51、但是是在大夾角狀狀態(tài)下，傳動動效率隨擋位升高有增大趨勢；在外側(cè)側(cè)萬向節(jié)夾角角較大的條件件下，如果轉(zhuǎn)轉(zhuǎn)矩不變而轉(zhuǎn)轉(zhuǎn)速降低，則則傳動效率明明顯減小。主題詞：轎車 等速驅(qū)動軸軸 傳動效率率 Experimmentall Studdy on Transsmissiion Effficieency ffor Coonstannt Vellocityy Drivve Shaaft off CarMa Tiannfei Wang Deengfenng Haao Chuunguanng （Jilin Univeersityy）【Abstraact】Baased oon twoo consstant veloc
