도 1 을 참조하면, 본 발명에 따른 실차 조건 테스트장치는 전기차에 이용되는 감속기(100)를 실차 조건으로 테스트하기 위한 장치로서, 전기차용 감속기(100)에 착탈 결합되어 감속기(100)에 회전력을 인가하기 위한 구동력인가모터부(50)와, 상기 감속기(100)에 착탈 결합되어 감속기(100)의 회전력을 전달받기 위한 출력모터부(60)와, 상기 감속기에 착탈 결합되는 센서부(70)와, 상기 센서부(70)와 구동력인가모터부(50)에 연결되는 제어부(80)를 포함하며, 상기 감속기(100)에 착탈 결합되어 감속기(100)의 회전력을 전달받기 위한 출력모터부(60)가 설치되는 것을 특징으로 한다.Referring to FIG. 1 , the actual vehicle condition testing apparatus according to the present invention is a device for testing the reducer 100 used in an electric vehicle under actual vehicle conditions, and is detachably coupled to the electric vehicle reducer 100 to apply rotational force to the reducer 100 . A driving force applying motor unit 50 for applying, an output motor unit 60 detachably coupled to the reducer 100 to receive the rotational force of the reducer 100, and a sensor unit 70 detachably coupled to the reducer and a control unit 80 connected to the sensor unit 70 and the driving force applying motor unit 50, and is detachably coupled to the reducer 100 to receive the rotational force of the reducer 100. An output motor unit ( 60) is characterized in that it is installed.

본 발명에 따른 실차 조건 테스트장치는 전기차에 이용되는 감속기(100)를 실차 조건으로 테스트하기 위해 이용된다.The actual vehicle condition test apparatus according to the present invention is used to test the reducer 100 used in an electric vehicle under the actual vehicle condition.

상기 구동력인가모터부(50)는 테스트 대상인 전기차용 감속기(100)에 착탈 결합되도록 구성된다.The driving force applying motor unit 50 is configured to be detachably coupled to the reducer 100 for an electric vehicle to be tested.

테스트 작업이 시작되면, 상기 구동력인가모터부(50)가 상기 감속기(100)에 결합되어 회전력을 인가한다.When the test operation is started, the driving force applying motor unit 50 is coupled to the speed reducer 100 to apply a rotational force.

테스트 대상물인 상기 감속기(100)에는 도시되지 않은 입력축과 출력축(102)이 설치되는데, 상기 감속기(100)의 입력축에 상기 구동력인가모터부(50)가 결합되어 회전력을 인가하도록 구성된다.An input shaft and an output shaft 102 (not shown) are installed in the reducer 100 as a test object, and the driving force applying motor unit 50 is coupled to the input shaft of the reducer 100 to apply a rotational force.

한편, 상기 감속기(100)의 출력축에는 상기 출력모터부(60)가 결합된다.On the other hand, the output motor unit 60 is coupled to the output shaft of the speed reducer 100 .

그리고, 바람직하게는 상기 출력모터부(60)의 회전 속도가 상기 감속기(100)의 회전 속도와 동일하게 제어된다.And, preferably, the rotation speed of the output motor unit 60 is controlled to be the same as the rotation speed of the speed reducer 100 .

상기 구동력인가모터부(50)에 의해 상기 감속기에 회전력이 인가되는 경우, 상기 감속기(100)의 출력축(102) 회전 속도는 설계치 회전속도가 된다.When a rotational force is applied to the reducer by the driving force applying motor unit 50 , the rotational speed of the output shaft 102 of the reducer 100 becomes the design value rotational speed.

이때, 상기 출력모터부(60)의 회전축과 상기 감속기(100)의 출력축을 연결시킨 상태에서, 상기 감속기(100)의 출력축 회전 속도와 상기 출력모터부(60)의 회전축 회전속도가 동일해지도록 제어된다.At this time, in a state in which the rotation shaft of the output motor unit 60 and the output shaft of the reducer 100 are connected, the output shaft rotation speed of the reducer 100 and the rotation shaft rotation speed of the output motor unit 60 become the same Controlled.

이때, 도 2 에 도시된 본 발명의 다른 실시예에서와 같이, 상기 출력모터부(60)의 회전축과 상기 감속기(100)의 출력축(102) 사이에 회전에 대한 저항력을 제공하기 위한 회전력저항부재(90)가 설치될 수도 있다.At this time, as in another embodiment of the present invention shown in FIG. 2 , a rotational force resistance member for providing resistance to rotation between the rotational shaft of the output motor unit 60 and the output shaft 102 of the reducer 100 . (90) may be installed.

