Description

트레일러 적재함용 보조바퀴 승강장치{Auxiliary wheel lifting device for trailer loader}Auxiliary wheel lifting device for trailer loader

본 발명은 트레일러 적재함의 하중을 분산하기 위하여 사용하는 보조바퀴를 승강하기 위한 장치에 관한 것으로, 더욱 상세하게는 스크루 방식의 전동 잭(jack)을 이용하여 바퀴축 및 보조바퀴를 상하로 편리하게 이동할 수 있도록 구성한 트레일러 적재함용 보조바퀴 승강장치에 관한 것이다.The present invention relates to a device for elevating an auxiliary wheel used to distribute the load of a trailer loading box, and more particularly, to conveniently move the wheel axle and auxiliary wheel up and down using a screw-type electric jack. It relates to an auxiliary wheel hoisting device for a trailer loading box configured to be able to

일반적으로 트레일러 등 화물차량은 구동바퀴를 갖는 트랙터에 착탈 또는 일체로 장착되는 적재함의 화물 적재 하중을 고르게 분배하기 위해 차량 뒷부분의 적재함(적재 차체)이 두 개의 피동바퀴축으로 구성되어 있다.In general, a cargo vehicle such as a trailer consists of two driven wheel axles in a loading box (loading body) at the rear of the vehicle to evenly distribute the cargo load of a loading box that is detachably or integrally mounted on a tractor having driving wheels.

그러나 공차 주행시에도 이러한 두 개의 피동바퀴축을 모두 사용함에 따라 불필요한 구름저항, 마찰저항 등이 발생하게 되어 피동바퀴의 마모 및 차량의 연비저하 등의 문제점과 승차감을 저하로 운전자의 피로감을 높이는 문제점이 있었다.However, as both of these driven wheel axles are used during empty driving, unnecessary rolling resistance and frictional resistance are generated. .

그 결과, 공차 주행시 피동바퀴축 중 하나의 피동바퀴축의 위치를 상향 이동하여 한 쌍의 피동바퀴가 구동하지 않도록 상승시키는 방식이 아니라 별도의 보조 피동바퀴축 및 보조 피동바퀴 등의 기계적인 장치설비가 추가적으로 더 구비되는 리프팅 장치들이 제안되었다.As a result, it is not a method of raising the position of one of the driven wheel shafts upward so that the pair of driven wheels do not drive, but a separate auxiliary driven wheel shaft and a mechanical device such as an auxiliary driven wheel. In addition, lifting devices that are further provided have been proposed.

그러나 추가 장착 비용이 많이 소요되며, 다른 한 쌍의 피동바퀴로 주행됨에 따라 주행되는 한 쌍의 피동바퀴에 적재함의 하중이 집중되어 내구성 및 승차감에 있어서 별다른 효과를 나타내지 못하는 문제점이 있었다.However, additional installation cost is high, and the load of the loading box is concentrated on the driven pair of driven wheels as it is driven with the other pair of driven wheels, so there is a problem in that durability and ride comfort are not particularly effective.

이러한 문제점을 해결하기 위하여 등록특허공보 제10-0762970호(이하, '선행기술'이라 함)에서는 별도의 추가 바퀴축을 설치하지 않고, 기존의 화물차량 피동바퀴축에 간단한 구조의 제1 공기스프링을 장착하여 공차 주행시에 용이하게 한 쌍의 피동바퀴를 노면으로부터 이격되도록 하는 간단한 장착 구조로 상승된 피동바퀴의 마모를 줄여 연비 효율을 높이면서도 적재 하중과 주행중 노면에서의 충격이나 진동을 용이하게 흡수하여 주행 승차감을 향상시킬 수 있으며, 전후 피동바퀴축에 각각 공기압식 공기스프링을 설치하여 공차시 차량의 화물적재함의 두 쌍의 피동바퀴 중 한 쌍의 피동바퀴를 상승시켜 타이어의 마모 및 연비를 줄일 수 있도록 하면서도 공차 주행시 한 쌍의 피동바퀴만으로 주행되어도 노면에서의 충격 및 진동을 추가로 감쇠하여 주행 승차감이 향상된 구조를 가진 화물차량의 피동바퀴축 승강장치를 제안하였다. In order to solve this problem, in Patent Publication No. 10-0762970 (hereinafter referred to as 'prior art'), a first air spring having a simple structure is installed on the driven wheel shaft of an existing freight vehicle without installing a separate additional wheel shaft. It has a simple mounting structure that allows a pair of driven wheels to be easily separated from the road surface during tolerance driving by reducing wear of the raised driven wheels to increase fuel efficiency while easily absorbing shocks or vibrations from the load and the road surface while driving. Driving comfort can be improved, and by installing pneumatic air springs on the front and rear driven wheel axles, one of the two pairs of driven wheels of the vehicle’s cargo box is raised when empty, thereby reducing tire wear and fuel economy. We propose a lifting device for a driven wheel axle of a freight vehicle that has a structure that improves driving comfort by additionally attenuating shock and vibration on the road surface even when driving with only a pair of driven wheels during empty driving.

그러나 위 선행기술의 피동바퀴축 승강장치는 제1 및 제2 공기스프링과, 다수의 전방 및 후방 판스프링 등의 부품이 복잡한 결합구조에 의해 설치되어 있기 때문에 조립비용이 상승하게 되고, 동작과정이 단순하지 못하여 비효율적이며, 유지보수에 많은 시간 및 비용이 소모되는 문제점이 있다.However, in the driven wheel shaft elevating device of the prior art, the assembly cost is increased because the first and second air springs and parts such as a plurality of front and rear leaf springs are installed by a complicated coupling structure, and the operation process is simple. It is inefficient because it cannot be done, and there is a problem in that a lot of time and money are consumed for maintenance.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 스크루 방식의 전동 잭을 이용하여 단순한 구성 및 결합구조에 의해 보조바퀴를 승강할 수 있도록 개선한 트레일러 적재함용 보조바퀴 승강장치를 제공함에 그 목적이 있다.The present invention is to solve the above problems, and it is an object of the present invention to provide an auxiliary wheel elevating device for a trailer loading box, which is improved so that the auxiliary wheel can be raised and lowered by a simple configuration and a coupling structure using a screw type electric jack. .
