Influence of a Road Surface on a Motorcycle Braking Process

The most important aspect of constructions of vehicles is safety. In motorcycles, in contrast to cars is not common to use elements of passive safety which minimalize consequences of collision. Therefore the most important is to ensure the proper possibility to avoid crash that is the adequate level of active safety which is mostly the brake system. It is often assisted by the construction which prevents the wheels to block, however the majority of motorcycles are still not equipped in this kind of system. In order to determine the effectiveness of working of the brake system and its impact on motorcycle’s movement safety, it is necessary to focus on case of emergency braking, that is delaying, to full stop where important is to reach the maximal possible delay in the shortest period of time. Because of the changes in road surface, important is to be aware of releasing or stopping the motorcycle in different conditions. It permits us to react properly and avoid dangerous situations in case of noticing a surface with different adherence. The purpose of the research is to analyze changeability braking process depending on different surfaces on which the motorcycle is moving. The research was carried out on one motorcycle and four different surfaces, reflecting the conditions of every day use of vehicle. It was dry, wet and destroyed asphalt, and gravel surface. Comparing the value of delay, its process and stability in time, velocity of accumulation and way of braking obtained on different surfaces.
