What is suspension system
Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels
Serve a dual purpose – contributing to the car's handling and braking.
Protects the vehicle itself and any cargo or luggage from damage and wear
Different suspension systems
Conventional suspension system
Independent suspension system
Air suspension system
Hydro elastic suspension system
Conventional suspension system
Two wheels are mounted on either side of the rigid axle
When one wheel encounters the bump, both the wheel do not execute parallel up and down motion
So it gives rise to gyroscopic effect and wheel wobble
Rear driving wheels mounted on live axle suspended by laminated leaf springs and shock absorbers
Independent suspension system
Both the front and the rear wheel are utilized
Design incorporated in the front wheels
One wheel goes down ,the other wheel does not have much effect
Basic classification of the design
MacPherson Strut
Double Wishbone
Multi link
Air suspension
Comprises of compressor , suppling air to air tank
Pressure maintained – 5.6 to 7 kg/sq.m
Air bags – on each wheel
As load applied , air bags compressed actuating the levelling valve .
Air from the tank fills the compressrd air bag & hence raise the level of the frame.
Air from air bag gets released as load on chassis decreases .
