Abstract
The utility model relates to an automatic alarming device for tires, which comprises a casing body. The utility model is characterized in that a pressure sensor for the inner tire pressure difference of a tire is arranged in the casing body; a power supply contact connected with the pressure sensor is arranged in the casing body and is connected with an electric brush through conducting wires, and the electric brush is arranged on a braking basin; an electric brush slide ring which is corresponding to the electric brush is arranged on the inner side of a braking baffle plate assembly, wherein, the electric brush, the braking basin, the slide ring and the braking baffle plate are insulated mutually; the electric brush slide ring is connected with an alarm in a steering room through conducting wires again. The utility model transfers pressure difference signals to the steering room through electric brush structure for alarm to output the pressure difference signals under the state of the high speed rotation of wheels. The utility model has the advantages of simple structure, low cost, long service life, etc.
Description
The utility model belongs to the automobile tyre technical field, specifically a kind of tire autoalarm of transport truck.
As everyone knows, the progress of society, constant development of economy be to be unable to do without transit industry, and road haulage industry occupies critical role.As longer distance transportation, mainly based on large-scale transport truck, large trailer, in transportation, often let out the vapour phenomenon because of indivedual tires can take place various factors, if untimely discovery will be made thing, even the major traffic accidents of car crash can take place.In recent years, the technical personnel of some traffic department had been devoted to address the above problem always, also several schemes of Xing Chenging, but because also there are problems in its reliability and sensitieness, so do not promoted always.
The purpose of this utility model provides a kind of tire autoalarm that utilizes the pressure reduction of tire inner tube through the sensor warning.
The purpose of this utility model is achieved in that it includes a metal shell, it is characterized in that being provided with in metal shell a tire inner tube pressure differential pressure sensor, also is provided with a power contact that is connected with pressure sensor on housing; This power contact by lead be arranged on the brush of braking on the basin and be connected, be provided with in the inboard of brake baffle assembly one with the corresponding electric brush slip ring of brush, its center brush and braking basin and electric brush slip ring and brake baffle assembly mutually insulated, electric brush slip ring by lead again with operator's compartment in annunciator join.The concrete structure of above-mentioned pressure sensor is: the base plate of metal shell one side is provided with a through hole, in housing, be provided with the pressure mandril that an end can lean out through hole, middle part at pressure mandril is set with pressure spring, rear portion at push rod is provided with pressure switch contact, on housing, also be provided with one with the corresponding power contact of pressure switch contact, this power contact and pressure switch contact have constituted the pressure switch of sensor.This structure is opened a small sircle hole with the wheel rim middle part of steel plate earlier when mounted, then metal shell is fixedly installed on this position, and the pressure mandril part that wherein leans out housing is corresponding with small sircle hole.When tyre inner pressure just often, its tire internal pressure is when being sleeved on the pressure spring pressure of pressure mandril, then pressure mandril is ejected or pushes up flat small sircle hole by liner mouth skin, this moment, pressure switch was in opening; When car produces gas leakage when moving, then the tire internal pressure reduces, and when its pressure during less than pressure spring pressure, then pressure mandril ejects liner mouth skin to the inner tube of a tyre one side, this moment, pressure switch was in closure state, and then this signal makes alarm equipment alarm by lead, brush and electric brush slip ring.
The other end that the utility model is included in housing internal pressure push rod is provided with the pressure switch compensator spring; Also be included in the brush peripheral sleeve one insulating support is housed, be provided with a brush compensator spring in the inboard of insulating support.
The utility model is owing to be fixed on pressure sensor on the wheel rim of steel plate, and pressure difference signal is directly passed to alarm equipment alarm in the operator's compartment by the brush structure, therefore, make the driver take mistake to execute rapidly, the further damage of generation that avoids traffic accident and locomotive has fundamentally solved wheel and under the high speed revolution state pressure difference signal has been entered the operator's compartment warning continuously by lead.This structure dispense with outer connecting power can directly adopt battery feed just can implement.That the utility model also has is simple in structure, easy to install, be convenient to maintenance, safe and reliable, advantages such as cost is low, long service life.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a pressure sensor sectional structure simplified schematic diagram of the present utility model
Fig. 2 is a brush structure sectional structure simplified schematic diagram of the present utility model
Shown in Fig. 1-2, among the figure 4 is the metal shell of pressure sensor, the base plate 2 of metal shell 4 one sides is provided with a through hole 3, in housing, be provided with the pressure mandril 1 that an end can lean out through hole, be set with pressure spring 5 at the middle part of pressure mandril 1, be provided with pressure switch contact 6 at the rear portion of push rod 1, then the other end of pressure mandril 1 is provided with pressure switch compensator spring 7 and banking stop 8 in housing, on housing 4, also be provided with one with pressure switch contact 6 corresponding power contacts 9, this power contact and pressure switch contact have constituted the pressure switch of sensor.Above-mentioned power contact 9 by lead be arranged on the brush 11 of braking on the basin 10 and be connected, the peripheral sleeve of this brush 11 is equipped with an insulating support 12, is provided with a brush compensator spring 13 in the inboard of insulating support 12; In the inboard of brake baffle assembly 14 by slip ring spider 16 be provided with one with brush 11 corresponding electric brush slip rings 15, its center brush passes through insulating support 12 and slip ring spider 16 mutually insulateds with braking basin and electric brush slip ring and brake baffle assembly, electric brush slip ring again by lead again with operator's compartment in annunciator join.This structure has the small sircle hole about 0.5 sq cm earlier when mounted in the middle part of the wheel rim with steel plate, then metal shell 4 is fixedly installed on this position, and the pressure mandril part that wherein leans out housing is corresponding with small sircle hole.When tyre inner pressure (being generally every sq cm 8-10 kilogram pressure) just often, its tire internal pressure is during greater than the pressure spring pressure that is sleeved on pressure mandril 1 (setting 6 kilograms of pressure of every sq cm), then the pressure in the tire ejects pressure mandril or push up flat small sircle hole by liner mouth skin, and this moment, pressure switch was in opening; When car produces gas leakage when moving, then the tire internal pressure reduces, when its pressure during less than pressure spring pressure, then pressure mandril ejects (Fig. 1 indicating status) with liner mouth skin to the inner tube of a tyre one side, this moment, pressure switch was in closure state, and then this signal makes alarm equipment alarm by lead, brush and electric brush slip ring.Above-mentioned structure is installed on each wheel, and the lead of being drawn from each tire power up brush slip ring together is connected with annunciator in the operator's compartment after parallel connection, when reporting to the police, the driver gets off just can find the tire of gas leakage.
