ABSTRACT
The article presents the concept of a new friction surface of the brake disc with holes made along the Archimedes spiral. In the brake technology we can meet brake discs with a friction surface that is perforated in a different way. It can be a perforation on the friction surface using holes, cuts, holes and combinations thereof. Despite the many advantages of such disks, the modification of the friction surface increases the wear of the friction material. In the newly designed shield, only one cut was made on the disc radius, which was converted into a series of holes arranged in the Archimedes spiral line beginning at the inner radius of the target and ending on the outer radius of the target forming only one scroll. For such a developed concept of friction surface, numerical simulations were carried out referring to a smooth disc without perforation in the scope of determining the temperature rise characteristics as a function of braking time, distribution of reduced stresses and disc deformation. Then, after carrying out a prototype disc with Archimedes spiral drillings there was carried out bench testing of it and of a perforated disk. On this basis, the type of braking at which the drilled disc was characterized by better frictional characteristics against the smooth disc without perforation was determined.
