* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 트랙프레임(Track Frame) 2,2' : 브라켓트(Bracket)1: Track Frame 2,2 ': Bracket

3 : 로울러 4 : 트랙3: roller 4: track

5 : 부싱(Bushing)5: Bushing

본 고안은 트랙식 트랙터(Track Tractor)의 언더캐리지(Under carrige)의 하부로울러 축에 유선형의 부싱을 삽입고정하고 부싱에 대응되는 동일한 곡률의 곡면이 브라켓트에 형성되어 주행시 좌,우장애물에 대해 로울러가 좌,우이동없이 회전운동을 하게되어 트랙보정을 하게 되는 장치에 관한 것이다.The present invention fixes the streamlined bushing to the lower roller shaft of the undercarrige of the track tractor and the curved surface of the same curvature corresponding to the bushing is formed on the bracket, so It is related to the device to perform the track correction by the rotary motion without moving left and right.

일반적으로 도자등의 중장비에 있어 로울러 고정장치는 그 고정방법에 따라 고정식, 유압실린더식, 보기시스템(BOGI-System)등이 있는데 이들은 앞뒤의 장애물에 대한 트랙보정을 위한 장치였을뿐 좌우 장애물에 대한 트랙보정은 불가능 하였다.In general, in the heavy equipment such as ceramics, the roller fixing device is fixed, hydraulic cylinder type, BOGI-system, etc. according to the fixing method. Track correction was not possible.

특히, 제1도에 도시한 바와 같이 상기 고정식에 의한 로울러 고정장치는 트랙프레임(1)에 브라켓트(2)(2')를 설치하여 로울러(3)를 장착하였기 때문에 트랙(4)의 저면 일측에 장애물이 돌출되어 있는 경우 트랙이 부분적으로만 장애물에 접지되어 일측의 브라켓트(2) 및 로울러어 접지압이 증가하게 되고 장비의 견인력이 저하되는 문제가 있었다.In particular, as shown in FIG. 1, the fixed roller fixing device is provided with a bracket (2) (2 ') on the track frame (1) so that the roller (3) is mounted to one side of the bottom surface of the track (4). If the obstacle is protruding in the track is only partly grounded to the obstacle to increase the bracket (2) and roller ground pressure of one side, there was a problem that the traction of the equipment is lowered.

또한, 일본공개특허 소58-89474호에 개시된 "로울러 전륜"은 방위 산업용의 각종 전투차량에 장착시켜 주행지면의 요철면부에 대해 주행성을 향상시킬수 있도록 한 것으로, 차량의 본체에 장착되는 축(3)에 구면체(5)가 장착되고, 상기 축(3)에 비틀림자재토록 장착되는 전륜(4)에 구면체(5)와 대응되는 베어링체(6)가 장착되며, 상기 베어링체(6)일측에 이의 마모방지를 위해 주입되는 그리이스, 윤활제등의 누유를 방지하기 위해 시일(7)이 장착되어 탱크등에 사용할 수 있도록 고안되어 있으나, 전륜(4)의 구동부위가 기계적인 구조가 너무 복잡하여 원가가 상승되는 문제점과 축(3)에 형성딘 구면체(5)와 베어링체(6)사이에 발생되는 마모를 감소시키기 위해 정기적으로 그리이스등을 주입해주어야 되는 것이었다.In addition, the "roller front wheel" disclosed in Japanese Patent Laid-Open No. 58-89474 is designed to be mounted on various combat vehicles for the defense industry so as to improve the driving performance with respect to the uneven surface portion of the driving surface. The spherical body 5 is mounted to the spherical body 5, and the bearing body 6 corresponding to the spherical body 5 is mounted on the front wheel 4, which is mounted to the shaft 3 in a torsional manner, and on one side of the bearing body 6. The seal 7 is designed to be used in tanks to prevent leakage of grease, lubricant, etc., which is injected to prevent wear, but the driving part of the front wheel 4 has a mechanical structure so complicated that In order to reduce the wear problem between the spherical body 5 and the bearing body 6 formed on the shaft 3 and the bearing was to be periodically injected with grease.

