본 발명은 차량의 전동식 파워스티어링 장치(MDPS)에 사용되는 모터를 컴프레서 구동용 모터로 겸용할 수 있도록 한 점에 주안점이 있다.The present invention focuses on the fact that a motor used in an electric power steering apparatus (MDPS) of a vehicle can be used as a compressor driving motor.

전술한 바와 같이, 전동식 파워스티어링 장치는 ECU가 차량속도에 따라 모터 움직임을 제어하여 최적의 조향감을 운전자에게 제공할 수 있도록 한 것으로서, 모터의 구동에 따라 랙 구동형 스티어링샤프트가 좌우로 움직이면서 조향이 이루어진다.As described above, the electric power steering device allows the ECU to control the motor movement according to the vehicle speed so as to provide the driver with an optimal steering feeling. As the motor is driven, the rack-driven steering shaft moves left and right, and steering is performed. Is done.

첨부한 도 2에 도시된 바와 같이, 상기 스티어링샤프트(10)에는 모터(14)의 동력을 감속시켜 스티어링샤프트(10)로 전달하는 감속기어박스(12)의 출력단이 연결되고, 감속기어박스(12)의 입력단에는 조향을 위한 동력을 제공하는 모터(14)가 연결된다.As shown in FIG. 2, the steering shaft 10 is connected to an output end of the reduction gear box 12 which decelerates the power of the motor 14 and transmits the power to the steering shaft 10, and reduces the gear box ( To the input of 12 is a motor 14 which provides power for steering.

상기 모터(14)는 양방향 회전을 하는 모터이면서, 양측단을 통해 제1축 및 제2축이 돌출된 형태로 채택된다.The motor 14 is a motor that rotates in both directions, and the first shaft and the second shaft are protruded through both side ends.

이때, 첨부한 도 1 및 도 2에서 보듯이 상기 감속기어박스(12)의 입력단과 모터(14)의 제1축 간에는 통상의 제1전자클러치(16)가 장착되어, 모터(14)의 동력을 감속기어박스(12)에 전달 또는 해제하는 역할을 하게 된다.At this time, as shown in FIG. 1 and FIG. 2, a normal first electromagnetic clutch 16 is mounted between the input terminal of the reduction gear box 12 and the first shaft of the motor 14 to power the motor 14. It serves to deliver or release to the reduction gear box (12).

보다 상세하게는, 제1전자클러치(16)가 감속기어박스(12)의 입력기어(미도시됨)와 연결된 상태에서, 제1전자클러치(16)에 전류이 인가되면 모터(14)의 제1축으로 제1전자클러치(16)가 이동하여 붙게 됨으로써, 동력 전달이 이루어지는 상태가 되고, 반대로 전류 인가가 해제되면 제1전자클러치(16)는 리턴스프링(미도시됨)의 복원력에 의하여 모터(14)의 제1축으로부터 단락되어 동력 전달이 해제된다.More specifically, when the first electromagnetic clutch 16 is connected to the input gear (not shown) of the reduction gear box 12, when a current is applied to the first electromagnetic clutch 16, the first of the motor 14 is applied. As the first electromagnetic clutch 16 moves and attaches to the shaft, power transmission is performed. On the contrary, when the current is released, the first electromagnetic clutch 16 is driven by a restoring force of the return spring (not shown). The power transmission is canceled by shorting from the first shaft of 14).

한편, 상기 모터(14)의 반대쪽에 돌출된 제2축(28)에는 모터(14)의 동력을 컴프레서(30)쪽으로 전달하는 동력전달기어세트(20)가 연결된다.On the other hand, the power transmission gear set 20 for transmitting the power of the motor 14 toward the compressor 30 is connected to the second shaft 28 protruding from the opposite side of the motor 14.

이때, 모터(14)의 제2축(28)과 동력전달기어셋트(20)의 구동기어(21) 사이에는 모터(14)의 동력을 동력전달기어셋트(20)로 전달 또는 해제하는 제2전자클러치(18)가 장착된다.At this time, between the second shaft 28 of the motor 14 and the drive gear 21 of the power transmission gear set 20, a second for transmitting or releasing the power of the motor 14 to the power transmission gear set 20 The electromagnetic clutch 18 is mounted.

