Abstract:
A buoyant vehicle tire device for facilitating driving in muddy soil includes a tire having an exterior wall and a pair of side walls is attached to each one of a pair of side edges of the exterior wall. A vehicle rim is sealed against the end edge of each side wall and encloses a pressurized space between the side walls and the exterior wall of the tire and the vehicle rim. A valve is coupled to the vehicle rim and is in fluid communication with the pressurized space. A plurality of depressions is positioned on the exterior wall and is pushed out from a first position to a second position when the pressurized space receives additional air. The first position of each of the depressions has a container space receiving air when driving in muddy soil, wherein the depressions provide buoyancy to the tire in muddy soil.
Abstract:
A landing gear tire traction control system and methods are presented. An outer tire of an aircraft wheel is depressurized to a depressurized state in response to a non-optimal aircraft landing condition. An inner rotor of the aircraft wheel contacts the outer tire in response to the depressurized state, and a plurality of traction studs are deployed to protrude from the outer tire in response to the inner rotor contacting the outer tire.
Abstract:
A pneumatic tire for a multiple-tracked vehicle is asymmetrical and has a convex tread section that is curved radially inward and extends to a tire sidewall.
Abstract:
Adjustable studded tire system for operation while driving or parking. The system includes a hydraulic pump unit which by elastic tubes molded into the outer layer of the vehicle tire can move studs into and out of the vehicle tire without having any part of the stud system penetrate the tire casing.
Abstract:
A tire, particularly for operation in icy conditions which has studs that are mounted so they can be retracted or extended pneumatically without changing the external configuration or shape of the tire, and can be extended without utilizing any external pressure sources.
Abstract:
A tire with retractable hollow studs and pressure sensing means for extending the studs when the pressure in the tire exceeds a selected pressure and for retracting the studs at a second and lower pressure.
Abstract:
The invention concerns a dual-purpose tire which can be used on both dry and snow-covered or icy roads, being made up of a monobloc casing comprising, in addition to its main tube, a second, smaller tube having a tread with points, these two tubes being inflated separately, so that the tread with points can by selection by brought level with or set back from the tread of the main tube.
