The "clogging free" test bench concept for mud flaps used on buses and trucks to remove water and slush.

The paper presents the results of research on the developed mudguard system in trucks and buses with the "clogging free" function, allowing for the effective removal of snow and slush from the mud flap (apron). It has been shown that the obtained results constitute the achievement of product innovation on a global scale, as there are currently no solutions with documented functionality in this field globally. Innovative technology for the production of car mud flaps based on secondary raw materials (recycled) was developed, based on several modules, incl. a plastic extrusion module with a plasticizing section - forming sheets/a wide "web" of material, a module for creating a developed splash surface, and developing technology for producing projections - containing a cylinder in the form of a cylinder with several thousand protruding pins-pins. Recycled plastics were used for the production of the mud flap. Material recycling is currently one of the most effective methods of recycling, as it allows obtaining recycled plastics with favorable mechanical and usage properties while maintaining a relatively low energy expenditure. The results of the work show the positive impact of the solutions proposed by the authors on the environment, thanks to the use of recycled and reusable polymer recyclates in the polymer mixture used in the production of mud flaps greater than before. In summary, it has been proven that the designed system, in addition to meeting the water spray dispersion requirements compliant with all vehicles, is also equipped with anti-spray devices for snow and slush removal.
