Independent power split transfer drivetrain for electric vehicles and a method thereof

An independent power split transfer drivetrain (100) for electric vehicles (EV), comprising:

• a. at least two prime movers comprising a first motor M1 for driving a plurality of wheels and a second motor M2 for driving a Power Take-Off (PTO);
• b. a transmission unit comprising a 2-Stage reduction gearbox which splits the power between a front and rear axle (101, 102) using a plurality of traction gear pairs (GP1, GP2, GP3, GP4, GP5, and GP6) and between a mid and rear PTO's (103, 104) using a plurality of PTO gear pairs (GP7, GP8, GP9 and GP10);
• c. a flexible coupling C1 connects an output shaft of the first motor M1 and the second motor M2 to the transmission unit;
• d. a shift sleeve S1 configured to assembled in between the traction gear pairs GP1 and GP2;
• wherein the 2-Stage reduction gearbox is configured to be in neutral stage and the traction gear pairs GP1, GP2 are rotated freely without engaging the output shaft when the vehicle is switched on,
• wherein the independent power split transfer drivetrain working on modes comprises:
• (i) two wheel drive (2WD) mode, the first motor M1 drives the rear axle (102), the output shaft of the first motor M1 rotates when an accelerator pedal of the vehicle is pressed, the power from the first Motor M1 is transmitted to the traction gear pair GP1 and GP2, the shift sleeve S1 engages with either traction gear pair GP1 or GP2 based on user selection of a direction of the shift using a range shift lever, the power is transmitted from either GP1 or GP2 to GP3 to GP7 to power the rear axle (102) for driving the rear wheels when shift sleeve S1 engages with either GP1 or GP2,
• (ii) four wheel drive (4WD) mode, the first motor M1 drives both the front and rear axle (101, 102), the output shaft of the first motor M1 rotates when the accelerator pedal of the vehicle is pressed, the power from the first Motor M1 is transmitted to the traction gear pair GP1 and GP2, the shift sleeve S1 engages with either traction gear pair GP1 or GP2 based on the direction of the shift when the user selects a high range speed using the range shift lever, the power is transmitted from either GP1 to GP3 to GP7 or GP2 to GP3 to GP7 to powers the rear axle (102) for driving the rear wheels when shift sleeve S1 engages with either GP1 or GP2 and simultaneously the power is transmitted from GP3 to GP4 to GP5 to GP6 to power the front axle (101) for driving the front wheels when shift sleeve S2 is engaged, and
• (iii) PTO motor mode:
• the second motor M2 drives PTOs, the output shaft of the second motor M2 rotates when the electrical lever is actuated, and the power is transmitted from the second Motor M2 to the traction gear pair GP8 and GP11, the power is transmitted from GP8 to GP9 to GP10 to power the mid PTO when a shift sleeve S3 engages with GP8, the GP11 directly powers the rear PTO when a shift sleeve S4 engages with GP11, and both the mid and rear PTOs are powered when shift sleeve S3 and S4 engages with GP8 and GP11.
