<p>The transmission has a screw drive (30) attached between a foot pedal connection shaft (10) and a drive connection element (20) and comprising a guide in form of a helicoids section with constant or variable pitch. A coupling element (40) switchably connects a motor connection shaft (50) with the drive connection element, and is connected with the screw drive in an axial force transmitting manner. The coupling element separates the motor connection shaft from the drive connection element during negative torsional movement between the foot pedal connection shaft and the connection element. An independent claim is also included for a method for controlling coupling of a drive and a motor of an electric bicycle.</p> |
