The chassis is the main frame of the
car. It is a tubular rigid structure with sheet metal body panels.
Under the chassis at the front and rear, there should have provision
for mounting of the frontal and rear parts. On the chassis, there
is a bay for housing six pieces of 12-volt battery, a seat for the
driver, a pair of pedals (acceleration and braking), and hand-brake
B. Frontal Part
The frontal part of the car consists
of a sub-frame on which the front suspension system is mounted.
Under the sub-frame, there are two steerable front wheels, brakes,
suspension arms, shock absorbers, coil springs, and a set of steering
linkages. On top of the sub-frame, there should be a mounting column
for the steering wheel.
C. Rear Part
The rear part of the car also consists
of a sub-frame on which the rear suspension system is mounted. Under
the sub-frame, there are two wheels, brakes, suspension arms, shock
absorbers, and coil springs. Apart from housing these components,
the rear part should have provision for mounting the motor and transmission
The transmission consists of an electric
motor coupled to a set of reduction gears and differential gears.
The transmission system must readily be mounted onto the rear part
of the car, the electric system directly linked to the accelerator
pedal, and control switch mounted on the chassis of the car.
The specifications of project are
according to the sub-project selected and will be distributed to
the students after the first meeting.
Students are required to:
- Design and manufacture the Multi-Purpose
Electric Car based on the given outline and specifications;
- Schedule the manufacturing process;
- Prepare a bill of materials and
a budget estimation for the whole project;
- Conduct commission testing;
Upon the completion of the MU project,
a group presentation and a group report are also required.
