HOW DO WINDSCREEN WIPERS WORK?

The very first type of windscreen wiper dates back to about 1903 and were apparatus that needed to be manually operated.

Passengers were required to run a lever inside the automobile to move the wipers across the windscreen.

Luckily, technology has progressed to the stage where, now, wipers are all powered by electric motors and mechanical elements, and are standard on every vehicle.

On most cars, the wiper controls are on a stalk behind the steering wheel on the other side of your own indicators.

On some cars, the wipers are controlled by a circular control situated on the dash, which is usually on the side of the steering wheel (for right-hand drive cars).

Another increasingly common feature is wipers that are triggered by sensors in the windscreen of the vehicle, which regulates how quickly they go by sensing how much water is on the windscreen.

Pretty neat huh!

In any case, once the wipers have been switched on, the upcoming steps are usually the same across all models and makes.

An electric motor located directly beneath the wiper arms (typically underneath a bit of plastic trimming called a plenum, right in the front of the windscreen).

Once triggered, the motor transmits drive via the attached linkages and then begins to push and pull metal sticks which are joined to the base of the wiper arms.

The way this is designed signifies the metal rods essentially rotate in a circular movement and move back and on a very specific space.

This back and forth activity is what pushes and pulls your wiper arms round your windscreen.

There are a few kinds of windscreen wipers moves that may be seen on cars now.

Pivot

  • The pivot is the simplest form of windscreen wiper system.
  • This type of windscreen wiper includes two arms, with one mounted in the centre and mounted on the far right-hand side.
  • They move across your windscreen parallel to one another.

Sequential/Opposed

  • This movement also utilizes two arms.
  • When triggered, both arms sweep away in the other one until they get to the edge of their side of the windscreen.
  • The mechanics to work this type of windscreen wiper are somewhat more complex compared to pivot style.


This fashion only uses a single wiper arm that's mounted in the middle of the windscreen.
When triggered, it finishes a full half-circle across your windscreen.

They've a fantastic ability to expand towards the corners because the blade moves round the windscreen, raising its coverage.

This fashion of wiper arm is the most complicated and costly.
