Semi-packing type safety vehicle wheel

Abstract

The present inventioninvention discloses a half-wrapped safety vehicle wheel which belongs to the technical field of vehicle wheels. The present inventioninvention is to provide a novel vehicle wheel which has simple structure, is convenient in processing, and can meet requirements for safety, comfortability and passage. The technical proposal is that the vehicle wheel includes a wheel fellone, one or two air-filled working tires, solid safety tires; the air-filled working tires and solid safety tires are parallelly connected and assembled on the wheel fellone; the outer diameter of the working tires is more than that of the safety tires, wherein, one working tire wraps the tire crown of the safety tire from one side or two working tires wrap the tire crown of the safety tires from both sides to the middle, to form the visible working tire crown and safety tire crown hidden below the working tire crown. The present inventioninvention is applicable to transportation tools, such as vehicles, airplanes, etc.

Description

technical field [0001] The present invention relates to a wheel, more specifically, it relates to a semi-wrapped safety wheel. Background technique [0002] Pneumatic tires and solid tires have been widely used in vehicles and other mechanisms that need to roll on the ground with shock absorption. Pneumatic tires are small in mass and good in shock absorption, but weak in pressure bearing capacity and poor in impact resistance, and cannot guarantee safe control of the vehicle in case of air leakage or tire blowout. Some cars and sports cars that emphasize high-speed road handling use very flat tires. Although the safety guarantee in case of a flat tire is improved, the impact resistance of the wheels is further reduced at the same time, which affects the passing performance and riding comfort of the vehicle. The solid tire has strong pressure bearing capacity and good impact resistance, and does not produce the safety hazard of a pneumatic tire, but its mass is large and it...

Problems solved by technology

[0003] In order to change this situation, relevant engineers and technicians have carried out a large number of experimental studies, and proposed various technical solutions, such as Chinese patent ZL93104026.4 (disclosure date: January 15, 1994, publication number: CN1080240A) A disclosed "safety wheel with a spare wheel inside the tire", by setting an auxiliary wheel fixed to the rim in the working tire, it can reduce the sinking of the car body when the pneumatic tire leaks or blows out, and prevents the vehicle from getting out of control or roll over, and support the car body to continue driving for a certain mileage, but setting the spare wheel in the working wheel will cause difficulties in wheel processing, assembly and disassembly.

[0004] Another example is "a kind of safety tire for automobiles" disclosed by Chinese patent ZL01211548.7 (authorized announcement date: December 5th, 2001, announcement number: CN2463206Y). The sinking of the car body can prevent the car from rolling over, but the ring metal edge can only form a rigid support, which reduces the passing performance of the car and basically makes the car unable to drive normally.

[0005] Another example is the "safety wheel for a car" disclosed in Chinese patent ZL99253036.9 (announcement date: on October 25th, 2000, announcement number: CN2402511Y). By setting the auxiliary wheels directly on the outside of the working tires, the working tires are leaked. Reduce the sinking of the car body when the tire is flat or blown out, prevent the car from losing control or rollover, and support the car body to continue driving for a certain mileage; but setting the spare wheel on the outer side of the working tire may easily cause the car to scratch when driving or parking the edge of the road and an accident

[0006] Foreign research on safety wheels mainly focuses on the improvement of tire material and tire sidewall structure, such as a kind of " A low-cost run-flat tire with an improved carcass can continue to travel for a certain mileage when the tire has no air pressure by setting a reinforcing insert on the tire sidewall, but the tire processing technology of this structure is complicated, and this This technology is also mainly monopolized by a few large tire companies
