【鋼鐵行業(yè)】力士樂(lè)比例閥0811404611 4WRPEH6C4B12L-2X/G24K0/A1M

REXROTH力士樂(lè)比例閥的工作原理如下：在不制動(dòng)時(shí),活塞在感載彈簧通過(guò)杠桿施加的推力F的作用下,處 于左端較限位置,這時(shí)閥門(mén)離開(kāi)閥座打開(kāi),使輸入輸出油路相通。當(dāng)開(kāi)始制動(dòng)時(shí),來(lái)自助力器的壓力為P1的制動(dòng)液由進(jìn)油口進(jìn)入,并通過(guò)閥門(mén)從出油口輸至后制動(dòng)管路.此時(shí)輸出液壓P,等于輸入液壓P1當(dāng)制動(dòng)踏板力加大時(shí),P1和P2同步加大。但由于活塞左側(cè)承壓面積大于右側(cè),致使活塞左側(cè)受到的力也大于右側(cè).

Rexroth力士樂(lè)比例閥的結(jié)構(gòu)和其它參數(shù)一定的情況下,調(diào)節(jié)作用的初始控制壓力P·的值取決于感載的比例閥感載彈簧預(yù)緊力的大小,其變化范圍在1.35～2.7MPa之I閏.因此只要使彈簧預(yù)緊力隨汽車實(shí)際軸荷的變化而變化,就能實(shí)現(xiàn)感載調(diào)節(jié)。感載比例閥安裝在左后輪附近,其安裝方式使得軸荷增加時(shí),感載彈簧被拉伸,折點(diǎn)液壓PS加大;軸荷減小時(shí).PS減小.這樣就使Ps隨載荷變化,實(shí)現(xiàn)了感載調(diào)節(jié),使前后輪制動(dòng)力分配更接近理想分配特性曲線。

比例控制閥是一種按輸入的電信號(hào)連 續(xù),按比例地控制液壓系統(tǒng)的流量,壓力和 方向的控制閥,其輸出的流量和壓力可以不受負(fù)載變化的影響。

比例閥與普通液壓元件相比,有如下特點(diǎn)：

（1）電信號(hào)便于傳遞,能簡(jiǎn)單地實(shí)現(xiàn)遠(yuǎn) 距離控制。

（2）能連續(xù),按比例地控制液壓系統(tǒng)的 壓力和流量,實(shí)現(xiàn)對(duì)執(zhí)行機(jī)構(gòu)的位置,速 度,力量的控制,并能減少壓力變換時(shí)的沖 擊。

（3）減少了元件數(shù)量,簡(jiǎn)化了油路。

同時(shí)電液比例閥的使用條件和保養(yǎng)與一 般液壓元件相同,比伺服閥的抗污染性能 強(qiáng),工作可靠。
