a bore peripheral surface extending circumferentially around a bore center axis, and a guide protrusion including an outer bump surface located outboard of the bore peripheral surface. The pin bore receives a track pin attached by swaging and defines a diametric plane through the bore center axis oriented parallel to an upper rail surface. At least a majority of the outer bump surface is between the diametric plane and the upper rail surface, and an entirety of the outer bump surface may be between the bore center axis and the upper rail surface. The guide protrusion protects material of the track link and/or track pin from wear that can prevent re-swaging.

  • Patent number: 9868482
    Abstract: A roller of an undercarriage track system for a machine is disclosed. The roller includes a body and a sensed feature. The body is a solid of revolution formed about a roller axis. The body includes a bore surface and a roller contact surface. The bore surface defines a bore extending through the body. The bore surface is a radially inner surface of the body. The roller contact surface is located outward from the bore surface. The sensed feature is located at the body. The sensed feature is configured to rotate with the body and to be detectable by a sensor.

  • Patent number: 9557244
    Abstract: A thrust bias detection system for a mobile machine is disclosed. The mobile machine may have a first track assembly and a second track assembly. The thrust bias detection system may have a first wear sensor configured to generate a signal indicative of a first wear measurement of a first track link surface, and a second wear sensor configured to generate a signal indicative of a second wear measurement of a second track link surface. The thrust bias detection system may also have a controller in communication with the first and second wear sensors and configured to determine whether at least one of the first and second track assemblies has experienced thrust bias, based on the signals.
