There is a dismissal that cannot be.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 필요에 따라 실차 상당의 상사(相似)시뮬레이션이 가능하도록 함으로써, 실험실내에서의 파워트레인 평가가 가능하고, 구동부의 입력을 필요에 따라 조절할 수 있으며, 각 부위의 효과 파악이 가능하도록 하여 효과적인 평가가 이루어질 수 있도록 한 차량의 파워트레인 평가방법을 제공하려는 것이다.Therefore, the present invention has been made to solve the above problems, the object of the present invention is to enable the simulation of the equivalent of the actual vehicle, if necessary, it is possible to evaluate the power train in the laboratory, The input can be adjusted as needed, and the purpose of the present invention is to provide a method for evaluating a power train of a vehicle so that an effective evaluation can be made by identifying effects of each part.
이를 실현하기 위하여 본 발명은 출력을 가변할 수 있는 구동모터를 실차 엔진 대신으로 사용하고, 상기 구동모터와 변속기 사이, 그리고 상기 변속기와 드라이브 샤프트 사이에 각각 토오크 메터를 배치하고, 액슬축 각각에는 토오크 메터와 다이나모 메터를 설치하여 이들 토오크 메터와 다이나모 메터를 메인장치와 전기적으로 연결하여 구동휠에 걸리는 부하에 따른 파워트레인의 각부분에 걸리는 토오크를 측정하여 파워트레인을 평가할 수 있는 차량의 파워트레인 평가방법을 제공한다.In order to realize this, the present invention uses a drive motor having a variable output in place of the actual vehicle engine, and a torque meter is disposed between the drive motor and the transmission, and between the transmission and the drive shaft, respectively, and each torque shaft has a torque meter. By installing meters and dynamometers, these torque meters and dynamometers are electrically connected to the main unit to measure the torque applied to each part of the powertrain according to the load on the drive wheels. Provide a method.
이하, 상기의 목적을 구체적으로 실험할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically test the above object will be described in detail.
도면은 본 발명의 실시하기 위한 평가장치의 2차원적인 구성도를 도시한 것으로서, 본 발명은 실차를 사용하는 것이 아니라 파워트레인의 각 연결부에 해당부분에 걸릴 수있는 부하를 측정할 수 있는 기기를 설치하고 이의 기기로부터 출력되는 측정치를 메인장치에서 비교 분석하여 디스플레이함으로써, 해당 파워트레인을 평가할 수 있도록 한 것이다.The figure shows a two-dimensional configuration diagram of the evaluation apparatus for carrying out the present invention, the present invention is not using a real vehicle, but rather a device capable of measuring the load that can be applied to each part of the connection of the powertrain By installing and displaying the measured values output from the device by comparing and analyzing them on the main device, the corresponding power train can be evaluated.
즉, 실차에 적용되는 엔진 대신에 구동모터(2)를 사용하되, 이의 구동모터(2)는 출력을 필요에 따라 가변할 수 있다.That is, the drive motor 2 is used instead of the engine applied to the actual vehicle, the drive motor 2 thereof can vary the output as needed.
그리고 상기 구동모터(2)의 출력부에는 제1토오크 메터(4)를 개재시켜 실차 변속기(6)를 연결하였으며, 상기 변속기(6)와 제1드라이브 샤프트(8)사이에 제2토오크 메터(10)를 배치하였다.In addition, the output of the drive motor 2 is connected to the actual vehicle transmission 6 via a first torque meter 4, and a second torque meter between the transmission 6 and the first drive shaft 8. 10) was placed.
상기에서 제1토오크 메터(4)는 구동모터(2)에서 출력되는 토오크를 측정하고, 제2토오크 메터(10)는 변속기(6)에서 출력되는 토오크를 측정하게 된다.In the above, the first torque meter 4 measures the torque output from the drive motor 2, and the second torque meter 10 measures the torque output from the transmission 6.
그리고 제1디프렌셜(12)의 좌우측으로 연결되는 액슬(14)(16)에는 각각 제3, 4토오크 메터(18)(20)와 제1, 2다이나모 메터(22)(24)를 배치하였다.The third and fourth torque meters 18 and 20 and the first and second dynamometers 22 and 24 are disposed on the axles 14 and 16 connected to the left and right sides of the first differential 12, respectively. It was.
