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.

Claim (Index 21):
A method for transmitting a torque or power from a drive shaft to an output shaft given an continuously variable transmission ratio using a transmission, the method comprising:\n (a) coupling the coupling wheel to the drive shaft with a first coupling as soon as the coupling wheel and drive shaft have the exact same rotational speeds, so as to tension a torsion spring and simultaneously transmit energy from the drive shaft to the output shaft via the torsion spring; (b) decoupling the coupling wheel from the drive shaft at a high angle of twist of the torsion spring, so as to allow the coupling wheel to freewheel and continue rotating as the rotational speed drops; (c) coupling the coupling wheel to the support device with a second coupling as soon as the coupling wheel and support device have the exact same rotational speeds, so as to transmit energy of the torsion spring to the output shaft; (d) decoupling the coupling wheel from the support device at a low angle of twist of the torsion spring, so as to allow the coupling wheel to rise again while freewheeling until such time as the coupling wheel once again rotates at exactly the same speed as the drive shaft as the rotational speed drops, wherein the process continues again with step (a).
