THE DESIGN OF THE FRONT SUSPENSION AND STEERING SYSTEM OF THE
MINIATURE MOTORCAR TO CARRY PERSONS AND GOODS WITH 4 SEATS
ABSTRACT
In this graduation design, I am responsible for automobile's steering
system and the front suspension system design of the miniature
motorcar to carry persons and goods with 4 seats mainly..In weeks ,I
work hard to get the more useful information to do my work better.
With the helping of Mr Li and other teachers ,and observation on
vehicle in laboratory .I got a conclusion : the front independent
McPherson suspension is the best form for this automotive .
All focus on elastic part .Because elastic is the most important part
in them .And I have got some important data for my design work . If I
can?ˉt get those data ,I could not do my work in the following days .I
get many data ,but for front independent McPherson suspension the main
thing is about spring , such as spring rate ,middle diameter ,spring
wire diameter and so on .spring rate is the most important data for my
independent suspension ,it do many influence about suspension.
In the last I discussion shock absorber and anti-roll-bar a little,and
involve the basic of them and the important usefully in modern car?ˉs
suspension.
Because the motortcar we design is a kind of small output volume,
seeing that the gradual improvement of the road surface quality of our
country and effort of acting on the steering wheel are not very large,
so I choose the manual steering system.
Compared with others steering gear, though the negative efficiency of
the rack and pinion steering gear is high, but it have of simple
structure, compactness, shell adopt aluminum alloy or magnesium alloy
die casting, the weight of the rack and pinion steering system is much
smaller than others, transmission efficiency is up to more than 90%,
so in this design I choose the rack and pinion steering system.
Because the front overhang of the car is very short and the engine
occupied comparatively very big space, what is more, the minimum
transmission angle of the Ackerman steering has a very close relation
with installation distance of the steering gear, so I choose fit the
Ackerman steering in the back of the car conceding all those factor
above.
