Description

타이어의 동접지압 측정장치{Tire contact pressure measuring device}Copper contact pressure measuring device for tires

본 발명은 타이어의 동접지압을 측정할 수 있는 장치에 관한 것으로, 더욱 상세하게는 타이어의 접지압을 독립된 공압 발생 원통관들을 통하여 각각 측정하므로 정확한 접지압을 측정할 수 있는 타이어의 동접지압 측정장치에 관한 것이다.The present invention relates to a device capable of measuring the copper ground pressure of the tire, and more particularly, to a copper ground pressure measuring device capable of measuring accurate ground pressure because the ground pressure of the tire is measured through independent pneumatic cylinders. will be.

주지된 바와 같이 타이어의 접지압은 타이어의 기본적 성능에 큰 영향을 주는 인자에 해당하는데, 이는 타이어 접지부의 단위 면적당 걸리는 하중을 말한다.As is well known, the tire ground pressure corresponds to a factor that greatly affects the basic performance of the tire, which refers to the load applied per unit area of the tire ground portion.

즉, 타이어의 접지형상 및 접지압 분포에 따라서 타이어의 마모성능이나 차량의 연비, 주행 안정성 등이 결정되므로, 타이어의 접지압 분포는 타이어 형상 및 특성을 결정하는 중요한 기준 요인이다.That is, since tire wear performance, fuel economy, running stability, etc. of the tire are determined according to the tire folding shape and the ground pressure distribution, the tire ground pressure distribution is an important reference factor for determining the tire shape and characteristics.

따라서 타이어의 접지압 분포는 이상적으로 측정할 수 있는 방안이 종래에도 다방면으로 연구되어 왔다.Therefore, the method of ideally measuring the ground pressure distribution of the tire has been studied in various ways.

종래 타이어의 접지압 측정장치 중 일본 공개특허 제2006-226778호는 최소형 압력센서들을 매설하여 접지압을 측정하고 있으며, 또한 다른 기술인 일본 공개특허 제2009-085621호는 응력 발광판을 통하여 타이어의 접지압을 측정하였다.Japanese Patent Laid-Open Publication No. 2006-226778 measures the ground pressure by embedding the smallest pressure sensors, and another technique, Japanese Patent Laid-Open Publication No. 2009-085621, measures the tire ground pressure through a stress light emitting plate. It was.

그러나 전자인 압력센서들을 이용하여 타이어의 접지압 측정장치는 전극을 이용한 관계로 설비의 내구성과 강도가 보강되지 않는 단점과 타이어 접지압 측정시 10㎞/h 이하의 저속으로 주행하는 타이어의 동접지압 측정에서는 그리 큰 문제점이 없지만, 고속 주행시 동접지압 측정에서는 노면과 슬립이 발생하여 타이어의 접지면 형상이나 접지압 분포를 측정할 수 없다는 문제점이 있었다.However, the ground pressure measuring device of the tire using electronic pressure sensors has the disadvantage that the durability and strength of the equipment are not reinforced due to the use of electrodes, and the copper ground pressure measurement of tires traveling at low speeds of 10 km / h or less when measuring the tire ground pressure. Although there is no big problem, in the ground contact pressure measurement at high speed, there was a problem that the road surface and slip occurred, so that the tire ground surface shape and the ground pressure distribution could not be measured.

그리고 후자인 판유리처럼 하나의 압력 발광판을 이용한 타이어의 접지압 측정장치는 압력 발광판의 간섭에 의해 접지한 부분 주위로 간섭이 발생하여 접지압을 왜곡시킬 수 있기 때문에 정확한 접지압 분포를 얻을 수 없는 단점이 있었다.In addition, as the latter plate glass, the ground pressure measuring device of the tire using a single pressure light emitting plate may cause interference around the grounded portion due to the interference of the pressure light emitting plate, which may distort the ground pressure. there was.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 발명된 것으로, 주행하는 타이어의 동접지압을 공기압을 발생시키는 동일한 펌핑 구조를 가지는 여러 개의 공압 발생 원통관을 통하여 각각 측정하므로 보다 정확한 타이어의 접지압이 측정되는 타이어의 동접지압 측정장치를 제공함에 그 목적이 있다.The present invention has been invented in view of the above-described conventional problems, and the ground pressure of the tire is measured more precisely because the copper ground pressure of the running tire is measured through a plurality of pneumatic generating cylinders having the same pumping structure to generate air pressure. It is an object of the present invention to provide a device for measuring the ground pressure of the tire.

상기와 같은 목적을 달성하기 위한 본 발명은 주행하는 타이어의 트레드가 접지하는 얇은 접지판과, 상기 얇은 접지판의 하면과 일체로 연결되어 공기통로를 가지는 다수 개의 동일한 구조의 공압 발생 원통관들로 이루어진 공압 발생부, 상기 공압 발생 원통관을 통하여 가해지는 공기압을 측정하는 공기압 측정센서 및, 이 공기압 측정센서에서 보내진 측정신호를 수신하여 판독하는 측정부로 이루어져 있다.The present invention for achieving the above object is a thin ground plate which is grounded by the tread of the running tire, and a plurality of pneumatic generating cylinder tubes of the same structure having an air passage connected integrally with the lower surface of the thin ground plate It is composed of a pneumatic generating unit, an air pressure measuring sensor for measuring the air pressure applied through the pneumatic generating cylinder tube, and a measuring unit for receiving and reading the measurement signal sent from the air pressure measuring sensor.

이러한 본 발명에 따른 타이어의 동접지압 측정장치는 독립된 공압 발생 원통관의 공기압을 통하여 타이어 접지압을 각각 측정하므로 보다 정확한 타이어 접지압을 측정할 수 있는 기능을 갖추게 된다.The apparatus for measuring the earth pressure of a tire according to the present invention measures the tire ground pressure through the air pressure of the independent pneumatic cylinder, so that the tire ground pressure can be measured more accurately.
