【正文】 rt requirements also along with it MT and AT have several fixed ratios. But the advantage of CVT is that the ratios are continuous at some extend. CVT is a gearing which is consisted of speed control mechanism and speed regulation institutions and pressure device or export agencies .CVT can achieve the transmission ratio of the continuous change ,which form optimum matching between transmission agent and engine behaviour, so economical efficiency and dynamic property of the car fuel oil will be improved,at the same time, it can improve convenience of control and riding fort .Obviously, the technology is indispensable in the society.KEYWORDS:CVT, constitute, economy, fort.5引言: 目前，在汽車上廣泛使用的自動(dòng)變速技術(shù)是由液力變矩器和行星齒輪系組合而成的自動(dòng)變速器技術(shù)，在大部分汽車制造商生產(chǎn)的城市用車中，該技術(shù)的平均裝車率已經(jīng)達(dá)到70%。由于CVT可以實(shí)現(xiàn)傳動(dòng)比的連續(xù)改變，使傳動(dòng)系統(tǒng)與發(fā)動(dòng)機(jī)工況形成最佳匹配，從而提高汽車的燃油經(jīng)濟(jì)性和動(dòng)力性，同時(shí)改善駕駛員的操縱方便性和乘坐舒適性。手動(dòng)變速器和自動(dòng)變速器均有幾個(gè)固定的傳動(dòng)比，而無(wú)級(jí)變速器的優(yōu)勢(shì)在于：在一定范圍內(nèi)，其傳動(dòng)比是連續(xù)的。常州工學(xué)院課程論文課題名稱： 汽車新技術(shù)概論 論文題目： 無(wú)級(jí)變速器 學(xué)生姓名： 顧 倩 霞 班級(jí)學(xué)號(hào)：10汽車—100106112012
