Description

4륜구동 차량의 후륜 동력전달장치{A REAR POWER TRAIN OF A 4-WHEEL DRIVE VEHICLE}Rear wheel drive of four-wheel drive vehicle {A REAR POWER TRAIN OF A 4-WHEEL DRIVE VEHICLE}

본 발명은 4륜구동차량의 후륜 동력전달장치에 관한 것으로서, 보다 상세하게는 후륜의 좌우륜을 각각 독립적으로 구동력 제어함과 아울러 보다 강한 토크의 전달이 이루어질 수 있도록 하는 것에 관한 것이다.The present invention relates to a rear wheel power transmission device of a four-wheel drive vehicle, and more particularly, to control the driving force independently of the left and right wheels of the rear wheel, and also to enable stronger torque transmission.

종래의 4륜구동 파워트레인 중 풀타임 타입은 비스코스커플링방식, 센터디퍼렌셜 방식 등 여러 방식이 있으며, 도 1에는 로터리블레이드커플링(rotary blade coupling) 방식이 도시되어 있다. The full-time type of the conventional four-wheel drive powertrain has a number of methods, such as a viscose coupling method, a center differential method, a rotary blade coupling (rotary blade coupling) method is shown in FIG.

즉, 엔진(100)의 동력을 변속기(102)에서 받아 전륜(104,104')에 전달하고, 동시에 추진축(106)을 구동하도록 되어 있으며, 상기 추진축(106)에는 로터리블레이드커플링(108)을 경유하여 후륜(110,110')의 디퍼렌셜(112)로 동력을 전달할 수 있도록 되어 있는 것이다.That is, the power of the engine 100 is received from the transmission 102 and transmitted to the front wheels 104 and 104 ', and simultaneously drives the propulsion shaft 106, and the propulsion shaft 106 is via the rotary blade coupling 108. It is to be able to transfer the power to the differential 112 of the rear wheels (110, 110 ').

상기한 바와 같은 4륜구동 파워트레인에서는 정상 주행시 상기 전륜(104,104')이 구동륜으로 작용하며, 전륜과 후륜의 속도차가 발생되지 않는 한 상기 로터리블레이드커플링(108)에서는 토크를 전달하지 않아 상기 후륜(110,110')은 종동륜으로서 작용하고, 험로의 주행이나 선회주행 등과 같이 전륜과 후륜의 회전속도에 차이가 발생되는 경우에는 상기 로터리블레이드커플링(108)에서 토크를 전달하여 후륜(110,110')도 구동륜의 역할을 하여 4륜구동이 이루어지게 된다.In the four-wheel drive powertrain as described above, the front wheels 104 and 104 'act as driving wheels during normal driving, and the rotary blade coupling 108 does not transmit torque unless the speed difference between the front and rear wheels is generated. 110, 110 ') acts as a driven wheel, and if a difference occurs in the rotational speed of the front and rear wheels such as driving on a bad road or turning, the rear blades 110, 110' are also transmitted by transmitting torque from the rotary blade coupling 108. Four-wheel drive is achieved by acting as a driving wheel.

여기서, 상기 로터리블레이드커플링(108)의 작용을 도 2를 통해 살펴보면, 그 구조가 변속기(102)측에 연결되는 하우징(108-1)의 내측에는 다수의 아웃터플레이트(108-2)가 일체로 연결되어 있고, 상기 아웃터플레이트(108-2)의 사이에는 후륜측에 연결된 로터(108-3)에 고정된 다수의 인너플레이트(108-4)가 설치되며, 상기 하우징(108-1)의 일측에는 피스톤(108-5)이 설치되어 로터(108-3)에 연결되어 회전되는 팬 형상의 블레이드(108-6)가 봉입되어 있는 실리콘오일(108-7)의 유체 전단력을 이용해 상기 아웃터플레이트(108-2)와 인너플레이트(108-4)가 구성하는 다판클러치(108-8)를 밀도록 되어 있어서, 상기 로터(108-3)와 하우징(108-1) 사이에 회전속도차가 발생하는 경우에만 상기 피스톤(108-5)이 다판클러치(108-8)를 작동시켜 토크의 전달이 이루어지도록 한다.Here, looking at the operation of the rotary blade coupling 108 through Figure 2, a plurality of outer plate 108-2 is integrated inside the housing 108-1, the structure of which is connected to the transmission 102 side. Connected to the outer plate 108-2, a plurality of inner plates 108-4 fixed to the rotor 108-3 connected to the rear wheel side are installed between the outer plate 108-2, and the housing 108-1 One side of the outer plate using the fluid shear force of the silicon oil (108-7) in which the piston (108-5) is installed and the fan-shaped blade (108-6) is connected to the rotor (108-3) is rotated It is to push the multi-plate clutch (108-8) constituted by the (108-2) and the inner plate (108-4), the rotation speed difference between the rotor (108-3) and the housing (108-1) Only in this case the piston 108-5 actuates the multi-plate clutch 108-8 so that torque is transmitted.

