Abstract
Cilj ovog završnog rada je bio provesti konstrukciju hidrauličke disk kočnice na cestovnom biciklu. Kako je ona kompleksna i tehnološki napredna konstrukcija bilo je potrebno uzeti u obzir mnogo aspekata tehničkih znanosti i parametara kako bi se ispravno odredili ulazni podaci za proračun kao što su npr. brzina gibanja, ukupna masa, vrijeme zaustavljanja i faktori trenja. Znajući te parametre kao i uvjete kojima je izložena kočnica proveden je proračun ključnih dijelova i opis... More konstruiranja čime su dobiveni rezultati prihvatljivih dimenzija, materijala izrade kao i njihovih svojstava te ostalih karakteristika. Rezultati idu u prilog tomu da je optimalno rješenje kočnica vrlo male mase, aerodinamičnog izgleda, visoke čvrstoće i krutosti koja ima veliku sposobnost odvođenja topline. Takve uvjete zadovoljavaju M5 montažni vijci, zakovice od nehrđajućeg čelika promjera 2,4 mm, disk vanjskog promjera 160 mm i debljine 1,5 mm izrađen od jednog aluminijskog sloja i dva sloja nehrđajućeg čelika. Drugi vitalan aspekt konstruiranja kočionog sustava su oblik i dizajn koji čim više nastoje smanjiti djelujuće sile na disk i kočnicu pametnom geometrijom, odabirom materijala i sustavom odvođenja topline. Kako bi bio zadovoljen što veći broj utjecajnih faktora uzima se u obzir dinamika gibanja i kočenja što ukazuje na važnost prednje kočnice povrh stražnje te utječe na njezine dimenzije i snagu. Ovi i svi ostali rezultati potvrđuju zagovaran obim procesa konstruiranja hidrauličkih disk kočnica te dokazuju velik broj različitih konstrukcijskih rješenja. Less
Abstract (english)
The goal of this final thesis was to construct a hydraulic disc brake system on a road bike. As it is a complex and technologically advanced system it was crucial to consider plenty of technical aspects as well as relevant factors for proper estimation of beginning variables such as velocity, total mass, stopping time and friction factors. Knowing such factors and other driving conditions it was possible to make a calculation of the key elements and the description of all of... More them. In doing so, the results of optimal dimensions, best materials and their properties were gotten. They speak for themselves showing the best possible solution for a hydraulic disk brake construction which is a brake with the lowest possible mass, aerodynamic shape and high strength as well as the stiffness altogether with high degree of heat dissipation. In such conditions M5 bolts are commonly used for disc mounting, stainless steel rivets with diameter of 2,4 mm have shown to be more than enough to withstand the stress, Main disc dimensions are 160 mm which is the outer diameter and 1,5 mm of thickness made out of middle aluminium layer and two thicker stainless steel layers. Another vital aspect of construction is the geometry that needs to be made in such a way to minimize the inevitable forces acting upon it. Materials and heat dissipating system are also able to minimize them. For further precision of calculations, even more factors need to be considered. Dynamics is one of the most important ones that shows the importance of front brake over the rear which dictates the difference in disc dimensions as well as the power on the rear brake. These and all other results strongly indicate the complexity of constructing hydraulic disc brakes on a road bike and show the variety of different optimal solutions. Less
