Abstract

The utility model provides a safety supporting wheel preventing tyre burst, and aims at solving the problems that the larger fall between the outer margin of a wheelboss and the ground after tyre burst leads to the side tipping of a vehicle running at a high speed, thereby causing unwanted casualty and losses of property, etc. The safety supporting wheel has the technical proposal that the wheelboss of the wheel is provided with a dished disc the diameter of which is larger than the maximum outer margin diameter of the wheel. The dished disc and the wheelboss can be in an integrated structure or a combined structure. The outer margin of the dished disc is provided with a ring-shaped soft rubber. Compared with the prior art, the supporting function of the dished disc ensures that a vehicle does not roll over immediately once the vehicle running at a high speed has a tyre burst accident, and the driver has enough time to take a braking measure; when the pressure of the tire is low, the driver is reminded to charge the tires in time. Besides, the driver is also reminded about overloading of the vehicle, thereby taking measures to reduce the load. In this way, the safety of vehicles in traveling is ensured.

Description

Security support wheels for preventing tire burst

Affiliated technical field

The utility model relates to a kind of automobile component, is a kind of Security support wheels for preventing tire burst specifically.

Background technology

The present wheel of Chinese and foreign car does not use the technology of runflat safety supports.Existing runflat technology is just installed the radio pressure sensor in motor tire, testing automobile tire pressure situation of change is in case automobile flat tire.But automobile in particularly running at high speed, if wheel is blown out suddenly, also can't prevent also simple and practical without comparison safety measure in actual use now.Motor tire is in long-term use, particularly automobile is when running at high speed, because a variety of causes, tire might the moment explosion or is not had air pressure, because of automotive hub outward flange and ground drop bigger, people have little time to take safety precaution in a short period of time, and the easiest generation vehicle side turning accident causes casualties and property damage.

Summary of the invention

It is a kind of for after solving wheel and blowing out that goal of the invention of the present utility model is to provide; because of wheel hub outward flange and ground drop turn on one's side the vehicle of running at high speed greatly easily; cause the unnecessary personal casualty and the difficult problem of property damage, can effectively protect the Security support wheels for preventing tire burst of the traffic safety of vehicle.

The technical solution of the utility model is: the wheel hub groove position intermediate at wheel is provided with dished disk, and the diameter of dished disk is greater than the maximum outward flange diameter of wheel hub, with after solving wheel and blowing out, and wheel hub outward flange and the bigger problem of ground drop.

Dished disk of the present utility model and wheel hub can be integrated.

When dished disk of the present utility model and wheel hub were integrated, the dished disk outward flange had the small gap of two symmetries, and the small gap degree of depth is that the dished disk outward flange is to the outer peripheral straight-line distance of wheel hub.To make things convenient for the loading and unloading of motor tire.

Dished disk of the present utility model and wheel hub can be sectional construction, and dished disk is that two semi-disc assemblings are synthetic.

Feature of the present utility model also is: the dished disk outward flange is equipped with the annular arrangement soft rubber.

Should manufacture the dished disk of corresponding size for different wheels, to satisfy operating needs.

The utility model compared with prior art, has following advantage: one, because of the supporting role of dished disk, in case the accident of blowing out, vehicle can not turned on one's side immediately in the high vehicle speeds, and chaufeur can have time enough to take the vehicle safety brake measure; When two, tire pressure is on the low side, can remind chaufeur in time to replenish air pressure to tire; Three, can remind the chaufeur overload of vehicle, be necessary to reduce load.Can effectively protect the traffic safety of vehicle.

Description of drawings

The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.

Fig. 1 is an assembling scheme drawing of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Among Fig. 1, Fig. 2, be provided with dished disk 2 in the wheel hub 1 groove position intermediate of wheel, the diameter of dished disk 2 is greater than wheel hub 1 maximum outward flange diameter.Dished disk 2 is a sectional construction with wheel hub 1, and dished disk 2 is that two semi-disc assemblings are synthetic, and there is bolt of rear end plate two semi-disc junctions, are used for two semi-discs are attached at supporting wheel hub 1.Adorn an annular arrangement soft rubber 3 at dished disk 2 outward flanges, annular arrangement soft rubber 3 can play the pressure buffer effect.Under the normal situation of tire pressure, annular arrangement soft rubber 3 is (20 to 30 millimeters in its gaps) of discord tire inner surface contact, only when air pressure of automobile tire is low, just contacts with tire inner surface, plays a supportive role.If automobile flat tire, dished disk 2 and annular arrangement soft rubber 3 can in time be played a supporting role, and at this moment automobile can also the safety traffic certain distance, and chaufeur can feel that motor tire breaks down, and can have time enough to take the vehicle safety brake measure.

Dished disk 2 material therefors that use in the wheel hub 1 of wheel can be identical with wheel hub 1.Annular arrangement soft rubber 3 materials can be identical with rubber for tire, and annular arrangement soft rubber 3 is to install with the method for expanding with heat and contract with cold when installing on dished disk 2.
