18、利車用玻璃升降器，其升降運動軌跡均為大半徑圓弧(R1250mm．2500mm)。夏利車的車窗玻璃安裝在舉升臂托架上，車窗玻璃在升降運動中，是利用托架內(nèi)的凹槽與滾輪軸軸向間隙，來不斷調(diào)整托架角度，以適應(yīng)車窗玻璃在導向槽內(nèi)的上下運動，因此實際工況與試驗臺上模擬的工況是有出入的。為了使試驗要求貼近實際工況，通過近百個樣件的對比試驗，采用統(tǒng)計與分析方法，找到了適宜的相關(guān)系數(shù)，是生產(chǎn)的各種玻璃升降器能與各種車型的車門門窗匹配，即保證了產(chǎn)品性能質(zhì)量

19、，也提高了試驗臺的實用價值。</p><p>　　由于臂式玻璃升降器制造工藝相對簡單，成本低，目前我國80％左右的汽車玻璃升降器采用臂式玻璃升降器。而柔式玻璃升降器從平穩(wěn)性、運動阻力來說大大優(yōu)于前者結(jié)構(gòu)更緊湊，且安裝和布置都較為方便，但目前我國關(guān)于柔式升降器尚無正式的國家標準。</p><p>　　軟軸式玻璃升降器在世界各種中高檔車輛特別是轎車上已被大量采用，是一種比較先進的玻璃升降器。近

20、年來國內(nèi)的引進汽車產(chǎn)品，如重汽斯泰爾、北京切諾基和南京依維柯等均采用這種升降器。目前已在國內(nèi)一些汽配廠如北京汽車玻璃升降器廠、南汽隨車工具廠、四川汽車廠附件廠等完成了有關(guān)軟軸式玻璃升降器的生產(chǎn)工藝的技術(shù)開發(fā)(引進)，可提供國產(chǎn)化產(chǎn)品。隨著其批量化生產(chǎn)水平的提高，亦可用于替代臂式玻璃升降器。</p><p>　　由于汽車結(jié)構(gòu)布局設(shè)計、制造成本、制造技術(shù)的要求，手動推拉式的車窗調(diào)整機構(gòu)仍為許多車輛采用。目前臂式及手動

22、。玻璃升降器是實現(xiàn)轎車車門玻璃升降運動的車門附件。通過玻璃升降器帶動玻璃托架作上下運動，從而使得車門玻璃沿著車門窗框的導槽或?qū)к壸魃颠\動。目前常用的玻璃升降器主要有叉臂式傳動和繩輪式傳動兩種常見結(jié)構(gòu)型式。后者能夠適應(yīng)玻璃在大曲率的弧形升降面上移動。此外有手操縱式卒電動兩種操縱方式。車門設(shè)計和布局中．正確選擇和布置玻璃升降器是保證玻璃升降操縱輕便、工作可靠的關(guān)鍵。</p><p>　　作為車門系統(tǒng)中的運動部件，升
