US Classification:

152324, 152 5, 152323

Abstract:

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.

International Classification:

C08G 18/10
B32B 27/40

US Classification:

428220, 528 59, 528 65, 528 64

Abstract:

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.

US Classification:

152323, 152 11, 152326

Abstract:

A tire rim for a non-pneumatic tire. The tire rim has an outer hoop that slideably engages a mounting ring disposed on the non-pneumatic tire. The mounting ring is slideably engaged in a lateral direction on the outer hoop. The rim and mounting ring can be secured using one or more mounting plates. The rim allows for the non-pneumatic tire to be easily mounted and removed.

US Classification:

152324, 152323, 1561101

Abstract:

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.

Assignee:

CHEMTURA CORPORATION - Middlebury CT

International Classification:

B60C 7/00

US Classification:

152246

Abstract:

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. The annular reinforcing web allows the tire to be made with less polyurethane material with no reduction in load carrying capability.
