본 발명은 종래의 맥퍼슨 스트럿 방식의 현가장치를 구비한 차량에서, 차량의 전복위험 발생시 차량의 윤거를 순간적으로 증대시켜서, 차량의 전복을 방지하도록 함으로써, 차량의 안전성을 크게 향상시키고 상품성을 증대시킬 수 있도록 한다.According to the present invention, in a vehicle equipped with a conventional McPherson strut type suspension device, when the risk of vehicle overturning occurs, the vehicle is temporarily increased to prevent vehicle overturning, thereby greatly improving the safety of the vehicle and increasing the merchandise. To help.

도 1을 참조하면, 본 발명 실시예는 스트럿(1)에 대하여 너클(3)이 차량의 전후방향을 따르는 축을 기준으로 회동 가능한 상태로 결합되도록 상기 스트럿(1)과 너클(3)을 고정하는 제1고정부재(5)와; 상기 스트럿(1)에 대한 상기 너클(3)의 회동을 마찰력으로 억제하도록 상기 스트럿(1)과 상기 너클(3)을 고정하는 제2고정부재(7)와; 폭발력에 의하여, 상기 제2고정부재(7)가 제공하는 마찰력을 극복하고 상기 너클(3)의 하측이 차량의 중심으로부터 벌어지는 방향으로 회동되도록, 상기 너클(3)과 상기 제2고정부재(7) 사이에 구비된 폭발력제공수단과; 상기 너클(3)이 상기 스트럿(1)에 대하여 회동되는 것을 허용 및 가이드하도록 상기 너클(3)에 구비된 가이드홀(9)을 포함하여 구성된다.Referring to FIG. 1, the embodiment of the present invention secures the strut 1 and the knuckle 3 so that the knuckle 3 is coupled to the strut 1 in a rotatable state based on an axis along the front and rear directions of the vehicle. A first fixing member 5; A second fixing member (7) for fixing the strut (1) and the knuckle (3) to suppress the rotation of the knuckle (3) with respect to the strut (1) with frictional force; By the explosive force, the knuckle (3) and the second fixing member (7) so as to overcome the frictional force provided by the second fixing member (7) and to rotate the lower side of the knuckle (3) away from the center of the vehicle. Explosive force providing means provided between; It comprises a guide hole (9) provided in the knuckle (3) to allow and guide the knuckle (3) to be rotated with respect to the strut (1).

즉, 상기 너클(3)은 상기 스트럿(1)에 상기 제1고정부재(5)에 의해서만 체결된 상태에서는 상기 스트럿(1)에 대하여 회동이 가능하지만, 상기 제2고정부재(7)가 함께 체결되어 마찰력을 형성하게 됨으로써, 보통의 차량 주행시에는 상기 너클(3)이 상기 제1고정부재(5)와 제2고정부재(7)에 의해 상기 스트럿(1)에 대하여 회동되지 않고 견고한 장착상태를 가지지만, 상기 폭발력제공수단에 의해 폭발력이 제공되면, 상기 너클(3)이 상기 제1고정부재(5)를 축으로 회동될 수 있도록 구성한 것이다.That is, the knuckle 3 is rotatable with respect to the strut 1 in a state where only the first fixing member 5 is fastened to the strut 1, but the second fixing member 7 is together. Since the knuckle (3) is not rotated with respect to the strut (1) by the first fixing member 5 and the second fixing member (7) during normal vehicle driving by being fastened to form a friction force, the solid state of mounting However, if the explosive force is provided by the explosive force providing means, the knuckle (3) is configured so that the first fixing member (5) can be rotated about the axis.

물론, 상기 너클(3)의 회동범위는 상기 가이드홀(9)에 의해 적절한 수준으로 제한된다.Of course, the range of rotation of the knuckle 3 is limited to an appropriate level by the guide hole 9.

참고로, 도 1에서 스트럿의 상단부는 차체마운팅부(19)에 고정되고, 상기 너클의 하측은 로어암(21)을 통해 차체에 지지되어 있다.For reference, in FIG. 1, the upper end of the strut is fixed to the vehicle body mounting portion 19, and the lower side of the knuckle is supported by the vehicle body through the lower arm 21.

본 실시예에서, 상기 제1고정부재(5)와 상기 제2고정부재(7)는 상하로 배치되어 각각 상기 스트럿(1)과 너클(3)을 관통하여 체결되는 체결볼트로 이루어지고, 상기 너클(3)의 가이드홀(9)은 상기 제2고정부재(7)가 관통되는 구멍으로부터 차체 내측을 향하여 원호형으로 연장되어 형성된다.In the present embodiment, the first fixing member 5 and the second fixing member 7 are disposed up and down, and are composed of a fastening bolt which is fastened through the strut 1 and the knuckle 3, respectively, The guide hole 9 of the knuckle 3 extends in an arc shape from the hole through which the second fixing member 7 penetrates toward the inside of the vehicle body.

