Suspension System

Suspension SystemFront suspension is replaced by

monoshock absorber

SUSPENSION• Front suspension : shock absorber

• Rear suspension : • MacPherson strut suspension.

STEERING SHAFT ANALYSIS

STEERING SYSTEM• Steering system : adjusted rack

and pinion forsmooth and smaller turning radius.• Using front and rear disk brake

to improve the car brake for fast

stop.

Safety Design

DESIGN SAFETY CONSIDERATION

Double layer wall design with heat and sound insulation material:• Front layer made from fiberglass

• Back layer made from lightweight Al plate

Firewall as heat insulator

DESIGN SAFETY CONSIDERATION

Made from Square tube natural

silk fiber / epoxy composites with

high density foam.• Benefits:

• High impact energy absorption

• High strength• Lightweight

• Environmentally friendly
