What is a crumple zone on a car for?
The crumple zone, also known as the crash zone, is the place in an automobile where the energy of the impact is absorbed and reduced, thus preventing it from being transmitted to the occupants and keeping passengers safe during injury. It’s designed to crumple and deform in time of collision.
How does a crumple zone work?
If your car is moving at speed and then collides with another car or object, you and your passengers will continue to move forward within the car due to inertia. Because of gravity, you will hit the steering wheel or dashboard with a force greater than your automobile safety normal weight.
- The force will increase depending on the speed you are travelling at.
- A crumple zone is meant to slow down the crash, and also absorb energy to decrease the difference between the rate of the car occupants (still travelling at speed because of momentum) and the car (abruptly halted.)
- In effect, some parts of cars have been”sacrificed” — designed to literally crumple on impact, leaving the good cabin intact.
- Impact energy that affects the reinforced cabin area is going to be distributed over a larger area.
- This reduces the damaging affects of accidents on passengers and drivers.
Basically — you were travelling at 60 mph, now your car is going at 0 mph but your body is still going at 60 mph. Whatever you can Auto Services Edmonton do to slow yourself down will ultimately reduce any damage.
Does it save lives?
Like seat belts and air bags, a crumple zone slows down the passengers and driver to stop them hitting the windscreen at speed and with greater force. The force of this impact can be greatly reduced even with a slight decrease in deceleration.
Of course, a vehicle colliding with a good car without a crumple zone will absorb most of the energy and really damage of the crash. The same would be true if it collided with a solid concrete wall. However, two automobiles without crumple zones colliding would be pretty disastrous — so it’s always better to be in a car with a crumple zone!
Why do cars have crumple zones?
The term”crumple zone” likely sounds confusing. As if there are places in your car designated Edmonton Auto Repair to cave in on effect. Well, that’s not exactly how it functions. Looking into why cars have crumple zones, you will quickly realize that engineers look at security in terms of how to keep the occupants safe, and part of that is considering how the body of the car can best absorb impact in case of a collision.
Every car has a security shell meant to protect those inside. Crumple zones, which are made to consume impact 2019 Volkswagen Jetta driving on road and direct it away from the occupants, are located at the front and back. They do crumple because this allows for the force to be spread out. The energy from a crash is then sent across the front end, by way of instance, rather than all of the force being placed directly at the impact site. The zones are developed to break down a predictable pattern.
An occupant cell, on the other autobody saskatoon hand, is rigid and designed so it will not crush on impact and will keep occupants safe as far as you can.
Saying the overall interior won’t crumple is not the same as stating the pedals will not. Or rather, they detach. Because legs and feet are prone to injury, pedals will disconnect at a particular degree of force to protect legs and feet from getting the pedals embed in them, as they would if they remained stiff structures.
Another key safety feature is the roll-over bar system, as the roof is one place that’s not supposed to crumple. Sensors on your VW monitor for the odds of a rollover and if the system is triggered, rollover bars in the rear headrests are released within 250 milliseconds to help fortify the roof.
