Without an intervening structure, all of the wheel's vertical energy is transferred to the frame, which moves in the same direction. In such a situation, the tires can lose contact with the road completely.
What is dependent front suspension?
Dependent front suspensions have a rigid front axle that connects the front wheels. Basically, this looks like a solid bar under the front of the car, kept in place by leaf springs and shock absorbers. Common on trucks, dependent front suspensions haven't been used in mainstream cars for years.
What is a sway bar?
A sway bar is a metal rod that spans the entire axle and effectively joins each side of the suspension together.
Why are shock absorbers so sensitive?
All modern shock absorbers are velocity-sensitive — the faster the suspension moves, the more resistance the shock absorber provides. This enables shocks to adjust to road conditions and to control all of the unwanted motions that can occur in a moving vehicle, including bounce, sway, brake dive and acceleration squat.
What is the difference between sprung and unsprung mass?
Springs: Sprung and Unsprung Mass. The sprung mass is the mass of the vehicle supported on the springs , while the unsprung mass is loosely defined as the mass between the road and the suspension springs . The stiffness of the springs affects how the sprung mass responds while the car is being driven.
How do the four wheels of a car work together?
But the four wheels of a car work together in two independent systems — the two wheels connected by the front axle and the two wheels connected by the rear axle. That means that a car can and usually does have a different type of suspension on the front and back.
How do torsion bars work?
Torsion bars use the twisting properties of a steel bar to provide coil-spring-like performance. This is how they work: One end of a bar is anchored to the vehicle frame . The other end is attached to a wishbone, which acts like a lever that moves perpendicular to the torsion bar.
How do car suspensions work?
Let us find out how the car suspensions work and their complete mechanism. 1. Independent Suspension. In today’s automobile world, all the manufacturers have started to install independent suspension setup in their vehicles. It is because all the tires of the vehicle get the freedom to travel independently over the road.
Why do cars have suspensions?
The function of a car suspension system is to lift the car from the surface to trim down the impact of forces working on it. A car suspension keeps the car intact, which makes the controlling easier. If the car suspensions are absent in a car, then you might not be able to control the car properly. The main purpose of these suspensions is to maximize the resistance between tire and ground. It results in offering stability to the steering by which you can easily handle the vehicle.

what is a car suspension?
Suspension is the system of tires, tire air, springs, shock absorbers, and linkages that connects a vehicle to its wheels and allow relative movement between the two. Suspension systems must support both road holding/handling and ride quality, which is at odds with each other.
What Does a Car Suspension Do?
In short, your car’s suspension system is a protective lattice of shock-absorbing components such as springs and dampers. Your car’s suspension helps ensure you drive safely and smoothly by absorbing the energy of various road bumps and other kinetic shocks. In addition, it helps your tires stay in contact with the road by increasing tire friction.
Why is your car suspension so important?
Any modern car is equipped with a suspension due to its advantages. For example:
How does a car suspension work?
A suspension works on the principle of force dissipation which involves converting force into heat thus removing the impact that force would have made. It uses springs, dampers, and struts to achieve this. A spring will hold the energy while a damper will convert it into heat.

How does a car pivot work?
Outside the pivots the bar bends back and one end is attached to each wheel, usually through one or two flexible rubber bushes. When one wheel moves up it pulls up one end of the bar and the other end pulls up the other wheel, keeping the car level.
What is trailing arm suspension?
A trailing-arm suspension on a rear-wheel-drive car. The arm is attached to the rear wheel hub and broadens into a V whose two arms extend forward to pivot on the frame . The differential is fixed to the frame and the drive shafts have universal joints.
What is a wishbone suspension?
Wishbone suspension. A double-wishbone suspension. Wishbones are fitted at their outer ends to the top and bottom of the steering swivel member. The two forks of each wishbone extend inward to pivot on the frame. A tie rod - a steadying bar - is connected between the frame and the lower wishbone.
What is swing axle?
Swing axles may be at the front or rear. The system is like a beam axle cut in half and attached to pivots on the frame. Usually the half-axle is broadened into a V with front and rear pivots to keep it from twisting.
How many wishbones are there on a MacPherson strut?
There are two wishbones, one above the other, to keep the wheel upright as it rises and falls. MacPherson-strut suspension can be used at both front and rear. The wheel hub is fixed rigidly to an upright, telescopic, tubular strut which has its top end anchored to the frame or to a reinforced wing.
What is a leaf spring?
Leaf spring and MacPherson strut. A typical suspension system on a re ar-wheel-drive car. It has a live rear axle on leaf springs, and independent front suspension of the MacPherson-strut type with interior damper.
Where is the trailing arm on a bike?
A trailing arm is attached to the wheel hub at one end, and extends forward to a pivot on the frame. The arm may be broadened into a V shape with two pivots, either side by side or with the inner pivot slightly behind the front one - a semi-trailing arm. Trailing arms are usually found at the rear only.
How are suspension systems connected to each other?
On a non-independent system, commonly found on trucks and vans, the suspension systems are connected to each other by an axle fitted with leaf springs and a damper at each end. Forces acting on one side of the vehicle will also affect the other side.
What is the top section of a suspension called?
Whatever the type of damper, its job is to release the spring’s energy in a controlled manner. Most are in two sections. The top section is called the outer tube.
How does a damper affect a car?
When a damper begins to wear out, fluid can leak from it making it less effective. This affects the car’s ride and handling, and accelerates tyre wear.
What is double wishbone suspension?
Double wishbone suspension is the bedrock of independent systems and comprises two pressed steel or aluminium arms per wheel, one above the other, extending from the wheel hub to the frame of the car. A damper inside a coil spring is attached to the lower wishbone and at its other end to the car body.
What kind of springs do cars use?
Most modern car suspension systems use steel coil springs – one per wheel. However, if you look under an older car or a pick-up truck, instead of springs you’ll see narrow strips of metal stacked one on top of the other. These are leaf springs.
What is a torsion bar?
It’s called a torsion bar. It’s a long piece of metal attached to the car at one end and to the rest of the suspension system at the wheel end. When the car hits a bump, the suspension moves, causing the bar to twist and absorb the energy.
What is a MacPherson strut?

