“…The drive axle assembly is the pivotal system within the automobile chassis and encompasses various components such as the drive axle housing, the main reducer, the differential, the drive shaft, and the wheel reducer. The transmission device mainly includes the main reducing driving gear, the main reducing driven gear, the differential planetary mechanism planet gear, the drive shaft gear, and the wheel planetary reducing planet gear [37]. Figure 1 illustrates the positioning of the drive shaft within the drive axle assembly.…”

This paper investigates the failure mechanism of the rear drive shaft in a modified pickup truck which had operated for about 3000 km. The investigation included macroscopic and microscopic evaluation to document the morphologies of the fracture surface, measurement of the material composition, metallographic preparation and examination, mechanical testing, and finite element modelling and calculations. The results obtained suggest that rotation-bending fatigue was the primary cause of the drive shaft failure. The crack initiation is located in the root of the machined threads on the drive shaft surface and expanded along the side of the machining line surface. The main cause of fatigue cracks is attributable to a high stress concentration owing to a large unilateral bending impact under overload. Meanwhile, the bidirectional torsional force also produces a higher stress concentration and thus accelerates the fatigue crack to expand radially along the surface. Furthermore, the hardness of the central section of the drive shaft was marginally below standard. This deficiency results in harm to the bearings and other mechanical components, as well as expediting the enlargement of cracks. Finite element analysis revealed significant contact stress between the bearing and drive shaft, with stress levels exceeding the fatigue limit stress of the parent material. This highlights the need for reevaluation of the heat treatment process and vehicle loading quality to enhance the drive shaft’s longevity.

“…In an equally popular variant, angular velocities and torques are determined using the lever analogy method and nomograms [118][119][120][121][122][123][124][125][126][127][128][129][130]. Also very interesting is the combined method of determining the power flow and efficiency epicyclic transmission presented in references [131][132][133][134][135][136][137][138][139][140], where the Lagrange multipliers and kinematic constraints are used to determine the power flow and to verify the normal power flow balance. The accuracy is increased in this method by including virtual power in the analysis, where virtual power was determined in a non-inertial frame of epicyclic planetary gear.…”

So far it is believed that, for every series-parallel planetary gear system (PGS), as a coupled gear, a very harmful phenomenon of power circulation must occur in at least one of its closed circuits. In this paper (Part I) and in the next two (Part II and Part III), it will be shown that it is possible to construct a three-row series-parallel PGS in which this phenomenon can be avoided. For this purpose, in Part I, a detailed analysis of the kinematics and statics of a planetary gear with power circulation inside a closed loop was carried out. The determination of the angular velocities of gears and carriers is carried out using Willis formulas and the graphical-analytical method (for verification), while the torques are determined using free body diagrams. The magnitudes of angular velocities and torques were used to determine the directions of power flows with improved energy balance equations in the reference frame related to the stationary gear body and, additionally, only to verify the energy balance equation in the mobile reference frame related to the carrier hi (i=2,5,8). The improvement of the methods was based on the use of the original concept of distinguishing active torque from reactive torque, as well as active power from reactive power, which made it very easy to determine the directions of the power flow. The determined paths of the power flow, including the power circulation in the analysed PGS, are presented graphically.
