You
could fix it but for
when you think
you can serve it out you can actually give it a right not a chance on you Chevrolet
right smooth
and gives more around comfort than any call we have a home that's right that's why
we bought it but I can't imagine what they've done to make it
that way for lots of things things you can't see getting back.
Now you take that easy.
During I well know I remember me right now I want to hear engineering fans even
you can understand this years ago.
We always had a solid front facts
when one wheel went over a plant.
The other way Obama took the steering wheel jerked
and passengers rocked
and Joan then they figured out how to suspend the wheel separately.
Something like this with the wheels on separate axles they can't pass pumps to each
other so bonds have less effect on steering power Chevrolets have had
that kind of front wheel suspension for a long time
but the engineers still want satisfied with the steering.
You see the front wheels are connected to the steering by what they call tie rods
and because the steering wheel is over on the left side one tie rod was longer than
the other it was like well imagine trying to steer a rowboat with one
or longer than the other with
or to an equal length you would have to pull hard on the short order to get the
same steering effect as an easier pull on the long haul.
Here's what happens in the automobile to steal the wheels you have to push the tie
rods and remembering the robot you can see
that you don't have to move the tie rods different distances to get the same
steering results.
Also as the front wheels bump up
and down the tie rods turn them slightly both wheels turn inward
but because of the unequal tie rod one wheel often turns more than the other.
So
when straight ahead driving on rough roads unequal tie rods can make a cop force likely
to one side. Good heavens. No. And a difficult engineering problem to boot.
But if the tie rods were practically equal length each would move the same distance
to get the same steering result. And bumps would have an equal effect on the wheel.
Yes there were a lot of problems involved in designing such a system
but we have it on our new Chevrolet the tie rods are now practically equal in line
and they're connected to the steering wheel to a third arm called an idle rod this
even Valentino the steering system makes it less work to steer
and we get practically no road shock through the steering wheel.
No we'll fight
that center point staring what makes our new Chevy seem to sense where you want to
go with the same that's a good name for it.
Say waking up with air on the teeter totter do you think Kathy is alright.
She's in the best spot they bounce hard to get a smooth ride and
that very same idea is one reason for the smooth ride we get in the new Chevrolet
cart idea. Well a car accident like a teeter totter
when you drive over bumps it rocks up
and down in some cars the back seat is over the real
wheels where passengers bump up
and down like the kids on the end of the teeter totter.
In a new car the seats are Pertwee in the wheels where you get the smoothest ride
like Kathy at the center point of the teeter totter with set
of points eating all passengers get a front seat ride
but Centrepoint seating is just one of the reasons why our new car rides so
comfortably. Another reason is what they did with a real spring.
Well this will take some pretending but just a.
This chain is a rear spring
and the flashlight is a gadget called a shackle shackle a kind of pivot the spring
a surprise into the frame at the front shackle at the rear
when a bump pushes the wheel up shackle in spring act to cushion the shock.
Now with ordinary Springs
and shackles one passenger in the car gets quite a jolt from each Palm Springs a
two step.
However three passengers get a pretty good ride five passengers can hit bottom.
This spring is too stiff polite loads to software heavy loads.
Finding a spring system
that will give the same smooth ride regardless of the number of passengers
but they finally found a solution part of it was time in the shackles so the angle
between the shackle in the spring was much wider then they put in a softer spring
to give the single passenger a comfortable ride with heavy loads the shackle
moves back stretching the spring to stiffen it the more passengers the father the
spring is stretched and the stiffer it gets to cushion the heavier load
and that's our new Chevy softer Reus Springs where the shackle designed to give
just the right spring tension for a comfortable ride.
Whether it's carrying one passenger five.
So that's why they cart seen through ride the same way then driving along with the
whole family. That's right. But there's even more to our new Chevy's riding AIDS.
Next time we go to the airport watch the landing gear while an airplane lands
and notice how the shock absorbers question the tremendous weight of the plane as
it hits the ground the action of the shock absorber piston sliding into an oil
field cylinder absorbs much of the shock.
Let's make a model where you use this for the piston
and this for the cylinder with water instead of the oil.
Now one above pushes the piston Oh I forgot something.
These homes represent the valves in a real shock absorber which control the fluid
flow
when the piston is pushed down they permit the piston to slide down the cylinder
but slowly on the rebound the spring pushes the piston up
and again the flow which controls the action our Chevrolet shock absorbers are now
this same type
when we hit a bump They smother the shock by slowing down its effect.
One of these direct double acting shock absorbers is mounted in each front
suspension unit teamed up with the strong coil springs in the rear the same kind of
shock absorbers are placed diagonally instead of straight up
and down this is so they'll act like a braces on the swing the kids are using a
study the body of a car on curves and in cross wind driving.
So you see there are three big reasons why our new Chevy right so much easier.
The center point seating the new spring and shackle arrangement
and the new airplane type shock absorbers you never think simple things like
that can make so much difference.
Simple she says they seem simple after they have affected
but what it takes to develop one of those simple things and make sure
that it works. Why do you want to run. Don't you think Tommy Greendale too high.
Oh she knows how to hang on you.
Knows a better way to stir up a breeze read me along in our new car
but you've got something there.
You know they call it the car the green up front under the hood are two air
intake scoops lead into the passenger compartment.
When the car is in motion outside air is forced inside the amount of air admitted
can be controlled by events which open
or closed so you can have air from both schools from one. Well from the vid.
Another thing the air tunnels are signed up for to help keep out dirt and water
and screens
and baffles make doubly sure only air can get through outside it also passes right
through the heater core. So
when the heater is on the air is warmed as it's forced into the car
and over the front seats into the rear compartment.
Also the tunnels beneath the front seats off
and circulation to ensure uniform temperature front
and rear they blow up builds up enough pressure to force stale air out as well as
keep cold air from leaking in the heat it controls regulate the temperature of the
air and the speed of the blower. For instance in warm rainy weather.
You can turn the heat off entirely turn the blower on
and fill the car with cool outside air our defroster is controlled just as easily
with the wide defroster slots beneath the windshield ice demon fog melted away more
rapidly than I ever thought possible.
Yes From the standpoint of passenger comfort and a smooth riding
and driving age I think we've got a pretty good buy.
Well I'm set aside
and I'm not too easily pleased as you may have noticed I don't I know of course
we've just talked about a few of the many things
that a Chevy my number one choice like
that your dad's conception of a new Chevrolet yeah son.
It's the only way I could think of to show your mom the hidden values in our car.
So when we get going.
She'll know some of the reasons why we get all
that big car performance from our new Chevrolet.
