Redesign of Drive Shaft`s tripod Assembly, to improve the performance & reduce failure

Abstract

The aim of the project is to enhance the performance of the drive shafts tripod assembly to reduce failure and to increase the performance of the product. Drive shaft transfer the engine power to the wheels and it allows for steering and suspension movement and reduce vibration for the driver. Loss of drive in the vehicle due to inboard / Tripod assembly damage (Drive shaft inboard joint failure). Reducing the Failure of drive shaft improves performance and warranty life for both existing product and new product. Even though the interconnecting shaft was intentionally made for fail during excessive loading, unfortunately the inboard joint fractures during static testing and on field. The failure due to the inboard joint (Tripod assembly roller damage) is high. Objective is to find the Root cause for tripod assembly Failure, by the Adams simulation case study, It has been observed bottom needle only getting loaded with the maximum load of 27KN and to improve the static load test load has to be uniformly distributed or roller and Needle geometry has to be improved to withstand the load. The aim of the project is to design and develop a tripod assembly withstand Minimum 1600 Nm. design.
