Yea,its the raining season and we are all loving the cold weather, we no longer complain about the sun and how hot the weather can make us feel.

You must ensure that your car is in good shape this season.

There are lots of things you can do to make driving in the rain safer, including being prepared by making sure your car is ready and ensuring you can always see properly. But most importantly, you have to drive according to the conditions, and adjust a few of your habits to avoid sliding, skidding, or being involved in a collision.

Do you know how your car suspension works?

1.know how your  suspension system works.

For the most part, modern cars have independent suspension front and back, allowing each wheel to travel independently of the others. Some cars, though, use a more basic beam axle because of lower cost and simpler design. The only beam axles still seen being used in new cars are live axles. Live axles have powered wheel at each end and dead axles have free-spinning tires at each end. The problem with rear tires that don’t move independently is that they always keep the same angle relative to one-another rather than relative to the road surface. This means less traction and less predictability in the handling.

Beam axles also contribute unnecessary unsprung weight. Unsprung weight is weight that is not resting on the suspension. 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 of the car rather than the axle itself, then there is a significant amount less unsprung weight. This is one big reason, aside from the many other advantages to having one wheel able to move without greatly affecting the other wheels, why independent suspension is almost universally adopted by car makers for the front and rear wheels of their vehicles.

Independent front suspension allows each front wheel to travel up and down with the spring and shock absorber bolted to the frame on one end and a control arm or wishbone on the other end. A control arm is attached the front of the vehicle near the center at one end of the arm and the steering knuckle at the other. A wishbone does the same thing except it attaches to the frame at two points, causing the piece to resemble a wishbone. The positioning of every component in independent front suspension systems is very important as the front wheels have to steer and maintain consistent alignment to provide safe vehicle operation.

Independent rear suspension uses the same technology as the front without the consideration taken for the steering dynamics, as the rear wheels usually don’t steer. Rear-wheel and all-wheel drive cars have a differential mounted to the frame in the middle of the control arms or wishbones, while front-wheel drive cars have very simple rear suspension, needing only springs and shock absorbers.

Shock absorbers and springs provide all of the cushioning and compressing when the suspension moves. Springs provide force to hold the sprung weight up off of the wheels and to resist compressing. 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. Modern shock absorbers (or shocks) are velocity-sensitive, meaning they are smoother when dealing with light bumps and put up more resistance to big bumps. Think of the springs as guard dogs, ready to viciously defend the car from bumps. The shock absorbers would be the ones holding onto the leashes of the guard dogs, making sure that they don’t take the job too far and do more harm than good.

 

2.How does the suspension system increase passenger comfort?

When the ride or ride comfort of a car is good, it means that the suspension has good road isolation. The suspension is able to move up and down when needed without jarring the vehicle. Just enough feeling from the road reaches the driver, so they will know of any alarming road conditions and feel a rumble strip if they enter the shoulder of a high-speed road.

Older luxury cars have a reputation of having such cushy suspension that the driver would feel as if they were driving a boat. This is not optimal, as feeling the road (at least a little) is essential to keeping situational awareness while driving. Sports cars and factory-tuned compacts often are criticized for their poor road isolation. The manufacturers of these cars assume their demographic is looking for fast lap times at a track over road comfort. Also, vehicles traveling at racetrack-speed are getting a lot more down force from the air that could make comfortable highway-oriented suspension act unpredictably, especially when cornering.
