Description

자동차 조향휠의 내구성 테스트장치Durability test device of automobile steering wheel

일반적으로 조향장치(steering system)는 자동차의 주행방향을 운전자가 조향핸들을 돌려 자유로이 바꾸는 장치로서 조향휠, 조향컬럼, 조향축, 조향기어, 조향링키지등으로 구성되어 있다.In general, a steering system is a device that a driver freely changes the driving direction of a vehicle by turning a steering wheel. The steering system includes a steering wheel, a steering column, a steering shaft, a steering gear, a steering linkage, and the like.

이와같이 자동차의 주행방향을 운전자가 자유로이 바꿀 수 있도록 하는 조향장치(steering system)는 자동차의 주행방향을 바꾸기 위한 조향핸들로서 운전자가 앞바퀴가 어떤 움직임을 하고 있는가를 감지하게 되는 조향휠(steering wheel), 조향휠의 조작력을 조향기어 박스의 조향기어에 전달하는 축인 조향축(steering shaft), 조향휠의 회전운동을 직각에 가까운 각도로 바꿈과 동시에 조향력을 증대시켜 피트먼 암에 전달하는 조향기어(steering gear) 및 자동차의 진행방향을 바꾸는 장치중에서 조향기어로부터 힘을 앞바퀴에 전달하는 메커니즘의 총칭으로서, 아이들암, 피트먼암, 너클암, 타이로드등으로 이루어진 조향링키지(steering linkage)로 구성되어 있다.The steering system that allows the driver to freely change the driving direction of the vehicle is a steering wheel for changing the driving direction of the vehicle. A steering wheel or steering that detects the driver's movement of the front wheel. Steering shaft, which is the axis that transmits the operating force of the wheel to the steering gear of the steering gear box, and steering gear that changes the rotational movement of the steering wheel to the angle close to the right angle and increases steering power to the Pitman arm. And a mechanism that transmits the force from the steering gear to the front wheel among the devices for changing the direction of movement of the vehicle, and is composed of a steering linkage consisting of an idle arm, a pitman arm, a knuckle arm, a tie rod, and the like.

이렇게 구성된 조향장치는 조향축의 플렉시블 조인트(스티어링 조인트, 유니버셜 조인트)가 조향기어 박스의 피니언 샤프트와 결합되어 조향휠의 회전운동을 조향링키지를 통하여 바퀴에 전달하게 된다.In this configuration, the steering shaft flexible joint (steering joint, universal joint) is coupled with the pinion shaft of the steering gear box to transmit the rotational movement of the steering wheel to the wheel through the steering linkage.

이리하여 조향장치로 바퀴의 방향을 조종하여 주행방향을 결정하게 된다.Thus, the steering device is used to control the direction of the wheel to determine the driving direction.

상기처럼 조향휠의 조작에 의해 바퀴의 주행방향이 변하게 되는 것으로, 좌/우로 진행방향을 바꾸기 위해서는 조향휠을 좌/우로 돌려 바퀴를 왼쪽 또는 오른쪽으로 소정각도 움직인 다음에 곡선을 그리면서 선회하여 진행방향을 바꾸어야 한다.As described above, the driving direction of the wheel is changed by the operation of the steering wheel. To change the traveling direction to the left / right, the steering wheel is rotated to the left or right by a predetermined angle to turn the steering wheel to the left or right, You must change the direction of travel.

상기 조향휠은 테를 이루는 림(rim), 테에서 내측으로 뻗어나가 살을 이루는 스포(spoke)크 및 스포크가 모이는 허브(hub)로 구성된 것이다.The steering wheel is composed of a rim that forms a rim, a spoke that extends inwardly from the rim, and a hub where spokes gather.

상기 허브에는 조향휠의 조작력을 조향기어에 전달하는 조향축이 설치된다.The hub is provided with a steering shaft for transmitting the operating force of the steering wheel to the steering gear.

그런데 상기와 같이 주행방향을 바꾸기 위해서 조향휠을 돌릴 때 조향축에는 상당한 토션(torsion)이 작용하게 된다.However, when the steering wheel is turned to change the driving direction as described above, a significant torsion is applied to the steering shaft.

이러한 토션은 조향휠의 내구성에 영향을 미치게 되는데 종래 토션을 측정하여 조향휠의 내구성을 테스트하지 않았기 때문에 조향휠의 내구성에 대한 신뢰도를 확보할 수 없는 문제점이 있었다.This torsion affects the durability of the steering wheel. Since the conventional torsion was not measured and the durability of the steering wheel was not tested, there was a problem that reliability of the steering wheel could not be secured.

따라서 본 발명은 상기한 문제점을 고려하여 조향축에 주기적인 토션을 가하여 조향휠 내구성 테스트를 하므로써 조향휠의 내구성에 대한 신뢰도를 확보하고자 한 자동차 조향휠의 내구성 테스트장치를 제공함에 그 목적이 있는 것이다.Accordingly, an object of the present invention is to provide a durability test apparatus for an automobile steering wheel to secure reliability of steering wheel durability by applying a steering wheel durability test by applying a periodic torsion to a steering shaft in view of the above problems. .

상기한 본 발명의 목적은 조향휠이 고정설치되는 지그; 상기 조향휠의 조향축을 잡는 아암; 및 상기 조향축에 토션을 가하는 실린더로 조향휠의 내구성 테스트장치를 구성하므로써 달성되는 것이다.An object of the present invention described above is a jig in which a steering wheel is fixedly installed; An arm for holding a steering shaft of the steering wheel; And it is achieved by configuring the durability test apparatus of the steering wheel with a cylinder to torsion to the steering shaft.
