Description

산업차량용 디스크브레이크 안전장치Disc brake safety device for industrial vehicle

본 고안은 지게차 등과 같은 산업차량의 디스크 브레이크에서 리턴스프링이 없이 동작되는 시스템에서 플레이트나 디스크의 과대 마모시 발생되는 피스톤의 과대 리턴으로 브레이킹이 되지 않아 안전사고가 발생되는 것을 미연에 방지하기 위한 안전장치에 관한 것이다.The present invention is designed to prevent safety accidents from occurring due to excessive braking of pistons caused by excessive wear of a plate or disc in a system operated without a return spring in a disc brake of an industrial vehicle such as a forklift. Relates to a device.

종래 일반적으로 산업차량의 디스크브레이크는 제 1 도에서와 같이 회전축(100)을 따라 함께 회전되는 다수개의 디스크(10)와, 이 디스크(10) 사이 사이에 개재되는 고리상태의 플레이트(20)로 구성되어 피스톤(30)의 로딩으로 상기 디스크(10)와 플레이트(20)가 마찰 협압되어 브레이킹을 이루었다.Conventionally, a disc brake of an industrial vehicle generally includes a plurality of discs 10 rotated together along a rotating shaft 100 and a ring-shaped plate 20 interposed between the discs 10, as shown in FIG. The disk 10 and the plate 20 are frictionally pinched by the loading of the piston 30 to achieve braking.

따라서 오랜사용에 따라 디스크 및 플레이트가 마모되고 피스톤(30)의 시일(31)이 노파되는 이유로, 브레이크 스트로크가 상대적으로 길어지게 되어 과대마모의 경우 브레이킹이 되지 않아 안전사고가 발생될 가능성이 있는 문제점이 있다.Therefore, as the disk and plate are worn and the seal 31 of the piston 30 is old due to prolonged use, the brake stroke becomes relatively long, and in the case of excessive abrasion, there is a possibility that a safety accident may occur because of the breaking. There is this.

또, 상기 마모의 이유로 브레이킹 원심력에 의해 피스톤이 뒤로 밀려나서 브레이킹이 듣지 않는다.In addition, the piston is pushed back by the braking centrifugal force because of the wear, and the braking is not heard.

따라서, 본 고안은 이상과 같은 문제점을 해결하기 위해 창안된 것으로, 본 고안의 목적은 브레이크의 디스크나 플레이트의 과대마모 등의 이유로 브레이킹시 원심력을 받아 피스톤이 과대리턴되거나 브레이크작용시 피스톤이 과다하게 전진될 경우에 이를 운전자에게 알려주어 조치를 취할 수 있게 함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to receive excessive centrifugal force during braking due to excessive wear of the disc or plate of the brake, and to excessively return the piston or excessively the piston when the brake is applied. The objective is to inform the driver when it is moving forward so that he can take action.

상기 목적을 달성하기 위해 본 고안은 피스톤의 적정 스트로크범위의 로드 전후로 볼홈을 형성하고 상기 볼홈 사이에 위치세팅되는 볼스위치를 디스크하우징에 설치하여서 구성된다.In order to achieve the above object, the present invention is formed by forming a ball groove before and after the rod in the appropriate stroke range of the piston and installing a ball switch positioned between the ball grooves in the disc housing.

물론 상기 볼스위치는 차량의 배터리전원을 이용 운전석 등에 설치된 별도 알람 또는 경고등으로 표시해 줄 수 있도록 한다.Of course, the ball switch can be displayed as a separate alarm or warning light installed in the driver's seat using the battery power of the vehicle.

이하에서 본 고안을 바람직한 실시예를 첨부된 도면에 의해 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the preferred embodiments as follows.

본 고안의 설명중 종래와 동일 또는 동등한 부분은 같은 부호로 표기하여 설명하기로 한다.In the description of the present invention, the same or equivalent parts as in the prior art will be described with the same reference signs.

