Description
본 발명은 차량에 설치되는 보조브레이크장치에 관한 것으로, 특히 유체의 점성을 이용하여 구동축의 회전속도를 순차적 또는 순간적으로 감소시킴으로써 승차감을 향상시키면서 제동력을 향상시키도록 된 차량의 보조 제동장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary brake device installed in a vehicle, and more particularly, to an auxiliary braking device for a vehicle which improves riding comfort by sequentially or instantaneously decreasing the rotational speed of a drive shaft by using viscosity of a fluid. .
제동장치는 주행하는 자동차를 감속 또는 정지시킴과 아울러 주차상태를 유지하기 위해 사용되는 것으로써 주행중에는 운전석에 마련된 풋브레이크를 조작하여 차량을 감속시키도록 되어 있다.The braking device is used to decelerate or stop a driving car and to maintain a parking state. The braking device is configured to decelerate the vehicle by operating a foot brake provided in the driver's seat while driving.
그런데 이와 같이 일반적으로 차량의 제동력은 정해진 제동장치를 통해서만 얻을 수 있기 때문에 급제동시에는 충분한 제동력을 얻지 못하는 경우가 있고 제동시에는 관성력으로 인해 차체가 진행방향으로 쏠리게 되어 승차감을 저하시킨다는 단점이 있다.However, since the braking force of the vehicle is generally obtained only through a predetermined braking device, there is a case in which a sufficient braking force may not be obtained during rapid braking, and during braking, the vehicle body may be oriented in the traveling direction due to the inertia force, thereby degrading the riding comfort.
이에 본 발명은 상기와 같은 단점을 해결하기 위하여 발명된 것으로, 차량의 구동축에 유체의 저항력에 의해 점진적 또는 순간적으로 제동력을 얻도록 구성된 보조감속장치를 부가설치함으로써 제동력 향상과 함께 승차감 향상에도 도움을 주도록 된 차량의 보조제동장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above disadvantages, by adding an auxiliary deceleration device configured to obtain a braking force gradually or instantaneously by the resistance of the fluid to the drive shaft of the vehicle to help improve the braking force and ride comfort. It is an object of the present invention to provide an auxiliary braking device for a vehicle.

도 1은 본 발명에 따른 보조제동장치의 사용상태도이고, 도 2는 본 발명에 따른 동작원리를 설명하기 위한 평면도로써, 본 발명은 도면에 도시된 것과 같이, 구동축(1)의 소정위치에 기어(2)가 연결설치되고, 이 기어(2)와 맞물리도록 감속수단(3)이 설치되어 이 감속수단(3)에서 발생되는 회전력으로 구동축(1)의 회전속도를 점진적 또는 순간적으로 감소시키도록 구성되어 있다.1 is a state diagram of the auxiliary braking device according to the present invention, Figure 2 is a plan view for explaining the operation principle according to the present invention, the present invention, as shown in the figure, the gear in a predetermined position of the drive shaft (1) (2) is connected, and the reduction means (3) is provided so as to mesh with the gear (2) so that the rotational speed of the drive shaft (1) is gradually or momentarily reduced by the rotation force generated by the reduction means (3). Consists of.
여기서, 상기 보조제동장치(3)는 소정형상을 이룬 하우징(4)과, 이 하우징(4)내에 장착되는 회전체(5), 이 회전체(5)에 방사상으로 복수개 배열설치된 액튜에이터(6), 액튜에이터(6)의 로드선단에 로드의 길이방향으로 부착된 블레이드(7) 및, 끝부분에 기어(8)를 갖추고서 상기 회전체(5)의 하단에 수직방향으로 부착된 회전축(9)을 갖추고 있는 한편, 상기 하우징(4)내에는 점도가 큰 유체가 충만되어 밀봉처리되어 있다.Here, the auxiliary braking device (3) comprises a housing (4) having a predetermined shape, a rotating body (5) mounted in the housing (4), and a plurality of actuators (6) radially arranged on the rotating body (5). A rotary shaft 9 attached to the lower end of the rotor 5 with a blade 7 attached to the rod end of the actuator 6 in the longitudinal direction of the rod and a gear 8 at the end thereof; On the other hand, the housing 4 is filled with a fluid having a high viscosity and sealed.
그리고, 상기 액튜에이터(6)는 전자제어유니트와 연결되어 있는데, 이 전자제어유니트는 운전자의 운전습관, 즉 브레이크페달을 작동시키는 습관을 인식하여 평소의 페달 조작속도보다 빠르게 페달을 조작하거나 정상조작속도일 경우 이를 감지하여 액튜에이터(6)로 제어신호를 인가시키도록 구성되어 있다.In addition, the actuator 6 is connected to the electronic control unit, which recognizes the driver's driving habits, that is, the habit of operating the brake pedal, and operates the pedal faster than the normal pedal operation speed or the normal operation speed. In this case it is configured to detect and apply a control signal to the actuator (6).
