Abstract:
A pneumatic spacer and cushioning tire assembly is provided with a carcass component and a tread section component. A plurality of anchor plates are molded into the tire carcass in the crown section thereof. The anchor plates are further retained in position on the tire carcass by an elastomer insulated inextensible filament reinforced ply composed of a plurality of inextensible filaments which comprise a portion of the tread section component.The anchor plates are equipped with fastener receiving means which are provided to allow the fastening of traction plates to the anchor plates. Traction plates, once attached firmly to the anchor plates, protect the tire from damage as well as providing increased traction.The complete tire assembly provides an armored resilient ground engaging unit for use on construction equipment.
Abstract:
Track belts designed to fit circumferentially around a pneumatic bladder or tire carcass can be sealed against the ingress of soil and rock between the track shoes attached about the outer periphery of the belt by forming individual and permanent flat sites on the outer circular periphery of the belt so the flat undersurface of each track shoe is nested on a flat shoe site and therefore does not have triangular shaped gaps under its leading and trailing edges. A transverse rib of elastomer, raised from the surface belt between each of the adjacent flat sites further seals the belt in the narrow gaps formed between adjacent track shoes thereby preventing the ingress of soil and rock in these gaps when the shoes pass through a footprint formed as the pneumatic supported system is rolled. In elevation the outer surface of this pneumatic carcass supported belt is polygonol in appearance with a ridge or rib located at each joint between adjacent flat surfaces of the shoe sites which are circumferentially disposed around the belt.
Abstract:
A snow tire having radially spaced steel gripping teeth means which are exposed to contact with the icy surface when said tire is partially deflated and are recessed within the tire tread by fully inflating the tire. The tire is provided with a plurality of U-shaped steel loops which are radially spaced around the tire. The base of the loops are provided with a plurality of teeth members around the outer surface thereof, said base with teeth members being disposed within slots or recesses provided across the tread portion of the tire. By partially deflating the tire, the tread portion is retracted thereby allowing the teeth portion of the steel loops to contact the road or snow surface providing increased traction on said icy surfaces.
