Description

The two-wheel tyre flat alarm device

The utility model relates to a kind of vehicle tyre deflation warning system, particularly a kind of two-wheel tire air-leaking alarming device that is used for various two-wheels drivings and two-wheel tractor-trailer.

At present, two-wheel drive and the two-wheel tire of two-wheel tractor-trailer on all be not provided with leak alarm, its weak point is former thereby when leaking gas because of pricking nail etc. when the two-wheel tire, gas leakage sound is slight, chaufeur is difficult for discovering; In case chaufeur is perceived gas leakage, this moment vehicle should not continue the operation, if near do not have automobile repair department, make maintenance more the difficulty; Quick-fried tire is very easily pressed in particularly when heavy duty single-wheel operation of bearing a heavy burden, sometimes in addition two-wheel scrap, make inclination of vehicle in the road.For fear of the generation of above-mentioned situation, chaufeur has to often stop check, between both having mistaken, very bothers again, has also disperseed the energy of chaufeur.So people have designed two-wheel tire flat remote control alarming unit, its weak point is that price is too high, is not suitable for applying on the particularly privately held vehicle of most of vehicle.

The purpose of this utility model is exactly that a kind of simple in structure, easy to install, two-wheel tyre flat alarm device that leakage alarm is effective is provided at above-mentioned weak point.

Technical solution of the present utility model is: a kind of two-wheel tyre flat alarm device, it is characterized in that: form by squeezer, pipe expansion joint and conductor three parts, wherein, squeezer is for being fixed in " U " shape elastic clip between the two-wheel tire, and two clamping bars of this elastic clip are provided with a leverage.Pipe expansion joint is provided with rotatable tongue piece and the pulley that resets for being fixed in the double hull at place, wheel steel ring outer in its interlayer, this tongue piece is connected with an end of flexible axle backguy, and the flexible axle backguy other end passes pulley and is connected with leverage.Conductor is for being fixed in the housing on the brake disc and being fixed on this housing the rotatable lever contactless switch that resets and position adjusting mechanism, bonding copper sheet, and this lever contactless switch one end matches with tongue piece, and the insulator of the other end is provided with the live wire earth connecting contact.

The utility model is by squeezer, pipe expansion joint and conductor constitute, because squeezer is fixed between two tires of two-wheel tire, pipe expansion joint is fixed on place, wheel steel ring outer, adopt the flexible axle backguy to be connected between squeezer and the pipe expansion joint, and with wheel, conductor is fixed on the brake disc, adjustment makes lever contactless switch one end of conductor match with the tongue piece of pipe expansion joint, thereby, after certain tire of two-wheel tire leaks air, its tyre inner pressure reduces gradually, spacing between the place, two tire outers is reduced, force squeezer two clamping bars to shrink, the leverage action, tongue piece in the pipe expansion joint is pulled out, when the distance of pulling out reaches setting value, tongue piece periodically drives the lever contactless switch transmission of conductor in the wheel process, lever contactless switch other end live wire earth connecting contact periodically contacts with the bonding copper sheet, when live wire connect loudspeaker, chaufeur then can be heard " toot " sound of interruption, judged that tire has begun gas leakage, can stop immediately and take corresponding measure or arrive near the place under repair of vehicle maintenance and repair part rapidly, therefore, can avoid tire, also ensure the safety of vehicle operating because of the damage that the gas leakage heavy burden causes.The utlity model has simple in structurely, install, easy to use, cheap, the leakage alarm good effectiveness, overcome the deficiencies in the prior art part, thereby reached its intended purposes, be particularly suitable on the vehicle that two-wheel drives and two-wheel is pulled, applying.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of the utility model squeezer part;

Fig. 2 is the structural representation of the utility model pipe expansion joint part;

Fig. 3 is the structural representation of the utility model conductor part.

The utility model is described in further detail below in conjunction with accompanying drawing: as Fig. 1, Fig. 2, shown in Figure 3.Squeezer comprises " U " shape elastic clip 1, and its top is provided with the fixed link hole 4 that is made of steel pipe that is used for fixing, and the strong point of lever 3 and an end are separately fixed on the contiguous block 6 and contiguous block 2 of two clamping bars, and the other end is connected with flexible axle backguy 5.Lever 3 and contiguous block 6,2 constitute leverage.Squeezer can be fixed on by the fixed link that an end buckle, the other end have block and a nut on the steel ring between the two-wheel tire, and following the correcting of two clamping bars is on the outstanding position, two tire outers.When a certain tire deflation, when squeezer forwarded bottom (near ground) to tire, this moment, tyre surface broadened, and the compressing squeezer inwardly closes up, 2,6 relative motions of two contiguous blocks, lever 3 pulling flexible axle backguys 5.

Pipe expansion joint comprises a double hull 8, and tongue piece 9 is fixed on by rotating shaft in the mezzanine space of housing 8, is provided with retracing spring 7 altogether, and tongue piece 9 is connected with the other end of flexible axle backguy 5.Housing 8 is provided with is convenient to the pulley that backguy 5 is moved.The both sides of housing 8 are provided with draw-in groove, match with the pipe expansion joint fixed mount.The pipe expansion joint fixed mount is fixed on place, wheel steel ring outer, and housing 8 can conveniently insert the pipe expansion joint fixed mount or extract from the pipe expansion joint fixed mount.When flexible axle backguy 5 was spurred by lever 3, tongue piece 9 was drawn out housing 8.

Conductor comprises housing 11, lever contactless switch 13, retracing spring 12, position adjusting mechanism 14, bonding copper sheet 15.Housing 11 is fixed on the other screw of brake disc camshaft through its notch 10 places.Lever contactless switch 13 is fixed on the housing 11 through rotating shaft, which is provided with retracing spring 12.Live wire earth connecting contact 16 is fixed on the termination insulator of lever contactless switch 13.Position adjusting mechanism 14 can be made of adjusting screw(rod) 14, is used for the position relation between adjustment (adjusting) lever contactless switch 13 and the tongue piece 9.Electric wire 17 1 ends are connected with live wire earth connecting contact 16, and the other end is connected with horn trumpet, also can be connected with buzzer phone or the pilot bulb that other joins.Stretch out the position of setting when tongue piece 9 after, it is just hung with lever contactless switch 13 mutually with wheel, drives its rotation, live wire earth connecting contact 16 is contacted with bonding copper sheet 15, and loudspeaker send interrupted sound.Tire pressure is low more, and sound is big more.

The utility model belongs to linkage, tests heavily loaded works very well through being installed on the dongfeng truck trailing wheel.Under normal circumstances, heavy-duty vehicle also sends a chimes of doom once in a while through scraggly highway section, is that another takes turns practicable because one take turns unsettledly through observation.The changing of tire test is installed the utility model and is no more than five minutes.
