Description

토크 벡터링 장치{Device for torque vectoring}Torque vectoring device {Device for torque vectoring}

본 발명은 토크 벡터링 장치에 관한 것으로서, 보다 상세하게는 1모터 e-AWD(All Wheel Drive) 등의 고성능 환경차에 적용되어 선회 성능을 향상시키는 토크 벡터링 장치에 관한 것이다.The present invention relates to a torque vectoring device, and more particularly, to a torque vectoring device applied to a high-performance environment vehicle such as a one-motor e-AWD (All Wheel Drive) to improve turning performance.

일반적으로 토크 벡터링 장치는 차량의 민첩한 운동성능 및 핸들링 성능을 향상시기 위하여 좌우측 바퀴에 전달되는 토크의 크기를 독립적이면서 자유롭게 조절하기 위한 장치이다.In general, a torque vectoring device is a device for independently and freely adjusting the magnitude of torque transmitted to left and right wheels in order to improve agile movement performance and handling performance of a vehicle.

여기서, 토크 벡터링(torque vectoring)이라 함은 자동차에서 바퀴로 전달되는 엔진의 출력 또는 구동력에 대하여 크기와 방향 모두를 표현하기 위한 것으로, 바퀴에 전달되는 토크의 크기와 방향, 그 중에서도 같은 차축선상의 양측 바퀴로 각각 전달되는 토크에 변화를 주기 위한 기술을 의미한다.Here, the torque vectoring is to express both the magnitude and direction of the engine output or driving force transmitted from the vehicle to the wheels, and the magnitude and direction of the torque transmitted to the wheels, especially on the same axle line. It refers to a technology to change the torque transmitted to each wheel on both sides.

즉, 토크 벡터링은 양측 바퀴로 전달되는 토크의 크기와 방향을 달리하는 것으로, 바퀴에 걸리는 부하에 따라 좌우측 바퀴로 배분되는 토크 비율이 달라지는 디퍼렌셜에 부가적인 기능으로 적용된다.That is, torque vectoring varies the magnitude and direction of the torque transmitted to both wheels, and is applied as an additional function to the differential in which the torque ratio distributed to the left and right wheels varies according to the load applied to the wheels.

이러한 기능을 위한 토크 벡터링 장치는 운전자의 주행의도가 반영되도록 하여 능동적으로 디퍼렌셜의 기능을 제어함으로써 좌우 바퀴로 배분되는 토크의 비율을 조절하게 된다. The torque vectoring device for this function adjusts the ratio of the torque distributed to the left and right wheels by actively controlling the function of the differential by reflecting the driving intention of the driver.

이에 따라, 운전자는 구동력을 더 적극적으로 활용할 수 있고 핸들링 특성의 향상도 기대할 수 있다.Accordingly, the driver can more actively utilize the driving force and can expect improvement in handling characteristics.

그러나 토크 벡터링 장치는 디퍼렌셜의 기본적인 기능은 그대로 유지하면서, 필요한 상황에 따라 적절한 수준의 토크를 필요한 바퀴로 필요한 만큼 전달하는 기능이 더해져야 하기 때문에 기술적으로 구현하는 것은 쉽지 않다.However, it is not easy to implement the torque vectoring device technically because the function of transmitting an appropriate level of torque to the necessary wheels according to the necessary situation while maintaining the basic function of the differential must be added.

최근, 토크 벡터링 장치는 내연기관을 사용하는 구동계보다 모터의 배치와 제어에 따라 토크 벡터링을 휠씬 정확하게 구현할 수 있는 전기자동차 기술이 발전하면서 연구개발이 활발하게 진행되고 있다. 특히, 환경차의 고성능화가 진행되면서, 전기자동차(EV) 등의 AWD(All Wheel Drive)의 후방 디퍼렌셜에 적용되어 고성능 환경차의 선회 성능 향상을 위한 요소 기술로의 연구개발이 활발하다.Recently, research and development of a torque vectoring device has been actively conducted as an electric vehicle technology capable of implementing torque vectoring more accurately according to the arrangement and control of a motor than a drive system using an internal combustion engine has developed. In particular, as the high performance of environmental vehicles progresses, research and development of elemental technologies for improving the turning performance of high-performance environmental vehicles by being applied to the rear differential of AWD (All Wheel Drive) such as electric vehicles (EVs) is active.

이러한 환경차의 경우, 일반 내연기관 자동차와 다르게 트랜스퍼 샤프트와 같은 기계요소가 필요 없고, 2모터 e-AWD(All Wheel Drive) 및 전기자동차(EV)의 경우, 모터 제어 기술의 적용만으로 토크 벡터링의 구현이 가능하나, 1모터 e-AWD(All Wheel Drive)의 경우, 최적화된 후륜 동력 분배에 의한 선회 성능 향상의 실현을 위한 다양한 토크 벡터링 기술 개발이 요구된다. In the case of these environmental vehicles, unlike general internal combustion engine vehicles, mechanical elements such as transfer shafts are not required. Although it is possible to implement, in the case of one-motor e-AWD (All Wheel Drive), development of various torque vectoring technologies is required to realize improved turning performance by optimized rear wheel power distribution.

