Patent number: 9897158Abstract: An isolation mount assembly comprises a resilient member defining a central aperture that defines a load axis and an annular depression about the load axis, and an adapter plate including an outer mechanical attachment structure that defines a first thickness and an inner attachment structure that is closer to the load axis than the outer attachment structure along a direction that is perpendicular to the load axis and that defines a second thickness. The inner attachment structure is disposed in the annular depression and the second thickness is at least twice the first thickness.Type: GrantFiled: June 29, 2016Date of Patent: February 20, 2018Assignee: Caterpillar Inc.Inventors: Brett D. Ellen, Daniel Joshua Smith, Wen Zhong, Hong Lian, Matt Schwarzendruber, Ross Paul Wietharn, James D. Neirynck

Patent number: 9771030Abstract: A mounting system for an electronic control module is disclosed. The mounting system includes a first mounting member, a second mounting member, and a third mounting member coupled to the first mounting member and the second mounting member by a plurality of first isolation devices and by a plurality of first fastening members. The third mounting member includes a base portion having a first end and a second end. The base portion is coupled to the ECM by at least one second isolation device and by at least one second fastening member. The third mounting member includes a first leg portion coupled to the first mounting member. The third mounting member further includes a second leg portion coupled to the second mounting member.Type: GrantFiled: May 24, 2016Date of Patent: September 26, 2017Assignee: Caterpillar Inc.Inventors: Terry L.

Patent number: 8682539Abstract: A machine employing controllable mounts and a method for controlling such mounts based on machine operation are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so are the damping and stiffness properties of the controllable mount. With other operations such as roading or working on a flat surface, the feedback afforded by the mounts is not as important as operator comfort, in which case the current applied to the coils can be lowered and thus the mount can be made more relaxed. The machine of the present disclosure identifies the machine operation being performed through sensors, predictive algorithms, implement position, and operator input and sets the current and properties of the controllable mounts accordingly.Type: GrantFiled: December 14, 2009Date of Patent: March 25, 2014Assignee: Caterpillar Inc.Inventors: Steven D. Jones, Ronald B. Warnat, Brett D. Ellen, Nathan S. Pauli, Michael S. Contratto

Patent number: 8678478Abstract: A machine includes a frame and an operator cab supported by the frame. One or more passive mounts and one or more controllable mounts operatively connect the operator cab to the frame. The one or more controllable mounts include a housing, a pin mounted within the housing, a rheological fluid within the housing, and coils positioned relative to the housing to generate a field through the rheological fluid. An electronic control unit operatively associated with the coils and adapted to change a level of current applied to the coils to adjust an apparent viscosity of the rheological fluid to actively change the damping characteristics of the one or more controllable mounts.Type: GrantFiled: December 14, 2009Date of Patent: March 25, 2014Assignee: Caterpillar Inc.Inventors: Steven D. Jones, Brett D. Ellen, Ronald B. Warnat, Kevin D. Ehrenhardt

Publication number: 20100152979Abstract: A machine employing controllable mounts and a method for controlling such mounts based on machine operation are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so are the damping and stiffness properties of the controllable mount. With certain machine operations such as fine grading, plowing and loading, this may be helpful to the operator to more quickly or effectively perform the given task. With other operations such as roading or working on a flat surface, the feedback afforded by the mounts is not as important as operator comfort, in which case the current applied to the coils can be lowered and thus the mount can be made more relaxed.Type: ApplicationFiled: December 14, 2009Publication date: June 17, 2010Applicant: CATERPILLAR, INC.Inventors: Steven D.

Publication number: 20100152978Abstract: A machine employing controllable mounts and a method for controlling such mounts to maintain ideal snubbing height and provide mount diagnostics are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. The pin may be held in the housing with a limited degree of play by an elastomeric member and in so doing hold the pin at the ideal snubbing height. Over time the elastomeric member may degrade and begin to sag. Sensors associated with the housing may monitor this sag and if necessary energize a field across the rheological fluid or pressurize gas within the housing so as to adjust to the position of the pin back to the ideal snubbing height. The data gathered by the sensors can also be stored and used to determine the remaining serviceable life of the controllable mount and diagnose when it should be replaced.Type: ApplicationFiled: December 14, 2009Publication date: June 17, 2010Applicant: CATERPILLAR, INC.Inventors: Steven D.

Publication number: 20100152980Abstract: A machine employing controllable mounts and a method for controlling such mounts based on machine location are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so is the stiffness of the controllable mount. Depending on machine location, however, the operator may want differing levels of stiffness in one or more of the controllable mounts. For example, when roading on rocky terrain, the operator may want relatively loose mounts so as to absorb the large vibration inputs and make for a more comfortable ride.Type: ApplicationFiled: December 14, 2009Publication date: June 17, 2010Applicant: CATERPILLAR, INC.Inventors: Steven D.
