Automatic multi-level transmission for a vehicle

A differential gear device comprised of:

• a. first planetary gears (3) wherein said first planetary gears are installed in a first planetary carrier (2) which rotates by an input power axle (1), and a left side gear (4) and a right side gear (5) which is affixed on a first power axle (6) and a second power axle (7) which rotates by being interlocked with said first planet gears (3);
• b. a torque convertor wherein said torque convertor is comprised of a pump impeller (16) affixed onto said first planet carrier (2) of said differential gear device and rotating with said input power axle (1);
• a turbine runner (17) affixed onto said second power axle (7), and activating by said pump impeller (16);
• a stator (20) placed in the middle of said turbine runner (17) and said pump impeller (16);
• c. a control device wherein said control device is comprised of a multi-plate clutch (14) which activates by the motion of pressing a brake pedal, installed onto said second power axle (7);
• an one-way clutch (15) installed beside said multi-plate clutch, detaching said turbine runner from said second power axle (7) when it rotates faster than said turbine runner (17);
• d. a reduction gear device wherein said reduction device is comprised of a sun gear (8) affixed at the end of said first power axle (6);
• second planetary gears (12) interlocked with the sun gear in a planetary carrier (10) of an output power axle (9);
• a ring gear (13) affixed onto said second power axle (7) wrapping around said second planet gears (12).
