Windscreen wiper systems for commercial vehicles

We design and develop windshield wiper systems for the relatively small, straight windshields of military vehicles – for both protected and unprotected variants. We offer submersible wiper motors with protection class IP x7, which also comply with NATO interference suppression guidelines (DEF STAN 59, MIL STD 461, MIL STD 1275).

We design and supply wiper and washer systems, steering column switches, toggle switches, rotary switches, electric servomotors and stepper motors, as well as linear actuators for agricultural vehicles. Special consideration is given to application-specific requirements such as IP rating, abrasion resistance, climatic conditions, durability, and contact with corrosive liquids. Our portfolio of agricultural solutions includes tractors, farm loaders, combine harvesters, forage harvesters, crop protection vehicles, automatic feeders, and cleaning systems for livestock.

We design and supply wiper and washer systems as well as steering column switches and toggle switches for construction vehicles, paying particular attention to application-specific requirements such as IP rating, abrasion resistance, climatic conditions, and durability. We have special solutions for wheel loaders, backhoe loaders, telescopic handlers, skid steer loaders, excavators, asphalt pavers, construction site dumpers, graders, bulldozers, front dumpers, and cranes.

We develop and supply tailor-made solutions in the areas of wiper and washer technology, steering column switches, toggle switches, and rotary switches for both coaches and local public transport buses. Our solutions include robust and durable butterfly systems, parallel systems, synchronized single-arm and parallel-arm systems, and stand-up systems. On request, we can equip each system with our exclusive Aquablade technology. Steering column switches for turn signals, retarders, wipers/washers, and lighting, specially adapted to the requirements of buses, round out our portfolio.

Pantographs consist of a wiper system with a double arm, in which both individual arms are driven together. The arms are connected by a rider, achieving a very straight wipe pattern. Pantographs are particularly suitable for tall, narrow windows and are standard in most rail vehicles.

Parallel wiper systems consist of two individual arms that are driven simultaneously by a single motor. Parallel systems are used on vehicle windows that are wider than they are tall and where the driver’s side has a larger field of vision than the passenger side.

Single systems consist of only one wiper arm with a wiper blade. This system is particularly suitable for smaller windows or in very confined spaces. A single system allows for large wiping angles.

If the window is very flat and very wide, as is the case with many trucks, for example, a triple system is often used. All three arms move simultaneously, as in a parallel system, and are driven by a single motor.

Butterfly systems consist of two individual arms. The movement of the motor is transmitted via levers, rods, and a triangular plate to produce a counter-rotating movement of the wiper arms, with one of the arms reacting slightly delayed to prevent the arms from colliding. This system is mainly used for large, relatively flat windshields, such as those found on buses.
