일반적으로 차량의 조향을 위해 설치되는 차량용 조향장치는 조향핸들과 스티어링 튜브 및 스티어링 샤프트와 스티어링 기어로 이루어져 고정 브라켓에 의해 차체에 연결 설치되어 구성된다.In general, a vehicle steering apparatus installed for steering of a vehicle includes a steering wheel, a steering tube, a steering shaft, and a steering gear, which is connected to the vehicle body by a fixing bracket.
상기와 같은 일반적인 조향장치는 운전자의 조향핸들 조작에 의해 스티어링 튜브와 스티어링 샤프트가 회전하여 스티어링 기어의 맞물림 동작에 의해 링키지의 연계 동작에 의해 차량의 주행 방향을 전환하는 데 사용하고 있다.The general steering device as described above is used to change the driving direction of the vehicle by the linkage of the linkage by the steering operation of the steering tube and the steering shaft by the steering wheel operation of the driver to engage the steering gear.
또한 상기와 같은 조향장치는 차량의 충돌시 운전석 전면에 설치되는 조향핸들과 운전자와의 충돌에 의한 충격을 흡수하여 안전사고를 미연에 방지할 수 있도록 스티어링 샤프트와 스티어링 튜브 사이에 충돌 에너지 흡수장치를 적용하고 있다.In addition, the steering device as described above has a collision energy absorbing device between the steering shaft and the steering tube to absorb the impact of the collision between the steering wheel and the driver installed in the front of the driver's seat during the collision of the vehicle to prevent a safety accident. It is applied.
이와 같은 목적으로 이용되는 종래의 차량용 스티어링 칼럼튜브의 충격에너지 흡수장치를 보면 제1도에서 보는 바와 같이 조향핸들 쪽으로 연결되며 내부로 스티어링 어퍼 샤프트(11)와 로우 샤프트(12)가 설치되는 스티어링 칼럼(10)의 외측튜브(13)와 내측튜브(14)사이에 걸림볼(15), (15')을 설치하여 브라켓(16)을 이용하여 차체에 고정 설치하여 구성하였다.Looking at the impact energy absorbing device of a conventional steering column tube for a vehicle used for this purpose as shown in Figure 1 is connected to the steering wheel steering column in which the steering upper shaft 11 and the low shaft 12 is installed inside The locking balls 15 and 15 'were installed between the outer tube 13 and the inner tube 14 of 10 so as to be fixed to the vehicle body using the bracket 16.
따라서 상기와 같은 종래의 장치에서는 차량의 충돌시 조향핸들에 가해지는 충격이 외측튜브(13)에 전달되면 상기 내측튜브(14)와의 사이에 삽입 설치되는 걸림볼(15),(15')의 마찰간섭동작에 의해 조향 핸들에 가해지는 충격에너지를 흡수함과 동시에 상기 스티어링 어퍼 샤프트(11)와 로우 샤프트(12)사이에서 2차로 충격을 흡수하므로서 조향핸들에 가해지는 충격에너지를 약화시켜 운전자를 안전사고로부터 보호할 수 있게 하고 있으나 이는 걸림볼을 설치하면서 어퍼 및 로우 샤프트에 또 다른 충격 흡수구조를 병행 설치되어야 기능이 가능해지며 부품수와 조립공정수의 증가로 조립 작업성이 떨어지며, 구조가 복잡하여 제조원가를 상승시키는 문제점이 있었다.Therefore, in the conventional apparatus as described above, when the impact applied to the steering wheel during the collision of the vehicle is transmitted to the outer tube 13, the engaging balls 15 and 15 'are inserted into and installed between the inner tube 14. The driver absorbs the impact energy applied to the steering wheel by friction interference and simultaneously absorbs the impact between the steering upper shaft 11 and the low shaft 12 to weaken the impact energy applied to the steering wheel. Although it is possible to protect from safety accidents, it is possible to function by installing another shock absorbing structure on the upper and low shafts while installing the catching ball, and the assembly workability is reduced due to the increase in the number of parts and the number of assembly processes. There is a problem of increasing the manufacturing cost is complicated.
본 고안은 상기와 같은 종래의 문제점을 보완하고자 차량의 스티어링 칼럼 튜브의 외측튜브와 내측튜브 사이에 상측과 하측의 직경이 다른 충격 흡수용 부시를 설치하고 상기 충격흡수용 부시의 직경이 작은 상측부는 외측튜브와 내측튜브 사이로 삽입되어 1차로 충격을 흡수하게 하고, 직경이 큰 하측부를 캡으로 내측튜브와 접하도록 고정 설치하여 2차로 층격을 흡수하여 간단한 구조로서 차량의 충돌시 발생하는 스티어링 칼럼 충격에너지를 흡수하여 운전자를 보호하면서 구조도 간소화시켜 제작이 용이하고, 제작원가를 절감시킬 수 있게 하는데 있다.The present invention provides a shock absorbing bush having a different diameter of the upper side and the lower side between the outer tube and the inner tube of the steering column tube of the vehicle, and the upper portion of the small diameter of the shock absorbing bush to compensate for the above problems. It is inserted between the outer tube and the inner tube to absorb shock firstly, and the lower part with a large diameter is fixedly installed to contact the inner tube with a cap to absorb the lamella secondly. It is designed to simplify the structure and reduce the manufacturing cost by protecting the driver while protecting the driver.
