Patent number: 9824953Abstract: A semiconductor module is disclosed. The semiconductor module may include a housing having a sidewall portion, a housing support plate coupled to a bottom surface of the sidewall portion such that the housing support plate and the sidewall portion define an interior space of the housing of the semiconductor module, and a semiconductor device disposed within the interior space and fixedly coupled to the housing. The semiconductor module may further include a cover member fixedly attached to a top surface of the sidewall portion such that the cover member, the housing and the housing support plate form a protective enclosure for the semiconductor device.Type: GrantFiled: May 16, 2016Date of Patent: November 21, 2017Assignee: Caterpillar Inc.Inventors: William Mische, Eric Andris, Basheer Qattum, Daniel Sergison

Patent number: 8393429Abstract: A motor grader with an adjustable wheelbase. The motor grader may include front and rear wheels supporting a chassis and a main frame. A working blade may downwardly depend from the main frame between the front wheels and rear wheels to perform work on the ground below. The motor grader may also provide an adjustable wheel base to allow the center of gravity of the motor grader to better match the work load being addressed. The adjustable wheel base may also provide more swing clearance for the blade relative to the rear wheels, allow for an adjustable articulation angle, and minimize structural loads on the motor grader, particularly during ripping operation. The wheel base may be adjustable by providing structure through which the relative positions of the rear wheels can be altered automatically, manually, and dynamically.Type: GrantFiled: November 3, 2010Date of Patent: March 12, 2013Assignee: Caterpillar Inc.Inventors: Norval Thomson, Steven Daniel, Daniel Sergison

Patent number: 8262125Abstract: A machine (100) includes a frame (102) portion and a tandem wheel arrangement, which includes a main linkage (312) and a stabilizing linkage (322) that are pivotally connected to the frame (102) portion. A first mount (304) and a second mount (304) are pivotally connected to the main linkage (312) and to the stabilizing linkage (322), such that the main linkage (312), the stabilizing linkage (322), the first mount (304), and the second mount (304) define a four-bar-linkage arrangement (202) that operates to transfer unbalanced torque loads from the first mount (304) and the second mount (304) to the frame (102) portion.Type: GrantFiled: October 13, 2010Date of Patent: September 11, 2012Assignee: Caterpillar Inc.Inventors: Daniel Sergison, Norval P.

Patent number: 8016068Abstract: A tandem drive arrangement includes one or more independently driven wheels (118) that are arranged in a tandem configuration along a beam (120). The beam (120) is rotatably connected to a frame (102) of a machine (100). The tandem drive arrangement further includes an actuator (206) operating to selectively impart a rotating moment to the beam (102). The rotating moment tends to rotate the beam (120) in one direction and counteracts a torque imbalance resulting from operation of motors (128) rotating one or more independently driven wheels (118) connected to the beam (120).Type: GrantFiled: October 23, 2008Date of Patent: September 13, 2011Assignee: Caterpillar Inc.Inventors: Steven A. Daniel, Norval P. Thomson, Daniel Sergison, John V. Mount

Patent number: 7832509Abstract: A machine (100) includes a frame that is pivotally connected to a tandem drive arrangement. The tandem drive arrangement includes a beam (120) and a first motor (128) having a first stator portion (202) connected to a first end of the beam (120). The first motor (128) also includes a first rotor portion (204) connected to a first drive wheel (118). A load sharing arrangement (412) is associated with the tandem drive arrangement and includes a first collar (414) rotatably disposed around the first stator portion (202) and a second collar (426) rotatably disposed around a portion of the beam (120). A first linkage (424) is pivotally connected between the first and second collars such that the load sharing arrangement (412) balances unbalanced loading in the tandem drive arrangement by transferring the unbalanced loading to the frame.Type: GrantFiled: July 16, 2008Date of Patent: November 16, 2010Assignee: Caterpillar IncInventors: Norval P.

Publication number: 20100050803Abstract: A manual control (200) includes a stem (206) having an elongate shape and a centerline. A grip (204) is pivotally connected to an end of the stem (206) at a pivot point (222), and a sensor array (226) is integrated with the grip (204). The sensor array (226) includes at least one sensor disposed to measure a pivotal displacement of the grip (204) relative to the stem (206). The grip (204) and the sensor array (226) are pivotal with respect to the stem (206) at the pivot point (222).Type: ApplicationFiled: September 3, 2008Publication date: March 4, 2010Applicant: Caterpillar Inc.Inventors: Robert L.
