LTU120C型沥青摊铺机由双泵、双马达驱动机身两侧履带实现行走,泵、马达均为闭式电比例变量控制。当操纵控制面板上的转向电位器时,控制系统给定左、右行驶泵不同的电流值,2个泵输出不同的流量,两侧行驶马达形成速差,从而使摊铺机转向。摊铺机有工作和行驶2个挡位,工作挡位时马达满排 The LTU120C asphalt paver is driven by double-track and double-motor driven crawlers on both sides of the fuselage. The pumps and motors are all controlled by a closed-loop proportional variable. When manipulating the steering potentiometer on the control panel, the control system gives different current values ​​for the left and right travel pumps. Two pumps output different flow rates, and the traveling motors on both sides create a speed difference, thus turning the paver. Pavers have work and driving gear 2, when the work gear full row of motors
