The disclosed technology generally relates to a tire and more particularly to a non-pneumatic tire. The non-pneumatic tire that has maneuverability similar to a pneumatic tire even without using air pressure, and can support the load of a vehicle and can guide performance-oriented tire deformation behavior by using a meta structure. In an aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that serves as a structural support between the rim and the tread, in which the spoke unit is formed in a meta structure in which unit structures are repeated.

Non-pneumatic tire

The disclosed technology generally relates to a tire, and more particularly to a non-pneumatic tire that has handling performance similar to a pneumatic tire, supports the load of a vehicle and improves riding comfort by employing a parametric structure. In one aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that functions as a structural support between the rim and the tread, in which the spoke unit is formed by circularly arranging spokes. The spokes have a single closed-loop longitudinal cross-section circumscribed to the rim and around the center of the tire.

The present invention relates to an airless tire, and includes first and second bands that face each other with a distance interposed therebetween, a plurality of spokes that connect the first band to the second band and are provided at intervals, and first and second connecting members that connect the adjacent spokes. The spoke includes a first member of which one end is curved from the first band toward the second band, and a second member of which one end is curved from the second band toward the first band. The other ends of the first and second members are connected to each other, and the first and second members are curved in opposite directions.

Airless tire

Disclosed herein is a non-pneumatic tire with a reinforcing member. The non-pneumatic tire includes a tread part which comes into contact with the ground, a rim part which is coupled to an axle, an outer annular band part which forms an interface with an inner surface of the tread part, an inner annular band part which forms an interface with the rim part, a spoke part which is disposed between the outer annular band part and the inner annular band part and functions as a support, a connector which connects spokes of the spoke part to each other, and a reinforcing member which has a plate wire structure. The non-pneumatic tire can effectively and sufficiently withstand the weight of a vehicle. Further, the performance of the tire is balanced with respect to the contact area, the displacement extent and the resistance to rolling.

Non-pneumatic tire with reinforcing member having plate wire structure

A non-pneumatic tire for a vehicle is disclosed. The non-pneumatic tire includes a tread, a rim part, inside and outside annular bands, a spoke member, and a pair of protective films. The tread comes into contact with a road surface. The rim part is connected to the axle of a vehicle. The inside and outside annular bands are disposed between the tread and the rim part, and are coaxially spaced apart from each other. The spoke member includes supports disposed in a predetermined pattern and configured to connect the inside and outside annular bands, and openings defined by the supports. The pair of protective films are disposed at both ends of the tire in the widthwise direction of the tire, and prevents foreign substances from infiltrating into the openings of the spoke member. The protective films are made of the same material as the spoke member and integrated with the spoke member.

Non-pneumatic tire for vehicle

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.