상기 감속기(100)의 출력축(102)에 상기 출력모터부(60)가 결합되어, 감속기(100)의 출력축 회전 속도와 동일한 속도로 회전됨으로써, 상기 감속기(100)의 출력축(102)에 아무런 구성이 연결되지 않아 자유단 회전 상태가 되는 경우와 비교하여, 실제 차량 주행 조건에 매우 유사한 테스트 조건이 된다.The output motor unit 60 is coupled to the output shaft 102 of the reducer 100 and rotates at the same speed as the output shaft rotation speed of the reducer 100, so that the output shaft 102 of the reducer 100 has no configuration Compared to the case where this is not connected and the free-end rotation state is obtained, the test conditions are very similar to the actual vehicle driving conditions.

즉, 전기차의 실제 주행 상태에서는 상기 감속기(100)의 출력축에 자동차의 바퀴 또는 바퀴에 회전력을 전달하기 위한 구성들이 결합되는데, 상기 자동차의 바퀴 또는 바퀴에 회전력을 전달하기 위한 구성 대신, 상기 출력모터부(60)가 결합되어 동일 속도로 회전됨으로써, 마치 실제 자동차의 바퀴 또는 바퀴에 회전력을 전달하기 위한 구성들이 결합된 환경과 매우 유사한 상태가 될 수 있다.That is, in the actual driving state of the electric vehicle, components for transmitting rotational force to the wheels or wheels of the vehicle are combined with the output shaft of the reducer 100. Instead of the configuration for transmitting rotational force to the wheels or wheels of the vehicle, the output motor As the unit 60 is coupled and rotated at the same speed, it may be in a state very similar to an environment in which components for transmitting rotational force to the wheels or wheels of an actual vehicle are combined.

그리고, 상기 회전력저항부재(90)를 상기 출력모터부(60)와 감속기(100) 사이에 매개시킨 상태에서, 상기 출력모터부(60)로써 감속기(100) 출력축(102)과 동일 속도로 회전시킴으로써, 상기 감속기(100)에 가해지는 실제 부하 조건과 동일한 조건이 되도록 할 수 있다.And, in a state in which the torque resistance member 90 is interposed between the output motor unit 60 and the reducer 100 , the output motor unit 60 rotates at the same speed as the output shaft 102 of the reducer 100 . By doing so, it is possible to achieve the same condition as the actual load condition applied to the reduction gear 100 .

상기 제어부(80)는 상기 센서부(70)와 구동력인가모터부(50) 및 출력모터부(60)에 연결되어, 상기 센서부(70)로부터의 감지신호를 수신받고, 상기 구동력인가모터부(50)와 출력모터부(60)의 구동 신호를 송신한다.The control unit 80 is connected to the sensor unit 70, the driving force applying motor unit 50 and the output motor unit 60, receives a detection signal from the sensor unit 70, and the driving force applying motor unit (50) and transmits the driving signal of the output motor unit (60).

상기 센서부(70)는 상기 감속기에 부착 설치되어, 상기 감속기(100)로부터 발생되는 진동을 감지할 수 있도록 진동센서로 구성될 수 있다.The sensor unit 70 may be installed attached to the reducer and configured as a vibration sensor so as to sense vibration generated from the reducer 100 .

그리하여, 상기 감속기(100)에 구동력인가모터부(50)와 출력모터부(60)가 결합된 상태에서, 상기 감속기(100)가 회전되는 때에 발생되는 진동을 감지하여 감속기(100)의 여러가지 성능들을 검사할 수 있다.Thus, in a state in which the driving force applying motor unit 50 and the output motor unit 60 are coupled to the reducer 100 , vibration generated when the reducer 100 is rotated is sensed to provide various performances of the reducer 100 . can be inspected.

그리고, 상기 구동력인가모터부(50)와 출력모터부(60)에는 전원공급부(10)를 통해 공급되는 전력을 상기 구동력인가모터부(50)와 출력모터부(60)의 구동에 적합한 전력으로 변환하기 위한 전력변환부(20, 40)들을 포함한다.In addition, the power supplied through the power supply unit 10 to the driving force applying motor unit 50 and the output motor unit 60 is converted into power suitable for driving the driving force applying motor unit 50 and the output motor unit 60 . It includes power conversion units 20 and 40 for conversion.

그리고, 상기 구동력인가모터부(50)에 결합되는 전력변환부(40)에는, 전기자동차 종류에 따라 달라지는 배터리의 성능 특성을 반영하여 상기 전력변환부(40)로 공급하기 위한 배터리감지제어부(30)가 연결될 수 있다.In addition, in the power conversion unit 40 coupled to the driving force applying motor unit 50, a battery sensing control unit 30 for supplying to the power conversion unit 40 by reflecting the performance characteristics of the battery that varies depending on the type of electric vehicle ) can be connected.
