德国REXROTH力士乐比例阀的工作原理及结构
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,zui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*分离而*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.
