2.1 the basic principle of the power transmission and scheme selection
High pressure cleaning car according to the function of the realization of the divided into two kinds of state: a normal work is driving condition, high pressure cleaning the car and general at the same car, realize the transfer function; vehicle 2 it is watering operations state, the state in the vehicle with very low, the speed of the high pressure water spray homework, cleaning the road. Due to the high pressure cleaning the car need driving and driven two aspects of the pump power, so the dynamic how to provide design is to consider when the primary issue.
At home and abroad and usually use the power distribution solutions has two, one is to adopt double configuration of the engine power transmission system, is main engine vehicles not alter, transmission system will not do change, use a Taiwan independence in vehicles outside the system of power auxiliary engine drive hydraulic system for high pressure pump provide motivation.
The advantages of this scheme is simple in structure, the price is low, the disadvantage is as the vehicle in the water spray work driving the speed, low speed less than 10 km/h, this time the main engine can't work in the best working point, that power allocation is not reasonable, can produce fuel and power waste, and occupy the space of vice engine body, less the water storage volume, vice vehicle engine installation added new vibration noise sources, the influence the stability of the vehicle.
Another plan is to use the vehicle engine vehicle transmission system and hydraulic system provide the power, through the points with FenDongXiang action, in the transfer road, driven by the main engine FenDongXiang to driving axle differentials, high speed movement; vehicle In injection homework road, driven by the main engine FenDongXiang to hydraulic system, on the one hand, control operation speed, on the other hand, the drive pump water spray.
