20130206678 | FLUID FILTER SYSTEM - An endcap including a first plate member including a radial inner portion, a radial outer portion, and defining a longitudinal axis. The endcap also includes a flange disposed between the radial inner and outer portions of the first plate member and projecting axially along the longitudinal axis in a first direction. The endcap also includes a first seal member disposed adjacent the flange. The first seal includes a first portion thereof engaged with an axial facing surface of the first plate member and a second portion thereof engaged with a radially facing surface of the flange. The endcap further includes a second plate member disposed radially outward of the radial outer portion and a second seal member disposed adjacent the second plate member including at least a portion thereof axially spaced from the axially facing surface of the first plate member in a second direction along the longitudinal axis opposite the first direction. | 08-15-2013 |
20130213015 | EXHAUST SYSTEM THERMAL ENCLOSURE - An exhaust system for a power system contained in an engine compartment. The exhaust system includes a mount for two or more exhaust treatment devices and an enclosure surrounding the two or more exhaust treatment devices. The enclosure defines a space with a higher temperature than a space defined by the engine compartment during steady state operation of the power system. At least one electronic or fluid device is coupled to the enclosure or mount and located on an exterior of the enclosure. | 08-22-2013 |
20130219877 | System and Method for Calibrating Hydraulic Valves - A system and method for calibrating an electronically actuatable hydraulic valve in a work machine may include at least one supply valve and at least one drain valve to be calibrated and a bypass valve in fluid communication with a pump and a fluid source. The at least one supply valve and the at least one drain valve may be calibrated by opening the at least one supply valve and the at least one drain valve, closing the bypass valve, setting the pump to a desired flow output, determining a first current command for the at least one supply valve corresponding to a first target pressure parameter and determining a second current command for the at least one drain valve corresponding to a second target pressure parameter. | 08-29-2013 |
20130220114 | PISTON RETENTION APPARATUS AND METHOD - An apparatus and method for coupling a piston to a rod to form a cylinder assembly are provided. The piston has a tapped bore extending therethrough for coupling to a first threaded region of the rod. The rod end extends beyond the piston member and includes a second threaded region for coupling to a tapped bore of a retaining member. The piston member is coupled to the rod member at a low torque, e.g., up to about 1000 Nm. An external thread of each of the threaded segment of the piston bore and the first threaded region of the first portion of the rod member may be formed with a root radius of greater than 0.125 pitch or with MJ class thread. The retaining member may include setscrews offset from one another for frictional engagement with the rod end. The thread pitch between the rod and the piston may be coarser than between the rod and the retaining member. An interface and a seal region between the rod and the piston may be disposed closer to the rod end side of the piston member than the threaded coupling. | 08-29-2013 |
20130221739 | Abrasion Resistant Track Shoe Grouser - A track shoe for a track-type vehicle. The track shoe includes a base plate and a grouser projecting away from the base plate. A capping surface structure of substantially horseshoe shaped cross-section is disposed across a distal portion of the grouser. The capping surface structure covers portions of a distal edge surface and adjacent lateral surfaces. The capping surface structure is formed from an material characterized by enhanced wear resistance relative to portions of the grouser underlying the capping surface structure. | 08-29-2013 |
20130223930 | Oscillatory Compaction Method - A method for compacting a surface of granular materials is disclosed. The method is applicable to wheeled compaction equipment such as pneumatic-tire compactors, drum-type compactors and asphalt compactors. The propel system includes a controller programmed to send a first at least substantially constant propel command that propels the compaction equipment in a forward direction. The controller then changes the speed of the compaction equipment by providing a second varying propel command that may increase or decrease the speed resulting from the first command. As a result, the speed of the compaction equipment oscillates, and the compaction process is improved. | 08-29-2013 |
20130317707 | IMPLEMENT CONTROL SYSTEM FOR A MACHINE - This disclosure relates to a control system for a machine implement. The control system includes a measurement sensor configured to provide an implement measurement signal indicative of a velocity of a machine implement, and a controller. The controller is configured to provide an implement measurement signal and an operator command signal, and to determine an adjusted implement command based signal based on the implement measurement signal and the operator command signal. | 11-28-2013 |
20140260198 | EXHAUST AFTERTREATMENT SYSTEM - An exhaust aftertreatment module is provided. The exhaust aftertreatment module includes a housing having a first end and a second end. The at least one inlet is disposed between the first end and the second end and is configured to introduce an exhaust into the housing. A mixing tube is disposed downstream of the at least one inlet. The mixing tube is configured to direct the exhaust towards the second end of the housing. The exhaust aftertreatment module further includes a single bank of Selective Catalytic Reduction (SCR) catalysts disposed at an oblique angle to a longitudinal axis of the mixing tube. The single bank of SCR catalysts is configured to receive the exhaust redirected from the second end of the housing. | 09-18-2014 |
20140334685 | MOTION ESTIMATION SYSTEM UTILIZING POINT CLOUD REGISTRATION - A system and method of estimation motion of a machine is disclosed. The method may include determining a first point cloud and a second point cloud corresponding to an environment in a vicinity of the machine. The method may further include generating a first extended gaussian image (EGI) for the first point cloud and a second EGI for the second point cloud. The method may further include determining a first EGI segment based on the first EGI and a second EGI segment based on the second EGI. The method may further include determining a first two dimensional distribution for points in the first EGI segment and a second two dimensional distribution for points in the second EGI segment. The method may further include estimating motion of the machine based on the first and second two dimensional distributions. | 11-13-2014 |
