Design And Fabrication Of Wheelchair Cum Tricycle For Physically Challenged And Elder People

This paper is about the development of traditional manual operated wheelchair cum tricycle is rear wheel drive in which chain drive mechanism replaced with single slider drive mechanism. The design concept of this model is taken from manually operated tricycle and railroad car. This wheelchair cum tricycle is useful for handicapped person. This modified tricycle gives the both advantages of wheelchair (for short distance or in-door use) as well as tricycle (for long distance use) in one machine. The transmission power and motion takes place from steering bar to rear wheel through linkages and rotating disc. Modification of this tricycle by single slider drive mechanism is used to transmit power that make the tricycle faster at fewer efforts as compared to existing tricycle. This paper provides the details of components used & designing parameters takes in consideration while designing tricycle. This wheelchair cum tricycle is very efficiently design and can be proved as better replacement for tricycle having chain drive mechanism.
