A two wheeled vehicle such as bicycle and motorcycle tilt in the turn to counter the centrifugal forces acting on the vehicle, while other vehicles including three wheeler, motorcar and quad bike rolls slightly out of the turn. This increases load on outer wheels and limits the velocity of turning of vehicle.

The goal of this project is to design and fabricate a three wheeled vehicle consisting of one front wheel and two rear wheels also called as the delta tricycle. Tilting a vehicle can provide many performance and design advantages including greater stability while turning, reduced load transfer to outer wheels as well as reduced probability of rollover while taking a turn. A tilting tricycle tilts towards the centre of curvature of the turn while retaining a vertical position when going straight. The tilting effect is actuated with the help of suspension springs mounted on rear wheels supported by respective wheel arms of the delta tricycle. This tilting action of tricycle results in achieving higher velocity while turning in comparison to rigid frame tricycle. Moreover with shift in centre of gravity towards centre of the turn while tilting, radius of turning is reduced with greater stability of vehicle.

After conducting study of various tricycles and recumbent tricycles present and going through their pros and cons the final conclusion is extracted to design and fabricate a tricycle that offers ease in ride, ergonomic comfort and of future importance. The final tilting trike consists of designing of main chassis for carrying a driver supported by three wheels mounted on the same chassis, the sub frame supports the two rear wheels that can lean or tilt with respect to steering. The design of the vehicle is prepared using CAD modelling software Solidworks2013 and static force analysis is done using FEA software ANSYS14.5.
