mechanical engineering. SUBSTANCE: stepless transmission has a body, primary and secondary shafts positioned in parallel, lever, lever turning control mechanism, and drum with multidisc friction variable-speed drive of internal contact. Transmission also includes output shaft and planetary adder. Carrier is secured to primary shaft. Epicycle is associated with secondary shaft through pair of gear-wheels. Sun gear of planetary adder is mounted on output shaft arranged coaxially with primary shaft. The invention provides for enlarged control range of stepless transmission gear ratio and reversible and neutral transmission. EFFECT: enhanced efficiency and reliability. 2 dwg
