電磁閥之所以歸劃于自動化儀表行業中的執行器部分，雖外表與其他-些手動閥相似，甚至略顯粗糙,但內部結構卻十分精細，與一般手動閥門有著本質的區別。打個簡單的比喻來說,普通手動閥的開關完全靠人工用力的大小來操作，而電磁閥則完全靠自身的功能達到控制目的，而非人力所為再者電磁閥區別于其他閥門的是因為內部結構不同，所以不同的工作介質不能通用一種閥門，一旦確定介質種類而選定的產品則不能與不同介質混用，否則會導致電磁閥失靈或損壞。
力士樂DA控制是閉式油路純液壓機械控制，是靜壓自動變速機構。自動驅動控制:使得行駛驅動如自動變速轎車，踩油門起步，操縱油門踏板就能改變靜壓傳動流量，改變車速。防失速控制:自動調整液壓泵吸收功率，在過載時會自動減少泵的排量，例如:當行駛阻力增大時和當作業裝置工作消耗部分功率時，能防止發動機熄火和失速。
其特點是液壓泵和油門踏板之間無直接聯系，不需要任何操縱裝置和電子裝置,液壓泵的控制是完全自動的。DA控制經許多年和成千臺不同機械使用考核(叉車、裝載機和其它車輛)，證明了其可靠性、耐久性，也驗證了其獨特概念的正確性。
DA控制油路及基本工作原理
DA控制油路符號原理，踏油門踏板,發動機轉速上升，其帶動的補油泵轉速隨之上升，其流量成比例增加。該泵流量由轉速感應閥(帶測量節流孔的DA閥)檢出。通過DA閥的流量越大,則液壓泵的排量越大，泵輸出流量增大，車速隨之提高。作用在斜盤變量機構上的力。
1.控制壓力
發動機帶動的補油泵輸出油液經測量節流口產生壓降AP,經DA控制閥放大后產生控制壓力P3o經節流口流量Q和壓降AP、控制壓力P3的關系。影響控制壓力曲線的因素:控制壓力的大小與DA閥的結構(放大倍數)、調節狀態、節流孔及補油泵流量(轉速、效率)有關。
一般可變的參數為:調節狀態和節流孔的大小;補油泵的效率基本上對其影響很小。
(1)節流孔
根據節流口直徑及補油泵流量可以確定節流口前后的壓差:因此，借助于改變節流口的直徑就可以改變控制壓力曲線的“陡度”，作為經驗數值:一般節流口直徑改變1/10mm時，控制壓力曲線的調節終點大約改變100rpmo。
(2) DA閥的調節
利用改變DA閥中調節彈簧預緊力的大小也可以使控制壓力特性曲線產生平移;從其力平衡方程式中也可以很容易地看出:彈簧預緊力的提高，會導致控制壓力的下降，反之亦然。
這樣，對于驅動泵的調節也就意味著:擰入調節螺釘會使控制壓力下降，調節起始，點就會隨之，上升(車輛在較高轉速時才會啟動!)。
2.變量油缸活塞彈簧回到中位的作用力
在回位彈簧作用下，油泵回到中位零排量，將油泵從零變至大排量需克服彈簧力。例如:當控制壓力為5bar 時，斜盤開始變量，到控制壓力為15bar時，泵處于大排量。
3.與油泵輸出油壓有關的反推力
反推力取決于配流盤上的高壓配流口位置。在完全對稱的情況下(配流盤無偏轉)，使斜盤正偏轉及負偏轉的分力a和b大小相等。同理低壓側也如此，由于低壓側所產生的使斜盤偏轉的力(或稱力矩)相比之下很小，可以忽略，在這種情況下，由泵的高壓側所產生的對斜盤的作用力是平衡的(a=b)。
如將配流盤沿著傳動軸的旋轉方向偏轉一個角度B,則a>b,作用在斜盤上的反推力會使斜盤向零排量位置回擺，變排量時控制壓力需克服此推力。
(1)對壓力增益曲線的影響
斜盤傾角接近零時，變量油泵對中彈簧不起主要作用，主要靠時鐘調節(配流盤高壓窗口偏離中心位置的角度)影響壓力增益曲線。
(2)對流量特性曲線的影響
其影響與泵輸出壓力大小有關，隨著輸出壓力增大影響增大。
2.步進(微動)功能
通過人工調節改變DA控制來實現步進功能，可實現與發動機轉速無關的，由人工來控制的行走速度，在工作裝置需要發動機高轉速大流量時，行走裝置卻可低速行駛，實現合理的功率分配。