상기에서 제3,4 토오크 메터(18)(20)는 양 액슬(14)(16)에 걸리는 토오크를 측정하며, 제1,2 다이나모 메터(22)(24)는 양 액슬(14)(16)에 실험에 필요한 부하를 걸어주게 된다.In the above, the third and fourth torque meters 18 and 20 measure the torque applied to both axles 14 and 16, and the first and second dynamometers 22 and 24 measure both axles 14 and 16. ) Is the load required for the experiment.
또한, 상기 제1,2,3,4 토오크 메터(4)(10)(18)(20)와, 제1,2 다이나모 메터(22)(24)는 각각 메인장치(26)와 전기적으로 연결되며, 이의 메인장치(26)에서는 상기 기기로부터 입력되는 신호를 비교 분석하여 디스플레이하게 된다.In addition, the first, second, third and fourth torque meters (4) (10) (18) (20) and the first and second dynamometers (22) and (24) are electrically connected to the main device (26), respectively. The main device 26 of the main device 26 compares and displays a signal input from the device.
이에 따라 실험자는 메인장치(26)로부터 디스플레이되는 측정치에 따라 피 실험 파워트레인을 평가하게 되는 것이다.Accordingly, the experimenter evaluates the test power train under test according to the measurement value displayed from the main device 26.
상기와 같은 평가방법은 4×2 차량의 파워트레인을 평가할 때 이용되는 것이며, 만약 6×4 차량의 경우에 있어서는 상기 디프렌셜(12)이 후측으로 연결되는 제2 드라이브 샤프트(28)에 제5 토오크 메터(30)와 제3 다이나모 메터(32)를 설치하면 된다.The above evaluation method is used when evaluating a power train of a 4x2 vehicle, and in the case of a 6x4 vehicle, the differential 12 is applied to a second drive shaft 28 connected to the rear side. 5 Torque meter (30) and the third dynamometer (32) can be installed.
상기에서 6×4의 차량에 있어서, 상기 4×2의 차량과 같이 미도시한 제2 디프렌셜과 액슬을 생략하고, 제2 드라이브 샤프트(28)에 제5 토오크 메터(30)와 제3 다이나모 메터(32)를 배치한 것은 각각에 설치한 것과 동일한 측정치를 얻을 수 있는 바, 경비절감 차원에서 생략한 것이다.In the 6x4 vehicle, the second differential and the axle, which are not shown as in the 4x2 vehicle, are omitted, and the fifth torque meter 30 and the third drive shaft 28 are omitted from the second drive shaft 28. The arrangement of the dynamometers 32 provides the same measurements as those installed in each bar, and is omitted in terms of cost reduction.
상기와 같은 평가방법에 의하면 피 측정 파워트레인의 각 연결 부위마다 이의 전측으로부터 출력되는 토오크를 측정하고, 각 구동휠측에 각 조건에 알맞는 부하를 걸어줌으로써, 현재 상황에서 각 연결부에 걸리는 토오크를 측정하여 파워트레인의 내구성 등을 종합평가할 수 있게 된다.According to the evaluation method as described above, the torque output from the front side of each connection part of the power train to be measured is measured, and the torque applied to each connection part in the current situation is measured by applying a load suitable for each condition to each driving wheel side. Thus, the durability of the power train and the like can be comprehensively evaluated.
이에따라 파워트레인의 평가를 종래와 같이 각 부품에 측정기기를 설치하고, 실차의 상태로 주행하면서 측정을 하지 않아도 된다.Accordingly, it is not necessary to measure the power train while measuring devices are installed in each component as in the prior art, and the vehicle is operated in the state of the actual vehicle.
그리고 필요에 따라 실차 상당의 상사(相似) 시뮬레이션이 가능하여 실험실내에서의 파워트레인 평가가 가능하며, 구동부의 입력을 필요에 따라 조절할 수 있는 바, 여러조건하에서의 각 부위의 효과 파악이 가능하도록 하여 효과적인 평가를 내릴 수 있는 발명인 것이다.In addition, it is possible to simulate the similarity of the actual vehicle if necessary, and to evaluate the power train in the laboratory, and to adjust the input of the driving part as necessary, so that the effect of each part can be understood under various conditions. It is an invention that can make an effective evaluation.
