This invention discloses a spinless multi-roller cone continuously variable transmission (CVT) unit, aiming to provide a CVT unit that avoids spin efficiency loss within its gear ratio range, is easy to manufacture, has a long lifespan, and provides high torque. Its key technical features are: the transmission unit consists of a spindle, input sleeve, output sleeve, input roller, output roller, force-transmitting cone, cone mounting shaft, and speed-regulating sleeve. Power is input through the input sleeve, passing sequentially through the input roller, force-transmitting cone, and output roller, and finally output through the output sleeve. A speed-regulating sleeve is arranged on the spindle, hinged to one end of the cone mounting shaft. During speed adjustment, the orientation of the force-transmitting roller is changed by moving the speed-regulating sleeve, and other traction elements follow and maintain contact. The working surface of the force-transmitting cone is a standard conical surface, while the input and output rollers are convex curved surfaces. This invention can be used to replace the transmission unit in a traction-type CVT, enabling the transmission to achieve spinless, efficient transmission with excellent overall performance.
