Provided is a non-pneumatic tire in which buckling can be prevented without a weight increase, the non-pneumatic tire including a spoke structure. The spoke structure is obtained by circumferentially arranging spokes intermittently at intervals and coupling together annular cylindrical outer member and cylindrical inner. The spoke structure is joined to an inner peripheral side of a tread ring. At least some of a plurality of spaces formed between two spokes adjacent to each other in the tire circumferential direction have an air-containing structure.

Non-pneumatic tire

A material adapted to regulate vibration by distributing and partially dissipating vibration exerted thereon.

Vibration dampening material and method of making same

A tire noise reducing system comprises a wheel rim, a pneumatic tire to be mounted on the wheel rim and a noise damper to be disposed in an annular tire cavity enclosed by the wheel rim and the pneumatic tire mounted thereon, wherein the noise damper is made of a multi-cellular material whose volume S2 is in a range of not less than 0.4% of the volume S1 of said annular tire cavity. Preferably, the specific gravity of the damper is set in a range of from 0.005 to 0.06.

Tire noise reducing system

Provided is a low noise pneumatic tire in which the noise absorbing member on the inner peripheral surface of the tire is made less likely to be damaged when the pneumatic tire is removed from the rim. The pneumatic tire includes a noise absorbing member of a porous material which is attached to an inner peripheral surface of the tire. In the pneumatic tire, a lubricant is applied to the inner peripheral surface of the noise absorbing member. Alternatively, both end portions, in a tire width direction, of the inner peripheral surface of the noise absorbing member are covered with protective layers harder than the noise absorbing member.

Low noise pneumatic tire

An assembly of a pneumatic tire and a rim and a sound suppressing body used for the assembly, the assembly wherein the sound suppressing body (5) having a volume (V2) of 0.4 to 20% of the total volume (V1) of a tire inside hollow (4) and formed of a sponge material extending in circumferential direction is installed in the tire inside hollow (4) formed by the tire (2) and the rim (3); the sound suppressing body (5) comprising a tire side sound suppressing body (10) having a bottom face (10B) fixed to the tire (2) or a rim side sound suppressing body (11) having a bottom face (11B) fixed to the rim (3), wherein the area gravity (G) of the tire side sound suppressing body (10) or the area gravity center (G) of a sound suppressing body main part (16) exceeding the bead base line (BL) of the rim side sound suppressing body (11) is positioned in an area (Q) ranging from the middle point (T/2) of a height (T) from a reference plane (N) to the tip of the sound suppressing body to the reference plane (N).

Assembly of pneumatic tire and rim, sound suppressing body used for the assembly, and pneumatic tire storage method

In a tire-wheel assembly, in which a pneumatic tire is installed to a rim of a wheel, an auxiliary ring or auxiliary plate of which dynamic balance has been adjusted is attached coaxially with the wheel onto a rim flange on an outside of the wheel when the tire-wheel assembly is attached onto a vehicle.

Tire-wheel Assembly

A shock absorber for an automobile which exhibits a vibration damping effect in a wide range of a frequency, while suppressing generation of frictional noise. The shock absorber for the automobile has a buffer member interposed between parts. The buffer member has a laminated structure including a plurality of vibration damping layers each having a peak of loss tangent tanδ in a range of a frequency which is different from others and surface layers made of thermoplastic resin.

Shock absorber for automobile

A shock absorber for car such as a bush used for a suspension capable of simultaneously meeting the requirements for a plurality of characteristics such as a steering stability and a riding comfortableness, comprising buffers installed between parts, wherein the elastic moduli of the buffers are differentiated from each other according to the directions thereof.

Shock absorber for car

Ein Stosdampfer fur ein Kraftfahrzeug weist einen Vibrationsdampfungseffekt in einem breiten Frequenzbereich auf, wahrend die Erzeugung von Reibgerauschen verhindert wird. Der Stosdampfer fur das Kraftfahrzeug weist ein Pufferelement auf, das zwischen Teilen angeordnet ist. Das Pufferelement weist eine geschichtete Struktur mit mehreren Vibrationsdampfungsschichten mit einem jeweiligen Spitzenwert des Verlusttangens tandelta in einem Frequenzbereich, der unterschiedlich ist von anderen, sowie Oberflachenschichten aus thermoplastischem Harz auf.

Stoßdämpfer für ein Kraftfahrzeug

Provided is a method of fitting a tire-and-wheel assembled body to an axle, which is capable of resolving imbalance in a state of fitting an assembled body including a tire and a wheel to an axle. In this fitting method, a tire is fitted to a wheel, and then core positions of fastening holes are, or a core position of a hub hole is, adjusted in the wheel to minimize an amount of eccentricity of an assembled body including the tire and the wheel.
