I denna rapport redovisas fyra koncept för utveckling av en bromspedal, med målet att reducera godstjockleken från den befintliga pedalen som är 2mm till 1,5mm, men samtidigt behålla hållfastheten som den befintliga bromspedalen erhåller. Det ställs höga belastningskrav på bromspedaler, och att minska godstjockleken innebär högre påfrestningar på materialet.För att utveckla en ny konstruktion som skall leva upp till dessa krav har programvaran PTC Creo 3.0 använts, och för analysering av dessa koncept har verktyget Simulate använts.I resultatdelen simuleras och redovisas fyra koncept i 1,5mm plåt som jämförs i total förskjutning med originalpedalen i 2mm plåt. Slutsatsen är att de inte når upp till lika bra resultat som originalpedalen. Däremot med 1,9mm plåt når det resultatmässigt bästa konceptet (koncept 3) upp till ett bättre resultat än originalpedalen, och detta leder till en viss förbättring i minskning av material, med bibehållen hållfasthet. / This report describes four prototypes for the development of a brake pedal, with the goal of reducing material thickness from the the existing pedal from 2mm to 1.5mm, while maintaining the strength of the existing brake pedal. There are high load demands on the brake pedals, and to reduce the thickness means higher strain on the material.To develop a new design that will live up to these requirements, the design tool software PTC Creo 3.0 has been used, and the analysis of these structures has been performed using the tool Simulate in PTC Creo parametric.The result show four concepts presented and simulated in 1.5mm plate thickness, and the results are compared with the original pedal results in 2mm plate thickness regarding total displacement. The conclusion is that the concepts do not fulfill the load requirements.However with 1.9mm plate thickness, our best concept (concept 3) is fulfilling the loading requirements even better than the existing pedal, and that leads to an improvement regarding reducement of material, with retained strength.

New technology in the automotive industry is the key to success. Therefore, it is appreciated when people come with new design ways to solve problems. This leads to innovation in the automotive industry that will lead to better and more environmentally friendly cars. This report presents a concept on a pushing counter lever spring which provides the same characteristics of force curve as a diaphragm spring in a pressure plate of a car has. The mechanism is to be used for long-term testing and evaluating clutch pedals. The work describes the development process and the manufacture of a prototype. The program Creo (CAD / 3D) is largely used to construct the components. As are the subprograms Mechanism Design and Simulate to simulate the movement and loads. Excel is a great help at the theoretical calculation of the mechanism and to evaluate the theory behind the concept. The result shows how to simulate a diaphragm spring in the pressure plate in a car for long-term testing of clutch pedals. The goal is to accurately mimic the force curve of a diaphragm spring, in order to design better pedals, and thus reduce the weight on the pedals to in turn reduce fuel consumption to protect the environment is one of the most important factors of all in the automotive industry.