The scheme with the foregoing scheme, its advantage is compared, giving full play to the engine power, make the vehicle in the water spray operations can still working at high speed rating of the work of the state, not only save one engine, reduce the fuel consumption, and engine exhaust emission index is more advantageous to achieve urban environmental protection requirement.

新型高壓清洗車
隨著工業(yè)的迅猛發(fā)展，環(huán)境污染顯得越來越嚴(yán)重，環(huán)保問題已是一個(gè)全球的戰(zhàn)略問題。為適應(yīng)城市環(huán)境衛(wèi)生建設(shè)的需要，及時(shí)清理城市路面，改善空氣質(zhì)量，環(huán)衛(wèi)車輛的開發(fā)和發(fā)展，已成為擺在我們面前的重要課題。我國(guó)城市化的發(fā)展，道路的增加及對(duì)環(huán)保要求的提高，使得對(duì)環(huán)衛(wèi)車的需求日益增加，高壓清洗車作為環(huán)衛(wèi)車輛中的一種，具有清洗道路、護(hù)欄和凈化空氣的作用，是城市環(huán)保的一種重要設(shè)備 。目前國(guó)內(nèi)生產(chǎn)的高壓清洗車技術(shù)落后，存在許多問題；國(guó)外的清洗車性能雖然優(yōu)越，但價(jià)格昂貴，需要大量的外匯，終究不是解決問題的辦法。為此，開發(fā)新型的高壓清洗車已成為我國(guó)城市環(huán)保工作中需要解決的重要問題。它不但具有自主知識(shí)產(chǎn)權(quán)，而且可以提高我國(guó)專用車的設(shè)計(jì)水平，帶動(dòng)我國(guó)環(huán)衛(wèi)車輛的自主設(shè)計(jì)開發(fā)及制造能力。
1 總體介紹
高壓清洗車主要由動(dòng)力系統(tǒng)、水系統(tǒng)、液壓系統(tǒng)、電控及操縱系統(tǒng)等部分組成。動(dòng)力系統(tǒng)為清洗車的行走和水泵提供動(dòng)力。水系統(tǒng)主要由高壓水泵、水箱、閥、噴嘴等組成，水流經(jīng)水泵后壓力可以提高到8MP，形成高壓射流噴射到路面，有效地沖洗路面的灰塵砂粒。液壓系統(tǒng)主要由液壓泵、馬達(dá)和和閥組等組成，控制車輛的行走和噴射動(dòng)作。電控部分主要由傳感器、單片機(jī)及顯示控制面板等組成 。本文開發(fā)的高壓清洗車主要技術(shù)參數(shù)如下：
額定容量 ；發(fā)動(dòng)機(jī)輸出功率 45KW；最大噴水寬度不小于3m；噴射工作時(shí)車輛行駛速度為 5km/h；噴射水壓不小于8MP；噴嘴總數(shù) 21 個(gè)；水泵最大噴水量 65km/h。
2動(dòng)力分配及切換系統(tǒng)
2.1動(dòng)力傳動(dòng)的基本原理及方案選擇
高壓清洗車根據(jù)其實(shí)現(xiàn)的功能分為兩種工作狀態(tài)：一是正常行駛狀態(tài)，此時(shí)高壓清洗車和一般的車一樣，實(shí)現(xiàn)車輛的轉(zhuǎn)移功能；二是噴水作業(yè)狀態(tài)，在此狀態(tài)下，車輛以很低的速度進(jìn)行高壓噴水作業(yè)，清洗路面。由于高壓清洗車需要行駛和驅(qū)動(dòng)水泵兩方面的動(dòng)力，所以該動(dòng)力如何提供是設(shè)計(jì)時(shí)需要考慮的首要問題。
目前國(guó)內(nèi)外通常使用的動(dòng)力分配方案有兩種，一是采用雙發(fā)動(dòng)機(jī)配置的動(dòng)力傳動(dòng)系統(tǒng)，即車輛主發(fā)動(dòng)機(jī)不作改動(dòng)，傳動(dòng)系統(tǒng)也不作改動(dòng)，使用一臺(tái)獨(dú)立于車輛動(dòng)力系統(tǒng)之外的輔助發(fā)動(dòng)機(jī)驅(qū)動(dòng)液壓系統(tǒng)為高壓水泵提供動(dòng)力。
該方案的優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)單，價(jià)格較低，缺點(diǎn)是由于車輛在噴水工作時(shí)低速行駛，其速度小于10km/h，此時(shí)主發(fā)動(dòng)機(jī)不能工作在最佳工作點(diǎn)，使功率分配不合理，會(huì)產(chǎn)生燃料和功率的浪費(fèi)，同時(shí)副發(fā)動(dòng)機(jī)占據(jù)車身的空間，相對(duì)減少了車輛的蓄水體積，副發(fā)動(dòng)機(jī)的安裝增加了新的振動(dòng)噪聲源，影響整車的穩(wěn)定性。
