DUAL STEERED THREE WHEELER FOR DIFFERENTLY ABLED PEOPLE

Abstract

Transportation has become an integral part of people’s everyday life. At certain times, in large countries like India, people are forced to travel more than 200 km from their work place to their place of residence. People with disabilities in limbs have difficulties in travelling and cannot travel these long distances. They use devices such as wheel chair, crutches, and artificial limbs for mobility. These however cannot be used for long distance outdoor transportation. Therefore, the aim of this study is to design and fabricate a 3 wheeler with dual steering system for people with locomotive disabilities and armless people. A greater steering effort is required in the case of a four wheeler compared to a three wheeler. Hence, a three wheeler was selected instead of a four wheeler. In this case, handle bar steering system and leg steering system can be individually steered with hands and legs respectively, enabling its utility people with disabilities in limbs. Sprocket chain system was used in leg steering system. A 98cc Kinetic Honda Engine was used as the power source and the engine was placed towards the rear end of the vehicle. Single Rated and double rated suspension spring was used in the front and rear drive shaft respectively. Sprocket chain system was used in leg steering system. Furthermore, the driver sprocket and the driven sprocket was analysed for the design load using ANSYS.
