伺服阀与比例阀的区别 

REXROTH力士乐比例阀与比例阀之间的差别并没有严格的规定，因为比例阀的性能越来越好，逐渐向伺服阀靠近，所以近些年出现了比例伺服阀。 

力士乐REXROTH比例阀，REXROTH阀工作原理REXROTH力士乐比例阀非要说差别，主要体现在一下几点： 

伺服阀中位没有死区，比例阀有中位死区； 

伺服阀的频响（响应频率）更高，可以高达200Hz左右，比例阀一般最高几十Hz； 

伺服阀对液压油液的要求更高，需要精过滤才行，否则容易堵塞，比例阀要求低一些。 

REXROTH力士乐比例伺服阀性能介于伺服阀和比例阀之间。 

REXROTH力士乐比例换向阀属于比例阀的一种，用来控制流量和流向。

力士乐REXROTH比例阀，REXROTH阀工作原理

力士乐Rexroth比例阀在使用过程中,应注意对感载比例阀的检查调整.当感载弹簧过松时,后轮制动力就会减小,此时应调整感载弹簧,但不可调得过紧,否则会使后轮制动力太大而失去侧向控制能力,发生甩尾。正确的调整方法是.在平坦的地面上使车身落地,车辆空载,调整感载弹簧,使杠杆与活塞间无间隙即可.在有条件的情况下,可采用精确的调整方法.通过测量前后轮制动管路压力,绘制压力分配特性曲线,确认调整是否合格。

德国Rexroth力士乐比例阀的工作原理，REXROTH力士乐比例阀结构，力士乐比例阀作用

REXROTH力士乐比例阀当左侧受力大于右侧受力与感载弹簧预紧力之和时（此时的压力为Ps）,活塞不断右移,最后使阀门与阀座接触而关闭,将输入输出油路隔绝,达到平衡状态。P1若进一步升高时,则活塞左移,阀门再度打开,制动液流入出油口,使P2也升高。

德国rexroth比例阀VT-NE30-2X的输入压力为零.即.;时,输出腔的压力通过比例阀皮圈凸筋间空酸从唇口泄去高压,同时,当比例阀芯所受的弹簧力大于向右的液压力时,比例阀弹簧将比例阀芯推回原始位置,使比例阀芯与比例阀皮圈内孔完全分离而完全泄压.此时输入输出压力为零.随着输入压力.增大,即左增大,使比例滑阀单向力平衡遭破坏.当<>&;6-时,比例阀芯左移与比例阀皮圈产生间隙形成节流并混合比倒阀常见的故障为:1,输入输出压力同步.2,低压时辅人输出压力同步,高压时输入输出压力正常.3,低压时输入输出压力正常,高压时输入输出压力不正常.,1994.№为零时为混合比倒圉工作性能试验示意图.试验时,先将管内的空气排净,然后分别取低,中,高三个压力进行试验,输入辅出压力符合即为合格。

Rexroth力士乐比例阀奥迪四轮驱动轿车制动系统在关闭ABS后,感载比例阀可用于防止后轮的过制动。当汽车直线行驶时,两后轮的制动压力可根据车辆载荷增减;当汽车左转弯时,左后轮载荷下降,由于感载比例阀位于左后轮附近,可同样起作用使两后轮的制动压力都下降.而当汽车右转弯时,右后轮载荷减小,汽车的侧向加速度使感载比例阀起作用,降低右后轮的制动压力。这样的自动调节使前、后轮的制动力分配和左、右后轮的制动力分配都接近理想的制动力分配,从而提高了制动安全性。
