Filed:

Mar 16, 2011

Appl. No.:

13/048960

Inventors:

Jason J. Weber - Peoria IL, US
John B. Salomon - Peoria IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

F16H 48/06

US Classification:

475230

Abstract:

A shroud assembly and method for assembling such shroud assembly for a vehicle are disclosed. The shroud may comprise a collar joined to a nose cap. The shroud assembly may comprise the collar, the nose cap, and meshed ring and pinion gears. The collar may define at least one port and the nose cap may define an aperture. These allow lubricating fluid to escape outside of the shroud and thus be removed from the immediate vicinity of the rotating ring and pinion gears.

International Classification:

F16H 57/04

US Classification:

475160

Abstract:

A drive axle housing system may minimize churning of splash and spray oil within a drive axle housing. The drive axle housing system includes apparatus for incorporation into the axle, the apparatus including an oil churning reduction member that may be affixed to the interior walls of the axle housing. The oil churning reduction member includes interior surfaces adapted to closely align with interior moving gear components of the axle to minimize efficiency losses due to oil movement. The system may also incorporate an annular element, affixed to the axle housing and closely aligned with the backside of a ring gear component of the differential axle. The combined use of the member and the element may substantially reduce torque losses attributable to excessive churning of oil.

International Classification:

F16H 1/12
B23P 11/00

US Classification:

74417, 298931

Abstract:

An axle assembly and method for assembling such axle assembly for a vehicle are disclosed. The axle assembly may comprise meshed ring and pinion gears, a center housing portion, and left and right leg housing portions. The center housing portion may include a center housing defining a center cavity in which the bevel gear is disposed, and at least one channel having an entrance port into the center cavity. The axle assembly may include a first conduit configured to branch off of the first channel in a first direction and a second conduit configured to branch off of the first channel in a second direction. Such channels and conduits may be integral to the center housing or substantially external to the center housing.

Abstract:

A pump monitoring and notification system for a hydraulic pump includes a transmission speed sensor and a controller. The transmission speed sensor is associated with a transmission connected to the pump to determine an output speed of the transmission. The controller is configured to access a transmission threshold, access a time threshold, and determine a rotational speed of the transmission based upon the transmission speed sensor. The controller is further configured to determine a variation in rotational speed of the transmission based upon the rotational speed, compare the variation in rotational speed of the transmission to the transmission threshold, and generate an alert signal when the variation in rotational speed of the transmission exceeds the transmission threshold for a time period exceeding the time threshold.

International Classification:

F16H 57/04
B60B 35/16

US Classification:

301137, 298931

Abstract:

A machine axle housing includes a central body having an oil reservoir and a pair of axle legs. The central body includes a ring gear, an oil channel, and oil port for conveying oil through an oil conduit to each leg. Machine brakes within the central body include at least one disc rotatably adapted to centrifugally move oil radially outwardly of the brakes. A second oil channel collects oil from the disc, and a passageway extends from the second oil channel back to the central body to return oil from the legs back to the central body. The ring gear, first oil channel and first oil conduit define a first oil lubrication sub-system for moving oil from the central body to right and left legs, and the disc, second oil channel, and passageway define a second oil lubrication sub-system for moving oil from the legs back to the central body.
