Technical Field

The invention relates to the technical field of wheels, in particular to a safe wheel device.

Background

As vehicle reserves increase, various traffic accidents continue to increase, and the relevant data show that approximately 46% of every year highway traffic accidents are caused by tires, and 70% of these accidents are flat tires; the automobile tire burst is very dangerous when running at high speed, the rolling resistance of a tire burst wheel is increased rapidly, a lateral deviation moment pointing to one side of the tire burst is generated, the loss of the supporting force of the tire side leads to the vibration and the swing of the wheel, the supporting force of the lateral deviation is reduced, and finally the vehicle is out of control, at the moment, due to the influence of various factors such as the psychological panic of a driver and the like, correct treatment cannot be performed frequently, and the probability of occurrence of traffic accidents is increased.

The safe automobile wheel invented in the market at present mainly changes the anti-explosion performance of the tire or adopts the technology of the airless tire, but has many defects which are difficult to overcome, such as heavy weight, poor elasticity, large rolling resistance and high energy consumption of the uninflated tire body; the explosion-proof tire has poor comfort, large tire noise, difficult repair and high cost; the airless tire has large noise during driving, short service life, and no application on automobiles. And the outer tire structure is thickened to improve the anti-damage capability of the tire, the price is high, the driving experience is reduced, and therefore the tire is generally only used on vehicles with special requirements. Therefore, a new self-rescue tire structure for tire burst is needed to achieve the effects of light weight and wide application.

Disclosure of Invention

In order to solve the above problems, the present invention provides a safety wheel apparatus:

a safety wheel device comprises a main wheel and an auxiliary wheel which are concentric, wherein the auxiliary wheel is fixedly connected to one side of the main wheel, and the radius of the auxiliary wheel is smaller than or equal to that of the main wheel. When the main tire bursts and the tire diameter shrinks instantaneously, the auxiliary wheel can take over the supporting and running functions of the main wheel in an emergency manner, and accidents caused by out-of-control of the automobile are avoided.

Preferably, the main wheel comprises a main hub and a main tire which are connected with each other, the auxiliary wheel comprises an auxiliary hub and an auxiliary tire which are connected with each other, and the auxiliary hub is fixedly connected to one side of the main hub. The wheel hub stable in structure of wheel, through the interconnect installation of main wheel hub and auxiliary wheel hub to the stability of product has been improved.

Preferably, the auxiliary hub and the main hub are integrally formed. The integrated into one piece structure has better structural stability for detachable structure, and the security is high, but its cost is higher.

Preferably, the auxiliary hub is detachably matched with the main hub. Common threaded connection mode on the market can be adopted, original wheel hub on the car can be directly used to main wheel hub this moment, only need to be to the main wheel hub design installation of corresponding size vice wheel hub can.

Preferably, the auxiliary hub comprises a disk-shaped part and an edge part which are fixed with each other, the disk-shaped part and the main hub are connected through bolts or integrally formed, and the outer end of the edge part is fixedly connected with the auxiliary tire.

Preferably, the cross section of the edge part is of a horn structure or a T-shaped structure with a large outer part and a small inner part. The outer large part and the inner small part of the edge part just correspond to the edge part of the main tire, so that a better protection effect is achieved.

Preferably, the edge portion is an arc-shaped extension structure or a straight extension structure which is bent inward along the main tire. The curved arc-shaped extension structure is more attached to the structure of the main tire, so that the protection performance is better, the straight extension structure has better structural stability, and other accidents are not easy to happen.

Preferably, dish type portion one side is equipped with the protruding screens portion that a plurality of circumference distribute, main wheel hub is equipped with a plurality of screens grooves that correspond with protruding screens portion, screens groove and the cooperation of protruding screens portion.

Preferably, a tire pressure monitoring device is arranged in the main tire. Whether the tire is abnormal or not can be monitored in real time through the tire pressure monitoring device.

Has the advantages that: for common explosion-proof design mode on the market, this application with emergent auxiliary wheel direct mount in one side of main wheel, when main wheel takes place accidents such as flat tire, the diameter shrinkage after the main wheel flat tire, the diameter of auxiliary wheel is greater than the diameter of main wheel this moment, and auxiliary wheel will play the supporting role, avoids the car out of control, the simple and easy, the safe and reliable of structure of setting.
