Types of car harness systems. What are their advantages and disadvantages?

The suspension system in a passenger car affects safety and driving comfort. It is responsible for maintaining the correct body height, improving vehicle handling and reducing impacts. Depending on how it was built, it can be more or less emergency. What are the types of suspension systems? What is the difference? To find out!

TL, д-

There are 3 main types of suspension systems: dependent, independent and semi-independent. In passenger cars, an independent suspension is most often used - the so-called McPherson Column, which provides the convenience of driving. Dependent suspension, featuring high strength, is mainly used in trucks and SUVs.

Dependent suspension

In a dependent suspension system the wheels of this axle are rigidly connected to each other... This means that if one wheel tilts, for example, due to bumps in the road, the other wheel will also change its position. The simultaneous movement of the axle body and the wheels forces to leave free space for vertical movements, which in passenger cars would lead to the need to raise the engine and limit the space in the trunk. So this type of solution is mainly used in trucks and SUVs.

The dependent suspension is characterized by strength, durability and low failure rate... However, this negatively affects driving comfort, limiting the vehicle's maneuverability. So in modern passenger cars it is used dependent leaf spring suspension using coil springs.

Independent suspension

In an independent system wheels of one axle move independently of each other... This solution increases the number of elements such as rods or wishbones, but increases driving comfort, which is why it is commonly used in passenger cars.

Macpherson's post

The most commonly used type of independent suspension is Macpherson's column... Although this design was patented at the turn of the 40s and 50s, it is still being modified and improved. It is based on combining shock absorber, spring and steering knuckle into one elementwhich performs all the functions of the suspension: leading, sprung, vibration damping and torsion. Simple design makes the McPherson stand lightweight and compacttherefore it takes up little space. Thus, the free space can be used for the engine compartment or the luggage compartment. This type of design also works. suppresses inequalitywhen providing easy driving i braking stability... However, the combination of several elements into one affects transmission of vibrations from the road surface to the car body... Column McPherson also susceptible to damage when driving on bumpy roads.

Semi-independent suspension

In a semi-independent suspension, the wheels of one axle interact weakly with each other. Most often it is used in it. trailing armsconnected by a crossbar. This beam is located in front of the wheel axle, is sensitive to torsional forces and acts as a stabilizer. This solution does not require high production and operating costs. It also causes the wheels to tilt slightly due to lateral forces, which improves traction. However, it does not insulate the body from shocks well. as a result of irregularities in the road surface.

The correct suspension design ensures a high level of safety and sufficient driving comfort. At the same time, the components used for its construction must be of high quality, so that everyday driving on roads with another, not always good, condition of the coating does not end with a frequent visit to the mechanic.
