볼트 고정형 액슬 케이싱{An axle casing fixed by bolt}An axle casing fixed by bolt}

본 발명은 차량의 액슬 케이싱에 관한 것으로서, 특히 동력이 연결되어 있지 않은 차량의 액슬 케이싱을 고정함에 있어 허브에 파이프를 압입한 후 볼트를 관통시켜 허브와 파이프를 고정시키는 볼트 고정형 액슬 케이싱에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to axle casings for vehicles, and more particularly, to a bolted axle casing for securing a hub and a pipe through a bolt after press-fitting a pipe into a hub in fixing an axle casing of a vehicle that is not powered. .

일반적으로 액슬(Axle)은 굴대, 차축의 뜻으로서, 액슬은 안쪽의 스플라인을 통해 차동기어장치의 사이드 기어 스플라인에 끼워지고, 바깥쪽은 구동바퀴에 연결되어 엔진의 동력을 바퀴에 전달한다. 앞 차축을 프런트액슬, 뒤 차축을 리어액슬이라 한다. 또한 액슬 케이싱(Axle Casing)은 액슬 하우징이라고도 하며, 종감속기어와 차동기어장치 및 액슬을 포함하는 튜브 모양의 고정축이며, 양단부는 스프링의 지지부와 플랜지부가 설치되어 있다. 즉, 리어 액슬 케이싱은 뒤차축을 내장하는 바깥 파이프로서 차량의 후부하중을 지지하는 고정축이다. 중앙부에는 종감속기어와 차동기어를 내장하고, 양단에는 스프링과 브레이크장치의 백플레이트 등의 장치부가 설치되어 있으며 구조상 벤조형, 스플릿형으로 나누어진다.Generally, axle means mandrel and axle. The axle is fitted to the side gear spline of the differential gear device through the inner spline, and the outside is connected to the drive wheel to transmit the engine's power to the wheels. The front axle is called the front axle and the rear axle is called the rear axle. The axle casing is also called an axle housing, and is a tube-shaped fixed shaft including a longitudinal reduction gear, a differential gear device and an axle, and both ends are provided with a spring support part and a flange part. That is, the rear axle casing is a fixed shaft that supports the rear load of the vehicle as an outer pipe having a rear axle. In the center part, the gearbox and the differential gear are built-in, and both ends are equipped with device parts such as back plate of spring and brake device and are divided into benzo type and split type.
