Description
본 발명은 자동차의 드럼 브레이크 제동 균일 구조에 관한 것이다.The present invention relates to a drum brake braking uniform structure of a motor vehicle.
일반적으로, 자동차의 브레이크는 푸트 브레이크와 주차 브레이크로 구분되는 바, 상기한 푸트 브레이크는 상용차의 경우 공압을 사용하여 4륜에 장착된 디스크 브레이크 또는 드럼 브레이크를 제어함으로써 자동차의 제동력을 발생시키게 되는 것이다.In general, a brake of a vehicle is classified into a foot brake and a parking brake. In the case of a commercial vehicle, the foot brake generates a braking force of the vehicle by controlling a disc brake or a drum brake mounted on four wheels using pneumatic pressure. .
즉 도 2에 도시된 바와 같이 브레이크 페달(50)이 설치된 브레이크 밸브(51)와, 상기한 브레이크 밸브(51)에 연결되어 있는 전, 후륜 에어 탱크(52,53)와, 상기한 전, 후륜 에어 탱크(52,53)에 드라이어(54)를 개재한 상태로 연결된 컴프레서(55)와 상기한 브레이크 밸브(51)에 퀼 릴리즈 밸브(56) 및 릴레이 밸브(57)를 개재한 상태로 연결된 브레이크(58)로 구성되어 있다.That is, as shown in FIG. 2, the brake valve 51 provided with the brake pedal 50, the front and rear air tanks 52 and 53 connected to the brake valve 51, and the front and rear wheels described above. The compressor 55 connected to the air tanks 52 and 53 via the dryer 54 and the brake connected to the brake valve 51 via the quill release valve 56 and the relay valve 57. It consists of 58.
브레이크(58)에는 드럼 브레이크가 많이 사용되는 바, 이는 도 3에 도시된 바와 같이 액슬축(미 도시)에 결합되어 회전되는 드럼(59)과, 상기한 드럼(59)의 내부에 앵커 핀(60)으로 설치되어 있는 슈우(61)와, 상기한 슈우(61)의 작동력을 발생시키도록 설치된 휠 실린더(62)로 구성되어 있다.Many brakes are used for the brakes 58, which are coupled to an axle shaft (not shown), as shown in FIG. 3, and the drum 59 rotates, and an anchor pin (inside the drum 59). And a wheel cylinder 62 provided to generate the operating force of the shoe 61 described above.
즉, 상기한 드럼(59)이 회전되면서 슈우(61)에 부착되어 있는 라이닝(미도시)과 브레이킹 동작을 수행하게 되는 바, 상기한 제동력은 드럼(59)이 반시계 방향으로 회전할 때 좌측의 슈우(61')가 리딩 슈가 되어 제동력이 보다 크게 발생되고, 우측의 슈우(61)는 트레일링 슈우가 되어 제동력이 매우 작게 되는 것이다.That is, the drum 59 is rotated to perform a braking operation with a lining (not shown) attached to the shoe 61. The braking force is left when the drum 59 rotates counterclockwise. The shoe 61 'becomes a leading shoe, and a greater braking force is generated, and the shoe 61 on the right becomes a trailing shoe, and the braking force becomes very small.
그러나, 상기한 바와 같이 드럼 브레이크의 제동 시 리딩 슈우와 트레일링 슈우로 분리되고, 양측의 제동력이 불균일하게 됨으로써 제동력이 저하되는 문제점이 있다.However, as described above, the braking force of the drum brake is separated into the leading shoe and the trailing shoe, and the braking force of both sides is uneven, so that the braking force is deteriorated.
따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 드럼 브레이크의 브레이킹 시 제동력을 균일하게 유지할 수 있는 드럼 브레이크의 제동력 균일구조를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, and to provide a uniform braking force structure of the drum brake that can maintain the braking force uniformly during braking of the drum brake.
상기한 목적을 실현하기 위하여 본 발명은 드럼 브레이크에 설치된 휠 실린더에 대칭되도록 보조 휠 실린더가 설치되어 있고, 상기한 휠 실린더와 보조 휠 실린더에 인가되는 공압을 제동력 분포가 균일하도록 제어하는 제어 밸브 및 ECU로 구성함을 특징으로 한다.In order to achieve the above object, the present invention provides a control valve for controlling the pneumatic pressure applied to the wheel cylinder and the auxiliary wheel cylinder so that the auxiliary wheel cylinder is provided symmetrically to the wheel cylinder installed in the drum brake; It is characterized by the configuration of the ECU.

