Wiper Production Recounted For Your Delectation.
The common wiper blades design is so brilliant that it has spread around the world like wild fire but regardless of where they are discovered they are nearly all assembled the same way. Most factories producing wiper blades get there bits from other contractors which are delivered and stored on the premises. These are all then bequeathed as required down to the factory floor and assembly line where cheap labour is abused to make giant profits. The atavistic wiper blades design was actuated by hand from inside the cars cab, times have now changed and today’s breed of wiper blades rely on electricity. Two major parts from sub contractors are therefore needed in order to construct a fully operational wiper blades appliance. These parts are an electric motor, a worm gear and a linkage system or technique to lock all these bits together.
The linkage system is the component which transfers movement of the electric motor into the action of the windscreen wipers across the screen. The worm gear is a strangely named device but gets its label from its appearance which looks like a straight bar which is threaded down its length by a helical structure. This worm gear comes with it the ability to multiply the output or torque of the electric motor by massive amounts and at the same time reducing the output by a huge volume. It is this component which makes the whole windscreen wipers assembly possible converting the output of the electric motor into stuff practical to power the windscreen wipers. This part is transferred to the linkage system which translated the windscreen wipers back and fourth in a constrained motion over the wind screen glass. When the windscreen wipers reaches it’s lowest position a simple electronic device senses this and shuts off the power to the windscreen wipers.
In this way the wipers are always stopped in the down position away from the windscreen so as not to block the driver’s precious vision. A cam shaft is then attached to the worm gear and this cog turns in time with the output of the electronic motor and the worm gear. The cam turns and is fastened to a shaft with is basically a long stick and as the cog or cam shaft rotates the long stick or rod is propelled forward and back. This rod is then switched to another which actuates the wipers part on the passenger side as well as the driver’s side. The wipers configuration itself has a few options, one it can be operated in tandem as described above or alternatively just a single unit wipers can be placed in the centre of the wind screen. The result of this enterprise will then undergo some form of quality control testing by a skilled professional who will make sure they are operating in ok parameters. These if successful can then be boxed up and sent to retail outlets and car makers, the waster from this enterprise can often be sold on again as scrap which is good news for the environment. Currently in this reviewers opinion the best type of wipers today are made from silicone and can be bought online for large discounts.
