본 발명은 건설용 장비인 중기의 개량된 스티어링 드라이브 액슬의 제동장치에 관한 것으로, 보다 상세하게는 차축케이스 내부에 디스크 제동장치를 설치하여 냉각유 공급을 원활히 하는 구조에 관한 것이다.The present invention relates to a braking device for an improved steering drive axle of heavy equipment, which is construction equipment, and more particularly, to a structure in which a disk braking device is installed inside an axle case to facilitate supply of cooling oil.
종래의 스티어링 드라이브 액슬은 제3도에 도시한 바와 같이, 입력축(31)으로부터 동력이 입력되면 베벨기어(32)에서 감속이 되고 액슬샤프트(21) 및 유니버셜 조인트(23)를 거쳐 유성기어에서 다시 감속되어 허브(26)에 부착된 바퀴에 전달된다.As shown in FIG. 3, the conventional steering drive axle is decelerated in the bevel gear 32 when power is input from the input shaft 31, and then again in the planetary gear via the axle shaft 21 and the universal joint 23. It is decelerated and transmitted to the wheels attached to the hub 26.
이때, 허브(26)내에 설치된 습식제동장치가 제동을 할 수 있는데, 허브케이스(26) 내부는 여러 가지 장치가 내장되므로 공간이 협소하여 오일공급이 충분치 못하여, 이에 따라 반복되는 제동장치의 작동시 허브케이스(26) 내부의 온도가 급격히 상승되어 브레이크 장치뿐만 아니라 주변장치에 까지 열영향을 미치게 되어 내구성 및 제동성능의 손상을 야기시키는 원인이 되었다.At this time, the wet braking device installed in the hub 26 may be braked, but since the hub case 26 has a variety of devices built in, the space is narrow and the oil supply is not sufficient, and thus the repeated braking device is operated. The temperature inside the hub case 26 is rapidly increased, which affects not only the brake device but also the peripheral device, causing damage to durability and braking performance.
또한, 제동장치는, 유압에 의하여 작동되므로 유로(14)가 충분히 오일을 공급할 수 있도록 구성되어야 하나 너클과 링기어로 연결되는 유로는 연결부분의 밀폐를 위해 O-링을 끼우고 있으나 O-링의 손상으로 인해 허브케이스(26)로의 오일누출의 사례도 자주 발생되고, 너클과 링기어의 유로경사도 가공의 어려움을 더해주고 있다.In addition, the braking device is operated by hydraulic pressure so that the flow path 14 must be configured to supply sufficient oil, but the knuckle and the flow path connected to the ring gear have an O-ring for sealing the connection part. Due to the damage of the oil case to the hub case 26 is often generated, the inclination of the knuckle and the ring gear is also adding to the difficulty of processing.
특히, 회전마찰판(17)과 고정판(18)사이에 존재하는 오일이 제동작동시 급격히 배출되므로써 회전마찰판(17)과 고정판(18)이 미끄러지지 않고 밀착되므로써 제동성능을 충분히 발휘하게 되나, 허브(26)내의 협소한 공간으로 인해 오일배출이 원활하지 못하여 제동성능의 저하 및 마찰판(17), (18)의 수명 저하의 원인이 되어왔다.In particular, since the oil present between the rotating friction plate 17 and the fixed plate 18 is rapidly discharged during the braking operation, the rotating friction plate 17 and the fixed plate 18 come into close contact with each other without slipping, so that the hub 26 Due to the narrow space in the cylinder, oil discharge is not smooth, which causes a decrease in braking performance and a decrease in life of the friction plates 17 and 18.
본 발명은 스티어링 드라이브 액슬의 제동장치를 허브내에서 차죽케이스 쪽으로 옮겨서 설치된 구조를 제공하므로서, 상기의 문제점을 해소시킬 뿐만 아니라, 제동장치가 허브케이스 내에 있는 경우에는 조향시 허브케이스가 회전되므로서 오일을 프렉시블 호스로 연결할 수 밖에 없었으나 자축 케이스내에 설치되는 제동장치를 가지는 본 발명에서는 하드 파이프로 고정연결을 할 수 있어서 그 내구성을 보다 향상시킬 수 있도록 할 뿐만 아니라, 회전 마찰판(17)에 복귀력을 제공하는 리턴 스프링장치의 구조도 개선하여 마찰판(17), (18)의 내구성을 향상시키려는 별개의 목적도 함께 가지고 있다.The present invention provides a structure installed by moving the braking device of the steering drive axle to the car case in the hub, and not only solves the above problems, but when the braking device is in the hub case, the hub case is rotated during steering, so that the oil In the present invention having a braking device installed in the magnetic shaft case, but can be fixed connection by a hard pipe not only to improve the durability, but also to the rotating friction plate 17 It also has a separate purpose to improve the durability of the friction plates 17 and 18 by improving the structure of the return spring device that provides the return force.
본 발명의 구조를 도면에 따라 상세히 설명하면 다음과 같다.Referring to the structure of the present invention in detail as follows.
제1도는 본 발명의 구성단면도이고, 제2도는 제1도의 A부 확대단면도이다.1 is a cross-sectional view of the configuration of the present invention, and FIG. 2 is an enlarged cross-sectional view of portion A of FIG.
