한편, 상기 프로펠러 샤프트(10)로부터의 회전동력이 암스플라인(44) 및 숫스플라인(24) 간의 스플라인 결합부를 통해 피니언 샤프트(22)로 전달되어 피니언 샤프트(22)가 회전을 하게 되는데, 이 피니언 샤프트(22)의 전후 길이 등을 고려하여 디퍼런셜(20)의 내부에 장착된 디퍼런셜 베어링(26)이 피니언 샤프트(22)의 후단부를 회전 가능하게 지지하게 된다.Meanwhile, the rotational power from the propeller shaft 10 is transmitted to the pinion shaft 22 through the spline coupling between the female spline 44 and the male spline 24, causing the pinion shaft 22 to rotate. In consideration of the front-to-back length of the shaft 22, etc., the differential bearing 26 mounted inside the differential 20 rotatably supports the rear end of the pinion shaft 22.
이때, 상기 디퍼런셜 베어링(26)이 제위치를 벗어나면, 즉 상기 디퍼런셜 베어링(26)이 디퍼런셜(20) 내에서 축방향을 따라 바깥쪽으로 미세하게 위치 이동하면, 피니언 샤프트(22)에 대한 회전 지지력이 변경될 수 있으므로, 상기 디퍼런셜 베어링(26)이 디퍼런셜(20) 내의 제위치에 고정된 상태로 유지되어야만 피니언 샤프트(22)의 외경에 밀착되어 회전을 지지하는 역할을 일정하게 수행할 수 있다.At this time, if the differential bearing 26 is out of position, that is, if the differential bearing 26 is slightly moved outward along the axial direction within the differential 20, the rotational support force for the pinion shaft 22 Since this can be changed, the differential bearing 26 must remain fixed in place within the differential 20 to be in close contact with the outer diameter of the pinion shaft 22 and constantly perform its role of supporting rotation.
이를 위해, 상기 피니언 샤프트(22)의 후단쪽 외경부에는 디퍼런셜(20) 내부에 장착된 디퍼런셜 베어링(26)을 축방향을 따라 디퍼런셜(20)의 내측방향을 향하여 가압하는 프리로더(50, Preloader)가 삽입 장착된다.For this purpose, a preloader 50 is installed on the outer diameter portion of the rear end of the pinion shaft 22, which presses the differential bearing 26 mounted inside the differential 20 along the axial direction toward the inside of the differential 20. ) is inserted and installed.
좀 더 상세하게는, 상기 프리로더(50)는 원통형 형상으로서 그 내경부에 암나사산(52)이 형성고, 상기 피니언 샤프트(22)의 외경부에는 숫나사산(27)이 가공되어, 암나사산(52)과 숫나사산(27) 간의 나사 결합에 의하여 프리로더(50)가 피니언 샤프트(22)의 외경부에 축방향 이동 가능하게 체결되는 상태가 된다.More specifically, the preloader 50 has a cylindrical shape and has a female thread 52 formed on its inner diameter, and a male thread 27 is machined on the outer diameter of the pinion shaft 22, making it a female thread. The preloader 50 is fastened to the outer diameter portion of the pinion shaft 22 so as to be axially movable by screw engagement between (52) and the male thread (27).
이에, 상기 프리로더(50)를 조여주는 방향으로 나사 회전시키면, 프리로더(50)의 후단부가 디퍼런셜 베어링(26)을 움직이지 않게 가압하게 됨으로서, 상기 디퍼런셜 베어링(26)이 디퍼런셜(20) 내의 제위치에 고정된 상태로 유지되면서 피니언 샤프트(22)를 일정하게 회전 지지하게 된다.Accordingly, when the preloader 50 is screwed and rotated in the tightening direction, the rear end of the preloader 50 presses the differential bearing 26 so that it does not move, so that the differential bearing 26 is inside the differential 20. While remaining fixed in place, the pinion shaft 22 is supported for constant rotation.
본 발명에 따르면, 상기 프로펠러 샤프트(10)로부터 디퍼런셜(20)의 피니언 샤프트(22)로의 동력 전달이 안정적으로 이루어질 수 있도록 프로펠러 샤프트(10)와 디퍼런셜(20)의 피니언 샤프트(22) 간의 스플라인 결합 상태를 견고하게 유지시키는 동시에 동력 전달 작동시 피니언 샤프트(22) 등의 축방향 움직임을 구속시키는 것이 바람직하다.According to the present invention, the spline coupling between the propeller shaft 10 and the pinion shaft 22 of the differential 20 so that power can be stably transmitted from the propeller shaft 10 to the pinion shaft 22 of the differential 20.

(45) is formed, and a restrictor (60) that restricts the axial movement of the pinion shaft 22 is inserted and fastened into the first locking groove (25) and the second locking groove (45).
