The different blanks were used in cold extruding forming tests, the main influence factors of forming faults were presented and the reasonable softening and lubricating technical conditions of blank were defined, then the cold extruding parts with high quality and accuracy, which satisfied the technical requirement of products, were produced. It was shown by production practice that this cold extruding process was an effective and economic nearnet forming processing technology.Key words： Driving gear。采用不同形狀毛坯進(jìn)行了冷擠壓成型工藝試驗(yàn)，指出了成型缺陷的主要影響因素，確定了合理的毛坯及其軟化、潤(rùn)滑工藝條件，成功地冷擠壓出符合零件技術(shù)要求的高質(zhì)量、高精度冷擠壓件。 Semiaxle of rear axle。D Center)【Abstract】Based on the weight reduction requirement for a heavyduty truck semiaxle of rear axle, a kind of high performance microalloy nonhardened tempered steel (FAS2340 Steel) was developed. The main influence factors in material development of semiaxle were discussed, and the performance and application of steel FAS2340 were analyzed and researched. The results showed that steel FAS2340 had good tenacity, so the fatigue capability of semiaxle improved greatly pared with the traditional steel semiaxle。 Wang Ganli。主題詞：重型載貨車(chē) 后橋半軸 非調(diào)質(zhì)鋼 Research on Development and Application of High Performance Nonhardened Tempered Steel for Semiaxle of Automotive Rear AxleLu Yun。結(jié)果表明，由于FAS2340鋼優(yōu)良的強(qiáng)韌性，使得FAS2340鋼半軸的疲勞性能比傳統(tǒng)用鋼半軸大幅提高；在滿(mǎn)足重型貨車(chē)后橋工作承載需求的前提下，減重10%。 Automatic control汽車(chē)后橋半軸用高性能非調(diào)質(zhì)鋼的開(kāi)發(fā)及應(yīng)用研究應(yīng)善強(qiáng) 曹正 鹿云 王敢利 馬汝忠（中國(guó)第一汽車(chē)集團(tuán)公司技術(shù)中心）【摘要】根據(jù)某重型貨車(chē)后橋半軸減重的需求,開(kāi)發(fā)了后橋半軸用高性能微合金非調(diào)質(zhì)鋼(FAS2340鋼)。 Air leakage。與傳統(tǒng)檢測(cè)技術(shù)相比，該檢測(cè)方法具有靈敏度高、壓力控制準(zhǔn)確、自動(dòng)化程度高、使用方便等特性。 clamping force controlHVAC風(fēng)道空氣泄漏檢測(cè)方法研究田韶鵬 楊莉玲 徐達(dá)偉 韓愛(ài)國(guó)（武漢理工大學(xué)）【摘要】介紹了一種用于自動(dòng)控制檢測(cè)采暖通風(fēng)與空調(diào)（HVAC）總成及風(fēng)門(mén)的空氣泄漏量的檢測(cè)方法。 electrical pulley actuation system。 Teachers University of Technology)【Abstract】Based on the discussion of advantages and disadvantages of the existing actuation systems for belt CVT, an electrical CVT pulley actuation system is presented with the dual motor regulating the working radius of drive and driven pulley, thus realizing variation of drive ratio, and the rubberVbelt CVT prototype with electrical pulley actuation system is developed.