그런데, 상기한 바와 같이 구성되어 작동되는 4륜구동 파워트레인은 상기한 바와 같이 하우징(108-1)의 일측에서 회전되는 블레이드(108-6)가 발생시키는 유체 전단력에 의한 압력에만 의존하여 상기 다판클러치(108-8)를 통해 토크를 전달하게 되므로 심한 험로의 탈출 등 높은 토크의 전달이 필요한 경우에는 그 한계가 있다.However, the four-wheel drive powertrain configured and operated as described above depends on only the pressure due to the fluid shear force generated by the blade 108-6 rotated on one side of the housing 108-1 as described above. Since the torque is transmitted through (108-8), there is a limit in the case where a high torque transmission is required, such as escaping a severe bad road.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 험로의 탈출 등과 같이 높은 토크를 요구하는 상황 속에서, 충분한 구동토크를 전달할 수 있으며, 후륜의 좌우륜에 전달되는 구동력을 독립적으로 제어하여 공급할 수 있도록 함에 의해 보다 향상된 구동력 및 차량 안정성을 확보할 수 있도록 한 4륜구동 차량의 후륜 동력전달장치를 제공함에 그 목적이 있다. Accordingly, the present invention has been made in order to solve the above problems, in a situation that requires a high torque, such as escape of a bad road, it is possible to deliver a sufficient driving torque, independently of the driving force transmitted to the left and right wheels of the rear wheels It is an object of the present invention to provide a rear wheel power transmission device of a four-wheel drive vehicle that can ensure a more improved driving force and vehicle stability by providing a controlled supply.

상기한 바와 같은 목적을 달성하기 위한 본 발명 4륜구동 차량의 후륜 동력전달장치는 추진축으로부터 동력을 전달받는 후륜구동기어와; 상기 후륜구동기어에 일체로 연결되며, 휠측과 후륜구동기어측의 회전속도차에 따라서 토크의 전달율이 변화하도록 구성되어, 후륜의 양측에 각각 설치된 클러치수단으로 구성된 것을 특징으로 한다.Rear wheel drive of the present invention four-wheel drive vehicle for achieving the above object is a rear wheel drive gear for receiving power from the propulsion shaft; It is integrally connected to the rear wheel drive gear, and configured to change the transmission rate of the torque in accordance with the rotational speed difference between the wheel side and the rear wheel drive gear side, characterized in that composed of clutch means provided respectively on both sides of the rear wheel.

이하, 본 발명의 실시예를 첨부된 도면을 참조하여 설명하면 다음과 같다. 아울러, 종래 기술의 설명에 사용되었던 부품과 동일한 부품의 명칭 및 기호는 동일한 것을 사용하여 설명하기로 한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the names and symbols of the same parts as those used in the description of the prior art will be described using the same.

도 3에는 본 발명에 의한 4륜구동 차량의 후륜 동력전달장치가 도시된 바, 3 shows a rear wheel power transmission device of a four-wheel drive vehicle according to the present invention;

엔진(100)과 변속기(102)를 통해 전륜(104,104')에는 상시 구동력이 전달되고 있는 구조이며, 추진축(106)을 통해 후륜(110,110')측으로 동력이 전달되도록 되어 있어서, 상기 추진축(106)으로부터 동력을 전달받는 후륜구동기어(1)와, 상기 후륜구동기어(1)에 일체로 연결되며 휠측과 후륜구동기어측의 회전 속도차에 따라서 토크의 전달율이 변화하도록 구성되어 후륜의 양측에 각각 설치된 클러치수단(3)으로 구성되어 있다.The driving force is constantly transmitted to the front wheels 104 and 104 'through the engine 100 and the transmission 102, and power is transmitted to the rear wheels 110 and 110' through the propulsion shaft 106, so that the propulsion shaft 106 is provided. It is connected to the rear wheel drive gear (1) and the rear wheel drive gear (1) which receives power from the vehicle, and the transmission ratio of torque is changed according to the rotation speed difference between the wheel side and the rear wheel drive gear side, respectively, on both sides of the rear wheel. It consists of the clutch means 3 provided.

