Abstract The paper analyses the operating conditions of band-pad brakes drilling winch, materials and coatings for strengthening metal elements friction pairs. Methods researching thermal stress-strain state brake units are considered. problem development theoretical research properties new polymer with gradient production overlays improved operational characteristics is singled out. A mathemat...

Introduction . Road safety is largely determined by the technical condition of vehicle, and especially control systems. The braking system one them. To improve its efficiency, various assistive electronic systems are now widely used. These vehicle through wheel mechanisms. Brake pads a constituent element friction-type brake mechanism. efficiency depends on quality, regardless presence auxiliar...

By conducting an interview survey using actual driving videos, we found that normal drivers without the right of way have incorrect awareness of the potential hazards when entering a non-signalized intersection. We also conducted a questionnaire survey in which subjects answered a sequence of their driving behaviors concerning when and how they make safety checks and operate the accelerator and...
