Abstract
A mechatronic transmission for transmitting a torque from the drive shaft that can be supported axially on a shaft to an output shaft, the rotational speeds of which can have an arbitrary and variable ratio (stepless transmission). The transmission includes a coupling gear and a torsion spring, with the coupling gear rotatably mounted on the same shaft and connected to the output shaft by the torsion spring, and having a first coupling for producing and cancelling a rotationally fixed, planar, force-fitting first coupling between the drive shaft and the coupling gear. The transmission comprises a supporting device which is rotatable having a fixed transmission ratio of 1:X relative to the output shaft, where X can be any real number between approximately −10 and 1, and a second coupling for producing and cancelling a rotationally fixed, force-fitting second coupling between the supporting device and the coupling gear.
