74、翰·迪爾公司、卡特彼勒公司、德國利渤海爾公司及日本小松制作所都生產(chǎn)和銷售全液壓推寺機(jī)與裝載機(jī)。靜液壓傳動(dòng)不使用液力變矩器,還省去了離且器與行車制動(dòng)器及部分機(jī)械傳動(dòng)機(jī)構(gòu),能利用安全閥對(duì)機(jī)械和液壓系統(tǒng)實(shí)現(xiàn)過載保護(hù),并以較小的索引功率發(fā)揮最大的索引力,其剩余的功率可用在機(jī)器的輔助操作上。</p><p> 德國的德馬克公司和利渤海爾公司公別于1954年和1955年率先開發(fā)了全液壓挖掘機(jī),但靜液壓傳動(dòng)在挖掘機(jī)

77、公司還試制了電動(dòng)車輪傳遞行駛動(dòng)力。德國福格勒公司還試制了電傳動(dòng)的瀝青攤鋪機(jī),該機(jī)的所有回轉(zhuǎn)系統(tǒng)都用電馬達(dá)帶動(dòng),只有料斗開合與慰平板找平油缸仍使用液壓傳動(dòng)。另外就是在作業(yè)區(qū)域移動(dòng)較小的采礦工地上,使用了電力拖動(dòng)的大型挖掘機(jī)的裝載機(jī),這種電力拖動(dòng)使用電纜傳輸動(dòng)力而不必在機(jī)器上安裝發(fā)動(dòng)機(jī)。</p><p> 3、人機(jī)工程創(chuàng)新:以人為本與簡化操作</p><p> 20世紀(jì)80年代以來,世界上
78、許多大的工程機(jī)械制造公司都投入很大的人力和資金促進(jìn)現(xiàn)代設(shè)計(jì)方法學(xué)的研究和應(yīng)用。人機(jī)工程學(xué)是“以人為本”的設(shè)計(jì)思想,注重機(jī)器與人的相互協(xié)調(diào),提高人機(jī)安全性、駕駛舒適性,方便于司機(jī)操作和技術(shù)保養(yǎng),這樣既改善了司機(jī)的工作條件,又提高了生產(chǎn)效率,有的國家對(duì)工程機(jī)械的振動(dòng)、噪聲、廢氣排放和防翻滾與落物制定了新的標(biāo)準(zhǔn),甚至付諸法律?,F(xiàn)在各類工程機(jī)械都是設(shè)計(jì)有防翻滾和落物保護(hù)裝置,以保護(hù)司機(jī)的人身安全,并且都是與駕駛室分別設(shè)計(jì)和安裝。駕駛室內(nèi)有足夠的

81、相位差180°的干擾聲波,這種“抗噪聲”與發(fā)動(dòng)機(jī)排氣的噪聲相抵消,從而過到消聲的目的。這種電了消音器還可用于消除發(fā)動(dòng)機(jī)的基本噪聲和駕駛室內(nèi)的噪聲。通過消音和隔離的工程機(jī)械駕駛室內(nèi)噪聲可以降低到70dB(A)以下。</p><p> 另外,通過集中潤滑、自動(dòng)潤滑及故障自動(dòng)報(bào)警,大大減少了工程機(jī)械的維修工作量。德萊賽公司裝載機(jī)鉸接軸的潤滑周期可延長到2000h,更換機(jī)油和濾清器的周期延長到250h;卡特彼
82、勒公司裝載機(jī)的日常檢修時(shí)間縮短到3.45min,使用100h的技術(shù)保養(yǎng)時(shí)間也僅有6-7min。</p><p> 4、外觀造型創(chuàng)新:工業(yè)設(shè)計(jì)與環(huán)境協(xié)調(diào) 現(xiàn)代科學(xué)技術(shù)的高速發(fā)展,推動(dòng)著社會(huì)的進(jìn)步,給人類帶來了高度的物質(zhì)文明與精神文明。工業(yè)設(shè)計(jì)即是工業(yè)產(chǎn)品的造型設(shè)計(jì),也稱其為產(chǎn)品的藝術(shù)造型。機(jī)械產(chǎn)品的藝術(shù)造型應(yīng)能體現(xiàn)其功能的合理性及外在質(zhì)量的統(tǒng)一性,還應(yīng)體現(xiàn)出產(chǎn)品的技術(shù)先進(jìn)性和符合時(shí)代感的審美要求?! ?duì)于工
