Abstract
The utility model discloses a safety device for tyre deflation of a vehicle. The safety device comprises a ring-shaped anti-deflation body and also comprises a positioning piece, wherein the positioning piece is fixedly arranged on a rim; and a positioning groove is formed in the bottom surface of an inner ring of the anti-deflation body, and is correspondingly sheathed and connected on the positioning piece. The safety device disclosed by the utility model has the advantages that the problem of frictional heating generated by self rotation of the anti-deflation body when a tyre is burst or leaks air is solved, the use performance is stable and reliable, and the requirement of a medium-duty vehicle and the ministry of public security to the anti-bursting of the tyre of the vehicle can be met.
Description
Technical field
The utility model relates to self-propelled vehicle safety method field, relates in particular to the flat tire safety device of a kind of vehicle.
Background technology
If burst is blown out or the tire flat situation, tire then can break away from the normal position to vehicle under steam, thereby causes the outer ring surface of wheel rim or wheel rim outer shroud and tire top layer to contact with ground.If when occurring in high vehicle speeds, vehicle is lack of equilibrium, and especially wheel flutter is restive, thereby causes serious traffic accident.For tackling above-mentioned situation, prior art installs and fixes the flat tire safety device of vehicle at vehicle rim, burst is blown out or during the tire flat situation in vehicle travels, flat tire safety device then support tire is fixed on the wheel rim, to reduce the variable quantity of tyre break front and back wheel radius, thereby reduce the vehicle body deflection of the side of blowing out, make vehicle still have the control of good direction and turn to safely and handling such as brake, the place that thereby vehicle can be parked in a safety is changing of tire again, the danger and the accident that are caused with the back get out of hand of avoiding blowing out.
At present, although the flat tire safety device of the employed vehicle of prior art has supporting role, and do not locate between the wheel rim, can produce the rotation friction when stressed, make flat tire safety device and wheel rim generate heat easily.And the flat tire safety device of the vehicle overwhelming majority is to adopt nylon material to make at present, because the fusing point of nylon is low, poor toughness, be easy to wearing and tearing, therefore when rotating slippage and frictional heating between flat tire safety device and wheel rim, flat tire safety device and the tire inner wall, cause the flat device of tyre of nylon to damage distortion easily or rupture.Therefore, the flat tire safety device of prior art vehicle can only satisfy small-sized vehicle blow out or tire flat after a bit of distance of normally travelling, and can't satisfy higher as the requirement to the vehicle tyre anti-explosion safety of medium truck and the Ministry of Public Security.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of vehicle reliable and stable, that can guarantee the normal handling of vehicle flat tire safety device, to satisfy medium truck and the Ministry of Public Security to the requirement of vehicle tyre anti-explosion safety.
The purpose of this utility model is achieved by the following technical programs:
The flat tire safety device of a kind of vehicle that the utility model provides comprises ringwise anti-flat body; Comprise locations in addition; Described locations is fixed on the wheel rim; Its interior ring bottom surface of described anti-flat body is provided with positioning groove, and described positioning groove correspondence is socketed on the locations.The utility model makes by locations and keeps the location between anti-flat body and the wheel rim, avoided blowing out or during tire flat anti-flat body from then the frictional heating problem that produces.
Further, locations described in the utility model is more than two or two and is distributed on the wheel rim.
In the such scheme, for ease of making and installing, anti-flat body described in the utility model is connected to form with the end by two joints or the above anti-flat member of two joints.
Further, anti-flat member described in the utility model is provided with connecting bore at two ends, in order to by bolt adjacent anti-flat member is linked together; And the end face at two ends is respectively arranged with projection and groove, with the location and installation between the convenient adjacent anti-flat member.
In the such scheme, positioning groove described in the utility model is positioned at the two ends of anti-flat member, make two adjacent anti-flat members in the end common socket locations, thereby also further strengthened the adjacent connection steadiness of preventing between the flat member.
Anti-flat body described in the utility model is aluminium alloy castings, further to overcome the problem of anti-flat device distortion fracture.
The utlity model has following beneficial effect:
(1) realizes being located by connecting between the anti-flat body of the utility model and the wheel rim; both fit all the time; thoroughly solved blow out or during tire flat flat device of tyre because from then produce the problem of friction and then heating with wheel rim; not only protected expensive wheel hub; avoided the damage of flat device of tyre; and guaranteed the normal handling of vehicle, thereby play the effect of actv. safety control.
(2) the anti-flat body of the utility model adopts the aluminum alloy materials high-pressure casting to form, have that high strength, high tenacity, thermal diffusivity are good, characteristics such as corrosion stability and durability are good, can reach service life more than 10 years, and do not need to safeguard, solved the problem of the flat device of tyre easy deformation fracture of prior art nylon.Even the situation of blowing out in use occurred, also still can continue behind the changing of tire to use, the lifelong installation of each car once gets final product.
(3) simple in structure, the firm stable of the utility model, in-use performance has had significant raising, can guarantee that the medium truck below 10 tons still can normally travel more than 30 kilometers behind the rupture of tire, has satisfied the requirement of the Ministry of Public Security to the vehicle tyre anti-explosion safety.
