1、1302R橡膠履帶拖拉機(jī)改進(jìn)設(shè)計(jì)摘要本設(shè)計(jì)為1302R型橡膠履帶拖拉機(jī)總體布置進(jìn)行的改進(jìn)設(shè)計(jì)，需要滿(mǎn)足新型轉(zhuǎn)向裝置、新型行走機(jī)構(gòu)和改進(jìn)的變速器布置的要求，對(duì)操縱機(jī)構(gòu)進(jìn)行布置，滿(mǎn)足人機(jī)工程的要求。改進(jìn)后的1302R橡膠履帶拖拉機(jī)將更加的符合用戶(hù)的要求，經(jīng)濟(jì)性，穩(wěn)定行都有所提高。橡膠履帶拖拉機(jī)較輪式和金屬履帶拖拉機(jī)有明顯的優(yōu)勢(shì)：1、良好的技術(shù)經(jīng)濟(jì)性2、更大的機(jī)動(dòng)性和可靠性3、良好的操縱舒適性鑒于此，橡膠履帶拖拉機(jī)的前途非常樂(lè)觀。作為農(nóng)業(yè)生產(chǎn)的大國(guó)，尤其是中國(guó)的農(nóng)機(jī)制造商，應(yīng)關(guān)注橡膠履帶拖拉機(jī)的發(fā)展方向，積極研究，縮短與國(guó)際先進(jìn)水平的差距，開(kāi)發(fā)適合中國(guó)使
2、用水平、經(jīng)濟(jì)購(gòu)買(mǎi)能力、生產(chǎn)和制造水平的新型農(nóng)業(yè)拖拉機(jī)。此次改進(jìn)設(shè)計(jì)便是朝此方向發(fā)展。在本次改進(jìn)設(shè)計(jì)中，繪制了牽引特性曲線(xiàn)，計(jì)算了整機(jī)質(zhì)心位置并進(jìn)行了人機(jī)工程的研究，整個(gè)設(shè)計(jì)滿(mǎn)足任務(wù)書(shū)要求。關(guān)鍵詞：總體設(shè)計(jì)，改進(jìn)，橡膠履帶拖拉機(jī)，牽引特性28The1302Rrubbercaterpillartractorimprovesthedesign
