Description
본 발명은 자동차 엔진으로부터의 회전력을 변속기로 변속하여 휠을 구동시키기 위해 차동장치와 드라이브샤프트를 통해 동력을 전달하는 일련의 동력전달구조에서 상기 차동장치와 드라이브샤프트 사이의 연결구조에 관한 것이다.The present invention relates to a connection structure between the differential and the drive shaft in a series of power transmission structures for transmitting power through the differential and the drive shaft to drive the wheel by shifting the rotational force from the automobile engine to the transmission.
자동차는 엔진에서 발생된 동력을 바퀴에 적절히 전달하기 위해 클러치와 변속기 및 차동장치 등을 사용하고 있는 바, FR식 자동차는 차체의 전방에 위치한 변속기가 추진축을 통해 후륜의 드라이브샤프트가 장착되는 차동장치에 연결되고, 승용차에 많이 사용되는 FF식 자동차는 변속기와 차동장치가 일체로 된 트랜스액슬 상태에서 차동장치에 드라이브샤프트를 연결하는 구조이다.Automobiles use clutches, transmissions, and differentials to properly transfer the power generated by the engine to the wheels. In FR cars, the transmissions in front of the body are equipped with rear drive shafts through the propulsion shaft. The FF type car, which is connected to and used in passenger cars, is a structure in which a drive shaft is connected to a differential device in a transaxle state in which a transmission and a differential are integrated.
도 1에는 변속기와 차동장치가 일체로 연결된 트랜스액슬(100)에서 차동장치의 양측에 좌우의 드라이브샤프트(102)가 연결된 구조가 도시되어 있는 바, 엔진의 동력이 변속기를 통해 차량의 운전상태에 적합한 속도로 변속되면, 차동장치는 자동차의 선회 주행시 내륜과 외륜의 속도차를 발생시켜 차량의 원활한 방향전환이 가능하도록 하고 불규칙한 도로에서 양쪽바퀴의 회전수를 자동적으로 다르게 하여 차량의 원활한 주행이 가능하도록 한다.1 illustrates a structure in which drive shafts 102 on the left and right sides are connected to both sides of a differential device in a transaxle 100 in which a transmission and a differential device are integrally installed, and the power of the engine is changed to a driving state of the vehicle through the transmission. When shifted to a suitable speed, the differential system generates a speed difference between the inner and outer wheels during the turning of the car, allowing the vehicle to turn smoothly and automatically changing the rotation speed of both wheels on irregular roads, so that the vehicle can run smoothly. Do it.
여기서, 상기 트랜스액슬(100) 내의 차동장치 구조를 보면 도 2에 도시된 바와 같이 변속기의 출력축으로부터 동력을 전달받는 차동기어케이스(104)의 링기어(106)와, 상기 차동기어케이스(104)에 피니언샤프트(108)로 지지된 피니언기어(110)와, 상기 피니언기어(110)에 치합되며 드라이브샤프트(102)가 연결되는 양쪽의 두 사이드기어(112) 등으로 구성되어 있는 바, 상기 사이드기어(112)와 드라이브샤프트(102)의 연결구조는 드라이브샤프트(102)를 사이드기어(112)에 스플라인 결합하도록 되어 있고 그 연결부위에는 시일링(114)을 설치하여 이물질의 유입을 차단하도록 된 구조이다.Here, in the differential axle structure of the transaxle 100, as shown in FIG. 2, the ring gear 106 of the differential gear case 104 receives power from the output shaft of the transmission, and the differential gear case 104. The pinion gear 110 supported by the pinion shaft 108 and the two side gears 112, etc., which are engaged with the pinion gear 110 and are connected to the drive shaft 102, The connection structure of the gear 112 and the drive shaft 102 is to spline-couple the drive shaft 102 to the side gear 112 and to install a seal ring 114 at the connection portion to block the inflow of foreign substances. Structure.
그런데, 상기한 바와 같이 드라이브샤프트(102)가 사이드기어(112)에 스플라인 결합된 상태에서는 스플라인의 특성상 사이드기어(112)와 드라이브샤프트(102)의 사이에 유격이 발생될 소지가 많아서, 이것이 차량의 구동토크의 변화시에는 백래쉬(back lash)로 작용하여 이상충격이나 진동이 발생되어 실내로 전달되는 문제점이 있다.However, in the state where the drive shaft 102 is splined to the side gear 112 as described above, there is a possibility that a play is generated between the side gear 112 and the drive shaft 102 due to the characteristics of the spline, which is a vehicle. When the drive torque is changed, there is a problem that an abnormal shock or vibration is generated by acting as a backlash and transmitted to the room.
이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 차동장치에 드라이브샤프트가 조립되는 구조를 개선하여 차량의 구동토크 변동시에 백래쉬에 의한 충격이나 진동이 발생되지 않도록 한 자동차의 드라이브샤프트 연결구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the drive shaft is assembled in the differential device to improve the structure of the drive of the vehicle so that the impact or vibration caused by the backlash does not occur when the drive torque of the vehicle changes The purpose is to provide a shaft connection structure.

보다 상세히 살펴보면, 변속기케이스(5)에 베어링(7)을 통해 회전 가능하게 지지되며 변속기의 출력축에 치합되는 링기어(106)를 외주면에 마련한 차동기어케이스(104)와, 상기 차동기어케이스(104)의 내측에 상기 차동기어케이스(104)의 회전방향에 수직한 회전축을 제공하는 피니언샤프트(108)로 지지되는 피니언기어(110)와, 상기 피니언기어(110)의 회전축에 수직하는 방향의 회전축을 가지고 치합되는 사이드기어(1)를 일체로 형성한 드라이브샤프트(3)로 구성되어 있다.Looking in more detail, the differential gear case 104 and the differential gear case 104 which is rotatably supported on the transmission case 5 through the bearing 7 and is provided on the outer circumferential surface of the ring gear 106 engaged with the output shaft of the transmission. ) The pinion gear 110 supported by the pinion shaft 108 to provide a rotation axis perpendicular to the rotation direction of the differential gear case 104, and a rotation axis in a direction perpendicular to the rotation axis of the pinion gear 110. It consists of a drive shaft (3) in which the side gear (1) to be engaged with each other is integrally formed.
물론, 상기 드라이브샤프트(3)와 변속기케이스(5)의 연결부위에는 시일링(9)을 설치하여 먼지나 기타의 이물질이 침투하지 못하도록 한다.Of course, a seal ring 9 is installed at the connection portion between the drive shaft 3 and the transmission case 5 to prevent dust or other foreign matter from penetrating.
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.
