Description
Technology neck city
The utility model relates to the tyre steel wires and curtain thread tension sensor of a kind of sensor, particularly vehicle, is applicable to the radial that adopts all-steel cord.
Background technology:
The measurement of cord load is one of most important field in the experimental study in the tire industry.Carried out the research of this direction both at home and abroad, but also not relevant patent issue.R.G.Patterson, S.K.Clark and R.N.Dodge and J.D.Walter once used impedance foil strain measuring appliance (foil gauge) to make small-sized force transducer, this sensor can directly be measured the load of the cord in the tire under the ruuning situation, also can put into one by one with cord, embedding when tire building, they can supply with the electric signal that can monitor, to measure the tyre cord load.Clark and Dodge (" Tire Stressand Deformation ", in " Mechanics of Pneumatic Tire ", Ed.Clark, S.K., U.S.DTNHTSA, 1981) force transducer of Cai Yonging is the long thin-walled beryllium copper pipe of 1.27cm, and tyre cord is bonding and pass it with it, use this instrument different load with in depress the innermost layer cord expansion force of having measured two-layer and four layers of tyre crown, tire shoulder and sidewall.The load sensor that Walter (Tire Sci.Techn., 3,2,67 (1975)) adopts is the aluminium alloy fracture of wire of a rectangular cross section, the power in this alloy silk mean allocation tire on two adjacent cord.This class sensor is mostly little than other folder formula measuring appliances.The electrometric sensor that tire tyre cavity cord load is measured by China is to paste foil gauge with rectangle billet stereotype to form (" rubber industry handbook the 6th fascicle ", Chemical Industry Press, 1977), but which kind of foil gauge explanation does not use.These measuring appliances or sensor are mainly used in the curtain line tension or the load measurement of oblique tire casing ply.At present, also there are not correlative study and report propose to measure the sensor of all-steel cord tension force in the tire or load.
The utility model content:
The utility model purpose is a kind of tyre steel wires and curtain thread tension sensor that adopts all-steel cord to provide as framework material in a large number at present radial-ply tyre, embed tire with all-steel cord during tire building, can export one after the tire building sulfuration has repeatability and electric signal that monitor easily, be used to measure the tyre cord load, for an other approach is opened up in intelligent tire research.
For the utility model that achieves the above object provides a kind of tyre steel wires and curtain thread tension sensor, this tyre steel wires and curtain thread tension sensor comprises: u type elastic beam, be installed in the sensor circuit that contains four semiconductor strain gauges on the elastic beam surface, be welded on the lead on the sensor circuit, two sections all-steel cords that pass elastic beam two ends aperture respectively, be placed on behind the above unit construction in the steel bushing, lead and all-steel cord pass from the steel bushing two ends, be full of flexible glue in the steel bushing, the two ends epoxy sealing.The utility model can embed tire, draws lead and is connected with testing apparatus, and the curtain line tension that can obtain under the dynamic and static loading of tire changes.
Of the present utility model being characterised in that, u type elastic beam is made by the high resiliency steel, and pawl place in two ends opens aperture;
Of the present utility model being characterised in that, elastic beam two ends aperture is used for fixing respectively the position of two sections all-steel cords, and all-steel cord passes aperture, is burnt till coccoidly by gas welding in the inboard, snaps in and be welded on the aperture inboard;
Feature of the present utility model also is, other has a circular steel cover and is enclosed within elastic beam, steel wire and wire interconnecting piece position and is used for protection, and whole position can not damaged in tire processing and manufacturing process;
Feature of the present utility model also is to be full of flexible glue between steel bushing and elastic beam, and epoxy sealing is used in steel bushing two ends outlets, can avoid rubber to be pressed into steel bushing well like this, thus being connected between guardwire and sensor circuit;
Feature of the present utility model also is to adopt semiconductor gauge to form the sensor circuit bridge circuit, makes the elastic beam size can reduce to 10mm * 3mm * 3mm, to satisfy test request and to Embedded Division position influence minimum.
Advantage of the present utility model is:
(1) adopt all-steel cord as leading the power element, can parallelly with all-steel cord imbed the tire texture test position, the similar mechanical of its performance makes the tension variation of the more accurate reflection actual tire of test result all-steel cord;
(2) adopt u type elastic beam structure, all-steel cord and elastic beam are connected firmly, the power transmission is reliable;
(3) adopting molten steel silk cord termination is the spherical spot-welding technology that adopts again, guarantees that all-steel cord is fixed on the beam, and adding additives is bonding firmly;
(4) semiconductor strain gauge of the anti-160 degree high temperature of employing makes the whole sensor volume little, and temperature tolerance is good;
(5) adopt steel bushing to protect whole elastic beam and lead-in wire and connecting portion, can make sensor stand test under many bad working environments conditions;
(6) adopting the cable of the anti-160 degree high temperate zone shielding of four-core is signal transmission wire, the shielding line of cable end position is hinged on the all-steel cord, make cable can not cause the junction to disconnect and lost efficacy being subjected to moving under the tensile force effect, thus the signal stabilization transmission after realization tire building and the sulfuration;
(7) adopt flexible glue to fill and epoxy sealing, can guarantee in the tire vulcanization process, can not clamp-on steel bushing and cause the sensor actual effect because rubber flows.
