1.Power Doors and Windows: In Jurrasic Park, it was tough for Dr.Grant and Murphy kids to come out of the powered vehicles when the whole ectric system came down. Power Doors and Windows provides central locking facility plus comfort. In case you are stuck somewhere and you cannot pull down the windows because of electronic breakdown in the car, a short circuit due to rain/flooding, keep some iron tool handy to make your way out of the window pane. For mechanism, The picture will give some idea how it works.
2. Power Steering: Ever thought what will happen if while driving suddently the ignition went down, how hard can it become to steer these 2000 cc cars.
Easy Steps:
a. For precuaionary measures try this in some big vacant parking lot
b. keep the vehicle speed to 5-10miles/hr.
c. At this speed turn the gear into Neutral and swtich off the ignition of card. Remember that turning off means shutting down Power to all parts of car which run on motor/rotory power and not via battery .
Now steer your car, it really needs some muzzle power lol!
Now steer your car, it really needs some muzzle power lol!
There have not been much advances in the Car steering system in the last few decades other than intoruducing the Hydraulic system to the Steering Valve and Rack and Pinion arrangement and introducing a Speed sensing mechanical unit. In coming years, Automakers may altogether removethis mechanical Steering system with electronic motor controlled system thus gaining adavantages like
a. reduced noise
b.less mechanical units, so reduced wear and tear
c. more efficiency, more mileage
d. more control and than ofcouse digital storage of preferences, I mean, the way each member in the family can store his preferences for Car seat position and side plus back mrror settings , he can also set the strength level he finds comfortable for steering car.
3. Power Breaks: Ok, Power Breaks is one thing which will work even if there is electrical breakdown or car run out of gas, but then, only for a while.
Few interesting things:
a. When we take a turn both tires on the front axle move at different speed (and so likewise there rear counterparts): same axle gives two different speeds to tires on its sides, this is acheived via differential
b. More force is required for the front tires to stop them then the rear ones, as the front side has engine weight + weight movedahead due to sudden break
c. front wheel disc breaks are forced to come into play a little later than the rear wheel drum brakes to facilitate smoother breaking
