叉车的运输能力主要决定于行走驱动机构。这种行走驱动机构既要能充份利用发动机的功率,对于缺乏训练的司机又要求它的操作简单。用内燃机带动的液力偶合器和液力变矩器对于这类叉车的制造厂提供了两种采用液力驱动的可能性。1.液力偶合器与带同步器的变速箱相结合采用摩擦离合器和齿轮变速箱及反向机构相连接,可以适当满足上述的要求。采用一个液力偶合器并没有使操作简化,但它能提高叉车的功效。内燃发动机的能量通 Forklift transport capacity is mainly determined by the walking drive. This kind of walking drive mechanism should not only make full use of the power of the engine, but also demand the simple operation of the driver who is lack of training. The use of internal combustion-driven fluid couplings and torque converters offers two possibilities for hydraulically driven operation for such forklift manufacturers. 1. Coupling of fluid coupling and gearbox with synchronizer The coupling of friction clutch and gearbox and reversing mechanism can meet the above requirements. The use of a hydraulic coupling does not simplify the operation, but it increases the efficiency of the truck. Internal combustion engine energy pass