또한, 이 전자제어유니트는 운전자의 운전습관외에도 차량의 전방에 거리감지센서를 부착하여 이 거리감지센서에서 인가되는 감응신호에 따라 급제동이 필요한 상황으로 판단되면 엑튜에이터(6)로 제어신호를 인가시키도록 구성할 수도 있다.In addition, the electronic control unit attaches a distance sensor to the front of the vehicle in addition to the driver's driving habits and applies a control signal to the actuator 6 when it is determined that rapid braking is required according to the sensitive signal applied from the distance sensor. It can also be configured to.
따라서 상기 전자제어유니트에서 운전자의 페달속도를 감지하여 평상시의 운전습관보다 빠르게 조작하였음을 감지하면 액튜에이터(6)로 제어전원이 인가되게 되고, 이에 따라 엑튜에이터(6)가 최대로 신장되면서 블레이드(7)를 순간적으로 최대위치까지 위치이동시킴에 따라 블레이드(7)와 유체간의 마찰력이 증가되어 회전축(9)을 통해 구동축(1)으로 저항력을 전달하게 되므로 구동축(1)의 회전속도를 빠르게 감속시키게 된다.Accordingly, when the electronic control unit detects the driver's pedal speed and detects that the driver's pedal is operated faster than usual driving habits, the control power is applied to the actuator 6, and accordingly, the actuator 6 is extended to the maximum and the blade ( By moving the position 7) to the maximum position momentarily, the frictional force between the blade 7 and the fluid is increased to transfer the resistance force to the drive shaft 1 through the rotation shaft 9, thereby rapidly reducing the rotational speed of the drive shaft 1. Let's go.
또한, 전자제어유니트에서 운전자의 페달조작속도가 평소의 운전습관과 비교하여 동일 또는 큰 차이가 없다고 판단되었을 때에는 로드가 점진적으로 신장되도록 엑튜에이터(6)로 제어신호를 인가시키게 되고, 이에 따라 블레이드(7)의 위치가 순차적으로 최대위치로 이동하게 되므로 구동축(1)의 회전속도를 순차적으로 감속시키게 된다.In addition, when it is determined that the driver's pedal operation speed is not the same or large as compared with the usual driving habit, the electronic control unit applies a control signal to the actuator 6 so that the rod is gradually extended. Since the position of (7) is sequentially moved to the maximum position, the rotation speed of the drive shaft (1) is sequentially reduced.
그리고, 운전자가 브레이크페달에서 발을 떼고 정상적인 주행을 하고 있을 때에는 전자제어유니트에서 엑튜에이터(6)의 동작로드를 원위치시키도록 제어신호를 인가시키게 되므로 상기 회전체(5)는 구동축(1)의 회전속도와 동일하게 회전하면서 제동력을 발휘하지 않게 된다.When the driver takes off the brake pedal and is driving normally, the control unit applies a control signal to return the operating rod of the actuator 6 to the electronic control unit. While rotating at the same speed as the rotation speed, the braking force is not exerted.
한편, 상기 회전체(5)의 형상과 크기는 하우징(4)에 충만된 유체의 점성을 고려하여 아이들 동작시에는 구동축(1)과 동일 회전수를 갖도록 하여야 하는데, 이같은 조건을 만족한다면 본 발명에서와 같이 원판형태로 제조하지 않고 다른 형태로 제조해도 무방하며, 블레이드(7)도 본 발명에서와 같이 직4각형이 아닌 다른 형태로 제조하여도 무방한데 이 역시 최대위치로 이동하였을 때 충분한 제동력을 얻을 수 있는 형태라면 어떠한 형태로 변경하여 사용해도 무방하다.On the other hand, the shape and size of the rotating body (5) in consideration of the viscosity of the fluid filled in the housing 4 to have the same rotational speed as the drive shaft (1) during the idle operation, if such conditions are satisfied the present invention As in the present invention, it may be manufactured in a different form instead of a disc shape, and the blade 7 may also be manufactured in a shape other than a rectangular shape as in the present invention, which also has sufficient braking force when moved to the maximum position. If you can obtain a form that can be changed to use any form.
이상 설명한 바와 같이 본 발명에 따르면, 차량의 구동축에 유체의 저항력에 의해 점진적 또는 순간적으로 제동력을 얻도록 구성된 보조감속장치를 부가설치함으로써 제동력 향상과 함께 승차감 향상에도 도움을 주도록 되어 있다.As described above, according to the present invention, an auxiliary deceleration device configured to obtain a braking force gradually or instantaneously by the resistance of the fluid is provided on the drive shaft of the vehicle to help improve the braking force and the ride comfort.
