Description

조향핸들의 충격흡수장치Steering handle shock absorber

본 발명은 자동차의 조향핸들에 관한 것으로, 특히 자동차의 주행중에 충돌이나 추돌사고로 인해 운전자의 머리부위나 가슴부위가 조향핸들에 부딪칠 때에 그 충격을 적절히 흡수해서 운전자의 상해를 경감시켜줄 수 있도록 조향핸들에 내장된 조향핸들의 충격흡수장치에 관한 것이다.크게 함과 동시에 조작기구의 운동방향을 바꾸어 링크기구에 전달하는 기어장치 및, 기어 기구의 작동을 앞바퀴에 전달하고 또 좌우 바퀴의 관계위치를 바르게 지지하기 위해 피트먼 아암과 드래그 아암, 너클 아암 및 타이 로드 등으로 구성된 링크기구로 이루어져 있다.The present invention relates to a steering wheel of an automobile, and in particular, when the head or chest of the driver hits the steering wheel due to a collision or collision while driving the vehicle, the shock can be appropriately absorbed to reduce the driver's injury. The present invention relates to a shock absorbing device of a steering wheel integrated in a steering wheel. A gear device which increases the size of the steering wheel and changes the direction of movement of the control device and transmits it to the link mechanism, and transmits the operation of the gear mechanism to the front wheels, and the relation positions of the left and right wheels It consists of a link mechanism consisting of a pitman arm, a drag arm, a knuckle arm and a tie rod to properly support the gear.

그러나 상기와 같은 종래의 완충장치는 운전자의 신체가 직접적으로 부딪치는 조향핸들에 설치되어 있는 것이 아니고 조향축에 장착되어 있기 때문에 운전자가 조향핸들에 직접적으로 부딪치는 과정에 상해를 입을 염려가 있었고, 이 때문에 운전자를 보다 안전하게 보호해주기가 미흡하다고 하는 결점이 있었다. 이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 자동차의 충돌이나 추돌사고시에 운전자의 신체가 직접적으로 부딪치는 조향핸들에 설치되어 충격을 적절히 흡수해서 운전자를 보다 안전하게 보호할 수 있을 뿐만 아니라 구조가 간단하면서도 충격흡수하중의 조절도 용이하도록 된 조향핸들의 충격흡수장치를 제공함에 그 목적이 있다.However, the conventional shock absorber as described above is not installed on the steering wheel that the driver's body directly hits, but is mounted on the steering shaft, so that the driver may be injured in the process of directly hitting the steering wheel. For this reason, there was a drawback that it was insufficient to protect the driver. Accordingly, the present invention has been made in view of the above circumstances, and is installed on a steering wheel in which a driver's body directly hits a vehicle in a collision or collision accident, so as to appropriately absorb shock and protect the driver more safely. The purpose of the present invention is to provide a shock absorbing device of a steering wheel, which is simple and facilitates the adjustment of the shock absorbing load.

도 1은 본 발명에 따른 충격흡수장치가 장착된 조향핸들의 단면도이고,1 is a cross-sectional view of a steering wheel equipped with a shock absorbing device according to the present invention,

상기한 바의 목적을 달성하기 위한 본 발명은, 조향핸들의 내부로 돌출되어 조향핸들과 결합되는 조향축의 선단부에 장착되면서 다수개의 플라스틱 핀으로 결합되어 충격을 받으면 변형되면서 충격에너지를 흡수하는 2개의 충격흡수부재를 갖춤과 더불어 상기 제 1 충격흡수부재가 중앙의 타원통부와 이 타원통부의 원주방향을 따라 일체로 절곡형성되면서 원호형상을 이루는 2개의 플랜지부로 이루어지고, 상기 제 2충격흡수부재는 상기 타원통부에 끼워져서 다수개의 플라스틱 핀으로 결합되는 타원통부와 이 타원통부의 원주방향을 따라 일체로 절곡형성되면서 원호형상을 하고서 상기 플탠지부에 체결되는 2개의 플랜지부를 갖춘 구조로 되어 있다. 그리고 상기 제 2 충격흡수부재(4)도 상기 제 1 충격흡수부재(3)와 유사한 형상으로 형성되어 있는 데, 즉 상기 타원통부(3a)의 직경보다 상대적으로 작은 직경을 갖고서 중앙에 위치된 타원통부(4a)와, 이 타원통부(4a)의 원주방향을 따라 일체로 절곡형성되면서 원호형상을 이루는 2개의 플랜지부(4b)를 갖춘 구조로 되어 있다.The present invention for achieving the above object, two protruding into the steering handle is mounted to the distal end of the steering shaft coupled to the steering handle and coupled to a plurality of plastic pins to be deformed when the shock is absorbed by two In addition to having a shock absorbing member, the first shock absorbing member is formed of an elliptical cylinder in the center and two flanges forming an arc shape while being integrally bent along the circumferential direction of the elliptical cylinder, and the second shock absorbing member The elliptic cylinder portion is inserted into the elliptic cylinder portion is coupled to a plurality of plastic pins and is formed integrally bent along the circumferential direction of the elliptic cylinder portion has a structure having an arc shape and two flanges fastened to the flange portion. . The second shock absorbing member 4 is also formed in a shape similar to that of the first shock absorbing member 3, that is, an ellipse positioned at the center with a diameter relatively smaller than that of the elliptic cylinder portion 3a. A cylindrical portion 4a and two flange portions 4b which are integrally bent along the circumferential direction of the elliptic cylindrical portion 4a to form an arc shape are provided.

이상 설명한 바와 같이 본 발명에 따른 조향핸들의 충격흡수장치에 의하면, 자동차의 주행중에 충돌이나 추돌사고로 인해 운전자의 신체가 조향핸들에 부딪치게 되면, 조향축에 장착된 충격흡수부재의 적절한 변형으로 충격을 흡수하여 저감시켜주게 되므로, 운전자가 조향핸들에 부딪칠 때에 받게되는 충격을 완화시켜 운전자의 상해를 효과적으로 경감시켜줄 수 있게 되고, 또 구조도 간단하여 저렴하게 제작할 수 있는 효과가 있다.As described above, according to the shock absorbing device of the steering wheel according to the present invention, if the driver's body hits the steering wheel due to a collision or collision accident while driving the vehicle, the shock by the appropriate deformation of the shock absorbing member mounted on the steering shaft Since it absorbs and reduces the pressure, the impact received when the driver hits the steering wheel can be alleviated to effectively reduce the injury of the driver, and the structure is simple and inexpensive.
