Suspension is a kind of connecting link between the vehicle and the road. It is through suspension, the car has properties such as manoeuvrability, comfort. Since the car has four wheels, two pairs, and the suspension is divided in two pairs: the front and back. So, what's the difference between the front and rear suspension?
Front suspension is designed, first of all, given the fact that it performs the functions of control and maneuvering, as on the front wheels to bear big load on stabilization and manoeuvring the vehicle. Given that all the elements are at the front of the engine, and thus the load on the front suspension is much more than the back. The rear suspension is more static position than the front.
For the comfort and smooth running of the car largely responsible rear suspension. The rear suspension can be divided into two main types: dependent and independent. From the very meaning of the word "dependent", it is clear that this type of suspension is characterized by the fact that both rear wheels are connected integral element. This element, usually a beam that connects the wheel of a car, suspended on two springs with two wheels and is connected to the frame of the car using a trailing arms. The main drawback of this design is a large mass, stiffness of turn. However, due to the cheapness and simplicity of a design are widely used in automobiles of middle and economy class.
Independent suspension is multilink suspension. The rear wheels are not connected to each other, and are Autonomous. This type of suspension is characterized by the fact that each wheel is held five separate arms, two of which are directly hold the wheel and the rest give it to the desired position. This type of suspension features more easily than with a dependent, and good fluency. This type of suspension is more complex, and accordingly and the price of production. Set on the car of a representative class.
Improving this type of suspension, which is installed on the modern expensive cars, is an active multi-link suspension. In addition to the structure described above, this type of suspension is characterized by the presence of an electric motor for each wheel, which regulates the position of the wheels, if necessary, directing the rear wheels in the right direction, i.e., the car has not two, but actually four driven wheels. The taxiing rear wheels with the help of the computer, which calculates the number of degrees must be a turning wheel. Active multi-link suspension is gradually replacing the traditional beam. Many manufacturers are beginning to put the active suspension for cars of middle class.
