    装载机偶合器与变矩器有什么区别?
    2015-1-29 9:16:20

    装载机偶合器里只有泵轮和涡轮,而没有改变涡轮油液流动方向的导轮。工作时泵轮油液传给涡轮,然后又经涡轮返回泵轮,经涡轮返回泵轮的油液改变了旋转的方向,液流流向和泵轮旋转方向正好相反。发动机曲轴在旋转的同时,还需克服来自涡轮油液的反向阻力。发动机动力被削弱了,所以液力偶合器只有偶合工况,而永远不会有增矩工况。
    Shandong loader coupling, only a pump impeller and a turbine, the turbine without changing the direction of fluid flow guide rollers. When working pump oil to pass turbine wheel, and then through the turbine wheel return pump, oil pump

    through the turbine wheel return changed the direction of rotation, the flow direction and the opposite direction of rotation of the pump impeller. Engine crankshaft while being rotated, the need to overcome the resistance from the

    reverse of the turbine oil. Engine power is weakened, so that only the coupling fluid coupling condition, and never have increased torque conditions.

    装载机变矩器中泵轮快速运动时,涡轮受到载荷和行驶阻力限制转速较慢,泵轮和涡轮间产生了转速差。这个转速差存在于整个变矩区。这个转速差就形成了残余能量。即由于泵轮转数快于涡轮转数,所以泵轮流向涡轮的油液除了驱动涡轮外,还剩余一部分能量,这就是残余能量,泵轮和涡轮的转数差越大残余能量就越大。
    When the torque converter pump wheel loaders Shandong fast moving, turbine load and driving resistance by the slower speed limit, between the pump and turbine produces a speed difference. This speed difference exists in the entire variable torque area. This speed difference on the formation of residual energy. That is, since the number of pump rotation is faster than the number of revolutions of the turbine, so that the oil pump to the turbine in turn drives the turbine in addition to, but also the remaining part of the energy, which is the difference between the number of revolutions of the residual energy, the pump impeller and the turbine, the greater the greater the residual energy.

    装载机变矩器就不同了,泵轮和涡轮的转速差越大,残余能量就越大,油液流动的速度就越快,流动的角度就越大。在转数差较大时,涡轮的油液就冲向导轮的正面。导轮由于单向离合器的锁止作用,而不能向左旋转。这样流经导轮的油液就改变了流动的方向,直接作用于泵轮叶片的后部,于是油液的残余能量就增大了泵轮的转矩。残余能量越大,增矩效果就越好。只有在泵轮转数高于涡转数时才能产生残余能量,才能使转矩增大,在涡轮制动时其变矩比达到最大值。
    Shandong loader torque converter is different, the speed difference between the pump and turbine is larger, the greater the residual energy, the faster the speed of the oil flow, the greater the angle of flow. When rotating speed

    difference is large, fluid turbine guide on the red front wheel. Since the role of the guide wheel lockup clutch of the one-way, but can not be rotated to the left. Thus the oil flows through the guide wheel to change the direction of flow, acts directly on the rear of the impeller blades, then the residual energy of the oil increases the torque of the pump impeller. The larger the residual energy, increased torque, the better. Only when the pump is higher than the rotation number of vortex revolutions to generate residual energy, in order to make the torque increases, the turbine braking torque ratio reaches its maximum value.