본 고안은 상기와 같은 문제점을 감안하여 안출된 것으로서 트랙의 저면 좌우일측에 장애물이 돌출되어 있을 경우 로울러가 경사지게 회동하여 트랙이 전반에 걸쳐 지면에 접지되도록하여 접지면적을 증가시켜 접지압을 저하시키고, 장비의 견인력을 증가시키며, 장비의 요동완화로 충격이 감소되어 소음 및 작업자의 피로도를 감소시키는 트랙보정장치를 제공하는데 목적이 있는 것이다.The present invention was devised in view of the above problems, and when an obstacle protrudes from the left and right sides of the bottom of the track, the roller rotates inclined so that the track is grounded throughout the ground, thereby increasing the ground area and lowering the ground pressure. It is an object of the present invention to provide a track compensating device which increases the traction of the equipment and reduces the impact of the equipment by the shaking of the equipment to reduce the noise and the fatigue of the worker.

본 고안의 다른목적은 언더캐리지의 트랙프레임에 대향되는 브라켓트를 설치하고 상기 브라켓트에 로울러를 회전가능토록 설치하되, 상기 로울러는 이의 양단부에 유선형의 부싱을 장착하고 부싱과 대응되는 곡면부가 브라켓트에 형성된것으로 기계적인 구조가 단순화되므로 부품수가 줄어들어 가격을 절감시킬 수 있도록 된 트랙보정장치를 제공하는데 있는 것이다.Another object of the present invention is to install a bracket facing the track frame of the undercarriage and to install the roller to the roller rotatable, the roller is equipped with a streamlined bushing at both ends thereof and the curved portion corresponding to the bushing is formed in the bracket In this way, the mechanical structure is simplified, and thus the number of parts is reduced, thereby providing a track compensator which can reduce the price.

상기 목적을 달성하기 위한 본 고안의 특징은 트랙프레임에 브라켓트를 고정하여 로울러를 지지하는 통상의 언더캐리지에 있어서, 상기 로울러의 양축에 유선형의 부싱을 각각 삽입고정하고 이와 대향되는 브라켓트에 곡면을 형성시킨 구조로 된 것으로서 첨부된 도면에 의거하여 본 고안의 구성을 상세히 설명하면 다음과 같다.A feature of the present invention for achieving the above object is a conventional undercarriage for supporting a roller by fixing a bracket to a track frame, each of which is fixed to insert a streamlined bushing on both axes of the roller and to form a curved surface on the bracket facing the Referring to the configuration of the present invention in detail based on the accompanying drawings as a structure made as follows.

제2도는 트랙식 트랙터의 언더캐리지의 하부로울러에 본 고안이 실시된 상태를 나타낸 단면도로서 트랙프레임(1)에 하부로울러(3)를 회동되게 고정할 수 있는 브라켓트(2)(2')가 형성되고 로울러(3)의 원주면을 따라 회동하는 트랙(4)이 결합된 통상의 언더캐리지에 있어서, 상기 하부로울러(3)의 양축(6)(6')에 유선형의 부싱(5)(5')을 삽입고정하고, 상기 부싱(5)(5')과 대응되는 브라켓트(2)(2')에는 부싱(5)(5')과 동일한 곡률을 가지는 곡면을 형성시켜 하부 로울러(3)가 좌우이동 없이 회전운동만 할 수 있도록 구성시킨 것이다.2 is a cross-sectional view showing a state in which the present invention is carried out on the lower roller of the undercarriage of the tracked tractor, and a bracket (2) (2 ') capable of pivotally fixing the lower roller (3) to the track frame (1) is provided. In a conventional undercarriage formed with a track 4 formed and pivoted along a circumferential surface of the roller 3, a streamlined bushing 5 (2) on both shafts 6, 6 'of the lower roller 3 5 '), and the lower roller 3 is formed by forming a curved surface having the same curvature as the bushings 5 and 5' in the brackets 2 and 2 'corresponding to the bushings 5 and 5'. ) Is configured to only rotate without moving left and right.

