Abstract
Nowadays, automakers have invested in new technologies in order to improve the efficiency of their
products. Giant automakers have taken an important step toward achieving this objective by designing
continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the
external load according to the optimum efficiency curve of engine and reducing fuel consumption beside,
making smooth start up and removing the shock caused by changing the gear ratio and making more
pleasurable driving. Considering the specifications of one of Iranian automaker products (the Saipa Pride
131), a CVT with a metal pushing belt and variable pulleys have been designed to replace its current
manual transmission system. The necessary parts and components for the CVT have been determined and
considering the necessary constraints, its mechanism and components have been designed.
