Everything You Need To Know About Car Wiper Blades
What Is Wiper Blades?
The
debris, snow and rain deposited on vehicles' front window is removed by a
windscreen wiper or windshield wipers. Generally, all the motor vehicles that
include cars, trucks, buses, train locomotives and watercraft with a cabin and
some aircraft have one or more such wipers installed. These are generally a
legal requirement.
Usually,
a wiper contains a metal arm, one end pivots while the other end is equipped
with an elongated rubber blade connected to it. The arm is controlled using an
electric motor. Also, in some cases, pneumatic power is put to use for a number
of vehicles. You can observe the blade swinging back and forth over the glass,
pushing water, other precipitation, or any other contaminants to visibility,
from the surface. In the latest models, you can adjust the speed, with several
continuous speeds, and generally one or more intermittent settings. Almost all
the automobiles that are designed for personalized use have two synchronized
radial-type arms, on the other hand the commercial vehicles make use of one or
more pantograph arms.
In
a variety of vehicles, a windscreen/windshield washer system is used to enhance
and expand the function of the wiper(s) for dry or icy conditions. This system
performs the task of spraying water or an antifreeze window washer fluid at the
windscreen making use of a large number of well fit nozzles. This system aids
greatly in eliminating the dirt or dust from the windscreen in times when it is
used in concert with the wiper blades. The snow or ice can be removed with
antifreeze washer fluid. During such harsh winter conditions, various vehicles
have extra heaters that aim at the window or embedded heating wires in the
glass. These defroster systems aid to keep the snow and ice from building up on
the windscreen. Although rare, at times you are likely to find miniature wipers
on the headlights that assure optimal function.
Types Of Wiper Blades
In
all there are a variety of wiper
blades available that include the standard wiper blades,
spoiler wiper blades, flat wiper blades, flat wiper blade upgrades (or
retrofit). Parts Avatar has mentioned here about the types and usage of various
types of wiper blades so that it becomes easy for you to choose the most apt
wiper for your vehicle:
- The
Standard Type Wiper Blades - These types of wiper blades
of windscreen wiper are the conventional ones. They are famous for looking like
a coat hanger and can still be found on a large number of new vehicles,
although this is declining day by day. These wiper blades are connected to the
vehicle using a hook shape wiper arm fitting. Usually, the sizes range from
10" to 28". Commonly, you are likely to notice different sizes fitted
to the drivers and passengers’ sides of the windscreen.
- Spoiler
Type Wiper Blades - The spoiler type wiper blades have a full
spoiler that runs throughout the length of the blade that helps greatly in
keeping the blades closer to the windscreen at higher speeds. This can be found
mostly on the driver’ side only. They too are connected to the vehicle using a
hook shaped wiper arm fitting.
- Retrofit
Flat Wiper Blade Upgrade - These types of wiper blades are made with
new style and technology and are gaining popularity. They do not have a metal
'coat hanger' shaped frame but rather have a tensioned metal strip running
within the rubber frame of the wiper blade. Such structure enables design a
flatter aerodynamic shape that helps in decreasing the noise made by the wind.
The internal metal strip present inside puts constant pressure along the length
of the blade and has a built-in spoiler. This type of wiper blade is smaller
than a conventional wiper. This kind of wiper blade helps in providing less
obstruction to the driver's field of vision.
- Hybrid
Wiper Blades - The hybrid wiper blades have an aerodynamic
shape i.e. it has a flat blade with the solid construction of a classic wiper.
The ‘aerodynamic skin’ of the wiper blade is composed of an articulated plastic
frame. This helps greatly in smoother airflow that further helps in creating an
even down force throughout the length of the blade. For support in the rubber
wiping element, you can find steel substructure under the skin. This type of
design enables the complete wiper to flex according to the shape of the
windscreen, thereby creating a smooth and efficient wiping action.
- Flat
Wiper Blades - These types of wiper blades conform to the
newer style and technology and are rapidly being used in all the vehicles. They
too don't have a metal ‘coat hanger’ shaped frame, but rather have a tensioned
metal strip that runs throughout within the rubber structure of the wiper
blade. This design has a flatter aerodynamic shape that enhances the
performance by reducing wind noise. Constant pressure is being applied by the
internal metal strip present throughout the length of the blade. It also has a
spoiler built inside it. The flat wiper blades are smaller in size; hence they
provide little obstruction and disturbance to the drivers' field of vision. In
case, your car had these type of wiper blades, note that you can change these
only with similar type of flat blades. Side pin, pinch tab, push button and
slider are a few generic types of wiper arm fittings.
- Specific
Fit Wiper Blades - This type of wiper blades are generally
original equipment replacements and are designed for certain vehicles. A number
of rear blades have uncommon designs and should be changed with this type of
wiper blade only.
