A space truss type air-free tire

Abstract

A space truss type non-pneumatic tire structurally comprises a truss structure assembly, a rubber structure and a steel wire ring band; the rubber structure and the truss structure assembly are circumferentially distributed along the geometric center of a wheel hub; and the rubber structure, the steel wire ring band and the truss structure assembly form a composite elastomer. The truss structure assembly is composed of multiple sub modules, each sub module includes a plurality of rods, and a heptahedron is composed of the plurality of rods. The space truss type non-pneumatic tire simplifies the production process, can realize the separation of the truss structure and the rubber structure, under the premise of thorough solving of blowout of a pneumatic tire, is convenient for tire renovation and optimization, and helps to reduce rolling resistance; compared with the pneumatic tires in the prior art, the designed structure is maintenance-free and good in safety; compared with the tires lack of air in the prior art, the space truss type non-pneumatic tire is easy in replacement, light in weight and low in cost; and compared with non-pneumatic tire in the prior art, the space truss type non-pneumatic tire can solve the conflicts among noise, safety and comfortableness during high speed traveling, insufficient lifetime caused by a weak tire side structure, and other problems.

Description

technical field [0001] The invention relates to an air-free tire, in particular to a high-safety maintenance-free tire which is suitable for high-speed driving and is composed of a space truss structure, a steel wire ring belt and a rubber structure. Background technique [0002] The tire is the only part of the car that is in direct contact with the ground. Its function is to support the weight of the whole vehicle, and together with the suspension to buffer the unevenness excitation from the road surface, so as to ensure that the vehicle has good ride comfort and smooth driving; to ensure that the wheels and the road surface It has good adhesion to improve vehicle driving, braking and passability, and provide sufficient steering force for the vehicle. [0003] Tires can be divided into high-pressure tires (0.50-0.7MPa), low-pressure tires (0.2-0.5MPa), and ultra-low-pressure tires (below 0.2MPa) according to the air pressure in the tire. Low-pressure tires have good elast...
