Design of Steering Driven Axle for QAY125 Ton Automobile Crane

Driving axle loader is a key component for loader. For the steering drive axle of the QAY125 all terrain crane, the main parameters of the main reduction gears and drive axle housing have been designed and calculated. By adopting the method of optimum matching between engine and transmission system parameters, the ratio of the main reducer is determined by the optimum design. Considering the drive axle housing structure and the force is very complex, in order to ensure the strength of full static strength check calculation of impact load and emergency braking of the three cases, calculations show that the axle strength design can meet the design requirements. The half shaft diameter is calculated by using the maximum torque, when the half shaft diameter is 45mm, the material selection 42CrMo, the half shaft safety factor is 2.09, completely meet the use requirements.