도 1은 본 발명에 따른 드럼 브레이크의 제동력 균일 구조를 도시한 개략도로서, 드럼 브레이크에 설치된 휠 실린더(62)에 대칭되도록 보조 휠 실린더(1)가 설치되어 있고, 상기한 휠 실린더(62)와 보조 휠 실린더(1)에 인가되는 공압을 제동력 분포가 균일하도록 제어하는 제어 밸브(2) 및 ECU(3)로 구성되어 있다.1 is a schematic view showing a uniform braking force structure of a drum brake according to the present invention, in which an auxiliary wheel cylinder 1 is provided to be symmetrical to a wheel cylinder 62 installed in a drum brake, and the wheel cylinder 62 described above. It consists of the control valve 2 and ECU3 which control the pneumatic pressure applied to the auxiliary wheel cylinder 1 so that a braking force distribution may be uniform.
즉, 상기한 ECU(3)와 제어 밸브(2)로 휠 실린더(62)와 보조 휠 실린더(1)의 공압을 제어함으로써 양측의 슈우(61)에서 균일한 제동력이 발생되도록 하는 것이다.That is, by controlling the pneumatic pressure of the wheel cylinder 62 and the auxiliary wheel cylinder 1 with the ECU 3 and the control valve 2, a uniform braking force is generated in the shoe 61 on both sides.
상기한 바와 같은 본 발명의 작용 효과를 설명하면 운전자가 제동을 위해 브레이크 페달(50)을 밟게 되면 브레이크 밸브(51)가 동작되면서 전, 후륜 에어 탱크(52,53)로부터 공압이 브레이크(58)로 공급된다.Referring to the operation and effect of the present invention as described above, when the driver presses the brake pedal 50 for braking, the brake valve 51 is operated while pneumatic pressure from the front and rear air tanks 52 and 53 is applied to the brake 58. Is supplied.
브레이크(58)에 공압이 공급되면 휠 실린더(62)와 보조 휠 실린더(1)가 동작되면서 슈우(61)가 확장됨과 아울러 드럼(59)과의 사이에서 제동력이 발생된다.When pneumatic pressure is supplied to the brake 58, the wheel cylinder 62 and the auxiliary wheel cylinder 1 are operated to expand the shoe 61 and generate a braking force between the drum 59.
즉, 휠 실린더(62)에 공압이 인가되면 슈우(61)가 확장되면서 통상적으로 브레이크가 동작되는 바, 상기한 동작 시 트레일링 슈우(61)에서 제동력이 미약하게 되면 ECU(3)가 밸브(2)를 제어하게 된다.That is, when pneumatic pressure is applied to the wheel cylinder 62, the brake 61 is normally extended while the brake is operated. When the braking force is weak in the trailing shoe 61 during the above operation, the ECU 3 may close the valve ( 2).
여기서, 상기한 ECU(3)는 차속 센서등으로부터 신호를 받아 상기한 밸브(2)를 제어하게 되는 바, 상기한 보조 휠 실린더(62)에 공압을 인가하게 되고, 상기한 공압에 의해 트레일링 슈우(61)에 제동력이 증대됨으로써 양측의 슈우(61',61)로부터 균일한 제동력이 발생된다.Here, the ECU 3 receives a signal from a vehicle speed sensor or the like to control the valve 2, thereby applying air pressure to the auxiliary wheel cylinder 62, and trailing by the air pressure. As the braking force is increased on the shoe 61, uniform braking force is generated from the shoes 61 'and 61 on both sides.
즉, 리딩 슈우(61')와 트레일링 슈우(61)의 제동력이 동일하게 되는 바, 전체적인 제동력이 보다 향상되는 것이다.That is, since the braking force of the leading shoe 61 'and the trailing shoe 61 becomes the same, the overall braking force is improved.
물론, 상기한 밸브(2)를 통한 공압 인가는 리딩 슈우(61')로 보다 적게 인가되고, 트레일링 슈우(61)로 많이 인가됨으로써 동일한 제동력이 발생되도록 하는 것이다.Of course, the pneumatic application through the valve (2) is less applied to the leading shoe (61 '), it is applied a lot to the trailing shoe (61) so that the same braking force is generated.
이상과 같이 본 발명은 리딩 슈우와 트레일링 슈우의 제동력을 균일하게 함으로써 공압 브레이크의 제동력을 향상시킬 수 있는 잇점이 있는 것이다.As mentioned above, this invention has the advantage that the braking force of a pneumatic brake can be improved by making the braking force of a leading shoe and a trailing shoe uniform.
