It relates to a rear axle bush durability inspection apparatus of a vehicle configured to measure the durability of the rear axle front bush and the rear axle rear bush.

일반적으로, 후륜 구동 차량에는 첨부 도면 도 1에 도시된 바와 같이 뒷차축(10)에 추진축(12)에서의 동력을 직각 또는 그것에 가까운 각도로 바꾸어 전달함과 동시에 감속하여 토크를 증대시키는 종감속기어(미도시)와, 주행중에 선회하거나 노면에 요철이 있는 경우에 좌우의 바퀴에 회전차가 생길 필요가 있을 때 자동적으로 회전차를 주어서 원활한 주행을 할 수 있도록 하는 차동기어가 일체로 액슬 하우징(20)에 장치되어 설치된다.In general, the rear-wheel drive vehicle is a longitudinal reduction gear that decelerates and increases torque while simultaneously transferring power from the propulsion shaft 12 to the rear axle 10 at a right angle or close to the rear axle 10 as shown in FIG. 1. (Not shown) and the axle housing 20 is integrally provided with a differential gear that automatically gives a turning wheel when a turning wheel needs to be formed on the left and right wheels when turning or driving unevenness on the road. It is installed and installed in).

그리고, 상기 액슬 하우징(20)의 앞쪽 일측에 형성된 제 1부시고정브라켓트(22)의 내부에는 뒷차축프론트부시(30)가 삽입되어 차체바디(50)에 상하방향으로 체결 고정되고, 상기 액슬 하우징(20)의 뒤쪽 좌우측에는 차체바디(50)에 용착된 제 2부시고정브라켓트(52)의 내부에 삽입된 한 쌍의 뒷차축리어부시(40)가 전후방향으로 체결 고정되어 상기 액슬 하우징(20)을 고정 지지하는 동시에 자동차의 주행중에 상하 방향으로 작용되는 충격 및 진동이 흡수되도록 되어 있다.In addition, a rear axle front bush 30 is inserted into the first abutment bracket 22 formed at one front side of the axle housing 20 to be fastened and fixed to the body body 50 in the vertical direction, and the axle housing The rear axle rear bush 40 inserted into the second part fixing bracket 52 welded to the body body 50 is fastened and fixed in the front and rear directions at the rear left and right sides of the axle housing 20. ) And at the same time absorb shocks and vibrations acting in the vertical direction while the vehicle is running.

한편, 상기 뒷차축프론트부시(30)는 원통형 형상으로 된 금속성 재질의 내측부재(32)와, 상기 내측부재(32)의 외주면에 끼워지고 하단에 프랜지부(34a)가 형성된 완충부재(34)와, 상기 완충부재(34)의 외주면에 끼워지고 하단에 프랜지부(36a)가 형성된 금속성 재질의 외측부재(36)로 구성된 것으로, 체결부재(14)에 의해 설치 고정된 상태에서 자동차 주행시의 상하 요동에 의해 축방향으로 반복적인 피로하중이나 변형력이 작용되는 것이다.On the other hand, the rear axle front bush 30 is the inner member 32 of the metallic material of the cylindrical shape, the buffer member 34 is fitted to the outer peripheral surface of the inner member 32 and the flange portion 34a is formed at the bottom And an outer member 36 made of a metallic material fitted to an outer circumferential surface of the buffer member 34 and having a flange portion 36a formed at a lower end thereof, the upper and lower parts of the vehicle being driven and fixed by the fastening member 14. Repetitive fatigue loads or deformation forces are applied in the axial direction by oscillation.

그리고, 상기 뒷차축리어부시(40)는 내부가 관통된 원통형 부재의 일측 내주면 상에 볼트걸림턱(42a)이 형성된 금속성 재질의 내측부재(42)와, 상기 내측부재(42)의 외주면에 끼워지고 그 일측 단부에 프랜지부(44a)가 형성된 고무재질의 완충부재(44)와, 상기 완충부재(44)의 외주면 상에 끼워져 결합되고 그 일측 단부에 프랜지부(46a)가 형성된 금속성 재질의 외측부재(46)로 구성된 것으로, 설치된 상태에서 자동차 주행시의 상하 요동에 의해 축방향에 대해 직각을 이루는 외주방향으로 반복적인 피로하중이나 변형력을 흡수하게 되는 것이다.In addition, the rear axle rear bush 40 is fitted to an inner member 42 of a metallic material and a bolt engaging jaw 42a formed on one inner circumferential surface of the cylindrical member through which the inside is penetrated, and an outer circumferential surface of the inner member 42. The outer side of the metallic material having a rubber member (44a) formed at one end thereof and being fitted on the outer circumferential surface of the buffer member (44) and having a flange portion (46a) formed at one end thereof. The member 46 is configured to absorb repetitive fatigue loads or deformation forces in the circumferential direction perpendicular to the axial direction due to the vertical swing of the vehicle in the installed state.

그러나, 상기와 같은 뒷차축프론트부시(30)와 뒷차축리어부시(40)와 같은 부품은 자동차의 주행중에 발생되는 상하방향의 요동과 충격 및 진동에 의해 끊임없이 피로하중과 변형력을 받게 되므로 정적하중하(靜的荷重下)에서 최후강도(最後强度)보다 낮은 응력에서 그 부재의 변형이나 파단이 일어나므로, 일정한 내구성을 갖는 뒷차축부시를 설계 또는 선정하여 설치할 수 있도록 상기 뒷차축부시의 내구성을 검사할 수 있는 내구성 검사장치가 요구되었다.However, since the components such as the rear axle front bush 30 and the rear axle rear bush 40 are subject to fatigue load and deformation force constantly by the up-down swing, shock and vibration generated during driving of the vehicle, the static load Since the members are deformed or broken at a stress lower than the ultimate strength at the bottom, the durability of the rear axle bush is designed so that the rear axle bush with constant durability can be designed or selected. There was a need for an endurance tester capable of inspecting.
