Description

Motor tire deficency and wheel warning device for looseness thereof

The utility model relates to a kind of motor tire deficency and wheel-looseness alarm device thereof, a kind of tire deflation and loosening annunciator of wheel that monitors used automobile in operator's compartment of more specifically saying so.

Automobile is in the process of travelling, and tire pressure whether normal is one of essential condition that guarantees vehicle safe driving.The often very difficult discovery of gas leakage takes place in automobile now tire in motion, and this not only can make the automoblie tyre breakage, but also great train operation accident can take place, and causes unnecessary economic loss; In addition, owing to damaging, the bearing on the automotive wheel, axle cap make loosening this of wheel also can cause the generation of contingency.For solving the problem of this respect, also the someone has made design, but its structure more complicated, pneumatic shuttle all is arranged on outside the tire tube valve, pneumatic shuttle outside tire tube valve can be because in the galloping process, the influence of external environment condition such as high and low temperature and muddy water and very easily damaging, the accuracy that influence is reported to the police, service life is lower.

At the problems referred to above, the purpose of this utility model provides the warning device of a kind of simple in structure, safe and reliable, the bearing that can inform driver's motor tire deficency and wheel exactly, the loosening operating mode of axle cap.

The purpose of this utility model can reach by following measure: this motor tire deficency and wheel warning device for looseness thereof, mainly by the buzzing indicating device, baroswitch, conducting ring, composition such as carbon brush component and contactless switch, the buzzing indicating device places in the operator's compartment, the principal feature of its structure is that described buzzing indicating device is by lead and carbon brush component, conducting ring joins, carbon brush component and the contactless switch that is installed on the carbon-brush holder are fixed on the brake disc, conducting ring is installed on the wheel hub, and link to each other with baroswitch with lead, the baroswitch housing that is fixed on the valve inside bottom is in valve inside is installed in valve tube, baroswitch is by housing, cylinder, piston rod, the air pressure adjustment screw-casing, spring and leather cup are formed, housing is down " cross bar " shape, there are two notches the upper end, piston rod is slided up and down, one cylinder is arranged in the housing, a leather cup is fixed in the lower end of cylinder, leather cup is sitting in down the right-angled crossing place of " cross bar " shape housing, be with spring and air pressure adjustable screw cover on the cylinder, the upper surface of air pressure adjustment screw-casing is oblique downwards and has the age of a draught animal, and the piston rod that interts in cylinder and housing notch was stuck on the age of a draught animal.

The principle of work of the utility model motor tire deficency and wheel warning device for looseness thereof is as follows: open automobile ignition switch, automobile line is connected, the tire internal gas pressure just often enters gas in the housing by the notch on the housing, and cylinder is separated with the valve inside thimble; In case motor tire deficency, tire internal gas pressure descend, when pressure during less than the elastic force of baroswitch upper spring, spring drives on the cylinder and moves, and cylinder is contacted with the valve inside thimble, and constitute the loop with conducting ring and carbon brush component, begins warning; When the bearing of automotive wheel, when axle cap is loosening, automotive wheel is loosening, its in the process of travelling be installed in carbon-brush holder on contactless switch contact with conducting ring, conducting ring makes the buzzing indicating device that is connected get the electric signal that gives the alarm by the contactless switch on the carbon-brush holder, and demonstrates concrete location of fault on the read-out of buzzing indicating device.

The utility model motor tire deficency and wheel warning device for looseness thereof are owing to be that baroswitch is set in tire tube valve; make the tire of automobile; even at height; use in the environment of low temperature and muddy water and also can obtain the actv. protection; in case it is loosening tire flat and wheel to occur; can be in time; give the alarm exactly; the driver can in time be discovered and take appropriate measures; prevented effectively motor tire because of gas leakage can not in time find to damage again; prolonged the service life of motor tire; also avoided the generation of train operation accident; reached the purpose of traffic safety and protection tire, this annunciator is simple in structure; reliable working performance; long service life.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the constructional drawing that the utility model motor tire deficency and the used baroswitch of wheel warning device for looseness thereof and valve inside link together;

Fig. 2 is the scheme drawing of the utility model motor tire deficency and wheel warning device for looseness embodiment thereof.

Referring to Fig. 1, used baroswitch (10) is by housing (6) on this motor tire deficency and the wheel warning device for looseness thereof, cylinder (1), piston rod (2), air pressure adjustment screw-casing (3), spring (4) and leather cup (5) are formed, housing (6) is down " cross bar " shape, there are two notches the upper end, piston rod (2) is slided up and down, the lower end of the cylinder (1) in the housing (6) is fixed with a leather cup (5), leather cup (5) is sitting in down the right-angled crossing place of " cross bar " shape housing, be with spring (4) and air pressure adjustable screw cover (3) on the cylinder (1), the upper surface of air pressure adjustment screw-casing (3) is oblique downwards and has the age of a draught animal, and the piston rod (2) that interts in cylinder (1) and housing (6) notch was stuck on the age of a draught animal.Air pressure adjustment screw-casing (3) can be controlled starting to control a little of baroswitch (10) according to the requirement of motor tire internal gas pressure.

By Fig. 1～Fig. 2 as can be known, this motor tire deficency and wheel warning device for looseness thereof, mainly by buzzing indicating device (9), baroswitch (10), conducting ring (11), carbon brush component (12) and contactless switch (13) are formed, buzzing indicating device (9) places in the operator's compartment, buzzing indicating device (9) is by lead and carbon brush component (12), conducting ring (11) joins, carbon brush component (12) and the contactless switch (13) that is installed on the carbon-brush holder are fixed on the brake disc, conducting ring (11) is installed on the wheel hub, and link to each other with baroswitch (10) with lead, baroswitch housing (6) is fixed on the bottom of valve inside (8) and is installed in the valve tube (7).Buzzing indicating device (9) has a plurality of indicator lamps, the indicator lamp that is respectively power light, the loosening indicator lamp of wheel and shows corresponding tire deflation, carbon brush component (12) and contactless switch (13) are received the positive pole of storage battery on the automobile by lead by corresponding indicator lamp respectively, and another is vehicle body very; It is normal to need only the tire internal gas pressure, then the always separated attitude of cylinder (1) and valve inside thimble.In case tyre leakage, the interior air pressure of housing descends, and then spring (4) drives to move with the valve inside thimble on the cylinder (1) and contacts, and constitutes the loop by conducting ring (11), and buzzing indicating device (9) is gone up the luminous and warning corresponding to the indicator lamp of deficency wheel; When the bearing on the automotive wheel, when axle cap damages; it is loosening that car changes; the loosening in motion wheel of automobile joins contactless switch (13) and conducting ring (11); the conducting loop; the then luminous simultaneously and warning of the loosening indicator lamp of the indicator lamp of corresponding wheel and wheel on the buzzing indicating device; make the driver can in time find the gas leakage of tire and becoming flexible of wheel,, protected motor tire and traffic safety effectively so that in time take its corresponding measures.
