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: 8622644Abstract: A seal assembly and method of forming a seal assembly provides a seal body having reduced strain during use, thereby increasing service life. The seal body may be formed within certain parameters, such as ranges of height-to-thickness and offset-to-height ratios, which have been found to reduce strain. Additionally or alternatively, the seal body may be modified from an initial configuration to a pre-strained configuration by axially displacing an inner section of the seal with respect to an outer section of the seal, which also reduces strain.Type: GrantFiled: April 21, 2011Date of Patent: January 7, 2014Assignee: Caterpillar Inc.Inventors: Dan J. Becker, Ross Paul Wietharn

Patent number: 8070143Abstract: A resilient mount including a first mounting member and a second mounting member is provided. The mount includes a first plurality of stiffening elements located between the first and second mounting members. At least a first stiffening element of the first plurality of stiffening elements is non-parallel to a second stiffening element of the first plurality of stiffening elements. Each of the first plurality of stiffening elements has a material thickness and an out-of-plane dimension that is greater than the material thickness. Each stiffening element of the first plurality of stiffening elements is substantially rigid so as to substantially limit the deformation of the stiffening element under load. The mount may also include a resilient material located between and coupled to adjacent stiffening elements of the first plurality of stiffening elements.Type: GrantFiled: February 14, 2007Date of Patent: December 6, 2011Assignee: Caterpillar Inc.Inventor: Ross Paul Wietharn
