A system of mechanical linkages, springs, dampers that is used to connect the wheels to the chassis is known as suspension system. It has usually done two works-controlling the vehicle’s handling and braking for safety and keeping the passengers comfortable from bumps, vibrations etc.
SUSPENSION AND ITS DIFFERENT TYPES
It also helps to maintain correct vehicle height and wheel alingment.it also control the direction of the vehicle and has to keep the wheel in perpendicular direction for there maximum grip. The suspension also protects the vehicle itself and luggage from damage and wear. The design of front and rear suspension of a car may be different.
TYPES OF SUSPENSION SYSTEM
1)INDEPENDENT SUSPENSION SYSTEM
This system means that the suspension is set-up in such a way that allows the wheel on the left and right side of the vehicle to move vertically independent up and down while driving on uneven surface. A force acting on the single wheel does not affect the other as there is no mechanical linkage present between the two hubs of the same vehicle. In most of the vehicle it is employed in front wheels.
This types of suspension usually offers better ride quality and handling due to less unsprung weight. The main advantage of independent suspension are that they require less space, they provide easier steer ability, low weight etc.. Examples of Independent suspension are
2)DEPENDENT SUSPENSION SYSTEM
IN Dependent Suspension there is a rigid linkage between the two wheels of the same axle. A force acting on one wheel will effect the opposite wheel. For each motion of the wheel caused by road irregularities affects the coupled wheel as well.
It is mostly employed in heavy vehicles. It can bear shocks with a great capacity than independent suspension. Example of this system is
This type of system has both the characteristics of dependent as well as independent suspension. In semi-independent suspension, the wheel move relative to one another as in independent suspension but the position of one wheel has some effect on the other wheel. This is done with the help of twisting suspension parts. Example of semi-independent is
