Description

차량용 보조바퀴Vehicle auxiliary wheel
본 발명은 차량용 보조바퀴에 관한 것으로, 보다 상세하게는 트랙터 등과 같은 차량의 바퀴에 장착되고 사용자의 조작을 통해 접철 가능한 보조날개가 구비되어 논이나 진흙밭과 같은 연약지반에서 보조날개가 펼쳐진 상태로 원활한 작업이 가능하도록 하고, 일반 주행시에는 보조날개가 접힌 상태로 신속하게 이동할 수 있는 차량용 보조바퀴에 관한 것이다.The present invention relates to an auxiliary wheel for a vehicle, and more particularly, is provided on a wheel of a vehicle such as a tractor and is provided with a collapsible auxiliary wing through a user's operation, so that the auxiliary wing is unfolded in a soft ground such as a paddy field or a muddy field. To enable a smooth operation, and in the general driving relates to a vehicle auxiliary wheel that can move quickly in a state in which the auxiliary wings folded.
일반적으로 트랙터는 견인력을 이용하여 각종 작업을 수행하는 차량으로서, 주로 농업용이나 건설용으로 사용하고 있다.In general, a tractor is a vehicle that performs various tasks using a traction force, and is mainly used for agriculture or construction.
트랙터의 구조는 기본적으로는 일반 자동차와 같으나 강력한 엔진을 장착하고 있어 견인력이 좋고 튼튼하다.The structure of the tractor is basically the same as that of a general car, but with a powerful engine, the traction is good and strong.
특히 트랙터는 농경용으로 발달하였으며, 오늘날에도 경작(耕作)용의 가래ㅇ쟁기ㅇ써레ㅇ수확기 등을 견인하는 농작업에 필수적인 장비이다.Tractors, in particular, have been developed for farming and are still essential equipment for farming towing sputum plows, harrow harvesters, and so on.
이와 같은 트랙터는 그 용도상 단단한 지반보다는 물이 많은 논이나 진흙밭과 같은 연약지반에서 작업하는 경우가 많다.Such tractors often work on soft grounds such as paddy fields or mud fields, rather than hard ground for their use.
이 경우에 트랙터의 중량으로 인하여 트랙터의 바퀴가 흙속에 약간만 빠져도 진행하는데 많은 동력이 소모되며, 경우에 따라서는 바퀴만 공회전되면서 지면을 손상시키기 때문에 괭이나 삽 등으로 뒤처리를 해야 하는 불편함이 있다.In this case, due to the weight of the tractor, a small amount of power is consumed to proceed even if the wheel of the tractor falls slightly in the soil, and in some cases, the wheels are idled, which damages the ground. .
이러한 점을 해소하기 위하여 트랙터의 바퀴에 톱니가 부착된 보조바퀴를 추가로 설치하여 작업면의 조건에 관계없이 트랙터가 진행하는데 지장이 없도록 한 기술이 실용신안공보 제20-1995-0010401호(1995.12.13. 공고) 및 실용신안공보 제20-1996-0005248호(1996.06.24. 공고) 등에 개시되어 있다.In order to solve this problem, the technology that installed the auxiliary wheel with the toothed wheel on the tractor wheel to prevent the tractor from progressing regardless of the working surface condition is disclosed in Utility Model Publication No. 20-1995-0010401 (1995.12 13.13) and Utility Model Publication No. 20-1996-0005248 (June 24, 1996).
그러나 상기와 같은 종래기술의 트랙터용 보조바퀴에 의해서도 큰 중량의 트랙터가 물논이나 진흙에 빠져 진행이 되지않는 문제점이 여전히 발생하고 있으며, 물논이나 진흙과 같은 연약지반에서 트랙터의 접지력을 향상하도록 종래기술 각각에 구성된 견인판과 미끄럼방지판을 설치하거나 펼치는 작업이 핀 결합 방식으로의 수작업으로 이루어지기 때문에 작업자가 일일이 조절하여야 하는 등 그 작동법이 매우 번거럽고 불편한 문제점이 있었다.However, there is still a problem that a tractor of a large weight does not proceed by falling into paddy fields or mud even by the auxiliary wheel for tractors of the prior art as described above, and to improve the traction of the tractor in a soft ground such as paddy fields or mud. Since the work to install or unfold the traction plate and the non-slip plate configured in each is made by the manual operation of the pin coupling method, the operation method has to be very cumbersome and inconvenient, such as the operator has to adjust one by one.
이에, 등록실용신안공보 제20-0387157호(2005.06.17. 공고) "트랙터용 보조바퀴"에서는 트랙터의 바퀴에 체결되는 체결부재를 통해 트랙터가 연약 지반을 통과하도록 U자 형상의 수용부가 형성된 복수개의 날개가 연약지반에서 접촉면적을 증가하도록 하는 기술이 개시되어 있다.Accordingly, the Utility Model Registration No. 20-0387157 (2005.06.17. Announcement) In the "tractor wheels for tractor" a plurality of U-shaped receiving portion is formed so that the tractor passes through the soft ground through the fastening member fastened to the wheel of the tractor A technique is disclosed in which dog wings increase the contact area in soft ground.
하지만, 상기와 같은 종래의 "트랙터용 보조바퀴"는 착탈 가능한 구조이긴 하나, 트랙터의 바퀴 외측에서 트랙터 바퀴의 외경과 비슷한 크기로 돌출되게 장착되어 있기 때문에 연약지반 이외의 작업이나 도로주행 시에는 보조바퀴를 해체하여야 하는 번거로움과 불편함이 있었으며, 이를 해소하기 위해 날개 등의 크기를 작게 만든 경우 전자의 종래기술들과 같이 연약 지반에서의 접지력이 떨어지게 되는 문제점이 발생될 수 있는 것이었다.However, the conventional "tractor wheel for tractor" is a detachable structure, but because it is mounted to protrude to a size similar to the outer diameter of the tractor wheel from the outside of the wheel of the tractor assists when working or driving on roads other than soft ground There was a hassle and inconvenience of dismantling the wheels, and when the size of the wing and the like were made small to solve the problem, the problem that the grounding force in the soft ground fell as in the prior arts of the former could occur.
