Description

자동차용 노면 계측 장치Automobile road measuring device

본 고안은 자동차의 주행중 노면에서 바디에 인가되는 충격량을 계측하기 위한 노면 계측 장치에 관한 것이다.The present invention relates to a road surface measuring device for measuring the amount of impact applied to the body on the road surface of the vehicle driving.

일반적으로, 자동차는 고속 주행하는 장치이기 때문에 주행중 노면에서의 충격 흡수, 코너링 시의 안정성 및 출발, 정지시의 차체 안정등이 매우 중요하게 된다.In general, since a vehicle is a device that travels at high speeds, shock absorption on the road surface during driving, stability at cornering and body stability at start and stop are very important.

즉, 노면과 바디 사이에 설치되어 실질적으로 차체를 지지하는 서스펜션이 바디의 롤링, 요잉 등을 최소화시킴과 아울러 노면의 충격을 최대한 흡수하여야 하는 것이다.In other words, the suspension that is installed between the road surface and the body to substantially support the vehicle body should minimize the rolling, yawing, etc. of the body and absorb the impact of the road surface as much as possible.

물론, 상기한 서스펜션의 세팅은 차종에 따라 하드(HARD), 스프트(SOFT)로 조절하게 되는 바, 상기한 서프펜션의 세팅은 차량의 시험 주행 후 노면과의 충격등에 따라 적절하게 조절하게 된다.Of course, the setting of the suspension is adjusted to the hard (HARD), SOFT depending on the vehicle type, the setting of the suspension is appropriately adjusted according to the impact on the road surface after the test run of the vehicle. .

여기서, 상기한 노면과의 충격 관계등을 측정하기 위해서는 소정의 장치가 필요하게 되는 바. 이는 제3도에 도시된 바와 같이 크로스멤버(50)와, 상기한 크로스멤버(50)의 측면에 브라켓(51)으로 고정됨과 아울러 액슬축(52)과 와이어(53)로 연결된 변위계(54)로 구성되어 있다.Here, a predetermined device is required to measure the impact relationship with the road surface. As shown in FIG. 3, the displacement meter 54 is fixed to the cross member 50 and the side of the cross member 50 by the bracket 51 and connected to the axle shaft 52 and the wire 53. Consists of

즉, 주행시 상기한 액슬축(52)의 상하 진동을 상기한 와이어(53)를 통해 변위계(54)가 측정함으로써 노면과 액슬측(52)과의 충격치를 산정하게 되는 것이다.That is, when the displacement meter 54 measures the vertical vibration of the axle shaft 52 through the wire 53 while driving, the impact value between the road surface and the axle side 52 is calculated.

그러나, 상기한 바와 같이 크로스멤버의 측면에 브라켓으로 변위계를 부착함과 아울러 액슬축과 와이어로 연결하게 되면 각각의 시험 차종별로 상이한 사양을 가지게 됨으로써 시험 차종이 변경될 때마다 별도의 장치를 부착해야 하는 불편함이 있다.However, as described above, when the displacement meter is attached to the side of the cross member by the bracket and connected to the axle shaft and the wire, it has a different specification for each test vehicle, so a separate device must be attached every time the test vehicle is changed. There is discomfort.

따라서, 본 고안의 목적은 상기한 문제점을 해결하기 위한 것으로서, 다수의 시험차종에 공용으로 사용할 수 잇는 자동차용 노면 계측 장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, to provide a road surface measuring apparatus for automobiles that can be used in common in a number of test vehicles.

상기한 목적을 실현하기 위하여 본 고안은 휠의 측면에 부착되도록 전자석이 설치됨과 아울러 상기한 전자석에 전류를 공급하기 위하여 스위치가 개재된 상태로 돌출부에 배터리가 내장된 회전부와, 상기한 회전부의 돌출부가 삽입되도록 중앙에 삽입공이 형성됨과 아울러 변위 센서에 연결된 하우징으로 구성함을 특징으로 한다.In order to realize the above object, the present invention is provided with an electromagnet installed to be attached to the side of the wheel, and a rotary unit having a battery built into the protrusion in a state where a switch is interposed to supply current to the electromagnet, and the protrusion of the rotary unit. Insertion is formed in the center so that the insertion is characterized in that the housing is connected to the displacement sensor.

제1도와 제2도는 본 고안에 따른 자동차용 노면 계측 장치를 도시한 분해 사시도와 조립 단면도로서, 휠(W)의 측면에 부착되도록 전자석(1)이 설치됨과 아울러 상기한 전자석(1)에 전류를 공급하기 위하여 스이치가 (2)가 개재된 상태로 돌출부(3)에 배터리(4)가 내장된 회전부(5)와, 상기한 회전부(5)의 돌출부(3)가 삽입되도록 중앙에 삽입공(6)이 형성됨과 아울러 변위 센서(7)에 와이어등으로 연결된 하우징(8)으로 구성되어 있다.1 and 2 are exploded perspective and assembly cross-sectional views showing the road surface measuring apparatus for automobiles according to the present invention, wherein the electromagnet 1 is installed to be attached to the side of the wheel W, and the current is applied to the electromagnet 1. Inserted in the center such that the rotating part 5 with the battery 4 embedded in the protrusion part 3 and the protrusion part 3 of the rotating part 5 are inserted into the protrusion part 3 in a state in which the catch is provided (2). The ball 6 is formed and the housing 8 is connected to the displacement sensor 7 by a wire or the like.