83、程機(jī)械,有人說“貨賣一張皮”那是言過其實(shí),但不重視造型設(shè)計(jì)肯定是不可取的。工程機(jī)械的造型設(shè)計(jì)可以使機(jī)器的形態(tài)與其結(jié)構(gòu)、功能及使用要求相統(tǒng)一,并與人的生理及心理相協(xié)調(diào)。這種造型設(shè)計(jì) 應(yīng)包括各部的比例得當(dāng),形體流暢、色彩協(xié)調(diào)、儀表布置美觀以及便于直觀操作和有醒目的商標(biāo)符號(hào)。現(xiàn)在世界各大公司都非常重視產(chǎn)品的工業(yè)設(shè)計(jì) ,并且出現(xiàn)了專門的研究和設(shè)計(jì)機(jī)構(gòu)。</p><p> 居世界領(lǐng)先地位的壓實(shí)機(jī)左制造商——寶馬公司,其第
84、三化壓實(shí)機(jī)械的機(jī)器造型由工業(yè)設(shè)計(jì)專家Louis.L.lepoix設(shè)計(jì),產(chǎn)生了良好的綜合效果。該系列拆裝更換濾清器、傳動(dòng)件、軟管及日常保養(yǎng)都是很方便。采用圓弧形的現(xiàn)代駕駛室和在傾角的發(fā)動(dòng)機(jī)罩視野開闊、線條流暢,具有時(shí)代氣息。駕駛方向盤的高度與傾角可調(diào),選用舒適的高靠背可調(diào)減振座椅,給駕駛員準(zhǔn)備了良好的操作環(huán)境。儀器儀表盤設(shè)計(jì)合理,易于觀察和控制,發(fā)動(dòng)機(jī)罩的傾斜給駕駛員提供了良好的視角。液壓轉(zhuǎn)向器轉(zhuǎn)移到了駕駛室外,以減少駕駛室內(nèi)的發(fā)熱與噪聲
85、。圓弧形的擋風(fēng)玻璃和駕駛室的四個(gè)外支承可隔離噪聲與振動(dòng),使室內(nèi)的噪聲低于70dB(A)。</p><p> 其它的許多工程機(jī)械也都是不同程度地注重了工業(yè)設(shè)計(jì),例如零部件布置盡量下移,以降低整機(jī)重心;適當(dāng)?shù)財(cái)U(kuò)大支承面積,以增加機(jī)器的穩(wěn)定度;左右布置盡量對(duì)稱,以符合人的美感;去掉一些外觀造型的尖角、棱邊,以顯示線條的流暢等。工程機(jī)械的油漆更是其工業(yè) 設(shè)計(jì)的重要內(nèi)容,整機(jī)的色調(diào)應(yīng)能引人注意,增加作業(yè)環(huán)境的安全,并與野
86、外施工現(xiàn)場(chǎng)的綠樹田野相映襯、協(xié)調(diào),使用套色的水平腰線和增加下車的色彩濃度可以增加機(jī)器的視覺穩(wěn)定性等。</p><p> ?。怠⑷斯ぶ悄軇?chuàng)新:靈性機(jī)器與機(jī)器人化</p><p> 工程機(jī)械在工程建設(shè)領(lǐng)域代替了人的體力勞動(dòng),擴(kuò)展了人的手腳功能,但傳統(tǒng)機(jī)械還未能解決好人的體力和生理負(fù)擔(dān)問題,更不要說解脫人的精神和心理負(fù)擔(dān)了?,F(xiàn)代化工程機(jī)械應(yīng)該是賦予了其靈性,有靈性的工程機(jī)械是有思維頭腦(微電腦
