Abstract: Preliminary aim is to design a Rack and Pinion Gearbox (RPG) which has desired steering ratio, zero play in the RPG and sensitive steering.The design of rack and pinion has been done by using CATIA software. Computer aided analysis (CAE) of RPG casing and clevis joint has been done so as to make sure they are safe. The newly designed RPG is compared withthe original equipment manufacturer (OEM) rack and pinion gearbox on the basis of cost, weight and the steeringgear ratio parameter. The results of the design shows that weight of new rack and pinion gearbox is 20% less than the OEM RPG with nearly 40% reduction in the cost achieving the desired steering ratio.

Keywords: Rack and Pinion Gearbox (RPG), CATIA, CAE, ATV, Baja, arm crossover.