(1)通過手柄(或踏板)人工操縱改變DA閥的彈簧力來調節控制壓力
(2)在DA閥輸出的控制油路上連接人工機械操縱，可調節式回油節流閥來改變控制壓力P3
(3)在DA閥輸出的控制油路上連接人工機械操縱，可調式減壓閥或人工液壓操縱(例制動油壓)可調式減壓閥。
油門控制踏板和微動閥可調杠桿通過機械連桿機構相連。由于該機構存在空行程S (可調節)，因此在發動機小油門時，油門操縱微動閥可調杠桿不動，當油門到達一定位置(發動機轉速一定)， 空行程消除，繼續加大油門，將帶動微動閥可調杠桿轉動，DA閥彈簧力增大，控制壓力下降，這樣當發動機油門開度(轉速)到達一定位置，油泵排量不會隨之增大，行走泵負，荷得到限制。2000rpm 到達大排量，2000-2500rpm 時(負荷不增大)力士樂稱為“部分步進”。
DA控制車輛的工作特性
DA控制車輛的所有工作點都在三維曲面上,分析以下三種典型行駛工況，就能了解其工作原理:
1.車輛加速工況
(1)原地起步時，發動機械低怠速狀態，DA 泵在零排量;
(2)踩油門，發動機轉速上升開始建立壓力，但由于不能克服行走阻力，車輛尚未起步;
(3)加大油門踏板，車輛克服行駛阻力，起步行走;
(4)繼續加大油門，發動機轉速升高，油泵排量增加，車速提高;
(5)當車輛接近大車速油壓略降低，因無進一步加速需要，車輛只需克服摩擦阻力。
2.車輛爬坡工況.
(1)在平地上以大車速行駛(液壓泵全排量大流量),壓力相應于克服其滾動阻力和風阻力;
(2)進入坡道，所需牽引力增加,液壓系統壓力上升，發動機輸出動力增加，轉速下降，DA閥使液壓泵排量減小，按所需牽引力增加的大小，發動機功率和液壓泵功率取得新的平衡。
3.車輛失速狀態(例:裝載機以一定車速插入料堆進行鏟裝)
(1)在平地上以一定車速前進，克服行駛阻力，產生一定油壓;
(2)接觸料堆,所需牽引力增加，油壓提高，同時壓力感應DA泵使油泵排量下降，防止發動機過載;
(3)完全功入料堆，系統油壓進- -步提高，發動機隨負荷增加，轉速進一步降低;
(4)系統壓力達設定值，DA泵壓力切斷功能，使油泵排量降低至能保持系統大油壓(相應于大牽引力)的狀態，同時使得系統不過熱。
裝載機液壓行走系統
HST裝載機是全液壓驅動機械，行走和工作裝置可實現綜合控制。目前，新開發的小型裝載機幾乎已100%采用HST,并有向大型裝載機發展的趨勢。與傳統的液力機械裝載機相比，具有很大的優勢。

挖掘機械一般由動力裝置、傳動裝置、行走裝置和工作裝置等組成。單斗挖掘機和斗輪挖掘機還有轉臺，多斗挖掘機還有物料輸送裝置。動力裝置有柴油機、電動機、柴油發電機組或外電源變流機組。柴油機和電動機大多用于中、小型挖掘機械，用一臺原動機集中驅動，兩者可互換。柴油發電機組和外電源變流機組用于大、中型挖掘機械，用多臺電機分散驅動。行走裝置主要用來支承機器、使機器變換工作位置和轉移作業場地；另外，鏈斗式挖掘機和環輪式挖掘機的鏟斗，隨著行走裝置的連續行走而切削土壤。行走裝置有履帶式、輪胎式、步行式、軌行式、浮游式和拖掛式等幾種。作業場地固定、要求接地比壓較低時用履帶式；作業場地多變時用輪胎式；因施工條件特殊而必須架設專用軌道時，用軌行式；挖掘水下泥土用浮游式；小型單斗挖掘機的行走裝置無動力源時，用拖掛式；作業場地固定、機器重量大時，用步行式。步行式行走裝置大多用于單斗挖掘機中的大、中型拉鏟挖掘機和斗輪挖掘機。
