dc.description.abstractRack and pinion gears are used in small sized vehicles due to their small size, lightness and ease of repair to produce steering systems. The main purpose of this paper is to design and implement a rack and pinion steering system using Ackermann steering conditions, on a go kart, to aid in preventing carjacking. With the use of Solidworks, a virtual rack and pinion steering system is designed and simulated. Furthermore, the rack and pinion gears designed are 3D-printed and implemented onto an existing go-kart. Using Ackermann steering conditions, quantities such as the turning radius, Ackermann angle, outer and inner wheel angle, steering torque, etc. are calculated and practically tested on the go-kart. This is to help prevent the tyres on the go-kart from slipping when taking a turn. Additionally, a GPS tracking system and motors are installed onto the go-kart, with the motors being controlled via a mobile app. From simulation in Solidworks, it was shown that there were minimal contact stresses between the rack and pinion gears. It was observed that the structure would be void of failure as it had a factor of safety between 4.034 and 3.925×10)*. Lastly, from the practical verification of the Ackermann steering conditions calculated, all the angles measured with a protractor were similar. This verification demonstrated that the steering system designed adhered to the Ackermann steering conditions.en_US
