PROBLEM TO BE SOLVED: To provide an axle weight distribution device for a rear wheel two-axle vehicle enabling axle weight distribution with a simple device configuration at an economic cost, and thereby to make it possible to ensure good travelling performance without causing a hike in the cost.SOLUTION: An axle weight distribution device for a rear wheel two-axle vehicle is provided, including: a rear wheel axle of a first axle being a drive shaft suspended in a leaf suspension manner from a frame; and a rear wheel axle of a second axle being a driven shaft suspended in an air suspension manner from the frame. In the middle of a route leading compressed air 25 decompressed to a constant pressure from an air tank 23 via a pressure reduction valve 24 to each air spring 22 of the second axle, a quick release valve 27 is provided for releasing the pressure on the air spring 22 side, the quick release valve 27 being opened when the pressure on the pressure reduction valve 24 side is higher than the pressure on the air spring 22 side, the quick release valve 27 being closed when the pressure is lower.SELECTED DRAWING: Figure 3
【課題】簡易な装置構成で安価に実施可能な後輪二軸車両の軸重配分装置を提供することによって、コストの高騰を招くことなく良好な走行性能を確保し得るようにする。【解決手段】一軸目の後輪軸をリーフサスペンション形式でフレームに懸架された駆動軸とし且つ二軸目の後輪軸をエアサスペンション形式でフレームに懸架された従動軸とした後輪二軸車両の軸重配分装置に関し、エアタンク23から減圧バルブ24を介し一定圧に減圧した圧縮エア25を二軸目の各エアスプリング22へ導く系路の途中に、減圧バルブ24側の圧力がエアスプリング22側の圧力より高い時に開通し且つ低い時には不通となってエアスプリング22側の圧力を開放するクイックリリースバルブ27を備えた。【選択図】図3