How does a suspension work?
How simple suspensions work. A suspension is essentially a damped spring producing opposing force when being compressed. Springs sustain the weight of the vehicle. Dampers oppose the spring movement, dissipating their energy and preventing them to bounce without control. The force produced by the springs depends on the distance they are compressed ...
What happens when a vehicle is accelerating?
If the vehicle is accelerating, braking or cornering the weight will be temporarily shifted among the wheels, varying their suspension positions accordingly. For instance, accelerating makes a certain amount of weight (depending on the actual acceleration) to be transfered from front wheels to rear wheels.
How does damper force work?
The force produced by the dampers depend on how fast the suspension is being compressed or elongated ( contact speed ), opposing the movement. When a wheel is lifted from the ground the suspension produces no force. At the slightest contact possible it also won't produce any force.
What happens when the center of mass of a vehicle is moved?
If the center of mass of a vehicle is moved (load, passengers...) the weight will be redistributed along the wheels and their suspensions will be compressed / elongated as result of the new weight distribution.
What happens when a spring is compressed?
As the spring gets more compressed , more force is produced proportionally to the contact depth: The compression limit is the suspension distance. Beyond this point the spring has reached its maximum force and cannot compress further. A hard contact with the rigid body is produced.
Is a vehicle suspension a harmonic oscillator?
Beware: a vehicle suspension is NOT a harmonic oscillator per-se. A suspension behaves as harmonic oscillator under certain conditions, and may be studied as a harmonic oscillator under those conditions. Read Application to real vehicles below.
What is the main job of a suspension system?
As the the suspension system’s main job is to absorb shock in order to protect the vehicle and its occupants, parts are built to be fairly durable. There are a few other components on modern vehicles that are as over-engineered as those found in the suspension system.
What is the purpose of suspension when stopping?
For smooth acceleration, suspension that prevents the car from squatting down in back when the throttle is opened is required.
What are the problems with a car?
Some possible problems with the body or ride to look out for include: 1 Body Roll: When the body of the car leans to the outside when cornering. All cars do this to some extent when going around a corner, but if the body of the car rolls too much then the shift in weight can cause the vehicle to spin, steer out of the turn prematurely, or lose traction on one or more wheels. 2 Bottom Out: When the tires hit the body of the car when the suspension is compressed. This happens when the car doesn’t have enough suspension to absorb the force of the bump it is traveling over. Bump-stops can prevent this by providing a cushion between the suspension and the frame that prevents the tire from moving up high enough to strike the body of the car, but if they are inadequate or missing then this problem can occur. Bottoming out can easily damage the body, wheels, or suspension system.
Why do my rear wheels get angled?
Poor alignment of the suspension can cause the wheels to be angled in a way that causes this issue. Oversteer: When the rear of the car loses traction and comes loose rounding a corner. If the body rolls too much cornering then the shift in weight may cause the rear wheels to lose traction.
What is the weight resting on the suspension called?
Weight resting on the suspension is called sprung weight. Having low unsprung weight compared to the sprung weight makes a car feel lighter and more lively. The opposite provides a harsh ride and a feeling of having less control of the vehicle. If the differential sending power to the wheels via the axles is attached to the frame or body ...
What happens when a car rolls too much?
All cars do this to some extent when going around a corner, but if the body of the car rolls too much then the shift in weight can cause the vehicle to spin, steer out of the turn prematurely, or lose traction on one or more wheels. Bottom Out: When the tires hit the body of the car when the suspension is compressed.
What is the purpose of a shock absorber?
Shock absorbers are oil-filled cylinders that force the suspension to compress and decompress at a consistent rate to prevent the springs from bouncing up and down.
