Field of the Invention The present invention relates to a tow device mounting structure for a vehicle, and more particularly, to form a front through hole and a rear through hole to fix a shaft to a tow device of a vehicle in a beam formed by roll forming. In this case, the diameter of the front through hole formed in the front of the beam is larger than that of the rear through hole, and the front through hole is used as a punching hole for forming the rear through hole, thereby increasing the degree of processing of the rear through hole and The present invention relates to a vehicle traction device mounting structure capable of improving the assembly and rigidity of the shaft installed in the rear through hole and productivity in the production stage of the vehicle.

또한, 후면 관통홀보다 큰 직경으로 형성되는 전면 관통홀에는 중앙에 샤프트 결합홀이 형성되는 샤프트링을 구비하여, 샤프트를 전면 관통홀과 후면 관통홀 사이에 견고하게 고정 결합시킬 수 있도록 한 자동차용 견인장치 취부구조에 관한 것이다.
In addition, the front through hole formed with a diameter larger than the rear through hole is provided with a shaft ring in which a shaft coupling hole is formed in the center, so that the shaft can be firmly fixed between the front through hole and the rear through hole. Towing device mounting structure.

일반적으로 차량은 사고나 고장 등에 의해 자력으로 움직이지 못할 경우 견인을 하게 되는 것이다.In general, a vehicle is towed when it cannot move by itself due to an accident or breakdown.

이와 같은 차량의 견인 방법에는 다양한 종류가 있으며, 차량의 특성이나 상태에 따라 각각 다르게 견인하게 되는 것이다.There are various types of towing methods of such a vehicle, and the towing method of the vehicle is towed differently according to the characteristics or the state of the vehicle.

견인 차량에 의해 차량을 견일 할 경우 차량에 구비되는 견인고리를 견인 차량에 연결하여 견인하게 되는 것이다.When the vehicle is towed by the towing vehicle, the towing ring provided in the vehicle is towed by the towing vehicle.

그리고, 차량의 견인고리가 평상시에 차량에 설치되지 않고 차량의 사고시와 같이 견인이 필요할 때에만 차량에 설치하는 경우 아이볼트를 차량의 빔에 설치되는 샤프트에 결합하여 차량을 견인하게 되는 것이다.In addition, when the tow ring of the vehicle is not installed in the vehicle normally but is installed in the vehicle only when towing is required, such as in an accident of the vehicle, the eye bolt is towed to the shaft by being installed on the shaft installed in the beam of the vehicle.

즉, 차량의 범퍼 내부에 구비되는 빔에 관통홀을 형성하고, 내부에 아이볼트가 결합되는 샤프트를 빔의 관통홀에 결합시켜 차량을 견인하게 되는 것이다.That is, a through hole is formed in the beam provided in the bumper of the vehicle, and the shaft to which the eye bolt is coupled therein is coupled to the through hole of the beam to tow the vehicle.

특히, 근래에는 차량의 범퍼 내부에 구비되는 빔을 형성할 때, 롤러 사이에 가공하고자 하는 판재를 넣어 파이프나 형강 형태로 빔을 형성하는 롤 포밍공법으로 생산하기 때문에 빔에 전면 관통홀과 후면 관통홀을 형성하여, 전면 관통홀과 후면 관통홀 샤프트를 결합시키게 되는 것이다.In particular, in recent years, when forming a beam provided in the bumper of the vehicle, it is produced by the roll forming method of forming a beam in the form of a pipe or a section steel by inserting a sheet to be processed between the rollers, so that the front through hole and the rear through the beam By forming a hole, the front through hole and the rear through hole shaft are combined.

또한, 전면 관통홀과 후면 관통홀을 대응되게 형성하기 위해 전면 관통홀을 1차로 형성한 후 2차로 전면 관통홀을 통해 후면 관통홀을 형성할 경우, 관통홀을 형성하는 펀치에 의해 전면 관통홀이 훼손되며, 또한 후면 관통홀이 정밀하게 형성되지 못하는 문제점도 있었다.
In addition, when the front through hole is formed first to form the front through hole and the rear through hole correspondingly, and when the rear through hole is formed through the front through hole secondly, the front through hole is formed by the punch forming the through hole. This is damaged, there was also a problem that the back through hole is not formed precisely.

따라서 본 발명의 목적은 전면 관통홀과 후면 관통홀을 대응되게 형성할 수 있도록, 빔의 전면에 형성되는 전면 관통홀의 직경을 후면 관통홀의 직경보다 크게 형성하여, 전면 관통홀을 후면 관통홀을 형성하는 펀치 집입용 홀로 사용하며, 후면 관통홀보다 큰 직경으로 형성되는 전면 관통홀에는 중앙에 샤프트 결합홀이 형성되는 샤프트링을 구비하여, 샤프트를 전면 관통홀과 후면 관통홀 사이에 견고하게 고정 결합시킬 수 있도록 형성하며, 후면 관통홀의 가공 정도를 높여 전면 관통홀과 후면 관통홀에 설치되는 샤프트의 조립성과 강성 및 차량의 생산단계에서 생산성을 향상시킬 수 있도록 함으로써, 롤 포밍 공법으로 형성되는 빔의 전면 관통홀과 후면 관통홀을 형성할 경우, 전면 관통홀과 후면 관통홀을 각각 전면과 후면에 형성하여야 하기 때문에 서로 대응되게 형성하기 어려운 문제점과 전면 관통홀과 후면 관통홀을 대응되게 형성하기 위해 전면 관통홀을 1차로 형성한 후 2차로 전면 관통홀을 통해 후면 관통홀을 형성할 경우, 관통홀을 형성하는 펀치에 의해 전면 관통홀이 훼손되며, 또한 후면 관통홀이 정밀하게 형성되지 못하는 문제점을 효과적으로 해결할 수 있도록 한 자동차용 견인장치 취부구조를 제공하는데 있다.Therefore, an object of the present invention is to form a diameter of the front through hole formed in the front of the beam to be larger than the diameter of the rear through hole, so that the front through hole and the rear through hole correspondingly formed, the front through hole to form the rear through hole It is used as a punch insertion hole, and the front through hole formed with a diameter larger than the rear through hole has a shaft ring in which a shaft coupling hole is formed in the center, and the shaft is firmly fixed between the front through hole and the rear through hole. It is formed so that the processing of the rear through-holes can be improved, so that the assembly and rigidity of the shafts installed in the front and rear through-holes can be improved and the productivity in the production stage of the vehicle can be improved. In case of forming front through hole and rear through hole, front through hole and rear through hole should be formed in front and rear respectively It is difficult to form the door to correspond to each other, and to form the front through hole and the rear through hole to correspond to the first and then form the through hole when forming the rear through hole through the front through hole secondly.