여기서, 상기 클러치수단(3)은 상세히 도시된 바와 같이 후륜구동기어(1)에 직결된 하우징(5)과, 상기 하우징(5)의 내측에 형성된 로터리블레이드커플링(7)과, 상기 로터리블레이드커플링(7)의 블레이드(7-1)와 하우징(5) 사이에 마련된 공간에 구성된 험프발생수단(9)으로 구성되었는데,Here, the clutch means (3) is a housing (5) directly connected to the rear wheel drive gear (1), a rotary blade coupling (7) formed inside the housing (5), and the rotary blade as shown in detail It consists of a hump generating means (9) configured in a space provided between the blade (7-1) of the coupling (7) and the housing (5),

상기 험프발생수단(9)은 상기 하우징(5)의 내측에 일체로 연결된 다수의 험프용 아웃터플레이트(9-1)와, 상기 로터리블레이드커플링의 로터(7-2)에 일체로 연결되어 상기 험프용 아웃터플레이트(9-1)의 사이에 각각 위치하는 다수의 험프용 인너플레이트(9-2)와, 상기 다수의 험프용 아웃터플레이트(9-1)와 인너플레이트(9-2)의 사이에 충진된 비스커스커플링용 실리콘오일(9-3)로 이루어져 있다.The hump generating means (9) is integrally connected to the plurality of hump outer plate (9-1) and the rotor (7-2) of the rotary blade coupling is integrally connected to the inside of the housing (5) Between a plurality of hump inner plates 9-2 respectively positioned between the hump outer plates 9-1, and the plurality of hump outer plates 9-1 and the inner plates 9-2. It consists of a silicon oil (9-3) for the biscus coupling filled in.

즉, 상기 클러치수단(3)은 종래의 로터리블레이드커플링과 비스커스커플링이 일체로 결합된 구조를 가지고 있는 것이다.That is, the clutch means (3) has a structure in which the conventional rotary blade coupling and the viscous coupling are integrally coupled.

상기한 바와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

차량이 정상적인 주행 상태에 있는 경우에는 차량은 전륜(104,104')에서 발생되는 구동력에 의해 진행하면서, 상기 추진축(106)에 의한 후륜구동기어(1)의 회전속도와 두 후륜(110,110')의 회전속도가 동일하여 상기 클러치수단(3)에서는 토크가 전달되지 않으므로 두 후륜(110,110')은 종동륜으로 작용하게 된다.When the vehicle is in a normal driving state, the vehicle proceeds with the driving force generated from the front wheels 104 and 104 ', and the rotation speed of the rear wheel drive gear 1 and the rotation of the two rear wheels 110 and 110' by the propulsion shaft 106 are performed. Since the torque is not transmitted from the clutch means 3 because the speed is the same, the two rear wheels 110 and 110 ′ act as driven wheels.

상기한 바와 같은 주행상태에서 선회주행으로 접어들면, 상기 후륜(110,110')은 좌우륜이 각각 다른 회전속도를 갖게 되며, 이는 후륜구동기어(1)의 회전속도와도 각각 달라져서 상기 후륜구동기어(1)에 일체로 연결된 하우징(5)과 후륜(110,110')에 일체로 연결된 로터(7-2)는 서로 상대적인 회전이 발생하면서 선회주행에 따라 필요한 내륜측과 외륜측의 회전 속도차를 제공하게 되며, 이러한 운전 영역은 상기 클러치수단의 로터리블레이드커플링(7)과 험프발생수단(9)에서 하우징(5)측과 로터(7-2)측이 서로 허용하는 일정수준의 미끄러짐에 의해 가능하게 된다.When the vehicle enters the turning drive in the driving state as described above, the rear wheels 110 and 110 ′ have left and right wheels having different rotational speeds, which are also different from the rotational speeds of the rear wheel drive gears 1 and the rear wheel drive gears ( 1) the housing 5 connected integrally to the rotor 5 and the rotor 7-2 integrally connected to the rear wheels 110 and 110 'provide relative rotational speed differences between the inner and outer ring sides as required by turning. This driving region is made possible by a certain level of sliding allowed by the housing 5 side and the rotor 7-2 side of the rotary blade coupling 7 and the hump generating means 9 of the clutch means. do.

필요한 경우에는 수렁에 빠진 휠의 회전속도와 빠지지 않은 휠의 회전속도 및 상기 후륜구동기어(1)의 회전속도 차이가 커져서 상기 로터리블레이드커플링(7)이 작동되면서 수렁에 빠진 휠의 회전토크의 일부를 상기 하우징(5) 및 후륜구동기어(1)측을 통해 빠지지 않은 휠에 전달하는 차동제한기능을 수행하게 된다.If necessary, the difference between the rotational speed of the bog wheel, the rotational speed of the rim wheel, and the rotational speed of the rear wheel drive gear 1 increases, so that the rotary blade coupling 7 is operated to Part of the housing 5 and the rear wheel drive gear (1) to perform a differential limiting function for transmitting to the wheel does not fall out.

