To provide a mechanical start auxiliary device which can keep a piping length from an air tank to an air spring constant even in different car types.SOLUTION: A mechanical start auxiliary device, in which rear wheels are set as two shafts and the two shafts are suspended from a frame 5 by a trunnion suspension 16 and are applied to a rear wheel two-shaft vehicle with a front shaft of the two shafts as a driving shaft and a rear shaft as a driven shaft, includes an air spring that swells in a direction of lifting up the rear shaft at light loading including vacancy, thereby transfers a shaft load to the front shaft and is kept at a fixed pressure by a pressure-control valve so as to assist start, curves an intermediate part of a trunnion shaft 25 in the trunnion suspension 16 downward, expands an excess space 26 between the intermediate part and the upper frame 5, and arranges an air tank 24 interposed in an air pipe between the pressure-control valve and the air spring in the excess space 26.SELECTED DRAWING: Figure 1
【課題】車型違いにおいてもエアタンクからエアスプリングまでの配管長を一定に保つことが可能な機械式発進補助装置を提供する。【解決手段】後輪を二軸として該二軸をトラニオンサスペンション16によりフレーム5から懸架し且つ前記二軸のうち前軸を駆動軸とし後軸を従動軸とした後輪二軸車両に適用され、空車時を含む軽積載時に前記後軸を持ち上げる方向に膨らむことで軸重を前記前軸に移して発進を補助し得るよう調圧バルブにより一定圧に保持されるエアスプリングを備えた機械式発進補助装置に関し、前記トラニオンサスペンション16におけるトラニオンシャフト25の中間部を下方に湾曲させて該中間部と上方のフレーム5との間の余剰スペース26を拡張し、前記調圧バルブと前記エアスプリングとの間のエア配管に介装されるエアタンク24を前記余剰スペース26に配置する。【選択図】図1