즉, 상기 제2전자클러치(18)에 구동기어(21)의 축이 연결된 상태에서, 제2전자클러치(18)에 전류이 인가되면 모터(14)의 제2축(28)으로 제2전자클러치(18)가 이동하는 동시에 제2전자클러치(18)의 일면 중심에 형성된 연결홈(26)에 각이 진 형태의 제2축(28)이 삽입 결합됨으로써, 모터(14)의 동력이 구동기어(21)로 전달 되는 상태가 되고, 반대로 전류 인가가 해제되면 제2전자클러치(18)는 리턴스프링(미도시됨)의 복원력에 의하여 모터(14)의 제2축(28)으로부터 단락되어 동력 전달이 해제된다.That is, when the shaft of the drive gear 21 is connected to the second electromagnetic clutch 18, when a current is applied to the second electromagnetic clutch 18, the second electromagnetic clutch is moved to the second shaft 28 of the motor 14. As the 18 moves, the angled second shaft 28 is inserted into and coupled to the connecting groove 26 formed at the center of one surface of the second electromagnetic clutch 18, whereby the power of the motor 14 is driven. When the current is released, the second electromagnetic clutch 18 is shorted from the second shaft 28 of the motor 14 by the restoring force of the return spring (not shown). Delivery is released.

여기서, 모터와 컴프레서를 동력 전달 가능하게 연결하는 동력전달기어셋트의 구성을 첨부한 도 3을 참조로 살펴보면 다음과 같다.Here, referring to Figure 3 attached to the configuration of the power transmission gear set for connecting the motor and the compressor to the power transmission as follows.

상기 동력전달기어셋트(20)의 일 구성중, 구동기어(21)의 중심축이 제2전자클러치(18)와 연결되고, 구동기어(21)의 치면에는 제1 및 제2원웨이 베어링(22,23)이 동시에 맞물린다.In one configuration of the power transmission gear set 20, the central axis of the drive gear 21 is connected to the second electromagnetic clutch 18, and the first and second one-way bearings are formed on the tooth surfaces of the drive gear 21. 22, 23) at the same time.

이때, 상기 제1원웨이 베어링(22)에는 컴프레서(30)의 몸체부에 힌지로 연결된 동력전달매개기어(24)가 동축으로 연결되고, 제2원웨이 베어링(23)에는 컴프레서(30)의 입력축과 일체로 연결된 출력기어(25)가 동축으로 연결된다.At this time, the power transmission medium gear 24 connected to the body portion of the compressor 30 by a hinge is connected to the first one-way bearing 22 coaxially, the second one-way bearing 23 of the compressor 30 The output gear 25 integrally connected with the input shaft is connected coaxially.

상기 제1 및 제2원웨이 베어링(22,23)은 마치 자전거의 뒷바퀴 베어링과 같이 한쪽 방향으로만 동력을 전달하는 원웨이 클러치 형태의 베어링으로서, 제1 및 제2원웨이 베어링(22,23)은 서로 다른 일방향으로 회전할 때 동력을 전달하고, 서로 다른 타방향으로 회전할 때 동력을 차단하게 된다.The first and second one-way bearings 22 and 23 are one-way clutch-type bearings which transmit power only in one direction, as in a rear wheel bearing of a bicycle, and the first and second one-way bearings 22 and 23. ) Transmits power when rotated in different directions, and cuts power when rotated in different directions.

즉, 상기 제1원웨이 베어링(22)은 구동기어(21)가 반시계반향으로 회전할 때 동력전달매개기어(24)에 동력을 전달하고, 구동기어(21)가 시계방향으로 회전할 때 공회전하면서 동력을 차단하는 기능을 하며, 또한 상기 제2원웨이 베어링(23)은 구동기어(21)가 시계반향으로 회전할 때 출력기어(25)에 동력을 전달하고, 구동기어(21)가 반시계방향으로 회전할 때 공회전하면서 동력을 차단하는 기능을 한다.That is, the first one-way bearing 22 transmits power to the power transmission medium gear 24 when the drive gear 21 rotates counterclockwise, and when the drive gear 21 rotates clockwise. The second one-way bearing 23 transmits power to the output gear 25 when the drive gear 21 rotates in a counterclockwise direction, and the drive gear 21 When rotating in the counterclockwise direction, it turns off the power while idling.