另外一種方案是采用車用主發(fā)動(dòng)機(jī)為車輛傳動(dòng)系統(tǒng)和液壓系統(tǒng)提供動(dòng)力，通過分動(dòng)箱的分動(dòng)作用，在轉(zhuǎn)移行駛時(shí)，動(dòng)力由主發(fā)動(dòng)機(jī)經(jīng)分動(dòng)箱到后橋差速器，車輛高速運(yùn)動(dòng)；在噴射作業(yè)行駛時(shí)，動(dòng)力由主發(fā)動(dòng)機(jī)經(jīng)分動(dòng)箱傳到液壓系統(tǒng)，一方面控制作業(yè)行駛速度，另一方面驅(qū)動(dòng)水泵噴水。
該方案與前述方案相比較，其優(yōu)點(diǎn)在于，充分發(fā)揮了發(fā)動(dòng)機(jī)的功率，使車輛在噴水作業(yè)時(shí)仍可以工作在高轉(zhuǎn)速的額定工作狀態(tài)，不但節(jié)省了一臺(tái)發(fā)動(dòng)機(jī)，降低了燃油消耗，同時(shí)發(fā)動(dòng)機(jī)尾氣排放指標(biāo)更有利于達(dá)到城市環(huán)保要求。整車的結(jié)構(gòu)更加合理，車輛的自重較低，蓄水空間相應(yīng)增加。綜上所述，單發(fā)動(dòng)機(jī)配置是一種更為合理的動(dòng)力配置方案，所以本文在新型高壓清洗車的設(shè)計(jì)中，采用了單發(fā)動(dòng)機(jī)的設(shè)計(jì)方案。
2.2功率的合理分配
為保證高壓水泵提供的噴射壓力恒定，驅(qū)動(dòng)該液壓回路的定量液壓泵必須工作在恒轉(zhuǎn)速的額定工作狀態(tài)，噴水作業(yè)時(shí)車輛的行駛速度與路面的噴射效果有關(guān)，也是不可改變的量，所以驅(qū)動(dòng)行駛的變量泵也要工作在恒轉(zhuǎn)速的額定工作狀態(tài)，行駛消耗的功率也為定值。因而，作業(yè)時(shí)需要的發(fā)動(dòng)機(jī)功率為定值。
2.3新型單軸分動(dòng)箱的設(shè)計(jì)
分動(dòng)箱是動(dòng)力分配系統(tǒng)的核心部分，傳統(tǒng)思想設(shè)計(jì)的分動(dòng)箱通常采用二到三軸結(jié)構(gòu)進(jìn)行動(dòng)力分配。本文設(shè)計(jì)的新型輕型高壓清洗車采用的底盤是五十鈴NKR55LLA 輕型底盤，用傳統(tǒng)結(jié)構(gòu)的分動(dòng)箱尺寸偏大，無法滿足尺寸要求。根據(jù)動(dòng)力分配系統(tǒng)的特點(diǎn)，自主設(shè)計(jì)開發(fā)了單軸傳動(dòng)的分動(dòng)箱，大大減小了分動(dòng)箱的尺寸，使車身結(jié)構(gòu)更加緊湊。
3液壓系統(tǒng)
液壓控制系統(tǒng)是噴水作業(yè)時(shí)各個(gè)動(dòng)作得以實(shí)現(xiàn)的關(guān)鍵，主要由變量泵、定量泵、驅(qū)動(dòng)馬達(dá)、液壓缸、冷卻器、集成控制閥塊、過濾器等組成。從實(shí)現(xiàn)的功能上來看，液壓系統(tǒng)由液壓馬達(dá)驅(qū)動(dòng)行走系統(tǒng)和液壓馬達(dá)驅(qū)動(dòng)噴水系統(tǒng)兩個(gè)子系統(tǒng)組成。
3.1液壓馬達(dá)驅(qū)動(dòng)行駛系統(tǒng)
變量泵 、液壓馬達(dá) 和相應(yīng)的液壓回路構(gòu)成了液壓行走子系統(tǒng)， 為系統(tǒng)的補(bǔ)油泵，與定量泵同軸連接。該系統(tǒng)由集成控制閥塊實(shí)現(xiàn)對(duì)油路和液壓泵的控制。變量泵及馬達(dá)的選型，基本根據(jù)前述的功率值來確定。
3.2液壓馬達(dá)驅(qū)動(dòng)噴水系統(tǒng)
液壓馬達(dá)驅(qū)動(dòng)噴水系統(tǒng)由定量泵 、定量液壓馬達(dá) 、水泵 、溢流閥、冷卻器、過濾器和液壓缸及疊加閥組 等組成。 為液壓缸和疊加閥組共同組成，用于控制噴水架的升降、伸縮等動(dòng)作。液壓油返回油箱時(shí)，經(jīng)過水冷卻器冷卻。
4水噴射系統(tǒng)
水系統(tǒng)是高壓清洗車的核心部分 主要由高壓水泵、噴水架、噴嘴、噴槍及閥等組成。水箱流出的水經(jīng)水泵后將水壓提高到8MP ，形成高壓射流噴射到路面。高壓泵的合理選取，對(duì)發(fā)動(dòng)機(jī)效率的最佳利用、最佳沖洗效率都有重要的影響，需要根據(jù)設(shè)計(jì)要求及發(fā)動(dòng)機(jī)參數(shù)等來確定高壓泵的功率、工作轉(zhuǎn)速和泵壓等參數(shù)。水系統(tǒng)設(shè)計(jì)中的主要問題包括以下兩個(gè)方面。
