Design And Development Of Double Acting Friction (TAF) Transmission System Using Half Toroidal CVT

A continuously variable transmission (CVT) is a usual transmission that can change seamlessly through a continuous range of effective gear ratios and CVT also known as a single-speed transmission, stepless transmission, pulley transmission, or, in case of motorcycles, a twist-and-go. This contrasts with other mechanical transmissions that offer a set number of gear ratios. The suppleness of a CVT allows the input shaft to maintain a constant angular velocity. A continuously variable transmission (CVT) transfers power throughout a range of speed/torque ratios from engine input towards output, continuously exclusive of interruption. Contrast with either manual or conventional automatic transmissions that make use of discrete ratios as well as normally disengage when changing ratio. The CVT grouping includes infinitely variable transmissions (IVT) so that give a zero output speed within the operating range. The “Half Toroidal” type CVT scheme has basic component arrays. This work documents a successfully developed experiment of a “Half Toroidal” continuously variable transmission (CVT) by adjusting its geometrical arrangement of CVT design as well as compared the experimental results of torque, speed, and power delivered at the output disc with those obtained by a theoretical
