Publication number: 20240247699Abstract: An elastomeric bushing includes an inner sleeve, a travel limiter disposed around the inner sleeve, an elastomeric bumper disposed around and directly engaging the travel limiter, and an outer sleeve disposed around the inner sleeve, the travel limiter and the elastomeric bumper. The outer sleeve is spaced apart from the inner sleeve and directly engages the elastomeric bumper. The travel limiter includes a radially outwardly extending first protrusion and a diametrically opposed radially outwardly extending second protrusion. A first portion of the elastomeric bumper is bounded by a first reduced diameter portion of the outer sleeve and the first and second protrusions. A second portion of the elastomeric bumper is bounded by a second reduced diameter portion of the outer sleeve and the first and second protrusions. The elastomeric bumper includes diametrically opposed voids axially extending therethrough. The voids are circumferentially rotated relative to the first and second protrusions.Type: ApplicationFiled: January 20, 2023Publication date: July 25, 2024Inventor: Scott W. RAWLINGS

Patent number: 11378152Abstract: A hydraulic bushing assembly comprises an inner tube, a travel limiter surrounding the inner tube, a first intermediate insert, a second intermediate insert spaced apart from the first intermediate insert, and an elastomeric bushing disposed around the inner tube and encapsulating the first intermediate insert and the second intermediate insert. The elastomeric bushing at least partially encapsulates the travel limiter such that a portion of the elastomeric bushing is positioned between the travel limiter and the inner tube. First and second snubbers limit displacement of the travel limiter and define first and second fluid chamber within the elastomeric bushing. A fluid passageway defined by the elastomeric bushing and an outer tube extends between the first and second fluid chambers, wherein relative movement between the inner tube and the outer tube causes fluid transfer between the first fluid chamber and the second fluid chamber.Type: GrantFiled: December 18, 2020Date of Patent: July 5, 2022Assignee: The Pullman CompanyInventors: Zoren E.

Patent number: 11009097Abstract: A hydraulic mount includes an inner tubular assembly, first and second elastomeric bodies and a fluid-track. The first and second elastomeric bodies are attached to the inner tubular assembly and cooperate to define a first fluid chamber. The second elastomeric body also defines a second fluid chamber that is in fluid communication with the first fluid chamber via the fluid-track. The fluid-track is attached to the inner tubular assembly partially disposed in the first fluid chamber. The fluid-track includes a central portion, a peripheral portion and a passage. The peripheral portion extends radially outwardly from a periphery of the central portion. The passage provides fluid communication between the first and second fluid chambers. Gaps are positioned between the peripheral portion and a wall of one of the first and second elastomeric bodies.Type: GrantFiled: January 31, 2019Date of Patent: May 18, 2021Assignee: The Pullman CompanyInventors: Scott W.

Patent number: 10752293Abstract: A body mount comprises a first support member defining a first support surface adapted to engage a body of a vehicle. A second support member includes a second support surface adapted to engage a frame of the vehicle. A connector member is positioned between a cover and the second support member. The connector member includes a channel support including a channel having an inlet and an outlet. A central member is fixed to the first support member and moveable relative to the second support member. The cover and the connector member define a first chamber. The connector member and the second support member define a second chamber. The chambers are fluidly connected via the channel. The channel circumferentially extends about the central member. Movement between the central member and the second support member causes fluid to travel through the inlet, channel, and outlet to transfer fluid between the chambers.Type: GrantFiled: May 6, 2019Date of Patent: August 25, 2020Assignee: The Pullman CompanyInventor: Scott W.

Patent number: 9976620Abstract: The present disclosure is directed to a bushing assembly having a tubular inner metal, a tubular outer metal, a tubular rigid cup disposed over an outer portion of the tubular inner metal, and a tubular pad disposed between the tubular rigid cup and the tubular outer metal. The tubular pad may have a first wall section and a second wall section at least partially circumscribing the first wall section. The first wall section may be configured to be compressed and to expand along an axis parallel to an axial center of the tubular pad, to thus fill the tubular rigid cup and enhance a stiffness of the bushing assembly when the tubular outer metal of the bushing assembly is moved towards a limit of a range of radial travel.Type: GrantFiled: September 9, 2016Date of Patent: May 22, 2018Assignee: The Pullman CompanyInventors: Scott W.
