Automatic friction wheel transmission

An automatic friction wheel transmission, comprising:

• a) an enclosed case;
• b) an input shaft assembly rotatively mounted through said enclosed case;
• and
• c) an output shaft assembly rotatively mounted through said enclosed case and operatively connected to said input shaft assembly for selective rotation therewith, wherein said enclosed case comprises:
• i) a lower portion that has said input shaft assembly and said output shaft assembly rotatively mounted therethrough;
• and
• ii) an upper portion that is replaceably attached to said lower portion of said enclosed case, by nuts and bolts, for allowing access to said input shaft assembly and said output shaft assembly, wherein said input shaft assembly comprises an input shaft that extends rotatively through, and is supported on, said lower portion of said enclosed case, by a pair of support bearings, wherein said input shaft of said input shaft assembly has a pair of ends that extend past said lower portion of said enclosed case, with one end thereof threadably engaging a nut and for being operatively connected to a prime mover, and with the other end thereof threadably engaging another nut, with said nut of said input shaft assembly and said another nut of said input shaft assembly preventing the unintentional removal of said input shaft assembly from said enclosed case, wherein said input shaft assembly further includes a sleeve that is disposed in said enclosed case and receives said input shaft of said input shaft assembly, wherein said sleeve of said input shaft assembly is biased towards the prime mover by a coil spring that receives said input shaft of said input shaft assembly, and which abuts against a support bearing of said pair of support bearings of said input shaft assembly.
