Five Types of Car Suspension:

Since the car was invented, a few types of suspensions have been used to make driving more comfortable and safer. Many cars use independent front suspension, in this case each front wheel can move independently and attached separately. Some cars also have independent rear suspensions, which result in four-wheel independent suspension. Older cars use dependent rear suspension. Usually, you’ll find double wishbone and strut suspension in consumer cars. Right now, pneumatic suspension is becoming more popular in consumer cars and while electromagnetic suspensions are slowly being introduced.

Double-wishbone suspension:

It has a longer lower control arm and shorter upper control that is used to hold the wheel tightly to the frame. In this case, control arms are necessary to allow the wheel to move with better flexibility, just like a hinge that allows door to swing freely. If you check it closer, you’ll notice the lower arm is bigger because it needs to bear a significant amount of load when the car is driven. Ball-joint and rubber bushings are used to allow the wheels to pivot and rotate.

Multi-link suspension:

It is more advanced than the double-wishbone type and available in a number of configurations. It offers more flexibility, which results in better ability to deal with changes in driving conditions. Although this suspensions system still uses wishbone, each arm is connected separately to a spindle instead of as a single solid unit. It allows independent pivoting based on the steering wheel movement.

Strut suspension:

You can find conventional and modified strut suspension systems in consumer cars. On conventional struts, its coil springs are wrapped around a cartridge, while the modified strut suspension have a spring that is mounted remotely. These suspensions don’t have upper control arm. The wheels are hold in place by an upper strut mount.

Air suspension systems:

It is found on certain SUVs and luxury cars. This suspension system uses tubes controlled by sensors and air-filled bags that determine whether the suspension should be stiffened or softened, by pumping or letting the air out of the bags. Some air suspensions are automatic while others are controlled by the driver

Bose acoustic suspension:

It is developed by Bose, the same company that makes expensive and sensitive sound systems. The company comes up with an innovative suspension system that uses acoustic energy, a truly major automotive advance. Instead of using hydraulics, shock absorbers and conventional springs, the system has electromagnetic motors on all wheels. When the car moves, an amplifier sends signals to boost the wheel motors, allowing better suspension sensitivity than contemporary suspension system. The suspension allows the car to remain level when the accelerator and the brake pedals are pressed abruptly. Passengers may also notice far fewer shakes during sharp turn and vibrations are virtually eliminated.
