THE OVERALL DESIGN OF LIGHT TRUCK
ABSTRACT
This light truck must have adequate hauling power and high
working efficiency. The purpose of the overall design is to coordinate
the subassemblies got together to avoid interfering between them. And
then making the truck’s movement is veracity, and to ensure the ride
comfort. The design of the cab must make the driver fortable.
The pay cube should be big enough to fulfill the rating carrying ability,
but we have to consider the tightest turning radius and flexibility as
well. There shouldn’t be interfere among steering drag rod and road
spring of front suspension in the chassis. The subassemblies must be
fixed to the chassis firmly to prevent syntony in the driving.
Main work is as following in this design: the General arrangement,
including selecting the main technology parameters, the engine, the
tires and so on; the Calculating of Stability , involving portrait stability
and landscape orientation stability while driving, the tightest turning
radius; the Power performance calculation, including the calculating of
speeds on all gear ratios, gradability, acceleration characteristic, the
balance between driving force and running resistance, as well as the
power; the Calculation of Fuel Economy.
Through the generalized analysis, computation, confirmation, we
confirm that this design has on the whole satisfied the description
requirements.
