Abstract

본 발명은 대형차량용 잭장치에 관한것으로서, 대형차량을 링크시스템(20)에 의해 상승,하강 시킬 수 있도록 한 잭장치(1)에 있어서, 상기 잭장치(1)의 베이스(2)에 직경이 작은 기어가 동일축상에 일체로 출설된 기어1, 1A (5) (6)와 기어2, 2A(7) (8)와 기어3, 3A(9) (10)와 기어 4, 4A(11) (12)와 5, 5A(13, 14)를 직경이 큰 기어를 순차적으로 치합시키고, 일축의 기어(5)는 모터(3)로 작동되는 구동 수단과 연결된 직경이 작은 구동기어(4)와 치합시키며, 타측의 직경이 작은기어 5A(14)브라켓(15)의 축(18) (19)에 고정되어 상호치합된 기어6(16)과 기어7(17) 중 기어(6(16)과 치합시키고, 상기 각축(18) (19)에는 상·하강 절첩되는 링크시스템(20)을 설치하며, 링크시스템(20)의 중앙상단에는 받침대(21)가 구비됨에 따라 잭장치의 받침대를 상·하강시키는 링크의 이송을 다수개의 직경이 크고 작은 기어의 구동에 의해 작동되게 하므로서 소형화된 잭장치를 이용하여 최소한의 구동힘으로 무게 하중이 큰 대형 차량을 손쉽고 용이하게 상승, 또는 하강시킬 수 있도록 한 효과가 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jack device for a large vehicle, wherein the jack device (1) allows a large vehicle to be raised and lowered by the link system (20), and the diameter of the jack device (1) is increased. Gears 1, 1A (5) (6) and gears 2, 2A (7) (8) and gears 3, 3A (9) (10) and gears 4 and 4A (11), in which small gears are integrated on the same axis (12) and 5, 5A (13, 14) are sequentially engaged with a large diameter gear, the single-axis gear (5) and the small diameter drive gear (4) connected to the drive means operated by the motor (3) Gears 6 (16) and gears 7 (17) of gears 6 (16) and 7 (17) which are engaged with each other by being fixed to the shafts (18) (19) of the gear (5A) (14) and the bracket (15). And a link system 20 that is folded up and down on each of the shafts 18 and 19, and a pedestal 21 is provided on the center upper portion of the link system 20, so that the pedestal of the jack device is provided. The feed of the descending link And will have the effect to using a jack device miniaturization hameuroseo be operated by the drive of the small gear can be easily and facilitate the weight load is largest heavy vehicles with a minimum of driving power increases, or falling.