상기 리스트릭터(60)는 고탄성 플레이트를 이용하여 링 형상으로 제작된 것으로서, 내측의 제1구속단(61)과 외측의 제2구속단(62)이 반복적으로 교차 배열을 이루면서 원주방향을 따라 일체로 이어진 구조로 구비된다.The restrictor 60 is manufactured in a ring shape using a highly elastic plate, and the inner first restraining end 61 and the outer second restraining end 62 are repeatedly arranged in an alternating manner and are integrated along the circumferential direction. It is provided in a structure connected to .
특히, 상기 리스트릭터(60)는 마치 쐐기와 같은 스토퍼 역할을 할 수 있도록 내측의 제1구속단(61)에서 외측의 제2구속단(62)을 향하여 상향 경사지게 형성된 구조로 구비된다.In particular, the restrictor 60 is provided with a structure inclined upward from the inner first restraining end 61 toward the outer second restraining end 62 so that it can function as a stopper like a wedge.
이에, 상기 리스트릭터(60)의 제1구속단(61)이 피니언 샤프트(22)의 제1락킹홈(25)에 삽입되도록 하고, 제2구속단(62)이 등속조인트(40)의 커넥터(42)의 제2락킹홈(45)에 삽입되도록 함으로써, 도 5에서 잘 볼 수 있듯이 상기 리스트릭터(60)가 제1구속단(61)으로부터 제2구속단(62)을 향하여 상향 경사진 상태이므로 피니언 샤프트(22)의 축방향 움직임을 구속하는 쐐기 역할을 하게 된다.Accordingly, the first restraining end 61 of the restrictor 60 is inserted into the first locking groove 25 of the pinion shaft 22, and the second restraining end 62 is inserted into the connector of the constant velocity joint 40. By being inserted into the second locking groove 45 of (42), the restrictor 60 is inclined upward from the first restraint end 61 toward the second restraint end 62, as can be clearly seen in FIG. Therefore, it serves as a wedge to restrain the axial movement of the pinion shaft 22.
따라서, 상기 리스트릭터(60)에 의하여 피니언 샤프트(22)의 축방향 움직임을 구속되는 상태에서 프로펠러 샤프트(10)로부터 디퍼런셜(20)의 피니언 샤프트(22)로의 동력 전달이 안정적으로 이루어질 수 있다.Therefore, power can be stably transmitted from the propeller shaft 10 to the pinion shaft 22 of the differential 20 while the axial movement of the pinion shaft 22 is restricted by the restrictor 60.
한편, 본 발명에 따르면 상기와 같이 프로펠러 샤프트(10)와 디퍼런셜(20)의 피니언 샤프트(22) 간의 결합이 이루어진 후, 정비 작업 등을 위하여 프로펠러 샤프트(10)와 디퍼런셜(20)의 피니언 샤프트(22) 간을 용이하게 분리시킬 수 있다.Meanwhile, according to the present invention, after the coupling between the propeller shaft 10 and the pinion shaft 22 of the differential 20 is achieved as described above, the pinion shaft (22) of the propeller shaft 10 and the differential 20 is connected for maintenance work, etc. 22) The liver can be easily separated.
이를 위해, 상기 커넥터(42)의 입구쪽 내경과 상기 피니언 샤프트(22)의 외경 사이 공간으로 리스트릭터(60)를 가압하여 리스트릭터(60)에 의한 피니언 샤프트(22)의 구속 상태를 해제시키는 인서터(70)가 장착된다.For this purpose, the restrictor 60 is pressed into the space between the inlet inner diameter of the connector 42 and the outer diameter of the pinion shaft 22 to release the restraint state of the pinion shaft 22 by the restrictor 60. The inserter 70 is mounted.

따라서, 도 6에 도시된 바와 같이 작업자가 푸시조작단(72)을 일정 힘 이상 밀게 되면, 푸시단(71)이 리스트릭터(60)를 밀어주게 됨으로써, 피니언 샤프트(22)의 제1락킹홈(25)에 삽입되어 있던 리스트릭터(60)의 제1구속단(61)이 제1락킹홈(25)으로부터 빠져나오게 되어, 정비 작업 등을 위하여 프로펠러 샤프트(10)와 디퍼런셜(20)의 피니언 샤프트(22) 간을 용이하게 분리시킬 수 있다.Therefore, as shown in FIG. 6, when the operator pushes the push operation stage 72 with a certain force or more, the push stage 71 pushes the restrictor 60, thereby forming the first locking groove of the pinion shaft 22. The first restraining end 61 of the restrictor 60 inserted in (25) comes out of the first locking groove 25, and the pinion of the propeller shaft 10 and the differential 20 is removed for maintenance work, etc. The shafts 22 can be easily separated.
