Different Types of Windscreen Wipers and their Movements
As discussed in last month’s blog post, vehicle owners need to closely inspect their windscreen wipers for any tears and holes in the rubber as this can cause the vehicle to fail its MOT. Keeping your windscreen wipers in top working condition will ensure safety on the roads during treacherous conditions which can otherwise impair the driver’s line of vision.
Here’s 8 Windscreen Wiper Movements
Different types, makes and models of vehicles have different windscreen wiper configurations which means that there are a number of ways they can move. Take a look at the guide below to view the variety of ways windscreen wipers operate.
1. Pivot/radial – left hand drive
The blade for this windscreen wiper is secured to a single arm which is attached to the motor. It moves in a parallel motion and is most commonly found on left handed cars.
2. Pivot/radial – right hand drive
This is the mirror reverse of the first windscreen wiper and is mainly found on right handed cars.
3. Sequential sweep
The mechanism behind this type of windscreen wiper is far more complicated than other designs as the wipers move in opposite directions at the same time. This allows the blades to cover as much of the windscreen as possible, minimising the risk of a large unwiped corner on the front passenger side of the windscreen.
4. Single blade arm
Most commonly used on rear windscreens, this single windscreen wiper glides back and forth with a centre pivot to ensure as much coverage as possible.
Using cantilevers, this type of windscreen wiper is attached to a single arm which extends upwards to reach the top corners of the windscreen and glides in at each end and the middle of the windscreen to create an ‘M’ shape. Rather than using two wipers, the single blade allows for wider coverage, moving any excess streaks away from the centre of the windscreen and out of the driver’s line of vision.
6. Pantograph system
Used on commercial vehicles with larger windscreens, such as buses and coaches, pantograph systems feature two arms for each wiper blade. Supported by a vertical bar, one arm is attached to a motor and the other is on a pivot. This mechanism allows the blade to cover more of the windscreen with each and every gliding movement which is ideal for larger windscreens. It’s worth noting that when stationary, the wipers stay positioned in the middle of the windscreen which may cause the driver’s line of vision to become partially obstructed when not in use.
7. Dual windscreen wiper arms for two windscreens – pivoted at the top of the windscreen
Vehicles which feature two windscreens, such as US military wheeled vehicles, jeeps and utility vehicles, use dual wiper arms. These operate on a pivot from the top of the vehicle rather than the conventional way, allowing for better coverage towards the bottom of the windscreen.
8. Dual windscreen wiper arms for two windscreens – pivoted at the bottom of the windscreen
Most commonly found on older models of car with two front windscreens, such as the iconic Volkswagen ‘split screen’ camper van, this system uses a simple radial design. However, rather than operating on a pivot from the top of the vehicle like the windscreen wipers featured seventh in this list, they work in the conventional way; this allows for better coverage towards the top of the windscreen.
