Description

차량의 더블 브레이크 장치Double brake system of vehicle

본 발명은 차량의 제동장치에 쓰이는 것으로 특히 디스크식 브레이크에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake, in particular for use in a braking device of a vehicle.

제동장치는 주행하는 자동차를 감속 또는 정지시킴과 동시에 주차상태를 유지하기 위해 사용하는 중요한 장치이며 일반적으로 마찰력을 이용하여 자동차의 운동 에너지를 열 에너지로 바꾸어 제동작용을 하는 마찰식 브레이크가 널리 사용되고 있다.Braking device is an important device used to maintain a parking state while decelerating or stopping a driving car. In general, a friction type brake that uses a friction force to convert a vehicle's kinetic energy into thermal energy and brakes is widely used. .

그러나 종래 브레이크 장치의 경우 도 3 에 도시한 것과 같이 운전자가 브레이크 페달을 밟을 때 상기 페달과 연결된 마스터 실린더의 유압이 이동하여 캘리퍼(10)의 사이에 결합된 디스크(20)의 양측을 상기 캘리퍼(10)의 일측에 고정 장착되어 디스크와 대향된 피스톤(60)이 디스크(20) 방향으로 밀려나게 되므로 상기 피스톤(60)의 패드(70)는 디스크(20)와 밀착되면서 이에 따른 마찰력에 의해 자동차의 감속이 유도되도록 하고 있다.However, in the case of the conventional brake device, as shown in FIG. 3, when the driver presses the brake pedal, the hydraulic pressure of the master cylinder connected to the pedal is moved so that both sides of the disc 20 coupled between the calipers 10 are connected to the caliper ( 10 is fixed to one side of the piston (60) facing the disk is pushed in the direction of the disk 20, so the pad 70 of the piston 60 is in close contact with the disk 20, the vehicle by the friction force accordingly To decelerate.

따라서 상기와 같은 장치는 단순히 디스크의 일측면에서 받는 마찰력으로만 자동차를 감속시키기에는 디스크에서 받는 부하가 많을 뿐만 아니라 제동거리가 길어지게 되어 교통사고 유발의 원인이 되는 문제점이 지적되고 있다.Therefore, such a device has been pointed out that a problem that causes not only a heavy load on the disk but also a long braking distance to decelerate the vehicle only by the frictional force received from one side of the disk causes a traffic accident.

이에 본 발명은 상기한 문제점을 개선시키기 위하여 디스크의 마찰력을 상승시키므로서 제동력을 향상시키며 사고에 대비한 안전성의 확보에 본 발명의 목적이 있다.Accordingly, the present invention has an object of the present invention to improve the braking force by increasing the frictional force of the disk in order to improve the above problems and to ensure safety against accidents.

상기한 목적을 달성하기 위한 수단으로 본 발명은, 스풀라인에 끼워진 디스크의 일측면에 캘리퍼가 차체에 고정 장착되고 상기 캘리퍼의 유압에 의해 피스톤과 일체로 결합된 패드가 디스크와 마찰이 이루어지도록 구성된 브레이크에 있어서, 스풀라인에 끼워져 좌우 이동이 가능한 한 쌍의 디스크와, 상기 디스크의 사이에 결합되어 좌우 이동하는 디스크를 원위치로 복원시키는 인장 스프링과, 상기 인장 스프링과 함께 디스크의 사이에 끼워지며 차체에 고정장착되어 디스크의 내측면에 마찰력을 일으키도록 피스톤과 패드를 결합한 보조 실린더와,의 구성을 특징으로 한다.As a means for achieving the above object, the present invention, the caliper is fixedly mounted to the vehicle body on one side of the disk fitted in the spool line and the pad is integrally coupled with the piston by the hydraulic pressure of the caliper is configured to friction with the disk In the brake, a pair of disks inserted into the spool line and movable left and right, a tension spring for restoring the disk coupled to the left and right to move to the original position, and is inserted between the disk together with the tension spring And an auxiliary cylinder fixedly mounted to the auxiliary cylinder, the piston and the pad being coupled to generate a frictional force on the inner surface of the disk.

이를 첨부한 실시예 도면을 참조하여 보다 상세하게 설명하면, 도 1 은 본 발명의 구성을 나타낸 정면도이고 도 2 는 A부 상세도이다. 부호 1은 캘리퍼이고 부호 2는 디스크이다.Referring to this in more detail with reference to the accompanying drawings, Figure 1 is a front view showing the configuration of the present invention and Figure 2 is a detailed view of the portion A. 1 is a caliper and 2 is a disk.

