Patent ID: 11247749

Abstract:
A drive assemblage is described for a vehicle drivable by muscle energy and/or—in particular additionally—by motor energy, to an electric bicycle, e-bike, or pedelec, having: a crank spindle rotatable around a rotation axis for receiving a first torque that is generated in particular by muscle energy; and a transfer device that is embodied to transfer the first torque from the crank spindle to an output drive element couplable to a drive wheel of the vehicle, and is embodied, by way of an—in particular automatically—shiftable spur gear transmission, for a variable conversion ratio, in which: the spur gear transmission has a first shiftable spur gear transmission and a second shiftable spur gear transmission separate therefrom; the first shiftable spur gear transmission and the second shiftable spur gear transmission have a common transmission output to the couplable output drive element; and the first shiftable spur gear transmission and the second shiftable spur gear transmission are couplable alternatingly and alternatively into the power and torque flow of the transfer device.
