Drive axle assemblies have several important functions. They must hold the wheels on, keep them upright, allow them to be turned (in front, on fourwheel drive and frontwheel drive vehicles) and propel the wheels forward or backward. They must drive the wheels in such a manner that one can turn faster than the other, yet both must receive torque. Drive axle assemblies must absorb the driving force of the wheels, and transmit it to the frame through springs, control rods, etc. The axle assembly provides an anchorage for springs, supports the weight of the vehicle and forms the foundation upon which the wheel brakes are mounted. Obviously, the axle assemblies must be well constructed, using quality materials. HOUSING The axle housing is usually made of stamped steel parts welded together. Or, the center section of the housing may be made of cast steel. Two basic types have been used: the BANJO type housing (in wide use) and the SPLIT housing (little used) consisting of two or more pieces. AXLES Two steel axles are placed inside the housing. Their inner ends almost touch。這種差速器的建立，通過(guò)螺旋錐齒輪傳動(dòng)，運(yùn)動(dòng)形式同準(zhǔn)雙曲面齒輪相同。 半軸轉(zhuǎn)速不同 當(dāng)汽車轉(zhuǎn)彎時(shí)，其內(nèi)部軸的轉(zhuǎn)速降低。盡管存在著很多的變化，但可采用摩擦裝置來(lái)實(shí)現(xiàn)正常運(yùn)動(dòng)。當(dāng)要求車輪快速轉(zhuǎn)動(dòng)時(shí)，外部半軸齒輪的轉(zhuǎn)速高于內(nèi)部半軸齒輪。大多是汽車采用半浮式，大部分貨車采用全浮式半軸支承。1 本科生畢業(yè)設(shè)計(jì)（論文）翻譯 英文原文名 DRIVE AXLE ASSEMBLIES 中文譯名 驅(qū)動(dòng)橋