4.1伸縮式多自由度噴水架
噴水架是噴射系統(tǒng)的執(zhí)行機(jī)構(gòu)，安裝在高壓清洗車頭部，高壓噴嘴安裝在噴水架上。為增加路面噴射沖洗的寬度，設(shè)計(jì)了新型液壓控制伸縮機(jī)構(gòu)。工作時(shí)，安裝有噴嘴的兩根后排管向外伸出，與車頭前方的主噴管成一直線，同時(shí)向路面噴射高壓水流；工作完成后，后排管縮回主噴管后側(cè)。噴水架的離地高度也由液壓系統(tǒng)控制，同時(shí)還設(shè)計(jì)了機(jī)械式高度微調(diào)結(jié)構(gòu)，對(duì)高度進(jìn)行微量調(diào)節(jié)。
4.2噴水系統(tǒng)參數(shù)的優(yōu)化
高壓清洗車的用途是清洗出優(yōu)質(zhì)清潔的路面，所以，如何提高路面清洗效果、節(jié)約用水是設(shè)計(jì)時(shí)需要考慮的重要問題，也是以往的研究沒有重點(diǎn)考慮的問題。路面清洗的效果和許多參數(shù)有關(guān)。包括噴射高度 、噴嘴的形狀、噴射的壓力、噴射角度 、射流寬度 、噴嘴擴(kuò)散角 、噴嘴間距等 。通過大量的理論和試驗(yàn)研究，確定了噴射高度噴射的壓力、噴射的角度、射流的寬度、噴嘴的擴(kuò)散角 時(shí)，對(duì)路面進(jìn)行沖洗的效果最佳，路面的洗凈率在 以上，清洗單位面積的路面所消耗的水量和能量，都達(dá)到了最佳匹配值。
5電控及操作系統(tǒng)設(shè)計(jì)
電控系統(tǒng)要實(shí)現(xiàn)車輛的工作狀態(tài)顯示、監(jiān)測(cè)、報(bào)警和控制等功能。主要包括儀表顯示系統(tǒng)、儀表盤、液壓油驅(qū)動(dòng)車速表盤、液壓油溫顯示、油壓顯示、水箱的水位顯示及報(bào)警、噴水管工作狀態(tài)顯示、液壓系統(tǒng)運(yùn)行時(shí)間記錄等功能，整個(gè)系統(tǒng)采用模塊化設(shè)計(jì)，控制面板集成在駕駛室內(nèi)適當(dāng)位置，便于操作者控制操作。
水箱水量的監(jiān)測(cè)和預(yù)報(bào)是電控系統(tǒng)的重要環(huán)節(jié)，必須嚴(yán)格控制。水箱內(nèi)的水經(jīng)過冷卻器為液壓油冷卻后才進(jìn)入高壓水泵，所以水箱內(nèi)必須有相當(dāng)?shù)念A(yù)留水量。設(shè)計(jì)時(shí)采用了磁浮式液位傳感器，準(zhǔn)確測(cè)定液位的高度。操控系統(tǒng)主要包括操縱箱，動(dòng)力切換手柄，油驅(qū)車速踏板，左、中、右噴水管伸縮控制手柄，噴水柄前后擺動(dòng)控制手柄和車速踏板。操控系統(tǒng)的設(shè)計(jì)，操縱箱的布置、結(jié)構(gòu)，各手柄的位置，充分考慮了人機(jī)工程學(xué)要求，便于操控。
6總體結(jié)構(gòu)設(shè)計(jì)
在結(jié)構(gòu)上，整車包括底盤（帶駕駛室）、水箱、液壓油箱、水泵、分動(dòng)箱、噴水架等大型組件。水泵和液壓油箱平行布置在駕駛室和水箱之間，左右兩側(cè)采用外擺鉸鏈?zhǔn)杰囬T，開啟方便，便于維修檢查。水箱采用不銹鋼橢圓形結(jié)構(gòu)，外面配有裝飾側(cè)圍及裙邊。分動(dòng)箱布置在底盤內(nèi)液壓油箱和水泵下部，變速器和第二傳動(dòng)軸之間。整車采用Unigraphics 軟件進(jìn)行三維實(shí)體設(shè)計(jì)，并采用其裝配功能進(jìn)行了整車的虛擬裝配。
7 結(jié)論
新型高壓清洗車的研制，以提高路面沖洗效果和節(jié)約能源為核心，采用了單發(fā)動(dòng)機(jī)配置的動(dòng)力分配方式，充分發(fā)揮噴水作業(yè)時(shí)發(fā)動(dòng)機(jī)的功率，提高了噴水壓力；并對(duì)路面沖洗效果的影響參數(shù)進(jìn)行了優(yōu)化。對(duì)動(dòng)力分配系統(tǒng)、液壓系統(tǒng)、水系統(tǒng)、電控及操縱系統(tǒng)、總體結(jié)構(gòu)等都進(jìn)行了深入的研究。在車身外形、單軸分動(dòng)箱的開發(fā)以及路面沖洗效果等研究方面申請(qǐng)了數(shù)項(xiàng)專利。本文研制的新型高壓清洗車，經(jīng)過樣車試驗(yàn)，各項(xiàng)指標(biāo)都達(dá)到了預(yù)定要求。新型高壓清洗車的研制，為我國(guó)高性能高壓清洗車的自主開發(fā)，起到了良好的推動(dòng)作用。
