Abstract:
1. A vehicle transmission comprising: an input shaft connected to an external clutch; a sun gear connected to said input shaft; a plurality of planet gears drivingly connected to said sun gear; an annulus gear drivingly connected to said planet gears; a hydraulic pump drivingly connected to said input shaft, said hydraulic pump for pumping oil; a high pressure oil line hydraulically communicating with said hydraulic pump, said high pressure oil line hydraulically communicating to a region defined between said annulus gear and said planet gears, said pumped oil for changing the driving resistance of said planet gears to said annulus gear; an output shaft connected to said planet gears; an output bushing connected to said output shaft; a yoke connected to said output bushing; and wherein responsive to said driving resistance of said planet gears to said annulus gear causing said annulus gear to reverse its direction of roll, said vehicle transmission shifting from one gear to another.
