THE DESIGN OF LIGHT DRIVE
ABSTRACT
The main content of this literature is the process of the design and
calculation of the drive axle for mini-bus.
As one of ponent of vehicle drive line, its basic effect is to enlarge
the torques es from the drive shafts or directly from the transmission,
and distributes the torques to side wheels, and make the side wheels have the
differential drive axle has an important effect on vehicle performance, therefore,
we should keep a serious and earnest attitude during the course of design.
In the part of selection and argumentation ,a concrete description of
structure form of drive axle and its assemblies are made. In this design, it has
selected the single-grade main-reducer drive axle, it is two hypoid gears, it can
simplify the structure, reduce the size, make effect use of the space and
materials, reduce the whole quality..
In the part of designing conclusion and strength check, parameter of the
essential units such as the speed reduction,differential,wheel drive mechanism
and so on are selected. At the same time, the author makes the strength check
to the main speed reduction,differential wheels drive mechanism.
Key words ˖drive axle ,mini-bus ,differential gear, main-reducer