이때, 상기 동력전달매개기어(24)와 출력기어(25)는 서로 평행하게 배열되어 각 치면이 동력 전달 가능하게 서로 맞물리게 된다.At this time, the power transmission medium gear 24 and the output gear 25 are arranged in parallel to each other is meshed with each other to enable power transmission.

여기서, 상기한 구성으로 이루어진 본 발명의 전동식 파워스티어링 및 컴프레서 일체화 장치에 대한 작동 흐름을 설명하면 다음과 같다.Here, the operation flow for the electric power steering and compressor integration device of the present invention having the above configuration will be described.

첨부한 도 5에 도시된 바와 같이, 본 발명의 전동식 파워스티어링 및 컴프레서 일체화 장치의 작동모드에는 차량의 주행시 조향을 위한 MDPS 작동모드와, 주정차시 에어컨만이 작동하는 에어컨 작동모드와, 조향 및 에어컨이 모두 작동하는 MDPS+에어컨 작동모드가 포함된다.As shown in FIG. 5, the operation mode of the electric power steering and compressor integration device of the present invention includes an MDPS operation mode for steering when the vehicle is driven, an air conditioning operation mode in which only the air conditioner is operated while parking, and steering and air conditioning. This includes the MDPS + air conditioning mode of operation.

상기 MDPS 작동모드는 전동식 파워스티어링 장치에 의한 조향 모드로서, 제1전자클러치(16)에 전류가 인가되어 제1전자클러치(16)가 모터(14)의 제1축과 결합되는 상태가 되고, 제2전자클러치(18)에는 전류가 인가되지 않음에 따라 모터(14)의 동력이 전달되지 않는 상태가 된다.The MDPS operation mode is a steering mode by the electric power steering device, and a current is applied to the first electromagnetic clutch 16 so that the first electromagnetic clutch 16 is coupled to the first shaft of the motor 14. Since no current is applied to the second electromagnetic clutch 18, the power of the motor 14 is not transmitted.

따라서, 모터(14)의 동력이 제1전자클러치(16)를 통하여 감속기어박스(12)로 전달되는 동시에 스티어링샤프트(10)가 감속기어박스(12)의 출력동력을 전달받아 동작함으로써, 모터(14)에 의한 조향이 이루어지게 된다.Therefore, the power of the motor 14 is transmitted to the reduction gear box 12 through the first electromagnetic clutch 16 and the steering shaft 10 receives the output power of the reduction gear box 12 to operate the motor. Steering by 14 is achieved.

상기 에어컨 작동모드는 예를 들어, 전동식 파워스티어링 장치에 의한 조향이 이루어지지 않는 주정차시 에어컨을 작동하였을 때의 작동모드로서, 제2전자클러치(18)에 전류가 인가되어 제2전자클러치(18)가 모터(14)의 제2축(28)과 결합되는 상태가 되고, 제1전자클러치(16)에는 전류가 인가되지 않음에 따라 모터(14)의 동력이 감속기어박스(12)로 전달되지 않는 상태가 된다.The air conditioner operation mode is, for example, an operation mode when the air conditioner is operated when parking is not performed by the electric power steering device, and a current is applied to the second electronic clutch 18 so that the second electronic clutch 18 is operated. ) Is coupled to the second shaft 28 of the motor 14, the power of the motor 14 is transmitted to the reduction gear box 12 as no current is applied to the first electromagnetic clutch 16. It becomes the state that is not.

따라서, 모터(14)의 동력이 제2전자클러치(18)를 통하여 동력전달기어셋트(20)로 전달됨과 함께 컴프레서(30)가 작동하여 에어컨이 작동하게 된다. Accordingly, the power of the motor 14 is transmitted to the power transmission gear set 20 through the second electronic clutch 18 and the compressor 30 is operated to operate the air conditioner.