본 고안은 전후 장애물에 대한 트랙보정을 할 수 있는 장치가 설치된 언더캐리지, 예를 들어 유압실린더식 또는 겹판스프링식 등이 설치된 장치에 실시를 하면 더욱더 바람직하다.The present invention is even more preferable if the undercarriage, for example, the hydraulic cylinder type or leaf spring type, which is installed with a device that can track correction for front and rear obstacles.

상기와 같은 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as described above are as follows.

제3도에 도시된 바와 같이 운전중 일측트랙의 저면 좌측에 요철이 형성되어 있으면 하부로울러(3)는 로울러 중심을 기준점으로 원운동할 수 있도록 하부로울러 축(6)(6')양측에 부싱(5)(5')이 장착되어 있으므로 하부로울러(3)는 원운동을 하여 장애물에 대한 트랙보정을 한다.As shown in FIG. 3, if unevenness is formed on the bottom left side of one track during operation, the lower roller 3 bushes both sides of the lower roller shaft 6, 6 'so as to be circularly moved from the center of the roller. (5) (5 '), the lower roller (3) performs a circular motion to compensate for obstacles.

즉, 주행시 트랙(4)의 저면 좌,우 어느일측에 돌출물이 있는 경우 돌출물측의 브라케트(2) 및 로울러(3)의 축(6)에 맞은편 브라켓트(2') 및 로울러(3)의 축(6')보다 하중이 쏠리게 되므로 돌출물에 대해 트랙 보정을 하게 되는 것이며, 이때 하부로울러(3)의 양축(6)(6')에 고정된 부싱(5)(5')중 돌출물측의 부싱(5)이 하부로울러(3)의 중심점(0)를 기준점으로 브라켓트(2)의 곡면을 따라 반시계 방향으로 회동됨에 따라 로울러(3)는 돌출물에 의해 경사진 트랙(4)에 대해 수평상태를 유지할 수 있어 트랙프레임(1)의 수직방향의 중심선에서 좌,우 이동없이 원활한 경사회동만 하게되어 돌출물에 대해 트랙보정을 하게 된다.That is, when there is a protrusion on either side of the bottom left or right of the track 4 during traveling, the bracket 2 'and the roller 3 opposite to the bracket 2 on the protrusion side and the shaft 6 of the roller 3 are located. Since the load is more concentrated than the shaft 6 'of the protrusion, the track is compensated for the protrusion. At this time, the protrusion side of the bushings 5, 5' fixed to both shafts 6, 6 'of the lower roller 3 is fixed. As the bushing 5 is rotated counterclockwise along the curved surface of the bracket 2 with respect to the center point 0 of the lower roller 3 as a reference point, the roller 3 is in relation to the track 4 inclined by the projection. Since the horizontal state can be maintained, smooth tilt rotation is performed without moving left and right at the center line in the vertical direction of the track frame 1 so as to compensate for the protrusion.

따라서, 본 고안은 트랙의저면 좌우일측에 장애물이 돌출되어 있을 경우 로울러가 경사지게 회동하여 트랙이 전반에 걸쳐 지면에 접지되도록 하여 접지압을 저하시키고, 장비의 견인력을 증가시키며, 장비의 요동완화로 충격이 감소되어 소음 및 작업자의 피로도를 감소시키며, 하부로울러의 구동부위를 단순화시켜 부품수가 줄어들어 원가절감으로 제품의 가격을 낮출 수가 있는 것이다.Therefore, the present invention, when an obstacle protrudes from the left and right side of the bottom of the track, the roller rotates inclined so that the track is grounded to the ground throughout the ground to reduce the ground pressure, increase the traction of the equipment, impact by loosening the equipment This reduces the noise and fatigue of the operator, and simplifies the drive portion of the lower roller to reduce the number of parts to reduce the price of the product by reducing the cost.