즉, 외부로 노출되어 있는 차량의 휠(W)에 상기한 하우징(8) 및 회전부(5)를 부착하면, 여러종류의 차종에 관계없이 차량 주행시 노면에 의해 휠(W)이 승강 운동할 때의 변위(노면의 높낮이등)를 감지할 수 있게 되는 것이다.That is, when the housing 8 and the rotating part 5 are attached to the wheel W of the vehicle that is exposed to the outside, when the wheel W moves up and down by the road surface regardless of various types of vehicles, It will be able to detect the displacement of the road surface.

상기한 바와 같은 고안의 작용 효과를 설명하면 작업자가 시험 차량의 휠(W)에 회전부(5)를 밀착시킴과 아울러 상기한 스위치(2)를 동작시켜 배터리(4)로부터 전자석(1)에 전류를 공급하게 된다.In describing the operation and effect of the above-described design, the operator makes contact with the rotary part 5 to the wheel W of the test vehicle and operates the switch 2 to operate the current from the battery 4 to the electromagnet 1. Will be supplied.

전자석(1)에 전류가 공급되면 전자석(1)에서 발생되는 자력에 의해 휠(W)과 회전부(5)가 견고하게 결합되는 바, 상기한 결합 후 또는 결합전에 회전부(5)에 하우징(8)이 결합되어 있는 상태가 된다.When the electric current is supplied to the electromagnet 1, the wheel W and the rotating part 5 are firmly coupled by the magnetic force generated by the electromagnet 1, and the housing 8 is connected to the rotating part 5 after the above-mentioned coupling or before the coupling. ) Is combined.

여기서, 상기한 회전부(5)의 돌출부(3)와 하우징(8)의 삽입공(6) 사이에는 도시되지 않는 베어링이 개재되어 회전부(5)의 회전을 원활하게 함과 아울러 원판형의 고정판(9)이 돌출부(3) 종단에 결합되어 상기한 하우징(8)이 분리되지 않도록 한다.Here, a bearing (not shown) is interposed between the protruding portion 3 of the rotating part 5 and the insertion hole 6 of the housing 8 to facilitate the rotation of the rotating part 5 and to have a disc-shaped fixing plate ( 9) is coupled to the end of the protrusion 3 so that the housing 8 is not separated.

즉, 회전부(5)의 돌출부(3)를 하우징(8)의 삽입공(6)에 결합시킨 후 상기한 고정판(9)을 돌출부 종단에 결합시키게 되면, 상기한 하우징98)이 회전부(5)에 위치 제한됨과 아울러 회전 자재할 수 있게 되는 것이다.That is, when the protrusion 3 of the rotary part 5 is coupled to the insertion hole 6 of the housing 8 and then the fixing plate 9 is coupled to the end of the protrusion, the housing 98 is the rotary part 5. In addition to being limited to the position will be able to rotate material.

이 상태에서, 상기한 하우징(8)에 연결된 변위 센서(7)를 차량의 바디에 고정 설치하게 된다.In this state, the displacement sensor 7 connected to the housing 8 is fixed to the body of the vehicle.

여기서, 상기한 회전부(5)는 전자석(1)으로 금속재인 휠(W)에 고정되기 때문에 차종에 관계없이 설치 가능하게 되는 것이다.Here, since the rotating part 5 is fixed to the wheel W, which is a metal material, by the electromagnet 1, it is possible to install regardless of the vehicle type.

이 상태에서 차량이 주행하게 되면, 상기한 휠(W)이 노면의 상태에 따라 승강 운동하게 되고, 상기한 승강 운동에 따른 승강 변위를 와이어가 변위 센서(7)에 전달하게 된다.When the vehicle travels in this state, the wheel W moves up and down according to the road surface state, and the wire transfers the lifting displacement according to the lifting movement to the displacement sensor 7.

변위 센서(7)에 승강 변위가 전달되면 이를 측정함으로써, 노면의 높낮이 상태(프로파일)을 변위 센서(7)가 측정할 수 있게 되는 것이다.When the lift displacement is transmitted to the displacement sensor 7, the displacement sensor 7 measures the height of the road surface so that the displacement sensor 7 can measure the height (profile) of the road surface.

물론, 상기한 와이어는 하우징(8)과 변위 센서(7) 사이에서 팽팽한 상태로 유지되어 있어야 변위의 전달이 가능할 뿐만 아니라 쉽게 구부러지지 않는 강성이 있는 일반적인 와어어로 이루어져 있게 된다.Of course, the wire must be kept taut between the housing 8 and the displacement sensor 7 to allow for the transfer of displacement and to be made of a general stiff wire that is not easily bent.

즉, 와이어가 팽팽하게 당겨진 상태를 유지하게 되면, 상기한 승강에 따른 변위가 변위 센서(7)에 정확하게 전달되고, 하우징(8)이 베어링을 통한 극히 미소한 마찰력에 의해서도 회전되지 않고 고정된 상태를 유지하게 되는 것이다.In other words, if the wire is kept in the tensioned state, the displacement caused by the lifting and lowering is accurately transmitted to the displacement sensor 7, and the housing 8 is fixed without being rotated even by an extremely minute friction force through the bearing. Will be maintained.

이상과 같이 본 고안은 차량의 휠에 부착됨과 아울러 회전되는 회전부에 변위 센서가 연결된 하우징을 결합시킴으로써 차종에 관계없이 설치 가능함과 아울러 노면의 프로파일을 용이하게 측정할 수 이써는 잇점이 있는 것이다.As described above, the present invention is advantageous in that it can be installed regardless of the vehicle type and can easily measure the profile of the road surface by combining the housing connected to the wheel of the vehicle and the displacement sensor connected to the rotating part to be rotated.