엔진으로부터 프렌지(5)에 전달되는 동력을 스플라인을 통해 피니언 기어(4)에 전달하면 피니언 기어(4)에 맞물려 양쪽 케이스(1), (2)에 설치된 크라운 기어(3)를 통해 사이드 기어(29)에 연결된 액슬샤프트(21)로 전달되고 액슬샤프트(21)의 한쪽 끝은 유니버셜 죠인트(23)와 스플라인으로 연결되어 선기어(28)로 연결되고 너클(22)에 스플라인으로 고정된 링기어(25)에 의해 플라넷기어(27)를 회전시키면 허브케이스(26)를 회전시키는 공지의 스티어링 드라이브 액슬 구조에 있어서, 상기 액슬 샤프트(21)의 중간에 스플라인 압입된 연결기(19)가 고정되고, 상기 연결기(19)의 외주에 멈춤링(20)으로 연결된 회전마찰판(17)은 조인트 하우징(9)과 케이스(2) 사이에 끼워 맞춰진 제동케이스(10)의 안쪽에서 스플라인으로 연결 설치된 고정판(18)사이에 교대로 설치되고, 상기 제동케이스(10)에 압입된 피스톤(11)은 상기 제동케이스(10)에 나합된 볼트(15)의 본체내에 삽입된 스프링(16)의 끝단에 연결되고, 상기 제동케이스(10) 외부에서 피스톤(11)측으로 니플(13)을 통해 유로(14)가 형성되어 구성된다.When the power transmitted from the engine to the flange 5 is transmitted to the pinion gear 4 via the spline, it is engaged with the pinion gear 4 and is connected to the pinion gear 4 through the crown gear 3 installed in both cases 1 and 2 so that the side gear ( 29 is connected to the axle shaft 21 connected to the axle shaft 21, and one end of the axle shaft 21 is connected to the universal joint 23 by a spline, connected to the sun gear 28 and fixed to the knuckle 22 by a spline. In the known steering drive axle structure in which the planet gear 27 is rotated by 25 to rotate the hub case 26, the spline press-fit connector 19 is fixed in the middle of the axle shaft 21. The rotating friction plate 17 connected to the outer circumference of the connector 19 by the stop ring 20 is connected to the joint housing 9 and the case 2 by a spline at the inside of the braking case 10 fitted with a spline. Alternately installed between the above The piston 11 press-fitted into the braking case 10 is connected to the end of the spring 16 inserted into the body of the bolt 15 screwed to the braking case 10, and the piston outside the braking case 10. The flow path 14 is formed through the nipple 13 to the (11) side, and is comprised.
상기와 같이 구성된 본 발명에서는 니플(13)을 통해 브레이크유가 인입되면 스프링(16)을 볼트(15)의 머리쪽으로 압축하면서 피스톤(11)를 밀어주게 되며 피스톤(11)은 회전마찰판(17)을 고정판(18)측으로 밀어주어 양 마찰판(17), (18) 사이에 존재하던 오일 액슬샤프트(21)와 내부공간측으로 배출하면서 고정판(18)이 멈추게 되며, 이에 따라 멈춤링(20)을 통해 연결기(19)가 액슬샤프트(21)의 회전을 제동하게 된다.In the present invention configured as described above, when the brake oil is introduced through the nipple 13, the spring 16 is pushed to the head of the bolt 15 while pushing the piston 11, and the piston 11 rotates the friction plate 17. The fixed plate 18 is stopped while pushing the fixed plate 18 to discharge the oil axle shaft 21 and the inner space side between the friction plates 17 and 18, thereby stopping the connector 20 through the stop ring 20. 19 brakes the rotation of the axle shaft 21.
브레이크 페달을 높으면 브레이크유의 공급이 중단되므로 스프링(16)이 복원되면서 스프링(16) 끝에 연결된 피스톤(11)을 복원시키게 되며 이에 따라 회전마찰판(17)과 고정판(18)은 이완이 되어 간격이 생기게 되어 이 틈사이에 방출된 오일이 유입되어 마찰력을 상실시키며 액슬샤프트(21)의 제동력을 없애게 된다.When the brake pedal is raised, the supply of the brake oil is stopped, so that the spring 16 is restored and the piston 11 connected to the end of the spring 16 is restored. Accordingly, the rotary friction plate 17 and the fixed plate 18 are relaxed to cause a gap. Thus, the oil discharged between these gaps flows in and loses the frictional force and eliminates the braking force of the axle shaft 21.
본 발명은 브레이크장치를 공간이 협소한 허브케이스(26)내에서 액슬샤프트(21)측으로 옮겨서 충분한 공간을 확보하게 되어 부품의 가공 및 설치가 용이할 뿐만 아니라 브레이크유 공급도 원활하여 반복되는 제동작동에서도 과열을 방지할 수 있으며, 디스크의 복원시스템을 간편하게 구성하여 비용절감 및 조립 정비에 편리함을 함께 가지며, 특히 차축케이스로 인입되는 유로는 유니버설 죠인트를 거치지 않고 직접 연결되므로 연결이 공고하고 밀폐가 용이하여 종래와 같이 누유등의 문제점을 완전히 개선하게 된다.According to the present invention, the brake device is moved to the axle shaft 21 in the hub case 26 having a small space, thereby ensuring sufficient space, thereby facilitating the processing and installation of parts as well as providing a smooth supply of brake oil. Overheating can be prevented and the disk restoring system can be easily configured for convenient cost reduction and assembly maintenance.In particular, the flow path into the axle case is directly connected without going through a universal joint, making the connection secure and easy to seal. As a result, problems such as leakage are completely improved.
