Newton’s 3rd law: For every action, there is an equivalent and opposite reaction. When the vehicle speed increases equivalent and opposite reaction is Wind resistance also increases. So creating wind resistances is the best way to stop the vehicle. But in cause of foundational brake system, pressure needs to be developed for braking.
When the emergency braking situation comes, people get panic to control the vehicle to avoid the accident. But unlikely we should not able to control the vehicle (refer Fig 1 to 5 without wind catcher). Why because all our primary, secondary, parking brake system depends upon surface contact between tyer and road. Even ABS/ESP can’t able to prevent the above situation. We have air bags to save us from accident, but don’t have any emergency brake system to keep away from accident.
Panic braking causes mass transfer from rear to front, means people in the vehicle pushed towards front, this may cause some injury/pain leads to death (mostly driver/co- driver). Preventing the vehicle lifting is also important.
Let’s see how wind brake operated by electromagnet works and integration with vehicle (refer Fig 6).
Electro magnet is placed over the vehicle top and metal plate is fitted into the wind catcher, which will revolute about hinge axis and maximum angle is controlled by angle controller. While normal driving condition wind catcher metal plate attached with electromagnet, at time of hard braking electromagnet demagnetize and wind lifts the wind catcher create wind resistances to stop the vehicle. Once the brake pedal return to the original position electromagnet magnetize and wind catcher metal plate attached with electromagnet.
When the vehicle speed increases, the wind flow opposite to the vehicle direction is also increases. So creating wind resistances is an equivalent and opposite reaction. But in cause of foundational brake system, pressure needs to be developed for braking.
It is possible to integrate with most of the existing vehicle with minimal modification without affecting the primary brake system.
Due to the above arrangement, life of the tyre and other drive train component will increase.