상기 MDPS+에어컨 작동모드는 조향이 이루어짐과 함께 에어컨이 동시에 작동하는 모드로서, 상기와 같은 MDPS 작동모드 및 에어컨 작동모드가 동시에 이루어지게 된다.The MDPS + air conditioner operation mode is a mode in which the air conditioner operates simultaneously with steering, and the MDPS operation mode and the air conditioner operation mode as described above are simultaneously performed.

여기서, 상기 에어컨 작동모드와, MDPS+에어컨 작동모드에서 컴프레서로 동력이 전달되는 과정을 첨부한 도 4a 및 도 4b를 참조로 좀 더 상세하게 설명하면 다음과 같다.Herein, the air conditioner operation mode and MDPS + air conditioner operation mode will be described in more detail with reference to FIGS. 4A and 4B attached to the process of transmitting power to the compressor.

먼저, 모터(14)가 시계방향으로 회전하며 구동하면, 제2전자클러치(18)를 통해 구동기어(21)로 동력이 전달되는 동시에 구동기어(21)도 모터(14)와 동일한 시계방향으로 회전을 하게 된다.First, when the motor 14 rotates in a clockwise direction, power is transmitted to the drive gear 21 through the second electromagnetic clutch 18 and the drive gear 21 also moves in the same clockwise direction as the motor 14. It turns.

이때, 상기 구동기어(21)에 동시에 맞물려 있는 제1 및 제2원웨이 베어링(22,23)중, 동력전달매개기어(24)와 동축으로 연결된 제1원웨이 베어링(22)은 공회전하면서 동력을 차단하는 역할을 하고, 반면에 제2원웨이 베어링(23)은 반시계방향으로 회전하면서 구동기어(21)의 동력을 출력기어(25)로 전달하게 된다.At this time, of the first and second one-way bearings 22 and 23 which are simultaneously engaged with the drive gear 21, the first one-way bearing 22 coaxially connected to the power transmission medium gear 24 is idling while being powered. The second one-way bearing 23 rotates counterclockwise while transmitting power of the drive gear 21 to the output gear 25.

따라서, 상기 출력기어(25)가 반시계방향으로 회전하면서 컴프레서(30)의 구동이 이루어지게 되어, 에어컨이 작동하게 된다.Therefore, the compressor 30 is driven while the output gear 25 rotates counterclockwise, thereby operating the air conditioner.

한편, 상기 모터(14)가 조향을 위하여 반시계방향으로 구동하게 되면, 제2전자클러치(18)를 통해 구동기어(21)로 동력이 전달되는 동시에 구동기어(21)도 모터(14)와 동일한 반시계방향으로 회전을 하게 된다.On the other hand, when the motor 14 is driven counterclockwise for steering, power is transmitted to the drive gear 21 through the second electromagnetic clutch 18 and at the same time the drive gear 21 is also connected to the motor 14. Rotate in the same counterclockwise direction.

이때, 상기 구동기어(21)에 동시에 맞물려 있는 제1 및 제2원웨이 베어링(22,23)중, 동력전달매개기어(24)와 동축으로 연결된 제1원웨이 베어링(22)은 시계방향으로 회전하면서 동력전달매개기어(24)에 동력을 전달하게 되고, 반면에 제2원웨이 베어링(23)은 공회전하면서 출력기어(25)에 대한 동력을 차단하는 역할을 한다.At this time, of the first and second one-way bearings 22 and 23 simultaneously engaged with the drive gear 21, the first one-way bearing 22 coaxially connected with the power transmission medium gear 24 is clockwise. While rotating, power is transmitted to the power transmission medium gear 24, while the second one-way bearing 23 serves to block power to the output gear 25 while idling.

따라서, 상기 동력전달매개기어(24)가 시계방향으로 회전하는 동시에 동력전달매개기어(24)와 맞물려 있는 출력기어(25)가 반시계방향으로 회전하면서 컴프레서(30)의 구동이 이루어지게 되어, 에어컨이 작동하게 된다.
Therefore, while the power transmission medium gear 24 rotates clockwise and the output gear 25 meshed with the power transmission medium gear 24 rotates counterclockwise, the compressor 30 is driven. The air conditioner will be activated.
