Description
본 발명은 자동차의 차동 장치의 구조에 관한 것이다.The present invention relates to the structure of a differential device of a motor vehicle.
종래의 자동차용 차동 장치는 도1에 도시된 바와 같이, 내측의 양측 사이드 기어(5)에 드라이브 샤프트(3)가 연결되어 바퀴에 동력을 전달하는 구조로 되어 있다. As shown in FIG. 1, the conventional vehicle differential apparatus has a structure in which drive shafts 3 are connected to both side side gears 5 on the inner side to transmit power to wheels.
즉, 차동 장치의 케이스(1)의 외측에는 차동장치 구동 기어(2)가 볼트(7)에 의해 체결되어지고, 내측에는 사이드 기어(5), 피니언 기어(6) 및 피니언 기어 샤프트가 조립되어 있어서, 차동장치 구동 기어(2)로부터 엔진에서 전달된 구동력이 피니언 기어 샤프트(8)를 통해 피니언 기어(6)에 전달되어 지고, 피니언 기어(6)에 물려 있는 사이드 기어(5)를 통하여 최종적으로 드라이브 샤프트(3)에 동력이 전달되어지게 된다. That is, the differential drive gear 2 is fastened by a bolt 7 on the outside of the case 1 of the differential device, and the side gear 5, the pinion gear 6 and the pinion gear shaft are assembled inside. In this case, the driving force transmitted from the engine from the differential drive gear 2 is transmitted to the pinion gear 6 via the pinion gear shaft 8 and finally through the side gear 5 which is bitten by the pinion gear 6. As a result, power is transmitted to the drive shaft 3.
그런데, 차동장치 케이스(1)에 설치된 피니언 기어(6)의 회전축인 피니언 기어 샤프트(8)는 차동장치 케이스(1)에 가공된 구멍 부위에 삽입되어져 있는데, 이 피니언 기어 샤프트(8)를 고정하기 위하여, 차동장치 케이스(1) 및 피니언 기어 샤프트(8)에 각각 구멍이 가공되어지고 여기에 핀(9)이 압입되어지는 구조로 되어 있다. By the way, the pinion gear shaft 8, which is the rotation shaft of the pinion gear 6 installed in the differential case 1, is inserted into the hole portion machined in the differential case 1, and the pinion gear shaft 8 is fixed. In order to achieve this, a hole is formed in each of the differential case 1 and the pinion gear shaft 8 and the pin 9 is press-fitted therein.
본 발명은 간단한 구조의 차동 장치에 관한 것으로서, 종래의 자동차용 차동 장치에 비하여 원가를 절감할 수 있는 단순한 구조의 차동 장치를 제공한다.The present invention relates to a differential structure of a simple structure, to provide a differential structure of a simple structure that can reduce the cost compared to the conventional automotive differential device.
상기한 목적을 실현하기 위하여 본 발명에서는, 도2에 도시된 바와 같이 차동장치 구동 기어(2a)와 차동장치 케이스(1a)를 고정하는 볼트(7a)를 연장하고, 피니언 기어 샤프트(8a)에 나사 구멍을 가공한 다음, 여기에 볼트(7a)가 체결되어지도록 하였다.In order to achieve the above object, in the present invention, as shown in Fig. 2, the bolt 7a for securing the differential drive gear 2a and the differential case 1a is extended, and the pinion gear shaft 8a is extended. After the screw holes were processed, bolts 7a were fastened thereto.
즉, 종래의 차동 장치 케이스(1)에 있는 핀(9) 조립용 구멍을 삭제하고, 피니언 기어 샤프트(8a)에 있던 종래의 핀 구멍 대신 암나사를 가공한 다음, 여기에 볼트(7a)가 체결되어지도록 하였다. That is, the hole for assembling the pin 9 in the conventional differential device case 1 is removed, and the female screw is machined instead of the conventional pin hole in the pinion gear shaft 8a, and then the bolt 7a is fastened thereto. To be done.
본 발명에서는 종래의 피니언 기어 샤프트 고정용 핀(9)이 삭제됨에 따라, 부품수 감소에 따른 조립 공수 감소 및 원가 절감이 가능하게 된다. In the present invention, as the pinion gear shaft fixing pin 9 of the related art is deleted, the number of assembly operations and the cost can be reduced by reducing the number of parts.
또한, 종래의 차동장치 케이스(1)에 가공되던 피니언 기어 샤프트 고정용 핀(9) 장착 구멍이 필요 없게 되므로 가공 공수가 감소하게 된다. In addition, since the mounting hole of the pinion gear shaft fixing pin 9, which has been processed in the conventional differential case 1, is unnecessary, the number of machining operations is reduced.
한편, 엔진으로부터 전달된 구동력이 차동장치 구동기어(2a)에서 볼트(7a)를 통하여 직접 피니언 기어 샤프트(8a)에 전달되어지므로, 차동장치 케이스(1a)에 직접적으로 작용하는 하중이 감소하게 되므로 차동장치 케이스(1a)의 경량화도 가능하게 된다. On the other hand, since the driving force transmitted from the engine is transmitted from the differential drive gear 2a directly to the pinion gear shaft 8a through the bolt 7a, the load acting directly on the differential case 1a is reduced. It is also possible to reduce the weight of the differential case 1a.
