Abstract

The basic function of The driving axle is to increase the torque transmitted

from the transmission shaft or directly from the transmission, distribute the torque

to the left and right driving wheels, and make the left and right driving wheels

have the differential function required by the vehicle driving kinematics; at the

same time, the driving axle also bears the vertical force, longitudinal force and

transverse force and h consulting relevant data, the research

direction of the modern truck drive axle is mainly inclined to the single-stage

deceleration drive axle, because the design has higher transmission efficiency.

The task goal of this graduation project is to complete the design of the

scenic 330 automobile drive axle. Firstly, this paper introduces the composition

and characteristics of the drive axle. Then, the parameters of the designed vehicle

type are obtained by consulting the data on the Internet. Consult the mechanical

design manual to complete the design and calculation of the main parts of the

drive axle, and carry out the strength the calculation, the CATIA

software is used to construct the 3d model, and then the 2d graph is derived.

By analyzing the characteristics of driving axle of various structures, this paper

decides to adopt the central single-stage deceleration structure. This type of

driving axle has the advantages of simple structure and low manufacturing

process difficulty, so it is high cost-performance. In terms of gear selection,

thepaper chooses the bevel gear with higher transmission efficiency.
