Abstract:
A transmission for vehicles and machinery for the purpose of changing engine speeds and torque for moving loads or rotating shafts, comprising:a) a transmission housing including an interior housing compartment and being connected to the engine;b) a rheological or magnetizable fluid within said interior compartment of said transmission housing;c) an input shaft and an output shaft mounted in said interior housing compartment in a parallel arrangement;d) a plurality of fixed gears mounted on said input shaft and being rotated by said input shaft;e) said output shaft having mounted thereon a plurality of electromagnetic clutch plates, each having an adjacent free rotating gear mounted on said output shaft to form a plurality of sets of electromagnetic clutch plates and free rotating gears;f) said plurality of fixed gears being meshed at all times with said free rotating gears on said output shaft;g) means for selecting one of said plurality of sets of electromagnetic clutch plates and free rotating gears for activating said output shaft into a forward or reverse rotational movement;h) means for transferring electric current from battery or power source to energize one or more of said electromagnetic clutch plates to create a magnetic force for pulling an adjacent free rotating gear axially along said output shaft to bond with said electromagnetic clutch plate to cause rotation of said output shaft.