회전축(100)을 따라 함께 회전되는 다수개의 디스크(10)와 이 디스크(10) 사이 사이에 개재되는 고정플레이트(20)로 구비되어 유압작동으로 로딩되는 피스톤(30)의 전진스트로크로 브레이킹되는 산업차량용 디스크브레이크에 있어서, 제 2 도에서와 같이 피스톤(30)의 적정스트로크범위의 로드(40)전후로 볼홈(41)을 형성하고, 상기 볼홈(41) 사이에 위치세팅되는 볼(51)을 가지는 볼스위치(50)를 디스크브레이크 하우징(60)에 설치해서 이루어진 것으로, 상기 볼스위치(50)는 배터리전원을 이용하여 운전석 등에 설치된 알람 또는 경고등으로 표시되게 한다. 이때 상기 볼홈(41)은 피스톤(30)의 로드(40)는 둘레에 걸치게 형성될 것이다.Industry which is provided with a plurality of disks 10 rotated together along the rotating shaft 100 and a fixed plate 20 interposed between the disks 10 and braked by the forward stroke of the piston 30 loaded by hydraulic operation. In the vehicle disc brake, as shown in FIG. 2, the ball groove 41 is formed before and after the rod 40 of the appropriate stroke range of the piston 30, and has the ball 51 positioned between the ball grooves 41. The ball switch 50 is installed by the disc brake housing 60, and the ball switch 50 is displayed by an alarm or a warning lamp installed in a driver's seat using battery power. At this time, the ball groove 41 will be formed so that the rod 40 of the piston 30 is circumferentially.

이상과 같이 구성된 본 고안의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

브레이크 페달을 작동하면 마스크 실린더에 의해 답력이 유압으로 바뀌어 디스크하우징(60)의 유로를 통해 브레이크의 피스톤(30)을 밀어주게되어 그 작용력이 브레이크플레이트(20)를 밀고, 이때 회전하고 있는 브레이크디스크(10)를 서로의 마찰력에 의해 잡아 차량을 정지하게 한다.When the brake pedal is operated, the turning force is changed to hydraulic pressure by the mask cylinder, which pushes the piston 30 of the brake through the flow path of the disc housing 60, and the action force pushes the brake plate 20, and the rotating brake disc is rotated at this time. Hold 10 by the frictional force of each other to stop the vehicle.

이때 과대마모나 피스톤(30)의 과대리턴으로 인해 스트로크가 길어지게 될 때 볼스위치(50)에 있는 볼(51)이 피스톤(30)의 로드(40)에 가공된 볼홈(41)에 들어가게 되어 볼스위치(50)에 연결된 경고장치를 작동하게 되므로 사전에 문제를 알게되어 차량 담당자는 정비를하여 안전사고를 미연에 방지케 할 수 있는 것이다. 이때 볼스위치(50)의 볼(51)이 로드(40)의 전방볼홈(41)에 안착되는 것은 디스크(10) 및 플레이크(20)의 마모를 직접 감지하는 작용을 이루고, 상기 볼스위치(50)의 볼(51)이 로드(40)의 후방 볼홈(41)에 안착되는 것은 피스톤(30)의 시일(31)마모 등을 이유로 디스크브레이크의 브레이킹 원심에 의해 피스톤(30)이 과대하게 후진됨을 감지하는 작용을 이루는 것이다.At this time, when the stroke becomes long due to excessive wear or excessive return of the piston 30, the ball 51 in the ball switch 50 enters the ball groove 41 processed in the rod 40 of the piston 30. Since the warning device is connected to the ball switch 50 is operated to know the problem in advance, the vehicle personnel will be able to prevent the safety accident in advance by maintenance. At this time, the ball 51 of the ball switch 50 is seated in the front ball groove 41 of the rod 40 serves to directly detect the wear of the disk 10 and the flake 20, the ball switch 50 Of the ball 51 of the rod 40 in the rear ball groove 41 of the rod 40 indicates that the piston 30 is excessively reversed by the disc brake braking centrifugal due to the wear of the seal 31 of the piston 30. It is to sense.

이상과 같이 구성되고 작용되는 본 고안은 산업차량의 디스크브레이크에서 브레이크작동을 위한 피스톤의 적정 스트로크를 벗어날 경우의 마모 및 이상을 운전자에게 알려 이의 조치를 취하게하여 그로인한 안전사고를 미연에 방지시킬 수 있는 효과가 있는 것이다.The present invention, which is constructed and operated as described above, informs the driver of wear and abnormality in the case of deviation from the proper stroke of the piston for brake operation in the disc brake of an industrial vehicle, so that the driver can take action to prevent such a safety accident. It can be effective.