工作裝置是液壓挖掘機的主要組成部分，挖掘機配置的是反鏟工作裝置，它主要用于挖掘停機面以下的土壤，但也可以挖掘*大切削高度以下的土壤，除了可以挖坑、開溝、裝載外還可以進行簡單平整場地工作。挖掘作業適應于開挖Ⅰ~Ⅳ級土，Ⅴ級以上用液壓錘或需爆破手段。反鏟工作裝置由動臂、斗桿、鏟斗、搖桿、連桿及包含動臂油缸、斗桿油缸、鏟斗油缸在內的工作裝置液壓管路等主要部分組成。

鏟土運輸機械是利用刀型或斗型切削裝置在走行中鏟掘、切削土石方，并能把所鏟削的土石方送到一定距離自行卸掉的機械，也包括專門用于越野運輸的自卸運輸車輛。屬于工程機械的一大類別。鏟土運輸機械由裝械機、推土機、平地機、鏟運機及礦用載重自卸車五大類組成。
鏟土運輸機械包括推土機、單斗裝載機、 鏟運機和平地機等機種，能完成刮削、鏟運、裝卸和 堆積散粒物料，平整場地，以及露天礦剝離等土石方 工程。依靠牽引力和速度進行作業，故對機械的行 走裝置和牽引傳動系有較高要求。常用柴油機驅 動，采用機械、液力機械或液壓傳動傳遞牽引功率。 行走裝置有輪胎式和履帶式，工作裝置多采用液壓 操縱。近年來，向大型化和超小型化發展;并研究自 控、遙控技術的應用，以擴大機械使用范圍，提高在 地下、水下和高原等惡劣條件下的作業能力;進行節 能和降低公害，提高機械的安全性和舒適性的研究， 以改善機械性能。

推土機是一種能夠進行挖掘、運輸和排棄巖土的土方工程機械,在露天礦有廣泛的用途。例如，用于建設排土場,平整汽車排土場，堆集分散的礦巖，平整工作平盤和建筑場地等。它不僅用于輔助工作，也可用于主要開采工作。例如:砂礦床的剝離和采礦，鏟運機和犁巖機的牽引和助推，在無運輸開采法時配合其他土方機械降低剝離臺階高度等。
推土機是一種工程車輛。前方裝有大型的金屬推土刀，使用時放下推土刀，向前鏟削并推送泥、沙及石塊等，推土刀位置和角度可以調整，能單獨完成挖土、運土和卸土工作。
推土機是土方工程機械的一種主要機械，按行走方式分為履帶式和輪胎式兩種。
裝載機是一種廣泛用于公路、鐵路、建筑、水電、港口、礦山等建設工程的土石方施工機械，它主要用于鏟裝土壤、砂石、石灰、煤炭等散狀物料，也可對礦石、硬土等作輕度鏟挖作業。換裝不同的輔助工作裝置還可進行推土、起重和其他物料如木材的裝卸作業。
在道路、特別是在高等級公路施工中，裝載機用于路基工程的填挖、瀝青混合料和水泥混凝土料場的集料與裝料等作業。此外還可進行推運土壤、刮平地面和牽引其他機械等作業。由于裝載機具有作業速度快、效率高、機動性好、操作輕便等優點，因此它成為工程建設中土石方施工的主要機種之一。
裝載機的鏟掘和裝卸物料作業是通過其工作裝置的運動來實現的。裝載機工作裝置由鏟斗、動臂、連桿、搖臂和轉斗油缸、動臂油缸等組成。整個工作裝置鉸接在車架7上。鏟斗通過連桿和搖臂與轉斗油缸鉸接，用以裝卸物料。動臂與車架、動臂油缸鉸接，用以升降鏟斗。鏟斗的翻轉和動臂的升降采用液壓操縱。
裝載機作業時工作裝置應能保證：當轉斗油缸閉鎖、動臂油缸舉升或降落時，連桿機構使鏟斗上下平動或接近平動，以免鏟斗傾斜而撒落物料；當動臂處于任何位置、鏟斗繞動臂鉸點轉動進行卸料時，鏟斗傾斜角不小于45°，卸料后動臂下降時又能使鏟斗自動放平。
裝載機主要部件包括發動機，變矩器，變速箱，前、后驅動橋，簡稱四大件1. 發動機2. 變矩器上有三個泵，工作泵（供應舉升，翻斗壓力油）轉向泵（供應轉向壓力油）變速泵也稱行走泵（供 應變矩器，變速箱壓力油），有些機型轉向泵上還裝有先導泵（供應操縱閥先導壓力油）3..工作液壓油路，液壓油箱，工作泵，多路閥，舉升油缸和翻斗油缸4. 行走油路：變速箱油底殼油，行走泵，一路進變矩器一路進檔位閥，變速箱離合器5. 驅動：傳動軸，主差速器，輪邊減速器6. 轉向油路：油箱，轉向泵，穩流閥（或者優先閥）轉向器，轉向油缸7. 變速箱有一體的（行星式）和分體（定軸式）兩種。
