INTRODUCTION
Suspension system
Separates wheel/axle assembly from body.
Active suspension
Uses separate actuators which can bring an independent force on suspension to improve the riding characteristics.
Construction:
104-actuator
108-suspension tower
110-1st bushing
114-2nd bushing
112-lower control arm
115-wheel well
117-moving armature
116-tie rod
118-spindle
120-passive suspension element
122-chassis
121-plate
124-tyre
The actuator requires rubber bellows to protect the moving armature as it slides in and out of actuator.
A passive suspension is coupled b/w suspension tower and lower control arm.
WORKING:
The active suspension can be arranged in series are parallel combination with the passive suspension such as spring etc..
The sensor is attached at the top cover to measure the motion of the suspension system.
It uses one or more sensors that can generate sensor signals to indicate the motion.
Then it is coupled to controller having processor.
It receives the signal & generates control signals.
The control signals are transmitted to amplifier that drives active suspension element.
ADVANTAGES
Superior comfort
Superior control
Reduces body roll during turns
Reduces need for camber roll during turns
Smoother ride than conventional shocks and struts.
Reduces noise and vibrations.
DISADVANTAGES
High initial cost
High repair costs
Complex systems
APPLICATIONS
System will be offered on high end luxury vehicles within the next 5 years.
The same technology has been applied in Military applications.
