A pneumatic tire including: a tire body including a tire side portion whose outer surface is composed of side-covering rubber; a communication device embedded in the tire side portion of the tire body. When a region in which the communication device is located in the tire radial direction and the tire circumferential direction of the tire side portion is defined as a device region, the outer surface of the tire side portion protrudes in the device region, and thickness of the side-covering rubber is thinner in the device region than around the device region.

A heavy-load combined tire comprises a hollow rubber base tire assembled with a rim, a replaceable rubber wear ring combined on the outer circumference of the base tire, high-elasticity solid particles filled in an inner cavity of the base tire, and inflation opening leather which is arranged between an opening of the inner cavity of the base tire and the rim and is provided with an inflation cavity, the outer circumferential surface of the base tire and the inner circumferential surface of the wear ring are provided with mutually embedded convex and concave parts, and two sides of the circumference of the wear ring are provided with flanges which are attached to the side surface of the base tire and radially stabilize the wear ring on the base tire. The tire has the positive effects that the replaceable wear ring is assembled on the base tire, the base tire can be used for a long time, the required tire pressure is obtained through the high-elasticity rubber ball and the inflation inlet leather, the bearing capacity is greatly improved, the size is reduced compared with an existing heavy-duty tire, the inflation part is far away from the ground, and the inflation effect is good. And potential safety hazards caused by pressure reduction or tire burst of the tire due to puncture are eliminated. The high-difficulty technology and the large amount of material consumption for manufacturing heavy-duty tires are avoided, and the manufacturing cost and the use cost are greatly reduced.

To provide a pneumatic tire which can improve durability of a protrusion to indicate a position of a communication device.SOLUTION: A pneumatic tire according to the present invention comprises: a tire body with a tire side part where an external surface is constituted by a side coating rubber; and a communication device which is buried in the tire side part of the tire body. When a region of the tire side part where the communication device is positioned in a tire radial direction and in a tire circumferential direction is regarded as a device region, the external surface of the tire side part is protruded at the device region, and the thickness of the side coating rubber is thinner at the device region than the periphery of the device region.SELECTED DRAWING: Figure 8

The utility model relates to the field of cart outer tires, and discloses a cart outer tire convenient to replace, which comprises a hub, a side plate is movably connected to one side of the hub, a positioning rod is fixedly connected to one side of the hub, a nut is movably connected to the outer wall of the positioning rod, an inner tire is movably connected to the outer wall of the hub, and the inner tire is fixedly connected to the hub. The outer wall of the inner tire is movably connected with an outer tire body, and the outer wall of the outer tire body is movably connected with an anti-skid rubber strip. According to the cart outer tire convenient to replace, through the arrangement of the outer tire body, the splice plates, the fixing rods and the anti-falling caps, the cart outer tire can have the effect of being convenient to replace, when the cart outer tire needs to be disassembled, assembled and replaced, a positioning reinforcing structure can be disassembled through simple rotating disassembly, and the cart outer tire is convenient to replace. Therefore, splicing and reinforcing of the outer tire of the cart are relieved, people can disassemble and replace the outer tire of the cart on the premise of not using a disassembling tool, the convenience of maintenance and use is improved, and the use requirements of people are met.

The utility model relates to the technical field of vehicle tires, in particular to a double-filling type wheel assembly which achieves structural compounding, light weight and high weather resistance through an air and polyurethane double-filling technology. The tire is provided with an outer tire and an inner bearing tire, the inner bearing tire is located in the outer tire and fixedly connected with the inner wall of the outer tire in a seamless mode, the inner bearing tire and the outer tire form a compressed air cavity, an adhesive layer is arranged on the side, facing the rim, of the inner bearing tire, the adhesive layer, the inner wall of the outer tire and the rim jointly form a polyurethane foaming cavity, and a compressed air inlet pipe assembly is arranged on the inner bearing tire. An air outlet of the compressed air inlet pipe assembly leads to the compressed air cavity, the polyurethane filling opening leads to the polyurethane foaming cavity, and an air outlet of the inflating valve faces an air inlet of the compressed air inlet pipe assembly. The double-filling type wheel assembly integrates the advantages of a pneumatic tire and a polyurethane tire, is high in wide-temperature adaptability and stable in elastic modulus, avoids the risk of tire burst, and has high application value in medium and low speed vehicles.

The utility model discloses a light-weight motorcycle inner tube structure, and relates to the technical field of motorcycle inner tubes. Comprising a main inner tube body, an auxiliary inner tube body is arranged in the main inner tube body, the size of the auxiliary inner tube body is smaller than that of the main inner tube body, and the main inner tube body and the auxiliary inner tube body are used in cooperation with silicone oil, so that when a motorcycle runs, the main inner tube body and the auxiliary inner tube body deform and vibrate to a certain extent; the silicone oil can bring heat from a higher-temperature area to a lower-temperature area to accelerate heat transfer and dissipation, so that the service lives of the main inner tube and the auxiliary inner tube are prolonged, and meanwhile, the silicone oil has extremely low surface tension and friction coefficient, so that the service life of the main inner tube and the auxiliary inner tube is prolonged. When silicone oil is fully filled between the main inner tube and the auxiliary inner tube, a uniform oil film can be formed between the two layers of inner tubes, so that friction is effectively reduced, heat and abrasion of the inner tubes caused by friction are reduced, and the service life of the inner tubes is further prolonged.