이 배경기술 부분에 기재된 사항은 발명의 배경에 대한 이해를 증진하기 위하여 작성된 것으로서, 이 기술이 속하는 분야에서 통상의 지식을 가진 자에게 이미 알려진 종래 기술이 아닌 사항을 포함할 수 있다.Matters described in this background section are prepared to enhance understanding of the background of the invention, and may include matters that are not already known to those of ordinary skill in the art to which this technology belongs.

상기 세로선과 가로선의 설정은 유성기어트레인의 당업자라면 당연히 알 수 있는 공지의 내용이므로 상세한 설명은 생략한다.Since the setting of the vertical line and the horizontal line is well known to those skilled in the planetary gear train, a detailed description thereof will be omitted.

이러한 토크 벡터링 장치의 운전조건에 따른 토크 벡터링 작동을 도 2의 레버선도를 통해 살펴보면 다음과 같다.The torque vectoring operation according to the operating conditions of the torque vectoring device is as follows through the lever diagram of FIG. 2 .

먼저, 도 2를 참조하면, 제1 회전요소(N1)는 제2 클러치(CL2)를 통하여 제7 회전요소(N7)와 선택적으로 연결되고, 제2 회전요소(N2)는 제5 회전요소(N5)와 고정 연결된 상태로 제1 클러치(CL1)를 통하여 제7 회전요소(N7)와 선택적으로 연결되며, 제3 회전요소(N3)는 제4 회전요소(N4)와 제8 회전요소(N8)와 고정 연결된다.

[우선회 주행] [Priority driving]

도 2의 (C)를 참조하면, 우선회 주행은 제1 클러치(CL1)가 작동 상태로 이루어진다.Referring to FIG. 2C , the priority driving is performed in an operating state of the first clutch CL1.

이에 따라, 제1 클러치(CL1)의 작동으로 제2 회전요소(N2)가 제7 회전요소(N7)와 동력 연결되고, 모터/제너레이터(MG)로부터 감속기구(10)를 통하여 차동기구(20)인 제3 유성기어세트(PG3)의 제9 회전요소(N9)로 감속되어 입력되는 회전동력은 제7 회전요소(N7)에 비하여 제8 회전요소(N8)에 더 큰 회전수와 토크로 작용하여 좌우측 출력축(OS1)(OS2)으로 출력된다. Accordingly, the second rotational element N2 is power-connected to the seventh rotational element N7 by the operation of the first clutch CL1 , and the differential mechanism 20 from the motor/generator MG through the reduction mechanism 10 . ), the rotational power inputted after being decelerated to the ninth rotational element N9 of the third planetary gear set PG3 is a larger rotational speed and torque to the eighth rotational element N8 than the seventh rotational element N7. It acts and is output to the left and right output shafts OS1 (OS2).

이때, 토크는 선회 외측인 좌측 바퀴로 회전동력을 전달하는 좌측 출력축(OS1)이 우측 출력축(OS2)에 비하여 더 크게 배분되어 우선회 주행을 가능하게 한다.At this time, the torque is distributed larger than that of the left output shaft OS1, which transmits rotational power to the left wheel outside the turning, compared to the right output shaft OS2, so that right-handed driving is possible.

상기와 같이, 본 발명의 실시 예에 따른 토크 벡터링 장치는 1모터 e-AWD(All Wheel Drive)와 같은 고성능 환경차에 적용되어 선회 주행 등의 운전조건에 따른 토크 벡터링을 통해 차량의 선회 주행 성능 등의 운정성을 향상시킬 수 있다.As described above, the torque vectoring device according to an embodiment of the present invention is applied to a high-performance environment vehicle such as a one-motor e-AWD (All Wheel Drive), and the turning driving performance of the vehicle through torque vectoring according to driving conditions such as turning driving. etc. can be improved.

또한, 토크 벡터링 기구(30)에 적용되는 2개의 클러치(CL1)(CL2)를 적용하여 직진주행 또는 토크 벡터링 제어가 불필요한 경우에는 작동하지 않도록 하여 작동유압의 손실을 최소화할 수 있고, 선회주행 등의 토크 벡터링 기능이 필요한 경우에만 슬립 및 체결하는 것으로, 제어 및 효율 측면에서도 유리한 이점이 있다. In addition, by applying the two clutches CL1 and CL2 applied to the torque vectoring mechanism 30, it is possible to minimize the loss of hydraulic pressure by not operating when straight travel or torque vectoring control is unnecessary. It slips and engages only when the torque vectoring function is required, which is advantageous in terms of control and efficiency.