- Rubber
Refills - The rubber refills only have the rubber part of the wiper
blade and are designed in such a way to replace the present rubber element. Its
replacement is cheap as you can perform the replacement by solely replacing the
refill. Well, we advise you to replace the complete blade for better
performance. Avoid changing the refill too many times as it can weaken the
wiper blade superstructure. Note that these refills can’t be utilized to refill
the new variety of flat wiper blades.
How Does Wiper Blades Works?
The
wiper blades serve the purpose of cleaning the windshield screen. Operated by
an electric motor, you can find this motor connected to the worm gear that
transfers the required force to move the wipers as fast as the desired
movement. The worm gear aids in creating the force that is essential to move
the wipers. These arms help in the movement of the actual windshield wiper
blades. These blades are composed of rubber. Adequate amount of pressure is
required by the windshield in order to eliminate all moisture without any
streaks. In the middle of each wiper blade, you can find the arms connected.
Each wiper blade has numerous arms that evenly distribute the pressure onto the
windshield. This entire procedure is referred to as tandem system. A number of
times, there are other systems used too that include the single arm system
(found in Mercedes vehicles). In this, there is a single arm (controlled)
system that extends and retracts as it moves along with the opposed system that
has pivot points on opposite ends of the windshield with the wipers moving in
the opposite direction. These windshield wipers function at varying speeds.
Frequent Problems With Wiper Blades
There
are a number of
problems with the wiper blades that might be faced:
- Water
smearing in both directions - Damaged or dirty blades, bad
quality wiper fluid or polluted windshield can lead to this problem. Firstly,
we advise you to clean the windshield and blades using lukewarm water. Next,
wipe it using a microfiber towel soaked in rubbing alcohol. Replace the fluid
if your problem remains unsolved. Finally, replace the blades if you want to
avoid streaks on the glass.
- Blades
are not synchronized - This is a minor problem and is quite
uncommon. The wiper blades are designed in a way that they rotate in rhythm to
be able to clear all the water, dirt and snow off the screen. When at times,
these fail to function in synchronicity, it is indicative of a loose arm or a
damaged linkage. For this, tightening a screw or mending the exhausted linkage
is a common and effective solution.
- Crushing
sound created by the wiper - This is likely to happen when
the blade arm is fixed too tightly onto the linkage. It leads the gears in the
blade motor to scrape. Consequently, unusual noise is created. Don’t leave the
problem unchecked as it might lead to burning the motor completely.
- You
are likely to encounter a clattering noise - This happens due to
grease, wax and oil deposits on the glass and the blades. Due to this, the
wipers fail to perform their function and also lead to marks. Give your
windshield and blades proper attention and regular service, if you want to
avoid such issues.
Symptoms Of Bad Wiper Blades
For
effective and safer operations of any vehicle, apt working of the windshield wiper
is important. These tend to wear out after a certain duration of time as they
are made out of soft rubber. Regardless of their usage, we advise you to
replace them every six months. In all, there are a large number of wiper blades
with different ways of replacements. Usually, almost all vehicle owners change
the complete blade that is connected to the wiper control arm, while on the
other hand, some people change the soft blade insert. So, no matter what method
you choose to adopt, it is important to replace the wiper blades, once you
notice the following symptoms:
- You
are likely to notice streaking on the glass - well, wiper blades are
designed in such a way that they evenly press onto the windshield and eliminate
water, dirt and other contaminants smoothly from the glass. Due to smooth
operations, there usually aren’t any streaks. Although, if the windshield wiper
blades get old and wear out, you will notice streaks and spots on the glass. We
advise you to perform immediate replacements if you see any such kind of
streaks or spots on the glass of your vehicle.
- You
will hear screeching sound when the wipers operate - if in
case your wiper blades have outlived their span of operations, you will hear
screeching sounds that are mostly triggered by uneven rubber gliding over the
windshield. Often, these sounds are heard when the hard rubber shrinks because
of excessive heat and sunlight. We advise you to perform amendments as these
types of issues not only lead to screeching sounds but also can end up
scratching your glass screen as well.
- Wiper
blades might bounce as they function - there will be times when you
might turn on the wiper blades and you’ll see them bouncing while operating. If
you encounter this, take it as a warning sign for damaged wiper blades. Bent
wiper blades usually cause such problems. Check thoroughly or take professional
advice before jumping on any fixed conclusions regarding the complete
replacements. Perform a thorough inspection of both the wiper blades and
windshield wiper blades.
Parts Avatar Canada recommends you to perform replacements of the wiper blades at regular intervals in order to avoid such type of problems. You can also buy new wiper blades and get them installed at the same time as performing a complete oil change. Also, you can get them change occasionally with change in seasons. For example: for cold weather climates specially coated and covered wiper blades that protect from ice freezing on the blades.
