Automotive Suspension consist of springs, shock absorbers and linkages that connects a vehicle to its wheels. Suspension systems serve two purposes — they contribute to the car's roadholding or handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations,etc. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different.
Periodic inspection of the bushings, shock absorbers and struts is required to keep the vehicle in good shape.
Suspension systems serve a dual purpose of contributing to the car's roadholding and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations,etc.
Automobiles have many important components that need to be in perfect working order for the vehicle to give a smooth and stable ride. The automotive suspension consists of, sway bar's, air bags, struts, shocks, springs and links these components have to be in good working order . If any of them are defective, the ride quality of the vehicle will be affected and will be un-safe to drive. Each of them has an important and specific function and this is why they are included in the vehicle.
The suspension system keeps the vehicle at a stable level and helps maintain traction between the wheel's and the road. It maximizes the friction between the tires and the ground that is under the car. Without it, the car would be difficult to control and not safe. This is because an upward force from the road would decrease the ease of steering the vehicle or accelerating and the tires may not cling to the road surface.
Coil springs are important suspension components. Springs that are too hard or too soft cause the suspension to become ineffective because they fail to properly isolate the vehicle from the road. Vehicles that commonly experience suspension loads heavier than normal have heavy or hard springs with a spring rate close to the upper limit for that vehicle's weight. This allows the vehicle to perform properly under a heavy load when control is limited by the inertia of the load. Riding in an empty truck used for carrying loads can be uncomfortable for passengers because of its high spring rate relative to the weight of the vehicle. A race car would also be described as having heavy springs and would also be uncomfortably bumpy.
In vehicle suspension systems, struts are most commonly an assembly of coil-over spring and shock absorber.The MacPherson strut combines a shock absorber and a spring in a single unit, by means of which each wheel is attached to the car body.Struts help to keep the car tires on the road when it is turning or moving. Struts hold the suspension system together.Without them, it would be impossible to operate the car safely. Tires may come off of the road and a crash or car accident may occur.
A shock absorber is a devise used to smooth out or dampen shock impulse,shock absorbers reduce the effect of traveling over rough ground, leading to improved ride quality and increase in comfort. While shock absorbers serve the purpose of limiting excessive suspension movement, their intended sole purpose is to dampen spring oscillations. Shocks on a car help to support it's weight.
stabilizer links and sway bar's on a car help to stabilize the car. They improve handling of the vehicle by preventing it from swaying or moving when the driver is turning. Also, it helps to absorb the car weight so that is does not bounce up and down too much. They also help to manage fuel efficiency of the vehicle. Without sway bars and stabilizer links, a driver could lose control of the vehicle and crash.
