즉, 상기 노즈다이브방지수단(10)은, 상기 쇽업소버(1)와 너트와 볼트에 의해 조립되도록 다수의 관통구(111)가 형성된 하부플레이트(11)와, 상기 하부플레이트(11)의 상부에 위치되며 차체의 프레임에 볼트와 너트에 의해 조립되도록 다수의 관통구(121)가 형성된 상부플레이트(12)와, 상기 상부플레이트(12)와 상기 하부플레이트(11)의 사이를 기밀하게 유지시켜 노즈다이브현상이 발생될 경우 후술하는 콤프레서로부터 공급되는 에어에 의해 팽창되도록 신축성있는 재질로 이루어진 자바라부재(13)로 이루어진다.That is, the nosedive prevention means 10 includes a lower plate 11 having a plurality of through holes 111 formed thereon so as to be assembled by the shock absorber 1, a nut and a bolt, and an upper portion of the lower plate 11. The upper plate 12 and the plurality of through-holes 121 are formed in the frame of the vehicle body to be assembled by bolts and nuts, and the airtightness between the upper plate 12 and the lower plate 11 is kept tight. When the nose dive phenomenon occurs, it is made of a bellows member 13 made of an elastic material to be expanded by air supplied from a compressor to be described later.

또, (20)은 자동차의 주행중에 자동차의 속도가 설정치이상으로 급감속될 경우 작동되어 상기 노즈다이브방지수단(10)으로 에어를 공급하는 콤프레서이고, (30)은 자동차의 차속을 입력받아 차속의 변화율을 연산하여 차속이 설정치 이상으로 급감속될 경우 이를 후술하는 콘트롤러로 제어신호를 송신하는 차속변화율감지센서이다.In addition, 20 is a compressor for supplying air to the nose dive prevention means 10 is operated when the speed of the vehicle is rapidly reduced or more than the set value while driving the vehicle, 30 is the vehicle speed is input to the vehicle speed It is a vehicle speed change rate detection sensor that transmits a control signal to a controller which will be described later when the vehicle speed is rapidly decelerated above the set value by calculating the rate of change.

Will be.

또, 자동차의 주행중에 차속의 급감속으로 인한 노즈다이브현상이 방지되므로써 자동차의 탑승한 승객 및 운전자는 전방으로 몸체가 제쳐지는등의 신체에 충격이 가해지는 경우가 발생되지 않게 되어 안전하고 안락한 주행을 할 수 있게 되는 것이다.In addition, it is possible to prevent the nosedive phenomenon caused by the rapid deceleration of the vehicle while the vehicle is being driven, so that passengers and drivers who ride the vehicle are not shocked to the body such as being pushed forward. You will be able to.

앞에서 설명한 바와 같이 본 발명에 의한 자동차의 자세제어장치에 의하면, 자동차의 주행중에 자동차의 차속이 급격하게 감속될 경우 노즈다이브방지수단으로 에어 가 공급되어 자동차의 차체가 앞방향으로 쏠리는 것을 방지하므로써 자동차에 탑승한 승객 및 운전자의 몸체가 앞방향으로 제쳐지는 것이 방지되어 승객 및 운전자를 안전하게 보호할 수 있다는 매우 우수한 효과가 있게 되는 것이다.As described above, according to the attitude control apparatus of a vehicle according to the present invention, when the vehicle speed of the vehicle is suddenly decelerated while the vehicle is being driven, air is supplied to the nose dive preventing means to prevent the vehicle body from being forwardly moved. The body of the passenger and the driver on board is prevented from being pushed forward so that the passenger and the driver can be safely protected.
