Disclosed herein is an airless are which absorbs shock and holds pressure applied to the tire through an auxetic spoke buffer without using air pressure. The airless tire includes a cylindrical tread being in contact with the ground, an axle fixing section having a smaller circumference than the tread and disposed inside the tread, and an auxetic spoke buffer connecting the tread and the axle fixing section and providing a buffering function. Accordingly, the airless tire is transformed only to an extent to properly function as a fire when the spoke buffer is transformed by pressure or impact and fully returns to an original shape when pressure or impact is removed.

The body is lightweight, made from shock absorbing materials and structures, and has pressure-airless tires, which enhances the safety of the passengers. The vehicle also includes an advanced hydrogen-electric or hydrogen-pneumatic hybrid propulsion system with quick refueling from existing infrastructure and various additional optional features and systems.

The present invention relates to an airless tire which supports load by an internal structure of the tire, comprising: an outboard tire; a plurality of spokes connected to the inside surface of the outboard tire; and a column foot for increasing the contact area of the spokes and the outboard tire. Therefore, localized bending deformation caused by the stress formed by the spokes can be prevented, uniformity of the airless tire can be improved, and the radial run-out performance is improved.

The present turbine fan rim, turbine fan airless tire and turbine fan hubcap designs are configured to remove air from under the underside of a moving vehicle when rotated in a particular direction, typically in a forward direction. This air movement can create a vacuum below the vehicle, which can create a down force on the vehicle increasing traction between the vehicle's tires and the road surface and lowering the vehicle's center of gravity. This downward force and partial vacuum can thus increase as the rotational velocity of the tires increases, providing greater traction at higher speeds. An additional benefit to these wheel, airless tire, and hubcap designs is the cooling effect that would be created by the flowing air on brake parts that are located near wheels of nearly all vehicles.

The invention discloses an airless tire. The airless tire comprises a rubber tire tread (1) and a spoke (2). The spoke (2) comprises a spoke outer rim (21), a spoke middle rim (22), a spoke inner rim (23), outer spoke wires (24) and inner spoke wires (25). The rubber tire tread (1) is installed on the spoke outer rim (21) in a sleeving mode. The spoke outer rim (21) is fixedly connected with the spoke middle rim (22) through the outer spoke wires (24). The spoke middle rim (22) is fixedly connected with the spoke inner rim (23) through the inner spoke wires (25). The positions between the spoke outer rim (21) and the outer spoke wires (24) are paved with water accumulating preventing layers (3). According to the airless tire, the situation that a tire blows out when a automobile runs at a high speed can be prevented, and the safety and reliability of automobile running are improved; the radial elastic property and the buffer capacity of the airless tire and the smoothness during automobile running are improved; the airless tire capacity of resisting the hub driving torque during starting and the tire tread friction moment during braking is improved; and meanwhile the water accumulating preventing function is achieved.

An airless tire has a tread ring having a footprint, a hub positioned on a radially inner side of the tread ring and formed to be fixed to an axle, and a spoke connecting the tread ring and the hub and having a tread connection portion connected to an inner-circumferential surface of the ring and a hub connection portion connected to an outer-circumferential surface of the hub. The ring and the tread connection portion of the spoke satisfy 0≦E1≦0.5, 0<E2≦1.0 and 0≦E3<0.3, where E1, E2 and E3 represent ratios of first, second and third regions on the inner-circumferential surface of the ring and the first, second and third regions are divided based on a tire axial component length of the tread connection portion measured at a point in a circumferential direction of the ring.

Radial elastic performance and buffer ability of the airless tire are improved, smoothness during traveling of the automobile is improved, and the resistance to driving torque of a wheel hub during starting and resistance to friction moment of the tread during braking of the airless tire are improved.

An airless tire includes a cylindrical tread ring having a ground contact surface, a hub disposed radially inward of the tread ring and a plurality of spokes each connecting the tread ring to the hub. The hub includes a disk portion to be fixed to an axle and a cylindrical portion extending in an axial direction of the tire from a radially outer portion of the disk portion. The cylindrical portion includes a radially inner surface being provided with a circumferentially extending projection protruding radially inwardly.

An airless tire comprises: a tread ring having a tread, a hub located radially inside the tread ring, and cross radial members connecting the tread ring with the hub. The cross radial members include first radial members and second radial members crossing the first radial members.
