Abstract

See full text

The present invention relates to a seamless gearbox, particularly for motorcycles, which is mechanically operated e.g. by the rider's foot. The input shaft of the seamless gearbox of the present invention is split into two elements, each of them is connected to the “next” or “previous” gear, that are linked via the system to the torque input (e.g. clutch). The system according to a preferred embodiment of the present invention allows, via mechanical functionality only, to select only the appropriate of the two elements to transmit torque, based on relative speed between the two elements, and avoiding (for safety reasons) to have simultaneous torque transmission to both elements at the same time.
