Development of the drivetrain including brakes and wheels for the Formula SAE-A vehicle

Abstract

This project is part of the USQ Motorsport team entry in its first Formula SAE-A competition. The project aim is to design the drivetrain, brakes and wheels of the car which was the focus of developed in this project. The design must also be optimized to provide for a competitive racing car. The investigation into these areas starts with research into the possible systems available to be adapted to the racing car. The interfaces between each area of the racing car means working with other members of the team to decide on viable options is required. Teamwork is therefore essential for the success of the overall project to complete the construction and perform well at the Formula SAE-A competition. A design is developed for the drivetrain and detailed analysis of the design is conducted. The main component of the drivetrain is the centre shaft which is analysed to find the stresses and fatigue life. Associated components of the drivetrain such as rear sprocket, chain, bearings, half shafts and chain tensioner are also designed to complete the drivetrain assembly. The brakes and wheels have also started with background research followed by a detailed selection process to find the best option. Consideration is also required as to how all the components will fit together to provide a car that is well designed and has good performance characteristics. The finial construction and procurement of the components making up the drivetrain, brakes and wheels was on track for completion to enter the Formula SAE-A competition.
