ABSTRACT:
A multiple gear transmission with magnetic control for vehicles or for use in drive technology includes an input shaft supported on a frame and an output shaft. The input shaft protrudes from the frame at least one end and the output shaft protrudes from the frame at one end. Transmission gear ratios with transmission wheels are embodied as gear trains or belt and chain drives and are located between the input shaft and the output shaft. Transmission wheels are supported in a rotatable manner on the input shaft or on the output shaft. The transmission wheels are connected to the input shaft or the output shaft in a torsionally fixed manner by a clutch mechanism. The transmission wheels are constantly in rotation during operation. A state of the clutch mechanism changes through the change of an additional magnetic field inside or in a direct vicinity of the clutch mechanism.
