It` performance directly influence on the entire automobile，especially for the heavy truck .Because using the big power engine with the big driving torque satisfied the need of high speed，heavy-loaded， high efficiency， high benefit today`heavy truck， single reduction final drive axle is. Driving axle in power transmission, the basic function of the end of the drive shaft or transmission increases is by the torque,and from the power of the reasonable assigned to the right and left the drive wheels, also take effect on the pavement and frame or bo dy between the vertical and lateral and longitudinal strength and power. Generally by the reducer drive,differential and wheel transmission device and driving axle shell etc.car driving axle is the major car assembly, carrying a full load and reed car wheels.frame, and the ground monocoque body the suspension of the lead to vertical force, longitudinal force, transverse force and torque,and impact load; Driving axle also passed the transmission of the maximum torque, bridge is under adverse effect moment shell.car driving axle structure and design parameters in addition to the rellability of the parameters in addition to the reliablilty of the automobile and durability has a significant effect on the outside , also for the automobile driving performance such as power, economy smooth, through the sex,mobility and exercise has a direct impact on the dynamic stability, ect This design following the traditional designing method of the drive axle. First ，make up the main parts`structure and the key designing parameters; thus reference to the similar driving axle structure ， decide the entire designing project ; fanially check the strength of the axle drive bevel pinion ，bevel gear wheel ， the differentional planetary pinion， differential side gear ， full-floating axle shaft and the banjo axle housing ， and the life expection of carrier bearing . The designing take the spiral bevel gear for the tradional hypoid gear ，as the gear type of heavy truck`s final drive，with the expection of the question being discussed， further .
