Patent number: 9139045Abstract: A non-pneumatic tire comprising one or more radial regions have differing Shore A/Shore D hardness. The non-pneumatic tire comprises side cavities that are staggered with respect to laterally opposing side cavities, and laterally extending tread grooves that are in substantial radial alignment with or substantially offset relative to the cavities. One radial region may comprising the side cavities, while another radial region with a different hardness comprises the tread grooves. Also provided are processes for making such tires and to off-the-road (OTR) vehicles employing such tires.Type: GrantFiled: November 6, 2008Date of Patent: September 22, 2015Assignee: Chemtura CorporationInventors: Richard L.

Publication number: 20120234444Abstract: A non-pneumatic tire is provided with an annular reinforcing web that reduces the bending of compression spokes formed in the tire and reduces stresses and strains in the tire. The non-pneumatic tire includes an inner hoop member having an inner surface that defines the inner diameter of the tire, and an outer hoop member having a tread groove region that defines the outer diameter of the tire. A disc-shaped central web portion connects the inner and outer hoop members. A plurality of elongated, radially aligned cavities on either side of the central web defines integrally-formed compression spokes which connect the inner and outer hoop members. The annular reinforcing web is located on and affixed to either side of the central web portion and interconnects a mid portion of each spoke to a mid portion of the spokes on either side of it. Preferably, the annular reinforcing web is reinforced with fiber webbings on its outer side for added strength.Type: ApplicationFiled: March 18, 2011Publication date: September 20, 2012Applicant: CHEMTURA CORPORATIONInventors: Richard L. PALINKAS, Ian LASKOWITZ, Andrew TOPAR

Patent number: 8061398Abstract: A non-pneumatic tire comprising side cavities that are staggered with respect to laterally opposing side cavities, and laterally extending tread grooves that are either in substantial radial alignment with the cavities or substantially offset relative to the cavities. The tread grooves have at least one wall that is angled with respect to the radial direction, i.e., the direction relative to the tire's axis of rotation. The wall may be an open angle having an angle of 5° to 65° relative to the radial direction. Also provided are processes for making such tires and to off-the-road (OTR) vehicles employing such tires.Type: GrantFiled: October 24, 2008Date of Patent: November 22, 2011Assignee: Chemtura CorporationInventors: Richard L. Palinkas, Ian Laskowitz, George H. Nybakken

Patent number: 8056593Abstract: A non-pneumatic tire comprising side cavities that are staggered with respect to laterally opposing side cavities, and laterally extending tread grooves that are in substantial radial alignment with the cavities. In another embodiment, the invention is to a tire comprising side ribs that are staggered with respect to laterally opposing side ribs, and laterally extending tread grooves that are substantially offset relative to the side ribs. Also provided are processes for making such tires and to off-the-road (OTR) vehicles employing such tires.Type: GrantFiled: February 25, 2008Date of Patent: November 15, 2011Assignee: Chemtura CorporationInventors: Richard Palinkas, Ian Laskowitz, George Nybakken

Publication number: 20090110894Abstract: Polyurethane elastomer articles formed from prepolymer mixtures having free diphenylmethane diisocyanate (MDI) content from 2.0 to 5.0 wt %, based on the weight of the prepolymer mixture. The prepolymer mixtures comprise a polyester, polyether, or polycaprolactone (PCL) prepolymer and MDI. The polyurethane elastomer articles are formed by curing the prepolymer mixture with a chain extender, such as a curative comprising a methylenedianiline-sodium chloride complex. The articles have good physical properties that may weigh over 225 kg, and have a three-axis thickness greater than 10.2 cm.Type: ApplicationFiled: September 8, 2008Publication date: April 30, 2009Inventors: George H.