변속기와 연결된 스풀라인(5)에는 한 쌍의 디스크(2)를 끼우고, 상기 디스크(2)는 스풀라인(5)의 축에서 일정간격 좌우 이동이 가능하도록 결합한다. 그리고 상기 디스크(2)의 사이에 결합되어 디스크(2)와 함께 회전하며 좌우 이동하는 디스크(2)를 초기위치로 복원시키는 인장 스프링(4)을 다수개 고정 결합한다.A pair of disks (2) is fitted to the spool line (5) connected to the transmission, and the disks (2) are coupled so as to be able to move at regular intervals on the axis of the spool line (5). A plurality of tension springs 4 are coupled between the disks 2 to fix the disks 2 that rotate with the disks 2 and restore the disks 2 to the initial positions.

또한 상기 디스크(2)의 일측에 위치하며 차체에 고정 장착된 캘리퍼(1)의 피스톤(6)이 밀어내어 패드(7)와 디스크(2)가 마찰을 일으키는 면과 반대 방향에서 마찰력을 일으키도록하기 위하여 피스톤(6')과 패드(7')를 내장한 다수개의 보조 실린더(3)를 차체에 고정시킨다.In addition, the piston (6) of the caliper (1) fixed to the vehicle body located on one side of the disk (2) is pushed out so that the pad (7) and the disk (2) generate frictional force in the opposite direction to the frictional surface. To this end, a plurality of auxiliary cylinders 3 incorporating a piston 6 'and a pad 7' are fixed to the vehicle body.

상기와 같이 구성된 본 발명은 운전자가 자동차의 제동을 위해 브레이크 페달을 밟으면 파스칼의 원리에 의해 마스터 실린더의 오일은 캘리퍼(1)와 보조 실린더(3)로 동시에 공급 되어진다.According to the present invention configured as described above, when the driver presses the brake pedal for braking of the vehicle, oil of the master cylinder is simultaneously supplied to the caliper 1 and the auxiliary cylinder 3 according to Pascal's principle.

차체에 고정 장착된 상기 캘리퍼(1)로 오일 공급 통로를 통하여 전해진 오일(8)은 피스톤(6)과 밀착된 패드(7)를 디스크(2)의 외주면에서 내측면으로 밀게 되고, 상기 디스크(2)의 사이에 고정 장착된 보조 실린더(3)에도 오일 공급 통로를 통한 오일(8)이 피스톤(6')과 밀착 고정된 패드(7')를 디스크(2)의 내측면에서 외측면으로 밀게 되므로 디스크(2)의 내측면과 외측면에서 동시에 패드(7,7')와 디스크(2)는 마찰력이 발생하므로 제동력이 향상되는 것이다.The oil 8 transmitted through the oil supply passage to the caliper 1 fixedly mounted to the vehicle body pushes the pad 7 in close contact with the piston 6 from the outer circumferential surface of the disk 2 to the inner surface. In the auxiliary cylinder 3, which is fixedly mounted between 2), the oil 8 through the oil supply passage moves the pad 6 'tightly fixed to the piston 6' from the inner side to the outer side of the disk 2; Since the pads 7 and 7 'and the disk 2 simultaneously generate frictional forces on the inner and outer surfaces of the disk 2, the braking force is improved.

이때 상기 디스크(2)의 내측에 고정되어 양쪽의 디스크(2) 사이가 벌어지지 않도록 당기며 지지되는 인장 스프링(4)을 중심으로 디스크(2)는 캘리퍼(1)와 보조 실린더(3)의 유압에 의해 스풀라인(5)의 축에서 일정간격 좌우로 이동하게 된다.At this time, the disk (2) is fixed to the inside of the disk (2) is pulled and supported so as not to open between the disk (2) of the disk (2) of the caliper (1) and the auxiliary cylinder (3) The hydraulic pressure is moved left and right at a predetermined interval from the axis of the spool line (5).

또한 브레이크 페달을 떼었을때에는 캘리퍼(1)와 보조 실린더(3)로 전해지던 유압에 의한 마찰력이 감소하므로 디스크(2)와 패드(7,7')는 분리됨과 동시에 양쪽 디스크(2)는 인장 스프링(4)의 탄성에 의해 당겨지게 되고 브레이크 제동상태에서 해제되어 초기위치로 되돌아 가게 된는 것이다.In addition, when the brake pedal is released, the frictional force caused by the hydraulic pressure transmitted to the caliper 1 and the auxiliary cylinder 3 is reduced, so that the disc 2 and the pads 7 and 7 'are separated and both discs 2 are tensioned. It is pulled by the elasticity of the spring 4 and released in the brake braking state to return to the initial position.

그러므로 상기와 같은 본 발명은 다수개의 디스크를 설치하여 보다 많은 면적에서 발생하는 마찰력을 상승시키므로 제동력이 상승되며, 안전성이 확보되어 사고예방에 효과가 있는 유용한 발명인 것이다.Therefore, the present invention as described above is a useful invention to increase the frictional force generated in a larger area by installing a plurality of disks to increase the braking force, to ensure safety and to prevent accidents.
