Abstract
The utility model belongs to a non-inflated inner tube of a tyre. The utility model has the purposes that the utility model makes the inner tube have the function of non-inflation, simultaneously fills the space between a steel ring wheel and an outer tube fully and has the advantages of favorable effect of damping, lower cost and longer service life. Therefore, a cross-section of the inner tube is elliptic; the upper part of the inside of the inner tube is provided with a damping groove; the upper end of the damping groove is provided with an opening; a keel tube is arranged in the lower end of the inner tube. The utility model is used for the inner tubes of various vehicles, does not need to be inflated and is conveniently used.
Description
The utility model relates to a kind of inflation-free inner tyre.
Traditional inner tube of a tyre is used for damping, is mainly used between car steel-tired wheel and the cover tire forming between gas filed air zone, utilizes the compressibi1ity of air and damping.This traditional inner tube of a tyre that make with rubber and that have charging connector must possess crushing resistance, elasticity, retractility and leak tightness.Especially leak tightness is particularly important is the necessary condition that guarantees to form between steel-tired wheel and the cover tire pressurized air layer.But leak tightness then can not keep for a long time for the inner tube of a tyre, for example, the pressure variation of wheel in advancing causes sticking mouthful of gas leakage of rubber, or prick bad rubber inner tube because of knife-edge and leak gas and cause the vehicle can not cruising, must just can make vehicle ' by the parking tire patching, thereby incur loss through delay many things, and use cover tire also comparatively to bother, also must often inflate to guarantee that the inner tube of a tyre has enough pressure, more makes troubles to use, replace inflatable inner tube though there is the people to design at present with filled circles annular rubber, but damping effect is undesirable, but also can not the complete filling steel-tired wheel and cover tire between the space, cause both in conjunction with bad, can not cruising, and service life is short.
The purpose of this utility model provides a kind of inflation-free inner tyre, it is had exempt from gas filed function, also has the space between abundant filling steel-tired wheel and the cover tire simultaneously, has lower cost of good damping effect and tool and long service life.
Cross-sectional plane ovalize of the present utility model is established the damping groove on inner tube of a tyre top, and damping groove upper end is provided with opening, is provided with keel tube in the inner tube of a tyre of damping groove lower end.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that the non-inflatable good shock-absorbing function that just can have inflatable bladder, and the space between complete filling steel-tired wheel and the cover tire, cover tire can be fastened on the steel-tired wheel.And can guarantee that wheel has good damping pressure, and the friction force in operation and the brake process is also superior than traditional inner tube of a tyre, also has low, the easy to install advantage of cost simultaneously, and service life is also than long about 1 times of present inflation-free inner tyre.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model cross sectional representation
Fig. 2 is the utility model running condition cross sectional representation
The utility model is made up of vibration-absorptive material 4, and the cross-sectional plane ovalize of inflation-free inner tyre 1 is established damping groove 3 on inner tube of a tyre top, and damping groove upper end is provided with opening 2, is provided with keel tube 5 in the inner tube of a tyre of damping groove lower end.The inner tube of a tyre internal upper part that the damping grooved ring is formed around vibration-absorptive material.Keel tube is looped around the damping groove lower end in the inner tube of a tyre of being formed with vibration-absorptive material.Keel tube can be the keel tube that plastics or engineering plastics are made.Vibration-absorptive material is a rubber, or can be plastic cement, or can be elastomeric regeneratd rubber or regenerated plastic.
When the utility model is specifically made, regrown material by rubber or plastics or rubber and plastics is made the inner tube of a tyre, keel tube is preset in bottom in inner tube of a tyre mould, interior cross-sectional plane is oval, its top loop is around the damping groove, damping groove upper end open, keel tube are looped around in the inner tube of a tyre of damping groove lower end, and the inner tube of a tyre still is circular.
During use, the top of inflation-free inner tyre is positioned at the inner bottom part of car steel-tired wheel 6, and cover tire 8 still is traditional cover tire, and the cover tire pocket cover inner tube of a tyre is between the car steel-tired wheel, and cover tire pressure ring 9 still blocks and is pressed in the steel ring snap ring 7.Inner tube of a tyre pressurized makes the distortion of damping groove during use, and the opening misfit is in order to damping.Reaching the equal pressurized of keel tube vibration-absorptive material all around around the groove of damping simultaneously shrinks in order to damping.The effect of keel tube is to make the inner tube of a tyre have certain intensity, and guarantees good damping effect, and the inner tube of a tyre cross-sectional plane behind the pressurized is circular by elliptical deformation, and this moment, pressure resistance was strengthened, to guarantee to have good compressive resistance.Along with the rotation of wheel, the inner tube of a tyre is stressed and constantly changes, and pressurized inner tube of a tyre position does not restore to the original state, and also the pressure in dispersion pressure force forms good anti seismic efficiency.
The utility model can be widely used in the inner tube of a tyre of various wheels, is particularly suitable for vehicles such as bicycle, hand barrow, and it is low, easy to use to have a cost, the non-inflatable and good result of use of anti-seismic performance.