따라서, 상기 폭발력제공수단에 의해 폭발력이 제공되면, 상기 너클(3)은 상기 가이드홀(9)이 허용하는 범위 내에서 상기 스트럿(1)에 대하여 회동됨으로써, 휠(11)의 하측이 차량의 외측을 향하여 벌어지도록 함으로써, 차량의 윤거를 실질적으로 증가시키게 되는 것이다.Therefore, when the explosive force is provided by the explosive force providing means, the knuckle (3) is rotated relative to the strut (1) within the range allowed by the guide hole (9), so that the lower side of the wheel (11) of the vehicle By spreading outwards, the leaching of the vehicle is substantially increased.

물론, 상기 제1고정부재(5)와 제2고정부재(7)는 상기와 같은 체결볼트 이외에 핀 이나, 특수 형상의 샤프트 등으로 구성할 수도 있을 것이다.Of course, the first fixing member 5 and the second fixing member 7 may be composed of a pin, a special shaped shaft, or the like in addition to the fastening bolt as described above.

본 실시예에서, 상기 폭발력제공수단은 상기 제2고정부재(7)를 기준으로 상기 너클(3)의 차체 외측 부분에, 상기 제2고정부재(7)에 인접하여 충전된 폭발물(13)과, 차량의 전복 가능 상황을 감지하는 센서(15)와, 상기 센서(15)의 신호를 받아 상기 폭발물(13)을 폭발시키도록 제어하는 컨트롤러(17)를 포함하여 구성된다.In the present embodiment, the explosive force providing means includes an explosive material 13 charged adjacent to the second fixing member 7 at an outer portion of the vehicle body of the knuckle 3 based on the second fixing member 7. It includes a sensor 15 for detecting a possible rollover of the vehicle, and a controller 17 for receiving the signal of the sensor 15 to control the explosives 13 to explode.

즉, 상기 너클(3)에 차체 외측으로부터 상기 제2고정부재(7)를 향하여 개구된 홈을 형성하고, 여기에 상기 폭발물(13)을 충전시키는 구조를 취하도록 함으로써, 상기 폭발물(13)이 상기 컨트롤러(17)에 의해 폭발되면, 상기 제2고정부재(7)는 고정된 위치에 있으므로, 상대적으로 상기 너클(3)의 하측이 외측으로 벌어지는 방향으로 회동되게 되는 것이다.That is, the explosives 13 are formed by forming a groove in the knuckle 3 that is open from the outside of the vehicle body toward the second fixing member 7 and filling the explosives 13 therein. When exploded by the controller 17, the second fixing member 7 is in a fixed position, so that the lower side of the knuckle 3 is rotated in a direction of spreading outward.

상기 차량의 전복 가능 상황을 감지하는 센서(15)로는, 기울기센서나 가속도센서 등이 사용될 수 있을 것이다.As the sensor 15 for detecting a rollover possibility of the vehicle, a tilt sensor or an acceleration sensor may be used.

상기한 바와 같이 구성된 본 발명의 차량의 전복 방지 장치는, 차량이 주행중 전복 가능 상황이 되면, 상기 센서(15)에서 이를 감지하여 상기 컨트롤러(17)로 신호를 송출하고, 상기 컨트롤러(17)는 상기 센서(15)로부터의 신호를 받아, 차량의 전복 가능성이 높다고 판단되면, 상기 폭발물(13)을 폭발시킨다.In the vehicle anti-overturning apparatus of the present invention configured as described above, when the vehicle is capable of overturning while the vehicle is running, the sensor 15 detects this and transmits a signal to the controller 17. The controller 17 Upon receiving a signal from the sensor 15 and determining that the vehicle is likely to be rolled over, the explosive 13 is exploded.

상기 폭발물(13)이 폭발되면서 폭발력을 발생시키면, 보통의 상태에서는 상기 제2고정부재(7)에 의해 상기 너클(3)과 상기 스트럿(1) 사이에 형성되던 마찰력을 극복하고, 상기 너클(3)이 상기 스트럿(1)에 대하여 상기 가이드홀(9)이 허용하는 범위 내에서 회동됨으로써, 차량의 윤거가 도 2에 도시된 바와 같이 좌측의 상태로부터 우측의 상태와 같이 변화하게 된다.When the explosive 13 is exploded to generate an explosive force, in a normal state to overcome the friction force formed between the knuckle (3) and the strut (1) by the second fixing member (7), the knuckle ( As 3) is rotated within the range allowed by the guide hole 9 with respect to the strut 1, the vehicle leaching changes from the state on the left side to the state on the right side as shown in FIG.

차량의 윤거 변화는 차량의 전복 방지에 가장 큰 영향을 미치는 인자로서, 상기한 바와 같이 차량의 전복 위험 상황에서 급격히 증가시킨 차량의 윤거는 차량의 전복을 매우 효과적으로 억제해 주게 된다.The change in vehicle rolling is the most influential factor in the vehicle overturn prevention. As described above, the vehicle leaching rapidly increased in a dangerous situation of the vehicle overturning, thereby effectively suppressing the vehicle overturning.