즉, 블레이드(7-1)의 회전에 의해 발생된 실리콘오일의 유체 전단력에 의해 상기 로터리블레이드커플링의 피스톤(7-3)이 로터리블레이드커플링의 다판클러치(7-4)를 작동시킴에 의해 토크의 전달이 이루어져 수렁에서 빠져나올 수 있는 토크가 수렁에 빠지지 않은 쪽의 휠에 전달될 수 있게 되는 것이다.That is, the piston 7-3 of the rotary blade coupling actuates the multi-plate clutch 7-4 of the rotary blade coupling by the fluid shear force of the silicon oil generated by the rotation of the blade 7-1. By this, the torque is transmitted so that the torque that can be released from the bog can be transmitted to the wheel on the side that is not in the bog.

나아가, 차량이 심한 험로를 주행하는 경우에는 상기한 바와 같은 두 후륜(110,110')과 후륜구동기어(1)가 각각 그 회전 속도차가 매우 크게 형성되는 바, 이와 같은 경우에는 상기와 같이 발생되는 큰 회전 속도차에 의해 상기 험프(hump)발생수단(9)이 작용하여 강한 토크의 전달이 이루어질 수 있도록 한다.In addition, when the vehicle is traveling in a rough road, the two rear wheels 110 and 110 ′ and the rear wheel drive gear 1 as described above are respectively formed with a very large rotation speed difference. The hump generating means 9 is acted upon by the rotational speed difference so that a strong torque can be transmitted.

즉, 상기 험프발생수단(9)은 로터(7-2)측의 험프용 인너플레이트(9-1)와 하우징(5)측의 험프용 아웃터프레이트(9-2)가 큰 회전 속도차를 가짐에 따라 이들 사이의 공간에 충진된 실리콘오일(9-3)에 발생되는 강한 유체 전단력이 실리콘오일의 온도를 상승시키고, 그에 따라 상기 공간의 압력이 급격히 상승됨에 의해 상기 험프용 인너플레이트(9-1)가 그 전후에 발생된 압력차에 의해 상기 험프용 아웃터플레이트(9-2)에 직결상태가 되는 험프(hump)현상을 일으켜 전달토크가 급격히 상승하게 되는 것이다.That is, the hump generating means 9 has a large rotation speed difference between the hump inner plate 9-1 on the rotor 7-2 side and the hump outer plate 9-2 on the housing 5 side. As a result, a strong fluid shear force generated in the silicon oil 9-3 filled in the space therebetween increases the temperature of the silicon oil, and accordingly the pressure of the space is rapidly increased, thereby causing the hump inner plate 9-. Due to the pressure difference generated before and after 1), a hump phenomenon that is directly connected to the hump outer plate 9-2 is caused, and the transmission torque is rapidly increased.

따라서, 종래에 로터리블레이드커플링만으로는 전달하기 어려운 높은 수준의 토크전달이 가능해짐에 의해 극심한 험로 탈출 등의 경우에 높은 구동성능과 안정성을 확보할 수 있게 됨은 물론, 상기한 바와 같이 두 후륜에 각각 토크를 조절하여 전달할 수 있게 됨에 의해 독립적인 구동력 제어로 향상된 구동력 및 차량안정성을 얻을 수 있다.Therefore, it is possible to secure high driving performance and stability in the case of extreme hurricane escape due to the high torque transmission that is difficult to transmit by the rotary blade coupling conventionally, as well as to each of the two rear wheels as described above. Since the torque can be adjusted and transmitted, independent driving force control can provide improved driving force and vehicle stability.

이상 설명한 바와 같이 본 발명에 의하면, 험로의 탈출 등과 같이 높은 토크를 요구하는 상황 속에서, 충분한 구동토크를 전달할 수 있으며, 후륜의 좌우륜에 전달되는 구동력을 독립적으로 제어하여 공급할 수 있도록 함에 의해 보다 향상된 구동력 및 차량 안정성을 확보할 수 있도록 한다. As described above, according to the present invention, sufficient driving torque can be transmitted in a situation requiring high torque, such as escape of a bad road, and by allowing the driving force transmitted to the left and right wheels of the rear wheel to be independently controlled and supplied. Improved driving force and vehicle stability are ensured.
