Main and auxiliary double-wheel device of automobile

Abstract

The invention discloses a main and auxiliary double-wheel device of an automobile. The main and auxiliary double-wheel device comprises a wheel hub and a tire arranged on the periphery of the wheel hub, wherein a rigid auxiliary wheel is arranged in parallel outside the tire; the outer diameter of the rigid auxiliary wheel is greater than that of the wheel hub and is smaller than that of the tire; and the rigid auxiliary wheel is fixedly connected to the outer side of the wheel hub by a bolt. For the automobile using the main and auxiliary double-wheel device, an accident can be effectively prevented being happened when one tire is punctured in a running process; the automobile can be enabled to run to the road side or a repair shop at a low speed in a short distance when the tire leaks air in a parking process; the rigid auxiliary wheel is fixedly connected to the outer side of the wheel hub by the bolt, so that the wheel hub forms a cylindrical cavity structure, therefore, the strength and the supporting force of the wheel hub are enhanced; and compared with the prior art, under the same supporting force, the material thickness and the material weight of the wheel hub can be reduced.

Description

technical field [0001] The invention relates to an automobile wheel, in particular to an automobile main and auxiliary double wheel device. Background technique [0002] At present, the roads are getting better and better, the driving speed of cars is constantly increasing, and the penetration rate of cars is also greatly increasing, followed by more and more traffic accidents. Among them, the accidents caused by the sudden burst of tires during high-speed driving are the most tragic, and the driver cannot predict and prevent such accidents. This is mainly due to the structural defects of the current automobile wheels: the current automobile wheels It mainly includes the wheel hub and the tires arranged on the outer periphery of the wheel hub. There are two defects in this structure. One is that once the tire blows out, the wheel of the blown tire will sink, which will make the running direction of the car deviate, thus causing serious accidents; It is because the tires are...

Among them, the accidents caused by the sudden burst of tires during high-speed driving are the most tragic, and the driver cannot predict and prevent such accidents. This is mainly due to the structural defects of the current automobile wheels: the current automobile wheels It mainly includes the wheel hub and the tires arranged on the outer periphery of the wheel hub. There are two defects in this structure. One is that once the tire blows out, the wheel of the blown tire will sink, which will make the running direction of the car deviate, thus causing serious accidents; It is because the tires are flat and cannot move when the car is running at low speed or when it is parked. Many drivers will not change the tires, which is very inconvenient.
