Abstract (Croatian)

Nakon određenog vremena korištenja, žbice u žbičanim motociklističkim naplatcima izgube potrebnu napetost, što uzrokuje radijalno odstupanje obruča u odnosu na idealnu kružnicu, čega su posljedice narušene vozne osobine, vibracije prilikom vožnje i veća potrošnja goriva. Zadatak ovog diplomskog rada je bio razviti uređaj koji će olakšati i ubrzati ožbičenje motociklističkih naplataka. Pritom treba voditi računa da uređaj bude financijski prihvatljiv za manje radionice. U okviru rada najprije je provedena analiza postojećih rješenja na tržištu te je definirana lista zahtjeva korisnika iz kojih je kreirana tehnička specifikacija za razvoj naprave. U fazi koncipiranja kreirana je funkcijska dekompozicija na temelju koje je napravljena morfološka matrica s mogućim rješenjima. Temeljem parcijalnih rješenja u morfološkoj matrici, generirana su tri koncepta. Temeljem tehničko-ekonomskog vrednovanja koncepata odabrano je rješenje koje je bilo konstrukcijski razrađeno, napravljeni su potrebni proračuni, te je kreiran računalni model uređaja u programskom paketu Creo Elements Pro Schools Edition, sa svom dokumentacijom potrebnom za izradu naprave.

Abstract

After a certain time of use, the spokes in spoked motorcycle wheels lose the necessary tension, causing radial runout of the rim compared to the ideal circle, and the consequences are degraded driving performance, vibration while driving and higher fuel consumption. The aim of this thesis was to develop a device that will facilitate and accelerate process of tightening spokes on motorcycle wheels. One should not forget that the device is costeffective for smaller workshops. Within this thesis, first it was conducted the analysis of the existing solutions on the market and defined the list of user requirements from which is created technical specifications for the development of the device. Functional decomposition on which basis is made morphological matrix with possible solutions was created at the stage of conception. Based on partial solutions in the morphological matrix, it was generated three concepts. Based on the technical and economic evaluation of concepts, it was selected a solution that was structurally elaborate, made the necessary calculations, and has created a computer model with the software package Creo Elements Pro Schools Edition, with all the documents necessary for making devices.
