Drawings
FIG. 1 is a schematic view of a novel fuel-efficient inflation-free tire and rim according to the present invention.
Description of the embodiments
The invention is further described below with reference to the drawings and examples.
The overall design and manufacture of the tire is performed according to the specifications of the tire 100, the load level, the speed level, the ground contact surface size, the tread rubber/belt/base rubber/gum deformation, and other technical parameters.
The size, pressure, density and manufacturing method of the base glue 103 material and the air chamber 105 are determined by the design dimensions and the elastic modulus. In the method 1, a proper amount of proper foaming agent (determined by gasification temperature, gas generation amount and the like) is added into a material with good gas tightness (such as butyl rubber and the like), and the mixture is uniformly mixed, heated and foamed with micro closed pores. And 2, injecting a proper amount of proper foaming agent (determined by gasification temperature, gas generation amount and the like) into the unvulcanized molding colloid after mixing the materials with good gas tightness (such as butyl rubber and the like) to form one or more layers of gas chamber lattices, and heating to foam closed cells. In the method 3, proper prefabricated independent air chambers (such as air chambers made of materials such as butyl rubber) are uniformly embedded into common unvulcanized or presulfided colloid which is prepared by mixing base rubber materials (such as fiber rubber and the like), so that one or more layers of air chamber lattices are formed and vulcanized into a whole. Appropriate foaming agents (determined by gasification temperature, gas generation amount and the like) and liquid substances can be added into the air chamber according to requirements to adjust the pressure and performance of the air chamber.
The base rubber 103 can be subjected to common-mode heating vulcanization after being laminated and molded with the tread rubber 101, the belt layer 102 and the toe-mouth rubber 104 in a conventional production mode; or can be manufactured by mould pressing and vulcanization alone and then be vulcanized and synthesized with other parts of the tire. The method 1 is manufactured by single mould pressing vulcanization, and can adopt a physical foaming method of gas (such as macromolecular gas like nitrogen).
Different from the fact that the tread supporting force of the pneumatic tire is basically the same in the vehicle, the tire of the invention is compressed along with the volume of the deformation air chamber 105, the pressure intensity is increased, the supporting force is increased, the normal pressure intensity of the air chamber 105 can be smaller than the tire pressure of the pneumatic tire with corresponding specification, and therefore the supporting force at the front end of the footprint is smaller than the middle end of the footprint in the running direction of the tire, and better rolling property is obtained, and more oil is saved.
Because the normal pressure of the tire air chamber is smaller than the tire pressure characteristic of the pneumatic tire with corresponding specification, the radial tension born by the tire air chamber is smaller, the usage amount of the belt layer can be properly reduced, and the cost is saved.
The combination surface of the tire 100 and the rim 200 is cylindrical with the same inner diameter, and the combination surface of the rim 200 and the tire 100 is cylindrical with the same outer diameter, so that the assembly and disassembly are convenient.
The combination surface of the tire 100 and the rim 200 is in a circular arc shape in the cross section of the tire 100, and the combination surface of the rim 200 and the tire 100 is in a concave shape, so that the axial displacement of the tire is avoided.
The tire 100 and rim 200 have radial holes 106 and the rim 200 and tire 100 have mating raised members 201 (removable) for securing the tire and dissipating heat.
The tyre 100 and rim 200 have several axial grooves 107, and the rim 200 and tyre 100 have suitable protrusions 202 for enhancing the contact surface between the tyre and rim, positioning, heat dissipation and circumferential torsion.
The back of the joint surface of the rim 200 and the tyre 100 is provided with a plurality of vane-shaped bulges 203 which are manufactured in a forging, welding, milling and other modes, so that the rim support strength, the heat dissipation area and the fan cooling are increased.
The 2 side edges of the rim are provided with circumferential bulges 204, and at least one part containing the circumferential bulges 204 on one side edge can be separated from the rim body, and the part is connected with the rim body through screws or bolts, so that the tire is convenient to disassemble and assemble, and the axial displacement of the tire is avoided.
The rim is made of aluminum alloy or steel, the offset distance of the rim ranges from-10 mm to 300mm, and the large-area joint surface of the rim 200 and the tire 100 not only ensures the supporting strength and balance, but also is beneficial to heat dissipation.
With the above-described preferred embodiments according to the present invention as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present invention. The technical scope of the present invention is not limited to the description, but must be determined according to the scope of the claims.
