The Designing of Heavy Truck Rear Drive Axles

Abstract

Drive axle is the one of automobile four important assemblies. 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￡?must exploiting the high driven efficiency single reduction final drive axle is becoming the heavy truck`developing tendency. 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 .??

Key words: heavy truck drive axle single reduction final drive
the spiral bevel gear
